    Vulvovaginal candidiasis is the most prevalent vaginal infection worldwide and Candida albicans is its major agent. Vulvovaginal candidiasis is characterized by disruption of the vaginal microbiota composition, as happens following large spectrum antibiotic usage. Recent studies support the effectiveness of oral and local probiotic treatment for prevention of recurrent vulvovaginal candidiasis. Saccharomyces cerevisiae is a safe yeast used as, or for, the production of ingredients for human nutrition and health. Here, we demonstrate that vaginal administration of probiotic Saccharomyces cerevisiae live yeast (GI) and, in part, inactivated whole yeast Saccharomyces cerevisiae (IY), used as post-challenge therapeutics, was able to positively influence the course of vaginal candidiasis by accelerating the clearance of the fungus. This effect was likely due to multiple interactions of Saccharomyces cerevisiae with Candida albicans. Both live and inactivated yeasts induced coaggregation of Candida and consequently inhibited its adherence to epithelial cells. However, only the probiotic yeast was able to suppress some major virulence factors of Candida albicans such as the ability to switch from yeast to mycelial form and the capacity to express several aspartyl proteases. The effectiveness of live yeast was higher than that of inactivated whole yeast suggesting that the synergy between mechanical effects and biological effects were dominant over purely mechanical effects. The protection of epithelial cells to Candida-induced damage was also observed. Overall, our data show for the first time that Saccharomyces cerevisiae-based ingredients, particularly the living cells, can exert beneficial therapeutic effects on a widespread vaginal mucosal infection.

    Untreated bacterial vaginosis is related with many complications for non-pregnant women in reproductive age, most common from them are vaginal discharge and postoperative infections. The aim of our investigation was to compare the effectiveness of two therapeutic regimes which consist in Macmiror/Macmiror Complex alone and in combination with Feminella Vagi C for treatment of bacterial vaginosis (BV) and/or mycotic infection. 117 non-pregnant women with symptoms of vaginal infection were prospectively enrolled into two groups according their treatment. First group consist 66 women treated with Macmiror tablets and vaginal capsules followed with local application of Feminella Vagi C, the second group consist 54 women treated with Macmiror tablets and vaginal capsules only. The impact of treatment on clinical symptoms was observed at the end of medication and 20 days after it. Microbiological testing was repeated 20 days after treatment. Over than 80% (78.6 divided by 86.7%) of the cases with vaginal infection (BV and mycotic one) were successfully treated with Macmiror/Macmiror Complex. Supplement treatment with Feminella Vagi C lead to higher percentage of clinically recovery (86.7% vs 84.6%), better microbiological cleaning (86.7% vs 82.1%) and longer effect of treatment. Used medication showed higher efficacy against BV than to fungal infection. According obtained results we may conclude that bacterial vaginosis was better treated with multipurpose treatment (Nifuratel, Nistatin and vit. C) than with Macmiror alone.

    Full Text Available A contraceptive vaginal ring (CVR containing Nestorone® (NES and ethinyl estradiol (EE that is reusable for 1- year (13 cycles is under development. This study assessed effects of this investigational CVR on the incidence of vaginal infections and change in vaginal microflora.There were 120 women enrolled into a NES/EE CVR Phase III trial and a microbiology sub-study for up to 1- year of cyclic product use. Gynecological examinations were conducted at baseline, the first week of cycle 6 and last week of cycle 13 (or during early discontinuation visits. Vaginal swabs were obtained for wet mount microscopy, Gram stain and culture. The CVR was removed from the vagina at the last study visit and cultured. Semi-quantitative cultures for Lactobacillus, Gardnerella vaginalis, Enterococcus faecalis, Staphylococcus aureus, Escherichia coli, anaerobic gram negative rods (GNRs, Candida albicans and other yeasts were performed on vaginal and CVR samples. Vaginal infections were documented throughout the study.Over 1- year of use, 3.3% of subjects were clinically diagnosed with bacterial vaginosis, 15.0% with vulvovaginal candidiasis, and 0.8% with trichomoniasis. The detection rate of these three infections did not change significantly from baseline to either Cycle 6 or 13. Nugent scores remained stable. H2O2-positive Lactobacillus dominated vaginal flora with a non-significant prevalence increase from 76.7% at baseline to 82.7% at cycle 6 and 90.2% at cycle 13, and a median concentration of 107 colony forming units (cfu per gram. Although anaerobic GNRs prevalence increased significantly, the median concentration decreased slightly (104 to 103cfu per gram. There were no significant changes in frequency or concentrations of other pathogens. High levels of agreement between vaginal and ring surface microbiota were observed.Sustained use of the NES/EE CVR did not increase the risk of vaginal infection and was not disruptive to the vaginal ecosystem

    Vulvovaginal candidiasis is a condition that affects a great number of fertile women. It is considered the second cause of genital infection after vaginosis due to GAM complex. Candida albicans is the most frequent isolated species from vaginal discharge. However, sometimes more than one yeast species could be found in the same clinical sample that are more resistant to antifungal drugs. Nowadays, it is necessary to identify properly up to species level the isolated microorganism and to determine the antifungal susceptibility profile. One hundred strains obtained from vaginal discharge of 94 patients suffering acute vulvovaginal candidiasis were studied. The identification of the isolates showed: C. albicans 86%, Candida glabrata 6%, Candida inconspicua 3%, Candida krusei 2% and Candida intermedia, Candida holmii and Trichosporon asahii one case each. Minimal inhibitory concentrations (MIC) of all the yeasts against fluconazole and albaconazole were performed. C. glabrata, C. krusei and C. inconspicua were the most resistant against fluconazole, on the other hand albicans was susceptible to this drug. All the isolates presented MIC against albaconazole much lower than fluconazole.

    Full Text Available Bacground/Aim. Vaginal and cervical swab culture is still very common procedure in our country’s everyday practice whereas simple and rapid diagnostic methods have been very rarely used. The aim of this study was to show that the employment of simple and rapid diagnostic tools [vaginal fluid wet mount microscopy (VFWMM, vaginal pH and potassium hydroxide (KOH test] offers better assessment of vaginal environment than standard microbiologic culture commonly used in Serbia. Methods. This prospective study included 505 asymptomatic pregnant women undergoing VFWMM, test with 10% KOH, determination of vaginal pH and standard culture of cervicovaginal swabs. Combining findings from the procedures was used to make diagnoses of bacterial vaginosis (BV and vaginitis. In addition, the number of polymorphonuclear leukocytes (PMN was determined in each sample and analyzed along with other findings. Infections with Candida albicans and Trichomonas vaginalis were confirmed or excluded by microscopic examination. Results. In 36 (6% patients cervicovaginal swab cultures retrieved several aerobes and facultative anaerobes, whereas in 52 (11% women Candida albicans was isolated. Based on VFWMM findings and clinical criteria 96 (19% women had BV, 19 (4% vaginitis, and 72 (14% candidiasis. Of 115 women with BV and vaginitis, pH 4.5 was found in 5, and of 390 with normal findings 83 (21% had vaginal pH 4.5. Elevated numbers of PMN were found in 154 (30% women - in 83 (54% of them VFWMM was normal. Specificity and sensitivity of KOH test and vaginal pH determination in defining pathological vaginal flora were 95% and 81%, and 79% and 91%, respectively. Conclusion. Cervicovaginal swab culture is expensive but almost non-informative test in clinical practice. The use of simpler and rapid methods as vaginal fluid wet mount microscopy, KOH test and vaginal pH offers better results in diagnosis, and probably in the treatment and prevention of sequels of vaginal

    Full Text Available In modern obstetrical and gynecological practice, the problem of disturbing the vaginal microflora is one of the most urgent because of the possibility of developing a whole complex of complications affecting the reproductive function of women. Mixed variants of vaginal infections have been little studied, nevertheless, they must be distinguished, since different forms of coexistence of pathogens require an individual therapeutic approach. Objective – evaluation of the effectiveness of the use of a new combination gel form preparation for vaginal infections in pregnant women. Methods of research. The study included 200 pregnant women with vaginal infections: 100 women made up the basic group, received treatment with a new gel preparation Metrogyl Plus within 5 days. The comparison group consisted of 100 patients treated with Clion-D 100. The second stage involved lactobacilli providing colonization resistance of the vaginal biotope. Results. Efficacy after the end of treatment after 1 month was 99 % in the main group, 94 % in the comparison group (p = 0,12, relapses after treatment at 3 months were revealed in 2 % and 10 % of the observations, respectively, in the study groups (p = 0,02. Placental disorders, the threat of spontaneous abortion, polyhydramnios, gestational pyelonephritis, edema caused by pregnancy, and preeclampsia were collectively observed in the main group less frequently than in the comparison group (p = 0,025. Complications of childbirth and the postpartum period are also noted less frequently in the main group than in the comparison group, which is associated with a much smaller number of relapses after treatment (p = 0,004. Conclusion. Treatment of vaginal infections with a new gel form preparation in pregnant women is highly effective and is 99 %. The number of relapses after treatment with the combined preparation in the form of a gel is only 2 % after 3 months. Consequently, the use of an effective

    Full Text Available In order to evaluate the pathogenicity of yeasts isolated from vaginal secretion of pregnant and non-pregnant women - stored in mineral oil at the URM Mycology Collection, Department of Mycology, Federal University of Pernambuco - 30 samples belonging to the genera Candida, Rhodotorula, Trichosporon, and Kloeckera, were studied regarding their pathogenic characteristics, ability to grow at room temperature (28°C ± 1°C, 37°C, and 42°C for 72 hours, and production of both phospholipase and proteinase. Results showed that all 30 isolates (100% were able to grow at room temperature and 37°C, and that 17 samples (57% were able to grow at 42°C. Evaluation of enzymatic activity showed protease activity in only two isolates (7%, namely C. maritima and C. obtusa. Phospholipase activity was detected in 20 isolates (67% using soy lecithin as substrate at different temperatures. The characterization of yeasts isolated from vaginal secretion and determination of their enzymatic activity may contribute to understanding the epidemiology of vulvovaginitis and assist in the treatment of patients.

    Kim, Jun-Mo; Park, Yoo Jin

    2017-12-01

    Bacterial vaginosis (BV) and complicated vulvovaginal candidiasis (VVC) are frequently occurring vaginal infections in postmenopausal women, caused by an imbalance in vaginal microflora. Postmenopausal women suffer from decreased ovarian hormones estrogen and progesterone. A normal, healthy vaginal microflora mainly comprises Lactobacillus species (spp.), which act beneficially as a bacterial barrier in the vagina, interfering with uropathogens. During premenopausal period, estrogen promotes vaginal colonization by lactobacilli that metabolizing glycogen and producing lactic acid, and maintains intravaginal health by lowering the intravaginal pH level. A lower vaginal pH inhibits uropathogen growth, preventing vaginal infections. Decreased estrogen secretion in postmenopausal women depletes lactobacilli and increases intravaginal pH, resulting in increased vaginal colonization by harmful microorganisms (e.g., Enterobacter , Escherichia coli , Candida , and Gardnerella ). Probiotics positively effects on vaginal microflora composition by promoting the proliferation of beneficial microorganisms, alters the intravaginal microbiota composition, prevents vaginal infections in postmenopausal. Probiotics also reduce the symptoms of vaginal infections (e.g., vaginal discharge, odor, etc.), and are thus helpful for the treatment and prevention of BV and VVC. In this review article, we provide information on the intravaginal mechanism of postmenopausal vaginal infections, and describes the effectiveness of probiotics in the treatment and prevention of BV and VVC.

    This study aimed to investigate the application of Origanum vulgare L. essential oil (EO) as an alternative antimicrobial agent against vaginal infections. Microdilution methods were applied for the detection of the minimal inhibitory (MIC) and the minimal bactericidal/fungicidal (MBC/MFC) concentration of 15 clinical strains originating from women with symptoms of vaginal infection. Optical density determination (OD) was used for detection of the Candida growth rate. Staining with DAPI was used to detect the influence of EO on nuclear condensation and fragmentation, while the brine shrimp bioassay was used to determine the toxicity of EO. Chemical composition analysis was done using GS-MS. According to the MIC and MBC/MFC values, the most susceptible strains to EO were: Escherichia coli 1, E. coli 2, Staphylococcus aureus 3 and Candida albicans 1-3. Inhibition of C. albicans filamentation was detected at 0·45 μl ml(-1) . The obtained inhibition (%) from Candida growth curves points to a shorter period of time (24 h) for determining IC50 as MIC and IC99 as MFC value. These values could be recommended as valid parameters for the faster detection of the effectiveness of EO on Candida isolates.

    Infectious vaginitis occurs when the normal vaginal flora is disrupted; it may arise when saprophytes overwhelm the host immune response, when pathogenic organisms are introduced into the vagina or when changes in substrate allow an imbalance of microorganisms to develop. Examples of these types of vaginitis include the presence of chronic fungal infection in women with an inadequate cellular immune response to the yeast, the introduction of trichomonads into vaginal epithelium that has a sufficient supply of glycogen, and the alteration in bacterial flora, normally dominated by Lactobacillus spp., and its metabolites that is characteristic of "nonspecific vaginitis". The authors review microbiologic and clinical aspects of the fungal, protozoal and bacterial infections, including the interactions of bacteria thought to produce nonspecific vaginitis, that are now recognized as causing vaginitis. Other causes of vaginitis are also discussed.

  9. An emerging mycoplasma associated with trichomoniasis, vaginal infection and disease.

    Directory of Open Access Journals (Sweden)

    Jennifer M Fettweis

    Full Text Available Humans are colonized by thousands of bacterial species, but it is difficult to assess the metabolic and pathogenic potential of the majority of these because they have yet to be cultured. Here, we characterize an uncultivated vaginal mycoplasma tightly associated with trichomoniasis that was previously known by its 16S rRNA sequence as "Mnola." In this study, the mycoplasma was found almost exclusively in women infected with the sexually transmitted pathogen Trichomonas vaginalis, but rarely observed in women with no diagnosed disease. The genomes of four strains of this species were reconstructed using metagenome sequencing and assembly of DNA from four discrete mid-vaginal samples, one of which was obtained from a pregnant woman with trichomoniasis who delivered prematurely. These bacteria harbor several putative virulence factors and display unique metabolic strategies. Genes encoding proteins with high similarity to potential virulence factors include two collagenases, a hemolysin, an O-sialoglycoprotein endopeptidase and a feoB-type ferrous iron transport system. We propose the name "Candidatus Mycoplasma girerdii" for this potential new pathogen.

    We present a case report of secondary vaginal cancer after complete hysterectomy due to myoma that was complicated by low-grade cervical intraepithelial neoplasia (CIN I) and human papilloma virus (HPV) infection. After complete hysterectomy, the HPV DNA level in the vaginal tissue was obviously increased, and vaginal cancer was diagnosed 6 months later. We conclude that HPV infection can cause vaginal cancer after complete hysterectomy in cases complicated by CIN. Therefore, HPV should be regularly assessed during the postoperative follow-up period.

    In humans, the vaginal microbiota is thought to be the first line of defense again pathogens including Chlamydia trachomatis. The guinea pig has been extensively used as a model to study chlamydial infection because it shares anatomical and physiological similarities with humans, such as a squamous vaginal epithelium as well as some of the long-term outcomes caused by chlamydial infection. In this study, we aimed to evaluate the guinea pig-C. caviae model of genital infection as a surrogate for studying the role of the vaginal microbiota in the early steps of C. trachomatis infection in humans. We used culture-independent molecular methods to characterize the relative and absolute abundance of bacterial phylotypes in the guinea pig vaginal microbiota in animals non-infected, mock-infected or infected by C. caviae. We showed that the guinea pig and human vaginal microbiotas are of different bacterial composition and abundance. Chlamydia caviae infection had a profound effect on the absolute abundance of bacterial phylotypes but not on the composition of the guinea pig vaginal microbiota. Our findings compromise the validity of the guinea pig-C. caviae model to study the role of the vaginal microbiota during the early steps of sexually transmitted infection. © FEMS 2015.

    Complications related to the diagnosis and treatment of Trichomonas vaginalis infection, as well as the association between T. vaginalis infection and increased transmission of and susceptibility to human immunodeficiency virus, highlight the need for alternative interventions. We tested a human-safe, aluminum hydroxide-adjuvanted whole-cell T. vaginalis vaccine for efficacy in a BALB/c mouse model of vaginal infection. A whole-cell T. vaginalis vaccine was administered subcutaneously to BALB/c mice, using a prime-boost vaccination schedule. CD4(+) T-cell infiltration in the murine vaginal tissue and local and systemic levels of immunoglobulins were measured at time points up to 4 weeks following infection. Vaccination reduced the incidence and increased the clearance of T. vaginalis infection and induced both systemic and local humoral immune responses. CD4(+) T cells were detected in vaginal tissues following intravaginal infection with T. vaginalis but were not seen in uninfected mice. The presence of CD4(+) T cells following T. vaginalis infection can potentially increase susceptibility to and transmission of human immunodeficiency virus. The vaccine induces local and systemic immune responses and confers significantly greater protection against vaginal infection than seen in unvaccinated mice (P vaginalis infection that could also influence the incidence of human immunodeficiency virus infection. © The Author 2015.

RESULTS: Candida was present in 27.6% of the samples. Candida albicans was the predominant species (74%, followed by Candida glabrata (14.5%, Candida tropicalis (7,3% and Candida parapsilosis (4,3%. All the C. albicans isolates were susceptible to anfotericin B and only one sample of non-albicans showed greater MIC (2mg/mL. 5.9% of C. albicans strains were susceptible-dose dependent to FLU and 9,8% resistant. Only one sample showed resistance to itraconazol, with CIM 8mg/mL. In the species non-albicans, 11.8% of the isolates were considered resistant to fluconazol and 23.5% to itraconazol. CONCLUSION: Candida albicans is the most frequent in the vaginal microenviroment, however non-albicans are common vaginal isolates even in a primary care population. The species isolated are less susceptible to fluconazole and itraconazole than most C. albicans, showing the importance of the performance of the identification tests and susceptibility to antifungal agents of vulvovaginal candidiasis.

    Currently, there are few studies on candidaemia in the severely burned patient. These patients share the same risk factors for invasive fungal infections as other critically ill patients, but have certain characteristics that make them particularly susceptible. These include the loss of skin barrier due to extensive burns, fungal colonisation of the latter, and the use of hydrotherapy or other topical therapies (occasionally with antimicrobials). In addition, the increased survival rate achieved in recent decades in critically burned patients due to the advances in treatment has led to the increase of invasive Candida infections. This explains the growing interest in making an earlier and more accurate diagnosis, as well as more effective treatments to reduce morbidity and mortality of candidaemia in severe burned patients. A review is presented on all aspects of the burned patient, including the predisposition and risk factors for invasive candidiasis, pathogenesis of candidaemia, underlying immunodeficiency, local epidemiology and antifungal susceptibility, evolution and prognostic factors, as well as other non-Candida yeast infections. Finally, we include specific data on our local experience in the management of candidaemia in severe burned patients, which may serve to quantify the problem, place it in context, and offer a realistic perspective.

    We planned to develop predator-prey models using Paramecium and yeast, but they have not been empirically examined since work by Gause in the 1930s. Therefore, we evaluated if Paramecium aurelia ingests and grows on eight yeasts. Recognising that it ingested yeasts but could not grow, we assessed if it might grow on other yeasts, by empirically parameterising a predator-prey model that relies on ingestion, not growth. Simulations were compared to P. aurelia-yeast time-series data, from Gause. We hypothesised that if the model simulated predator-prey dynamics that mimicked the original data, then possibly P. aurelia could grow on yeast; simulations did not mimic the original data. Reviewing works by Gause exposed two issues: experiments were undoubtedly contaminated with bacteria, allowing growth on bacteria, not yeast; and the population cycle data cannot be considered a self-sustaining time series, as they were manipulated by adding yeast and ciliates. We conclude that past and future work should not rely on this system, for either empirical or theoretical evaluations. Finally, although we show that P. aurelia, P. caudatum, Euplotes patella, and Blepharisma sp. cannot grow on yeast, Tetrahymena pyriformis and Colpidium striatum can; these may provide models to explore predator-prey dynamics. © 2016 The Author(s) Journal of Eukaryotic Microbiology © 2016 International Society of Protistologists.

    Human papillomavirus (HPV) is the most important causative agent of cervical cancers worldwide. However, our understanding of how the vaginal microbiota might be associated with HPV infection is limited. In addition, the influence of human genetic and physiological factors on the vaginal microbiota is unclear. Studies on twins and their families provide the ideal settings to investigate the complicated nature of human microbiota. This study investigated the vaginal microbiota of 68 HPV-infected or uninfected female twins and their families using 454-pyrosequencing analysis targeting the variable region (V2-V3) of the bacterial 16S rRNA gene. Analysis of the vaginal microbiota from both premenopausal women and HPV-discordant twins indicated that HPV-positive women had significantly higher microbial diversity with a lower proportion of Lactobacillus spp. than HPV-negative women. Fusobacteria, including Sneathia spp., were identified as a possible microbiological marker associated with HPV infection. The vaginal microbiotas of twin pairs were significantly more similar to each other than to those from unrelated individuals. In addition, there were marked significant differences from those of their mother, possibly due to differences in menopausal status. Postmenopausal women had a lower proportion of Lactobacillus spp. and a significantly higher microbiota diversity. This study indicated that HPV infection was associated with the composition of the vaginal microbiota, which is influenced by multiple host factors such as genetics and menopause. The potential biological markers identified in this study could provide insight into HPV pathogenesis and may represent biological targets for diagnostics.

    Although implied by other models, proof that Langerhans cells (LCs) in the human vagina participate in dissemination of infectious human immunodeficiency virus type 1 (HIV-1) has been lacking. Here, we show that LCs migrate from HIV-1-exposed vaginal epithelia and pass infectious virus to CD4+ T cells without being productively infected themselves, and we point to a pathway that might enable HIV-1 to avoid degradation in vaginal LCs. Transport by migratory LCs to local lymphatics in a nonprod...

    Bacterial vaginosis (BV) is a dysbiosis of the vaginal flora characterized by a shift from a Lactobacillus-dominant environment to a polymicrobial mixture including Actinobacteria and gram-negative bacilli. BV is a common vaginal condition in women and is associated with increased risk of sexually transmitted infection and adverse pregnancy outcomes such as preterm birth. Gardnerella vaginalis is one of the most frequently isolated bacterial species in BV. However, there has been much debate in the literature concerning the contribution of G. vaginalis to the etiology of BV, since it is also present in a significant proportion of healthy women. Here we present a new murine vaginal infection model with a clinical isolate of G. vaginalis. Our data demonstrate that this model displays key features used clinically to diagnose BV, including the presence of sialidase activity and exfoliated epithelial cells with adherent bacteria (reminiscent of clue cells). G. vaginalis was capable of ascending uterine infection, which correlated with the degree of vaginal infection and level of vaginal sialidase activity. The host response to G. vaginalis infection was characterized by robust vaginal epithelial cell exfoliation in the absence of histological inflammation. Our analyses of clinical specimens from women with BV revealed a measureable epithelial exfoliation response compared to women with normal flora, a phenotype that, to our knowledge, is measured here for the first time. The results of this study demonstrate that G. vaginalis is sufficient to cause BV phenotypes and suggest that this organism may contribute to BV etiology and associated complications. This is the first time vaginal infection by a BV associated bacterium in an animal has been shown to parallel the human disease with regard to clinical diagnostic features. Future studies with this model should facilitate investigation of important questions regarding BV etiology, pathogenesis and associated complications.

We found that - when compared with the lactobacillus vaginal suppositories - the high dose vitamin D vaginal treatment might be more effective. Vitamin D showed very good anti-inflammatory effects. In the survey after six weeks therapy 79% of the women had “less vaginal problems,” “less discharge” and “less problems with the sexual intercourse.” Objectively after six weeks therapy only 7% of the patients still had bacterial and/or fungal vaginal infections that required a treatment. We found that vitamin D is reabsorbed by the vaginal mucosa, but the reabsorption may be individually very different. In the CIN 1 group we found six weeks after treatment good antidysplastic effects, in the CIN 2 group we often found no or only temporary antidysplastic effects. So this vaginal vitamin D treatment method might be an option for the therapy and prevention of chronical cervical infections and maybe of a cervic dysplasia CIN 1 (good antiinflammatory effects, antidysplastic effects). This small study is not representative. We need much bigger studies with much more dates and with a longer follow up. Caution: At the moment we do not know, if the vaginal vitamin D treatment with 12500 IE is possible in pregnancy. We have no experience. Therefore we recommend an effective contraception during the application. PMID:24605180

    Bacterial vaginosis, candidal, trichomonal and Gonococcal vaginal infections are a major health problems associated with gynecologic complications and increase in replication, shedding and transmission of HIV and other STIs in women of reproductive age. The study aimed at determining the prevalence of common vaginal infections and antimicrobial susceptibility profiles of aerobic bacterial isolates in women of reproductive age, attending Felegehiwot referral Hospital. A hospital based cross sectional study was conducted from May to November, 2013. Simple random sampling technique was used. Demographic variables were collected using a structured questionnaire. Clinical data were collected by physicians. Two vaginal swab specimens were collected from each participant. Wet mount and Gram staining were carried out to identify motile T.vaginalis, budding yeast and clue cells. All vaginal specimens were cultured for aerobic bacterial isolates using standard microbiology methods. Antimicrobial susceptibility was performed using disc diffusion technique as per the standard by Kirby-Bauer method. The results were analyzed using descriptive, chi-square and fisher's exact test as appropriate. A total of 409 women in reproductive age (15 - 49 years) participated in the study. The median age of the women was 28 years. Overall, 63 (15.4 %) of women had vaginal infections. The proportion of vaginal infection was higher in non-pregnant (17.3 %) than pregnant women (13.3 %) (P = 0.002). The most common identified vaginal infections were candidiasis (8.3 %) and bacterial vaginosis (2.8 %) followed by trichomoniasis (2.1 %). The isolation rate of N. gonorrhoeae and group B Streptococcus colonization was 4 (1 %) and 6 (1.2 %), respectively. Bacterial vaginosis was higher in non-pregnant (5.6 %) than pregnant women (0.5 %) (P = 0.002). Religion, age, living in rural area and having lower abdominal pain were significantly associated with bacterial vaginosis and

    This review aimed to synthesize and analyze the diagnostic accuracy and the likelihood of providing correct treatment of the syndromic approach Vaginal Discharge Flowchart in managing cervical infections caused by Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT), and vaginal infections caused by Trichomonas vaginalis (TV) and Bacterial vaginosis (BV) and Candida albicans. This review will inform updating the WHO 2003 guidelines on Vaginal Discharge syndromic case management. A systematic review was conducted on published studies from 01-01-2000 to 30-03-2015 in multiple databases. Studies evaluating the diagnostic accuracy and validation of the WHO Vaginal Discharge Flowchart were included. Validation parameters including sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) and the 95% confidence intervals for the different types of the flowchart were taken as outcomes, re-calculated, and analysed using a fixed model meta-analysis for data pooling. The level of agreement between the index and reference test were determined by the Cohen's Kappa co-efficiency test. Each individual study was assessed on quality using the QUADAS-2 tool. The search yielded 2,845 studies of which 16 met the eligibility criteria for final analysis. The diagnostic performance to identify cervical infections was low and resulted in a high proportion of over and missed treatment. The four flowcharts had a sensitivity between 27.37% in history and risk assessment and 90.13% with microscopy, with the inverse in specificity rates. The treatment performances between the flowcharts were inconsistent. The same applies to the use of vaginal discharge flowchart for treating vaginal infections. For vaginal infections the vaginal discharge flowchart had a good performance in flowchart 3 with 91.68% of sensitivity; 99.97% specificity; 99.93% PPV and 0.02% who missed their treatment and 8.32% of women who were over treated by the vaginal discharge

    Full Text Available Abstract Background Vaginal candidiasis is a frequent and common distressing disease affecting up to 75% of the women of fertile age; most of these women have recurrent episodes. Essential oils from aromatic plants have been shown to have antimicrobial and antifungal activities. This study was aimed at assessing the anti-fungal activity of essential oil from Mentha suaveolens (EOMS in an experimental infection of vaginal candidiasis. Methods The in vitro and in vivo activity of EOMS was assessed. The in vitro activity was evaluated under standard CLSI methods, and the in vivo analysis was carried out by exploiting a novel, non-invasive model of vaginal candidiasis in mice based on an in vivo imaging technique. Differences between essential oil treated and saline treated mice were evaluated by the non-parametric Mann-Whitney U-test. Viable count data from a time kill assay and yeast and hyphae survival test were compared using the Student's t-test (two-tailed. Results Our main findings were: i EOMS shows potent candidastatic and candidacidal activity in an in vitro experimental system; ii EOMS gives a degree of protection against vaginal candidiasis in an in vivo experimental system. Conclusions This study shows for the first time that the essential oil of a Moroccan plant Mentha suaveolens is candidastatic and candidacidal in vitro, and has a degree of anticandidal activity in a model of vaginal infection, as demonstrated in an in vivo monitoring imaging system. We conclude that our findings lay the ground for further, more extensive investigations to identify the active EOMS component(s, promising in the therapeutically problematic setting of chronic vaginal candidiasis in humans.

  10. Vaginal versus Obstetric Infection Escherichia coli Isolates among Pregnant Women: Antimicrobial Resistance and Genetic Virulence Profile.

    Emma Sáez-López

    Full Text Available Vaginal Escherichia coli colonization is related to obstetric infections and the consequent development of infections in newborns. Ampicillin resistance among E. coli strains is increasing, which is the main choice for treating empirically many obstetric and neonatal infections. Vaginal E. coli strains are very similar to extraintestinal pathogenic E. coli with regards to the virulence factors and the belonging to phylogroup B2. We studied the antimicrobial resistance and the genetic virulence profile of 82 E. coli isolates from 638 vaginal samples and 63 isolated from endometrial aspirate, placental and amniotic fluid samples from pregnant women with obstetric infections. The prevalence of E. coli in the vaginal samples was 13%, which was significant among women with associated risk factors during pregnancy, especially premature preterm rupture of membranes (p<0.0001. Sixty-five percent of the strains were ampicillin-resistant. The E. coli isolates causing obstetric infections showed higher resistance levels than vaginal isolates, particularly for gentamicin (p = 0.001. The most prevalent virulence factor genes were those related to the iron uptake systems revealing clear targets for interventions. More than 50% of the isolates belonged to the virulent B2 group possessing the highest number of virulence factor genes. The ampicillin-resistant isolates had high number of virulence factors primarily related to pathogenicity islands, and the remarkable gentamicin resistance in E. coli isolates from women presenting obstetric infections, the choice of the most appropriate empiric treatment and clinical management of pregnant women and neonates should be carefully made. Taking into account host-susceptibility, the heterogeneity of E. coli due to evolution over time and the geographical area, characterization of E. coli isolates colonizing the vagina and causing obstetric infections in different regions may help to develop interventions and avoid the

    Full Text Available BACKGROUND: Vulvovaginal candidiasis (VVC is the second most common vaginal infection. HIV-infection is a risk factor for this infection. OBJECTIVE: To determine the frequency of VVC and to describe the main Candida species isolated and their susceptibility to antifungal drugs in HIV-infected patients, compared to HIV-uninfected women in Salvador, Brazil. METHODS: Cross-sectional study including a group of 64 HIV-infected women and 76 uninfected women, followed up at the AIDS reference center and at the Gynecological Clinic of Escola Bahiana de Medicina e Saúde Pública (Salvador, Bahia, Brazil. RESULTS: Frequency of Candida spp. was higher in HIV-infected women (29.7% than in HIV-uninfected controls (14.5% (p = 0.02. The odds ratio value for vulvovaginal candidiasis in HIV-infected patients was 2.6 (95% CI: 1.07 - 6.32 p = 0.03. Candida albicans was the most commonly isolated species in both HIV-infected (52.3% and uninfected women (85.7%, followed by C. parapsolis in 17.6% and 14.3%, respectively. In HIV-infected women, C. glabrata, C. parapsilosis, and a coinfection of C. albicans and C. glabrata were also identified. There was no significant difference between Candida species isolated from the vaginal mucosa of women with VVC and colonization of the vaginal mucosa of HIV-infected and HIV-uninfected women. One C. glabrata isolate from an HIV-infected patient was resistant to fluconazole and other two isolates exhibited a dose-dependent susceptibility. CONCLUSION: Our results confirm a higher frequency of Candida spp. isolated from the vaginal mucosa of HIV-infected women and a broader spectrum of species involved. Only Candida glabrata isolates showed decreased susceptibility to fluconazole.

    , Candida tropicalis, e Candida guillermondii, o que pode ser explicado pelo uso inadequado de medicamentos e tratamento empírico.PURPOSE: to characterize, phenotypically, yeasts isolated from the vaginal content of 223 symptomatic (S and asymptomatic (A adult women with vulvovaginitis, and to determine the clinical indicators which may lead to the appearance of signs and symptoms related to the mucosa involvement by this pathology. METHODS: a questionnaire with open and closed questions on epidemiological clinical data was applied initially. Then, mycological diagnosis with sowing in Chrom Agar Candida was done, followed by micro-morphological and biochemical identification. Specific methods for the detection of the virulence factors, proteinase and phospholipase were employed. Statistical analysis was performed through χ2 and Pearson's χ2 tests. RESULTS: the most prevalent species found was Candida albicans (87%, S and 67%, A followed by Candida glabrata (4%, S e 17% A. The number of women reporting the use of contraceptives was higher among the symptomatic, 77%. In the two groups studied, about 87% of the women presented regular menstrual cycles and 57% were married with ages between 30 to 40 years old. Concerning the sexual practices, there has been concomitance among anal, oral and vaginal habits from the patients. Only Candida albicans produced the virulence factor phospholipase in 37.5% of them. Proteinase has been detected in Candida albicans, Candida glabrata and Candida parapsilosis. This latter virulence factor was mainly associated to isolates from symptomatic patients. CONCLUSIONS: it is a fact that the vaginal mucosa can be colonized and infected by yeasts, with several Candida species present. Nevertheless, Candida albicans is the most prevalent in the vaginal mucosa of adult women. It is evident the emergence of non-albicans Candida species, some of them with intrinsic resistance to azolics, such as Candida glabrata, Candida parapsilosis, Candida

    Full Text Available Vaginal infections (vaginosis globally affect more than 15% of the female population of reproductive age. However, diagnosis of vaginosis and differentiating between the three common types: bacterial vaginosis (BV, vulvovaginal candidiasis (VVC, and trichomoniasis are challenging. Elevated levels of the biogenic amines, trimethylamine (TMA, putrescine, and cadaverine have been found in vaginal discharge fluid of women with vaginosis. Ion mobility spectrometry (IMS is particularly suitable for measurement of amines even in complex biological matrices due to their high proton affinity and has been shown to be suitable for the diagnosis of vaginal infections. Recent developments that have increased the accuracy of the technique for diagnosis of BV and simplified sample introduction are described here.

    The identification of the host defence peptides as target effectors in the innate defence of the uro-genital tract creates new translational possibilities for immunomodulatory therapies, specifically vaginal therapies to treat women suffering from rUTI, particularly those carrying the TLR5_C1174T SNP. Urinary tract infections (UTIs) are a microbial disease reported worldwide. Women are particularly susceptible with many suffering debilitating recurrent (r) infections. Treatment is by antibiotics, but such therapy is linked to antibiotic resistance and re-infection. This study explored the innate protective mechanisms of the urogenital tract with the aim of boosting such defences therapeutically. Modelling UTIs in vitro, human vaginal and bladder epithelial cells were challenged with uropathogenic Escherichia coli (CFT073) and microbial PAMPs including flagellin, LPS and peptidoglycan. Flagellin functioning via the TLR5/NFκB pathway was identified as the key UPEC virulence factor causing a significant increase (P < 0.05) in the production of the host-defence peptide (HDP), BD2. BD2-depleted urine samples from bladder infected mice supported increased UPEC growth, strengthening the significance of the HDPs in protecting the urogenital tissues from infection. Clinically, vaginal-douche BD2 concentrations were reduced (p < 0.05) in women suffering rUTIs, compared to age-matched healthy controls with concentrations further decreased (p < 0.05) in a TLR5 392Stop SNP rUTI subgroup. Topical vaginal estrogen treatment increased (p < 0.001) BD2 concentrations in all women, including those carrying the SNP. These data identify therapeutic and antibiotic sparing roles for vaginal immunomodulatory agents that specifically target HDP induction, facilitate bacterial killing and disrupt the UPEC infection cycle.

    Full Text Available Abstract Background Vaginal pH is related to genital tract inflammation and changes in the bacterial flora, both suggested cofactors for persistence of human papillomavirus (HPV infection. To evaluate the relationship between vaginal pH and HPV, we analyzed data from our large population-based study in Guanacaste, Costa Rica. We examined vaginal pH and the risk of HPV infection, cytological abnormalities, and C. trachomatis infection. Methods Our study included 9,165 women aged 18-97 at enrollment with a total of 28,915 visits (mean length of follow-up = 3.4 years. Generalized estimating equations were used to evaluate the relationship between vaginal pH and HPV infection (both overall and single versus multiple types and low-grade squamous intraepithelial lesions (LSIL, the cytomorphic manifestation of HPV infection. The relationship between enrollment vaginal pH and C. trachomatis infection was assessed by logistic regression. Results were stratified by age at visit. Results Detection of HPV was positively associated with vaginal pH, mainly in women C. trachomatis DNA was associated with increased vaginal pH in women Conclusions Our findings suggest a possible association of the cervical microenvironment as a modifier of HPV natural history in the development of cervical precancer and cancer. Future research should include studies of vaginal pH in a more complex assessment of hormonal changes and the cervicovaginal microbiome as they relate to the natural history of cervical neoplasia.

    We evaluated levels of vaginal extracellular matrix metalloproteinase inducer (EMMPRIN) and matrix metalloproteinase (MMP-8) in vaginal secretions in relation to the composition of vaginal bacterial communities and D- and L-lactic acid levels. The composition of vaginal bacterial communities in 46 women was determined by pyrosequencing the V1 to V3 region of 16S rRNA genes. Lactobacilli were dominant in 71.3% of the women, followed by Gardnerella (17.4%), Streptococcus (8.7%), and Enterococcus (2.2%). Of the lactobacillus-dominated communities, 51.5% were dominated by Lactobacillus crispatus, 36.4% by Lactobacillus iners, and 6.1% each by Lactobacillus gasseri and Lactobacillus jensenii. Concentrations of L-lactic acid were slightly higher in lactobacillus-dominated vaginal samples, but most differences were not statistically significant. D-Lactic acid levels were higher in samples containing L. crispatus than in those with L. iners (Plactic acid in vaginal communities dominated by species of lactobacilli was in concordance with the proportions found in axenic cultures of the various species grown in vitro. Levels of L-lactic acid (Plactic acid to D-lactic acid (P=0.0060), but not concentrations of D-lactic acid, were also correlated with EMMPRIN concentrations. Moreover, vaginal concentrations of EMMPRIN and MMP-8 levels were highly correlated (Plactic acid isomers in the vagina may influence the extent of local EMMPRIN production and subsequent induction of MMP-8. The expression of these proteins may help determine the ability of bacteria to transverse the cervix and initiate upper genital tract infections. A large proportion of preterm births (>50%) result from infections caused by bacteria originating in the vagina, which requires that they traverse the cervix. Factors that influence susceptibility to these infections are not well understood; however, there is evidence that matrix metalloproteinase (MMP-8) is known to alter the integrity of the cervix.

    Full Text Available PURPOSE: To report the antifungal susceptibility profile of yeast isolates obtained from cases of keratitis. METHODS: Susceptibility testing of 15 yeast strains isolated from corneal infections to amphotericin B, fluconazole, itraconazole and ketoconazole was performed using the NCCLS broth microdilution assay. RESULTS: Most episodes of eye infections were caused by Candida albicans. The antifungal drugs tested showed the following minimal inhibitory concentration values against yeast isolates: 0.125-0.5 mg/ml for amphotericin B; 0.125->64.0 mg/ml for fluconazole; 0.015-1.0 mg/ml for itraconazole and 0.015-0.125 mg/ml for ketoconazole. Despite the fact that all Candida isolates were judged to be susceptible to azoles, one isolate showed a minimal inhibitory concentration value significantly higher than a 90% minimal inhibitory concentration of all tested isolates. Rhodotorula rubra was resistant to fluconazole and itraconazole. CONCLUSIONS: Despite the fact that most yeast isolates from corneal infections are usually susceptible to amphotericin B and azoles, they exhibit a wide range of minimal inhibitory concentration values for antifungal drugs. The identification of strains at species level and their susceptibility pattern to antifungal drugs should be considered before determining the concentration to be used in topical antifungal formulations in order to optimize therapeutic response in eye infections.

    Full Text Available Background: C. trachomatis is one of the most important agents of sexually transmitted diseases(STD. Untreated cases of vaginal infection with this bacterium may end up with infertility, scaring andectopic pregnancy. In most cases infection with C. trachomatis is silent (70-80% but when overtinfection occurs the symptoms include: cervicitis, urethritis, and endometritis.Since prevalence of C. trachomatis was not studied in our city, this project was performed to evaluatethe role of this bacterial agent in vaginosis.Material and Methods: Two hundred and two specimens from vaginal discharge of out-patientsreferring to gynecology ward of Ahvaz hospitals were collected and tested for C. trachomatis by PCR.Results: Out of 202 specimens, 33 (16.3% were positive for C. trachomatis.Conclusion: The findings of this study show a high prevalence of C. trachomatis which indicates thatspecial attention must be paid to detection and management of this infection.

    Full Text Available http://api.altmetric.com/v1/ High grade HPV infections and persistence are the strongest risk factors for cervical cancer.Nevertheless other genital microrganism may be involved in the progression of HPV associated lesions. Bacterial vaginosis (BV, an alteration of vaginal flora involving a decrease in Lattobacilli and predominance of anaerobic bacteria, is the most common cause of vaginal complaints for women of childbearing age. Although the specific role of anaerobic bacteria in the pathogenesis of cervical cancer has not been fully elucidated, it has been suggested that HPV infection alone may not be sufficient for full induction of cervical carcinogenesis, and that the simultaneous presence of cervico vaginal bacteria may increase the risk of neoplastic progression. In this cross-sectional study on 356 enrolled outpatients, statistical analyses revealed a significant association of HPV with Ureaplasma urealyticum detection.Although BV was mildly associated with HPV (OR=2.4, it was more common among the HPV positive women. These data confirm that screening for genital infections may be important to reveal the simultaneous presence of different sexually transmitted microrganisms. These results suggest and emphasize the value of the screening for genital infections in HPV positive patients in order to decrease the presence of the other microrganisms and to reduce the probable synergistic effects of coinfections. Prevention is important not only to avoid other sexually transmitted disease and their sequelae, but also to reduce the influence of concomitant microrganisms on HPV infection

    The aim of this study was to evaluate the prevalence of the major microorganisms causing vaginal infections in pregnant women consulting at the Regional Hospital of Sokodé and to assess their sensitivity to antibiotics. This prospective study took place from June 2010 through August 2011 and included 302 pregnant women from whom a sample was taken by a vaginal swab. Samples were processed for parasitic, bacterial, and fungal agents, by microscopic examination and culture. We isolated 273 germs, alone or in association in 221 women. These germs were distributed as follows: Gardnerella vaginalis (55.31%), Candida spp (30.77%), Staphylococcus aureus (5.49%), Enterobacteriaceae (4.40%), Trichomonas vaginalis (3.66%) and Mobiluncus spp (0.37%). No Streptococcus strain was isolated during the study. Over 40% of women had bacterial vaginosis and 23.08% of them were coinfected. The occurrence of coinfection was statistically influenced by the stage of pregnancy (P = 0.05). The susceptibility tests revealed that S. aureus developed a strong resistance to aminopenicillins (66.67%) and cephalosporins (>44.44%), while Enterobacteriaceae was resistant to cephalosporins and quinolones. (16.67%). This study showed that pregnant women in Sokode are still exposed to vaginal infection, caused mostly by G. vaginalis and Candida species. These results underline the need for at least one vaginal swab culture for each woman during pregnancy.

    Though vaginal douching is a common practice among female sex workers that could increase the risk of HIV and adverse reproductive health outcomes, it has drawn limited attention. From November 2010 to January 2011, a convenience sample of female sex workers was recruited in three cities in China. Face-to-face interviews were conducted to gather socio-demographic and behavioural information. Blood samples were collected for syphilis serological tests. Endo-cervical swabs were collected and tested for Neisseria gonorrhoeae and Chlamydia trachomatis by polymerase chain reaction. A logistic regression model was used to determine factors associated with vaginal douching and the association between vaginal douching and sexually transmitted infection. A total of 1032 eligible female sex workers were enrolled. The overall prevalence of any sexually transmitted infection (syphilis, Chlamydia trachomatis or Neisseria gonorrhoeae) and vaginal douching with disinfectant were 23.4% and 23.1%, respectively. Factors independently associated with douching practice included study sites, venue types, ethnicity, having regular partner and sexually transmitted infection history. No significant association was found between vaginal douching and current sexually transmitted infection. Vaginal douching with disinfectant after sex with clients seemed to be a prevalent practice among female sex workers in China. Prevention programmes targeting female sex workers should incorporate components about the adverse health outcomes associated with vaginal douching. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Evidence suggests that specific vaginal bacteria associated with bacterial vaginosis (BV) may increase the risk of adverse health outcomes in women. Among women participating in a randomized, double-blinded trial, we assessed the effect of periodic presumptive treatment (PPT) on detection of select vaginal bacteria. High-risk women from the United States and Kenya with a recent vaginal infection received intravaginal metronidazole 750 mg plus miconazole 200 mg or placebo for 5 consecutive nights each month for 12 months. Vaginal fluid specimens were collected via polyester/polyethylene terephthalate swabs every other month and tested for bacteria, using quantitative polymerase chain reaction (PCR) assays targeting the 16S ribosomal RNA gene. The effect of PPT on bacterium detection was assessed among all participants and stratified by country. Of 234 women enrolled, 221 had specimens available for analysis. The proportion of follow-up visits with detectable quantities was lower in the PPT arm versus the placebo arm for the following bacteria: BVAB1, BVAB2, Atopobium vaginae, Leptotrichia/Sneathia, and Megasphaera. The magnitude of reductions was greater among Kenyan participants as compared to US participants. Use of monthly PPT for 1 year reduced colonization with several bacteria strongly associated with BV. The role of PPT to improve vaginal health should be considered, and efforts to improve the impact of PPT regimens are warranted.

    The prevalence of Trichomonas vaginalis infection is highest in women with intermediate Nugent scores. We hypothesized that the vaginal microbiota in T. vaginalis-infected women differs from that in T. vaginalis-uninfected women. Vaginal samples from 30 T. vaginalis-infected women were matched by Nugent score to those from 30 T. vaginalis-uninfected women. Equal numbers of women with Nugent scores categorized as normal, intermediate, and bacterial vaginosis were included. The vaginal microbiota was assessed using 454 pyrosequencing analysis of polymerase chain reaction-amplified 16S ribosomal RNA gene sequences. The 16S ribosomal RNA gene sequence of an unknown organism was obtained by universal bacterial polymerase chain reaction amplification, cloning, and sequencing. Principal coordinates analysis of the pyrosequencing data showed divergence of the vaginal microbiota in T. vaginalis-infected and T. vaginalis-uninfected patients among women with normal and those with intermediate Nugent scores but not among women with bacterial vaginosis. Cluster analysis revealed 2 unique groups of T. vaginalis-infected women. One had high abundance of Mycoplasma hominis and other had high abundance of an unknown Mycoplasma species. Women in the former group had clinical evidence of enhanced vaginal inflammation. T. vaginalis may alter the vaginal microbiota in a manner that is favorable to its survival and/or transmissibility. An unknown Mycoplasma species plays a role in some of these transformations. In other cases, these changes may result in a heightened host inflammatory response.

    MucoCept is a biotherapeutic for prevention of HIV-1 infection in women and contains a human, vaginal Lactobacillus jensenii that has been genetically enhanced to express the HIV-1 entry inhibitor, modified cyanovirin-N (mCV-N). The objective of this study was to develop a solid vaginal dosage form that supports sustained vaginal colonization of the MucoCept Lactobacillus at levels previously shown, with freshly prepared cultures, to protect macaques from SHIV infection and to test this formulation in a macaque vaginal colonization model. Vaginally disintegrating tablets were prepared by lyophilizing the formulated bacteria in tablet-shaped molds, then packaging in foil pouches with desiccant. Disintegration time, potency and stability of the tablets were assessed. For colonization, non-synchronized macaques were dosed vaginally with either one tablet or five tablets delivered over five days. Vaginal samples were obtained at three, 14, and 21 days post-dosing and cultured to determine Lactobacillus colonization levels. To confirm identity of the MucoCept Lactobacillus strain, genomic DNA was extracted from samples on days 14 and 21 and a strain-specific PCR was performed. Supernatants from bacteria were tested for the presence of the mCV-N protein by Western blot. The tablets were easy to handle, disintegrated within two minutes, potent (5.7x1011 CFU/g), and stable at 4°C and 25°C. Vaginal administration of the tablets to macaques resulted in colonization of the MucoCept Lactobacillus in 66% of macaques at 14 days post-dosing and 83% after 21 days. There was no significant difference in colonization levels for the one or five tablet dosing regimens (p=0.88 Day 14, p=0.99 Day 21). Strain-specific PCR confirmed the presence of the bacteria even in culture-negative macaques. Finally, the presence of mCV-N protein was confirmed by Western blot analysis using a specific anti-mCV-N antibody.

    Vaginal foreign bodies in children usually present with foul-smelling discharge and/or vaginal bleeding. Rarely, these basic clinical diagnostic signs are not present. We report on a 5(1/2)-year-old girl with recurrent lower urinary tract infection as the sole presentation of multiple vaginal foreign bodies. Ultrasound of the lower urinary tract was inconclusive, and cystography indicated for recurrent urinary tract infections was declined by the patient in an outpatient setting. Cystography under general anesthesia raised the suspicion of foreign vaginal objects, and the definitive diagnosis was made by vaginoscopy. The relevant literature covering this subject is reviewed. High level of suspicion and strict basic diagnostic protocol are the most important steps for a timely diagnosis of this condition.

    Bacterial vaginosis is a common vaginal infection characterized by changes in the vaginal microbiota. The objective of this work was to evaluate the colonization ability and curative effect of Lactobacillus fermentum L23 after vaginal administration in female BALB/c mice infected with Gardnerella vaginalis. One dose of Lact. fermentum L23 containing 10(9 ) CFU ml(-1) was administered locally in a murine vaginal model. L23 colonized the vaginal tract of BALB-c mice after one inoculation. The infection by G. vaginalis in a murine model was induced by vaginal administration of a 1 × 10(6 ) CFU ml(-1) suspension. Infection with the pathogen was observed in the vaginal tract for 4 days. At 144 h after inoculation, levels of 4 log10 CFU ml(-1) were observed. The curative effect of L23 was evaluated with one administration at 1 × 10(9 ) CFU ml(-1) 72 h after the inoculation with G. vaginalis. Lactobacillus fermentum L23 inhibited the growth of G. vaginalis. The results of suppression of G. vaginalis using different concentrations of L23 were favourable due that these concentrations are normally used in commercial formulas. The obtained results indicate that Lact. fermentum L23 inhibited the growth of G. vaginalis. Therefore, L23 might be used as a potential biotherapeutic agent for the elimination of this bacterium. The use of the probiotic strain Lactobacillus fermentum L23 as a biotherapeutic agent can be expected to prevent and treat genital infections, particularly recurrent bacterial vaginosis, with similar concentrations to those normally used in commercial formulas. It is likely that the use of this probiotic strain for the treatment of bacterial vaginosis will provide a natural and nontoxic treatment modality. © 2014 The Society for Applied Microbiology.

    2014-01-01

    In a small praxis/ambulance study we evaluated data of 200 women with chronical recurrent cervical infections and with a cervix dysplasia (CIN 1, CIN 2). who got after the primary therapy a treatment with vitamin D vaginal suppositories (12.500 IU, 3 nights a week, for 6 weeks). We found that - when compared with the lactobacillus vaginal suppositories - the high dose vitamin D vaginal treatment might be more effective. Vitamin D showed very good anti-inflammatory effects. In the survey after six weeks therapy 79% of the women had "less vaginal problems," "less discharge" and "less problems with the sexual intercourse." Objectively after six weeks therapy only 7% of the patients still had bacterial and/or fungal vaginal infections that required a treatment. We found that vitamin D is reabsorbed by the vaginal mucosa, but the reabsorption may be individually very different. In the CIN 1 group we found six weeks after treatment good antidysplastic effects, in the CIN 2 group we often found no or only temporary antidysplastic effects. So this vaginal vitamin D treatment method might be an option for the therapy and prevention of chronical cervical infections and maybe of a cervic dysplasia CIN 1 (good antiinflammatory effects, antidysplastic effects). This small study is not representative. We need much bigger studies with much more dates and with a longer follow up. Caution: At the moment we do not know, if the vaginal vitamin D treatment with 12500 IE is possible in pregnancy. We have no experience. Therefore we recommend an effective contraception during the application.

Methods The in vitro anti-viral effect of vaginal and non-vaginal lactobacillus was evaluated using single cycle HIV-1 replication and HSV-2 plaque reduction assays. The XTT proliferation assay was used to monitor the cellular toxicity. The in vivo anti-HSV-1 activity was evaluated in BALB/c mouse model by monitoring skin lesion and immune response development. Results and major conclusion DMEM culture supernatant of L. Gasseri and L. fermentum (PH 7.3 did not show toxic effect but inhibited 50% of HIV replication at 12 and 31% concentrations, respectively. Co-culture of L. gasseri (1000 CFU/ target cell showed mild cytotoxicity but inhibited 68% of HIV replication. The supernatant of L. crispatus inhibited 50% of HSV replication at 4% and also co-culture of L. gasseri, L. rhamnosus and L. crispatus revokes almost all of the HSV multiplication. Culture supernatants of L. gasseri and L. crispatus had significant virucidal effect against the HIV and HSV and inhibited HSV infection in a stage before viral entry to the target cells. Alive L. gasseri cells showed high potential for inhibiting HSV-1 infection in vivo condition. Current data indicates that lactobacilli supernatant encompasses components with neutralizing activity against HIV and HSV and it would be a determinant factor for viral diseases transmission and promising lead for anti-viral probiotic design.

    The natural history of genital Chlamydia trachomatis infections can vary widely; infections can spontaneously resolve but can also last from months to years, potentially progressing to cause significant pathology. The host and bacterial factors underlying this wide variation are not completely understood, but emphasize the bacterium's capacity to evade/adapt to the genital immune response, and/or exploit local environmental conditions to survive this immune response. IFNγ is considered to be a primary host protective cytokine against endocervical C. trachomatis infections. IFNγ acts by inducing the host enzyme indoleamine 2,3-dioxgenase, which catabolizes tryptophan, thereby depriving the bacterium of this essential amino acid. In vitro studies have revealed that tryptophan deprivation causes Chlamydia to enter a viable but non-infectious growth pattern that is termed a persistent growth form, characterized by a unique morphology and gene expression pattern. Provision of tryptophan can reactivate the bacterium to the normal developmental cycle. There is a significant difference in the capacity of ocular and genital C. trachomatis serovars to counter tryptophan deprivation. The latter uniquely encode a functional tryptophan synthase to synthesize tryptophan via indole salvage, should indole be available in the infection microenvironment. In vitro studies have confirmed the capacity of indole to mitigate the effects of IFNγ; it has been suggested that a perturbed vaginal microbiome may provide a source of indole in vivo. Consistent with this hypothesis, the microbiome associated with bacterial vaginosis includes species that encode a tryptophanase to produce indole. In this review, we discuss the natural history of genital chlamydial infections, morphological and molecular changes imposed by IFNγ on Chlamydia, and finally, the microenvironmental conditions associated with vaginal co-infections that can ameliorate the effects of IFNγ on C. trachomatis.

    Effect of Zataria multiflora on bacterial vaginosis and Trichomonas vaginalis is shown in vivo and in vitro. We compare the effectiveness of Zataria multiflora cream and oral metronidazole pill on results of treatment for vaginal infections including Trichomonas and bacterial vaginosis; these infections occur simultaneously. The study included 420 women with bacterial vaginosis, Trichomonas vaginalis, or both infections together, who were randomly divided into six groups. Criteria for diagnosis were wet smear and Gram stain. Vaginal Zataria multiflora cream and placebo pill were administered to the experiment groups; the control group received oral metronidazole pill and vaginal placebo cream. Comparison of the clinical symptoms showed no significant difference in all three vaginitis groups receiving metronidazole pill and vaginal Zataria multiflora cream. However, comparison of the wet smear test results was significant in patients with trichomoniasis and bacterial vaginosis associated with trichomoniasis in the two treatment groups (p = 0.001 and p = 0.01). Vaginal Zataria multiflora cream had the same effect of oral metronidazole tablets in improving clinical symptoms of all three vaginitis groups, as well as the treatment for bacterial vaginosis. It can be used as a drug for treatment of bacterial vaginosis and elimination of clinical symptoms of Trichomonas vaginitis. PMID:26266260

    Full Text Available In the majority of cases, human immunodeficiency virus type 1 (HIV-1 infection is transmitted through sexual intercourse. A single founder virus in the blood of the newly infected donor emerges from a genetic bottleneck, while in rarer instances multiple viruses are responsible for systemic infection. We sought to characterize the sequence diversity at early infection, between two distinct anatomical sites; the female reproductive tract vs. systemic compartment. We recruited 72 women from Uganda and Zimbabwe within seven months of HIV-1 infection. Using next generation deep sequencing, we analyzed the total genetic diversity within the C2-V3-C3 envelope region of HIV-1 isolated from the female genital tract at early infection and compared this to the diversity of HIV-1 in plasma. We then compared intra-patient viral diversity in matched cervical and blood samples with three or seven months post infection. Genetic analysis of the C2-V3-C3 region of HIV-1 env revealed that early HIV-1 isolates within blood displayed a more homogeneous genotype (mean 1.67 clones, range 1-5 clones than clones in the female genital tract (mean 5.7 clones, range 3-10 clones (p<0.0001. The higher env diversity observed within the genital tract compared to plasma was independent of HIV-1 subtype (A, C and D. Our analysis of early mucosal infections in women revealed high HIV-1 diversity in the vaginal tract but few transmitted clones in the blood. These novel in vivo finding suggest a possible mucosal sieve effect, leading to the establishment of a homogenous systemic infection.

    Trichomonas vaginalis infection is the most prevalent nonviral sexually transmitted disease (STD) in the world. A PCR test using vaginal swab samples for the detection of T. vaginalis was developed to add T. vaginalis infection to the growing list of STDs that can be detected by DNA amplification techniques. A primer set, BTUB 9/2, was designed to target a well-conserved region in the beta-tubulin genes of T. vaginalis. All strains (15 of 15) of T. vaginalis tested were successfully detected by PCR giving a single predicted product of 112 bp in gel electrophoresis. No such targeted product was amplified with DNA from Trichomonas tenax, Trichomonas gallinae, Chlamydia trachomatis, Neisseria gonorrhoeae, Giardia lamblia, Chilomastix sulcatus, Dientamoeba fragilis, and Entamoeba histolytica. An optimal analytical sensitivity of one T. vaginalis organism per PCR was achieved. Culture, performed with the Inpouch TV culture system, was examined daily with a light microscope to identify T. vaginalis. Twenty-three of 350 (6.6%) vaginal swab samples from women attending an army medical clinic were culture positive for T. vaginalis. Of these culture positive specimens, PCR detected 22 of 23 (96%) with primer set BTUB 9/2, and wet preparation detected only 12 of 23 (52%). Seventeen specimens were BTUB 9/2-PCR positive and culture negative. Ten of these discordant specimens were determined to be as true positive by PCR using primer sets TVA 5-1/6 and/or AP65 A/B, which target different regions in the T. vaginalis genome, and seven were determined to be false positive. The sensitivity of BTUB 9/2-PCR was 97% and the specificity was 98%. The sensitivities of culture and wet preparation were 70 and 36%, respectively. The diagnosis of T. vaginalis infection by PCR is a sensitive and specific method that could be incorporated into a joint strategy for the screening of multiple STDs by using molecular amplification methods.

    Isolated distal vaginal agenesis is a rare anomaly and mostly becomes symptomatic after menarche. We describe an unusual presentation of this anomaly in a prepubertal girl. An 11-year-old prepubertal girl presented with recurrent urinary tract infection, pyuria, and right-sided renal agenesis. The findings of perineal inspection, ultrasonography, and magnetic resonance imaging were consistent with a distal vaginal agenesis with pyometrocolpos. Discharging pyometrocolpos with dissection of the atretic portion and a pull-through vaginoplasty were performed. A cystoscopy showed no sign of a vesicovaginal or uterine fistula. This rare presentation of distal vaginal agenesis reminds us that congenital malformations of the female genital tract should be considered in patients with congenital anomalies of the urinary system and/or recurrent urinary tract infection, even during the prepubertal period.

    The vaginal microbiota of healthy women consists typically of a diversity of anaerobic and aerobic microorganisms. Lactobacilli are the most prevalent and often numerically dominant microorganisms and are relevant as a barrier to infection. The capacity of lactobacilli to adhere and compete for adhesion sites in the vaginal epithelium and the capacity to produce antimicrobial compounds (hydrogen peroxide, lactic acid, bacteriocin-like substances), are important in the impairment of colonization by pathogens. This review summarizes the role of lactic acid bacteria in preventing illness of the host, including bacterial vaginosis, yeast vaginitis, urinary tract infection and sexually transmitted diseases. The administration of probiotics that colonize the vaginal tract can be important in maintaining a normal urogenital health and also to prevent or treat infections.

    Herpes simplex virus type 2 (HSV-2) infects human genital mucosa and establishes life-long latent infection. It is unmet need to establish a human cell-based microphysiological system for virus biology and anti-viral drug discovery. One of barriers is lacking of culture system of normal epithelial cells in vitro over decades. In this study, we established human normal vaginal epithelial cell (HNVEC) culture using co-culture system. HNVEC cells were then propagated rapidly and stably in a defined culture condition. HNVEC cells exhibited a normal diploid karyotype and formed the well-defined and polarized spheres in matrigel three-dimension (3D) culture, while malignant cells (HeLa) formed disorganized and nonpolar solid spheres. HNVEC cells had a normal cellular response to DNA damage and had no transforming property using soft agar assays. HNVEC expressed epithelial marker cytokeratin 14 (CK14) and p63, but not cytokeratin 18 (CK18). Next, we reconstructed HNVEC-derived 3D vaginal epithelium using air-liquid interface (ALI) culture. This 3D vaginal epithelium has the basal and apical layers with expression of epithelial markers as its originated human vaginal tissue. Finally, we established an HSV-2 infection model based on the reconstructed 3D vaginal epithelium. After inoculation of HSV-2 (G strain) at apical layer of the reconstructed 3D vaginal epithelium, we observed obvious pathological effects gradually spreading from the apical layer to basal layer with expression of a viral protein. Thus, we established an ex vivo 2D and 3D HSV-2 infection model that can be used for HSV-2 virology and anti-viral drug discovery.

    To measure prevalence and risk factors for cervical infections among a large sample of women consulting for vaginal discharge in west Africa and to evaluate its syndromic management through a two visit algorithm. In 11 health centres in Bénin, Burkina Faso, Ghana, Guinée, and Mali 726 women who presented with a vaginal discharge without abdominal pain and who denied being a sex worker (SW) were enrolled. Cervical samples were tested for the detection of Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) with polymerase chain reaction (PCR) assays. All participants were treated with single dose (2 g) metronidazole and clotrimazole cream for 3 days. They were randomised to be told either to come back on day 7 only if there was no improvement in the discharge (group A), or to come back on day 7 regardless of response to treatment (group B). Overall, the prevalence of NG and CT was only 1.9% (14/726) and 3.2% (23/726) respectively. Risk factors previously recommended by the WHO were not associated with the presence of cervical infection, with the exception of the number of sex partners in the past 3 months. When taken together, these risk factors had a positive predictive value of only 6.4% to identify cervical infections. Prevalence of cervical infection was not higher in women who came back on day 7, regardless of the strategy used. Prevalence of NG/CT was lower in Ghana and Bénin (5/280, 1.8%), where comprehensive interventions for SW have been ongoing for years, than in the three other countries (27/446, 6.1%, p = 0.01). NG and CT infections are uncommon in west African women who consult for vaginal discharge and who are not SW. Syndromic management of vaginal discharge should focus on the proper management of vaginitis. The control of gonococcal and chlamydial infection should be redesigned around interventions focusing on sex workers.

    Full Text Available Sexually transmitted infections (STIs such as herpes simplex virus (HSV-2 are associated with an increased risk of HIV infection. Human papillomavirus (HPV is a common STI, but little is know about its role in HIV transmission. The objective of this study was to determine whether cervico-vaginal HPV infection increases the risk of HIV acquisition in women independent of other common STIs.This prospective cohort study followed 2040 HIV-negative Zimbabwean women (average age 27 years, range 18-49 years for a median of 21 months. Participants were tested quarterly for 29 HPV types (with L1 PCR primers and HIV (antibody testing on blood samples with DNA or RNA PCR confirmation. HIV incidence was 2.7 per 100 woman-years. Baseline HPV prevalence was 24.5%, and the most prevalent HPV types were 58 (5.0%, 16 (4.7%, 70 (2.4%, and 18 (2.3%. In separate regression models adjusting for baseline variables (including age, high risk partner, positive test for STIs, positive HSV-2 serology and condom use, HIV acquisition was associated with having baseline prevalent infection with HPV 58 (aHR 2.13; 95% CI 1.09-4.15 or HPV 70 (aHR 2.68; 95% CI 1.08-6.66. In separate regression models adjusting for both baseline variables and time-dependent variables (including HSV-2 status, incident STIs, new sexual partner and condom use, HIV acquisition was associated with concurrent infection with any non-oncogenic HPV type (aHR 1.70; 95% CI 1.02-2.85, any oncogenic HPV type (aHR 1.96; 95% CI 1.16-3.30, HPV 31 (aHR 4.25; 95% CI 1.81-9.97 or HPV 70 (aHR 3.30; 95% CI 1.50-7.20.

    2014-01-01

    Full Text Available Human Immunodeficiency Virus (HIV is a retrovirus that can result in rare opportunistic infections occurring in humans. The onset of these infections is known as Acquired Immune Deficiency Syndrome (AIDS. Sexual transmission is responsible for the majority of infections 1, resulting in transmission of HIV due to infected semen or vaginal and cervical secretions containing infected lymphocytes. HIV microbicides are formulations of chemical or biological agents that can be applied to the vagina or rectum with the intention of reducing the acquisition of HIV. Tenofovir is an NRTI that is phosphorylated by adenylate kinase to tenofovir diphosphate, which in turn competes with deoxyadeosine 5′-triphosphate for incorporation into newly synthesized HIV DNA. Once incorporated, tenofovir diphosphate results in chain termination, thus inhibiting viral replication. Tenofovir has been formulated into a range of vaginal formulations, such as rings, tablets gels and films. It has been shown to safe and effective in numerous animal models, while demonstrating safety and acceptability in numerous human trials. The most encouraging results came from the CAPRISA 004 clinical trial which demonstrated that a 1% Tenofovir vaginal gel reduced HIV infection by approximately 39%.

    The vaginal microbiota plays a significant role in health and disease of the female reproductive tract. Next-generation sequencing techniques based upon the analysis of bacterial 16S rRNA genes permit in-depth study of vaginal microbial community structure to a level of detail not possible with standard culture-based microbiological techniques. The human papillomavirus (HPV) causes both cervical intraepithelial neoplasia (CIN) and cervical cancer. Although the virus is highly prevalent, only a small number of women have a persistent HPV infection and subsequently develop clinically significant disease. There is emerging evidence which leads us to conclude that increased diversity of vaginal microbiota combined with reduced relative abundance of Lactobacillus spp. is involved in HPV acquisition and persistence and the development of cervical precancer and cancer. In this review, we summarise the current literature and discuss potential mechanisms for the involvement of vaginal microbiota in the evolution of CIN and cervical cancer. The concept of manipulation of vaginal bacterial communities using pre- and probiotics is also discussed as an exciting prospect for the field of cervical pathology.

    Chlamydia trachomatis infection is one of the most prevalent bacterial STIs in the USA and worldwide, and women with C. trachomatis infection are at increased risk of acquiring HIV. Because immune activation at the genital mucosa facilitates HIV/SIV infection, C. trachomatis-mediated cytokine induction may contribute to increased HIV transmission in asymptomatic women. To begin to elucidate the mechanisms, we longitudinally analyzed profiles of innate immune factors and HIV infectivity in genital secretions from anatomically specific sites in asymptomatic women during C. trachomatis infection and post-antibiotic treatment. We found higher levels of cytokines and chemokines in endocervical secretions than vaginal secretions. Compared with the convalescent state, G-CSF, IL-1α, and RANTES were elevated in endocervical secretions, IFN-γ and TNF-α were elevated in vaginal secretions, and IFNγ, IL-1β, and MIP1-α were elevated in cervicolavage fluid (CVL), before adjustment of multiple comparisons. Elevated endocervical levels of IP-10 and MCP-1 were associated with the use of hormonal contraception in infected women after successful treatment, suggesting the role of hormonal contraception in inflammation independent of STIs. Importantly, soluble factors found in endocervical secretions during infection enhanced HIV infectivity while no difference in HIV infectivity was found with vaginal secretions or CVL during infection or at convalescence. Taken together, the profiles of immune mediators and in vitro HIV infectivity indicate that the endocervical and vaginal mucosa are immunologically distinct. Our results underscore the importance of considering anatomical site and local sampling methodology when measuring mucosal responses, particularly in the presence of C. trachomatis infection.

    We studied prevalence, risk factors and concordance of vaginal and anal HPV infection and L1 seropositivity among female sex workers (FSW) in Amsterdam. In 2016, FSW aged ≥18 years having a sexually transmitted infections (STI) consultation were invited to participate. Participation entailed taking vaginal and anal self-swabs. Demographics and sexual behaviour data were collected. HPV DNA was analysed using the SPF10-PCR-DEIA-LiPA25-system-v1. Serum was tested for HPV L1 antibodies using multiplex serology assays. Determinants of vaginal and anal high risk HPV (hrHPV) infection and L1 seropositivity were assessed with logistic regression analyses. We included 304 FSW; median age was 29 years (IQR 25-37). Vaginal and anal hrHPV prevalence were 46% and 55%, respectively. HrHPV L1 seropositivity was 37%. Vaginal-anal hrHPV concordance was strong, but no significant association between vaginal or anal hrHPV infection and seropositivity was found. Having had anal sexual contact was not associated with anal hrHPV infection (P = 0.119). Vaginal and anal hrHPV prevalence is high among FSW in Amsterdam, the Netherlands. Promotion of HPV vaccination, preferably at the beginning of the sex (work) career, may be a useful prevention method against hrHPV infection and disease.

    Full Text Available Mucous-penetrating nanoparticles consisting of poly lactic acid-co-glycolic acid (PLGA-polyethylene glycol (PEG could improve targeting of microbicidal drugs for sexually transmitted diseases by intravaginal inoculation. Nanoparticles can induce inflammatory responses, which may exacerbate the inflammation that occurs in the vaginal tracts of women with yeast infections. This study evaluated the effects of these drug-delivery nanoparticles on VK2(E6/E7 vaginal epithelial cell proinflammatory responses to Candida albicans yeast infections. Vaginal epithelial cell monolayers were infected with C. albicans and exposed to 100 μg/ml 49.5 nm PLGA-PEG nanospheres or 20 μg/ml 1.1 x 500 nm PEG-functionalized graphene oxide (GO-PEG sheets. The cells were assessed for changes in mRNA and protein expression of inflammation-related genes by RT-qPCR and physiological markers of cell stress using high content analysis and flow cytometry. C. albicans exposure suppressed apoptotic gene expression, but induced oxidative stress in the cells. The nanomaterials induced cytotoxicity and programmed cell death responses alone and with C. albicans. PLGA-PEG nanoparticles induced mRNA expression of apoptosis-related genes and induced poly (ADP-ribose polymerase (PARP cleavage, increased BAX/BCL2 ratios, and chromatin condensation indicative of apoptosis. They also induced autophagy, endoplasmic reticulum stress, and DNA damage. They caused the cells to excrete inflammatory recruitment molecules chemokine (C-X-C motif ligand 1 (CXCL1, interleukin-1α (IL1A, interleukin-1β (IL1B, calprotectin (S100A8, and tumor necrosis factor α (TNF. GO-PEG nanoparticles induced expression of necrosis-related genes and cytotoxicity. They reduced autophagy and endoplasmic reticulum stress, and apoptotic gene expression responses. The results show that stealth nanoparticle drug-delivery vehicles may cause intracellular damage to vaginal epithelial cells by several mechanisms and that

    Vaginal douching is a common practice and has been hypothesised to increase a woman's risk for human of contracting HIV and sexually transmitted infections (STIs). Our objective was to assess the prevalence of douching and its association with STIs, genital symptoms and HIV/STI knowledge among female sex workers (FSWs). We conducted a cross-sectional study of 837 FSWs with interviews and laboratory tests for HIV/STIs in a prefecture of Yunnan Province in southern China. Vaginal douching was reported by 84% of the women. We found a higher prevalence of vaginal douching practice among FSWs of Han ethnicity, and who were single or cohabitating. Douching was also significantly more common among more educated FSWs and those with greater knowledge of HIV/STIs, and as well as in FSWs who had experienced clinical symptoms in the previous 12 months. Douching was linked to higher risks of HIV (adjusted odds ratio = 2.29; 95% confidence interval 1.01-5.23) and herpes simplex virus type 2 infections (adjusted odds ratio = 2.18; 95% confidence interval 1.46-3.24) after adjusting for confounding factors. Medical professionals and public health workers should correct women's misconception about the effectiveness of douching and discourage women from douching through educational activities. More prospective studies among FSWs are urgently required to identify the relationship between vaginal douching and HIV/STIs. © The Author(s) 2015.

    Vaginal intraepithelial neoplasia (VAIN) is a pre-malignant lesion, potentially leading to vaginal cancer. It is a rare disease, representing less than 1% of all intraepithelial neoplasia of the female genital tract. Similar to cervical intraepithelial neoplasia (CIN), there are three different grades of VAIN. VAIN 1 is also known as a low-grade squamous intraepithelial lesion (LSIL), whereas VAIN 2 and VAIN 3 both represent high-grade squamous intraepithelial lesions (HSIL). Risk factors for the development of VAIN are similar to those for cervical neoplasia, i.e. promiscuity, starting sexual activity at an early age, tobacco consumption and infection with human papillomavirus (HPV). However, compared to other intraepithelial neoplasia such as CIN or VIN (vulvar intraepithelial neoplasia), there still is little understanding about the natural course of VAIN and its capacity for pro- or regression. Furthermore, there is controversial data about the HPV detection rate in VAIN lesions. 67 patients with histologically confirmed VAIN, who were diagnosed between 2003 and 2011 at the University Women´s Hospital of Heidelberg Germany, were included in this study. The biopsies of all participating patients were subjected to HPV genotyping. GP-E6/E7 Nested Multiplex PCR (NMPCR) was used to identify and genotype HPV. Eighteen pairs of type-specific nested PCR primers were assessed to detect the following "high-risk" HPV genotypes: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68, as well as the "low-risk" genotypes 6/11, 42, 43 and 44. The data was analyzed with the software SAS (Statistical Analysis System). All 67 cases were eligible for DNA analysis. The median age was 53 years. The largest group with 53% (n = 36) was formed by women, who were first diagnosed with VAIN between the age of 41 to 60 years. 50% (n = 37) of the patients presented a VAIN in the upper 1/3 of the vagina. 58 (87%) were diagnosed with HSIL (VAIN).

    Full Text Available This trial evaluated the safety and effectiveness of 6% cellulose sulfate vaginal gel in preventing male-to-female vaginal transmission of HIV, gonorrhea and chlamydial infection.This Phase III, double-blind, randomized, placebo-controlled trial was conducted between November 2004 and March 2007 in Lagos and Port Harcourt, Nigeria. We enrolled 1644 HIV-antibody negative women at high risk of HIV acquisition. Study participants were randomized 1:1 to cellulose sulfate or placebo and asked to use gel plus a condom for each act of vaginal intercourse over one year of follow-up. The participants were evaluated monthly for HIV, gonorrhea and chlamydial infection, and for adverse events.The trial was stopped prematurely after the data safety monitoring board of a parallel trial concluded that cellulose sulfate might be increasing the risk of HIV. In contrast, we observed fewer infections in the active arm (10 than on placebo (13, a difference that was nonetheless not statistically significant (HR = 0.8, 95% CI 0.3-1.8; p = 0.56. Rates of gonorrhea and chlamydial infection were lower in the CS group but the difference was likewise not statistically significant (HR = 0.8, 95% CI 0.5-1.1; p = 0.19 for the combined STI outcome. Rates of adverse events were similar across study arms. No serious adverse events related to cellulose sulfate use were reported.Cellulose sulfate gel appeared to be safe in the evaluated study population but we found insufficient evidence that it prevented male-to-female vaginal transmission of HIV, gonorrhea or chlamydial infection. The early closure of the trial compromised the ability to draw definitive conclusions about the effectiveness of cellulose sulfate against HIV.ClinicalTrials.gov NCT00120770.

    To identify the etiologic agents of cervicovaginal infection in order to establish an accurate diagnosis and proper treatment. From January 1995 to December 1999, bacteriological studies were done in cervical discharge specimens from 6,811 patients aged 13 to 65 years, seen at Hospital Juarez in Mexico City. All patients had leucorrhea, pruritus, hyperemia, and abdominal pain. Statistical significance was assessed using the chi-squared test. The frequencies of infectious agents were as follows: G. vaginalis, 22.65%, Candida spp, 19.13%, C, albicans, 7.8%, T. vaginalis, 1.5%, Streptococcus group D, 11.78%, Streptococcus beta hemolytic, 4.59%, E. coli, 13.46%, and Klebsiella spp, 2.0%. Less frequent enterobacteria were: Citrobacter spp, Enterobacter spp, Pseudomonas spp, M. morganii, and P. mirabilis. Almost 3% of patients presented anaerobic species, which were always associated with G. vaginalis. Neisseria spp and N. weaveri were isolated in 0.15% each; N. gonorrhoeae was not isolated in any of the patients. Comparative data showed that Streptococcus beta hemolytic and E. coli increased markedly in the past two years (p < 0.001 for the latter). The diversity of etiologic agents requires performing bacteriological cultures of cervical and vaginal discharge to all symptomatic patients.

    The aims of study were to examine the antibacterial potential of two commercial essential oils (EOs) from coriander (Coriandrum sativum L.) and thyme (Thymus vulgaris L.) against vaginal clinical strains of bacteria and yeast and their chemical composition. Antimicrobial activities of commercial essential oils were determined using macro-diffusion (disc, well) and micro-dilution method in 96-well micro plates against twelve clinical strains of bacteria: Escherichia coli, Proteus mirabilis, Staphylococcus aureus and Enterococcus sp., Staph. aureus ATCC 25923, ATCC 6538 and E. coli 25922 and two clinical Candida albicans strains, including ATTC 10231. Spectrophotometric method was used for determination on C. albicans growth. An antimicrobial effect of EOs was strain specific. Bactericidal activity was higher for coriander EO (minimal inhibitory concentration (MICs) 0·4-45·4 μl ml(-1)) against almost all tested bacteria, except multiple resistant strains of Eneterococcus sp. and Proteus sp. Thyme EO showed slightly better fungicidal activity reaching MIC at 0·11 mg ml(-1) for all C. albicans strains. The effect of EOs on biofilm-forming ability was tested for two strains of Staph. aureus and E. coli, as well as on C. albicans filamentation ability. Brine shrimp lethality bioassay revealed thymus oil total toxicity and coriander oil intoxicity (LC50 = 2·25 mg ml(-1)). The chemical composition of oils was analysed by gas chromatography mass spectrometry showing oxygenated monoterepenes as dominant constituents. The results provide in-vitro scientific support for the safety possible use of Coriander EO against E. coli, Staph. aureus and C. albicans vaginal infections in alternative gynaecological treatment.

    Full Text Available Peritonitis and exit-site infections are important complications in peritoneal dialysis (PD patients that are occasionally caused by opportunistic fungi inhabiting distant body sites. In this study, the oral yeast colonization of PD patients and the antifungal susceptibility profile of the isolated yeasts were accessed and correlated with fungal infection episodes in the following 4 years. Saliva yeast colonization was accessed in 21 PD patients and 27 healthy controls by growth in CHROMagar-Candida® and 18S rRNA/ITS sequencing. PD patients presented a lower oral yeast prevalence when compared to controls, namely, Candida albicans. Other species were also isolated, Candida glabrata and Candida carpophila. The antifungal susceptibility profiles of these isolates revealed resistance to itraconazole, variable susceptibility to caspofungin, and higher MIC values of posaconazole compared to previous reports. The 4-year longitudinal evaluation of these patients revealed Candida parapsilosis and Candida zeylanoides as PD-related exit-site infectious agents, but no correlation was found with oral yeast colonization. This pilot study suggests that oral yeast colonization may represent a limited risk for fungal infection development in PD patients. Oral yeast isolates presented a variable antifungal susceptibility profile, which may suggest resistance to some second-line drugs, highlighting the importance of antifungal susceptibility assessment in the clinical practice.

    Y chromosome DNA from male epithelial and sperm cells was detected in vaginal samples after unprotected sex in experimental studies. We assessed the strength of this association in an observational setting to examine the utility of Y chromosome DNA as a biomarker of recent sexual behaviors in epidemiological studies. The HPV (human papillomavirus) Infection and Transmission Among Couples Through Heterosexual Activity cohort study enrolled 502 women attending a university or college in Montréal, Canada, and their male partners from 2005 to 2010. Participants completed self-administered questionnaires. We used real-time polymerase chain reaction to test women's baseline vaginal samples for Y chromosome DNA and assessed which sexual behaviors were independent predictors of Y chromosome DNA positivity and quantity with logistic and negative binomial regression. Y chromosome DNA positivity decreased from 77% in women in partnerships reporting vaginal sex 0 to 1 day ago to 13% in women in partnerships reporting last vaginal sex of 15 or more days ago (adjusted odds ratio, 0.09; 95% confidence interval, 0.02-0.36). The mean proportion of exfoliated vaginal sample cells with Y chromosome DNA was much lower for women who reported always using condoms (0.01%) than for women who reported never using condoms (2.07%) (adjusted ratio, 26.8; 95% confidence interval, 8.9-80.5). No association was found with reported oral/digital sex frequency or concurrency of partnerships. Y chromosome DNA quantity is strongly associated with days since last vaginal sex and lack of condom use in observational settings. Y chromosome DNA quantity may prove useful as a correlate of recent vaginal sex in observational studies lacking data on sexual behavior, such as surveillance studies of human papillomavirus infection prevalence.

    HIV synergy with sexually transmitted co-infections is well-documented in the clinic. Co-infection with Neisseria gonorrhoeae in particular, increases genital HIV shedding and mucosal transmission. However, no animal model of co-infection currently exists to directly explore this relationship or to bridge the gap in understanding between clinical and in vitro studies of this interaction. This study aims to test the feasibility of using a humanized mouse model to overcome this barrier. Combining recent in vivo modelling advancements in both HIV and gonococcal research, we developed a co-infection model by engrafting immunodeficient NSG mice with human CD34+ hematopoietic stem cells to generate humanized mice that permit both systemic HIV infection and genital N. gonorrhoeae infection. Systemic plasma and vaginal lavage titres of HIV were measured in order to assess the impact of gonococcal challenge on viral plasma titres and genital shedding. Engrafted mice showed human CD45+ leukocyte repopulation in blood and mucosal tissues. Systemic HIV challenge resulted in 104-105 copies/mL of viral RNA in blood by week 4 post-infection, as well as vaginal shedding of virus. Subsequent gonococcal challenge resulted in unchanged plasma HIV levels but higher viral shedding in the genital tract, which reflects published clinical observations. Thus, human CD34+ stem cell-transplanted NSG mice represent an experimentally tractable animal model in which to study HIV shedding during gonococcal co-infection, allowing dissection of molecular and immunological interactions between these pathogens, and providing a platform to assess future therapeutics aimed at reducing HIV transmission.

    Full Text Available The objective of this trial was to determine the effectiveness of 1.0% C31G (SAVVY in preventing male-to-female vaginal transmission of HIV infection among women at high risk.This was a Phase 3, double-blind, randomized, placebo-controlled trial. Participants made up to 12 monthly follow-up visits for HIV testing, adverse event reporting, and study product supply. The study was conducted between September 2004 and December 2006 in Lagos and Ibadan, Nigeria, where we enrolled 2153 HIV-negative women at high risk of HIV infection. Participants were randomized 1 ratio 1 to SAVVY or placebo. The effectiveness endpoint was incidence of HIV infection as indicated by detection of HIV antibodies in oral mucosal transudate (rapid test or blood (ELISA, and confirmed by Western blot or PCR testing. We observed 33 seroconversions (21 in the SAVVY group, 12 in the placebo group. The Kaplan-Meier estimates of the cumulative probability of HIV infection at 12 months were 0.028 in the SAVVY group and 0.015 in the placebo group (2-sided p-value for the log-rank test of treatment effect 0.121. The point estimate of the hazard ratio was 1.7 for SAVVY versus placebo (95% confidence interval 0.9, 3.5. Because of lower-than-expected HIV incidence, we did not observe the required number of HIV infections (66 for adequate power to detect an effect of SAVVY. Follow-up frequencies of adverse events, reproductive tract adverse events, abnormal pelvic examination findings, chlamydial infections and vaginal infections were similar in the study arms. No serious adverse event was attributable to SAVVY use.SAVVY did not reduce the incidence of HIV infection. Although the hazard ratio was higher in the SAVVY than the placebo group, we cannot conclude that there was a harmful treatment effect of SAVVY.

    Chlamydia trachomatis and Trichomonas vaginalis, two prevalent sexually transmitted infections, are known to increase HIV risk in women and could potentially diminish preexposure prophylaxis efficacy, particularly for topical interventions that rely on local protection. We investigated in macaques whether coinfection with Chlamydia trachomatis/Trichomonas vaginalis reduces protection by vaginal tenofovir (TFV) gel. Vaginal TFV gel dosing previously shown to provide 100 or 74% protection when applied either 30 min or 3 days before simian HIV(SHIV) challenge was assessed in pigtailed macaques coinfected with Chlamydia trachomatis/Trichomonas vaginalis and challenged twice weekly with SHIV162p3 for up to 10 weeks (two menstrual cycles). Three groups of six macaques received either placebo or 1% TFV gel 30 min or 3 days before each SHIV challenge. We additionally assessed TFV and TFV diphosphate concentrations in plasma and vaginal tissues in Chlamydia trachomatis/Trichomonas vaginalis coinfected (n = 4) and uninfected (n = 4) macaques. Chlamydia trachomatis/Trichomonas vaginalis coinfections were maintained during the SHIV challenge period. All macaques that received placebo gel were SHIV infected after a median of seven challenges (one menstrual cycle). In contrast, no infections were observed in macaques treated with TFV gel 30 min before SHIV challenge (P Trichomonas vaginalis coinfected compared with Chlamydia trachomatis/Trichomonas vaginalis uninfected macaques. Our findings in this model suggest that Chlamydia trachomatis/Trichomonas vaginalis coinfection may have little or no impact on the efficacy of highly effective topical TFV modalities and highlight a significant modulation of TFV pharmacokinetics.

    Full Text Available Abstract Background Each year more than two million people are newly infected with HIV worldwide, a majority of them through unprotected vaginal sex. More than half of new infections in adults occur in women. Male condoms and male circumcision reduce the risk of HIV acquisition; but the uptake of these methods is out of the control of women. We therefore aimed to determine the effectiveness of vaginal microbicides (a potential female-controlled method for prevention of sexual acquisition of HIV in women. Methods We conducted a comprehensive search of peer-reviewed and grey literature for publications of randomised controlled trials available by September 2012. We screened search outputs, selected studies, assessed risk of bias, and extracted data in duplicate; resolving differences by discussion and consensus. Results We identified 13 eligible trials that compared vaginal microbicides to placebo. These studies enrolled 35,905 sexually active HIV-negative women between 1996 and 2011; in Benin, Cameroon, Cote d’Ivoire, Ghana, Kenya, Malawi, Nigeria, South Africa, Tanzania, Uganda, Zambia, Zimbabwe, India, Thailand, and the United States of America. A small trial of 889 women found that tenofovir (a nucleotide reverse transcriptase inhibitor significantly reduces the risk of HIV acquisition (risk ratio [RR] 0.63, 95% confidence intervals [CI] 0.43 to 0.93.

    Oropharyngeal candidiasis remains a significant clinical problem in HIV-infected and AIDS patients in regions of Africa where anti-retroviral therapy isn\\'t readily available. In this study we identified the yeast populations associated with oral lesions in HIV-infected patients in Southwest Uganda who were receiving treatment with nystatin and topical clotrimazole. Samples were taken from 605 patients and 316 (52%) of these yielded yeast growth following incubation on Sabouraud dextrose agar. Samples were subsequently re-plated on CHROMagar Candida medium to facilitate identification of the yeast species present. The majority (56%) of culture-positive samples yielded a mix of two or more species. Candida albicans was present in 87% (274\\/316) of patient samples and accounted for 87% (120\\/138) of single species samples. Candida glabrata, Candida tropicalis and Candida norvegensis were also found in cultures that yielded a single species. No Candida dubliniensis isolates were identified in this population.

    Full Text Available The present study was performed to determine the protective role of dietary selenium (Se yeast supplementation in porcine circovirus type 2 (PCV2 infected mice. Forty-eight Kun Ming female mice were randomly assigned to Se yeast group (0.3%Se +basal diet, n = 24 and control group (basal diet, n = 24. After 3 days of adaptive feeding and 15 days treatment with the experimental feed, mice were challenged by intraperitioneal injection of PCV2 at the dosage of 2000 TCID50 (50% tissue culture infection dose, TCID50. Serum total superoxide dismutase (SOD activity, malondialdehyde (MDA level, tumor necrosis factor alpha (TNF-α, C-reactive protein (CRP and interleukin-1 beta (IL-1β levels were measured at 5, 10, 15, 20 days post infection (dpi. The PCV2 virus load in the liver, spleen and lung, and the microscopic lesions in the liver, spleen and lung also were determined on 5, 10, 15, and 20 dpi. Dietary Se yeast supplementation decreased (Pμ0.05 the serum levels of TNF-α, but had no significant effect on the activity of SOD and the levels of MDA, CRP and IL-1β between experimental and control groups. Dietary Se yeast supplementation had little effect on the PCV2 virus load in the liver, spleen and lung. However, mice in the selenium yeast group showed a significant decrease in microscopic lesion scores in the lung and spleen compared with those in the control group (Pμ0.05. These data indicate Se yeast attenuated the PCV2 infection through altering the systemic inflammation and maintaining the normal organ morphology.

    Full Text Available Pregnant women with gestational diabetes mellitus (GDM are reported to be at increased risk for infections of the genital tract. This study aimed to compare the prevalence of asymptomatic bacterial vaginosis (BV and Candida colonization at early gestation between pregnant women with and without diabetic conditions during pregnancy. We included data from 8, 486 singleton pregnancies that underwent an antenatal infection screen-and-treat programme at our department. All women with GDM or pre-existing diabetes were retrospectively assigned to the diabetic group (DIAB, whereas non-diabetic women served as controls (CON. Prevalence for BV and Candida colonization was 9% and 14% in the DIAB group, and 9% and 13% in the CON group, respectively (n.s.. No significant difference regarding stillbirth and preterm delivery (PTD, defined as a delivery earlier than 37 + 0 (37 weeks plus 0 days weeks of gestation was found. We could not find an increased risk of colonization with vaginal pathogens at early gestation in pregnant women with diabetes, compared to non-diabetic women. Large prospective studies are needed to evaluate the long-term risk of colonization with vaginal pathogens during the course of pregnancy in these women.

    Full Text Available Abstract Background: Ureaplasma and M. genitalium species belong to a kind of bacteria that are sexually transmitted and are the possible cause of pelvic inflammatory disease and nongonococcal urethritis, and et al. The aim of this study was to determine the urea plasma and Mycoplasma genitalium species frequency in women with vaginal infection and various sexual partners who referred to women, s health promotion and treatment center in Arak. Materials and Methods: Endocervical swab samples from 110 women with vaginal infections referred to women’s health promotion and treatment center in Arak, were prepared. Patients’ personal information and identities during reception process were registered. The samples were transferred to the laboratory in the transport environment and after DNA extraction, were evaluated according to Real-time PCR assay. Results: Urea plasma and Mycoplasma genitalium bacteria existed in 96(87.27% and 4(3.63% of patients, respectively. Among them, 4 cases had both bacteria infections. The amount of isolation in young women between 30-39 years old was more than others. Conclusion: The results show that the colonization of urea plasma species in adult women is 40-80% and in studied group is 87.27%. These results indicate that with due attention to the increasing number of sexual partners and the increase of sexual activity, the urea plasma colonization of women will increase. In view of the potential influence of mycoplasma species on side effects resulted from pregnancy infection of mothers and mortality, on-time diagnosis and treatment will be increasingly essential.

The specimen also tested positive for Chlamydia trachomatis deoxyribonucleic acid (DNA) by cryptic plasmid and omp1 gene PCR assays. The patient was successfully treated with azithromycin based on the antibiotic susceptibility testing results of U. parvum and M. hominis by microbroth dilution. Since sexually transmitted infections enhance the transmission of HIV, HIV-positive patients should be screened routinely for these pathogens.

    Full Text Available The majority of HIV-1 infections worldwide are acquired via mucosal surfaces. However, unlike the vaginal mucosa, the issue of whether the oral mucosa can act as a portal of entry for HIV-1 infection remains controversial. To address potential differences with regard to the fate of HIV-1 after exposure to oral and vaginal epithelium, we utilized two epithelial cell lines representative of buccal (TR146 and pharyngeal (FaDu sites of the oral cavity and compared them with a cell line derived from vaginal epithelium (A431 in order to determine (i HIV-1 receptor gene and protein expression, (ii whether HIV-1 genome integration into epithelial cells occurs, (iii whether productive viral infection ensues, and (iv whether infectious virus can be transferred to permissive cells. Using flow cytometry to measure captured virus by HIV-1 gp120 protein detection and western blot to detect HIV-1 p24 gag protein, we demonstrate that buccal, pharyngeal and vaginal epithelial cells capture CXCR4- and CCR5-utilising virus, probably via non-canonical receptors. Both oral and vaginal epithelial cells are able to transfer infectious virus to permissive cells either directly through cell-cell attachment or via transcytosis of HIV-1 across epithelial cells. However, HIV-1 integration, as measured by real-time PCR and presence of early gene mRNA transcripts and de novo protein production were not detected in either epithelial cell type. Importantly, both oral and vaginal epithelial cells were able to support integration and productive infection if HIV-1 entered via the endocytic pathway driven by VSV-G. Our data demonstrate that under normal conditions productive HIV-1 infection of epithelial cells leading to progeny virion production is unlikely, but that epithelial cells can act as mediators of systemic viral dissemination through attachment and transfer of HIV-1 to permissive cells.

    The objective was to explore the determinants of menstrual hygienic practices and its effect on Reproductive Tract Infections (RTI) among ever married women in India. District Level Household and Facility Survey-3 (DLHS) India data have been used in the study. The respondents constituted ever married women (N = 577,758) in the age group of 15-49. Bivariate and multivariate techniques were employed using IBM SPSS statistics 20. Individual effects of socio economic, demographic and gynecological factors on menstrual hygienic practices, RTIs and abnormal vaginal discharged respectively were calculated using binary logistic regression. A meager 15% of women used sanitary pad/locally prepared napkins during menstruation in India. Both RTI and Vaginal discharge were positively related with non-use of hygienic methods. The women who used unhygienic method during menstruation were more likely to have any symptom of RTI (OR = 1.046, p vaginal discharge (OR = 1.303, p < 0.001, CI = 1.266-1.341). The reason for the symptoms of RTI may be diverse and not only limited to the unhygienic menstrual practices although this may be one of the reasons causing reproductive morbidity. Awareness, affordability and privacy are some of the major concerns that need immediate attention to promote the use of sanitary pad during the time of menstruation. Establishing relation between menstrual practices and RTI is in its initial stage of investigation and hence needs further research. Copyright © 2015 Elsevier B.V. All rights reserved.

    Epiphytic isolates with yeast characteristics from grapes of the Malbec cultivar were obtained in order to find antagonists against Alternaria alternata. From a total of 111 isolates, 82% corresponded to the yeast-like organism Aureobasidium pullulans and the rest to the non-Saccharomyces yeasts Hanseniaspora uvarum (6.3%), Metschnikowia pulcherrima or spp. (5.4%), Cryptoccocus laurentti II (2.7%), Starmerella bacilaris or Candida zemplinina (2.7%) and Rhodotorula spp. (0.9%). The 22.4% (15 out of 67) of epiphytic yeasts and yeast-like organisms evaluated were able to reduce A. alternata infection from 0.0 to 4.4% when applied 2h previous to pathogen inoculation on wounds of grape berries. From these selected strains, 14 out of 15 strains completely prevented A. alternata infection (0.0%), which implies potential for field application. All Metschnikowia (pulcherrima or spp.), S. bacillaris and almost all H. uvarum evaluated strains showed antagonist capability against A. alternata. Meanwhile, none of the lesser nutritional requirement strains belonging to A. pullulans, Cr. laurenti II and Rhodotorula spp. did. All the yeasts with capacity to prevent A. alternata infection also reduced tenuazonic acid (TA) production by 81.2 to 99.8%, finding TA levels similar to negative controls. Therefore, the epiphytic yeasts selected are promising as biological control agents against Alternaria infection and toxin production in grapes for winemaking. Copyright © 2017 Elsevier B.V.

    Full Text Available Repeated use, coitus-independent microbicide gels that do not contain antiretroviral agents also used as first line HIV therapy are urgently needed to curb HIV spread. Current formulations require high doses (millimolar range of antiretroviral drugs and typically only provide short-term protection in macaques. We used the macaque model to test the efficacy of a novel combination microbicide gel containing zinc acetate and micromolar doses of the novel non-nucleoside reverse transcriptase inhibitor MIV-150 for up to 24 h after repeated gel application.Rhesus macaques were vaginally challenged with SHIV-RT up to 24 h after repeated administration of microbicide versus placebo gels. Infection status was determined by measuring virologic and immunologic parameters. Combination microbicide gels containing 14 mM zinc acetate dihydrate and 50 µM MIV-150 afforded full protection (21 of 21 animals for up to 24 h after 2 weeks of daily application. Partial protection was achieved with the MIV-150 gel (56% of control at 8 h after last application, 11% at 24 h, while the zinc acetate gel afforded more pronounced protection (67% at 8-24 h. Marked protection persisted when the zinc acetate or MIV-150/zinc acetate gels were applied every other day for 4 weeks prior to challenge 24 h after the last gel was administered (11 of 14 protected. More MIV-150 was associated with cervical tissue 8 h after daily dosing of MIV-150/zinc acetate versus MIV-150, while comparable MIV-150 levels were associated with vaginal tissues and at 24 h.A combination MIV-150/zinc acetate gel and a zinc acetate gel provide significant protection against SHIV-RT infection for up to 24 h. This represents a novel advancement, identifying microbicides that do not contain anti-viral agents used to treat HIV infection and which can be used repeatedly and independently of coitus, and underscores the need for future clinical testing of their safety and ability to prevent HIV transmission in

    Seven microorganisms (N. gonorrhoeae, C. albicans, T. vaginalis, G. vaginalis, M. hominis, U. urealyticum and Streptococcus of group B) have been assayed in genital samplings of 164 asymptomatic women (control group) and of 374 women suffering from abnormal vaginal secretions (vaginitis group). All these bacteria except group B Streptococci were isolated in the vaginitis group more frequently than in the control group (p less than 0.01). The proportion of negative cultures for all tested bacteria was 39% in the control group and 6.4% in the vaginitis group (p less than 0.01). This shows an association of these bacteria with 70% of the patients of the vaginitis group and with only 26% of the women of the control group (p less than 0.01). It is to be noted that the pH values are higher in the group of women with vaginitis than in the control group (p less than 0.01). Comparison of the microbial flora during "specific" an "non-specific" vaginitis indicates that G. vaginalis is isolated more frequently in patients with non-specific vaginitis than among those with specific vaginitis (p less than 0.01). Likewise, M. hominis is isolated more frequently in groups of women with either non-specific vaginitis or T. vaginalis vaginitis, than in groups of patients with a C. albicans vaginitis (p less than 0,01). The results of this study indicate that there is a causal relationship between vaginitis and the presence of T. vaginalis. C. albicans, G. vaginalis, M. hominis or N. gonorrhoeae, either as a single or a mixed infection, and that there is a relationship between increased pH values and abnormal vaginal secretions.

    To investigate the effects of vaginal Brucella ovis infection on the reproductive performance of red deer (Cervus elaphus) hinds. To determine whether stags may become infected with B. ovis by venereal transmission from mating infected hinds. Thirty mixed-age red deer hinds serologically negative for B. ovis antibodies were synchronised for oestrus on 22 March 2000. B. ovis was inoculated into the vagina of each hind at oestrus and again, 18 days later. At oestrus, hinds were randomly allocated to six groups, each joined with a 16 month-old red deer stag seronegative for B. ovis, for 55 days. Hinds were blood sampled and scanned for pregnancy using rectal ultrasonography at monthly intervals. Six pregnant and four non-pregnant hinds were slaughtered pre-calving and three hinds were slaughtered post-calving. Reproductive tracts and foetuses were examined grossly, histologically and microbiologically. Calves were identified and blood sampled within 3 days of birth. Hinds and calves were blood sampled in February and May 2001 and vaginal swabs were collected from hinds for B. ovis culture. Blood was collected from stags, 5 and 19 days after mating and semen was collected for B. ovis culture. The 17 remaining hinds were mated in 2001 to two mixed-age wapiti (Cervus canadensis) stags. Both stags were blood sampled after mating. Sera were tested in a B. ovis complement fixation test (CFT) and enzyme-linked immunosorbent assay (ELISA). All 30 hinds developed B. ovis antibody levels, measurable using either the CFT or ELISA, but these did not remain elevated. There was no evidence of infection, either by gross pathology, histopathology or microbiological culture in the ten hinds or six foetuses slaughtered pre-calving. All remaining 20 hinds produced normal calves, 15 of which survived until weaning. Three hinds experienced dystocia and gave birth to dead calves and two calves died within 4 days of birth. One hind which had dystocia was euthanased. Samples from this hind

    Two devices for vaginal self-sampling of dry cell material (Evalyn Brush, Rovers Medical Devices; Qvintip, Aprovix) were compared using the Abbott RealTime High Risk HPV test. Both self-sampling devices (change of order with every patient) including instructions for use and a questionnaire were handed to 146 patients in a colposcopy clinic prior to scheduled colposcopies with collection of cervical reference specimens by gynaecologists using a broom-like device. Matched self-collected and physician collected specimens were transferred to ThinPrep medium and tested for the presence of hr-HPV. Biopsies were taken if indicated by colposcopy. Evaluation of 136 patients with complete data (136/146; 93.2%) showed high agreement of overall hr-HPV detection rates between self-collected and clinician-collected specimens (Evalyn: 91.2% [kappa 0.822]; Qvintip: 89.0% [kappa 0.779]). Colposcopy and histological evaluation revealed 55 women without cervical intraepithelial neoplasia (CIN), 32 CIN1, 34 CIN2, 14 CIN3 and one adenocarcinoma in situ. Hr-HPV testing detected all CIN3+ cases on the clinician-taken or Evalyn self-samples (14/14) and 93% of them on the Qvintip samples (13/14). There was no significant difference regarding the sensitivity for CIN2+ or CIN3+ and specificity of hr-HPV testing on self- vs. clinician samples and on Evalyn vs. Qvintip. Based on signal intensities of β-globin, the observed DNA concentration with Evalyn samples (mean CN: 22.0; 95%-CI: 21.5-22.6) was found to be significantly higher compared to that of Qvintip samples (mean CN: 23.8; 95%-CI 23.2-24.4), regardless of the order of self-sampling (p<0.0001). Most women considered self-sampling easy and comfortable. Qvintip was considered easier than the Evalyn Brush to understand (p<0.001) and to use (p=0.002). This study confirms that hr-HPV testing with a clinically validated PCR-based HPV assay is as accurate on self-samples as on clinician-samples without significant difference between both

    Full Text Available HIV serodiscordant couples represent at least half of all HIV-affected couples worldwide. Many of these couples have childbearing desires. Safer methods of conception may allow for pregnancy while minimizing the risk of sexual transmission of HIV. In serodiscordant partnerships with an HIV-infected female and HIV-uninfected male, vaginal insemination of a partner's semen during the fertile period coupled with 100% condom use may be the safest method of conception.

    Candidiasis in HIV/AIDS patients continues to be a public health problem. Antifungal therapies are not always effective and may result in complications, such as the development of drug-resistant strains of Candida species. This study evaluated the impact of probiotic consumption on Candida colonization of the oral and vaginal mucosa. A pilot study was conducted in 24 women (17 HIV-infected, 7 HIV-uninfected) from the Women's Interagency HIV Study. The women underwent a 60-day initiation period with no probiotic consumption, followed by two 15-day consumption periods, with a different probiotic yogurt (DanActive™ or YoPlus™ yogurt) during each interval. There was a 30-day washout period between the two yogurt consumption periods. Oral and vaginal culture swabs were collected on days 0, 60, 74, and 120. Candida was detected by inoculating each swab in both Sabouraud's dextrose agar with or without chloramphenicol and CHROMagar. Less fungal colonization among women was observed when the women consumed probiotic yogurts (54 % of the women had vaginal fungal colonization during the non-probiotic yogurt consumption period, 29 % during the DanActive™ period, and 38 % during YoPlus™ yogurt consumption period), and HIV-infected women had significantly lower vaginal fungal colonization after they consumed DanActive™ yogurt compared to the non-intervention periods (54 vs 29 %, p = 0.03). These data are promising, but as expected in a small pilot study, there were some significant changes but also some areas where colonization was not changed. This type of conflicting data is supportive of the need for a larger trial to further elucidate the role of probiotic yogurts in fungal growth in HIV-infected women.

    The immunogenicity and the efficacy of a beta-propiolactone-inactivated caprine herpesvirus 1 (CpHV-1) vaccine adjuvanted with MF59™ were tested in goats. Following two subcutaneous immunizations, goats developed high titers of CpHV-1-specific serum and vaginal IgG and high serum virus neutralization (VN) titers. Peripheral blood mononuclear cells (PBMC) stimulated in vitro with inactivated CpHV-1 produced high levels of soluble IFN-gamma and exhibited high frequencies of IFN-gamma producing cells while soluble IL-4 was undetectable. On the other hand, control goats receiving the inactivated CpHV-1 vaccine without adjuvant produced only low serum antibody responses. A vaginal challenge with virulent CpHV-1 was performed in all vaccinated goats and in naïve goats to assess the efficacy of the two vaccines. Vaginal disease was not detected in goats vaccinated with inactivated CpHV-1 plus MF59™ and these animals had undetectable levels of infectious challenge virus in their vaginal washes. Goats vaccinated with inactivated CpHV-1 in the absence of adjuvant exhibited a less severe disease when compared to naïve goats but shed titers of challenge virus that were similar to those of naïve goats. Detection and quantitation of latent CpHV-1 DNA in sacral ganglia in challenged goats revealed that the inactivated CpHV-1 plus MF59™ vaccine was able to significantly reduce the latent viral load when compared either to the naïve goats or to the goats vaccinated with inactivated CpHV-1 in the absence of adjuvant. Thus, a vaccine composed of inactivated CpHV-1 plus MF59™ as adjuvant was strongly immunogenic and induced effective immunity against vaginal CpHV-1 infection in goats. PMID:22511971

    Vaginal reconstruction can be an uncomplicated and straightforward procedure when attention to detail is maintained. The Abbe-McIndoe procedure of lining the neovaginal canal with split-thickness skin grafts has become standard. The use of the inflatable Heyer-Schulte vaginal stent provides comfort to the patient and ease to the surgeon in maintaining approximation of the skin graft. For large vaginal and perineal defects, myocutaneous flaps such as the gracilis island have been extremely useful for correction of radiation-damaged tissue of the perineum or for the reconstruction of large ablative defects. Minimal morbidity and scarring ensue because the donor site can be closed primarily. With all vaginal reconstruction, a compliant patient is a necessity. The patient must wear a vaginal obturator for a minimum of 3 to 6 months postoperatively and is encouraged to use intercourse as an excellent obturator. In general, vaginal reconstruction can be an extremely gratifying procedure for both the functional and emotional well-being of patients.

  10. High risk HPV contamination of endocavity vaginal ultrasound probes: an underestimated route of nosocomial infection?

    Directory of Open Access Journals (Sweden)

    Jean-sebastien Casalegno

    Full Text Available BACKGROUND: Endocavity ultrasound is seen as a harmless procedure and has become a common gynaecological procedure. However without correct disinfection, it may result in nosocomial transmission of genito-urinary pathogens, such as high-risk Human Papillomavirus (HR-HPV. We aimed to evaluate the currently recommended disinfection procedure for covered endocavity ultrasound probes, which consists of "Low Level Disinfection" (LLD with "quaternary ammonium compounds" containing wipes. METHODS: From May to October 2011 swabs were taken from endovaginal ultrasound probes at the Gynecology Department of the Lyon University Hospital. During the first phase (May-June 2011 samples were taken after the ultrasound examination and after the LLD procedure. In a second phase (July-October 2011 swab samples were collected just before the probe was used. All samples were tested for the presence of human DNA (as a marker for a possible transmission of infectious pathogens from the genital tract and HPV DNA with the Genomica DNA microarray (35 different HPV genotypes. RESULTS: We collected 217 samples before and 200 samples after the ultrasound examination. The PCR was inhibited in two cases. Human DNA was detected in 36 (18% post-examination samples and 61 (28% pre-examination samples. After the ultrasound LLD procedure, 6 (3.0% samples contained HR-HPV types (16, 31, 2×53 and 58. Similarly, HPV was detected in 6 pre-examination samples (2.7%. Amongst these 4 (1.9% contained HR-HPV (types 53 and 70. CONCLUSION: Our study reveals that a considerable number of ultrasound probes are contaminated with human and HR-HPV DNA, despite LLD disinfection and probe cover. In all hospitals, where LLD is performed, the endovaginal ultrasound procedure must therefore be considered a source for nosocomial HR-HPV infections. We recommend the stringent use of high-level disinfectants, such as glutaraldehyde or hydrogen peroxide solutions.

    Urinary tract infections are a frequent ailment in patients in intensive care units. Candida and other yeasts cause 5-12% of these infections. The value of the finding of any yeast is controversial, and there is no consensus about which parameters are adequate for differentiating urinary infections from colonization or contamination. To analyse the epidemiological characteristics of patients with funguria, to determine potential cut-off points in cultures (to distinguish an infection from other conditions), to identify the prevalent yeast species, and to determine the value of a second urine sample. A multicentre study was conducted in intensive care units of 14 hospitals in the Buenos Aires City Mycology Network. The first and second samples of urine from every patient were cultured. The presence of white cells and yeasts in direct examination, colony counts, and the identification of the isolated species, were evaluated. Yeasts grew in 12.2% of the samples. There was no statistical correlation between the number of white cells and the fungal colony-forming units. Eighty five percent of the patients had indwelling catheters. Funguria was not prevalent in women or in patients over the age of 65. Candida albicans, followed by Candida tropicalis, were the most frequently isolated yeasts. Candida parapsilosis and Candida glabrata appeared less frequently. The same species were isolated in 70% of second samples, and in 23% of the cases the second culture was negative. It was not possible to determine a useful cut-off point for colony counts to help in the diagnosis of urinary infections. As in other publications, C. albicans, followed by C. tropicalis, were the most prevalent species. Copyright © 2015 Asociación Española de Micología. Published by Elsevier Espana.

  13. Antifungal efficacy during Candida krusei infection in non-conventional models correlates with the yeast in vitro susceptibility profile.

    Directory of Open Access Journals (Sweden)

    Liliana Scorzoni

    Full Text Available The incidence of opportunistic fungal infections has increased in recent decades due to the growing proportion of immunocompromised patients in our society. Candida krusei has been described as a causative agent of disseminated fungal infections in susceptible patients. Although its prevalence remains low among yeast infections (2-5%, its intrinsic resistance to fluconazole makes this yeast important from epidemiologic aspects. Non mammalian organisms are feasible models to study fungal virulence and drug efficacy. In this work we have used the lepidopteran Galleria mellonella and the nematode Caenorhabditis elegans as models to assess antifungal efficacy during infection by C. krusei. This yeast killed G. mellonella at 25, 30 and 37°C and reduced haemocytic density. Infected larvae melanized in a dose-dependent manner. Fluconazole did not protect against C. krusei infection, in contrast to amphotericin B, voriconazole or caspofungin. However, the doses of these antifungals required to obtain larvae protection were always higher during C. krusei infection than during C. albicans infection. Similar results were found in the model host C. elegans. Our work demonstrates that non mammalian models are useful tools to investigate in vivo antifungal efficacy and virulence of C. krusei.

    During colonization of the vaginal tract Candida glabrata cells are challenged with the presence of acetic acid at a low pH, specially when dysbiosis occurs. To avoid exclusion from this niche C. glabrata cells are expected to evolve efficient adaptive responses to cope with this stress; however, these responses remain largely uncharacterized, especially in vaginal strains. In this work a cohort of 18 vaginal strains and 2 laboratory strains (CBS138 and KUE100) were phenotyped for their tolerance against inhibitory concentrations of acetic acid at pH 4. Despite some heterogeneity has been observed among the vaginal strains tested, in general these strains were considerably more tolerant to acetic acid than the laboratory strains. To tackle the mechanistic insights behind this differential level of tolerance observed, a set of vaginal strains differently tolerant to acetic acid (VG281∼VG49 acetic acid the more tolerant vaginal strains exhibited a higher activity of the plasma membrane proton pump CgPma1 and a reduced internal accumulation of the acid, these being two essential features to maximize tolerance. Based on the higher level of resistance exhibited by the vaginal strains against the action of a β-1,3-glucanase, it is hypothesized that the reduced internal accumulation of acetic acid inside these strains may originate from them having a different cell wall structure resulting in a reduced porosity to undissociated acetic acid molecules. Both the vaginal and the two laboratory strains were found to consume acetic acid in the presence of glucose indicating that metabolization of the acid is used by C. glabrata species as a detoxification mechanism. The results gathered in this study advance the current knowledge on the mechanisms underlying the increased competitiveness of C. glabrata in the vaginal tract, a knowledge that can be used to guide more suitable strategies to treat infections caused by this pathogenic yeast.

    Diagnosis and treatment of sexually transmitted infections (STIs) is a public health priority, particularly in regions where the incidence of human immunodeficiency virus (HIV) infection is high. In most developing countries, STIs are managed syndromically. We assessed the adequacy of syndromic diagnosis of STIs, compared with laboratory diagnosis of STIs, and evaluated the association between STI diagnosis and the risk of HIV acquisition in a cohort of high-risk women. HIV-uninfected high-risk women (n = 242) were followed for 24 months. Symptoms of STIs were recorded, and laboratory diagnosis of common STI pathogens was conducted every 6 months. Forty-two cytokines were measured by Luminex in cervicovaginal lavage specimens at enrollment. Human immunodeficiency virus type 1 (HIV-1) infection was evaluated monthly. Only 12.3% of women (25 of 204) who had a laboratory-diagnosed, discharge-causing STI had clinically evident discharge. Vaginal discharge was thus a poor predictor of laboratory-diagnosed STIs (sensitivity, 12.3%; specificity, 93.8%). Cervicovaginal cytokine concentrations did not differ between women with asymptomatic STIs and those with symptomatic STIs and were elevated in women with asymptomatic STIs, compared with women with no STIs or bacterial vaginosis. Although laboratory-diagnosed STIs were associated with increased risk of HIV infection (hazard ratio, 3.3 [95% confidence interval, 1.5-7.2)], clinical symptoms were not. Syndromic STI diagnosis dependent on vaginal discharge was poorly predictive of laboratory-diagnosed STI. Laboratory-diagnosed STIs were associated with increased susceptibility to HIV acquisition, while vaginal discharge was not.

    The present study focuses on potential agents of chromoblastomycosis and other endemic diseases in the state of Paraná, Southern Brazil. Using a highly selective protocol for chaetothyrialean black yeasts and relatives, environmental samples from the living area of symptomatic patients were analysed. Additional strains were isolated from creosote-treated wood and hydrocarbon-polluted environments, as such polluted sites have been supposed to enhance black yeast prevalence. Isolates showed morphologies compatible with the traditional etiological agents of chromoblastomycosis, e.g. Fonsecaea pedrosoi and Phialophora verrucosa, and of agents of subcutaneous or systemic infections like Cladophialophora bantiana and Exophiala jeanselmei. Some agents of mild disease were indeed encountered. However, molecular analysis proved that most environmental strains differed from known etiologic agents of pronounced disease syndromes: they belonged to the same order, but mostly were undescribed species. Agents of chromoblastomycosis and systemic disease thus far are prevalent on the human host. The hydrocarbon-polluted environments yielded yet another spectrum of chaetothyrialean fungi. These observations are of great relevance because they allow us to distinguish between categories of opportunists, indicating possible differences in pathogenicity and virulence.

    Polycaprolactone (PCL) matrices were simultaneously loaded with the antiviral agents, tenofovir (TFV) and nevirapine (NVP), in combination to provide synergistic activity in the prevention of HIV transmission through the vaginal route. TFV and NVP were incorporated in PCL matrices at theoretical loadings of 10%TFV-10% NVP, 5%TFV-5%NVP and 5%TFV-10%NVP, measured with respect to the PCL content of the matrices. Actual TFV loadings ranged from 2.1% to 4.2% equating to loading efficiencies of about 41-42%. The actual loadings of NVP were around half those of TFV (1.2-1.9%), resulting in loading efficiencies ranging from 17.2% to 23.5%. Approximately 80% of the initial content of TFV was released from the PCL matrices into simulated vaginal fluid (SVF) over a period of 30 days, which was almost double the cumulative release of NVP (40-45%). The release kinetics of both antivirals over 30 days were found to be described most satisfactorily by the Higuchi model. In vitro assay of release media containing combinations of TFV and NVP released from PCL matrices confirmed a potential synergistic/additive effect of the released antivirals on HIV-1 infection of HeLa cells. These findings indicate that PCL matrices loaded with combinations of TFV and NVP provide an effective strategy for the sustained vaginal delivery of antivirals with synergistic/additive activity.

    Onychomycosis is the nail infection caused by a wide spectrum of fungi species, including yeasts, dermatophytes and filamentous fungi non-dermatophytes (FFND). This fungal infection represents an important medical problem because it involves the patient's life quality. The aim was to isolate and identify the fungal agents of onychomycosis, and to determine the in vitro susceptibility to antifungal agents. During the period of March 2008 to March 2009, 114 patients clinically suspected of having onychomycosis were examined. Demographic data, mainly age and gender were obtained from each patient. The nail samples collected (136) were submitted to direct examination with potassium hydroxide 20% and grown on Sabouraud dextrose agar. The in vitro antifungal susceptibility testing was performed according to the method of broth microdilution, recommended by the Clinical Laboratory Standards Institute (CLSI). Onychomycosis was observed in 95 (83.3%) patients, including 16 men (16.8%) and 79 women (83.2%), with mean age of 48.1 years. Candida parapsilosis, Trichophyton rubrum and Fusarium spp were the fungi most frequently isolated. The most of the isolated yeasts showed susceptibility to antifungal agents studied. Among filamentous fungi, high MIC values to itraconazole were found for T. rubrum and T. mentagrophytes, while Fusarium spp showed decreased susceptibility to itraconazole and voriconazole. C. parapsilosis was the most common fungal species isolated from patients with onychomycosis. The different response obtained by in vitro susceptibility testing to drugs shows the importance of these methods to assist clinicians in choosing the best therapeutic option. © 2011 The Authors.

    Full Text Available Defining the correlates of immune protection conferred by SIVΔnef, the most effective vaccine against SIV challenge, could enable the design of a protective vaccine against HIV infection. Here we provide a comprehensive assessment of immune responses that protect against SIV infection through detailed analyses of cellular and humoral immune responses in the blood and tissues of rhesus macaques vaccinated with SIVΔnef and then vaginally challenged with wild-type SIV. Despite the presence of robust cellular immune responses, animals at 5 weeks after vaccination displayed only transient viral suppression of challenge virus, whereas all macaques challenged at weeks 20 and 40 post-SIVΔnef vaccination were protected, as defined by either apparent sterile protection or significant suppression of viremia in infected animals. Multiple parameters of CD8 T cell function temporally correlated with maturation of protection, including polyfunctionality, phenotypic differentiation, and redistribution to gut and lymphoid tissues. Importantly, we also demonstrate the induction of a tissue-resident memory population of SIV-specific CD8 T cells in the vaginal mucosa, which was dependent on ongoing low-level antigenic stimulation. Moreover, we show that vaginal and serum antibody titers inversely correlated with post-challenge peak viral load, and we correlate the accumulation and affinity maturation of the antibody response to the duration of the vaccination period as well as to the SIVΔnef antigenic load. In conclusion, maturation of SIVΔnef-induced CD8 T cell and antibody responses, both propelled by viral persistence in the gut mucosa and secondary lymphoid tissues, results in protective immune responses that are able to interrupt viral transmission at mucosal portals of entry as well as potential sites of viral dissemination.

    Herpes genitalis, caused by HSV-2, is an incurable genital ulcerative disease transmitted by sexual intercourse. The virus establishes life-long latency in sacral root ganglia and reported to have synergistic relationship with HIV-1 transmission. Till date no effective vaccine is available, while the existing therapy frequently yielded drug resistance, toxicity and treatment failure. Thus, there is a pressing need for non-nucleotide antiviral agent from traditional source. Based on ethnomedicinal use we have isolated a compound 7-methoxy-1-methyl-4,9-dihydro-3H-pyrido[3,4-b]indole (HM) from the traditional herb Ophiorrhiza nicobarica Balkr, and evaluated its efficacy on isolates of HSV-2 in vitro and in vivo. The cytotoxicity (CC50), effective concentrations (EC50) and the mode of action of HM was determined by MTT, plaque reduction, time-of-addition, immunofluorescence (IFA), Western blot, qRT-PCR, EMSA, supershift and co-immunoprecipitation assays; while the in vivo toxicity and efficacy was evaluated in BALB/c mice. The results revealed that HM possesses significant anti-HSV-2 activity with EC50 of 1.1-2.8 µg/ml, and selectivity index of >20. The time kinetics and IFA demonstrated that HM dose dependently inhibited 50-99% of HSV-2 infection at 1.5-5.0 µg/ml at 2-4 h post-infection. Further, HM was unable to inhibit viral attachment or penetration and had no synergistic interaction with acyclovir. Moreover, Western blot and qRT-PCR assays demonstrated that HM suppressed viral IE gene expression, while the EMSA and co-immunoprecipitation studies showed that HM interfered with the recruitment of LSD-1 by HCF-1. The in vivo studies revealed that HM at its virucidal concentration was nontoxic and reduced virus yield in the brain of HSV-2 infected mice in a concentration dependent manner, compared to vaginal tissues. Thus, our results suggest that HM can serve as a prototype to develop non-nucleotide antiviral lead targeting the viral IE transcription for the

    Genital inflammation associated with sexually transmitted infections increases susceptibility to human immunodeficiency virus (HIV), but it is unclear whether the increased risk can reduce the efficacy of pre-exposure prophylaxis (PrEP). We investigated whether coinfection of macaques with Chlamydia trachomatis and Trichomonas vaginalis decreases the prophylactic efficacy of oral emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF). Macaques were exposed to simian/human immunodeficiency virus (SHIV) vaginally each week for up to 16 weeks and received placebo or FTC/TDF pericoitally. All animals in the placebo group were infected with SHIV, while 4 of 6 PrEP recipients remained uninfected (P = .03). Oral FTC/TDF maintains efficacy in a macaque model of sexually transmitted coinfection, although the infection of 2 macaques signals a modest loss of PrEP activity. PMID:26743846

    The ability to reproduce in captivity is an essential component of lion tamarin (Leontopithecus) conservation programs. However, infections such as vaginitis, cervicitis, and endometritis are important diseases that may influence the reproduction of these animals. Therefore, it is important to detect continuous or occasional vaginal microbial populations, and to understand their potential role as an endogenous source of infection [Collins, 1964; Blue, 1983; Pugh et al., 1986]. Vaginal swabs were collected from 25 female tamarins of the three currently available species (L. rosalia, L. chrysopygus, and L. chrysomelas) at the Center of Primatology in Rio de Janeiro, Brazil. The swabs were processed according to standard mycological protocols, and isolates were biochemically characterized. Fungal isolates were recovered from 16 animals (64.0%). The results showed that 70.6% of the isolated microorganisms consisted of yeast, including three species of Candida (mainly C. glabrata). We suggest that this species is a resident member of the normal vaginal flora in Leontopithecus. Filamentous fungi (mainly from Trichosporon, Aspergillus, and Penicilliumgenera) constituted 29.4% of the isolates, and were considered to be transitory contaminants of the genital area. We suggest that colonization of the vaginal environment is related to the endocrine pattern associated with the reproductive status of these animals, but not to parity.

    Pyomyositis is a purulent infection of skeletal muscle that arises from haematogenous spread, usually with abscess formation. It can develop after a transient bacteraemia of any cause. This type of infection has never been reported before in the literature after vaginal delivery. A 34-year-old woman had progressive severe pain in the left buttock and thigh and weakness in the left lower limb day 1 post spontaneous vaginal delivery. MRI showed severe oedema of the left gluteus, iliacus, piriformis and adductor muscles of the left thigh and a small fluid collection at the left hip joint. She was diagnosed with pyomyositis. She had fever of 37.9°C immediately postpartum and her risk factors for bacteraemia were a mild IV cannula-associated cellulitis and labour itself. She required prolonged treatment with antibiotics before significant clinical improvement was noted.

    Our purpose was to define influences on the patterns of the vaginal microflora. We enrolled 617 African American and Mexican American women in a 1-year longitudinal study of sexual behaviors and the vaginal microflora on the basis of the presence of gonorrhea, chlamydial infection, trichomoniasis, or syphilis at the initial visit. The patients were assigned randomly to a behavioral intervention or standard counseling regarding sexually transmitted disease. We reevaluated 508 (82%) and 549 (89%) women at 6 and 12 months, respectively. A comprehensive survey of lower genital tract organisms was conducted at baseline and at 6 and 12 months. Behavioral and microbiologic associations were screened by bivariate analysis. All variables associated with an organism at P 3 times a week, and cunnilingus, fellatio, and anal intercourse at the last sexual encounter. M hominis (but not Ureaplasma urealyticum ), Gardnerella vaginalis, and Lactobacillus species were associated with bacterial vaginosis. Lactobacillus species appeared to protect against bacterial vaginosis and infection with G vaginalis. Sexually transmitted diseases (caused by M hominis, N gonorrhoeae, C trachomatis, and T vaginalis ) were associated with each other. In contrast, hormonal status, vaginal blood, and foreign bodies had little effect. The presence of other microorganisms and race have a more consistent association with the presence or absence of a cervical-vaginal organism than sexual behavior, hormonal status, vaginal devices, or the presence of abnormal vaginal bleeding.

    Boric acid is a commonly cited treatment for recurrent and resistant yeast vaginitis, but data about the extent and mechanism of its antifungal activity are lacking. The aim of this study was to use in vitro methods to understand the spectrum and mechanism of boric acid as a potential treatment for vaginal infection. Yeast and bacterial isolates were tested by agar dilution to determine the intrinsic antimicrobial activity of boric acid. Established microbial physiology methods illuminated the mechanism of the action of boric acid against Candida albicans. C. albicans strains (including fluconazole-resistant strains) were inhibited at concentrations attainable intravaginally; as were bacteria. Broth dilution MICs were between 1563 and 6250 mg/L and boric acid proved fungistatic (also reflected by a decrease in CO(2) generation); prolonged culture at 50,000 mg/L was fungicidal. Several organic acids in yeast nitrogen broth yielded a lower pH than equimolar boric acid and sodium borate but were less inhibitory. Cold or anaerobic incubation protected yeast at high boric acid concentrations. Cells maintained integrity for 6 h in boric acid at 37 degrees C, but after 24 h modest intrusion of propidium iodide occurred; loss of plate count viability preceded uptake of vital stain. Growth at sub-MIC concentrations of boric acid decreased cellular ergosterol. The drug efflux pump CDR1 did not protect Candida as CDR1 expression was abrogated by boric acid. Boric acid interfered with the development of biofilm and hyphal transformation. Boric acid is fungistatic to fungicidal depending on concentration and temperature. Inhibition of oxidative metabolism appears to be a key antifungal mechanism, but inhibition of virulence probably contributes to therapeutic efficacy in vivo.

    The aim of the study was to investigate the effect of Bovine Herpesvirus 4 (BoHV-4) and Histophilus (H.) somni on fertility rate of cows in a Hungarian Holstein-Friesian dairy herd with purulent vaginal discharge (PVD). Non-pregnant cows (n = 188) with mature corpus luteum were treated with cloprostenol and 3 days later if they did not show oestrus, were examined by rectal palpation. Animals showing PVD (n = 60/31.9%/) and 14 controls with normal vaginal discharge (Score 0) were randomly selected and further examined by ultrasonography and blood samples were collected for detecting BoHV-4 DNA and transcervical guarded swabs were collected from the uterus for bacteriological examination. Although the majority of the examined animals were infected with BoHV-4 and H. somni including the control animals as well, in group of animals with PVD score 3, fewer animals became pregnant and the duration between the first treatment to pregnancy was significantly extended. Based on these clinical and comparative data, our results confirm that these two microorganisms together may impair important reproductive parameters which may cause large economic losses to dairy farms. © 2015 Blackwell Verlag GmbH.

    Full Text Available It is estimated that more than 340 million new cases of curable sexually transmitted infections occur every year throughout the world in men and women age (15–49years. Women bear an increasing burden of the epidemic as both caregivers for the ill and because of their heightened risk of infection due to biological, economic and social vulnerabilities. There is an urgent need for new prevention strategies that women can use themselves and initiate. A vaginal microbicide defined as substances intended to reduce or prevent transmission of HIV and/or other sexually transmitted infections (STIs when applied topically to genital mucosal surfaces, provides a woman-controlled method applied before sex that could kill, neutralize, or block HIV and other sexually transmitted diseases.

    Antifungal medications for intravaginal use have been available in the United States for more than a decade. Women may be inclined to self-diagnose yeast infections with any vaginal discharge or other vulvovaginal symptoms that they deem abnormal. As we saw in the first part of this article, "Abnormal vaginal discharge: Using office diagnostic testing more effectively" (J Fam Pract 2004; 53[10]:805-814), abnormal discharge is more likely to be bacterial vaginosis or no pathogen at all. Potential delay in diagnosis and treatment of a sexually transmitted disease is also a concern. Increasing resistance of Candida sp. to imidazoles is associated with indiscriminate use of over-the-counter products.

    Vaginal calculus is a rare disorder which has been reported in association with urethral diverticulum, urogenital sinus anomaly, bladder exstrophy and the tension-free vaginal tape (TVT) procedure. We report a 42-year-old woman who presented with persistent, intractable urinary tract infection (UTI) following a TVT procedure. Cystoscopy demonstrated an eroded tape with the formation of a bladder calculus, and the patient underwent laser cystolithotripsy and cystoscopic resection of the tape. Following this procedure, her UTI completely resolved and she remained asymptomatic for several years. Seven years later she presented with a solid vaginal mass. Pelvic examination followed by transvaginal ultrasonography and magnetic resonance imaging demonstrated a large vaginal calculus located at the lower third of the anterior vaginal wall adjacent to the bladder neck. This video presents the transvaginal excision and removal of the vaginal calculus.

  19. MiniCD4 microbicide prevents HIV infection of human mucosal explants and vaginal transmission of SHIV(162P3 in cynomolgus macaques.

    Directory of Open Access Journals (Sweden)

    Nathalie Dereuddre-Bosquet

    Full Text Available In complement to an effective vaccine, development of potent anti-HIV microbicides remains an important priority. We have previously shown that the miniCD4 M48U1, a functional mimetic of sCD4 presented on a 27 amino-acid stable scaffold, inhibits a broad range of HIV-1 isolates at sub-nanomolar concentrations in cellular models. Here, we report that M48U1 inhibits efficiently HIV-1(Ba-L in human mucosal explants of cervical and colorectal tissues. In vivo efficacy of M48U1 was evaluated in nonhuman primate (NHP model of mucosal challenge with SHIV(162P3 after assessing pharmacokinetics and pharmacodynamics of a miniCD4 gel formulation in sexually matured female cynomolgus macaques. Among 12 females, half were treated with hydroxyethylcellulose-based gel (control, the other half received the same gel containing 3 mg/g of M48U1, one hour before vaginal route challenge with 10 AID(50 of SHIV(162P3. All control animals were infected with a peak plasma viral load of 10(5-10(6 viral RNA (vRNA copies per mL. In animals treated with miniCD4, 5 out of 6 were fully protected from acquisition of infection, as assessed by qRT-PCR for vRNA detection in plasma, qPCR for viral DNA detection in PBMC and lymph node cells. The only infected animal in this group had a delayed peak of viremia of one week. These results demonstrate that M48U1 miniCD4 acts in vivo as a potent entry inhibitor, which may be considered in microbicide developments.

    Vulvovaginal candidiasis is a common infection among women worldwide, being Candida albicans the most commonly isolated species. Therefore, controlling this opportunistic yeast is one of the key factors for reducing nosocomial infection. We investigated several virulence properties of 28 vaginal strains of Candida isolated from Tunisian women suffering from vulvovaginitis. We also analyzed the virulence properties of a clinical Candida krusei strain and five Candida reference strains. Candida strains were subjected to microscopic analysis and culture in Candida ID2 chromogenic medium. The adhesive properties of these strains were estimated by the microtiter plate - the safranin-staining - and the Congo red agar (CRA) methods, for determining yeast ability to form biofilms on biomaterials used in urinary catheter manufacturing. Their potency to produce hydrolytic enzymes was also studied. Our results showed that nine out of the total studied strains produced phospholipase. In addition, very high protease activity was detected in 23 Candida strains. All Candida strains were beta-hemolytic and adhered to polystyrene microtiter plates in varying degrees. Two vaginal C. albicans strains were strongly adhesive to polystyrene and glass slides. Also, our results showed that vaginal Candida strains were more adhesive to the three tested materials than the reference strains. This study shows the presence of a range of virulence and adhesion factors in clinical isolates of vaginal Candida. Consequently, control and treatment of vaginal candidiasis as a means to prevent biofilm formation on urinary catheters is of crucial importance. Copyright © 2013 Revista Iberoamericana de Micología.

    Full Text Available CONTEXT AND OBJECTIVE: Vulvovaginal candidiasis (VVC is caused by abnormal growth of yeast-like fungi on the female genital tract mucosa. Patients with diabetes mellitus (DM are more susceptible to fungal infections, including those caused by species of Candida. The present study investigated the frequency of total isolation of vaginal Candida spp., and its different clinical profiles - colonization, VVC and recurrent VVC (RVVC - in women with DM type 2, compared with non-diabetic women. The cure rate using fluconazole treatment was also evaluated. DESIGN AND SETTING: Cross-sectional study conducted in the public healthcare system of Maringá, Paraná, Brazil. METHODS: The study involved 717 women aged 17-74 years, of whom 48 (6.7% had DM type 2 (mean age: 53.7 years, regardless of signs and symptoms of VVC. The yeasts were isolated and identified using classical phenotypic methods. RESULTS: In the non-diabetic group (controls, total vaginal yeast isolation occurred in 79 (11.8% women, and in the diabetic group in 9 (18.8% (P = 0.000. The diabetic group showed more symptomatic (VVC + RVVC = 66.66% than colonized (33.33% women, and showed significantly more colonization, VVC and RVVC than seen among the controls. The mean cure rate using fluconazole was 75.0% in the diabetic group and 86.7% in the control group (P = 0.51. CONCLUSION: We found that DM type 2 in Brazilian women was associated with yeast colonization, VVC and RVVC, and similar isolation rates for C. albicans and non-albicans species. Good cure rates were obtained using fluconazole in both groups.

    Geminiviruses, single-stranded DNA plant viruses, encode a replication-initiator protein (Rep) that is indispensable for virus replication. A potential cyclin interaction motif (RXL) in the sequence of African cassava mosaic virus Rep may be an alternative link to cell cycle controls to the known interaction with plant homologs of retinoblastoma protein (pRBR). Mutation of this motif abrogated rereplication in fission yeast induced by expression of wildtype Rep suggesting that Rep interacts via its RXL motif with one or several yeast proteins. The RXL motif is essential for viral infection of Nicotiana benthamiana plants, since mutation of this motif in infectious clones prevented any symptomatic infection. The cell-cycle link (Clink) protein of a nanovirus (faba bean necrotic yellows virus) was investigated that activates the cell cycle by binding via its LXCXE motif to pRBR. Expression of wildtype Clink and a Clink mutant deficient in pRBR-binding did not trigger rereplication in fission yeast. - Highlights: • A potential cyclin interaction motif is conserved in geminivirus Rep proteins. • In ACMV Rep, this motif (RXL) is essential for rereplication of fission yeast DNA. • Mutating RXL abrogated viral infection completely in Nicotiana benthamiana. • Expression of a nanovirus Clink protein in yeast did not induce rereplication. • Plant viruses may have evolved multiple routes to exploit host DNA synthesis.

    Infection with and persistence of high-risk human papillomavirus (HR HPV) are the strongest risk factors for cervical cancer. Little is known about the prevalence and role of concurrent sexually transmitted infections (STIs) found in HPV-infected female sex workers (FSW) in Africa. This study purports to test our a priori hypotheses that STIs are associated with genotypes pertaining to the α-group species 9. The objectives were to determine the prevalence of bacterial vaginosis (BV), Trichomonas vaginalis, and Candida spp in FSW, the association between these STIs and the prevalence of any potential HR and HR HPV genotypes in FSWs. A cross-sectional study design of 616 FSW from Western Kenya aged between 18 and 61 years during 2009-2015 using a peer recruitment sampling strategy. Inclusion criteria for the study entailed female sex and >18 years of age and having engaged in transactional sex in exchange for money, goods, services, or drugs in the last 3 months. Women were excluded if they were pregnant, potential HR and HR HPV genotype. The 2 most prevalent potential HR and HR genotypes were HPV 16 (16.10%) and HPV 59 (12.20%). BV was the most common infection (48.3%), followed by Trichomonas vaginalis (31.4%) and Candida spp (19.9%). A multivariate regression revealed significant associations with both α-group 9 and 6; BV and HPV 58 (adjusted odds ratio [aOR] = 2.3; 95% CI, 1.0-5.2; P = 0.05), Trichomonas vaginalis and HPV 31 and HPV 35 (aOR = 2.0; 95% CI, 1.0-3.8; P = 0.04 and aOR = 1.8; 95% CI, 1.0-3.3, P = 0.05 respectively); and between Candida spp and HPV 53 (aOR = 2.0; 95% CI, 1.1-4.0; P = 0.03) and 16 (aOR = 1.9; 95% CI, 1.1-3.3; P = 0.03). Snowball sampling may have inadvertently excluded FSW less likely to benefit from a social network. Significant associations between BV and HPV 58 and between Candida spp and HPV 16 and 53 suggest the need for sexually transmitted disease management within a cervical cancer prevention program. The probable synergistic

    Pregnancy represents a risk factor in the occurrence of vaginal candidiasis. To determine the prevalence and clinical features associated with abnormal vaginal discharge and C. albicans infection in pregnant women. High vaginal swab samples and data on epidemiological characteristics were collected from 400 pregnant women with complaints of abnormal vaginal discharge at booking clinic of University of Maiduguri Teaching Hospital. The data was analysed using SPSS 16.0 statistical software. The prevalence of abnormal vaginal discharge in pregnancy was 31.5%. The frequency of abnormal vaginal discharge was 183 (45.8%) among those aged 20-24 years, 291 (72.8%) in multipara, 223 (55.8%) in those with Primary education and 293 (73.2%) in unemployed. Vulval pruritus 300 (75.0%) was significantly related to abnormal vaginal discharge (P vaginal discharge in pregnancy was high in this study and C. albicans was the commonest cause. It is recommended that a pregnant woman complaining of abnormal vaginal discharge be assessed and Laboratory diagnosis done in order to give appropriate treatment.

    280 women have been tested by FISH to detect an HPV 16/18-infection of the portio uteri. In a group of 133 women treated by conisation (all with a history of abnormal smear and colposcopy) 67 (50%) were positive for HPV 16/18 DNA before the operation. Follow up examinations of 20 cases with positive HPV 16/18 test before conisation, showed 6 and 12 months after operation only in 3 cases a persistence of HPV 16/18 infection. Only 5 (6.4%) of 78 women with a history of conisation and diagnosis CIN III some years ago were positive for HPV 16/18. In another group of 47 elderly women, treated by abrasio and with normal cervical histology, only 5 (10.6%) had a positive result in the HPV 16/18 FISH-test. 2 (10.6%) of 22 women with normal smear and colposcopy (control group) were positive for HPV 16/18.

    Vulvovaginal candidiasis (VVC) or vaginal candidiasis is a common fungal infection of the genitals causing inflammation, irritation, itching, and vaginal discharge. Common yeast infections are caused by the yeast species C. albicans. However, there are other species of Candida such as C. dubliniensis which are considered as the causative agents of this infection. Hydrolytic enzymes such as proteinase and coagulase are known as virulence factors. The aim of this study was the molecular confirmation and differentiation of C. dubliniensis among C. albicans strains isolated from women with vulvovaginal candidiasis by PCR-Restriction Fragment Length Polymorphism (PCR-RFLP) and the evaluation of proteinase and coagulase activities. A total of 100 C. albicans strains isolated from women with vulvovaginal candidiasis referred to Shiraz medical clinics were enrolled in the study. All the isolates were primarily identified by conventional methods. PCR-RFLP method was used for the confirmation and identification of C. albicans and C. dubliniensis. Moreover, in vitro proteinase and coagulase activities of these isolates were evaluated using bovine serum albumin media and classical rabbit plasma tube test. As a result, PCR-RFLP identified 100% of the isolates as C. albicans, and no C. dubliniensis could be identified in this study. 84% of the isolates showed proteinase activity, whereas coagulase activity was only detected in 5% of the isolates. This study reveals that C. dubliniensis plays no role in vaginal candidiasis in Iranian patients. Proteinase production could be an essential virulence factor in C. albicans pathogenicity, but coagulase activity has less potential in this matter. Copyright © 2017 Elsevier Ltd.

    Our study aims to enhance the accuracy of the clinical diagnosis in patients with vaginal mesh extrusion following transvaginal mesh placement for pelvic organ prolapse using significant clinical parameters and risk factors. All patients who underwent vaginal mesh removal were retrospectively reviewed from January 2000 to May 2014. Eligible patients were divided into two groups according to the presence of vaginal mesh extrusion. A total of 862 patients, 798 were included. 357 (44.7%) had evidence of vaginal mesh extrusion, and 441 (55.3%) had no evidence of vaginal mesh extrusion. The mean age of the vaginal mesh extrusion group was slightly higher than in the group without vaginal mesh extrusion (58.7 ± 11.2 vs. 56.4 ± 11.5, respectively; p = 0.002). From multivariate analysis, the significant clinical correlations for vaginal mesh extrusion were vaginal bleeding [60 (16.9) vs. 14 (3.2%), p vaginal discharge [45 (12.6) vs. 18 (4.1%), p = 0.001]. The risk factors were multiple mesh implantations [218 (67.06) vs. 175 (39.68%), p vaginal atrophy, both local and systemic hormonal use, smoking status, and hysterectomy status, were not significantly different, as well as the clinical symptoms including dyspareunia, vaginal infection, and symptomatic vaginal bulge. Vaginal bleeding, hispareunia, and vaginal discharge were the most significant clinical predictors for raising suspicion of vaginal mesh extrusion. Multiple mesh implantations were a significant risk factor for extrusion.

    Epidemiological studies have demonstrated that herpes simplex virus 2 (HSV-2) infection significantly increases the risk of HIV-1 acquisition, thereby contributing to the expanding HIV-1 epidemic. To investigate whether HSV-2 infection directly facilitates mucosal HIV-1 acquisition, we used our transgenic hCD4/R5/cT1 mouse model which circumvents major entry and transcription blocks preventing murine HIV-1 infection by targeting transgenic expression of human CD4, CCR5, and cyclin T1 genes to CD4(+) T cells and myeloid-committed cells. Productive infection of mucosal leukocytes, predominantly CD4(+) T cells, was detected in all hCD4/R5/cT1 mice intravaginally challenged with an HIV-1 infectious molecular clone, HIV-Du151.2env-NLuc, which expresses an env gene (C.Du151.2) cloned from an acute heterosexually infected woman and a NanoLuc luciferase reporter gene. Lower genital tract HIV-1 infection after HIV-Du151.2env-NLuc intravaginal challenge was increased ~4-fold in hCD4/R5/cT1 mice coinfected with HSV-2. Furthermore, HIV-1 dissemination to draining lymph nodes was detected only in HSV-2-coinfected mice. HSV-2 infection stimulated local infiltration and activation of CD4(+) T cells and dendritic cells, likely contributing to the enhanced HIV-1 infection and dissemination in HSV-2-coinfected mice. We then used this model to demonstrate that a novel gel containing tenofovir disoproxil fumarate (TDF), the more potent prodrug of tenofovir (TFV), but not the TFV microbicide gel utilized in the recent CAPRISA 004, VOICE (Vaginal and Oral Interventions to Control the Epidemic), and FACTS 001 clinical trials, was effective as preexposure prophylaxis (PrEP) to completely prevent vaginal HIV-1 infection in almost half of HSV-2-coinfected mice. These results also support utilization of hCD4/R5/cT1 mice as a highly reproducible immunocompetent preclinical model to evaluate HIV-1 acquisition across the female genital tract. Multiple epidemiological studies have reported that

    Full Text Available Objective: To develop an in-house PCR based diagnostic assay for identification of strains isolated from symptomatic and asymptomatic subjects of India, targeting the 毬 -tubulin gene using specific primers. Methods: In the present study a primer set is designed to target a well-conserved region in the beta-tubulin gene of Trichomonas vaginalis (T. vaginalis. All strains of T. vaginalis were tested and successfully detected by PCR yielding a single predicted product of 198 bp in gel electrophoresis, while there was negative response with DNA from Giardia lamblia, Toxoplasma gondii, Leishmania donovani and Entamoeba histolytica. The sensitivity and specificity for a single T. vaginalis cell per PCR was achieved. Axenic Culture, performed with long term axenized T. vaginalis culture system, was routinely examined to identify T. vaginalis. Results: The PCR based investigations with 498 vaginal swab samples from women attending OPD clinics of Halberg Hospital Moradabad and Queen Mary ’s Hospital, Lucknow, India and 17 long term axenic cultures maintained at PGIMER, Chandigarh, India using primer set BTUB 1 & BTUB 2 showed sensitivity and specificity response of 98% and 100%, respectively, while wet preparation in clinically isolated samples responded up to 62.5%. The PCR product sequencing result of symptomatic strains (SS1 of T. vaginalis (744 bp long was submitted to NCBI (Accession No: JF513200. It shows maximum identity 98 % with XM_001284521 Trichomonas vaginalis G-3 beta-tubulin (btub putative partial mRNA. Conclusions: The data gathered in the present study entail that the diagnosis of T. vaginalis infection by PCR may be established as a sensitive and specific protocol, to be incorporated into a joint strategy for the screening of multiple STDs by employing molecular amplification technique. The merits and precautions of the protocol have been discussed.

    We estimated the association between prenatal exposure to maternal infections and the subsequent risk for epilepsy in childhood. We included 90,619 singletons who were born between September 1997 and June 2003 in the Danish National Birth Cohort and followed them up to December 2005. Information on maternal infections during pregnancy (cystitis, pyelonephritis, diarrhea, coughs lasting >1 week, vaginal yeast infection, genital herpes, venereal warts, and herpes labialis) was prospectively reported by mothers in 2 computer-assisted telephone interviews in early and midgestation; information on maternal cystitis and pyelonephritis during late period of pregnancy was also collected in a third interview after birth. Children who received a diagnosis of epilepsy as inpatients or outpatients were retrieved from the Danish National Hospital Register. We identified 646 children with a diagnosis of epilepsy during up to 8 years of follow-up time. Cox proportional hazards regression models were used to estimate incidence rate ratio and 95% confidence interval. Children who were exposed to maternal cystitis, pyelonephritis, diarrhea, coughs, and/or vaginal yeast infection some maternal infections in prenatal life had an increased risk for epilepsy. Coughs lasting >1 week were associated with an increased risk for epilepsy only in the first year of life, as was vaginal yeast infection only in children who were born preterm. These associations remained unchanged for children without cerebral palsy, congenital malformation, or a low Apgar score at 5 minutes. Prenatal exposure to some maternal infections was associated with an increased risk for epilepsy in childhood.

    The World Health Organization has recommended that testing for high-risk human papillomavirus (HPV) (hrHPV) infection be incorporated into cervical screening programs in all settings worldwide. In many high-burden, low-income countries, it will not be feasible to achieve high cervical screening coverage using hrHPV assays that require clinician-collected samples. We conducted the first evaluation of self-collected vaginal specimens compared with clinician-collected cervical specimens for the detection of hrHPV infection using the Xpert HPV test. Women aged 30 to 54 years attending two well-woman clinics in Papua New Guinea were invited to participate and provided self-collected vaginal and clinician-collected cervical cytobrush specimens. Both specimen types were tested at the point of care by using the Xpert HPV test. Women were given their cervical test result the same day. Those with a positive hrHPV test and positive examination upon visual inspection of the cervix with acetic acid were offered same-day cervical cryotherapy. A total of 1,005 women were enrolled, with 124 (12.3%; 95% confidence interval [CI], 10.3%, 14.4%) being positive for any hrHPV infection. There was a 99.4% overall percent agreement (OPA) between vaginal and cervical tests for HPV-16 (95% CI, 98.9%, 99.9%), a 98.5% OPA for HPV-18/45 (95% CI, 97.7%, 99.3%), a 94.4% OPA for other hrHPV infections (95% CI, 92.9%, 95.9%), and a 93.4% OPA for all hrHPV types combined (95% CI, 91.8%, 95.0%). Self-collected vaginal specimens had excellent agreement with clinician-collected cervical specimens for the detection of hrHPV infection using the Xpert HPV test. This approach provides for the first time an opportunity to incorporate point-of-care hrHPV testing into clinical cervical screening algorithms in high-burden, low-income settings.

    There have been conflicting reports of altered vaginal microbiota and infection susceptibility associated with contraception use. The objectives of this study were to determine if intrauterine contraception altered the vaginal microbiota and to compare the effects of a copper intrauterine device (Cu-IUD) and a levonorgestrel intrauterine system (LNG-IUS) on the vaginal microbiota. DNA was isolated from the vaginal swab samples of 76 women using Cu-IUD (n=36) or LNG-IUS (n=40) collected prior to insertion of intrauterine contraception (baseline) and at 6 months. A third swab from approximately 12 months following insertion was available for 69 (Cu-IUD, n=33; LNG-IUS, n=36) of these women. The V4 region of the bacterial 16S rRNA-encoding gene was amplified from the vaginal swab DNA and sequenced. The 16S rRNA gene sequences were processed and analyzed using the software package mothur to compare the structure and dynamics of the vaginal bacterial communities. The vaginal microbiota from individuals in this study clustered into 3 major vaginal bacterial community types: one dominated by Lactobacillus iners, one dominated by Lactobacillus crispatus and one community type that was not dominated by a single Lactobacillus species. Changes in the vaginal bacterial community composition were not associated with the use of Cu-IUD or LNG-IUS. Additionally, we did not observe a clear difference in vaginal microbiota stability with Cu-IUD versus LNG-IUS use. Although the vaginal microbiota can be highly dynamic, alterations in the community associated with the use of intrauterine contraception (Cu-IUD or LNG-IUS) were not detected over 12 months. We found no evidence that intrauterine contraception (Cu-IUD or LNG-IUS) altered the vaginal microbiota composition. Therefore, the use of intrauterine contraception is unlikely to shift the composition of the vaginal microbiota such that infection susceptibility is altered. Copyright © 2017 Elsevier Inc.

    Introduction: Vaginal discharge is one of the common reasons for gynecological consultation. Many of the causes of vaginitis have a disturbed vaginal microbial ecosystem associated with them. Effective treatment of vaginal discharge requires that the etiologic diagnosis be established and identifying the same offers a precious input to syndromic management and provides an additional strategy for human immunodeficiency virus prevention. The present study was thus carried out to determine the various causes of vaginal discharge in a tertiary care setting. Materials and Methods: A total of 400 women presenting with vaginal discharge of age between 20 and 50 years, irrespective of marital status were included in this study and women who had used antibiotics or vaginal medication in the previous 14 days and pregnant women were excluded. Results: Of the 400 women with vaginal discharge studied, a diagnosis was established in 303 women. Infectious causes of vaginal discharge were observed in 207 (51.75%) women. Among them, bacterial vaginosis was the most common cause seen in 105 (26.25%) women. The other infections observed were candidiasis alone (61, 15.25%), trichomoniasis alone (12, 3%), mixed infections (22, 5.5%) and mucopurulent cervicitis (7 of the 130 cases looked for, 8.46%). Among the non-infectious causes, 72 (18%) women had physiological vaginal discharge and 13 (3.3%) women had cervical in situ cancers/carcinoma cervix. Conclusion: The pattern of infectious causes of vaginal discharge observed in our study was comparable with the other studies in India. Our study emphasizes the need for including Papanicolaou smear in the algorithm for evaluation of vaginal discharge, as it helps establish the etiology of vaginal discharge reliably and provides a valuable opportunity to screen for cervical malignancies.

    The normal vaginal flora is highly complex, dominated by lactobacilli of doderlein that plays a vital role in maintaining the women's health and inhibits other pathogenic microorganisms. Fluctuation in local environment or exposure to any exogenous and endogenous sources changes the vaginal flora over a period of time. Disruption of the vaginal ecosystem changes the microflora of the healthy vagina, altering the pH and predisposing to lower reproductive tract infections. The change in the microflora of the female genital tract by pathogenic organisms may ascend from vagina to upper genital tract and may cause infertility. Although several studies demonstrate a higher prevalence of bacterial vaginosis in infertile population. The role of vaginal microbiome in infertility is not clear and need to be explored further. To compare the vaginal flora and analyse the incidence of asymptomatic vaginosis among healthy women and in women with infertility problems. A cross-sectional study was conducted over a period of six months at Sri Lakshmi Narayana Medical College and Hospital Puducherry, India. A total of 200 high vaginal swabs were collected from Group 1 which included 84 healthy women with regular menstrual cycles without any gynaecological disorder and from Group 2, 116 women with infertility problems attending fertility clinic within the age group of 18 to 45 years. All swabs were subjected to routine aerobic, anaerobic and fungal culture. Saline wet mount was performed for the detection of clue cells and Trichomonas vaginalis, 10% KOH was performed for demonstration of budding yeast cells and pseudo hyphae, Gram's staining to determine the presence of yeast cells, leucocytes and bacterial morphotypes. The smear was also graded using Nugent scoring system. The vaginal flora of Group 1 was dominated by Lactobacillus (40, 27.8 %) followed by Micrococcus (22, 15.3 %), Enterococcus (16, 11.1%), Coagulase negative Staphylococcus spp. (12, 8.3%). Whereas in Group 2, the

    Full Text Available Abstract Background In Tanzania, little is known on the species distribution and antifungal susceptibility profiles of yeast isolates from HIV-infected patients with primary and recurrent oropharyngeal candidiasis. Methods A total of 296 clinical oral yeasts were isolated from 292 HIV-infected patients with oropharyngeal candidiasis at the Muhimbili National Hospital, Dar es Salaam, Tanzania. Identification of the yeasts was performed using standard phenotypic methods. Antifungal susceptibility to fluconazole, itraconazole, miconazole, clotrimazole, amphotericin B and nystatin was assessed using a broth microdilution format according to the guidelines of the Clinical and Laboratory Standard Institute (CLSI; M27-A2. Results Candida albicans was the most frequently isolated species from 250 (84.5% patients followed by C. glabrata from 20 (6.8% patients, and C. krusei from 10 (3.4% patients. There was no observed significant difference in species distribution between patients with primary and recurrent oropharyngeal candidiasis, but isolates cultured from patients previously treated were significantly less susceptible to the azole compounds compared to those cultured from antifungal naïve patients. Conclusion C. albicans was the most frequently isolated species from patients with oropharyngeal candidiasis. Oral yeast isolates from Tanzania had high level susceptibility to the antifungal agents tested. Recurrent oropharyngeal candidiasis and previous antifungal therapy significantly correlated with reduced susceptibility to azoles antifungal agents.

    Trichomonas vaginalis is a common sexually transmitted infection (STI) causing vaginitis. Microscopy has poor sensitivity but is used for diagnosis of trichomoniasis in resource-poor settings. We aimed to provide a more reliable diagnosis of trichomoniasis by investigating an association with leukorrhea. Women presenting for evaluation of vaginal discharge, STI exposure, or preventative gynecologic examination were evaluated for Trichomonas infection. Vaginal pH was determined and microscopy was performed by the provider, who recorded the number of polymorphonuclear leukocytes (PMNLs) per epithelial cell and the presence of clue cells, yeast, and/or motile trichomonads. Leukorrhea was defined as greater than one PMNL per epithelial cell. Culture and a nucleic acid amplification test (NAAT) were used to detect T. vaginalis. Patients were evaluated for Chlamydia trachomatis and Neisseria gonorrhoeae using NAATs and bacterial vaginosis using Gram stains. Two hundred ninety-four women were enrolled, and 16% were found to have Trichomonas (46/294). Trichomonas infection was more common in parous non-Hispanic, black women, who reported low rates of contraceptive use (33% versus 17%; P = 0.02) and a STI history (85% versus 55%; P = 0.002). These women were more likely to report vaginal discharge (76% versus 59%; P = 0.02) and have an elevated vaginal pH (87% versus 48%; P < 0.001) and gonorrhea infection (15% versus 4%; P = 0.002). Leukorrhea was associated with a 4-fold-increased risk of Trichomonas infection. Leukorrhea on microscopy was associated with Trichomonas vaginitis. Patients with leukorrhea should be evaluated with more-sensitive tests for T. vaginalis, preferably NAATs, if microscopy is negative. PMID:23678058

    Pelvic organ prolapse is often co-existant with atrophy of the genital tract in older women who tend to prefer vaginal pessaries for prolapse. Vaginal estrogen therapy is used by some along with a support pessary for prolapse with no robust evidence to back this practice. We aimed to evaluate differences in complications of support pessaries for vaginal prolapse in postmenopausal women, with and without vaginal estrogen use. We prospectively assessed postmenopausal women attending the urogynaecology clinic for a pessary change. We asked them about the level of discomfort during pessary change (visual analogue scale for pain), discharge, bleeding and infection. Ethics approval was not required as this was a service evaluation project. Statistical analysis for relative risk was performed, including sub-group analysis for 'ring pessary' and 'non-ring group' (Shelf, Gellhorn, Shaatz). Between July 2013 and December 2014, we assessed 120 postmenopausal women using support pessaries for prolapse. The mean age was 70 years; 45% of the patients used vaginal estrogen. There were no statistically significant differences in complications with or without vaginal estrogen use, although the trend was higher amongst non-users. The 'non-ring' sub-group not using vaginal estrogen had a higher risk of vaginal ulceration, bleeding and discharge. Postmenopausal women may have lesser complications when using vaginal estrogen with a support pessary for prolapse, particularly with pessaries other than the ring. An adequately powered randomised controlled trial is needed to assess conclusively whether vaginal estrogen enhances comfort and reduces complications of support pessaries for prolapse. © The Author(s) 2015.

    Vaginal cancer is a rare gynecologic cancer with very little documentation. Literature search to have useful information for the management of vaginal cancer and share. We have searched the PUBMED database, Google search engine and other database. A total of 26 references were taken into account. Once spread from primary other cancers or vulva is ruled out, vaginal cancer is designated to be primary in origin. It was revealed that majority of vaginal cancers reported are squamous cell carcinomas. The most common risk factors implicated are Human Papiloma Virus, age. Most common presenting symptoms were abnormal vaginal bleeding,. Diagnosis requires pathological confirmation. Management depends on staging work-up. Vaginal cancer is staged by FIGO system of staging and TNM staging. There are many prognostic factors influencing the choice of treatment. Lymph node metastasis is one of the important prognostic factors, others to mention are histology, size, age. In a recent SEER analysis of over 2000 patients, the 5 year disease specific survival was 84% for stage 1, 75% for stage II and 57% for advanced tumors. Early carcinomas are generally treated with either surgery or radiation therapy. Advanced cancers are treated with radiation therapy with simultaneous administration of combined chemotherapy. Preventive strategies include safe sex and HPV vaccination. Primary vaginal cancer is a rare entity, if there is no history of cancer cervix or vulva in past or absence of cervical squamous cell carcinoma or vulvar carcinoma within 5 years is usually considered as primary vaginal cancer. Though early stage vaginal cancers have better outcome treated with surgery or radiotherapy or surgery followed by radiotherapy, radiotherapy alone is preferred mode of treatment in vaginal cancers.

    Micronutrients are increasingly used to treat psychiatric disorders including attention-deficit/hyperactivity disorder (ADHD), mood disorders, stress, and anxiety. However, a number of factors influence optimal response and absorption of nutrients, including the health of the gut, particularly the presence of yeast infections, such as Candida. As part of a wider investigation into the impact of micronutrients on psychiatric symptoms, many participants who experienced a yeast infection during their treatment showed a diminished response to the micronutrients. One case was followed systematically over a period of 3 y with documentation of deterioration in psychiatric symptoms (ADHD and mood) when infected with Candida and then symptom improvement following successful treatment of the infection with olive leaf extract (OLE) and probiotics. This case outlines that micronutrient treatment might be severely compromised by infections such as Candida and may highlight the importance of gut health when treating psychiatric disorders with nutrients. Given the role that inflammation can play in absorption of nutrients, it was hypothesized that the infection was impairing absorption of the micronutrients.

    Full Text Available Abstract Background Mycoplasma genitalium is an emerging sexually transmitted pathogen that has been associated with significant reproductive tract inflammatory syndromes in women. In addition, the strong association between severity of M. genitalium infection and Human Immunodeficiency Virus type 1 (HIV-1 shedding from the cervix suggests that innate responses to M. genitalium may influence pathogenesis of other sexually transmitted infections. Epithelial cells (ECs of the reproductive mucosa are the first cells contacted by sexually transmitted pathogens. Therefore, we first characterized the dynamics of intracellular and extracellular localization and resultant innate immune responses from human vaginal, ecto- and endocervical ECs to M. genitalium type strain G37 and a low-pass contemporary isolate, M2300. Results Both M. genitalium strains rapidly attached to vaginal and cervical ECs by 2 h post-infection (PI. By 3 h PI, M. genitalium organisms also were found in intracellular membrane-bound vacuoles of which approximately 60% were adjacent to the nucleus. Egress of M. genitalium from infected ECs into the culture supernatant was observed but, after invasion, viable intracellular titers were significantly higher than extracellular titers at 24 and 48 h PI. All of the tested cell types responded by secreting significant levels of pro-inflammatory cytokines and chemokines in a pattern consistent with recruitment and stimulation of monocytes and macrophages. Based on the elaborated cytokines, we next investigated the cellular interaction of M. genitalium with human monocyte-derived macrophages and characterized the resultant cytokine responses. Macrophages rapidly phagocytosed M. genitalium resulting in a loss of bacterial viability and a potent pro-inflammatory response that included significant secretion of IL-6 and other cytokines associated with enhanced HIV-1 replication. The macrophage-stimulating capacity of M. genitalium was independent

    To compare the vaginal route and laparoscopic suture for vaginal cuff closure (VCC) in patients undergoing a total laparoscopic hysterectomy (TLH). A total of 471 women who required hysterectomy were allocated to two groups. 261 women had TLH via VCC by the vaginal route and 210 women had TLH via VCC by laparoscopic suture. All TLHs were performed by the same laparoscopic surgeon. The cuff-related complications included vaginal disruption (3.4%), dehiscence (1.27%), vaginal vault bleeding (1.91%), vaginal spotting (19.32%), granulation (1.27%), cuff infection (1.49%), and yellowish vaginal discharge (6.16%). No difference in vaginal cuff complications was found between the laparoscopic and vaginal approach. The median operation time was significantly shorter for the laparoscopic suture (76.74 min, range 40-220; 95% CI 74.84-83.45) than the vaginal route for VCC (85.77 min, range 45-290; 95% CI 86.87-95.36) after hysterectomy (p < 0.001). For VCC with TLH, laparoscopic suture was a safe and less time-consuming procedure. The cuff-related complications were similar in the two groups. Copyright © 2010 S. Karger AG, Basel.

    The vaginal flora is a complicated environment, containing dozens of microbiological species in variable quantities and relative proportions. The frequent cause of vaginal discharge is an infection or colonization with different microorganisms. Some pathologic conditions causing vaginitis are well defined yet, 7-72% of women with vaginitis may remain undiagnosed and such forms of abnormal vaginal flora neither considered as normal, nor can be called bacterial vaginosis have been termed as 'intermediate flora' and its management probably differ from that of bacterial vaginosis. It is of crucial importance in pregnant females at risk of preterm delivery. The present study has been conducted especially to elucidate this type of aerobic vaginal isolates and their culture and sensitivity towards currently used antibiotics. This study was conducted at the Microbiology Department of Fauji Foundation Hospital, Rawalpindi over a period of two years (April 2004-March 2006). One thousand, nine hundred and twenty three high vaginal swabs, both from indoor and outdoor patients were collected, cultured and their susceptibility to various antibiotics was determined. Significant growth was obtained in 731 samples. The highest frequency of infection (39.5%) was observed at 31-40 years followed by 41-50 years (35.8%). About 76% were from outdoor and 24% were from indoor patients. Staphylococcus aureus was the most prevalent vaginal pathogen at 11-60 yrs & with highest prevalence at 31-40 years followed by 41-50 years. It was a predominant pathogen in both indoor (35%) as well as outdoor (41.6%) patients, followed by enteric gram-negative bacilli and other gram-positive cocci. There were very few antibiotics among the conventionally available aminoglycosides, third generation cephalosporins, penicillin, quinolones, sulfonamides and tetracyclines possessing good sensitivity (> 80%) against any one the common aerobic vaginal pathogens. The effective chemotherapeutics agents belong to

    The purpose of this study was to determine the prevalence of Ureaplasma urealyticum (UU) and Mycoplasma hominis (MH) in patients with preterm labor or preterm premature rupture of membranes (PPROM) and to determine the effect of these organisms on pregnancy outcomes based on the density of colonization. The study group consisted of 184 women with preterm labor or PPROM. Vaginal cultures for UU and MH were performed for all patients at admission, and the placentas were histologically evaluated after delivery. The prevalence of positive vaginal fluid cultures for genital mycoplasma was 62.5% (112/179). This group included 99 patients carrying only UU and 13 carrying both organisms. No patients were found to carry only MH. Compared to patients only positive for UU, patients with both organisms showed significantly decreased gestational age at birth and birth weight, and significant increases in the incidences of preterm birth, NICU admissions and histologic chorioamnionitis. Vaginal MH tends to be detected with UU, and patients carrying both organisms simultaneously had more severe adverse pregnancy outcomes compared to patients in preterm labor or PPROM who were only positive for UU.

    Full Text Available Healthy vaginal microbiota is dominated by Lactobacillus spp., which form a critical line of defence against pathogens, including Candida spp. The present study aims to identify vaginal lactobacilli exerting in vitro activity against Candida spp. and to characterize their antifungal mechanisms of action. Lactobacillus strains were isolated from vaginal swabs of healthy premenopausal women. The isolates were taxonomically identified to species level (L. crispatus B1-BC8, L. gasseri BC9-BC14 and L. vaginalis BC15-BC17 by sequencing the 16S rRNA genes. All strains produced hydrogen peroxide and lactate. Fungistatic and fungicidal activities against C. albicans, C. glabrata, C. krusei, C. tropicalis, C. parapsilosis and C. lusitaniae were evaluated by broth micro-dilution method. The broadest spectrum of activity was observed for L. crispatus BC1, BC4, BC5 and L. vaginalis BC15, demonstrating fungicidal activity against all isolates of C. albicans and C. lusitaniae. Metabolic profiles of lactobacilli supernatants were studied by 1H-NMR analysis. Metabolome was found to be correlated with both taxonomy and activity score. Exclusion, competition and displacement experiments were carried out to investigate the interference exerted by lactobacilli toward the yeast adhesion to HeLa cells. Most Lactobacillus strains significantly reduced C. albicans adhesion through all mechanisms. In particular, L. crispatus BC2, L. gasseri BC10 and L. gasseri BC11 appeared to be the most active strains in reducing pathogen adhesion, as their effects were mediated by both cells and supernatants. Inhibition of histone deacetylases was hypothesised to support the antifungal activity of vaginal lactobacilli. Our results are prerequisites for the development of new therapeutic agents based on probiotics for prophylaxis and adjuvant therapy of Candida infection.

    To evaluate associations between alterations in vaginal flora and clinical symptoms in low-risk pregnant women. Vaginal specimens from 245 pregnant women were analyzed by microscopy for vaginal flora. Signs and symptoms of vaginal infection were determined by patient interviews and gynecologic examinations. Abnormal vaginal flora was identified in 45.7% of the subjects. The final clinical diagnoses were bacterial vaginosis (21.6%), vaginal candidosis (10.2%), intermediate vaginal flora (5.2%), aerobic vaginitis (2.9%), mixed flora (2.9%) and other abnormal findings (2.9%). The percentage of women with or without clinical signs or symptoms was not significantly different between these categories. The presence of vaginal odor or vaginal discharge characteristics was not diagnostic of any specific flora alteration; pruritus was highly associated with candidosis (p vaginal odor was associated with bacterial vaginosis (p = 0.0026). The prevalence of atypical vaginal flora is common in our low-risk pregnant population and is not always associated with pathology. The occurrence of specific signs or symptoms does not always discriminate between women with different types of atypical vaginal flora or between those with abnormal and normal vaginal flora.

    Full Text Available Introduction. Despite the significant progress made in prevention, diagnosis, and treatment, there is still a high rate of vaginal dysbiosis in Kazakh women. The use of antibiotics in the treatment of vaginal dysbiosis contributes to the elimination of pathogens as well as microflora, which can lead to a decrease in local immunity and more favorable conditions for infection spread. The most physiologically safe and promising method for the restoration of vaginal biocenosis is the use of probiotics administered by a vaginal route.Methods. We have allocated 64 of cultures of Lactobacillus from the vaginal epithelium of healthy women of reproductive age and women with diagnosed bacterial vaginosis (BV. Identification of cultures was performed by PCR analysis of 16S ribosomal RNA.  Evaluation of biological significance was determined by the following criteria: high antagonistic activity against Candida albicans, Escherichia coli, Serratia marcescens, Proteus mirabilis, Klebsiella ozaenae, and Staphylococcus aureus; and production of hydrogen peroxide, resistance to antibiotics, adhesive activity. We studied the symbiotic relationship of selected biologically active of cultures to each other and received options for consortiums with  properties of  probiotics through co-cultivation.Results. Results of genotyping  showed that the isolated lactobacilli belong to the seven species: L. fermentum, L. salivarius, L. gasseri, L. crispatus, L. jensenii, L. plantarum, and L. delbrueskii. L. fermentum, L. salivarius, L. gasseri, and L. jensenii occur in women with suspected BV. The highest percentage of occurrence in the vagina of healthy women was L. fermentum (28%. Most strains of lactobacilli possess high inhibitory activity for all test-strains, except Candida albicans (37.5%. 56% of studied cultures revealed high adhesion to human erythrocytes. All lactobacillus strains were resistant to metronidazole, 80% to kanamycin, 57%  to vancomycin, and

    Vulvovaginal candidiasis is known as one of the most common fungal infection among women of reproductive age and considered as an important public health problem. In recent years, due to resistance to common antifungal medication, the use of traditional medicine of anti-fungal and herbal treatment increased. Therefore the objective of this study was to determine the effects of vaginal cream, mixture of yogurt and honey and comparing it with clotrimazole vaginal cream on symptoms of Vulvovaginal candidiasis in patients. In this randomized, triple blind clinical trial of 70 non-pregnant women infected with Candidal vulvovaginitis were placed in two groups of Vaginal cream mixed of yogurt and honey recipients (N=35) and clotrimazole vaginal cream (N=35). Both groups were treated for 7 days. At the beginning of study, Clinical and laboratory signs and symptoms were registered 7 and 14 days after treatment by questionnaire, observation form and secretions culture results. Data by chi-square test, t test, McNemar tests were analyzed by SPSS version 21. Significance level of 0.05 was considered. The result of present study reveals the significant differences in symptom improvement of ' yogurt and honey, than clotrimazole group (Pyogurt and honey" and clotrimazole (20% versus 8.6%) and second time cultivation (14 days after treatment) (17/1% versus 8.6%) were similar and there was no significant differences between the two groups. (P>0.05) CONCLUSION: This study indicated that he therapeutic effects of vaginal cream, yogurt and honey is not only similar with clotrimazole vaginal cream but more effective in relieving some symptoms of vaginal candidiasis. Therefore, the use of this product can be suggested as an herbal remedy for candida infection treatment.

    Full Text Available Introduction. Uncomplicated vulvovaginal candidiasis appears in 75% women of reproductive age. The most frequent causes are Candida albicans (85-95% or C. glabrata, and infrequently C. krusei, C. tropicalis, C. parapsilosis, C. pseudotropicalis, etc. Objective. The aim of the study was to investigate efficiency and safety of fenticonazole for vaginal candidiasis treatment. Methods. Therapeutic effect of a single 600 mg fenticonasole vaginal capsule was observed in 417 women, aged 16-67, in five centers in Serbia. In all women, before the treatment, vaginal candidiasis was confirmed by testing of vaginal smear. Based on smear findings and associated symptoms observed on the 7th and 28th day after therapy administration, treatment results were evaluated. On the next day after drug application the patients recorded by using a questionnaire their own feelings on withdrawal symptoms and possible side effects in the period prior to the first control. Results. Control after seven days showed a statistically significant decrease of symptoms. In 385 women, vaginal smear was found negative to yeast and yeast blastospores. Within the first seven days after treatment 84 women had to repeat therapy due to the persistence of symptoms or positive vaginal smear. After 28 days we recorded full recovery in 392 patients, clinical improvement in eight, no change in 16, and deterioration in one patient only. Side effects were very seldom, mostly in the form of a slight redness of the vulva and vagina, and mild itching during several days. Conclusion. Our observations confirmed good efficacy and safety of fenticonazole in the treatment of vaginal candidiasis.

  1. Lactobacilli Dominance and Vaginal pH: Why is the Human Vaginal Microbiome Unique?

    Full Text Available The human vaginal microbiome is dominated by bacteria from the genus Lactobacillus, which create an acidic environment thought to protect women against sexually transmitted pathogens and opportunistic infections. Strikingly, lactobacilli dominance appears to be unique to humans; while the relative abundance of lactobacilli in the human vagina is typically >70%, in other mammals lactobacilli rarely comprise more than 1% of vaginal microbiota. Several hypotheses have been proposed to explain humans' unique vaginal microbiota, including humans' distinct reproductive physiology, high risk of STDs, and high risk of microbial complications linked to pregnancy and birth. Here, we test these hypotheses using comparative data on vaginal pH and the relative abundance of lactobacilli in 26 mammalian species and 50 studies (N=21 mammals for pH and 14 mammals for lactobacilli abundance. We found that non-human mammals, like humans, exhibit the lowest vaginal pH during the period of highest estrogen. However, the vaginal pH of non-human mammals is never as low as is typical for humans (median vaginal pH in humans = 4.5; range of pH across all 21 non-human mammals = 5.4 to 7.8. Contrary to disease and obstetric risk hypotheses, we found no significant relationship between vaginal pH or lactobacilli abundance and multiple metrics of STD or birth injury risk (P-values ranged from 0.13 to 0.99. Given the lack of evidence for these hypotheses, we discuss two alternative explanations: the common function hypothesis and a novel hypothesis related to the diet of agricultural humans. Specifically, with regard to diet we propose that high levels of starch in human diets have led to increased levels of glycogen in the vaginal tract, which, in turn, promotes the proliferation of lactobacilli. If true, human diet may have paved the way for a novel, protective microbiome in human vaginal tracts. Overall, our results highlight the need for continuing research on non

    Streptococcal toxic shock syndrome (TSS) is a systemic illness usually caused in the setting of infection by group A Streptococcus (GAS). The primary infections are often invasive infections of the respiratory tract or necrotizing infections of the skin and soft tissue, but some infections occur without relevant focus. GAS vaginitis is a rare condition among adult women and is accordingly thought to be uncommon as a cause of streptococcal TSS. Here we report the cases of two postmenopausal women with streptococcal TSS secondary to GAS vaginitis, one aged 55 and one aged 60. Both came to our emergency department with complaints or symptoms of abdominal pain, fever, hypotension, and multi-organ failure. In both cases, the relevant factor associated with streptococcal infection was a recent episode of GAS vaginitis. Both underwent fluid management and 14 days of antibiotic treatment and fully recovered without complications. Vaginitis was likely to be the primary infectious trigger of TSS in these two cases. Intrauterine device insertion, endometrial biopsy, and post-partum state have all been previously reported in TSS patients, and the female genital tract has been described as a portal of entry. GAS vaginitis warrants appropriate treatment as it may progress to severe systemic infection as described.

    2004-12-01

    To understand women's perceptions and health seeking behavior and the association between vaginal discharge, clinical signs and laboratory findings as a presentation of sexually transmitted diseases (STD). We conducted five focus group discussions with women attending the outpatient department in a large public hospital in Katmandu, Nepal, during May-June 1997. We also interviewed seventy women presenting with vaginal discharge to the same hospital, through structured questionnaire. Women presenting with discharge were also examined and investigated for six common sexually transmitted diseases and reproductive tract infections. In the focus groups vaginal discharge was identified as a common disease distinct from STDs, for which women can seek treatment. STDs were considered as social diseases transmitted to women through multiple sexual partners and not from husband. Patients with vaginal discharge preferred traditional healers and pharmacist. Clinical signs were inconclusive for type of infection. Simple laboratory tests identified etiologic agent in 64 (91%) patients and the three commonest infections were Moniliasis (78%), Bacterial Vaginosis (25%) and Trichomoniasis (17%). Vaginal discharge may be used as a risk marker for identification of STDs by Primary Health Workers. Low cost investigations should be made available at the secondary care level for identification of most common Reproductive Tract Infections. Communication campaigns should target the misconceptions that exist in the communities local context related to the prevention, treatment and control of vaginal discharge and STDs.

  4. Pregnancy's stronghold on the vaginal microbiome.

    Full Text Available To assess the vaginal microbiome throughout full-term uncomplicated pregnancy.Vaginal swabs were obtained from twelve pregnant women at 8-week intervals throughout their uncomplicated pregnancies. Patients with symptoms of vaginal infection or with recent antibiotic use were excluded. Swabs were obtained from the posterior fornix and cervix at 8-12, 17-21, 27-31, and 36-38 weeks of gestation. The microbial community was profiled using hypervariable tag sequencing of the V3-V5 region of the 16S rRNA gene, producing approximately 8 million reads on the Illumina MiSeq.Samples were dominated by a single genus, Lactobacillus, and exhibited low species diversity. For a majority of the patients (n = 8, the vaginal microbiome was dominated by Lactobacillus crispatus throughout pregnancy. Two patients showed Lactobacillus iners dominance during the course of pregnancy, and two showed a shift between the first and second trimester from L. crispatus to L. iners dominance. In all of the samples only these two species were identified, and were found at an abundance of higher than 1% in this study. Comparative analyses also showed that the vaginal microbiome during pregnancy is characterized by a marked dominance of Lactobacillus species in both Caucasian and African-American subjects. In addition, our Caucasian subject population clustered by trimester and progressed towards a common attractor while African-American women clustered by subject instead and did not progress towards a common attractor.Our analyses indicate normal pregnancy is characterized by a microbiome that has low diversity and high stability. While Lactobacillus species strongly dominate the vaginal environment during pregnancy across the two studied ethnicities, observed differences between the longitudinal dynamics of the analyzed populations may contribute to divergent risk for pregnancy complications. This helps establish a baseline for investigating the role of the microbiome in

    Full Text Available BACKGROUND: Intravaginal practices (IVP are highly prevalent in sub-Saharan African and have been implicated as risk factors for HIV acquisition. However, types of IVP vary between populations, and detailed information on IVP among women at risk for HIV in different populations is needed. We investigated IVP among women who practice transactional sex in two populations: semi-urban, facility workers in Tanzania who engage in opportunistic sex work; and urban, self-identified sex workers and bar workers in Uganda. The aim of the study was to describe and compare IVP using a daily pictorial diary. METHODOLOGY/PRINCIPAL FINDINGS: Two hundred women were recruited from a HIV prevention intervention feasibility study in Kampala, Uganda and in North-West Tanzania. Women were given diaries to record IVP daily for six weeks. Baseline data showed that Ugandan participants had more lifetime partners and transactional sex than Tanzanian participants. Results from the diary showed that 96% of Tanzanian participants and 100% of Ugandan participants reported intravaginal cleansing during the six week study period. The most common types of cleansing were with water only or water and soap. In both countries, intravaginal insertion (e.g. with herbs was less common than cleansing, but insertion was practiced by more participants in Uganda (46% than in Tanzania (10%. In Uganda, participants also reported more frequent sex, and more insertion related to sex. In both populations, cleansing was more often reported on days with reported sex and during menstruation, and in Uganda, when participants experienced vaginal discomfort. Participants were more likely to cleanse after sex if they reported no condom use. CONCLUSIONS: While intravaginal cleansing was commonly practiced in both cohorts, there was higher frequency of cleansing and insertion in Uganda. Differences in IVP were likely to reflect differences in sexual behaviour between populations, and may warrant

    Full Text Available Vaginal foreign bodies are a complaint occasionally encountered in pediatric clinics and emergency departments, and when pediatric patients present with a vaginal foreign body sexual abuse may not be considered. We describe two children with vaginal foreign bodies who were found to have been sexually abused. Each child had a discharge positive for a sexually transmitted infection despite no disclosure or allegation of abuse. We recommend that all pre-pubertal girls who present with a vaginal foreign body should be considered as possible victims of sexual abuse and should receive a sexual abuse history and testing for sexually transmitted infections.

Among these procedures, vaginal rejuvenation is considered as one of the most controversial genital cosmetic surgical interventions and involves a range of surgical procedures performed by gynecologists or plastic surgeons to decrease the average diameter of the vagina, mainly for sexual reasons. In this narrative review, vaginal rejuvenation outcomes are examined in order to clarify the current scenario of the different vaginal rejuvenation techniques, as well as their effectiveness and associated complications. Psychological and ethical issues linked to these procedures are also addressed. Keywords: vaginal rejuvenation, female genital cosmetic surgery, vaginoplasty

    Study of in vivo antifungal activity of the hydroalcoholic extract (HE) and n-BuOH extract (BUTE) of Sapindus saponaria against azole-susceptible and -resistant human vaginal Candida spp. The in vitro antifungal activity of HE, BUTE, fluconazole (FLU), and itraconazole (ITRA) was determined by the broth microdilution method. We obtained values of minimal inhibitory concentration (MIC) and minimum fungicide concentration (MFC) for 46 strains of C. albicans and 10 of C. glabrata isolated from patients with vulvovaginal candidiasis (VVC). VVC was induced in hyperestrogenic Wistar rats with azole-susceptible C. albicans (SCA), azole-resistant C. albicans (RCA), and azole-resistant C. glabrata (RCG). The rats were treated intravaginally with 0.1 mL of HE or BUTE at concentrations of 1%, 2.5% and 5%; 100 μg/mL of FLU (treatment positive control); or distilled water (negative control) at 1, 24, and 48 h after induction of the infection, and the progress of VVC was monitored by culturing and scanning electron microscopy (SEM). The toxicity was evaluated in cervical cells of the HeLa cell line. The extracts showed in vitro inhibitory and fungicidal activity against all the isolates, and the MIC and MFC values for the C. glabrata isolates were slightly higher. In vivo, the SCA, RCA, and RCG infections were eliminated by 21 days post-infection, with up to 5% HE and BUTE, comparable to the activity of FLU. No cytotoxic action was observed for either extract. Our results demonstrated that HE and BUTE from S. saponaria show inhibitory and fungicidal activity in vitro, in addition to in vivo activity against azole-resistant vaginal isolates of C. glabrata and azole-susceptible and resistant isolates of C. albicans. Also considering the lack of cytotoxicity and the low concentrations of the extracts necessary to eliminate the infection in vivo, HE and BUTE show promise for continued studies with purified antifungal substances in VVC yeast isolates.

    The hemibiotrophic fungus Colletotrichum orbiculare first establishes a biotrophic infection stage in cucumber (Cucumber sativus) epidermal cells and subsequently transitions to a necrotrophic stage. Here, we found that C. orbiculare established hemibiotrophic infection via C. orbiculare WHI2, a yeast stress regulator homolog, and TOR (target of rapamycin) signaling. Plant defense responses such as callose deposition, H2O2, and antimicrobial proteins were strongly induced by the C. orbiculare whi2Δ mutant, resulting in defective pathogenesis. Expression analysis of biotrophy-specific genes evaluated by the promoter VENUS fusion gene indicated weaker VENUS signal intensity in the whi2Δ mutant, thereby suggesting that C. orbiculare WHI2 plays a key role in regulating biotrophic infection of C. orbiculare. The involvement of CoWHI2 in biotrophic infection was further explored with a DNA microarray. In the Cowhi2Δ mutant, TOR-dependent ribosomal protein-related genes were strikingly upregulated compared with the wild type. Moreover, callose deposition in the host plant after inoculation with the Cowhi2Δ mutant treated with rapamycin, which inhibits TOR activity, was reduced, and the mutant remained biotrophic in contrast to the untreated mutant. Thus, regulation of TOR by Whi2 is apparently crucial to the biotrophic stage of hemibiotrophic infection in C. orbiculare.

    Full Text Available Vaginal arteriovenous malformations are rare entities and their most common presentation is vaginal haemorrhage. This case report describes a 22-year-old woman who presented at 20 weeks of gestation with slow growing soft and tender swelling at anterior vaginal wall. Diagnosis was confirmed as vaginal vascular malformation on contrast enhanced magnetic resonance imaging. The mass did not subside after delivery and patient developed dyspareunia. It was successfully treated by angioembolisation using polyvinyl alcohol particles. Angioembolisation being safe and effective should be the treatment of first choice for symptomatic vaginal vascular malformation.

    Vaginal microbicides could reduce incidence of HIV. However, the current method of delivering gel formulations (standard applicator) can result in acceptability concerns/issues. This study evaluated the concept of using a non-woven textile material (modified tampon) for vaginal drug delivery. The study was nested within a Phase I randomized safety trial of lime juice concentrations used intra-vaginally. Of 47 women completing the safety trial, 16 were interviewed about their experiences. Overall, women found the concept of non-woven materials for vaginal drug delivery acceptable for use in delivering yeast medications (13 of 16) and STI/HIV preventives (10 of 16).

    Full Text Available Oropharyngeal candidiasis is the most common fungal infection among patients infected with the human immunodeficiency virus (HIV, and is treated empirically with topical or systemic antifungals. The objective of the present study was to investigate the possible antifungal action of the hydroalcoholic extract of Curcuma zedoaria (Christm. Roscoe, Zingiberaceae, on yeasts in this population. Samples were collected from HIV-positive patients who attended the Laboratory for Teaching and Research in Clinical Analysis at the Universidade Estadual de Maringá for routine exams. The isolated yeasts were identified at the genus and species levels through classical methodology. Next, tests of microdilution in broth were carried out to determine the profile of susceptibility of these yeasts towards the hydroalcoholic extract of C. zedoaria, following methodology standardised by the CLSI (2002. A total of 53 yeasts were identified, 49 of them C. albicans, two C. tropicalis and two C. glabrata. These yeasts were inhibited by low concentrations of the extract of C. zedoaria (between 1.95 and 15.63 μg/mL. In addition, 7.82 μg/mL inhibited 90% of the yeasts. Our results indicate a potent antifungal action for C. zedoaria and suggest more detailed studies with a view towards the practical application of this phytomedicine in topical pharmaceutical forms for the treatment of oral candidosis or candidiasis.

    This study reports a rapid PCR-based technique using a one-enzyme RFLP for discrimination of yeasts isolated from bovine clinical and subclinical mastitis milk samples. We analyzed a total of 1,486 milk samples collected over 1 yr in south Sardinia and northern Italy, and 142 yeast strains were preliminarily grouped based on their cultural morphology and physiological characteristics. Assimilation tests were conducted using the identification kit API ID 32C and APILAB Plus software (bioMérieux, Marcy l'Etoile, France). For PCR-RFLP analysis, the 18S-ITS1-5.8S ribosomal(r)DNA region was amplified and then digested with HaeIII, and dendrogram analysis of RFLP fragments was carried out. Furthermore, within each of the groups identified by the API or PCR-RFLP methods, the identification of isolates was confirmed by sequencing of the D1/D2 region using an ABI Prism 310 automatic sequencer (Applied Biosystems, Foster City, CA). The combined phenotypic and molecular approach enabled the identification of 17 yeast species belonging to the genera Candida (47.9%), Cryptococcus (21.1%), Trichosporon (19.7%), Geotrichum (7.1%), and Rhodotorula (4.2%). All Candida species were correctly identified by the API test and their identification confirmed by sequencing. All strains identified with the API system as Geotrichum candidum, Cryptococcus uniguttulatus, and Rhodotorula glutinis also produced characteristic restriction patterns and were confirmed as Galactomyces geotrichum (a teleomorph of G. candidum), Filobasidium uniguttulatum (teleomorph of Crypt. uniguttulatus), and R. glutinis, respectively, by D1/D2 rDNA sequencing. With regard to the genus Trichosporon, preliminary identification by API was problematic, whereas the RFLP technique used in this study gave characteristic restriction profiles for each species. Moreover, sequencing of the D1/D2 region allowed not only successful identification of Trichosporon gracile where API could not, but also correct identification of

    The objective of this publication was the analysis of laparoscopically assisted vaginal hysterectomies (LAVH) performed in Department of Surgical and Endoscopic Gynecology of Polish Mother Health Centre Research Institute. There was the analysis of 57 LAVHs performed from June 2002 to December 2003. Following parameters were evaluated: indications to LAVH, operating time, weight of the removed uterus, complications, blood loss, duration of postoperative hospitalisation, the day of introducing general diet, anesthetic and antibiotic demand in postoperative period. There were indications to LAVH: fibroid uterus, endometrial hyperplasia, endometrial cancer, adnexal mass, cervix dysplasia. Previous laparotomy and caesarean section, endometriosis, narrow vagina of non-parous women were additional indications to use of laparoscopy during the operation. Complications were found in two (3,5%) cases: bleeding to abdominal cavity from infundibulo-pelvic ligament demanding reoperation and superficial epigastric artery injury no demanding reoperation. There were no infection, conversion to laparotomy, abdominal cavity organs injury and other complications. It was observed short time of introducing general diet, low anesthetic consumption and short post-operation stay in hospital (mean 3,6 days). Laparoscopically assisted vaginal hysterectomy is an operation with a small risk of intra- and postoperative complications, quick return to general diet and full life activity, short post-operation stay in hospital, low anesthetic consumption and good cosmetic effect. Use of laparoscopic stage in vaginal hysterectomy make possible evasion of laparotomy in the situation of impossible performance of ordinary vaginal hysterectomy.

    Background Gingivitis has been linked to adverse pregnancy outcome (APO). Bacterial vaginosis (BV) has been associated with APO. We assessed if bacterial counts in BV is associated with gingivitis suggesting a systemic infectious susceptibilty. Methods Vaginal samples were collected from 180 women (mean age 29.4 years, SD ± 6.8, range: 18 to 46), and at least six months after delivery, and assessed by semi-quantitative DNA-DNA checkerboard hybridization assay (74 bacterial species). BV was defined by Gram stain (Nugent criteria). Gingivitis was defined as bleeding on probing at ≥ 20% of tooth sites. Results A Nugent score of 0–3 (normal vaginal microflora) was found in 83 women (46.1%), and a score of > 7 (BV) in 49 women (27.2%). Gingivitis was diagnosed in 114 women (63.3%). Women with a diagnosis of BV were more likely to have gingivitis (p = 0.01). Independent of gingival conditions, vaginal bacterial counts were higher (p gingivitis had higher counts of Prevotella bivia (p 1.0 × 104 cells) and a diagnosis of gingivitis was 3.9 for P. bivia (95% CI 1.5–5.7, p gingivitis in comparison to women with BV but not gingivitis. P. bivia and P. disiens may be of specific significance in a relationship between vaginal and gingival infections. PMID:19161595

The article discusses an effective and minimally invasive technique for resolving a case of massive vaginal-perineal bleeding after vaginal delivery complicated by ischiorectal fossa hematoma. A 36-year-old primipara white woman, 41 weeks 1 day pregnant, was admitted to our unit for beginning of labor. She experienced a precipitous delivery of a healthy male baby (3.72 kg, 51 cm in length), and spontaneous complete afterbirth of placenta and membranes. The intervention involved positioning of an hemostatic Bakri balloon device in the vagina, to compress the vaginal wall, ensuring that the draining apex was well positioned into the uterine cervix. The patient was discharged after having a puerperal course without further complications. Vaginal hemostatic Bakri balloon device shows hemostatic efficacy immediately assessable, is promptly removable, not interfering with subsequent surgical or radiological procedures, does not increase the risk of infections as other compressive procedures, allows flow of lochia, does not cause pain or discomfort in women, and permits adjustable compression when a drainage is placed during surgery. Despite the high cost, it does not show disadvantages.

    Ascariasis remains the most common helminth infection in humans. As an alternative or complementary approach to global deworming, a pan-anthelminthic vaccine is under development targeting Ascaris, hookworm, and Trichuris infections. As16 and As14 have previously been described as two genetically related proteins from Ascaris suum that induced protective immunity in mice when formulated with cholera toxin B subunit (CTB) as an adjuvant, but the exact protective mechanism was not well understood. As16 and As14 were highly expressed as soluble recombinant proteins (rAs16 and rAs14) in Pichia pastoris. The yeast-expressed rAs16 was highly recognized by immune sera from mice infected with A. suum eggs and elicited 99.6% protection against A. suum re-infection. Mice immunized with rAs16 formulated with ISA720 displayed significant larva reduction (36.7%) and stunted larval development against A. suum eggs challenge. The protective immunity was associated with a predominant Th2-type response characterized by high titers of serological IgG1 (IgG1/IgG2a > 2000) and high levels of IL-4 and IL-5 produced by restimulated splenocytes. A similar level of protection was observed in mice immunized with rAs16 formulated with alum (Alhydrogel), known to induce mainly a Th2-type immune response, whereas mice immunized with rAs16 formulated with MPLA or AddaVax, both known to induce a Th1-type biased response, were not significantly protected against A. suum infection. The rAs14 protein was not recognized by A. suum infected mouse sera and mice immunized with rAs14 formulated with ISA720 did not show significant protection against challenge infection, possibly due to the protein's inaccessibility to the host immune system or a Th1-type response was induced which would counter a protective Th2-type response. Yeast-expressed rAs16 formulated with ISA720 or alum induced significant protection in mice against A. suum egg challenge that associates with a Th2-skewed immune response

    Ensign-Hodges, Laura

    A method that could provide more uniform and longer-lasting drug delivery to mucosal surfaces holds the potential to greatly improve the effectiveness of prophylactic and therapeutic approaches for numerous diseases and conditions, including sexually transmitted infections and inflammatory bowel disease. However, the body's natural defenses, including adhesive, rapidly cleared mucus linings coating nearly all entry points to the body not covered by skin, has limited the effectiveness of drug and gene delivery by nanoscale delivery systems. Here, we investigate the use of muco-inert mucus-penetrating nanoparticles (MPP) for improving vaginal and gastrointestinal drug delivery. Conventional hydrophobic nanoparticles strongly adhere to mucus, facilitating rapid clearance from the body. Here, we demonstrate that mucoadhesive polystyrene nanoparticles (conventional nanoparticles, CP) become mucus-penetrating in human cervicovaginal mucus (CVM) after pretreatment with sufficient concentrations of Pluronic F127. Importantly, the diffusion rate of large MPP did not change in F127 pretreated CVM, implying there is no affect on the native pore structure of CVM. Additionally, there was no increase in inflammatory cytokine release in the vaginal tract of mice after daily application of 1% F127 for one week. Importantly, HSV virus remains adherent in F127-pretreated CVM. Mucosal epithelia use osmotic gradients for fluid absorption and secretion. We hypothesized that hypotonically-induced fluid uptake could be advantageous for rapidly delivering drugs through mucus to the vaginal epithelium. We evaluated hypotonic formulations for delivering water-soluble drugs and for drug delivery with MPP. Hypotonic formulations markedly increased the rate at which drugs and MPP reached the epithelial surface. Additionally, hypotonic formulations greatly enhanced drug and MPP delivery to the entire epithelial surface, including deep into the vaginal folds (rugae) that isotonic formulations

    Background: Syndromic management of sexually transmissible infections is commonly used in resource-poor settings for the management of common STIs; abnormal vaginal discharge (AVD) flowcharts are used to identify and treat cervical infection including Neisseria gonorrhoea and Chlamydia trachomatis. A systematic review and meta-analysis was undertaken to measure the diagnostic test performance of AVD flowcharts, including both World Health Organization (WHO)- and locally-adapted AVD flowcharts. Methods: A systematic search of multiple electronic databases was conducted to locate eligible studies published between 1991 and 2014. Flowcharts were categorised into one of 14 types based on: 1) use of WHO guidelines or locally-adapted versions; 2) use of risk assessment, clinical examination or both; and 3) symptomatic entry. Summary diagnostic performance measures calculated included summary sensitivity, summary specificity and diagnostic odds ratio. Results: Thirty-six studies, including data on 99 flowcharts, were included in the review. Summary sensitivity estimates for WHO flowcharts ranged from 41.2 to 43.6%, and for locally adapted flowcharts from 39.5 to 74.8%. Locally adapted flowcharts performed slightly better than the WHO flowcharts. A difference in performance was not observed between use of risk assessment or clinical examination. The AVD flowchart performed slightly better when it was not restricted to symptomatic women only. Conclusions: There was considerable variation in the performance of the AVD flowchart but overall it was a poor diagnostic tool regardless of whether risk assessment or clinical examination was included, or whether the flowchart was WHO or locally developed. Many women were treated unnecessarily and many women with cervical infection were not detected. We caution against their continued use for management of cervical infection.

  2. Opportunistic Pathogenic Yeasts

    Advances in medical research, made during the last few decades, have improved the prophylactic, diagnostic and therapeutic capabilities for variety of infections/diseases. However, many of the prophylactic and therapeutic procedures have been seen in many instances to exact a price of host-vulnerability to an expanding group of opportunistic pathogens and yeasts are one of the important members in it. Fortunately amongst the vast majority of yeasts present in nature only few are considered to have the capability to cause infections when certain opportunities predisposes and these are termed as ‘opportunistic pathogenic yeasts.’ However, the term ‘pathogenic’ is quite tricky, as it depends of various factors of the host, the ‘bug’ and the environment to manifest the clinical infection. The borderline is expanding. In the present century with unprecedented increase in number of immune-compromised host in various disciplines of health care settings, where any yeast, which has the capability to grow at 37 ° C (normal body temperature of human), can be pathogenic and cause infection in particular situation

    The objective of this work was to test the protective effect of a mixture (MM) constituted by kefir-isolated microorganisms (Lactobacillus plantarum, Lactobacillus kefir, Lc. lactis, Kluyveromyces marxianus and Saccharomyces cerevisiae) in a hamster model of infection with Clostridium difficile, an anaerobic Gram-positive bacterium that causes diarrhoea. Placebo or MM was administered ad libitum in drinking water from day 0 to the end of treatment. Hamsters received orally 200 μg of clyndamicin at day 7 and then were infected with 1 × 10(8) CFU of C. difficile by gavage. Development of diarrhoea and death was registered until the end of the protocol. Surviving animals were sacrificed at day 16, and a test for biological activity of clostridial toxins and histological stainings were performed in caecum samples. Six of seven infected animals developed diarrhoea and 5/7 died at the end of the experimental protocol. The histological sections showed oedema and inflammatory infiltrates with neutrophils and crypt abscesses. In the group of animals infected and treated with MM1/1000, only 1 of 7 hamsters showed diarrhoea and none of them died. The histological sections showed only a slight thickening of the mucosa with presence of lymphocytic infiltrate. These results demonstrate that an oral treatment with a mixture of kefir-isolated bacteria and yeasts was able to prevent diarrhoea and enterocolitis triggered by C. difficile.

    Enterohemorrhagic Escherichia coli (EHEC) are major food-borne pathogens responsible for serious infections ranging from mild diarrhea to hemorrhagic colitis and life-threatening complications. Shiga toxins (Stxs) are the main virulence factor of EHEC. The antagonistic effect of a prophylactic treatment with the probiotic strain Saccharomyces cerevisiae against EHEC O157:H7 was investigated using complementary in vitro human colonic model and in vivo murine ileal loop assays. In vitro, the probiotic treatment had no effect on O157:H7 survival but favorably influenced gut microbiota activity through modulation of short-chain fatty acid production, increasing acetate production and decreasing that of butyrate. Both pathogen and probiotic strains had individual-dependent effects on human gut microbiota. For the first time, stx expression was followed in human colonic environment: at 9 and 12 h post EHEC infection, probiotic treatment significantly decreased stx mRNA levels. Besides, in murine ileal loops, the probiotic yeast specifically exerted a trophic effect on intestinal mucosa and inhibited O157:H7 interactions with Peyer's patches and subsequent hemorrhagic lesions. Taken together, the results suggest that S. cerevisiae may be useful in the fight against EHEC infection and that host associated factors such as microbiota could influence clinical evolution of EHEC infection and the effectiveness of probiotics.

    Introduction. Vaginal vault prolapse is a common complication following vaginal hysterectomy with negative impact on women's quality of life due to associated urinary, anorectal and sexual dysfunction. A clear understanding of the supporting mechanism for the uterus and vagina is important in making the right choice of corrective procedure. Management should be individualised, taking into consideration the surgeon's experience, patients age, comorbidities, previous surgery and sex life. Result. Preexisting pelvic floor defect prior to hysterectomy is the single most important risk factor for vault prolapse. Various surgical techniques have been advanced at hysterectomy to prevent vault prolapse. Studies have shown the McCall's culdoplasty under direct visualisation to be superior. Vault prolapse repair rely on either the use of patient's tissue or synthetic materials and can be carried out abdominally or vaginally. Sacrospinous fixation and abdominal sacrocolpopexy are the commonly performed procedures, with literature in favour of abdominal sacrocolpopexy over sacrospinous fixation due to its reported higher success rate of about 90%. Other less commonly performed procedures include uterosacral ligament suspension and illiococcygeal fixation, both of which are equally effective, with the former having a high risk of ureteric injury. Colpoclesis will play a greater role in the future as the aging population increases. Mesh procedures are gaining in popularity, and preliminary data from vaginal mesh procedures is encouraging. Laparoscopic techniques require a high level of skill and experience. There are many controversies on the mechanism of prolapse and management techniques, which we have tried to address in this article. Conclusion. As the aging population increases, the incidence of prolapse will also rise, older techniques using native tissue will continue, while new techniques using the mesh needs to be studied further. The later may well be the way forward

    Full Text Available Objective: To investigate the antifungal activity of crude cultures of putative strains of lactic acid bacteria (LAB from a selection of Zimbabwean traditional and commercial food/ medicinal products against yeasts (strains of environmental isolates of Candida albicans and Rhodotorula spp.. Methods: Cultures of putative LAB from our selection of fermented products were enriched in de Man, Rogosa and Sharpe and isolated on de Man, Rogosa and Sharpe agar. Results: The crude microbial cultures from the products that showed high antifungal activities (zone of inhibition, mm were as follows: supernatant-free microbial pellet (SFMP from an extract of Melia azedarach leaves [(27.0 ± 2.5 mm] > cell-free culture supernatants (CFCS from Maaz Dairy sour milk and Mnandi sour milk [approximately (26.0 ± 1.8/2.5 mm] > CFCS and SFMP from Amansi hodzeko [(25.0 ± 1.5 mm] > CFCS from Parinari curatellifolia fruit [(24.0 ± 1.5 mm], SFMP from Parinari curatellifolia fruit [(24.0 ± 1.4 mm] and SFMP from mahewu [(20.0 ± 1.5 mm]. These cultures also showed high tolerance to acidic conditions (pH 4.0 and pH 5.0. However, culture from WAYA LGG (shown elsewhere to harbour antimicrobial activities showed no antifungal activity. The LAB could have inhibited yeasts by either competitive exclusion or the release of antimicrobial metabolites. Conclusions: Our cultures of LAB from a selection of Zimbabwean fermented products, especially Ziziphus mauritiana and fermented milk products have great potential for use as antifungal probiotics against yeast infections. Studies are ongoing to determine the exact mechanisms that are employed by the putative LAB to inhibit Candida albicans.

  8. Diagnosis of vaginal discharge by wet mount microscopy: a simple and underrated method.

    2011-06-01

    Vaginal discharge is highly variable in quality and quantity among different individuals, and even in the same individual during different periods of life. Vaginal discharge is most commonly caused by infection with sexually transmitted organisms or increased colonization by different facultative pathogenic microorganisms (i.e., Gardnerella vaginalis). Noninfectious causes of vaginal discharge are quite rare (10% noninfectious as compared to 90% infectious causes). Most common in women with a vaginal infection is bacterial vaginosis (40%-50% of cases), followed by vulvovaginal candidosis (20%-25%), and then trichomoniasis (15%-20%). If infection is suspected as the primary cause, a sample of the vaginal discharge should be taken and examined microscopically. When evaluating vaginal secretions by phase-contrast wet mount microscopy, knowledge of what is normal versus abnormal is very important. Knowledge of the sensitivity and specificity of wet mount microscopy in different clinical settings is also important. Obstetricians & Gynecologists, Family Physicians After completing this CME activity, physicians should be better able to evaluate lifetime changes in vaginal secretions, characterize the physiological and pathological appearance of vaginal discharge, assess the clinical practicality and usefulness of wet mount microscopy and use wet mount microscopy to diagnose bacterial vaginosis and other common vaginal infections.

    We have performed 26 vaginal radical trachelectomies (RTs) for patients with early invasive uterine cervical cancer since 2003 and, to date, have experienced 8 deliveries. The procedure has a high risk for preterm labor and the subsequent occurrence of preterm premature rupture of membranes (pPROM). We report the present situation and the limits of follow-up of pregnancy after vaginal RT. Our operative procedure is based on that of Dargent et al. We usually amputate the cervix approximately 10 mm below the isthmus. To remove the parametrium, we cut at the level of type II hysterectomy. Pregnancy courses after vaginal RT were studied in 8 patients with respect to symptoms, cervical length, and several infectious signs. We recommended that patients enter hospital early in their second trimester, and prophylactic daily vaginal disinfection with povidone-iodine and an ulinastatin vaginal suppository were administered. Careful checking for vaginal infectious signs, as well as cervical length and abdominal tension of patients was also performed. Four patients followed up with this modality were able to continue their pregnancies until late in the third trimester. However, this follow-up modality was not effective for patients who showed cervical incompetence due to slack cervical cerclage. They suffered from pPROM at 26 and 19 weeks of gestation. We need a new approach for the management of pregnant patients after vaginal RT with cervical incompetence due to slack cervical cerclage to prevent cervical infection.

  10. The vaginal microbiota, host defence and reproductive physiology.

    Smith, Steven B; Ravel, Jacques

    2017-01-15

    The interaction between the human host and the vaginal microbiota is highly dynamic. Major changes in the vaginal physiology and microbiota over a woman's lifetime are largely shaped by transitional periods such as puberty, menopause and pregnancy, while daily fluctuations in microbial composition observed through culture-independent studies are more likely to be the results of daily life activities and behaviours. The vaginal microbiota of reproductive-aged women is largely made up of at least five different community state types. Four of these community state types are dominated by lactic-acid producing Lactobacillus spp. while the fifth is commonly composed of anaerobes and strict anaerobes and is sometimes associated with vaginal symptoms. The production of lactic acid has been associated with contributing to the overall health of the vagina due to its direct and indirect effects on pathogens and host defence. Some species associated with non-Lactobacillus vaginal microbiota may trigger immune responses as well as degrade the host mucosa, processes that ultimately increase susceptibility to infections and contribute to negative reproductive outcomes such as infertility and preterm birth. Further studies are needed to better understand the functional underpinnings of how the vaginal microbiota affect host physiology but also how host physiology affects the vaginal microbiota. Understanding this fine-tuned interaction is key to maintaining women's reproductive health. © 2016 The Authors. The Journal of Physiology © 2016 The Physiological Society.

    Full Text Available Background Reproductive tract infections (RTIs in pregnancy are an important cause of fetal and neonatal morbidity, sometimes with serious complications. Chlamydia trachomatis causes ectopic pregnancy, conjunctivitis, pneumonia and RTIs in newborn babies. Listeria monocytogenes and Streptococcus agalactiae can give neonatal sepsis and meningitis, and Trichomonas vaginalis causes premature birth. Objectives To update local epidemiology of RTIs in pregnancy in order to to implement efficacious screening and prevention programs. Methods Between January- December 2006, at the Padua’s Hospital Microbiology and Virology Service,we investigated 2000 asimptomatic pregnant women, 18-45 years old, Italian and foreigners.We collected vaginal and cervical swabs for the microscopy, the culture for Neisseria gonorrhoeae, Trichomonas vaginalis, Mycoplasma spp., Streptococcus agalactiae, Listeria monocytogenes, and other bacteria and yeasts, and for the molecular assay for Chlamydia trachomatis. Results The prevalence of Chlamydia trachomatis and Trichomonas vaginalis in our population were 2.06% and 0.20%, respectively. Neisseria gonorrhoeae was not detected. Sexually transmitted infections (STIs were more frequent among foreigners, and in women aged 18-30.The prevalence of Streptococcus agalactiae was 8.69% for Italian, and 7.54% for foreigners.We didn’t find any case of maternal colonization by Listeria monocytogenes. Conclusions From the obtained results ideas have emerged to arrange a qualitative and quantitative optimization of the diagnosis of RTIs, implementing diagnostic paths based on the different typologies of patients and on the local epidemiology. The cultural research of Listeria monocytogenes takes a long time, perhaps a molecular one, because of fastness and sensitivity, could be more useful.

    Sociodemographic, behavioral and clinical correlates of the vaginal microbiome (VMB) as characterized by molecular methods have not been adequately studied. VMB dominated by bacteria other than lactobacilli may cause inflammation, which may facilitate HIV acquisition and other adverse reproductive health outcomes. We characterized the VMB of women in Kenya, Rwanda, South Africa and Tanzania (KRST) using a 16S rDNA phylogenetic microarray. Cytokines were quantified in cervicovaginal lavages. Potential sociodemographic, behavioral, and clinical correlates were also evaluated. Three hundred thirteen samples from 230 women were available for analysis. Five VMB clusters were identified: one cluster each dominated by Lactobacillus crispatus (KRST-I) and L. iners (KRST-II), and three clusters not dominated by a single species but containing multiple (facultative) anaerobes (KRST-III/IV/V). Women in clusters KRST-I and II had lower mean concentrations of interleukin (IL)-1α (p infections (STIs; ptrend = 0.07) and urinary tract infection (UTI; p = 0.06), and a higher proportion of women in clusters KRST-I and II had vaginal candidiasis (ptrend = 0.09), but these associations did not reach statistical significance. Women who reported unusual vaginal discharge were more likely to belong to clusters KRST-III/IV/V (p = 0.05). Vaginal dysbiosis in African women was significantly associated with vaginal inflammation; the associations with increased prevalence of STIs and UTI, and decreased prevalence of vaginal candidiasis, should be confirmed in larger studies.

    Vaginal symptoms are a common chief complaint amongst women visiting outpatient clinics in rural Haiti. A systematic sample of 206 consecutive women over age 18 with gynaecological symptoms underwent gynaecologic examination and laboratory testing for chlamydia, gonorrhoea, syphilis, HIV infection, trichomoniasis, candidiasis, and bacterial vaginosis. Among 206 women, 174 (84%) presented with vaginal discharge, 165 (80%) with vaginal itching, 123 (60%) with vaginal pain or dysuria, and 18 (9%) with non-traumatic vaginal sores or boils. Laboratory results were positive forChlamydia trachomatisin 5.4% (11/203), syphilis in 3.5% (7/202), HIV in 1.0% (2/200), andNeisseria gonorrhoeaein 1.0% (2/203). Among those that had microscopy, hyphae suggestive of candidiasis were visualized in 2.2% (1/45) and no cases of trichomoniasis were diagnosed 0% (0/45). Bacterial vaginosis was diagnosed in 28.3% (13/46). The prevalence of chlamydia was 4.9 (95% CI: 1.3-17.7) times greater among those 25 years of age and under (10.8%) than those older (2.3%). Chlamydia and bacterial vaginosis were the most common sexually transmitted infection and vaginal condition, respectively, in this study of rural Haitian adult women. The higher risk of chlamydia in younger women suggests education and screening programmes in young women should be considered. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Vaginitis may be diagnosed as bacterial vaginosis, vulvovaginal candidiasis, trichomoniasis, or coinfection. A new molecular test assays the vaginal microbiome and organisms that cause three common infections. The objective of the trial was to evaluate the clinical accuracy of the investigational test for vaginal swabs collected by patients (self) or clinicians. The primary and secondary outcomes were to compare the investigational test with reference methods for the three most common causes of vaginitis and compare clinician-collected with self-collected swabs. We conducted a cross-sectional study in which women with symptoms of vaginitis were recruited at ten clinical centers and consented to the investigation between May and September 2015. The woman collected a vaginal swab, sheathed, and then handed it to the clinician. These swabs were to evaluate how self-collected swabs compared with clinician-collected swabs. The clinician collected an investigational test swab and reference test swabs. From 1,740 symptomatic patients, clinician-collected and self-collected vaginal swabs were evaluated by the molecular test and six tests. The reference methods for bacterial vaginosis were Nugent's score and Amsel's criteria for intermediate Nugent results. The reference methods for Candida infection were isolation of any potential Candida microorganisms from inoculation of two culture media: chromogenic and Sabouraud agar and sequencing. The reference methods for trichomoniasis were wet mount and culture. For clinician-collected swabs, by reference methods, bacterial vaginosis was diagnosed in 56.5%, vaginal candidiasis in 32.8%, trichomoniasis in 8%, and none of the three infections in 24% with a coinfection rate of 20%. The investigational test sensitivity was 90.5% (95% confidence interval [CI] 88.3-92.2%) and specificity was 85.8% (95% CI 83.0-88.3%) for bacterial vaginosis. The investigational test sensitivity was 90.9% (95% CI 88.1-93.1%) and specificity was 94

    Full Text Available Aims: This study was undertaken to estimate the incidence of bacterial vaginosis (BV and other vaginal infections during pregnancy and its association with urinary tract infections (UTI and its consequences on pregnancy outcome, maternal and fetal morbidity and mortality. Settings and Design: Prospective cohort study. Materials and Methods: The present prospective cohort study was conducted on 200 women attending the antenatal clinic (ANC of a tertiary hospital. All pertinent obstetric and neonatal data covering antenatal events during the course of pregnancy, delivery, puerperium and condition of each newborn at the time of birth were collected. BV was detected by both Gram stain and gold standard clinical criteria (Amsel′s composite criteria. Statistical analysis used: Data were analyzed using SPSS version 9. Fischer′s exact test, chi square tests and Student′s′ test has been used for analysis. The probability of 5% was considered as significant for continuous variables such as age, period of gestation and birth weight. Odds ratio (OR and confidence interval (CI with 95% probability were determined. Results: The incidence of bacterial vaginosis was 41 in 200 patients. Adverse outcomes such as preterm labor, PROM and fetal complications were found more in pregnant women who had bacterial vaginosis (N=41, bacterial vaginosis with UTI (N=14 as compared to those without bacterial vaginosis (N=118. Conclusions: The incidence of poor pregnancy outcome was higher in bacterial vaginosis with UTI. Prevention of BV and UTI is cost effective to minimize the pregnancy-related complications and preterm labor to decrease in perinatal and maternal mortality and morbidity. We recommend all antenatal patients should be screened for the presence of bacterial vaginosis, other infections and UTI.

    its recurrent forms, causing true devastation of quality of life. Unraveling the fungal factors causing inflammation is important to be able to devise novel tools to fight the disease. In an experimental murine model, we have discovered that aspartyl proteinases, particularly Sap2, may cause the same inflammatory signs of vaginitis caused by the fungus and that anti-Sap antibodies and the protease inhibitor Pepstatin A almost equally inhibit Sap- and C. albicans-induced inflammation. Sap-induced vaginitis is an early event during vaginal infection, is uncoupled from fungal growth, and requires Sap and caspase-1 enzymatic activities to occur, suggesting that Sap or products of Sap activity activate an inflammasome sensor of epithelial cells. Our data support the notion that anti-Sap antibodies could help control the essence of candidal vaginitis, i.e., the inflammatory response. Copyright © 2015 Pericolini et al.

    2007-06-16

    The 1996 practice guideline of the Dutch College of General Practitioners (NHG) on vaginal discharge has been updated. Most women who visit their doctor with complaints about vaginal discharge do not have an increased risk of a sexually-transmitted disease. Investigations into vaginal discharge comprise history taking, physical examination and microscopic analysis in the laboratory of the general practitioner. Additional investigation into Chlamydia, gonorrhoea and Trichomonas infection is only necessary if the patient history reveals an increased risk of a sexually-transmitted disease. A Candida infection or bacterial vaginosis should only be treated if the patient experiences bothersome complaints. Treatment of a Candida infection consists of a vaginally applied imidazole compound. Bacterial vaginosis can be treated with oral administration of metronidazole. Patients with vaginal fluor can be examined and, if necessary, treated by their general practitioner. Referral to a gynaecologist is rarely necessary.

    Vault prolapse repair rely on either the use of patient's tissue or synthetic materials and can be carried out abdominally or vaginally. Sacrospinous fixation and abdominal sacrocolpopexy are the commonly performed procedures, with literature in favour of abdominal sacrocolpopexy over sacrospinous fixation due to its reported higher success rate of about 90%. Other less commonly performed procedures include uterosacral ligament suspension and illiococcygeal fixation, both of which are equally effective, with the former having a high risk of ureteric injury. Colpoclesis will play a greater role in the future as the aging population increases. Mesh procedures are gaining in popularity, and preliminary data from vaginal mesh procedures is encouraging. Laparoscopic techniques require a high level of skill and experience. There are many controversies on the mechanism of prolapse and management techniques, which we have tried to address in this article. Conclusion. As the aging population increases, the incidence of prolapse will also rise, older techniques using native tissue will continue, while new techniques using the mesh needs to be studied further. The later may well be the way forward in future.

    This study was undertaken to evaluate a diagnostic panty liner (VI-SENSE) (Common Sense, Caesarea, Israel) developed to facilitate diagnosis of vaginal infections by detecting disordered acidity level. Five hundred sixteen women with vulvovaginal symptoms were enrolled. Final clinical diagnosis included Amsel criteria, Gram stain analysis, pH determination, and Trichomonas vaginalis and Candida culture. VI-SENSE strip color status estimated by patients was compared with clinical diagnosis and pH measurement by using nitrazine paper. Statistical analysis included sensitivity and specificity calculations. The VI-SENSE test was positive in 226 of 249 patients (90.8%) with bacterial vaginosis or trichomoniasis. Nitrazine pH paper revealed elevated pH in 165 (66.5%) and the amine test was positive in 160 (64.3%) patients. The VI-SENSE test was negative in 217 of 267 patients (81.3%) without trichomoniasis or bacterial vaginosis. The VI-SENSE was positive in 85 of 92 women (92%), with mixed vaginal infection including Candida and bacterial vaginosis or trichomoniasis. Amine test, nitrazine pH paper and physician diagnosis relying only on speculum examination were inferior and positive in only 65 (70%), 59 (64%), and 66 (72%) patients, respectively. The VI-SENSE test was found to be superior to traditional individual tests in facilitating preliminary diagnosis of vaginal infections.

    The aim of this study was to evaluate how konjac glucomannan hydrolysates (GMH) could support the healthy re-colonisation of vaginal microflora post infections. A total of 26 female patients (12 controls and 14 treatments) aged 18 to 25 suffering from vaginal infection were recruited for this study. Patients were assigned randomly into two groups to receive a standard antifungal treatment or a standard antifungal treatment plus pessary capsules containing 200 mg GMH (twice a week for thirty days). Patients were assessed on day zero, sixteen and thirty of the trial. Several parameters were determined including yeast and bacterial counts, the KOH test, pH, Gram staining and wet mount microscopic observations. The results showed that the counts of Candida were diminished completely with antifungal treatment for both groups. However, the total bacterial counts increased with time in the GMH pessary group unlike the control. The normalised average KOH scores were reduced sharply with time in both groups although in the control group scores started to increase after sixteen days. The normalised average white blood cell scores also decreased with time for both groups. Epithelial cell scores decreased only for the GMH pessary group while clue cells and yeast-like fungi decreased with time for both control and GMH pessary groups. These results indicate the improvement of vaginal health recovery (post antifungal treatment for Candida infection) and especially the presence of healthy microflora due to the introduction of GMH in the vagina. The data indicate that it would be worth examining further the health benefits of GMH in a vaginal health format with a view to employing the material as a prophylactic or therapeutic agent. It provides an alternative approach to reducing vaginal infections and promoting consumer health.

    To investigate the relationship between vaginal and intestinal candida in patients with vulvovaginal candidiasis by using microbiological and molecular methods. The samples of vaginal discharge and anal swabs were collected from 148 cases with vulvovaginal candidiasis, followed by fungal culture, identification, purification and genome DNA extraction. The genome sequences from respective locations were aligned and typed according to their homology analyzed by internal transcribed spacer (ITS) PCR and random amplified polymorphic DNA (RAPD) PCR. Patients with vulvovaginal infection or those with infections in intestine and vulvovagina were pooled respectively, while the recurrent incidences after local anti-fungal treatments were analyzed. Candida albicans is the dominant pathogen in 148 cases with vulvovaginal candidiasis (91.9%, 136/148); 33.1% (49/148) of patients with vulvovaginal candidiasis were infected in both intestine and vulvovagina. While 92% (22/24) of patients with intestinal and vaginal candida infection showed high homology. The recurrent rate of patients with vulvovaginal candidiasis complicated with concurrent intestinal candida infection (7/14) was significantly higher than that of solo vaginal infected patients [21% (6/29)] after vaginal treatment (Pinfection of vulvovaginal candidiasis is highly associated with the concurrent infection of intestinal candida. The recurrent rate is high in patients with vulvovaginal candidiasis with concurrent infection of intestinal candida after vaginal treatment. The general management to those patients infected by both vulvovaginal and intestinal candida is necessary in reducing the recurrence of the disease.

  4. Vaginal haemangioendothelioma: an unusual tumour.

    Vaginal tumours are uncommon and this is a particularly rare case of a vaginal haemangioendothelioma in a 38-year-old woman. Initial presentation consisted of symptoms similar to uterovaginal prolapse with "something coming down". Examination under anaesthesia demonstrated a necrotic anterior vaginal wall tumour. Histology of the lesion revealed a haemangioendothelioma which had some features of haemangiopericytoma. While the natural history of vaginal haemangioendothelioma is uncertain, as a group, they have a propensity for local recurrence. To our knowledge this is the third reported case of a vaginal haemangioendothelioma. Management of this tumour is challenging given the paucity of literature on this tumour. There is a need to add rare tumours to our "knowledge bank" to guide management of these unusual tumours.

    To show that in selected cases laparoscopic sacrocolpopexy can be used for the treatment of recurrent pelvic organ prolapse after vaginal mesh surgery. Step-by-step examination of the technique using an educative video. Institutional review board approval was obtained. The authors describe two clinical cases of treatment of recurrent pelvic organ prolapse, after a vaginal mesh surgery, using laparoscopic sacrocolpopexy. A 56-year old patient (para 3, gravida 2) presented with the sentation of bulging in the vagina. On physical examination, the patient had a grade 2-3 vaginal apical prolapse and a stage 4 rectocele. She had a slight mesh contraction but no vaginal extrusion and no pain were reported. Eleven years before, she had a vaginal total hysterectomy for pelvic organ prolapse correction and one year before she had a vaginal prolapse repair using a synthetic mesh. A laparoscopic sacrocolpopexy with bilateral ooforectomy was performed. The second case is of a 54-year old patient (para 2, gravida 2) that presented stress urinary incontinence. On physical examination, the patient had a grade 3 uterine prolapse and grade 2 cystocele. Eleven years before she had a vaginal prolapse repair using a synthetic mesh and a miduretral sling for stress urinary incontinence. Two years before, she had the miduretal sling removed for recurrent urinary infections and dysuria. A laparoscopic sub-total hysterectomy with salpingectomy and ovarian conservation, sacrocolpopexy and a Burch colposuspension was performed. The procedures and postoperative recovery were uneventful. No minor or major complications occurred. The patients were discharged three days after surgery. Laparoscopic sacrocolpopexy is a promising approach for the treatment of recurrent pelvic organ prolapse after vaginal mesh surgery. It appears to be feasible, safe, and effective.

    2017-09-01

    Full Text Available BACKGROUND The present study was carried out at Government Medical College, Nagpur, to study the vaginal microbial flora in women using contraceptive measures. The lactobacillus dominant flora is a protective barrier against development of various microbial infections of vagina. The alteration of this protective mechanism is associated with an increased risk of bacterial vaginosis. The vaginal flora can be disrupted by a variety of factors like use of contraceptive measures, sexual intercourse, antimicrobial use and douching. The effects of specific contraceptive methods on the vaginal flora are not clear. The present study is therefore undertaken to study the vaginal microbial flora in contraceptive users. MATERIALS AND METHODS The vaginal swab was taken in all cases for detection of microbial flora in women who were using various contraceptive measures and nonusers. Isolation of organisms was done by using various bacteriological tests. The microbial data obtained in the two groups was compared. Student’s T-test was used for statistical analysis. RESULTS Gardnerella vaginalis, E. coli, Enterococci, group B streptococci and Candida spp were grown in the patients using oral contraceptives as well as copper-T. However, the growth of Gardnerella vaginalis (69.12%, group B streptococci (60% and Candida spp (58% was more in patients using copper-T while, growth of E. coli (51.72% and Enterococci (72.22% was more in patients using oral contraceptives. This difference in the growth of various organisms, however, was not significant. CONCLUSION It is concluded that the vaginal swab for microbial flora should be studied in all women using contraceptive measures. Presence of any abnormal microorganisms should alarm for immediate measures to control the infection and thus prevent establishment of vaginitis.

    Patients with vaginitis were classified into four groups: Group A (prepubertal under-aged females); Group B (pubertal under-aged females); Group C (reproductive age adult females); Group D (postmenopausal adult females). All vaginal specimens underwent microscopy, amine testing, Gram staining and culturing. Overall, 163 patients were included (33, 14, 81 and 35 patients, respectively). The most common infection was bacterial vaginosis (BV), followed by Ureaplasma infection, aerobic vaginitis (AV) and candidiasis. The most common AV-associated organism was Escherichia coli and the most common BV-associated organism was Gardnerella vaginalis. AV was more frequent in Group A, BV in Group C and Ureaplasma infections in Groups C/D. Decreased lactobacilli concentrations were associated with BV in fertile patients (Groups B-C). Although presentation of vaginitis is similar among females of different age in Greece, type and prevalence of pathogens differ. Normal vaginal flora changes are associated with higher risk of vaginitis in specific age groups. Impact Statement The worldwide incidence of reproductive tract infections has been increasing, with specific pathogens being associated with significant risk of morbidity and complications. However, literature data on the distribution of such infections in different age groups is limited. Therefore, the aim of this study was to provide data on the prevalence and causes of vaginitis in adult and non-adult females of all ages. This study has shown that although presentation of vaginitis is similar among females of different age groups and menstrual status in Greece, type and prevalence of responsible pathogens are different among groups. Changes in normal vaginal flora seem to be associated with higher risk of vaginitis in specific age-groups as well. These findings could contribute in adjusting diagnostic and therapeutic strategies for each age group according to the prevailing pathogens. Further research on antibiotic

    Emerging infections caused by fungi have become a widely recognized global phenomenon and are causing an increasing burden of disease. Genomic techniques are providing new insights into the structure of fungal populations, revealing hitherto undescribed fine-scale adaptations to environments and hosts that govern their emergence as infections. Cryptococcal meningitis is a neglected tropical disease that is responsible for a large proportion of AIDS-related deaths across Africa; however, the ecological determinants that underlie a patient's risk of infection remain largely unexplored. Here, we use genome sequencing and ecological genomics to decipher the evolutionary ecology of the aetiological agents of cryptococcal meningitis, Cryptococcus neoformans and Cryptococcus gattii, across the central African country of Zambia. We show that the occurrence of these two pathogens is differentially associated with biotic (macroecological) and abiotic (physical) factors across two key African ecoregions, Central Miombo woodlands and Zambezi Mopane woodlands. We show that speciation of Cryptococcus has resulted in adaptation to occupy different ecological niches, with C. neoformans found to occupy Zambezi Mopane woodlands and C. gattii primarily recovered from Central Miombo woodlands. Genome sequencing shows that C. neoformans causes 95% of human infections in this region, of which over three-quarters belonged to the globalized lineage VNI. We show that VNI infections are largely associated with urbanized populations in Zambia. Conversely, the majority of C. neoformans isolates recovered in the environment belong to the genetically diverse African-endemic lineage VNB, and we show hitherto unmapped levels of genomic diversity within this lineage. Our results reveal the complex evolutionary ecology that underpins the reservoirs of infection for this, and likely other, deadly pathogenic fungi. © 2016 The Authors.

    We report the resection of a vaginal septum while preserving the virginity of a 12-year-old girl with Herlyn-Werner-Wunderlich Syndrome (HWWS) having a didelphys uterus, obstructed hemivagina, and an ipsilateral renal agenesis with follow-up at 18 months. Successful resection of the vaginal septum with conservation of the hymenal ring and complete drainage of both the hematocolpos and the hematometra were achieved. Cyclic dysmenorrhea and pelvic pain were completely resolved on follow-up visits at 4, 6, and 18 months. Office hysteroscopy performed during the last follow-up visit revealed a patent vaginal vault without evidence of adenosis or recurrence of the vaginal septum. Vaginoscopy is a safe, convenient, and efficient diagnostic and therapeutic modality that can be used in the management of patients with an obstructed hemivagina. It maintains the patient's virginity and it is useful in patients with a restrictive vaginal opening or narrow vaginal canal. Furthermore, the hysteroscopic excision of the vaginal septum offers minimal risk of recurrence of the septal defect.

  19. Transfer of IgG in the female genital tract by MHC class I-related neonatal Fc receptor (FcRn) confers protective immunity to vaginal infection

    IgG is a major Ig subclass in mucosal secretions of the human female genital tract, where it predominates over the IgA isotype. Despite the abundance of IgG, surprisingly little is known about where and how IgG enters the lumen of the genital tract and the exact role local IgG plays in preventing sexually transmitted diseases. We demonstrate here that the neonatal Fc receptor, FcRn, is expressed in female genital tract epithelial cells of humans and mice and binds IgG in a pH-dependent manner. In vitro we show that FcRn mediates bidirectional IgG transport across polarized human endometrial HEC-1-A monolayers and primary human genital epithelial cells. Furthermore, endosomal acidification appears to be a prerequisite for FcRn-mediated IgG transcytosis; IgG transcytosis was demonstrated in vivo by translocation of systemically administered IgG into the genital lumen in WT but not FcRn-KO mice. The biological relevance of FcRn-transported IgG was demonstrated by passive immunization using herpes simplex virus-2 (HSV-2)–specific polyclonal serum, which conferred significantly higher protection against intravaginal challenge infection by the HSV-2 186 strain in WT mice than in FcRn-KO mice. These studies demonstrate that FcRn-mediated transport is a mechanism by which IgG can act locally in the female genital tract in immune surveillance and in host defense against sexually transmitted diseases.

    WHO and NACO recommend treatment of STIs/RTIs on the basis syndromic case management (SCM), even without laboratory confirmation, which may lead to over-treatment. Thus, this study was conducted to evaluate the utility of laboratory diagnosis for confirmation of patients with vaginal discharge diagnosed on the basis of SCM. 234 married women in reproductive age group, diagnosed as having vaginal discharge syndrome were included. Normal saline wet-mount slide preparations were made for detection of motile trichomonads. Gram stained smear were prepared and scored as per classification developed by Nugent. The presence of pseudohyphae and/or budding yeast cells was considered diagnostic of candidal infection. VDRL, TPHA and HIV testing were also done as per protocol. The median age of the study population was 34 years. Most common cause was bacterial vaginosis (positive= 21.4%, 95% CI= 16.6-27.1%; intermediate score= 17.5%, 95% CI= 13.2-22.9%), followed by candidiasis (13.7%, 95% CI= 98-18.7%) and trichomoniasis (0.4%, 95% CI= 0-2.6%). No etiological diagnosis for vaginal discharge could be established in approximately half of the women. Only two women were HIV positive; one was reactive by VDRL and TPHA tests. Our study highlights the possible lacunae in SCM. Large number of patients may be over-treated if only syndromic management is followed, with financial, medical and social implications. Thus we recommend, the treatment maybe initiated on the basis of SCM, but it is essential that laboratory diagnosis is sought for and the treatment modified accordingly.

    Full Text Available Introduction: The vaginal flora is a dynamic ecosystem that can be easily altered. Although, there are four causes of vaginal discharges which cover almost 95% of vaginaitis. Candidal Vaginaitis is an infection of the vagina’s mucous membranes by Candida albicans (CA. Present study attempted to Candidal Vaginitis in women referred to health centers in Yazd and the role of innate & cell-mediated immunity against Candidal Vaginitis. Materials and Methods: A cross-sectional study conducted from September 2011 to September 2012 in Yazd city. A total of 360 women were recruited. The collection of material for diagnosis is ideally performed during a comprehensive pelvic examination using a speculum for diagnosis of CA with identify vaginal pH; smear preparing and staining and culturing. Results: Finally all of 360 women that observed and tested, 120 (33.33% of them have involved and 240 (66.67% have not involved. from 120 infected women, 55paitents had Bacterial vaginosis (15.6% 40 patients had Ca (10.8% and 25 patients had Trichomonas vaginalis (5.9%. Despite the role for cell-mediated immunity in host protection against the majority of mucosal CA infections, studied has been in women with recurrent vaginitis, in HIV-infected women. Thus, current investigations have been focused specifically on innate and acquired immune responses against CA at the vaginal mucosa instead of Vulvovaginal Candidiasis being caused by defective or dysfunctional CD4+ T helper 1-type cell-mediated immune reactivity. Conclusion: Strongly suggest that distinct vaginal lymphocyte subsets participate in the adaptive anti-Candida immunity at the vaginal level, with the vaginal CD4_ T cells probably playing a major role.

    Vaginal discharge is a commonest complaint among women in reproductive age group. Infective vaginal discharge can be broadly categorized into vaginitis or mucopurulent cervicitis. Vaginitis is predominantly caused by bacterial vaginosis, vaginal candidiasis, vaginal trichomoniasis, etc. Mucopurulent cervicitis is due to chlamydia or gonococcal infection. The targeted management is based on identification of causative organism and targeting the therapy against it, while syndromic management is based on high risk factors's presence. To study the effect of targeted management as compared to syndromic management in achieving a complete cure for abnormal vaginal discharge and to study the microbial flora of women presenting with abnormal vaginal discharge. The study is a randomized control trial conducted at tertiary health care on 200 women who presented with abnormal vaginal discharge, distributed in two groups A and B each consisted of 100 women. Group A underwent laboratory investigations, and treatment was started as soon as reports were available. Group B was given syndromic management based on high risk factors's presence. Both groups were followed up after 2 weeks. The prevalence of various organisms in vaginal discharge was candidiasis 39 %, bacterial vaginosis 28 %, trichomoniasis 5 %, N. gonorrhoeae 5 % and chlamydia 2 % among the 100 women in group A. Response to treatment for vaginitis was 76.3 % in group A, whereas it was 41 % in group B. With cervicitis, 71.4 % women responded to treatment in targeted group as compared to 54 % in syndromic management group. There is a potential disadvantage of syndromic management because of its total reliability on a subjective clinical assessment.

    Full Text Available Abstract Background The vaginal microflora is important for maintaining vaginal health and preventing infections of the reproductive tract. The rectum has been suggested as the major source for the colonisation of the vaginal econiche. Methods To establish whether the rectum can serve as a possible bacterial reservoir for colonisation of the vaginal econiche, we cultured vaginal and rectal specimens from pregnant women at 35-37 weeks of gestation, identified the isolates to the species level with tRNA intergenic length polymorphism analysis (tDNA-PCR and genotyped the isolates for those subjects from which the same species was isolated simultaneously vaginally and rectally, by RAPD-analysis. One vaginal and one rectal swab were collected from a total of each of 132 pregnant women at 35-37 weeks of gestation. Swabs were cultured on Columbia CNA agar and MRS agar. For each subject 4 colonies were selected for each of both sites, i.e. 8 colonies in total. Results Among the 844 isolates that could be identified by tDNA-PCR, a total of 63 bacterial species were present, 9 (14% only vaginally, 26 (41% only rectally, and 28 (44% in both vagina and rectum. A total of 121 (91.6% of 132 vaginal samples and 51 (38.6% of 132 rectal samples were positive for lactobacilli. L. crispatus was the most frequently isolated Lactobacillus species from the vagina (40% of the subjects were positive, followed by L. jensenii (32%, L. gasseri (30% and L. iners (11%. L. gasseri was the most frequently isolated Lactobacillus species from the rectum (15%, followed by L. jensenii (12%, L. crispatus (11% and L. iners (2%. A total of 47 pregnant women carried the same species vaginally and rectally. This resulted in 50 vaginal/rectal pairs of the same species, for a total of eight different species. For 34 of the 50 species pairs (68%, isolates with the same genotype were present vaginally and rectally and a high level of genotypic diversity within species per subject was also

    Vaginal semisolid products are frequently used to treat vaginal infections and atrophy-related symptoms of menopause. Formulations composition and the methods for their characterization, especially those developed concerning the target epithelia, are key tools to predict in vivo results at early stages of product development. However, recent studies on this subject have been almost exclusively focused on anti-HIV preparations. The aim of this work consists on improving traditional characterization methods by using physiological parameters in order to construct predictive tools to characterize a new ideal vaginal semisolid formulation whatever target it may have. Ten vaginal antimicrobial and hormonal products already available in the market were studied (Gino-Canesten®, Sertopic®, Dermofix®, Gyno-pevaryl®, Lomexin®, Gino Travogen®, Dalacin V®, Ovestin®, Blissel®, Colpotrophine®). Furthermore, Universal Placebo gel and Replens® were used for comparison. Products were characterized in terms of: pH and buffering capacity in a vaginal fluid simulant (VFS); osmolality - directly and upon dilution in VFS; textural parameters (firmness, adhesiveness and bioadhesion) using vaginal ex vivo porcine epithelium; and viscosity (including VFS dilution at 37°C and after administration on an ex vivo model). Interestingly, the majority of the tested commercial vaginal formulations did not present technological characteristics close to the ideal ones when tested under target biological conditions. The inclusion of such methodologic adaptations is expected to optimize cost-efficiency of new formulations development by predicting efficacy and safety profiles at early stages of product development.

    Full Text Available In previous studies it was shown that Pichia guilliermondii strain Z1, isolated from healthy Moroccan citrus Valencia-Late oranges, was effective against Penicillium italicum. Here the effectiveness of strain Z1 was assessed against Penicillium digitatum, the causal agent of green mould, under different temperature (5-25°C and relative humidity (RH (45-100% regimes for its reliable and largescale application in packinghouse. All main effects and interactions were significant (P80%. Its applications as a formulated product significantly reduced the incidence of infected fruit (55% and the percentage of infected wounds (47% compared to the only pathogen control treatment. However, disease control with formulated product was significantly less than that obtained with thiabendazole (30% or strain Z1 culturable cells (35%. These results highlight that strain Z1 is an effective biological control agent for control of green mould under varying environmental conditions, and control may be optimized by combining its use with other environmentally-safe post-harvest treatments or improved formulation.

    Trichomonas vaginalis causes vaginitis and increases the risk of HIV transmission by heterosexual sex, while Tritrichomonas foetus causes premature abortion in cattle. Our goals were to determine the effects, if any, of anti-retroviral lectins, which are designed to prevent heterosexual transmission of HIV, on adherence of Trichomonas to ectocervical cells and on Tritrichomonas infections in a mouse model. We show that Trichomonas Asn-linked glycans (N-glycans), like those of HIV, bind the mannose-binding lectin (MBL) that is part of the innate immune system. N-glycans of Trichomonas and Tritrichomonas bind anti-retroviral lectins (cyanovirin-N and griffithsin) and the 2G12 monoclonal antibody, each of which binds HIV N-glycans. Binding of cyanovirin-N appears to be independent of susceptibility to metronidazole, the major drug used to treat Trichomonas. Anti-retroviral lectins, MBL, and galectin-1 cause Trichomonas to self-aggregate and precipitate. The anti-retroviral lectins also increase adherence of ricin-resistant mutants, which are less adherent than parent cells, to ectocervical cell monolayers and to organotypic EpiVaginal tissue cells. Topical application of either anti-retroviral lectins or yeast N-glycans decreases by 40 to 70% the recovery of Tritrichomonas from the mouse vagina. These results, which are explained by a few simple models, suggest that the anti-retroviral lectins have a modest potential for preventing or treating human infections with Trichomonas.

    2011-03-01

    Vaginal atrophy, which is associated with vaginal itching, burning, dryness, irritation, and pain, is estimated to affect up to 40% of postmenopausal women. Estrogens play a key role in maintaining vaginal health; women with low serum estradiol are more likely to experience vaginal dryness, dyspareunia, and reduced sexual activity compared with women who have higher estradiol levels. The purpose of this review is to assess the prevalence and impact of dyspareunia, a symptom of vaginal atrophy, on the health of postmenopausal women and to evaluate treatment options using vaginal estrogens (U.S. Food and Drug Administration [FDA] approved). Relevant published literature was identified by searching Index Medicus using the PubMed online database. The search terms dyspareunia, vaginal estrogen, vaginal hormone therapy, vaginal atrophy, and atrophic vaginitis were the focus of the literature review. Current treatment guidelines for vaginal atrophy recommend the use of minimally absorbed local vaginal estrogens, along with non-hormonal lubricants or moisturizers, coupled with maintenance of sexual activity. Vaginal estrogen therapy has been shown to provide improvement in the signs and symptoms of vaginal or vulvar atrophy. Vaginal tablets, rings, and creams are indicated for the treatment of vaginal atrophy, and the FDA has recently approved a low-dose regimen of conjugated estrogens cream to treat moderate-to-severe postmenopausal dyspareunia. The use of low-dose vaginal estrogens has been shown to be effective in treating symptoms of vaginal atrophy without causing significant proliferation of the endometrial lining, and no significant differences have been seen among vaginal preparations in terms of endometrial safety. Women should be informed of the potential benefits and risks of the treatment options available, and with the help of their healthcare provider, choose an intervention that is most suitable to their individual needs and circumstances. © 2010

    Full Text Available Candidiasis is the second most common vaginal infection. Given the frequent recurrence of the disease, many women tend to use herbal remedies. Thus, the present study aimed to review the association between vaginal candidiasis and herbal medicines in Iran. In this review, we retrieved articles published from 2001 to 2016. Then, the results were expressed both quantitatively and qualitatively. In this study, nine articles were reviewed, which had investigated thyme, garlic, garlic-thyme, olive oil, propolis, myrtus, Nigella sativa (black cumin, and Bunium perscicum boiss (black zira. Subsequently, each of these plants was thoroughly dealt with. The studies on black cumin, garlic, and thyme reported positive effects for these herbs, and they were widely produced for therapeutic purposes. In addition, myrtus was found to have a salutary impact on vaginal candidiasis.

    Full Text Available The bacterial biota of the human vagina can have a profound impact on the health of women and their neonates. Changes in the vaginal microbiota have been associated with several adverse health outcomes including premature birth, pelvic inflammatory disease, and acquisition of HIV infection. Cultivation-independent molecular methods have provided new insights regarding bacterial diversity in this important niche, particularly in women with the common condition bacterial vaginosis (BV. PCR methods have shown that women with BV have complex communities of vaginal bacteria that include many fastidious species, particularly from the phyla Bacteroidetes and Actinobacteria. Healthy women are mostly colonized with lactobacilli such as Lactobacillus crispatus, Lactobacillus jensenii, and Lactobacillus iners, though a variety of other bacteria may be present. The microbiology of BV is heterogeneous. The presence of Gardnerella vaginalis and Atopobium vaginae coating the vaginal epithelium in some subjects with BV suggests that biofilms may contribute to this condition.

    The cases which have been presented here have varied presentations but all the three patients in the series had acyclical abdominal pain. Since the uterus is functional there is collection of blood in the pouch formed due to the vaginal septum. This is a potential site for infection and could result in foul smelling discharge. Failure of fusion of lower ends of mullerian ducts that form vagina results in longitudinal vaginal septum. The septum may be partial or complete. The clinical syndrome of double uterus with vaginal obstruction (unilateral, partial or complete) and ipsilateral renal agenesis (same as of the side of obstruction) is rare. This combination is suggestive of embryologic arrest occuring at 8 weeks of pregnancy that simultaneausly affected the mullerian and metanephric ducts.

    Full Text Available Extraperitoneal cesarean section was once used for the prevention of infection and postoperative adhesion. However, we report an unusual complication after this procedure. A 29-year-old woman had pus discharge from the anterior vaginal wall after extraperitoneal cesarean section. Broad-spectrum antibiotics failed to relieve her symptoms and vaginal culture yielded Morganella morganii. Magnetic resonance imaging, sagittal view, showed a cervical abscess measuring 5 × 5 cm with a tract extending to the anterior vagina. After performing dilation and abscess drainage via the cervical ostium, the symptoms gradually subsided with adequate antibiotic treatment. Cervical abscess may develop after extraperitoneal cesarean section and present initially as vaginal fistula. Detailed imaging study provides comprehensive anatomic information for effective management.

    Vaginal lactobacilli offer protection against recurrent urinary infections, bacterial vaginosis, and vaginal candidiasis. To characterise the isolated vaginal lactobacilli strains for their probiotic properties and to compare their probiotic potential. The Lactobacillus strains were isolated from vaginal samples by conventional culturing and identified by sequencing of the 16S rDNA fragment. Several functional properties were detected (production of hydrogen peroxide and lactic acid; antagonistic activity against Escherichia coli, Candida albicans, Candida glabrata, and Gardnerella vaginalis; auto-aggregation and adhesiveness) as well as safety (haemolytic activity, antibiotic susceptibility, presence of transferrable resistance genes). A total of 135 vaginal lactobacilli strains of three species, Lactobacillus crispatus (56%), Lactobacillus jensenii (26%), and Lactobacillus gasseri (18%) were characterised using several functional and safety tests. Most of L. crispatus (89%) and L. jensenii (86%) strains produced H2O2. The best lactic acid producers were L. gasseri (18.2±2.2 mg/ml) compared to L. crispatus (15.6±2.8 mg/ml) and L. jensenii (11.6±2.6 mg/ml) (pjensenii. L. gasseri strains expressed significantly lower anticandidal activity compared to L. crispatus and L. jensenii (pjensenii; therefore; a potential probiotic candidate could be found among L. crispatus strains.

  16. Potential Use of Antimicrobial Peptides as Vaginal Spermicides/Microbicides

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available The concurrent increases in global population and sexually transmitted infection (STI demand a search for agents with dual spermicidal and microbicidal properties for topical vaginal application. Previous attempts to develop the surfactant spermicide, nonoxynol-9 (N-9, into a vaginal microbicide were unsuccessful largely due to its inefficiency to kill microbes. Furthermore, N-9 causes damage to the vaginal epithelium, thus accelerating microbes to enter the women’s body. For this reason, antimicrobial peptides (AMPs, naturally secreted by all forms of life as part of innate immunity, deserve evaluation for their potential spermicidal effects. To date, twelve spermicidal AMPs have been described including LL-37, magainin 2 and nisin A. Human cathelicidin LL-37 is the most promising spermicidal AMP to be further developed for vaginal use for the following reasons. First, it is a human AMP naturally produced in the vagina after intercourse. Second, LL-37 exerts microbicidal effects to numerous microbes including those that cause STI. Third, its cytotoxicity is selective to sperm and not to the female reproductive tract. Furthermore, the spermicidal effects of LL-37 have been demonstrated in vivo in mice. Therefore, the availability of LL-37 as a vaginal spermicide/microbicide will empower women for self-protection against unwanted pregnancies and STI.

    To review the safety and efficacy of anterior vaginal compartment pelvic organ prolapse surgery. Every 4 years and as part of the Fifth International Collaboration on Incontinence we reviewed the English-language scientific literature after searching PubMed, Medline, Cochrane library and the Cochrane database of systematic reviews, published up to January 2012. Publications were classified as level 1 evidence (randomised controlled trials [RCT] or systematic reviews), level 2 (poor quality RCT, prospective cohort studies), level 3 (case series or retrospective studies) and level 4 case reports. The highest level of evidence was utilised by the committee to make evidence-based recommendations based upon the Oxford grading system. A grade A recommendation usually depends on consistent level 1 evidence. A grade B recommendation usually depends on consistent level 2 and/or 3 studies, or "majority evidence" from RCTs. A grade C recommendation usually depends on level studies or "majority evidence" from level 2/3 studies or Delphi processed expert opinion. A grade D "no recommendation possible" would be used where the evidence is inadequate or conflicting and when expert opinion is delivered without a formal analytical process, such as by Delphi. Absorbable mesh augmentation of anterior compartment native tissue repair improves the anatomical outcome compared with native tissue repair alone with no increased complication rate in meta-analysis of 2 RCTS (grade B). Biological grafts in meta-analysis have improved anatomical outcomes with no change in subjective outcomes compared with native tissue repairs (grade B). There is conflicting level 1 evidence to support porcine dermis and a single RCT to support small intestine submucosa as graft agents in anterior compartment prolapse surgery (grade B). Consistent level 1 data support a superior anatomical outcome for polypropylene mesh compared with a biological graft in the anterior compartment. Mesh exposure rate was

    Full Text Available Abstract Background Study of in vivo antifungal activity of the hydroalcoholic extract (HE and n-BuOH extract (BUTE of Sapindus saponaria against azole-susceptible and -resistant human vaginal Candida spp. Methods The in vitro antifungal activity of HE, BUTE, fluconazole (FLU, and itraconazole (ITRA was determined by the broth microdilution method. We obtained values of minimal inhibitory concentration (MIC and minimum fungicide concentration (MFC for 46 strains of C. albicans and 10 of C. glabrata isolated from patients with vulvovaginal candidiasis (VVC. VVC was induced in hyperestrogenic Wistar rats with azole-susceptible C. albicans (SCA, azole-resistant C. albicans (RCA, and azole-resistant C. glabrata (RCG. The rats were treated intravaginally with 0.1 mL of HE or BUTE at concentrations of 1%, 2.5% and 5%; 100 μg/mL of FLU (treatment positive control; or distilled water (negative control at 1, 24, and 48 h after induction of the infection, and the progress of VVC was monitored by culturing and scanning electron microscopy (SEM. The toxicity was evaluated in cervical cells of the HeLa cell line. Results The extracts showed in vitro inhibitory and fungicidal activity against all the isolates, and the MIC and MFC values for the C. glabrata isolates were slightly higher. In vivo, the SCA, RCA, and RCG infections were eliminated by 21 days post-infection, with up to 5% HE and BUTE, comparable to the activity of FLU. No cytotoxic action was observed for either extract. Conclusions Our results demonstrated that HE and BUTE from S. saponaria show inhibitory and fungicidal activity in vitro, in addition to in vivo activity against azole-resistant vaginal isolates of C. glabrata and azole-susceptible and resistant isolates of C. albicans. Also considering the lack of cytotoxicity and the low concentrations of the extracts necessary to eliminate the infection in vivo, HE and BUTE show promise for continued studies with purified antifungal substances

    Full Text Available Candida is a normal commensal that takes the role of a pathogen under compromised conditions. Increased longevity of human life and immunocompromised conditions together paves the way for the increase in opportunistic infections like candidiasis. Vulvovaginal candidiasis (VVC is the second most common cause of vaginal discharge next to Chlamydia.1 VVC is the leading cause of abnormal vaginal discharge due to microbial causes. Untreated VVC is a possible risk factor for acquisition of HIV.2 Prevention of sexually transmitted infections (STIs including VVC can reduce the transmission of HIV since STIs and HIV have the common mode of transmission and one enhances the risk of infection with the other. Early diagnosis and treatment of candidiasis can reduce the pregnancy related morbidity

  1. Contraceptive vaginal rings: a review.

    Science.gov (United States)

    Brache, Vivian; Faundes, Anibal

    2010-11-01

    Development efforts on contraceptive vaginal rings were initiated over 40 years ago based on two principles: the capacity of the vaginal epithelium to absorb steroids and the capacity of elastomers to release these hormones at a nearly constant rate. Numerous models of contraceptive vaginal rings (CVRs) have been studied, but only two have reached the market: NuvaRing, a combined ring that releases etonogestrel (ENG) and ethinylestradiol (EE), and Progering, a progesterone-releasing ring for use in lactating women. The main advantages of CVRs are their effectiveness (similar to or slightly better than the pill), ease of use without the need of remembering a daily routine, user's ability to control initiation and discontinuation, nearly constant release rate allowing for lower doses, greater bioavailability and good cycle control with the combined ring. The main disadvantages are related to the mode of delivery; CVRs may cause vaginal discharge and complaints, ring expulsion is not uncommon, the ring may be felt during coitus and vaginal insertion may be unpleasant for some women. The studies reviewed in this article provide evidence that CVRs are safe, effective and highly acceptable to women. There is no doubt that CVRs offer a new, effective contraceptive option to women, expanding their available choices of hormonal contraception. Copyright © 2010 Elsevier Inc. All rights reserved.

  2. Developmental Origin of Vaginal Epithelium

    2010-01-01

    The developmental origin of vaginal epithelium has been controversial for nearly a century, with speculation that vaginal epithelium originates from the Müllerian duct, Wolffian duct, and/or urogenital sinus. None of these possibilities has been definitively proven or disproven by direct scientific data. To define precisely the origin of vaginal epithelium, epithelial cells of the Müllerian duct, Wolffian duct, or urogenital sinus were fluorescently labeled in mouse embryos by crossing tdTomato-EGFP dual-reporter transgenic mice with transgenic mouse lines that express Cre recombinase in each type of epithelium. In embryos and newborn mice, the vagina consisted of fused Müllerian ducts plus the sinus vagina of urogenital sinus origin. However, the proportion of the sinus vagina was significantly reduced as the Müllerian vagina grew caudally. By postpartum day 7, the Müllerian vagina extended to the caudal end of the body, whereas the sinus vagina remained only at the junction between the vagina and perineal skin. As the vagina opened in puberty, urogenital sinus epithelium was detected only in the vulva, but not in the vagina. Additionally, from embryo to adult stages, residual Wolffian duct epithelium was present in the dorsolateral stromal wall of the vagina, but not within vaginal or vulvar epithelium. In conclusion, adult mouse vaginal epithelium is derived solely from Müllerian duct epithelium. PMID:20638775

    Recent iPrEx clinical trial results provided evidence that systemic preexposure prophylaxis (PrEP) with emtricitabine (FTC) and tenofovir disoproxil fumarate (TDF) can partially prevent rectal HIV transmission in humans. Similarly, we have previously demonstrated that systemic administration of the same FTC-TDF combination efficiently prevented rectal transmission in humanized bone marrow/liver/thymus (BLT) mice. The CAPRISA 004 trial recently demonstrated that topical application of the tenofovir could partially prevent vaginal HIV-1 transmission in humans. To further validate the usefulness of the BLT mouse model for testing HIV prevention strategies, we evaluated the topical administration of tenofovir as used in CAPRISA 004 to prevent vaginal HIV transmission in BLT mice. Our results demonstrate that vaginally administered 1% tenofovir significantly reduced HIV transmission in BLT mice (P = 0.002). Together with the results obtained after systemic antiretroviral PrEP, these topical inhibitor data serve to validate the use of humanized BLT mice to evaluate both systemic and topical inhibitors of HIV transmission. Based on these observations, we tested six additional microbicide candidates for their ability to prevent vaginal HIV transmission: a C-peptide fusion inhibitor (C52L), a membrane-disrupting amphipathic peptide inhibitor (C5A), a trimeric d-peptide fusion inhibitor (PIE12-Trimer), a combination of reverse transcriptase inhibitors (FTC-TDF), a thioester zinc finger inhibitor (TC247), and a small-molecule Rac inhibitor (NSC23766). No protection was seen with the Rac inhibitor NSC23766. The thioester compound TC247 offered partial protection. Significant protection was afforded by FTC-TDF, and complete protection was offered by three different peptide inhibitors tested. Our results demonstrate that these effective topical inhibitors have excellent potential to prevent vaginal HIV transmission in humans.

    Antibiotics may induce alterations in the commensal microbiota of the birth canal in pregnant women. Therefore, we studied the effect of antibiotic administration during pregnancy on commensal vaginal bacterial colonization at gestational week 36. Six hundred and sixty-eight pregnant women from the novel unselected Copenhagen Prospective Studies on Asthma in Childhood (COPSAC2010 ) pregnancy cohort participated in this analysis. Detailed information on oral antibiotic prescriptions during pregnancy filled at the pharmacy was obtained and verified prospectively. Vaginal samples were obtained at pregnancy week 36 and cultured for bacteria. Women who received oral antibiotics during any pregnancy trimester had an increased rate of colonization by Staphylococcus species in the vaginal samples as compared with samples obtained from women without any antibiotic treatment during pregnancy (adjusted OR 1.63, 95% CI 1.06-2.52, p 0.028). Oral antibiotic administration in the third trimester were also associated with increased colonization by Staphylococcus species (adjusted OR 1.98, 95% CI 1.04-3.76, p 0.037). These bacteriological changes were associated with urinary tract infection antibiotics. Women treated in the third trimester of pregnancy were more often colonized by Escherichia coli than women without antibiotic treatment in the third trimester (adjusted OR 1.91, 95% CI 1.04-3.52, p 0.038). This change was associated with respiratory tract infection (RTI) antibiotics. We did not observe any significant changes in vaginal Streptococcus agalactiae (group B streptoccocus) or Staphylococcus aureus colonization following antibiotic treatment in pregnancy. Antibiotic administration during pregnancy leads to alterations in the vaginal microbiological ecology prior to birth, with potential morbidity, and long-term effects on the early microbial colonization of the neonate. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical

    Vaginal HIV-1 shedding has been associated with Trichomonas vaginalis (TV) infection and could play a role in HIV transmission. The purpose of the study was to examine if effective TV treatment reduces the presence of vaginal HIV-1 RNA. TV+ women attending an HIV outpatient clinic in New Orleans, LA, who resolved infection (n = 58) and TV-negative controls (n = 92), matched on antiretroviral therapy (ART) were examined and interviewed at baseline, 1, and 3 months. TV status was tested by culture and the amount of cell free HIV-1 RNA in the vaginal fluids was determined by the Amplicor HIV-1 Monitor ultrasensitive assay. : Most women (81.3%) were black and the mean age was 37.5 (SD 8.7). At baseline, 46.0% had plasma HIV-1 RNA >/=10,000 copies/mL, 26.4% had CD4<200 cells/muL, 54.7% were taking ART, and only 26.0% had detectable HIV-1 RNA in their vaginal fluids. TV-positive women who were effectively treated for TV were less likely to shed HIV vaginally at 3-months post-treatment compared to baseline (R.R. 0.34, 95% CI: 0.12-0.92, P = 0.03), whereas there was no change for TV-negative women. This study provides additional support that reducing TV infection among HIV-positive women may have an impact on the prevention of HIV transmission. Reasons for the delayed treatment effect and the effect on cervical shedding need further investigation.

    Bacterial vaginosis increases the susceptibility to sexually transmitted infections and negatively affects women's reproductive health. To investigate host-vaginal microbiota interactions and the impact on immune barrier function, we colonized 3-dimensional (3-D) human vaginal epithelial cells with 2 predominant species of vaginal microbiota (Lactobacillus iners and Lactobacillus crispatus) or 2 prevalent bacteria associated with bacterial vaginosis (Atopobium vaginae and Prevotella bivia). Colonization of 3-D vaginal epithelial cell aggregates with vaginal microbiota was observed with direct attachment to host cell surface with no cytotoxicity. A. vaginae infection yielded increased expression membrane-associated mucins and evoked a robust proinflammatory, immune response in 3-D vaginal epithelial cells (ie, expression of CCL20, hBD-2, interleukin 1β, interleukin 6, interleukin 8, and tumor necrosis factor α) that can negatively affect barrier function. However, P. bivia and L. crispatus did not significantly upregulate pattern-recognition receptor-signaling, mucin expression, antimicrobial peptides/defensins, or proinflammatory cytokines in 3-D vaginal epithelial cell aggregates. Notably, L. iners induced pattern-recognition receptor-signaling activity, but no change was observed in mucin expression or secretion of interleukin 6 and interleukin 8. We identified unique species-specific immune signatures from vaginal epithelial cells elicited by colonization with commensal and bacterial vaginosis-associated bacteria. A. vaginae elicited a signature that is consistent with significant disruption of immune barrier properties, potentially resulting in enhanced susceptibility to sexually transmitted infections during bacterial vaginosis. © The Author 2014.

    The human vaginal microbiome plays a critical but poorly defined role in reproductive health. Vaginal microbiome alterations are associated with increased susceptibility to sexually-transmitted infections (STI) possibly due to related changes in innate defense responses from epithelial cells. Study of the impact of commensal bacteria on the vaginal mucosal surface has been hindered by current vaginal epithelial cell (VEC) culture systems that lack an appropriate interface between the apical surface of stratified squamous epithelium and the air-filled vaginal lumen. Therefore we developed a reproducible multilayer VEC culture system with an apical (luminal) air-interface that supported colonization with selected commensal bacteria. Multilayer VEC developed tight-junctions and other hallmarks of the vaginal mucosa including predictable proinflammatory cytokine secretion following TLR stimulation. Colonization of multilayers by common vaginal commensals including Lactobacillus crispatus, L. jensenii, and L. rhamnosus led to intimate associations with the VEC exclusively on the apical surface. Vaginal commensals did not trigger cytokine secretion but Staphylococcus epidermidis, a skin commensal, was inflammatory. Lactobacilli reduced cytokine secretion in an isolate-specific fashion following TLR stimulation. This tempering of inflammation offers a potential explanation for increased susceptibility to STI in the absence of common commensals and has implications for testing of potential STI preventatives.

    Vaginal probiotics containing lactic acid bacteria with activity towards pathogenic microorganisms that cause urogenital tract infections have been proposed as a valid strategy for their prophylaxis and therapy. A murine experimental model was set up to evaluate the colonization capability of beneficial human lactobacilli and their effects on the mouse vaginal mucosa and innate immune cells. Five Lactobacillus strains were intravaginally inoculated into previously estrogenized BALB/c mice. The significance of the effects observed in the vaginal tract was determined by analysis of variance using the general linear model. The numbers of viable vaginal lactobacilli were significantly higher at proestrous-estrous than those at the metaestrous-diestrous phase and decreased markedly on the days after inoculation. Lactobacilli inoculation did not cause cytological or histological modifications of the murine vaginal tract. Moreover, the intravaginal administration of Lactobacillus salivarius CRL (Centro de Referencia para Lactobacilos culture collection) 1328 and Lactobacillus gasseri CRL 1263 did not affect the amounts of granulocytes and macrophages present in vaginal washings. In conclusion, the results demonstrate that vaginal lactobacilli did not produce adverse effects on the murine vaginal tract. Therefore, they could be proposed as safe probiotic candidates to promote a balanced microbiota in the urogenital tract.

    Mucosal epithelia use osmotic gradients for fluid absorption and secretion. We hypothesized that administration of hypotonic solutions would induce fluid uptake that could be advantageous for rapidly delivering drugs through mucus to the vaginal epithelium. We found that hypotonic formulations markedly increased the rate at which small molecule drugs and mucoinert nanoparticles (mucus-penetrating particles, or MPP), but not conventional mucoadhesive nanoparticles (CP), reached the vaginal epithelial surface in vivo in mice. Additionally, hypotonic formulations greatly enhanced drug and MPP delivery to the entire epithelial surface, including deep into the vaginal folds (rugae) that drugs or MPP in isotonic formulations failed to reach efficiently. However, hypotonic formulations caused unencapsulated "free" drugs to be drawn through the epithelium, reducing vaginal retention. In contrast, hypotonic formulations caused MPP to accumulate rapidly and uniformly on vaginal surfaces, ideally positioned for localized sustained drug delivery. Using a mouse model of vaginal genital herpes (HSV-2) infection, we found that hypotonic delivery of free drug led to improved immediate protection, but diminished longer-term protection. In contrast, as we previously demonstrated, hypotonic delivery of drug via MPP led to better long-term retention and protection in the vagina. Importantly, we demonstrate that slightly hypotonic formulations provided rapid and uniform delivery of MPP to the entire vaginal surface, thus enabling formulations with minimal risk of epithelial toxicity. Hypotonic formulations for vaginal drug delivery via MPP may significantly improve prevention and treatment of reproductive tract diseases and disorders. Copyright © 2013 Elsevier Ltd.

    Zika virus (ZIKV) is a mosquito-transmitted virus that can cause severe defects in an infected fetus. ZIKV is also transmitted by sexual contact, although the relative importance of sexual transmission is unclear. To better understand the role of sexual transmission in ZIKV pathogenesis, a nonhuman primate (NHP) model of vaginal transmission was developed. ZIKV was readily transmitted to mature cycling female rhesus macaque (RM) by vaginal inoculation with 104–106 plaque-forming units (PFU). However, there was variability in susceptibility between the individual RM with 1–>8 vaginal inoculations required to establish infection. After treatment with Depoprovera, a widely used contraceptive progestin, two RM that initially resisted 8 vaginal ZIKV inoculations became infected after one ZIKV inoculation. Thus, Depoprovera seemed to enhance susceptibility to vaginal ZIKV transmission. Unexpectedly, the kinetics of virus replication and dissemination after intravaginal ZIKV inoculation were markedly different from RM infected with ZIKV by subcutaneous (SQ) virus inoculation. Several groups have reported that after SQ ZIKV inoculation vRNA is rapidly detected in blood plasma with vRNA less common in urine and saliva and only rarely detected in female reproductive tract (FRT) secretions. In contrast, in vaginally inoculated RM, plasma vRNA is delayed for several days and ZIKV replication in, and vRNA shedding from, the FRT was found in all 6 animals. Further, after intravaginal transmission ZIKV RNA shedding from FRT secretions was detected before or simultaneously with plasma vRNA, and persisted for at least as long. Thus, ZIKV replication in the FRT was independent of, and often preceded virus replication in the tissues contributing to plasma vRNA. These results support the conclusion that ZIKV preferentially replicates in the FRT after vaginal transmission, but not after SQ transmission, and raise the possibility that there is enhanced fetal infection and pathology

    Streptococcus agalactiae (group B streptococcus [GBS]) colonizes the rectovaginal tract in 20% to 30% of women and during pregnancy can be transmitted to the newborn, causing severe invasive disease. Current routine screening and antibiotic prophylaxis have fallen short of complete prevention of GBS transmission, and GBS remains a leading cause of neonatal infection. We have investigated the ability of Streptococcus salivarius, a predominant member of the native human oral microbiota, to control GBS colonization. Comparison of the antibacterial activities of multiple S. salivarius strains by use of a deferred-antagonism test showed that S. salivarius strain K12 exhibited the broadest spectrum of activity against GBS. K12 effectively inhibited all GBS strains tested, including disease-implicated isolates from newborns and colonizing isolates from the vaginal tract of pregnant women. Inhibition was dependent on the presence of megaplasmid pSsal-K12, which encodes the bacteriocins salivaricin A and salivaricin B; however, in coculture experiments, GBS growth was impeded by K12 independently of the megaplasmid. We also demonstrated that K12 adheres to and invades human vaginal epithelial cells at levels comparable to GBS. Inhibitory activity of K12 was examined in vivo using a mouse model of GBS vaginal colonization. Mice colonized with GBS were treated vaginally with K12. K12 administration significantly reduced GBS vaginal colonization in comparison to nontreated controls, and this effect was partially dependent on the K12 megaplasmid. Our results suggest that K12 may have potential as a preventative therapy to control GBS vaginal colonization and thereby prevent its transmission to the neonate during pregnancy.

    Full Text Available Background: Over-the-counter (OTC feminine hygiene products come with little warning about possible side effects. This study evaluates in-vitro their effects on Lactobacillus crispatus, which is dominant in the normal vaginal microbiota and helps maintain a healthy mucosal barrier essential for normal reproductive function and prevention of sexually transmitted infections and gynecologic cancer. Methods: A feminine moisturizer (Vagisil, personal lubricant, and douche were purchased OTC. A topical spermicide (nonoxynol-9 known to alter the vaginal immune barrier was used as a control. L. crispatus was incubated with each product for 2 and 24h and then seeded on agar for colony forming units (CFU. Human vaginal epithelial cells were exposed to products in the presence or absence of L. crispatus for 24h, followed by epithelium-associated CFU enumeration. Interleukin-8 was immunoassayed and ANOVA was used for statistical evaluation. Results: Nonoxynol-9 and Vagisil suppressed Lactobacillus growth at 2h and killed all bacteria at 24h. The lubricant decreased bacterial growth insignificantly at 2h but killed all at 24h. The douche did not have a significant effect. At full strength, all products suppressed epithelial viability and all, except the douche, suppressed epithelial-associated CFU. When applied at non-toxic dose in the absence of bacteria, the douche and moisturizer induced an increase of IL-8, suggesting a potential to initiate inflammatory reaction. In the presence of L. crispatus, the proinflammatory effects of the douche and moisturizer were countered, and IL-8 production was inhibited in the presence of the other products. Conclusion: Some OTC vaginal products may be harmful to L. crispatus and alter the vaginal immune environment. Illustrated through these results, L. crispatus is essential in the preservation of the function of vaginal epithelial cells in the presence of some feminine hygiene products. More research should be invested

    Women are more susceptible to vaginal candidiasis when the host immune response is suppressed. The antioxidant nutrient beta-carotene is postulated to possess immunoenhancing properties. The purpose of this study was to investigate beta-carotene concentrations in exfoliated vaginal epithelial (EVE) cells in women with vaginal candidiasis. Beta-carotene levels in EVE cells, collected by a saline lavage technique from 22 women with vaginal candidiasis and 20 normal controls, were analyzed. The diagnosis of vaginal candidiasis was established by the presence of pruritus, white cheesy vaginal discharge, and a positive potassium hydroxide preparation. Beta-carotene levels were assayed using high pressure liquid chromatography. Vaginal cell concentrations of beta-carotene were significantly decreased in women with vaginal candidiasis (P < 0.001). Decreased beta-carotene levels, and possibly other antioxidants, may alter the local immune response resulting in disturbances in the vaginal flora, overgrowth of candida, and the development of vaginal candidiasis.

    Aerobic vaginitis (AV) is the name given in 2002 to a vaginal infectious entity which was not recognized as such before. It is characterized by abnormal (dysbiotic) vaginal microflora containing aerobic, enteric bacteria, variable levels of vaginal inflammation and deficient epithelial maturation. Although AV and bacterial vaginosis (BV) share some characteristics, such as a diminished number or absence of lactobacilli, increased discharge (fishy smelling in BV, while in severe forms of AV, a foul, rather rotten smell may be present) and increased pH (often more pronounced in AV), there are also striking differences between the two. There is no inflammation in women with BV, whereas the vagina of women with AV often appears red and edematous, and may even display small erosions or ulcerations. The color of the discharge in BV is usually whitish or gray and of a watery consistency, whereas in AV it is yellow to green and rather thick and mucoid. Women with BV do not have dyspareunia, while some women with severe AV do. Finally, the microscopic appearance differs in various aspects, such as the presence of leucocytes and parabasal or immature epithelial cells in AV and the absence of the granular aspect of the microflora, typical of BV. Despite all these differences, the distinction between AV and BV was not recognized in many former studies, leading to incomplete and imprecise diagnostic workouts and erroneous management of patients in both clinical and research settings. The prevalence of AV ranges between 7 and 12%, and is therefore less prevalent than BV. Although still largely undiagnosed, many researchers and clinicians increasingly take it into account as a cause of symptomatic vaginitis. AV can co-occur with other entities, such as BV and candidiasis. It can be associated with dyspareunia, sexually transmitted infections (such as human papilloma virus, human immunodeficiency virus, Trichomonas vaginalis and Chlamydia trachomatis), chorioamnionitis, fetal

    Full Text Available Abstract Backround Vaginitis is among the most common conditions women are seeking medical care for. Although these infections can easily be treated, the relapse rate is high. This may be due to inadequate use of the diagnostic potential. Methods We evaluated the misjudgement rate of the aetiology of vaginal complaints. A total of 220 vaginal samples from women with a vaginal complaint were obtained and analysed for numbers of total lactobacilli, H2O2-producing lactobacilli, total aerobic cell counts and total anaerobic cell counts including bifidobacteria, Bacteroides spp., Prevotella spp. Additionally, the presence of Atopobium vaginae, Gardnerella vaginalis, Candida spp. and Trichomonas vaginalis was evaluated by DNA-hybridisation using the PCR and Affirm VPIII Microbial Identification Test, respectively. Results The participating physicians diagnosed Bacterial vaginosis (BV as origin of discomfort in 80 cases, candidiasis in 109 cases and mixed infections in 8 cases. However, a present BV, defined as lack of H2O2-lactobacilli, presence of marker organisms, such as G. vaginalis, Bacteroides spp. or Atopobium vaginae, and an elevated pH were identified in only 45 cases of the women examined. Candida spp. were detected in 46 cases. Interestingly, an elevated pH corresponded solely to the presence of Atopobium vaginae, which was detected in 11 cases. Conclusion Errors in the diagnosis of BV and candida vulvovaginitis (CV were high. Interestingly, the cases of misjudgement of CV (77% were more numerous than that of BV (61%. The use of Amsel criteria or microscopy did not reduce the number of misinterpretations. The study reveals that the misdiagnosis of vaginal complaints is rather high.

    Vaginal bleeding and/or discharge in young girls may result from infection, urological problems, endocrine causes, bleeding disorders, dermatological conditions, trauma, sexual abuse, masses or foreign bodies. We report a case of excessive vaginal bleeding caused by a foreign body in a prepubertal girl with emphasis on the diagnostic challenges and pitfalls regarding imaging techniques. In our patient, although invasive and expensive investigations had been initially made, the foreign body was last detected only when a plain pelvic radiography was performed.

    by gynecologic examination were also recorded. Results: yeast belonging to the genus Candida was isolated from 18 (25% patients. The most prevalent species was C. albicans (77,8% and therefore, 22.2% were non-albicans species. The most prevalent among the non-albicans species was C. glabrata (16.7% followed by C. parapsilosis (5.6%. The symptoms most directly associated with Candida were itching and burning. Different from the symptoms directly associated with C. albicans infection, we observed that C. glabrata does not cause vaginal discharge. There was no positive association between predisponent factors such as age, education and contraceptive method used and the presence or absence of Candida. Conclusions: our results suggest: (i that there is a high prevalence of Candida species among women; (ii that non-albicans species play an important role in the vaginal medium; (iii that itching and burning are the most common symptoms in women with Candida, and (iv C. glabrata usually does not cause vaginal discharge. Finally, it is important to emphasize that our results are consistent with the present worldwide findings.

    Full Text Available We present a rare case of vaginal leiomyoma presenting as prolapsed vaginal mass in a 45 years old woman. The leiomyoma was found to arise from the right lateral vaginal fornix with a vascular stalk. MRI showed homogenous hypointense signals on T1W1 and iso to hyperintense signals on T2W1 images with moderate heterogenous enhancement on post contrast images. It was enucleated via vaginal route and the histopathological examination confirmed the diagnosis of vaginal leiomyoma.

    Streptococcus pyogenes or group A streptococcus (GAS) is a common cause of vulvo-vaginitis in pre-pubertal females but is uncommonly isolated from the vaginal swabs of adult females. We aimed to describe the clinical and laboratory findings of adult females with GAS isolated from vaginal swabs in a community and hospital laboratory. Over a 19 week period the two laboratories identified females ≥ 15 years of age with GAS isolated from vaginal swabs. At least 2 weeks after reporting, the referring doctor or midwife was telephoned by the authors for clinical information or the clinical notes were reviewed. Laboratory data were also collected. One hundred adult females with GAS isolated from vaginal swabs were identified from approximately 4500-5000 community laboratory, and 20 from approximately 2000 hospital laboratory swabs. Community patients were more likely to have presented with vaginal symptoms such as discharge, while hospital patients were more likely to have ascending infection related to pregnancy/recent delivery. Of the community patients, 15% were asymptomatic compared with 5% of the hospital patients. Review of Gram stain and culture quantification was not found to be particularly useful for discriminating between clinical infection and asymptomatic colonisation. Isolation of GAS from the vaginal swabs of adult females is uncommon. In the community setting it may represent infection with vulvo-vaginitis or asymptomatic colonisation. In the hospital setting, its isolation is frequently associated with pregnancy-related infectious complications.

    Full Text Available Background. Vaginal practices (VPs may increase HIV risk by injuring vaginal epithelium or by increasing risk of bacterial vaginosis, an established risk factor for HIV. Methods. HIV-negative Zimbabwean women (n=2,185 participating in a prospective study on hormonal contraception and HIV risk completed an ancillary questionnaire capturing detailed VP data at quarterly followup visits for two years. Results. Most participants (84% reported ever cleansing inside the vagina, and at 40% of visits women reported drying the vagina using cloth or paper. Vaginal tightening using cloth/cotton wool, lemon juice, traditional herbs/powders, or other products was reported at 4% of visits. Women with ≥15 unprotected sex acts monthly had higher odds of cleansing (adjusted odds ratio (aOR: 1.17, 95% CI: 1.04–1.32. Women with sexually transmitted infections had higher odds of tightening (aOR: 1.42, 95% CI: 1.08–1.86. Conclusion. Because certain vaginal practices were associated with other HIV risk factors, synergism between VPs and other risk factors should be explored.

VP was measured before, 1-5 days and 4-6 weeks after vaginal repair. Mean VP was four to five times higher during coughing and Valsalva compared to PFC...... and lifting 2 and 5 kg. Lifting in the walking position created a slightly higher VP compared to other lifting techniques, which did not differ. The VP did not increase when lifting 5 kg compared to 2 kg. Mean VP during coughing and Valsalva were significantly lower 1-5 days after the operation. VP...... was not related to the type of vaginal repair. The results imply that post-operative counselling should concentrate more on treating chronic cough and constipation than restrictions of moderate physical activities....

    No consensus exists about whether contraceptives cause an increased risk of vaginitis, including vulvovaginal candidosis (VVC). We investigated 495 women (252 who used contraceptives; 243 who did not) for the presence of VVC. Antifungal susceptibility testing was performed for five antifungal agents and for boric acid, and three virulence factors were also examined. We recovered 129 (26.1%) monofungal populations from vaginal samples of women with acute VVC (AVVC, n = 18), symptomatic recurrent VVC (RVVC, n = 22) and asymptomatic RVVC (n = 28), as well as of other contraceptive users who carried Candida in their vaginas (n = 61). It is important to note that the women who had VVC used the same contraceptive methods (p > 0.05). Candida albicans was the most common species isolated (45%), followed by C. glabrata (40.3%). Most of the vaginal yeast isolates exhibited low minimum inhibitory concentration levels for the five antifungals tested. However, this was not the case for boric acid. In addition, the yeast fungi that was derived from the AVVC and RVVC patients showed higher amounts of haemolytic activity than the yeast fungi found among the controls (p contraception does not predispose women to VVC (p > 0.05). Also, both host- and organism-related factors were required to achieve optimal clinical treatment for VVC.

    Fruit decay caused by pathogenic moulds is a major concern in the postharvest quality and shelf life of fruit. Blue mould decay is caused by Penicillium expansum (P. expansum) and is one of the most important postharvest diseases in cherries (Prunus avium L.). Synthetic fungicides are the main medium used to control pathogenic moulds. However, alternative approaches are available for developing safer technologies to control postharvest disease. An integrated approach that combines biological control, using antagonistic yeasts and modified atmosphere packaging (MAP) with cold storage is a promising alternative to synthetic fungicide treatment. In this work, two microperforated films (M10 and M50) and two antagonistic yeast strains (Hanseniaspora opuntiae L479 and Metschnikowia pulcherrima L672) were evaluated for their effectiveness to control the development of P. expansum in wounded cherries stored at 1°C. Results showed that the microperforated films had fungistatic effects, particularly M50, due to the level of CO2 achieved (mean CO2 of 11.2kPa at 35days), and the decrease in disease severity. Antagonistic yeasts, particularly Metschnikowia pulcherrima L672, delayed the development of P. expansum and decreased disease incidence and severity. The combination of MAP and antagonistic yeasts was the most effective approach to control P. expansum, during cold storage. Copyright © 2016 Elsevier B.V. All rights reserved.

  15. VAGINAL CANDIDIASIS – GYNECOLOGICAL ASPECT OF THE PROBLEM

    2014-12-01

    Full Text Available Vaginal candidiasis (VC is one of the most common reasons for consultations with a gynecologist, with an increasing trend in occurrence in female patients. It is estimated that 75% of all women experience an episode of vulvovaginal candidiasis in their lifetime, 50% of them experience at least a second episode, and 5% have recurrent candidiasis. Cervical and vaginal secretions act as the last line of defense from ascendant infection pathway spreading. Factors that may disturb vaginal ecosystem are: endogenous factors, way of life, infectious factors and iatrogenic factors. The most common cause of VC in 85-90% of cases is C. albicans, but other Candida species tend to be more likely to cause VVC (Candida tropicalis , Candida glabrata , C particulary, C crusei and so on. These non-albicans species have been found to be fluconazole and antimycotics resistant in more than 70% of cases. This is especially true for C. glabrata. There are several predisposing factors that have been associated with VC recurrence and resistance, such as Candida genotypes, resistance and virulence, immunodeficiency, unregulated hyperglycemia, use of oral contraceptives, long-term use of antibiotics. Therapy approach should be individual, including local and oral antimycotics until the symptoms disappear. The maintenance dose can be continuous or intermittent. Due to hormone concentration increase, increase in local glycogen, alternations of vaginal flora, VC incidence in pregnancy is two times higher in comparison to other female population. The problem of vaginal candidiasis requires individual approach, taking into account all the risk factors and accompanying physiological conditions or diseases in female patients.

    Full Text Available BACKGROUND: It is not known whether the addition of chemotherapy to radiation therapy improves outcomes in primary vaginal cancer. Here, we review clinical outcomes in patients with primary vaginal cancer treated with radiation therapy (RT or concurrent chemoradiation therapy (CRT. METHODS: Seventy-one patients with primary vaginal cancer treated with definitive RT with or without concurrent chemotherapy at a single institution were identified and their records reviewed. A total of 51 patients were treated with RT alone; 20 patients were treated with CRT. Recurrences were analyzed. Overall survival (OS and disease-free survival (DFS rates were estimated using the Kaplan-Meier method. Cox regression analysis was performed. RESULTS: The median age at diagnosis was 61 years (range, 18-92 years and the median follow-up time among survivors was 3.0 years. Kaplan-Meier estimates for OS and DFS differed significantly between the RT and CRT groups (3-yr OS = 56% vs. 79%, log-rank p = 0.037; 3-yr DFS = 43% vs. 73%, log-rank p = 0.011. Twenty-three patients (45% in the RT group had a relapse at any site compared to 3 (15% in the CRT group (p = 0.027. With regard to the sites of first relapse, 10 patients (14% had local only, 4 (6% had local and regional, 9 (13% had regional only, 1 (1% had regional and distant, and 2 (3% had distant only relapse. On univariate analysis, the use of concurrent chemotherapy, FIGO stage, tumor size, and date of diagnosis were significant predictors of DFS. On multivariate analysis, the use of concurrent chemotherapy remained a significant predictor of DFS (hazard ratio 0.31 (95% CI, 0.10-0.97; p = 0.04. CONCLUSIONS: Vaginal cancer results in poor outcomes. Adequate radiation dose is essential to ensure curative management. Concurrent chemotherapy should be considered for vaginal cancer patients.

    The objective of this study was to compare the postoperative infection rates between patients receiving either povidone-iodine (PI) or baby shampoo vaginal preparations before gynecologic surgery. Cohort study (Canadian Task Force classification II-2). University referral center for gynecologic endoscopy. All patients underwent minimally invasive gynecologic surgery including hysteroscopy or laparoscopy. The agents used for vaginal preparation were either baby shampoo in a 1:1 dilution with sterile normal saline solution or PI 7.5% scrub solution. Charts were reviewed for evidence of infection within 30 days of surgery (symptoms of urinary tract infection, abdominal or vaginal wound infections, temperature > 100.4 degrees F, and fungal or bacterial vaginitis). A total of 249 cases were collected; 96 subjects underwent surgery before the change to baby shampoo and 153 subjects after. Both groups were well matched for the types of surgery performed, age, risk factors for postoperative infections, and the postoperative diagnosis. The infection rates were 14/96 (14.6%) with PI preparation versus 18/153 (11.8%) with baby shampoo (p = .52). Baby shampoo should be studied as an alternative to PI because it is a nonirritating, inexpensive mild detergent. This preliminary study suggests that baby shampoo is as effective as PI in preventing postoperative infection.

    Lactobacilli are the dominant bacteria of the vaginal tract of healthy women, and imbalance of the local microbiota can predispose women to acquire infections, such as bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC). Although antimicrobial therapy is generally effective, there is still a high incidence of recurrence and increase of microbial resistance due to the repetitive use of antimicrobials. Thus, it has been suggested that administration of probiotics incorporating selected Lactobacillus strains may be an effective strategy for preventing vaginal infections. Accordingly, the in vitro probiotic potential of 23 lactobacilli isolated from the vaginal ecosystem of healthy women from Cuba was evaluated for use in BV and VVC treatments. Eight strains were selected based on their antagonist potential against Gardnerella vaginalis, Candida albicansor both. In vitro assays revealed that all these strains reduced the pathogen counts in co-incubation, showed excellent adhesive properties (biofilm formation and auto-aggregation), were able to co-aggregate with G. vaginalis and C. albicans, yielded high amounts of hydrogen peroxide and lactic acid and demonstrated high adhesion rates to epithelial HeLa cells. Interference tests within HeLa cells showed that all strains were able to reduce the adherence of pathogens by exclusion or displacement. Lactobacilli were able to inhibit HeLa cell apoptosis caused by pathogens when the cells were incubated with the probiotics prior to challenge. These results suggest that these strains have a promising probiotic potential and can be used for prevention or treatment of BV and VVC.

Trial of labour in an appropriate setting or delivery by pre-emptive Caesarean section for women with a singleton breech fetus at term. Reduced perinatal mortality, short-term neonatal morbidity, long-term infant morbidity, and short- and long-term maternal morbidity and mortality. Medline was searched for randomized trials, prospective cohort studies, and selected retrospective cohort studies comparing planned Caesarean section with a planned trial of labour; selected epidemiological studies comparing delivery by Caesarean section with vaginal breech delivery; and studies comparing long-term outcomes in breech infants born vaginally or by Caesarean section. Additional articles were identified through bibliography tracing up to June 1, 2008. The evidence collected was reviewed by the Maternal Fetal Medicine Committee of the Society of Obstetricians and Gynaecologists of Canada (SOGC) and quantified using the criteria and classifications of the Canadian Task Force on Preventive Health Care. This guideline was compared with the 2006 American College of Obstetrician's Committee Opinion on the mode of term singleton breech delivery and with the 2006 Royal College of Obstetrician and Gynaecologists Green Top Guideline: The Management of Breech Presentation. The document was reviewed by Canadian and International clinicians with particular expertise in breech vaginal delivery. The Society of Obstetricians and Gynaecologists of Canada. SUMMARY STATEMENTS: 1. Vaginal breech birth can be associated with a higher risk of perinatal mortality and short-term neonatal morbidity than

    Full Text Available We present the case of a 13-year-old girl with a recurrent urinary tract infection, malodorous vaginal discharge, and urinary incontinence caused by a retained vaginal foreign body. The foreign body, an aerosol cap retained for over 2 years, resulted in the formation of a ureterovaginal fistula, an extremely rare complication. The critical value of ultrasound and magnetic resonance urography in delineating the foreign body, the fistulous tract, and the intraperitoneal urine leak is described. Through this unique diagnostic dilemma, we wish to highlight that the evaluation of persistent unusual urinary symptoms and vaginal discharge in a young girl must include a thorough pelvic examination and focused imaging to look for retained vaginal foreign bodies.

    In spite of a few shortcomings such as over diagnosis and over treatment, syndromic management is a recommended practice in India for sexually transmitted infections (STIs). This study tries to find out the efficacy of syndromic management measured as symptomatic improvement in females with vaginal discharge syndrome. The objective of the study is to find out the effectiveness of syndromic management in terms of symptomatic improvement among females with vaginal discharge syndrome. A longitudinal study was conducted in Gynecology Department of Tertiary Care Hospital including 180 symptomatic females having vaginal discharge syndrome. Demographic profile, presenting complaints, menstrual history, obstetric history, partner history, and contraceptive history were noted. This was followed by clinical examination and specimen collection for laboratory tests and blood tests to find out type of STI including viral STI such as human immunodeficiency virus (HIV), herpes simplex virus (HSV), and hepatitis B surface antigen (HBsAg). Treatment was given according to syndromic management on the same day. All the participants were asked to come for follow-up after 15 days and their improvement in symptoms was noted as complete improvement, some improvement or no improvement on a five point scale. 63.9% cases showed complete improvement, while 36.1% showed some improvement. None of the patients was without any improvement. Vaginal discharge syndrome was most common between 20 and 30 years (43.4%), and 67.8% of symptomatic females with vaginal discharge syndrome belonged to the lower socioeconomic group. HSV infection was the most common (15%) associated viral infection with vaginal discharge syndrome, while hepatitis B infection was the least common (0.5%). HIV was reactive in 2.8% cases only. Syndromic management was found to be effective in relieving symptoms in most of the cases of vaginal discharge syndrome.

    Different types of vaginal fistulas is a relatively uncommon condition in the Western world but very frequent in developing countries. In the past, conventional vaginography was the radiological examination of choice for exploring this condition. CT and MRI are now both used for this purpose. Our objective was to test the feasibility and to explore the potential role of a new CT imaging technique implementing vaginal introitus obstruction and opacification of the vagina with iodine contrast agent, to show patency of a fistula. We describe the technical protocol of CT-vaginography as performed in Geneva University Hospitals, including vaginal catheterization with a Foley catheter and obstruction of the introitus by inflating the balloon of the catheter. We also report three cases of patients with suspected vaginal fistula who underwent CT-vaginography. The examinations were technically successful. In one patient, it revealed the presence of fistulous pathways from the vaginal fornix along the bilateral infected surgical prostheses. In a second patient, it showed a fistula between the vagina and the necrotic cavity of a recurrent cervical cancer. In a third patient, it proved the absence of a suspected vaginal fistula. CT-vaginography is a technically feasible CT protocol that provides anatomical and functional information on clinically suspected vaginal fistulas. Advances in knowledge: After the abandon of conventional vaginography in the era of transaxial imaging, the current modalities of imaging vaginal fistulas provide excellent anatomical detail but less functional information concerning the permeability of a vaginal fistulous pathway. We propose the use of CT-vaginography, a technical protocol that we describe in detail.

    genéticos podem explicar variações na composições da flora. Ressalta-se a necessidade de que tais conhecimentos sejam incorporados à pratica clínica do ginecologista e obstetra para o aprimoramento do cuidado às pacientes.The aim of this review is to update knowledge about the vaginal ecosystem, non-cultivation methods for bacterial identification (gene amplification, the Lactobacillus species that comprise normal vaginal flora and influence of host genetics on bacterial interactions with local innate and acquired immune defenses. A Medline (Pubmed search from 1997-2009 for relevant articles was performed and the most informative articles were selected. Non-culture techniques (gene amplification allow a comprehensive analysis of the vaginal ecosystem's composition. In the majority of women in the reproductive age there is a predominance of one or more species of Lactobacillus: L. crispatus, L. inners and L gasseri. However, in other apparently healthy women there is a deficiency or complete absence of Lactobacilli. Instead, there is a substitution by other lactic acid-producing bacteria: Atobium, Megasphaera and/or Leptotrichia species. The infectivity and/or proliferation of pathogenic bacteria in the vagina is suppressed by lactic acid production, by products of endogenous bacteria and by activation of local innate and acquired immunity. Vaginal epithelial cells produce several compounds with anti-microbial activity. These cells have Toll-like receptors on their membrane that recognize molecular patterns associated with pathogens. Recognition leads to production of pro-inflammatory cytokines and stimulation of antigen-specific immunity. The production of IgG and IgA antibodies is also triggered in the endocervix and vagina in response to infection. Vaginal flora composition and the immune mechanisms constitute important defenses. Criteria of normal and abnormal flora have to be reviewed and genetic polymorphism can explain variations in flora composition

    Full Text Available Background: The composition of the vaginal microbiota is known to be important for health. When infections occur, antimicrobial therapy is often poorly efficacious. Objective and design: We used 16S rRNA gene sequencing to characterize changes in the bacterial microbiota following oral antimicrobial and probiotic interventions. Results: While the bacterial vaginal profiles of women with vulvovaginal candidiasis were dominated by lactobacilli as in healthy women, and unchanged by therapy, Gardnerella vaginalis, Prevotella, Atopobium, Sneathia, and Megasphaera dominated the vagina of women with bacterial vaginosis (BV, and treatment with tinidazole plus Lactobacillus reuteri RC-14+L. rhamnosus GR-1 resulted in an increased relative abundance of indigenous L. iners or L. crispatus. Conclusions: The ability to restore homeostasis provides a rationale for conjoint use of probiotics with antibiotic treatment of BV.

    No well-defined Blastomyces-specific antigens are currently available. We used sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting to identify immunologically active molecules in the cell wall of B. dermatitidis. A major immunoreactive 120-kD protein (WI-1) was present in all five strains studied and comprised 5% of the protein in the cell wall extract obtained after freezing and thawing yeast cells. WI-1 was recognized by serum from all 10 patients with blastomycosis but by none of those from 5 patients with histoplasmosis. It was purified by electroelution, radiolabeled with 125I, and incorporated into a radioimmunoassay (RIA) for serodiagnosis of blastomycosis. Antibody to WI-1 was detected in 58 (85%) of 68 patients with blastomycosis (geometric mean titer, 1:2,981), in two (3%) of 73 patients with histoplasmosis, coccidioidomycosis, sporotrichosis, or candidiasis (titers, 1:86 and 1:91) and in none of 44 healthy persons. WI-1 was shown to be a surface molecule abundant on B. dermatitidis yeasts that were indirectly stained with serum from a rabbit immunized with WI-1. Approximately 0.93 pg of WI-1 or 4.7 x 10(6) WI-1 molecules were found on the surface of an individual yeast using an antigen-inhibition RIA; none was found on Histoplasma capsulatum or Candida albicans yeasts. We conclude that WI-1 is a novel, immunologically active surface molecule on the invasive form of B. dermatitidis and that WI-1 can be used to reliably detect antibody and study the immunopathogenesis of blastomycosis.

    This study aimed to assess the prevalence of pathological vaginal discharge and to describe risk factors associated with pregnant women. All women living in the city of Rio Grande, Southern Brazil, who gave birth in 2010 were included in the study. A standardized questionnaire was administered to collect information on demographic, reproductive, and health-related factors and morbidity during pregnancy. The chi-square test was used to compare proportions, and multivariate Poisson regression with robust variance was performed. Of the 2,395 women studied, 43% had pathological vaginal discharge during pregnancy. The adjusted analysis showed that younger women of lower socioeconomic condition, those with a past history of abortion, vaginal discharge in a previous pregnancy, and treated for depression, anemia, and urinary tract infection during their current pregnancy, were more likely to have pathological vaginal discharge. Vaginal discharge during pregnancy was highly prevalent in the sample studied calling for proper risk factor management at the primary care level.

    Full Text Available Vaginitis is one of the commonest reproductive tract infections in sexually active women. In the present study clinicoetiological characterization of infectious vaginitis amongst 380 women of reproductive age group (18–45 years was done. Bacterial vaginosis (BV was detected by Nugent’s scoring, Candida infection by culture, and trichomoniasis (TV by wet mount. One hundred and ten (28.9% women presented with symptoms of vaginitis. The presenting symptoms were vaginal discharge 106 (96.4%, vulval itching/irritation 19 (17.3%, malodor 5 (4.5%, pain in abdomen 3 (2.7%, and dysuria 1 (0.9%. The commonest etiology detected was Candida in 33 (30% cases, of which 18 (54.5% were C. albicans and 15 (45.5% non-albicans Candida (NAC infections. The NAC isolates were C. glabrata (n=10, C. tropicalis (n=3, and C. krusei (n=2. BV and TV were observed in 19 (17.3% and 2 (1.8% cases, respectively. A statistically significant association between Candida infection and presence of curdy-white discharge (p=0.001 and vulval itching/irritation (p=0.007 was noted. To conclude, we observed the etiological predominance of Candida infection, with considerable prevalence of NAC, indicating the need for microbiological investigation up to species level in cases of Candida infections, to ensure appropriate management.

    Research indicated that: (i) vaginal orgasm (induced by penile-vaginal intercourse [PVI] without concurrent clitoral masturbation) consistency (vaginal orgasm consistency [VOC]; percentage of PVI occasions resulting in vaginal orgasm) is associated with mental attention to vaginal sensations during PVI, preference for a longer penis, and indices of psychological and physiological functioning, and (ii) clitoral, distal vaginal, and deep vaginal/cervical stimulation project via different peripheral nerves to different brain regions. The aim of this study is to examine the association of VOC with: (i) sexual arousability perceived from deep vaginal stimulation (compared with middle and shallow vaginal stimulation and clitoral stimulation), and (ii) whether vaginal stimulation was present during the woman's first masturbation. A sample of 75 Czech women (aged 18-36), provided details of recent VOC, site of genital stimulation during first masturbation, and their recent sexual arousability from the four genital sites. The association of VOC with: (i) sexual arousability perceived from the four genital sites and (ii) involvement of vaginal stimulation in first-ever masturbation. VOC was associated with greater sexual arousability from deep vaginal stimulation but not with sexual arousability from other genital sites. VOC was also associated with women's first masturbation incorporating (or being exclusively) vaginal stimulation. The findings suggest (i) stimulating the vagina during early life masturbation might indicate individual readiness for developing greater vaginal responsiveness, leading to adult greater VOC, and (ii) current sensitivity of deep vaginal and cervical regions is associated with VOC, which might be due to some combination of different neurophysiological projections of the deep regions and their greater responsiveness to penile stimulation. © 2013 International Society for Sexual Medicine.

    Full Text Available Vulvovaginal candidiasis (VVC is one of the most prevalent vaginal infectious diseases, and there are controversial reports regarding the diversity of the associated vaginal microbiota. We determined the vaginal microbial community in patients with VVC, bacterial vaginosis (BV, and mixed infection of VVC and BV using Illumina sequencing of 16S rRNA tags. Our results revealed for the first time the highly variable patterns of the vaginal microbiome from VVC patients. In general, the alpha-diversity results of species richness and evenness showed the following order: normal control < VVC only < mixed BV and VVC infection < BV only. The beta-diversity comparison of community structures also showed an intermediate composition of VVC between the control and BV samples. A detailed comparison showed that, although the control and BV communities had typical patterns, the vaginal microbiota of VVC is complex. The mixed BV and VVC infection group showed a unique pattern, with a relatively higher abundance of Lactobacillus than the BV group and higher abundance of Prevotella, Gardnerella, and Atopobium than the normal control. In contrast, the VVC-only group could not be described by any single profile, ranging from a community structure similar to the normal control (predominated with Lactobacillus to BV-like community structures (abundant with Gardnerella and Atopobium. Treatment of VVC resulted in inconsistent changes of the vaginal microbiota, with four BV/VVC samples recovering to a higher Lactobacillus level, whereas many VVC-only patients did not. These results will be useful for future studies on the role of vaginal microbiota in VVC and related infectious diseases.

    The application of yeasts has great potential in reducing the economic damage caused by toxigenic fungi in the agriculture. Some yeasts may act as biocontrol agents inhibiting the growth of filamentous fungi. These species may also gain importance in the preservation of agricultural products and in the reduction of their mycotoxin contamination, yet the extent of mycotoxin production in the presence of biocontrol agents is relatively less understood. The application of yeasts in various technological processes may have a direct inhibitory effect on the toxin production of certain molds, which is independent of their growth suppressing effect. Furthermore, several yeast species are capable of accumulating mycotoxins from agricultural products, thereby effectively decontaminating them. Probiotic yeasts or products containing yeast cell wall are also applied to counteract mycotoxicosis in livestock. Several yeast strains are also able to degrade toxins to less-toxic or even non-toxic substances. This intensively researched field would greatly benefit from a deeper knowledge on the genetic and molecular basis of toxin degradation. Moreover, yeasts and their biotechnologically important enzymes may exhibit sensitivity to certain mycotoxins, thereby mounting a considerable problem for the biotechnological industry. It is noted that yeasts are generally regarded as safe; however, there are reports of toxin degrading species that may cause human fungal infections. The aspects of yeast-mycotoxin relations with a brief consideration of strain improvement strategies and genetic modification for improved detoxifying properties and/or mycotoxin resistance are reviewed here. © 2015 WILEY-VCH Verlag GmbH & Co.

    Abnormal vaginal discharge (AVD) caused by a variety of reproductive tract infections is a widespread syndrome among women in India and in other developing countries. The purpose of this study was to determine whether a polyherbal formulation, Praneem, can be used for the regression of the syndrome. A phase IotaIota randomized controlled study was carried out with Praneem polyherbal tablets and Betadine vaginal pessary in 99 women with AVD. The authors found that 92% of women using Praneem were relieved of their symptoms of AVD as against 81.6% women using Betadine. Significant reduction was also seen with both treatments in lower abdominal pain, vaginal itching, and dysuria. Thus, the study indicates the efficacy of Praneem for the treatment of AVD and provides a rationale for planning a further Phase III study on a larger sample size for definitive conclusions.

    Yeast is an excellent system for the expression of recombinant eukaryotic proteins. Both endogenous and heterologous proteins can be overexpressed in yeast (Phan et al., 2001; Ton and Rao, 2004). Because yeast is easy to manipulate genetically, a strain can be optimized for the expression of a specific protein. Many eukaryotic proteins contain posttranslational modifications that can be performed in yeast but not in bacterial expression systems. In comparison with mammalian cell culture expression systems, growing yeast is both faster and less expensive, and large-scale cultures can be performed using fermentation. While several different yeast expression systems exist, this chapter focuses on the budding yeast Saccharomyces cerevisiae and will briefly describe some options to consider when selecting vectors and tags to be used for protein expression. Throughout this chapter, the expression and purification of yeast eIF3 is shown as an example alongside a general scheme outline. © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Vaginitis is a rare disease in adult female dogs. However, knowledge regarding this illness is important because, if secondary to reproductive tract anomalies that go uncorrected, it can cause ascending uterine infections and, consequently, subfertility or even infertility. Usually, these infections are caused by Enterobacter or microorganisms from the urogenital inferior system, such as Staphylococcus spp, Streptococcus spp, Escherichia coli, Proteus spp, Pseudomonas aeruginosa, Pasteurella, etc. In some cases, vaginitis may be caused by primary infections with Brucella canis, which is zoonotic, or by canine herpesvirus; both of these agents have the potential to cause reproductive failure. The disease can occur in any age, breed or ovarian condition and can be identified by vaginal cytology, vaginoscopy and culture of vaginal secretions. The most common clinical signs are erythema of the vaginal mucous, vaginal discharge, pollakiuria, licking of the vulva and attraction of male dogs, independent of the phase of the estrous cycle. This disease is generally self-limiting, and the treatment, when necessary, consists of antibiotic therapy, vaginal cleaning with antiseptic and, eventually, surgical correction of predisposing abnormalities. A vaginite é uma afecção rara em cadelas adultas. É uma causa importante de subfertilidade ou infertilidade, quando secundária à anomalias do trato reprodutivo. Normalmente, são causadas por enterobactérias ou pela microbiota do sistema urogenital inferior, tais como Staphylococcus spp, Streptococcus spp, Escherichia coli, Proteus spp, Pseudomonas aeruginosa, Pasteurella, entre outras. Em alguns casos, pode ser primária como infecções por Brucella canis, a qual é uma zoonose ou herpesvírus canino, importante causa de falhas reprodutivas. A afecção acomete fêmeas de qualquer idade, raça ou condição ovariana. Os sinais clínicos envolvem mucosa vaginal hiperêmica, corrimento vulvar, polaqui

    Full Text Available The human vagina is inhabited by a range of microbes from a pool of over 50 species. Lactobacilli are the most common, particularly in healthy women. The microbiota can change composition rapidly, for reasons that are not fully clear. This can lead to infection or to a state in which organisms with pathogenic potential coexist with other commensals. The most common urogenital infection in premenopausal women is bacterial vaginosis (BV, a condition characterized by a depletion of lactobacilli population and the presence of Gram-negative anaerobes, or in some cases Gram-positive cocci, and aerobic pathogens. Treatment of BV traditionally involves the antibiotics metronidazole or clindamycin, however, the recurrence rate remains high, and this treatment is not designed to restore the lactobacilli. In vitro studies have shown that Lactobacillus strains can disrupt BV and yeast biofilms and inhibit the growth of urogenital pathogens. The use of probiotics to populate the vagina and prevent or treat infection has been considered for some time, but only quite recently have data emerged to show efficacy, including supplementation of antimicrobial treatment to improve cure rates and prevent recurrences.

    Disseminated emmonsiosis is an important AIDS-related mycosis in South Africa that is caused by Emergomycesafricanus, a newly described and renamed dimorphic fungal pathogen. In vitro antifungal susceptibility data can guide management. Identification of invasive clinical isolates was confirmed phenotypically and by sequencing of the internal transcribed spacer region. Yeast and mold phase MICs of fluconazole, voriconazole, itraconazole, posaconazole, caspofungin, anidulafungin, micafungin, and flucytosine were determined with custom-made frozen broth microdilution (BMD) panels in accordance with Clinical and Laboratory Standards Institute recommendations. MICs of amphotericin B, itraconazole, posaconazole, and voriconazole were determined by Etest. Fifty unique E. africanus isolates were tested. The yeast and mold phase geometric mean (GM) BMD and Etest MICs of itraconazole were 0.01 mg/liter. The voriconazole and posaconazole GM BMD MICs were 0.01 mg/liter for both phases, while the GM Etest MICs were 0.001 and 0.002 mg/liter, respectively. The fluconazole GM BMD MICs were 0.18 mg/liter for both phases. The GM Etest MICs of amphotericin B, for the yeast and mold phases were 0.03 and 0.01 mg/liter. The echinocandins and flucytosine had very limited in vitro activity. Treatment and outcome data were available for 37 patients; in a multivariable model including MIC data, only isolation from blood (odds ratio [OR], 8.6; 95% confidence interval [CI], 1.3 to 54.4; P = 0.02) or bone marrow (OR, 12.1; 95% CI, 1.2 to 120.2; P = 0.03) (versus skin biopsy) was associated with death. In vitro susceptibility data support the management of disseminated emmonsiosis with amphotericin B, followed by itraconazole, voriconazole, or posaconazole. Fluconazole was a relatively less potent agent. Copyright © 2017 American Society for Microbiology.

    Abnormal vaginal discharge is a common clinical problem in reproductive age group. It is the second most common problem after abnormal uterine bleeding. It is a neglected health problem, most commonly caused due to vulvovaginal candidiasis, trichomoniasis, and bacterial vaginosis (BV). The present study was conducted to determine the prevalence of common organisms causing vaginal discharge and also to know the variety of clinical presentation. A cross-sectional descriptive study was conducted in the Skin and STD Outpatient Department of Vinayaka Mission Kirupananda Variyar Medical College Hospital, Salem, who presented with abnormal vaginal discharge between September 2012 and September 2014. A total of 100 women in the reproductive age group who had symptoms of vaginitis were examined. Data were coded and analyzed. Out of the 100 patients examined, 77 (77%) cases were organism positive. Among the positive cases, BV (27%) was the most common microbiological cause of abnormal vaginal discharge, followed by trichomoniasis (25%), vaginal candidiasis (22%), combined infection (Candida and BV) (3%), and nonspecific cases (23%). Out of 100 cases, few cases showed discordance between clinical and laboratory diagnosis. This discordance can be due to pitfalls in identifying the causative agent clinically or obscuring of the findings due to improper treatment received for other ailments. Thus, clinico-investigative correlation is more important than other clinical findings alone.

    Full Text Available In prepuberal girls vulvo-vaginitis are caused by germs of intestinal origin,mycetes, Gardnerella vaginalis, protozoa. Shigella is an uncommon agent able to induce valvovaginitis in children. We report the case of a 7-year-old girl with chronic vulvo-vaginitis caused by S. flexneri. Antibiotic Susceptibility Testing revealed that S. flexnery was sensible to cefotaxime, amoxicillin, imipenem, ciprofloxacin, but resistant to amikacin, cefazolin, gentamycin, ampicillin and tetracycline. A treatment with ciprofloxacin brought to a rapid resolution of all symptoms. At the follows up at 3 and 6 months the patient did not report symptoms of infection or articular cartilage abnormality; microbiological evaluations were also negative. Even if it is a single case report and other clinical trial may be performed in order to validate this hypothesis,we speculate that in patient with vulvo-vaginal infection living in environment with low hygiene care, a carefully microbiological evaluation of uncommon agents may be performed.

    Full Text Available Women living with HIV and co-infected with bacterial vaginosis (BV are at higher risk for transmitting HIV to a partner or newborn. It is poorly understood which bacterial communities constitute BV or the normal vaginal microbiota among this population and how the microbiota associated with BV responds to antibiotic treatment.The vaginal microbiota of 132 HIV positive Tanzanian women, including 39 who received metronidazole treatment for BV, were profiled using Illumina to sequence the V6 region of the 16S rRNA gene. Of note, Gardnerella vaginalis and Lactobacillus iners were detected in each sample constituting core members of the vaginal microbiota. Eight major clusters were detected with relatively uniform microbiota compositions. Two clusters dominated by L. iners or L. crispatus were strongly associated with a normal microbiota. The L. crispatus dominated microbiota were associated with low pH, but when L. crispatus was not present, a large fraction of L. iners was required to predict a low pH. Four clusters were strongly associated with BV, and were dominated by Prevotella bivia, Lachnospiraceae, or a mixture of different species. Metronidazole treatment reduced the microbial diversity and perturbed the BV-associated microbiota, but rarely resulted in the establishment of a lactobacilli-dominated microbiota.Illumina based microbial profiling enabled high though-put analyses of microbial samples at a high phylogenetic resolution. The vaginal microbiota among women living with HIV in Sub-Saharan Africa constitutes several profiles associated with a normal microbiota or BV. Recurrence of BV frequently constitutes a different BV-associated profile than before antibiotic treatment.

    Symptomatic vaginal discharge is the most frequent symptom in women of reproductive age group. Owing to social stigma majority of affected women hesitate to seek medical consultation. Therefore the actual incidence of vaginal discharge is much more than what is reported. The aim of the study is to determine the microbiological profile of symptomatic vaginal discharge in rural area and its utility in the management of genital tract infection. This was a descriptive type of observational study, conducted in sexually active women of reproductive age group (18-45 years) attending the OPD/IPD of Obstetrics and Gynaecology Department of National Institute of Medical Sciences, Shobhanagar, Jaipur (Rajasthan), over a period of 18 months from June 2012 to December 2013. Hundred sexually active non pregnant women of reproductive age group (18-45 years) were included in the study. After taking consent general physical examination along with pelvic examination was performed. Two high vaginal swabs and blood sample were collected for various tests. Hanging drop preparation was immediately made. This was followed by gram staining and culture. Chlamydia trachomatis IgM antibody was detected by ELISA method. Out of 100 women with symptomatic vaginal discharge, specific diagnosis was obtained in 89% of cases whereas no specific aetiology was found in 11% cases. Mean age was 32.60 years. Fifty-three percent patient had Bacterial vaginosis, candidiasis was found in 14% cases, 16% had Chlamydia trachomatis infection while Trichomonas vaginalis infection was detected in 6% cases. Homogenous discharge was most prevalent (52%), followed by mucopurulant discharge in 23% of women. Patient with symptomatic vaginal discharge need to be actively managed with appropriate antimicrobial agents. Judicious management may be helpful in prevention of HIV, HPV, CIN and post infection sequelae.

    To investigate the correlated pathogenetic factors and vaginal local immunity in vulvovaginal candidiasis (VVC). A case control study was conducted to compare VVC group (60 cases) with normal group (60 cases). All of the women filled up the specific questionnaires. Routine examination, pH test and bacterial culture were done on the vaginal discharge. Cytokines of the vaginal lavage were measured by enzyme linked immunosorbent assay. (1) Outcomes of the questionnaires: there was no significant difference between the two groups in educational background, knowledge of gynecologic infection, history of gynecologic infection, hygienic habit, sex life, or use of medicine (P > 0.05). The incidence of chronic cervicitis in normal group (43%, 26/60) was higher than in VVC group (22%, 13/60; P vaginal pH between the two groups (P > 0.05). (3) Detection rate of candida albicans by vaginal discharge routine examination was 72% (43/60). (4) The concentrations of interleukin (IL) 2, and IL-4 in vaginal lavage did not show significant difference between the two groups (P > 0.05), but the concentrations of human defensin 5, human beta-defensin (HBD) 1, and HBD2 in VVC group [(0.94 +/- 0.44) mg/L, (3.1 +/- 0.4) microg/L, (10 +/- 6) microg/L] were higher than normal group (P infection, history of gynecologic infection, hygienic habit, sex life, or use of medicine in the child-bearing period. Human defensin may be closely correlated with the pathogenesis of VVC.

    Infectious morbidity affecting the postoperative course has long been a concern for obstetricians and gynecologists. The incidence of postoperative infections approaches 38%. The third most common nosocomial infection is surgical site infection. The realm of postoperative infections includes obstetric and gynecologic sources. An understanding of the basic fundamentals of the vaginal flora and addressing host and surgical risk factors can aid in prevention of postoperative infections, which result in significant morbidity and mortality.

    1998-01-01

    This investigation evaluated immunity to vaginal herpes simplex virus type 2 (HSV-2) infection after local or parenteral immunization with attenuated HSV-2. Vaginal immunization induced sterilizing immunity against challenge with a high dose of wild-type virus, whereas parenteral immunizations protected against neurologic disease but did not entirely prevent infection of the vagina. Vaginal immunization caused 86- and 31-fold increases in the numbers of immunoglobulin G (IgG) plasma cells in the vagina at 6 weeks and 10 months after immunization, whereas parenteral immunizations did not increase plasma cell numbers in the vagina. Vaginal secretion/serum titer ratios and specific antibody activities in vaginal secretions and serum indicated that IgG viral antibody was produced in the vagina and released into vaginal secretions at 6 weeks and 10 months after vaginal immunization but not after parenteral immunizations. In contrast to the case for plasma cells, the numbers of T and B lymphocytes in the vagina were similar in vaginally and parenterally immunized mice. Also, lymphocyte numbers in the vagina were markedly but similarly increased by vaginal challenge with HSV-2 in both vaginally and parenterally immunized mice. Lymphocyte recruitment to the vagina after virus challenge appeared to involve memory lymphocytes, because it was not observed in nonimmunized mice. Thus, local vaginal immunization with attenuated HSV-2 increased the number of IgG plasma cells in the vagina and increased vaginal secretion/serum titer ratios to 3.0- to 4.7-fold higher than in parenterally immunized groups but caused little if any selective homing of T and B lymphocytes to the vagina.

    We aimed to investigate the detection of nanobacteria (NB) from expressed prostatic secretions (EPS) in patients with category III chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and from vaginal swabs in patients with vaginitis by reverse transcriptase polymerase chain reaction (RT-PCR) and to evaluate the association between NB and Neisseria gonorrhea, Chlamydia trachomatis, Ureaplasma urealyticum (U. urealyticum), Mycoplasma hominis, Trichomonas vaginalis, and Mycoplasma genitalium. A group of 11 men attending a specialized CP/CPPS clinic and a group of 157 women who reported symptoms of lower genital tract infection were enrolled in this study. NB were detected by RT-PCR. A Seeplex Sexually Transmitted Disease Detection assay (Seegene Inc., Seoul, Korea) was used that could detect DNA for 6 types of sexually transmitted pathogens. In EPS samples, the detection rate of NB in patients with CP/CPPS was 9.1%, and 9 (5.7%) of 157 vaginitis patients showed positive results in RT-PCR for NB in vaginal swabs. Associations observed among the 7 microorganisms included 6 (54.5%) patients who tested positive on EPS and 75 (47.8%) patients who tested positive on vaginal swabs. Five patients with vaginitis were found to have monoinfection of NB (6.7%). We found that conventional RT-PCR for NB was rapid, simple, low in cost, and easily available for the detection of NB, and that NB may be a possible etiological factor for vaginitis and CP/CPPS. The prevalence of U. urealyticum among the four patients with NB coinfection was 75%; the presence of U. urealyticum might therefore raise suspicion for nanobacterial infection.

    Budding yeast (Saccharomyces cerevisiae) and fission yeast (Schizosaccharomyces pombe) are two popular model organisms for virus research. They are natural hosts for viruses as they carry their own indigenous viruses. Both yeasts have been used for studies of plant, animal and human viruses. Many positive sense (+) RNA viruses and some DNA viruses replicate with various levels in yeasts, thus allowing study of those viral activities during viral life cycle. Yeasts are single cell eukaryotic organisms. Hence, many of the fundamental cellular functions such as cell cycle regulation or programed cell death are highly conserved from yeasts to higher eukaryotes. Therefore, they are particularly suited to study the impact of those viral activities on related cellular activities during virus-host interactions. Yeasts present many unique advantages in virus research over high eukaryotes. Yeast cells are easy to maintain in the laboratory with relative short doubling time. They are non-biohazardous, genetically amendable with small genomes that permit genome-wide analysis of virologic and cellular functions. In this review, similarities and differences of these two yeasts are described. Studies of virologic activities such as viral translation, viral replication and genome-wide study of virus-cell interactions in yeasts are highlighted. Impacts of viral proteins on basic cellular functions such as cell cycle regulation and programed cell death are discussed. Potential applications of using yeasts as hosts to carry out functional analysis of small viral genome and to develop high throughput drug screening platform for the discovery of antiviral drugs are presented.

  13. Formulation of the microbicide INP0341 for in vivo protection against a vaginal challenge by Chlamydia trachomatis.

    Directory of Open Access Journals (Sweden)

    Christian Pedersen

    Full Text Available The salicylidene acylhydrazide (SA compounds have exhibited promising microbicidal properties. Previous reports have shown the SA compounds, using cell cultures, to exhibit activity against Chlamydia trachomatis, herpes simplex virus and HIV-1. In addition, using an animal model of a vaginal infection the SA compound INP0341, when dissolved in a liquid, was able to significantly protect mice from a vaginal infection with C. trachomatis. To expand upon this finding, in this report INP0341 was formulated as a vaginal gel, suitable for use in humans. Gelling agents (polymers with inherent antimicrobial properties were chosen to maximize the total antimicrobial effect of the gel. In vitro formulation work generated a gel with suitable rheology and sustained drug release. A formulation containing 1 mM INP0341, 1.6 wt% Cremophor ELP (solubility enhancer and 1.5 wt% poly(acrylic acid (gelling and antimicrobial agent, was chosen for studies of efficacy and toxicity using a mouse model of a vaginal infection. The gel formulation was able to attenuate a vaginal challenge with C. trachomatis, serovar D. Formulations with and without INP0341 afforded protection, but the inclusion of INP0341 increased the protection. Mouse vaginal tissue treated with the formulation showed no indication of gel toxicity. The lack of toxicity was confirmed by in vitro assays using EpiVaginal tissues, which showed that a 24 h exposure to the gel formulation did not decrease the cell viability or the barrier function of the tissue. Therefore, the gel formulation described here appears to be a promising vaginal microbicide to prevent a C. trachomatis infection with the potential to be expanded to other sexually transmitted diseases.

    To evaluate whether single-dose treatments are as effective as standard therapy in the syndromic management of vaginal discharge. A randomized controlled effectiveness trial compared single-dose tinidazole plus fluconazole (TF) with treatment for 7 days with metronidazole plus 3 days of treatment with vaginal clotrimazole (MC) among 1570 women presenting with vaginal discharge at primary health care institutions in Ghana, Guinea, Mali and Togo. Participants were randomly allocated to one of the two treatments by research nurses or physicians using precoded envelopes. Effectiveness was assessed by symptomatic response on day 14. CLINICAL IDENTIFIER ClinicalTrials.gov NCT00313131. The two treatment regimens had similar effectiveness: complete resolution was seen in 66% (TF) and 64% (MC) and partial resolution in 33% (TF) and 34% (MC) of participants (P = 0.26). Effectiveness was similar among subgroups with vulvovaginal candidiasis, Trichomonas vaginalis vaginitis or bacterial vaginosis. The two treatment regimens had a similar effectiveness among human immunodeficiency virus (HIV)-infected (TF: n = 76, 71% complete resolution, 28% partial; MC: n = 83, 72% complete resolution, 25% partial, P = 0.76) and HIV-uninfected women (TF: n = 517, 68% complete, 32% partial; MC: n = 466, 65% complete, 33% partial, P = 0.20). Cervical infections with Neisseria gonorrhoeae, Chlamydia trachomatis and Mycoplasma genitalium were uncommon among women not involved in sex work, were associated with bacterial vaginosis or T. vaginalis vaginitis, and did not alter response to treatment with agents active against vaginal infections. Four-fifths of women not relieved by a single dose of TF had a favourable response when MC was administered as second-line treatment. Single-dose TF is as effective as multiple-dose MC in the syndromic management of vaginal discharge, even among women with HIV-infection. Given its low price and easier adherence, TF should be considered as a first

    Full Text Available A total of 106 women with vaginitis in Nicaragua were studied. The positive rate for the identification of Candida species was 41% (44 positive cultures out of 106 women with vaginitis. The sensitivity of microscopic examination of wet mount with the potassium hydroxide (KOH was 61% and 70% with Gram's stain when using the culture of vaginal fluid as gold standard for diagnosis of candidiasis. Among the 44 positives cultures, isolated species of yeast from vaginal swabs were C. albicans (59%, C. tropicalis (23%, C. glabrata (14% and C. krusei (4%. This study reports the first characterization of 26 C. albicans stocks from Nicaragua by the random amplified polymorphic DNA method. The genetic analysis in this small C. albicans population showed the existence of linkage disequilibrium, which is consistent with the hypothesis that C. albicans undergoes a clonal propagation.

    This study aims to determine the prevalence self-reported abnormal vaginal discharge and to identify associated risk factors in pregnant women in the municipality of Rio Grande, Rio Grande do Sul State, Brazil. A standardized questionnaire was applied to all pregnant women admitted for delivery in local maternity hospitals. The chi-square test was used to compare proportions, and Poisson regression was applied using multivariate analysis. Prevalence of vaginal discharge was 40%. Adjusted analysis showed the following prevalence ratios for vaginal discharge: 1.6 (1.4-1.8) for adolescents; 1.3 (1.1-1.6) for 8 years of schooling or less; 1.3 (1.1-1.5) for alcohol consumption; 2.0 (1.8-2.2) for vaginal discharge in the previous pregnancy; 1.4 (1.3-1.6) for urinary tract infection in the current pregnancy; and 0.8 (0.7-0.9) for history of prematurity. Local health services should target adolescent women, those with low schooling or low family income, and those with a history of vaginal discharge in the previous pregnancy or urinary tract infection in the current pregnancy.

  4. Prevention of vaginal and rectal HIV transmission by antiretroviral combinations in humanized mice.

    Directory of Open Access Journals (Sweden)

    Philippe A Gallay

    Full Text Available With more than 7,000 new HIV infections daily worldwide, there is an urgent need for non-vaccine biomedical prevention (nBP strategies that are safe, effective, and acceptable. Clinical trials have demonstrated that pre-exposure prophylaxis (PrEP with antiretrovirals (ARVs can be effective at preventing HIV infection. In contrast, other trials using the same ARVs failed to show consistent efficacy. Topical (vaginal and rectal dosing is a promising regimen for HIV PrEP as it leads to low systematic drug exposure. A series of titration studies were carried out in bone marrow/liver/thymus (BLT mice aimed at determining the adequate drug concentrations applied vaginally or rectally that offer protection against rectal or vaginal HIV challenge. The dose-response relationship of these agents was measured and showed that topical tenofovir disoproxil fumarate (TDF and emtricitabine (FTC can offer 100% protection against rectal or vaginal HIV challenges. From the challenge data, EC50 values of 4.6 μM for TDF and 0.6 μM for FTC for HIV vaginal administration and 6.1 μM TDF and 0.18 μM for FTC for rectal administration were obtained. These findings suggest that the BLT mouse model is highly suitable for studying the dose-response relationship in single and combination ARV studies of vaginal or rectal HIV exposure. Application of this sensitive HIV infection model to more complex binary and ternary ARV combinations, particularly where agents have different mechanisms of action, should allow selection of optimal ARV combinations to be advanced into pre-clinical and clinical development as nBP products.

    This is a study for assessment of a quantitative approach in pregnant women (N=104), in which findings of vaginal infection were compared. The findings were obtained by two means, flowchart of vaginal discharge, and typical examinations in the clinical nursing practice. Data were collected from January to July 2011 through interviews and gynecological examinations. The flowchart showed no efficacy to identify candidiasis and trichomoniasis. Furthermore, it showed low sensitivity (0.0%; 50%) and positive predictive value (0.0%; 3.6%) for both infections, and low specificity for trichomoniasis (46%). The flowchart was shown to be satisfactory for bacterial vaginosis, with high sensitivity (100%), negative predictive value (100%), and accuracy (74%). We conclude that use of the flowchart should be reassessed, as it was not able to identify important infections in pregnant women. A continuous effort must be directed for development of effective tests in order to prevent the spread of infection and reduce the number of unnecessary treatments.

    Full Text Available Background: Vaginal lactobacilli offer protection against recurrent urinary infections, bacterial vaginosis, and vaginal candidiasis. Objective: To characterise the isolated vaginal lactobacilli strains for their probiotic properties and to compare their probiotic potential. Methods: The Lactobacillus strains were isolated from vaginal samples by conventional culturing and identified by sequencing of the 16S rDNA fragment. Several functional properties were detected (production of hydrogen peroxide and lactic acid; antagonistic activity against Escherichia coli, Candida albicans, Candida glabrata, and Gardnerella vaginalis; auto-aggregation and adhesiveness as well as safety (haemolytic activity, antibiotic susceptibility, presence of transferrable resistance genes. Results: A total of 135 vaginal lactobacilli strains of three species, Lactobacillus crispatus (56%, Lactobacillus jensenii (26%, and Lactobacillus gasseri (18% were characterised using several functional and safety tests. Most of L. crispatus (89% and L. jensenii (86% strains produced H2O2. The best lactic acid producers were L. gasseri (18.2±2.2 mg/ml compared to L. crispatus (15.6±2.8 mg/ml and L. jensenii (11.6±2.6 mg/ml (p<0.0001; p<0.0001, respectively. L. crispatus strains showed significantly higher anti-E. coli activity compared to L. jensenii. L. gasseri strains expressed significantly lower anticandidal activity compared to L. crispatus and L. jensenii (p<0.0001. There was no significant difference between the species in antagonistic activity against G. vaginalis. Nearly a third of the strains were able to auto-aggregate while all the tested strains showed a good ability to adhere to HeLa cells. None of the tested lactobacilli caused haemolysis. Although phenotypical resistance was not found to ampicillin, chloramphenicol, erythromycin, gentamycin, tetracycline, and vancomycin, the erm(B, tet(M, and tet(K were detected in some strains.

    Neonatal safety data along with national guidelines have prompted renewed interest in vaginal delivery of twins, particularly in the case of the noncephalic second twin. Yet, the rising rate of twin cesarean deliveries, coupled with the national decline in operative obstetrics, raises concerns about the availability of providers who are skilled in twin vaginal birth. Providers are key stakeholders for increasing rates of twin vaginal delivery. We surveyed a group of practicing obstetricians to explore potential barriers to the vaginal birth of twins with a focus on delivery of the noncephalic second twin. Among 107 responding providers, only 57% would deliver a noncephalic second twin by breech extraction. Providers who preferred breech extraction had a higher rate of maternal-fetal medicine subspecialty training (26.2% vs 4.3%; P30 sets of twins annually (57.4% vs 34.8%; P=.02). Most providers (54.2%) were familiar with the findings from the recent randomized trial that demonstrated the safety of twin vaginal birth. However, knowledge of the trial was not associated statistically with a preference for breech extraction (62.3% vs 43.5%; P=.05). Providers who preferred breech extraction were more likely to agree with recent society guidelines that encourage the vaginal birth of twins (86.9% vs 63.0%; Pinnovation. Without novel provider-focused strategies, we may relinquish passively the requisite skills for not only our patients but also for future generations of obstetricians. Copyright © 2017 Elsevier Inc.

    To establish the frequency of epidural analgesia for vaginal delivery. The research includes 51 632 deliveries for 16 years period. Total frequency of vaginal delivery with EA, compared to total number of vaginal deliveries for period is 11.77%. The frequency shows tendency to slowly increase in the beginning of the period, probably because of getting experienced among some of the obstetricians, after then frequency stay relatively constant. Except care of somatic health of mother and foetus, modern obstetrics requires to ensure maximum comfort of parturient, to satisfy requirements of modern women for "painless" delivery and leave a positive memory of birth. That is why more frequently use of EA for vaginal delivery is necessary. EA is an approved method for anesthetizing vaginal delivery. It is established slowly increasing frequency of EA for anesthetizing vaginal delivery. The frequency of EA in University hospital "Maichin dom" is relatively low in comparison with mentioned in literature values, which raises the question of finding ways to further promote and increase the application of EA.

    Follette, Peter J; Arkowitz, Robert A

    2009-01-01

    Virtually all eukaryotic cells can grow in a polarized fashion in response to external signals. Cells can respond to gradients of chemoattractants or chemorepellents by directional growth, a process referred to as chemotropism. The budding yeast Saccharomyces cerevisiae undergoes chemotropic growth during mating, in which two haploid cells of opposite mating type grow toward one another. We have shown that mating pheromone gradients are essential for efficient mating in yeast and have examined the chemotropism defects of different yeast mutants. Two methods of assessing the ability of yeast strains to respond to pheromone gradients are presented here.

    Vulvovaginal candidiasis (VVC) and recurrent VVC (RVVC) remain major health problems for women. VT-1161, a novel fungal CYP51 inhibitor which has potent antifungal activity against fluconazole-sensitive Candida albicans, retained its in vitro potency (MIC50 of ≤0.015 and MIC90 of 0.12 μg/ml) against 10 clinical isolates from VVC or RVVC patients resistant to fluconazole (MIC50 of 8 and MIC90 of 64 μg/ml). VT-1161 pharmacokinetics in mice displayed a high volume of distribution (1.4 liters/kg), high oral absorption (73%), and a long half-life (>48 h) and showed rapid penetration into vaginal tissue. In a murine model of vaginal candidiasis using fluconazole-sensitive yeast, oral doses as low as 4 mg/kg VT-1161 significantly reduced the fungal burden 1 and 4 days posttreatment (P fluconazole (MIC of 64 μg/ml) but fully sensitive in vitro to VT-1161 was used. When an isolate partially sensitive to VT-1161 (MIC of 0.12 μg/ml) and moderately resistant to fluconazole (MIC of 8 μg/ml) was used, VT-1161 remained efficacious, whereas fluconazole was efficacious on day 1 but did not sustain efficacy 4 days posttreatment. Both agents were inactive in treating an infection with an isolate that demonstrated weaker potency (MICs of 2 and 64 μg/ml for VT-1161 and fluconazole, respectively). Finally, the plasma concentrations of free VT-1161 were predictive of efficacy when in excess of the in vitro MIC values. These data support the clinical development of VT-1161 as a potentially more efficacious treatment for VVC and RVVC. Copyright © 2015, American Society for Microbiology. All Rights Reserved.

    Objectives Some vaginal bacterial communities are thought to prevent infection by sexually transmitted organisms. Prior work demonstrated that the vaginal microbiota of reproductive-age women cluster into five types of bacterial communities; 4 dominated by Lactobacillus species (L. iners, L. crispatus, L. gasseri, L. jensenii), and one (termed community state type (CST) IV) lacking significant numbers of lactobacilli and characterized by higher proportions of Atopobium, Prevotella, Parvimonas, Sneathia, Gardnerella, Mobiluncus, and other taxa. We sought to evaluate the relationship between vaginal bacterial composition and Trichomonas vaginalis. Methods Self-collected vaginal swabs were obtained cross-sectionally from 394 women equally representing four ethnic/racial groups. T. vaginalis screening was performed using PCR targeting the 18S rRNA and β-tubulin genes. Vaginal bacterial composition was characterized by pyrosequencing of barcoded 16S rRNA genes. A panel of eleven microsatellite markers was used to genotype T. vaginalis. The association between vaginal microbiota and T. vaginalis was evaluated by exact logistic regression. Results T. vaginalis was detected in 2.8% of participants (11/394). Of the eleven T. vaginalis-positive cases, eight (72%) were categorized as CST-IV, two (18%) as communities dominated by L. iners and one (9%) as L. crispatus-dominated (p-value:0.05). CST-IV microbiota were associated with an 8-fold increased odds of detecting T. vaginalis compared to women in the L. crispatus-dominated state (OR:8.26, 95% CI:1.07–372.65). Seven of the 11 T. vaginalis isolates were assigned to two genotypes. Conclusion T. vaginalis was associated with vaginal microbiota consisting of low proportions of lactobacilli and high proportions of Mycoplasma, Parvimonas, Sneathia, and other anaerobes.

    A healthy vaginal environment is predominated by certain Lactobacillus species, which lead to the prevention of infections of the reproductive tract. This study examined the characteristics of cultivable Lactobacillus species in both healthy women and women with bacterial vaginosis (BV). Between November 2011 and September 2013, 139 women attending a women's clinic in Mysore, India, were evaluated for BV in a cross-sectional study. BV was diagnosed using Amsel's criteria: homogeneous vaginal discharge, vaginal pH >4.5, production of amines, and presence of “clue” cells. Those with three or more of the characteristics were considered to have BV. Vaginal swabs were then cultured in Rogosa agar and de Man-Rogosa-Sharpe broth. Gram-positive lactobacilli generating 600–800 bp amplicons by16 sRNA were further characterized by sequencing. Cultivable vaginal samples were obtained from 132 women (94.9 %). According to the Amsel criteria, 83 women (62.1 %) were healthy, and 49 (37.1 %) had BV. Eleven different Lactobacillus species were isolated from 47 women. The common lactobacilli species found in this sample included L. crispatus (39.6 %), L. gasseri (45.8 %), and L. jensenii (14.6 %). Lactobacilli were isolated from 39 healthy women and eight with BV. L. gasseri was cultured from 18.8 % of healthy women and 6.1 % with BV. The presence of L. reuteri was significantly associated with normal vaginal microbiota (P-value = 0.026). These results further our understanding of vaginal lactobacilli colonization and richness in this particular population. Our findings showed that lactobacilli species present in the vaginas of healthy women in India do not differ from those reported from other countries. PMID:25873579

    Full Text Available Abstract Background The aim of this study was to investigate the presence of multidrug resistant yeasts in the faeces of synanthropic wild birds from the Bangsar suburb of Kuala Lumpur. Methods Species characterisations of yeast isolates and determinations of antimycotic susceptibility profiles were undertaken using the commercial characterization kit, Integral System Yeasts Plus (Liofilchem, Italy. Results Fourteen species of yeasts were detected in the bird faecal samples.Candida albicans was present in 28.89% of bird faecal samples, Candida krusei (13.33%, Candida tropicalis (4.44%, Candida glabrata (4.44%, Candida parapsilosis (2.22%, Candida lambica (2.22%, Candida stellatoidea (2.22%, Candida rugosa (2.22% and Candida lusitaniae (2.22%. Amongst the non-candidal yeast isolates, Cryptococcus laurentii was present in 6.67% of bird faecal samples, Cryptococcus uniguttulatus (4.44%, Saccharomyces cerevisiae (4.44%, Trichosporon pullulans (2.22%, Trichosporon pullulans/Cryptococcus albidus (8.89% and Rhodotorula rubra/Rhodotorula glutinis (4.44%. Of the isolated yeasts, 18.1% (or 26/144 were found to be resistant to all 11 antimycotic agents they were tested against i.e. Nystatin, Amphotericin B, Flucytosine, Econazole, Ketoconazole, Clotrimazole, Miconazole, Itraconazole, Voriconazole, Fluconazole 16 and Fluconazole 64. 45.8% (or 66/144 of the bird faecal yeast isolates were resistant to four or more of the 11 antimycotic agents they were tested against. Conclusions This finding is of public health significance as these synanthropic wild birds may be reservoirs for transmission of drug resistant yeast infections to humans.

    Background: Vaginal stones are rare and often unknown entities. Most urologists may never see a case in their careers. Case Presentation: We present the case of a 34-year-old bedridden Caucasian woman with mental and physical disabilities who presented with a large primary vaginal calculus, which, surprisingly, had remained undiagnosed until the patient suffered a right renal colic caused by a ureteral stone. The vagina was completely filled and a digital examination was not possible. For this reason, the stone was removed using surgical pliers with some maneuvering. A vesicovaginal fistula was excluded, as well as foreign bodies or other nidi of infection. After, urethral lithotripsy was performed as planned. The postoperative course and follow-up were uneventful. Conclusion: Although vaginal calculi are extremely rare in literature, their differential diagnosis should be considered in women with incontinence and associated disabilities, paraplegia, or prolonged immobilization in recumbent position.

    Evidence was recently provided for vaginal orgasm, orgasm triggered purely by penile-vaginal intercourse (PVI), being associated with better psychological functioning. Common sex education and sexual medicine approaches might undermine vaginal orgasm benefits. To examine the extent to which women's vaginal orgasm consistency is associated with (i) being told in childhood or adolescence that the vagina was the important zone for inducing female orgasm; (ii) how well they focus mentally on vaginal sensations during PVI; (iii) greater PVI duration; and (iv) preference for above-average penis length.   In a representative sample of the Czech population, 1,000 women reported their vaginal orgasm consistency (from never to almost every time; only 21.9% never had a vaginal orgasm), estimates of their typical foreplay and PVI durations, what they were told in childhood and adolescence was the important zone for inducing female orgasm, their degree of focus on vaginal sensations during PVI, and whether they were more likely to orgasm with a longer than average penis. The association of vaginal orgasm consistency with the predictors noted above. Vaginal orgasm consistency was associated with all hypothesized correlates. Multivariate analysis indicated the most important predictors were being educated that the vagina is important for female orgasm, being mentally focused on vaginal sensations during PVI, and in some analyses duration of PVI (but not foreplay) and preferring a longer than average penis. Focusing attention on penile-vaginal sensation supports vaginal orgasm and the myriad benefits thereof. Brody S, and Weiss P.

    To analyze the relationship between the level of knowledge about human papilloma virus and the acceptance of vaginal self-sampling as a cervical cancer diagnostic test among Mexican women who have already experienced vaginal self-sampling at home. A structured questionnaire consisting of 22 questions was applied to 690 women in the state of Morelos who had taken a vaginal self-sample at home. The aspects explored were the level of knowledge about transmission of the human papilloma virus, identification of the virus as a necessary cause of cervical cancer, and clinical manifestations of infection and treatment. A knowledge index was constructed, identifying the relationship between the index and the women's acceptance of self-sampling, and their degree of trust in the procedure. The statistical analysis included a logistic regression with estimates of measures of association and their respective 95% confidence intervals. The level of knowledge about human papillomavirus showed a positive association with the degree of acceptance of vaginal self-sampling (OR 2.9; 95% CI 1.0-5.01) and the women's level of confidence (OR 2.9; 95% CI 1.8-4.67). The level of knowledge increased with level of education and was higher in younger women. In order for women with an increased risk of cervical cancer to continue participating in vaginal self-sampling, they must be well informed about the virus. This is especially true for older women, those with lower levels of education, and those in lower socioeconomic levels.

    Warm-water cleaning toilets, or ‘bidet toilets’, are one of the most popular household goods in Japan. However, a recent large-scale survey raised questions about the relationship between bidet toilet use and bacterial vaginitis as reflecting bacterial vaginosis with inflammation. Recently, gynecologists have expressed concerns about the increase in aggravated vaginal microflora in habitual bidet users. Therefore, the present study was designed to clarify the possible relevancy of bidet usage to changes in vaginal microflora. Two hundred and sixty-eight non-pregnant women of reproductive age, with an increase in vaginal discharge, consented to enter the study. On outpatient visit, an aliquot of cervicovaginal secretion was obtained by a sterilized cotton swab and cultured using standard culture systems. Normal microflora (Lactobacillus species) was not present in 42.86% of bidet toilet users, compared to 8.77% of non-users. Fecal bacteria were detected in 50 of the 268 cases (18.66%), 46 cases in users (92%) and only 4 cases in non-users (8%). Contamination by other pathogens was 4 to 6 times higher in users than in non-users. Habitual use of bidet toilets aggravates vaginal microflora, either by depriving normal microflora or facilitating opportunistic infection of fecal bacteria and other microorganisms.

    Full Text Available Aim of the study was to estimate the incidence of unexpected premalignant gynecological lesions in women undergoing vaginal hysterectomy for utero-vaginal prolapse. Material and methods : Eighty women with asymptomatic utero-vaginal prolapse were included in this prospective study for vaginal hysterectomy after preoperative preparation and after written informed consent. Women included in this study were screened preoperatively by high vaginal swab, Pap smear, endometrial biopsy and trans-vaginal ultrasound. Surgically removed uteri and ovaries were sent for histopathological examination. Results of histopathological examination as gold standard were compared with conventional gynecological screening methods. Results : Histopathological examination of surgically removed uteri and ovaries after vaginal hysterectomy for uterovaginal prolapse showed abnormal findings in 61.25% (49/80 of studied cases (10 chronic cervicitis; 20 cervical intra-epithelial neoplasia-1 [CIN-1]; 5 CIN-2; 2 CIN-3; 10 simple endometrial hyperplasia without atypia and 2 simple serous ovarian cyst. Also, histopathological examination showed premalignant changes in 33.75% (27/80 of studied cases (20 CIN-1; 5 CIN-2 and 2 CIN-3, which mean 50% sensitivity of pre-operative Pap smear to detect premalignant cervical changes. Conclusions : Asymptomatic women with utero-vaginal prolapse may have associated premalignant lesions which may not be detected by conventional screening methods, and this should be explained preoperatively for women undergoing surgery, especially if conservative management was considered.

    To assess the distribution of vaginal microflora in healthy women and investigate their cognition of lower reproductive tract infection-related knowledge as well as personal hygiene habits and character of behavior in seeking medical treatment. Total of 1660 healthy women who had physical check-ups at the Medical Center of Renji Hospital were selected and received gynecologic examination, as well as routine examination, pH examination and bacterial culture of the vaginal discharge. In addition, 860 of them were randomly selected for questionnaire survey, in which reproductive tract infection -related knowledge and personal hygiene habits as well as behavior in seeking medical treatment were involved. Among the 1660 censused women, vaginal average pH was 4. 16 +/- 0.21. The positive rate of Candida in vaginal discharge routine examination was 3.86% (64/1660), which was lower than that in aerobes culture 7.71% (128/1660). Candida albicans was the most populous species 78.9% (101/128), followed by 7.8% (10/128) and 7.0% (9/128) for the Candida glabrata and Candida krusei respectively. The most populous species of vaginal microflora were hemolytic streptococcus A (63.80%, 1059/1660), Staphylococcus epidermidis (14.28%, 237/1660), and Enterococcus faecalis (D) group (11.44%, 190/1660). The questionnaire survey showed that 88.4% (760/860) of 860 women took active treatment when feeling unwell, 92.1% (792/860) of them had good hygiene practices, and only 21.2% (182/860) had the habit of vaginal douching. In addition, 50.0% (430/860) of them had the desire to obtain reproductive health knowledge through out-patient consultation. Vulvovaginal Candida disease ranks the first in all types of vaginitis, among which, Candida albicans is the most populous species followed by the Candida glabrata and Candida krusei. Hemolytic streptococcus A and Staphylococcus epidermidis are the most common species of vaginal microflora in healthy women. The censused women have high awareness of

    Full Text Available The human body is colonized by a vast number of microorganisms collectively referred to as the human microbiota. One of the main microbiota body sites is the female genital tract, commonly dominated by Lactobacillus spp., in approximately 70% of women. Each individual species can constitute approximately 99% of the ribotypes observed in any individual woman. The most frequently isolated species are Lactobacillus crispatus, Lactobacillus gasseri, Lactobacillus jensenii and Lactobacillus iners. Residing at the port of entry of bacterial and viral pathogens, the vaginal Lactobacillus species can create a barrier against pathogen invasion since mainly products of their metabolism secreted in the cervicovaginal fluid can play an important role in the inhibition of bacterial and viral infections. Therefore, a Lactobacillus-dominated microbiota appears to be a good biomarker for a healthy vaginal ecosystem. This balance can be rapidly altered during processes such as menstruation, sexual activity, pregnancy and various infections. An abnormal vaginal microbiota is characterized by an increased diversity of microbial species, leading to a condition known as bacterial vaginosis. Information on the vaginal microbiota can be gathered from the analysis of cervicovaginal fluid, by using the Nugent scoring or the Amsel’s criteria, or at the molecular level by investigating the number and type of Lactobacillus species. However, when translating this to the clinical setting, it should be noted that the absence of a Lactobacillus-dominated microbiota does not appear to directly imply a diseased condition or dysbiosis. Nevertheless, the widely documented beneficial role of vaginal Lactobacillus species demonstrates the potential of data on the composition and activity of lactobacilli as biomarkers for vaginal health. The substantiation and further validation of such biomarkers will allow the design of better targeted probiotic strategies.

    Full Text Available Rapid identification of yeast infections is helpful in prompt appropriate antifungal therapy. In the present study, the usefulness of chromogenic medium, slide culture technique and Vitek2 Compact (V2C has been analysed. A total of 173 clinical isolates of yeast species were included in the study. An algorithm to identify such isolates in routine clinical microbiology laboratory was prepared and followed. Chromogenic medium was able to identify Candida albicans, C. tropicalis, C. krusei, C. parapsilosis and Trichosporon asahii. Chromogenic medium was also helpful in identifying "multi-species" yeast infections. The medium was unable to provide presumptive identification of C. pelliculosa, C. utilis, C. rugosa, C. glabrata and C. hemulonii. Vitek 2 compact (V2C differentiated all pseudohypae non-producing yeast species. The algorithm followed was helpful in timely presumptive identification and final diagnosis of yeast infections, including multi-species yeast infections.

    This randomized controlled trial aimed to evaluate the outcomes of different vaginal cuff closure techniques in robotic-assisted total laparoscopic hysterectomy. Ninety women undergoing robotic-assisted total laparoscopic hysterectomy for benign disease were randomized to three vaginal cuff closure techniques: running 2.0 V-Lock™ (Arm 1), 0 Vicryl™ figure-of-eight (Arm 2), and running 0 Vicryl™ with Lapra-Ty(®) (Arm 3). Patients' records were reviewed for age, body mass index, smoking status and relevant co-morbidities. Operative times for vaginal closure and total length of surgery, estimated blood loss, and peri-operative complications were collected. Patients were evaluated at 2 and 6 weeks post-operatively, and interviewed 1year following surgery by a telephone survey. Outcomes evaluated were vaginal cuff dehiscence, pain, dyspareunia and bleeding. The study arms did not differ with respect to estimated blood loss (50mL in each arm; p=0.34), median vaginal cuff closure time (14.5, 12 and 13min, respectively; p=0.09) or readmission (p=0.55). In the 1-year follow-up (54/90 respondents; 60%), there were no significant differences among study arms for vaginal bleeding, cuff infection or dyspareunia. Only women belonging to arm 3 reported vaginal pain (0%, 0% and 23%, respectively; p=0.01). No cases of vaginal cuff dehiscence were observed. The type of closure technique has no significant impact on patient outcomes. In the absence of a clear advantage of one technique over the others, the decision regarding the preferred method to close the vaginal cuff in robotic-assisted total laparoscopic hysterectomy should be based on surgeons' preference and cost effectiveness.

    The opening of the mouse vaginal cavity to the skin is a postnatal tissue remodeling process that occurs at approximately five weeks of age for the completion of female genital tract maturation at puberty. The tissue remodeling process is primarily composed of a hormonally triggered apoptotic process predominantly occurring in the epithelium of the distal section of the vaginal cavity. However, the detailed mechanism underlying the apoptotic induction remains to be elucidated. In the present study, it was observed that the majority of BALB/c mice lacking the class 4 semaphorin, semaphorin 4D (Sema4D), developed imperforate vagina and hydrometrocolpos resulting in a perpetually unopened vaginal cavity regardless of a normal estrogen level comparable with that in wild‑type (WT) mice. Administration of β‑estradiol to infant Sema4D‑deficient (Sema4D‑/‑) mice did not induce precocious vaginal opening, which was observed in WT mice subjected to the same β‑estradiol administration, excluding the possibility that the closed vaginal phenotype was due to insufficient estrogen secretion at the time of vaginal opening. In order to assess the role of Sema4D in the postnatal vaginal tissue remodeling process, the expression of Sema4D and its receptor, plexin‑B1, was examined as well as the level of apoptosis in the vaginal epithelia of five‑week‑old WT and Sema4D‑/‑ mice. Immunohistochemical analyses confirmed the localization of Sema4D and plexin‑B1 in the mouse vaginal epithelia. Terminal deoxynucleotidyl transferase dUTP nick end labeling assay and immunohistochemistry detecting activated caspase‑3 revealed significantly fewer apoptotic cells in situ in the vaginal mucosa of five‑week‑old Sema4D‑/‑ mice compared with WT mice. The addition of recombinant Sema4D to Sema4D‑/‑ vaginal epithelial cells in culture significantly enhanced apoptosis of the vaginal epithelial cells, demonstrating the apoptosis‑inducing activity of Sema4D.

    The revised practice guideline by the Dutch College of General Practitioners (NHG) on vaginal discharge is intended to offer general practitioners a handle for management of vaginal complaints. Most general practitioners experience uncertainties in daily practice with respect to the diagnosis of vaginal discharge. In most cases history taking and physical examination fails to provide sufficient valuable information to arrive at a definite diagnosis. No further (microscopic) investigation is only permissible in a very obvious infection with Candida albicans. A recent onset of complaints of itching accompanied by white odourless discharge means a 70% chance of an infection with C. albicans. If the general practitioner also finds vulvar or vaginal inflammation and a nonhomogeneous fluor during examination the chance of an infection with C. albicans increases to 90%. In all other cases microscopic investigation is inevitable. This does not reflect an inadequacy of the NHG guideline but is a consequence of the limited diagnostic possibilities to arrive at a precise diagnosis.

    The concept of a prion as an infectious self-propagating protein isoform was initially proposed to explain certain mammalian diseases. It is now clear that yeast also has heritable elements transmitted via protein. Indeed, the “protein only” model of prion transmission was first proven using a yeast prion. Typically, known prions are ordered cross-β aggregates (amyloids). Recently, there has been an explosion in the number of recognized prions in yeast. Yeast continues to lead the way in understanding cellular control of prion propagation, prion structure, mechanisms of de novo prion formation, specificity of prion transmission, and the biological roles of prions. This review summarizes what has been learned from yeast prions. PMID:22879407

    The Golgi apparatus is an organelle that has been extensively studied in the model eukaryote, yeast. Its morphology varies among yeast species; the Golgi exists as a system of dispersed cisternae in the case of the budding yeast Saccharomyces cerevisiae, whereas the Golgi cisternae in Pichia pastoris and Schizosaccharomyces pombe are organized into stacks. In spite of the different organization, the mechanism of trafficking through the Golgi apparatus is believed to be similar, involving cisternal maturation, in which the resident Golgi proteins are transported backwards while secretory cargo proteins can stay in the cisternae. Questions remain regarding the organization of the yeast Golgi, the regulatory mechanisms that underlie cisternal maturation of the Golgi and transport machinery of cargo proteins through this organelle. Studies using different yeast species have provided hints to these mechanisms. © 2011 John Wiley & Sons A/S.

    The aim of the present investigation was to prepare and evaluate novel bioadhesive vaginal tablets containing clotrimazole loaded microspheres in order to provide long-term therapeutic activity at the site of infection. Tablets were prepared by incorporating drug loaded microspheres and using bioadhesive polymers hydroxypropylmethylcellulose, sodium carboxymethylcellulose and Carbopol. Microspheres were prepared by the spray drying technique using Eudragit RS-100 and Eudragit RL-100. Microspheres were characterized by SEM, DSC, FTIR, particle size analysis and evaluated for percentage yield, drug loading, encapsulation efficiency and in vitro drug release. To achieve bioadhesion to the mucosal tissue, optimized microspheres were incorporated into bioadhesive tablets and were evaluated for in vitro drug release, in vitro and in vivo mucoadhesion. FTIR and DSC studies showed that no chemical interaction occurred between the drug and polymers. The sphericity factor indicated that the prepared microspheres were spherical. Formulation Mt6 indicated a controlled in vitro drug release and good bioadhesive strength. The in vivo images confirmed the bioadhesion and retention property of tablets up to 24 h. The results indicated that this drug delivery system can be explored for controlled intravaginal drug release.

    Full Text Available Rational design of vaginal drug delivery formulations requires special attention to vehicle properties that optimize vaginal coating and retention. The aim of the present work was to perform a screening of mucoadhesive vaginal gels formulated with carbomer or carrageenan in binary combination with a second polymer (carbomer, guar or xanthan gum. The gels were characterised using in vitroadhesion, spreadability and leakage potential studies, as well as rheological measurements (stress and frequency sweep tests and the effect of dilution with simulated vaginal fluid (SVF on spreadability. Results were analysed using analysis of variance and multiple factor analysis. The combination of polymers enhanced adhesion of both primary gelling agents, carbomer and carrageenan. From the rheological point of view all formulations presented a similar behaviour, prevalently elastic and characterised by loss tangent values well below 1. No correlation between rheological and adhesion behaviour was found. Carbomer and carrageenan gels containing the highest percentage of xanthan gum displayed good in vitro mucoadhesion and spreadability, minimal leakage potential and high resistance to dilution. The positive results obtained with carrageenan-xanthan gum-based gels can encourage the use of natural biocompatible adjuvants in the composition of vaginal products, a formulation field that is currently under the synthetic domain.

    The majority of uncomplicated vulvovaginal complaints (e.g. bacterial vaginosis, vulvovaginal candidiasis, trichomoniasis) can be detected with uncomplicated basic infectiological tests and can usually be treated effectively without requiring further diagnostic procedures. Tests include measurement of vaginal pH, preparation and assessment of wet mount slides prepared from vaginal or cervical discharge, and the correct clinical and microbiological classification of findings. In Germany, at least in recent years, this has not been sufficiently taught or practiced. As new regulations on specialist gynecologic training in Germany are currently being drawn up, this overview provides basic information on gynecologic infectiology and summarizes clinically relevant aspects of recent microbiological findings on the physiology and pathology of vaginal flora. The clinical signs and symptoms of aerobic vaginitis, the pathogenesis of which is still not completely understood, are also reviewed. Finally, the symptoms, indications and risk factors for pelvic inflammatory disease (PID) are presented. In contrast to the above-listed infections, PID requires immediate culture of the pathogen from samples (e.g. obtained by laparoscopy) with microbiological diagnostic procedures carried out by specialist laboratories. A schematic summary of all pathologies discussed here is presented. PMID:26028693

    The need to verify participant behavior exists in any study in which behavior may affect outcomes. In vaginal microbicide trials, the act of having sex and the use of study products and condoms all affect the risk of acquiring HIV/sexually transmitted infections (STIs). Until now, these behaviors have been assessed using self-reports. But self-reports are limited by participant cooperation in answering questions, imperfect recall, and social desirability biases. Biomarkers are increasingly being used in medicine to reduce the time and resources needed to bring a drug to market. The use of biomarkers in vaginal microbicide trials has been proposed as a means of assessing factors that affect the risk of sexual acquisition of HIV/STIs, namely, the presence of preexisting infection, cervicovaginal inflammation, and the presence of HIV/STIs. Biomarkers for some of these already exist. What are needed are validated markers of behaviors that might affect risk, namely, markers for sexual behavior and for the use of study products and condoms. Validating and working out the logistics of collecting such markers in large trials will be a challenge. But finding objective markers for behavior may help improve adherence measurement during a trial and is a rate-limiting step in the field of vaginal microbicides. Resources and funding should be mobilized to develop and validate markers of sexual behavior and product use as a high priority in vaginal microbicide research.

    A skin and fascia flap from the medial thigh is proposed for vaginal and perineal reconstruction. Dissection, vascular injection, and radiographs of 20 fresh cadaver limbs uniformly demonstrated the presence of a communicating suprafascial vascular plexus in the medial thigh. Three to four nonaxial vessels were consistently found to enter the proximal plexus from within 5 cm of the perineum. Preservation of these vessels permitted reliable elevation of a 9 X 20 cm fasciocutaneous flap without using the gracilis muscle as a vascular carrier. Fifteen flaps in 13 patients were used for vaginal replacement and coverage of vulvectomy, groin, and ischial defects. Depending on the magnitude of the defect, simultaneous and independent elevation of the gracilis muscle provided additional vascularized coverage as needed. Our experience indicates that the medial thigh fasciocutaneous flap is a durable, less bulky, and potentially sensate alternative to the gracilis musculocutaneous flap for vaginal and perineal reconstruction.

    Trichomonas vaginalis infection is one of the most common sexually transmitted diseases in humans. T.vaginalis is a parasitic protozoan with a predilection for human urogenital tract and causative agent for vaginitis, cervicitis and urethritis in females. T.vaginalis infection is associated with risk of Human Immunodeficiency Virus infectivity and pregnancy complication. In this study, the prevalence of T.vaginalis in individuals who referred to public health units in Kashan city, Iran was investigated. This study was conducted on 970 women and 235 men who referred to 5 government health centers in Kashan, Iran during October 2012 to August 2013. Demographic information was collected as per the study protocol. Vaginal discharges and urine samples were obtained and examined by Trypticase-Yeast Extract Maltose (TYM) culture medium and wet-mount methods. The prevalence of T. vaginalis was determined using culture based method and wet-mount examinations. The overall prevalence of trichomonal infection was 2% (95% CI, 2±0.08). The age of infected individual was 33.7±9.4 years. All of those infected, were married housewives and 58.3% of them had primary school education. No statistical correlation was observed between clinical manifestations and parasitological results (p=0.8). This study showed a relatively low prevalence of T.vaginalis infection in the study population. Since the clinical signs of trichomoniasis are the same of other Sexually Transmitted Diseases (STDs), confirmatory laboratory tests are necessary. Due to adverse outcomes of disease, there is a great need for public education regarding implementation of personal hygienic measures and prevention of inappropriate sexual contacts.

    Full Text Available Bacterial vaginosis (BV is the most common vaginal disorder among reproductive age women. One clinical indicator of BV is a ‘fishy’ odor. This odor has been associated with increases in several biogenic amines (BAs that may serve as important biomarkers. Within the vagina, BA production has been linked to various vaginal taxa, yet their genetic capability to synthesize BAs is unknown. Using a bioinformatics approach, we show that relatively few vaginal taxa are predicted to be capable of producing BAs. Many of these taxa (Dialister, Prevotella, Parvimonas, Megasphaera, Peptostreptococcus, and Veillonella spp. are more abundant in the vaginal microbial community state type (CST IV, which is depleted in lactobacilli. Several of the major Lactobacillus species (L. crispatus, L. jensenii, and L. gasseri were identified as possessing gene sequences for proteins predicted to be capable of putrescine production. Finally, we show in a small cross sectional study of 37 women that the BAs putrescine, cadaverine and tyramine are significantly higher in CST IV over CSTs I and III. These data support the hypothesis that BA production is conducted by few vaginal taxa and may be important to the outgrowth of BV-associated (vaginal dysbiosis vaginal bacteria.

    Full Text Available Aim. The aim of this study is to introduce a new technique, anterior vaginal wall darn (AVWD, which has not been used before to repair the anterior vaginal wall prolapse, a common problem among women. Materials and Methods. Forty-five women suffering from anterior vaginal wall prolapse were operated on with a new technique. The anterior vaginal wall was detached by sharp and blunt dissection via an incision beginning from the 1 cm proximal aspect of the external meatus extending to the vaginal apex, and the space between the tissues that attach the lateral walls of the vagina to the arcus tendineus fascia pelvis (ATFP was then darned. Preoperation and early postoperation evaluations of the patients were conducted and summarized. Results. Data were collected six months after operation. Cough stress test (CST, Pelvic Organ Prolapse Quantification (POP-Q evaluation, Incontinence Impact Questionnaire (IIQ-7, and Urogenital Distress Inventory (UDI-6 scores indicated recovery. According to the early postoperation results, all patients were satisfied with the operation. No vaginal mucosal erosion or any other complications were detected. Conclusion. In this initial series, our short-term results suggested that patients with grade II-III anterior vaginal wall prolapsus might be treated successfully with the AVWD method.

    To investigate the clinical characteristics, diagnosis and treatment of vaginal intraepithelial neoplasia (VAIN). A retrospective study was made of 6 patients with VAIN, who were hospitalized at Peking Union Medical College Hospital from 1980 to 2006. Five cases had a history of hysterectomy, two of whom were because of cervical intraepithelial neoplasia (CIN) or invasive cervical cancer. Four cases had the infection of high-risk oncogenic human papillomaviruses detected with hybrid capture II (HC-II), the other two had no record. In all patients the VAIN lesions were within the upper one third of the vagina. They were all diagnosed by colposcopic examination and directed biopsy after the abnormal cytology by thinprep cytology test (TCT). Six cases of VAIN II-III were treated by excisional surgery. One case had residual lesion and had another surgery 3 months after the first one. Two patients obtained remission at one-year follow-up, three had abnormal cytology by TCT 6 months after surgery, and one had abnormal cytology by TCT at six-month follow-up but normal at one-year follow-up. A history of CIN is the main risk factor for VAIN, so routine vaginal cytology is needed for the patients after hysterectomy due to CIN. Cytology, colposcopic examination and directed biopsy are the mainstays of VAIN diagnosis. Excisional surgery is recommended for the patients with VAIN II-III. Long term follow-up is necessary after treatment.

    Sucrose gel was used to treat bacterial vaginosis in a phase III clinical trial. However, the changes of vaginal flora after treatment were only examined by Nugent score in that clinical trial, While the vaginal microbiota of rhesus macaques is characterized by anaerobic, Gram-negative bacteria, few lactobacilli, and pH levels above 4.6, similar to the microbiota of patients with bacterial vaginosis. This study is aimed to investigate the change of the vaginal microbiota of rehsus macaques after topical use of sucrose gel to reveal more precisely the bacterial population shift after the topical application of sucrose gel. Sixteen rhesus macaques were treated with 0.5 g sucrose gel vaginally and three with 0.5 g of placebo gel. Vaginal swabs were collected daily following treatment. Vaginal pH levels and Nugent scores were recorded. The composition of the vaginal micotbiota was tested by V3∼V4 16S rDNA metagenomic sequencing. Dynamic changes in the Lactobacillus genus were analyzed by qPCR. The vaginal microbiota of rhesus macaques are dominated by anaerobic Gram-negative bacteria, with few lactobacilli and high pH levels above 4.6. After five days' treatment with topical sucrose gel, the component percentage of Lactobacillus in vaginal microbiota increased from 1.31% to 81.59%, while the component percentage of Porphyromonas decreased from 18.60% to 0.43%, Sneathia decreased from 15.09% to 0.89%, Mobiluncus decreased from 8.23% to 0.12%, etc.. The average vaginal pH values of 16 rhesus macaques of the sucrose gel group decreased from 5.4 to 3.89. There were no significant changes in microbiota and vaginal pH observed in the placebo group. Rhesus macaques can be used as animal models of bacterial vaginosis to develop drugs and test treatment efficacy. Furthermore, the topical application of sucrose gel induced the shifting of vaginal flora of rhesus macaques from a BV kind of flora to a lactobacilli-dominating flora. Copyright © 2015 The Authors.

    Gardnerella vaginalis is an important component of the human vaginal microflora. It is proposed to play a key role in the pathogenesis of bacterial vaginosis (BV), the most common vaginal condition. Here we describe the development, validation and comparative analysis of a novel molecular approach capable of G. vaginalis identification, quantification and subtyping in noncultured vaginal specimens. Using two quantitative PCR (qPCR) assays, we analysed G. vaginalis bacterial loads and clade distribution in 60 clinical vaginal-swab samples. A very high pathogen prevalence was revealed by species-specific qPCR not only among BV patients (100 %), but also in healthy women (97 %), although the G. vaginalis concentration was significantly lower in non-BV samples. G. vaginalis clades identified in vaginal specimens by subtyping multiplex qPCR, which targets four clade-specific genetic markers, had frequencies of 53 % for clade 1, 25 % for clade 2, 32 % for clade 3 and 83 % for clade 4. Multiple clades were found in 70 % of samples. Single G. vaginalis clades were represented by clade 1 and clade 4 in 28 % of specimens. A positive association with BV was shown for clade 1 and clade 3, while clade 2 was positively associated with intermediate vaginal microflora, but not with BV. Clade 4 demonstrated no correlation with the disorder. The presence of multiple clades had a high positive association with BV, whereas G. vaginalis identified as a single clade was negatively linked with the condition. Polyclonal G. vaginalis infection may be a risk factor for BV.

    Recurring vulvovaginal candidosis (RVVC) is a common vaginal discharge, affecting 75% of all women at least once in their life. In 5% of these women, this infection is recurring. Recent studies have focused on determining the importance of vaginal-associated immunity. To investigate the effects of immune mediators and the probability of an immune defect as well as localized allergic responses due to candida, we examined the cytokines IL-4, IL-5, IL-13 as well as prostaglandin E(2) (PgE(2)), candida-specific IgE and total-IgE in patients with a clinical diagnosis of RVVC. In 104 symptomatic and 41 asymptomatic patients, regarding clinical symptoms of RVVC, vaginal fluids were measured by ELISA for the immune mediators IL-4, IL-5, IL-13, PgE(2), candida-specific IgE and total-IgE. Polymerase chain reactions as well as culture were used for candida detection. Concerning IL-5, IL-13 and total-IgE no statistically significant difference was found. Those women with a history of RVVC and who were currently symptomatic had elevated concentrations of IL-4 (pvaginal fluids compared to women with no clinical symptoms. Those three interleukins showed no significant differences between symptomatic patients who were positive or negative for Candida albicans or Candida glabrata. These findings indicate that women with clinical vaginal symptoms have a localized vaginal immunosuppression which might be the cause of their symptoms. Greatly elevated vaginal PgE(2) levels can be a consequence of a localized allergic response. An allergic reaction to candida components may be the cause of the allergic response in those women with high levels of candida-specific IgE. In women with elevated PgE(2), treatment with an antihistamine or prostaglandin synthesis inhibitor might be beneficial.

    Full Text Available Objective: To determine the prevalence of trichomonal infection in HIV/AIDS and non-HIV control group of patients in a population of women with abnormal vaginal discharge. Methods: We conducted a simple cross-sectional study. Primary health care centers in Jos metropolis and Jos University Teaching Hospital, during December 2006 to December 2007. Seven hundred high vaginal swabs were collected; 350 from HIV positive and another 350 from HIV-negative control group of patients with abnormal vaginal discharge attending primary health care centers in Jos metropolis and analysed for microscopy and culture in Jos University Teaching Hospital. Data on epidemiologic indices from the patients, using structured interviewer-administered questionnaires were collected. Results: The rate of trichomoniasis among all participants in the study was 17% (n=120/700. The prevalence rate of trichomoniasis among persons with HIV was 24% while it was found to be 10.3% among HIV negative controls. The difference was statistically significant (氈 2 =23.172; df=1; P<0.05. The rate of co-infection of Trichomonas vaginalis (T. vaginalis in bacterial vaginosis was 42% (n=50/120, while it was 24% (n=29/120 in candidiasis. The singles had a 35% high rate of trichomonal infection. The infected women had a median age of 26 years, and a median number of 3 intra-vaginal sex partners per week. Conclusions: There was a significant statistical difference in prevalence of T. vaginalis between HIV/AIDS group and nonHIV(control group of patients in the study (P<0.05. Local HIV prevention strategies should target such women with trichomonal infection for intervention efforts, especially in HIV endemic area of sub-continent of Africa to further reduce the burden of HIV in the population.

    Full Text Available Vaginal formulations for the prevention of sexually transmitted infections are currently gaining importance in drug development. Polysaccharides, such as chitosan and carrageenan, which have good binding capacity with mucosal tissues, are now included in vaginal delivery systems. Marine polymer-based vaginal mucoadhesive solid formulations have been developed for the controlled release of acyclovir, which may prevent the sexual transmission of the herpes simplex virus. Drug release studies were carried out in two media: simulated vaginal fluid and simulated vaginal fluid/simulated seminal fluid mixture. The bioadhesive capacity and permanence time of the bioadhesion, the prepared compacts, and compacted granules were determined ex vivo using bovine vaginal mucosa as substrate. Swelling processes were quantified to confirm the release data. Biocompatibility was evaluated through in vitro cellular toxicity assays, and the results showed that acyclovir and the rest of the materials had no cytotoxicity at the maximum concentration tested. The mixture of hydroxyl-propyl-methyl-cellulose with chitosan- or kappa-carrageenan-originated mucoadhesive systems that presented a complete and sustained release of acyclovir for a period of 8–9 days in both media. Swelling data revealed the formation of optimal mixed chitosan/hydroxyl-propyl-methyl-cellulose gels which could be appropriated for the prevention of sexual transmission of HSV.

    Administering intravenous antibiotics during labor to women at risk for transmitting Group B Streptococcus (GBS) can prevent infections in newborns. However, the impact of intrapartum antibiotic prophylaxis on mothers' microbial community composition is largely unknown. We compared vaginal microbial composition in pregnant women experiencing preterm birth at ≤ 32 weeks gestation that received intrapartum antibiotic prophylaxis with that in controls. Microbiota in vaginal swabs collected shortly before delivery from GBS positive women that received penicillin intravenously during labor or after premature rupture of membranes was compared to controls. Microbiota was analyzed by 16S rRNA sequencing using the PGM Ion Torrent to determine the effects of penicillin use during hospitalization and GBS status on its composition. Penicillin administration was associated with an altered vaginal microbial community composition characterized by increased microbial diversity. Lactobacillus sp. contributed only 13.1% of the total community in the women that received penicillin compared to 88.1% in the controls. Streptococcus sp. were present in higher abundance in GBS positive woman compared to controls, with 60% of the total vaginal microbiota in severe cases identified as Streptococcus sp. Vaginal communities of healthy pregnant women were dominated by Lactobacillus sp. and contained low diversity, while Group B Streptococcus positive women receiving intrapartum antibiotic prophylaxis had a modified vaginal microbiota composition with low abundance of Lactobacillus but higher microbial diversity.

    The objective of this work was to establish the in vitro and in vivo inhibition of post-harvest pathogenic moulds by yeasts in order to make a biocontrol product. Post-harvest pathogenic moulds Penicillium digitatum, P. italicum, P. ulaiense, Phyllosticta sp., Galactomyces geotrichum and yeasts belonging to genera Brettanomyces, Candida, Cryptococcus, Kloeckera, Pichia, Rhodotorula were isolated from citrus fruits. Some yeasts strains were also isolated from other sources. The yeasts were identified by their macro and micro-morphology and physiological tests. The in vitro and in vivo activities against P. digitatum or P. ulaiense were different. Candida cantarellii and one strain of Pichia subpelliculosa produced a significant reduction of the lesion area caused by the pathogenic moulds P. digitatum and P. ulaiense, and could be used in a biocontrol product formulation.

    Nitriles and amides are widely distributed in the biotic and abiotic components of our ecosystem. Nitrile form an important group of organic compounds which find their applications in the synthesis of a large number of compounds used as/in pharmaceutical, cosmetics, plastics, dyes, etc>. Nitriles are mainly hydro-lyzed to corresponding amide/acid in organic chemistry. Industrial and agricultural activities have also lead to release of nitriles and amides into the environment and some of them pose threat to human health. Biocatalysis and biotransformations are increasingly replacing chemical routes of synthesis in organic chemistry as a part of ‘green chemistry’. Nitrile metabolizing organisms or enzymes thus has assumed greater significance in all these years to convert nitriles to amides/ acids. The nitrile metabolizing enzymes are widely present in bacteria, fungi and yeasts. Yeasts metabolize nitriles through nitrilase and/or nitrile hydratase and amidase enzymes. Only few yeasts have been reported to possess aldoxime dehydratase. More than sixty nitrile metabolizing yeast strains have been hither to isolated from cyanide treatment bioreactor, fermented foods and soil. Most of the yeasts contain nitrile hydratase-amidase system for metabolizing nitriles. Transformations of nitriles to amides/acids have been carried out with free and immobilized yeast cells. The nitrilases of Torulopsis candida>and Exophiala oligosperma>R1 are enantioselec-tive and regiospecific respectively. Geotrichum>sp. JR1 grows in the presence of 2M acetonitrile and may have potential for application in bioremediation of nitrile contaminated soil/water. The nitrilase of E. oligosperma>R1 being active at low pH (3-6) has shown promise for the hydroxy acids. Immobilized yeast cells hydrolyze some additional nitriles in comparison to free cells. It is expected that more focus in future will be on purification, characterization, cloning, expression and immobilization of nitrile metabolizing

    Helicobacter pylori (H. pylori) are resistant to hostile gastric environments and antibiotic therapy, reflecting the possibility that they are protected by an ecological niche, such as inside the vacuoles of human epithelial and immune cells. Candida yeast may also provide such an alternative niche, as fluorescently labeled H. pylori were observed as fast-moving and viable bacterium-like bodies inside the vacuoles of gastric, oral, vaginal and foodborne Candida yeasts. In addition, H. pylori-specific genes and proteins were detected in samples extracted from these yeasts. The H. pylori present within these yeasts produce peroxiredoxin and thiol peroxidase, providing the ability to detoxify oxygen metabolites formed in immune cells. Furthermore, these bacteria produce urease and VacA, two virulence determinants of H. pylori that influence phago-lysosome fusion and bacterial survival in macrophages. Microscopic observations of H. pylori cells in new generations of yeasts along with amplification of H. pylori-specific genes from consecutive generations indicate that new yeasts can inherit the intracellular H. pylori as part of their vacuolar content. Accordingly, it is proposed that yeast vacuoles serve as a sophisticated niche that protects H. pylori against the environmental stresses and provides essential nutrients, including ergosterol, for its growth and multiplication. This intracellular establishment inside the yeast vacuole likely occurred long ago, leading to the adaptation of H. pylori to persist in phagocytic cells. The presence of these bacteria within yeasts, including foodborne yeasts, along with the vertical transmission of yeasts from mother to neonate, provide explanations for the persistence and propagation of H. pylori in the human population. This Topic Highlight reviews and discusses recent evidence regarding the evolutionary adaptation of H. pylori to thrive in host cell vacuoles.

    The proper evaluation of the pelvic floor muscles (PFM) is essential for choosing the correct treatment. Currently, there is no gold standard for the assessment of female PFM function. To determine the correlation between vaginal palpation, vaginal squeeze pressure, and electromyographic and ultrasonographic variables of the female PFM. This cross-sectional study evaluated 80 women between 18 and 35 years of age who were nulliparous and had no pelvic floor dysfunction. PFM function was assessed based on digital palpation, vaginal squeeze pressure, electromyographic activity, bilateral diameter of the bulbocavernosus muscles and the amount of bladder neck movement during voluntary PFM contraction using transperineal bi-dimensional ultrasound. The Pearson correlation was used for statistical analysis (ppalpation, vaginal squeeze pressure, and electromyographic and ultrasonographic variables of the PFM in nulliparous women. The strong correlation between digital palpation and PFM contraction pressure indicated that perineometry could easily be replaced by PFM digital palpation in the absence of equipment.

    In the baker's yeast Saccharomyces cerevisiae, cell-cell adhesion (``flocculation'') is conferred by a family of lectin-like proteins known as the flocculin (Flo) proteins. Knowledge of the adhesive and mechanical properties of flocculins is important for understanding the mechanisms of yeast adhesion, and may help controlling yeast behaviour in biotechnology. We use single-molecule and single-cell atomic force microscopy (AFM) to explore the nanoscale forces engaged in yeast flocculation, focusing on the role of Flo1 as a prototype of flocculins. Using AFM tips labelled with mannose, we detect single flocculins on Flo1-expressing cells, showing they are widely exposed on the cell surface. When subjected to force, individual Flo1 proteins display two distinct force responses, i.e. weak lectin binding forces and strong unfolding forces reflecting the force-induced extension of hydrophobic tandem repeats. We demonstrate that cell-cell adhesion bonds also involve multiple weak lectin interactions together with strong unfolding forces, both associated with Flo1 molecules. Single-molecule and single-cell data correlate with microscale cell adhesion behaviour, suggesting strongly that Flo1 mechanics is critical for yeast flocculation. These results favour a model in which not only weak lectin-sugar interactions are involved in yeast flocculation but also strong hydrophobic interactions resulting from protein unfolding.

    In prolapse surgery several surgical techniques are available. The different open, laparoscopic and vaginal approaches are distinguished by distinct success and relapse rates and operation-specific complications. A safe and optimal therapeutic pelvic floor surgery should be based on the three support levels according to DeLancy and be individually adjusted for every patient. The vaginal approach may be used for all kinds of female genital prolapse and is a comparatively less invasive technique with a short time of convalescence. Apart from stress incontinence there is no need for synthetic meshes in primary approaches and excellent results with low complication and relapse rates can be achieved. An uncritical application of synthetic material is to be avoided in vaginal repair at all times. Abdominal surgical techniques, both open and laparoscopic, present their strengths in the therapeutic approach to level 1 defects or stress incontinence. They provide excellent functional and anatomical corrections and low relapse rates. Abdominally inserted meshes have lower complication rates than vaginal ones.

  17. Antiretroviral pre-exposure prophylaxis prevents vaginal transmission of HIV-1 in humanized BLT mice.

    Directory of Open Access Journals (Sweden)

    Paul W Denton

    2008-01-01

    Full Text Available Worldwide, vaginal transmission now accounts for more than half of newly acquired HIV-1 infections. Despite the urgency to develop and implement novel approaches capable of preventing HIV transmission, this process has been hindered by the lack of adequate small animal models for preclinical efficacy and safety testing. Given the importance of this route of transmission, we investigated the susceptibility of humanized mice to intravaginal HIV-1 infection.We show that the female reproductive tract of humanized bone marrow-liver-thymus (BLT mice is reconstituted with human CD4+ T and other relevant human cells, rendering these humanized mice susceptible to intravaginal infection by HIV-1. Effects of HIV-1 infection include CD4+ T cell depletion in gut-associated lymphoid tissue (GALT that closely mimics what is observed in HIV-1-infected humans. We also show that pre-exposure prophylaxis with antiretroviral drugs is a highly effective method for preventing vaginal HIV-1 transmission. Whereas 88% (7/8 of BLT mice inoculated vaginally with HIV-1 became infected, none of the animals (0/5 given pre-exposure prophylaxis of emtricitabine (FTC/tenofovir disoproxil fumarate (TDF showed evidence of infection (Chi square = 7.5, df = 1, p = 0.006.The fact that humanized BLT mice are susceptible to intravaginal infection makes this system an excellent candidate for preclinical evaluation of both microbicides and pre-exposure prophylactic regimens. The utility of humanized mice to study intravaginal HIV-1 transmission is particularly highlighted by the demonstration that pre-exposure prophylaxis can prevent intravaginal HIV-1 transmission in the BLT mouse model.

    The risk of opportunistic infections caused by non-Candida yeasts and yeast-like fungi is increasingly common, mainly in immunocompromised patients. Appropriate first-line therapy has not been defined and standardized, mainly due to the low number of cases reported. To improve empirical treatment guidelines, we describe the susceptibility profile to fluconazole and voriconazole of 176 non-Candida yeasts and yeast-like fungi collected from hospitals in Piedmont, North West Italy from January 2009 to December 2013. The results showed that most isolates are susceptible to voriconazole (94%), but less susceptible to fluconazole (78%), suggesting that voriconazole could be used as first-line therapy in infections caused by these fungi.

    2010-03-01

    Full Text Available Urogenital infections affect millions of people every year worldwide. The treatment of these diseases usually requires the use of antimicrobial agents, and more recently, the use of probiotic lactic acid bacteria (LAB cultures for the management of vaginal infections has been extensively studied. In this work, 11 vaginal lactobacilli isolates, previously obtained from healthy patients, were studied to screen microorganisms with probiotic properties against Candida spp. The LAB were tested for their ability of auto-aggregation, coaggregation with C. albicans, C. glabrata, C. krusei, and C. tropicalis, adhesion to Caco-2 epithelial cells and production of lactic acid and hydrogen peroxide (H2O2. All lactobacilli isolates tested were able to auto-aggregate (ranging from 25.3% to 75.4% assessed at 4 hours of incubation and to co-aggregate with the four Candida species into different degrees; among them L. crispatus showed the highest scores of coaggregation. The highest amount of lactic acid was produced by L. salivarius (13.9 g/l, followed by L. johnsonii (6.5 g/l, L. acidophilus (5.5 g/l, and L. jensenii (5.4 g/l. All isolates produced H2O2 , but the highest levels (3 -10 mg/l were observed for L. acidophilus, L. crispatus, L. gasseri, L. johnsonii, and L. vaginalis. Only L. agilis, L. jensenii, L. johnsonii and L. ruminus were able to adhere to epithelial Caco-2 cells. Among the isolates evaluated, L agilis, L. jensenii, L. johnsonii, and L. ruminus exhibited simultaneously several desirable properties as potential probiotic strains justifying future studies to evaluate their technological properties in different pharmaceutical preparations for human use.

    NK cell responses to HIV/SIV infection have been well studied in acute and chronic infected patients/monkeys, but little is known about NK cells during viral transmission, particularly in mucosal tissues. In this article, we report a systematic study of NK cell responses to high-dose vaginal exposure to SIVmac251 in the rhesus macaque female reproductive tract (FRT). Small numbers of NK cells were recruited into the FRT mucosa following vaginal inoculation. The influx of mucosal NK cells preceded local virus replication and peaked at 1 wk and, thus, was in an appropriate time frame to control an expanding population of infected cells at the portal of entry. However, NK cells were greatly outnumbered by recruited target cells that fuel local virus expansion and were spatially dissociated from SIV RNA+ cells at the major site of expansion of infected founder populations in the transition zone and adjoining endocervix. The number of NK cells in the FRT mucosa decreased rapidly in the second week, while the number of SIV RNA+ cells in the FRT reached its peak. Mucosal NK cells produced IFN-γ and MIP-1α/CCL3 but lacked several markers of activation and cytotoxicity, and this was correlated with inoculum-induced upregulation of the inhibitory ligand HLA-E and downregulation of the activating receptor CD122/IL-2Rβ. Examination of SIVΔnef-vaccinated monkeys suggested that recruitment of NK cells to the genital mucosa was not involved in vaccine-induced protection from vaginal challenge. In summary, our results suggest that NK cells play, at most, a limited role in defenses in the FRT against vaginal challenge. Copyright © 2014 by The American Association of Immunologists, Inc.

  1. Atrophic Vaginitis in Breast Cancer Survivors: A Difficult Survivorship Issue

    Directory of Open Access Journals (Sweden)

    Joanne Lester

    2015-03-01

    Full Text Available Management of breast cancer includes systematic therapies including chemotherapy and endocrine therapy can lead to a variety of symptoms that can impair the quality of life of many breast cancer survivors. Atrophic vaginitis, caused by decreased levels of circulating estrogen to urinary and vaginal receptors, is commonly experienced by this group. Chemotherapy induced ovarian failure and endocrine therapies including aromatase inhibitors and selective estrogen receptor modulators can trigger the onset of atrophic vaginitis or exacerbate existing symptoms. Symptoms of atrophic vaginitis include vaginal dryness, dyspareunia, and irritation of genital skin, pruritus, burning, vaginal discharge, and soreness. The diagnosis of atrophic vaginitis is confirmed through patient-reported symptoms and gynecological examination of external structures, introitus, and vaginal mucosa. Lifestyle modifications can be helpful but are usually insufficient to significantly improve symptoms. Non-hormonal vaginal therapies may provide additional relief by increasing vaginal moisture and fluid. Systemic estrogen therapy is contraindicated in breast cancer survivors. Continued investigations of various treatments for atrophic vaginitis are necessary. Local estrogen-based therapies, DHEA, testosterone, and pH-balanced gels continue to be evaluated in ongoing studies. Definitive results are needed pertaining to the safety of topical estrogens in breast cancer survivors.

    2016-01-01

    The aim of this study was to evaluate the concept of female Dhat syndrome characterized by the complaint of nonpathological vaginal discharge in association with somatic, anxiety, and depressive symptoms. A total of 26 female subjects with nonpathological vaginal discharge along with depressive and somatic complaints were assessed on a self-rated questionnaire modified from Comprehensive Questionnaire for Assessment of Dhat Syndrome designed for males. They were also assessed for psychiatric comorbidity as per ICD-10. All female subjects received an ICD-10 psychiatric diagnosis, with somatoform/dissociative disorder (57.7%) being the most common. The mean age of onset of vaginal discharge was 24.6 (standard deviation - 7.0) years, noted every day or for 2-3 times per week by more than two-third of the participants. Two-fifth (61.5%) of the women described it as a milky discharge. The most common reason reported for passage of vaginal discharge was that of urinary infection or problems of urinary tract infections (42.3%) followed by vaginal infection/disease (34.6%). More than half (53.8%) of the subjects considered vaginal discharge to be responsible for weakness in the body, weakness in stamina and thinness of physique, while slightly more than two-third (69.2%) of them reported bodily weakness and sleep disturbances. Overall the clinical picture in females was similar to male patients with Dhat syndrome on most of the account. Subgroup of patients with vaginal discharge attribute their somatic and mental symptoms to the passage of whitish vaginal discharge and are distressed due to the same. The clinical picture is similar to Dhat syndrome in males. There is a need to recognize female variant of Dhat syndrome as a culture-bound syndrome. Identification of the same may help in managing this subgroup of patients seeking help from the gynecologists for their nonpathological vaginal discharge or from mental health professionals for their symptoms of common mental

    The aim of this work was to identify the predominant fungal species present at vaginal site in different healthy cats including households, stray and cats in industrial dairy cattle herds. Fungal isolates of vaginal fluids of 100 cats were collected using the sterilized cotton swabs from discharges of vagina. The isolates were identified according to their morphological characteristics and biochemical profile. Were included 34%, 33% and 33% households, stray cats and cats of industrial dairy cattle herds of Mashhad-Iran, respectively. They were short hair cats. Vaginal fungi were isolated from 69% of feline population. Fungal isolates were obtained from vagina of 22%, 25% and 22% of households, stray cats and cats of industrial dairy cattle herds, respectively. There were no significant differences among the cats. The highest fungal agent was recovered in cats of 1-2 years old. Twenty two different isolates were recovered in this study. The most frequently recovered species samples were Penicillum spp. (11%) followed by Aspergillus section Nidulanti (4%). However, the vagina of healthy cats could be contaminated by 2-4 different fungal agents. It is concluded that fungal infections can occur in vaginal cavity of different healthy kinds of cats.

    The objective was to compare three diagnostic approaches for intrauterine infection and inflammation: scoring of vaginal contents; quantification of percentage of nucleated cells that were polymorphonuclear leukocytes (PMN) following endometrial cytology; and intra-uterine bacteriology. Dairy cows (n = 303) were examined twice, Days 28 (D28) and 42 (D42), where Day 0 = day of calving. Associations between gross vaginal inflammation scores, uterine cytology, and bacteriology, and subsequent reproductive performance were examined using multivariable models. There was fair agreement at D28 (Kappa = 0.29), but only slight agreement at D42 (Kappa vaginal inflammation score. Cows were categorized as having PMN% in the highest quartile (H), or not (L), at both D28 and D42; therefore, cows were categorized as PMNLL, PMNLH, PMNHL, or PMNHH. Cows in the highest PMN% quartile at both time periods were slower to conceive (P vaginal inflammation score. Cows in the highest quartile for PMN% at both D28 and D42 had lower pregnancy rates, took longer to conceive, and had a lower milk yield than those in the lower PMN% categories.

    Previous studies suggest that larger sutures increase the risk of complications after prolapse surgery. This study aimed to assess whether multifilament sutures increased complications compared with monofilament sutures. A series of 100 women with 2/0 multifilament suture were matched by operation to a previous cohort when a size 2/0 monofilament suture was used. Offensive vaginal discharge was more common in the multifilament than in the monofilament group (24% vs. 12%; p = 0.04). However, there was no increased requirement to seek advice from a health professional (33% vs. 25%; p = 0.27) or to require antibiotics. Vaginal bleeding (10% vs. 5%; p = 0.28) and urinary infection (2% vs. 5%; p = 0.44) were statistically no more common in the multifilament 2/0 compared with the monofilament 2/0 group. Multifilament sutures used for closure of the vaginal skin are associated with a clinically non-significant higher incidence of vaginal discharge in the early post-operative period.

    Escherichia coli is one of the main causes of uncomplicated urinary tract infections and responsible of vaginal infections. Lactobacilli can inhibit this pathogen by the production of antimicrobial substances as organic acids, hydrogen peroxide and/or bacteriocins. The aim of this work was to study the effects of beneficial vaginal lactobacilli on E. coli through in vitro experiments. The inhibitory activity of three vaginal Lactobacillus strains against E. coli was assessed using the agar plate diffusion. Moreover, the effect of Lactobacillus reuteri CRL (Centro de Referencia para Lactobacilos Culture Collection) 1324 on the adhesion and internalization capabilities of E. coli was studied on HeLa cells. Two Lactobacillus strains inhibited the growth of the pathogens by production of organic acids. L. reuteri CRL 1324 reduced the adhesion and internalization of E. coli 275 into HeLa cells. The results obtained suggest that L. reuteri CRL 1324 can be considered as a probiotic candidate for further in vivo studies for the prevention or treatment of urinary tract infections caused by E. coli.

    this is covered by another Cochrane review. However, studies where vaginal examinations were used within the context of the partogram were included if the studies were randomised according to the vaginal examination component. Three review authors assessed the studies for inclusion in the review. Two authors undertook independent data extraction and assessed the risk of bias of each included study. A third review author also checked data extraction and risk of bias. Data entry was checked. We found two studies that met our inclusion criteria but they were of unclear quality. One study, involving 307 women, compared vaginal examinations with rectal examinations, and the other study, involving 150 women, compared two-hourly with four-hourly vaginal examinations. Both studies were of unclear quality in terms of risk of selection bias, and the study comparing the timing of the vaginal examinations excluded 27% (two hourly) to 28% (four hourly) of women after randomisation because they no longer met the inclusion criteria.When comparing routine vaginal examinations with routine rectal examinations to assess the progress of labour, we identified no difference in neonatal infections requiring antibiotics (risk ratio (RR) 0.33, 95% confidence interval (CI) 0.01 to 8.07, one study, 307 infants). There were no data on the other primary outcomes of length of labour, maternal infections requiring antibiotics and women's overall views of labour. The study did show that significantly fewer women reported that vaginal examination was very uncomfortable compared with rectal examinations (RR 0.42, 95% CI 0.25 to 0.70, one study, 303 women). We identified no difference in the secondary outcomes of augmentation, caesarean section, spontaneous vaginal birth, operative vaginal birth, perinatal mortality and admission to neonatal intensive care.Comparing two-hourly vaginal examinations with four-hourly vaginal examinations in labour, we found no difference in length of labour (mean

    Manteca is a traditional milk product of southern Italy produced from whey deriving from Caciocavallo Podolico cheese-making. This study was undertaken to obtain more information about the microbiological properties of this product and particularly about the presence, metabolic activities, and technological significance of the different yeast species naturally occurring in Manteca. High numbers of yeasts were counted after 7 days ripening (10(4)-10(5) cfu g(-1)) and then decreased to 10(2) at the end. A total of 179 isolates were identified and studied for their phenotypic and genotypic characteristics. The most frequently encountered species were Trichosporon asahii (45), Candida parapsilosis (33), Rhodotorula mucilaginosa (32), Candida inconspicua (29). Some of these yeasts showed lipolytic activity (32 strains) and proteolytic activity (29 strains), NaCl resistance up to 10% and growth up to 45 degrees C (42 strains). Biogenic amines were formed by proteolytic strains, in particular phenylethylamine, putrescine and spermidine. Spermidine was produced by all the yeasts tested in this work, but only Trichosporon produced a great quantity of this compound. Histamine was not detectable. Caseinolytic activity was common to almost all strains, corresponding to the ability to efficiently split off amino-terminal amino acids. The highest and most constant activity expressed by all species was X-prolyl-dipeptidyl aminopeptidase. The findings suggest that the presence of yeasts may play a significant role in justifying interactions with lactic acid bacteria, and consequently with their metabolic activity in the definition of the peculiar characteristics of Manteca cheese.

In addition, the accumulating sequence data provide...... that the minimum number of genes from each species that need to be compared to produce a reliable phylogeny is about 20. Yeast has also become an attractive model to study speciation in eukaryotes, especially to understand molecular mechanisms behind the establishment of reproductive isolation. Comparison...... of closely related species helps in gene annotation and to answer how many genes there really are within the genomes. Analysis of non-coding regions among closely related species has provided an example of how to determine novel gene regulatory sequences, which were previously difficult to analyse because...

    This paper focuses on biofilms of Lactobacillus spp. - a type of normal flora isolated from healthy human vaginas of women of childbearing age; thereupon, it broadens the research scope of investigation of vaginal normal flora. The static slide culture method was adopted to foster biofilms, marked by specific fluorescence staining. Laser scanning confocal and scanning electron microscopy were used to observe the microstructure of the biofilms. Photographs taken from the microstructure were analysed to calculate the density of the biofilms. The body of Lactobacillus spp., though red, turned yellow when interacting with the green extracellular polysaccharides. The structure of the biofilm and aquaporin within the biofilm were imaged. Lactobacillus density increases over time. This study provides convincing evidence that Lactobacillus can form biofilms and grow over time in vitro. This finding establishes an important and necessary condition for selecting proper strains for the pharmaceutics of vaginal ecology.

    Purpose To understand racial/ethnic minority adolescent females’ experiences with the vaginal ring. Methods We conducted in-depth interviews with a clinic-based sample of 32 young women aged 15–24 years who had used the vaginal ring. Results Qualitative analysis using grounded theory revealed that adolescents undergo a multi-stage process when trying the ring and adopting ring use. These stages include hearing about the ring, initial reactions, first experiences with insertion and removal, and first sexual experiences. Adolescents subsequently enter an assessment and adjustment stage in which they decide whether to adopt or discontinue ring use. Ultimately they share their experiences with friends. Conclusions The model developed provides a context within which providers may advise adolescents as they begin use of the ring. Some specific recommendations are offered. PMID:18565439

    On the basis of the studies of the embryogenesis of the vagina, the authors consider that malformations classically described as being partial aplasia should not be separated from the total absence of the vagina. The important feature is the association of a functioning or non functioning uterus with the absence of the vagina. They believe that it is incorrect to describe the pouch of menstrual retention associated with a functioning uterus as "haematocolpos" and that is not justified to describe the cup-shaped vestibular depression as "hemi-vagina". According to the authors, although vaginal aplasia with a functioning uterus forming a pouch of menstrual retention constitutes an absolute indication for surgery, surgery is not justified in cases of vaginal aplasia with a non functioning uterus. If Frank's method fails in these cases, the patient or the couple should be referred to a sexologist, as women with this anomaly retain a perfect femininity, although unable to conceive.

    Full Text Available A nine year–old wolf bitch was admitted to the surgical section of veterinary clinic teaching hospital in Mosul with abnormal mass occupying relatively the vulvar opening. According to the case history of owner, the bitch was suffered from varying degree of difficulty during parturition due to presence of this mass that showed during and after parturition. Appetite and all body health condition were normal. Clinical examination revealed presence of mass like tumor attached to the vaginal wall with numerous nodules or small growths originated also from wall of vulva near to large mass. The large growth was protruded completely through the vagina without any vaginal prolapse. After general anesthesia with ketamine and xylazine, the mass was surgically removed. Histopathological sections were revealed presence of fibrosarcoma which represented by arrangement of cells that have features of malignancy like darkly staining nuclei (hyperchromasia. The mass was diagnosed as a well-differentiated fibrosarcoma.

    Vaginitis is a commonly encountered complaint and one of the most frequent reasons for patient visit to obstetrician-gynaecologists. Three vaginal infections are frequent causes of a vaginal discharge: (1) bacterial vaginosis, (2) vulvovaginal candidiasis and (3) trichomonas vaginitis. Differences in the clinical presentation are helpful in diagnosis. Characteristic signs and symptoms for these three vaginal infections are distinct, but on many occasions, they are overlapping. The aim of the present study was to find the prevalence and correlation between the clinical spectrum and laboratory evidence of Trichomonas vaginalis infection by simple, reliable, confirmatory and specific method, i.e. microscopic examination of wet mount preparation and acridine stain of vaginal fluid. Irrespective of HIV status, a total of 156 women with vaginal discharge were studied for establishing diagnosis of genital tract infection. The cases of bacterial vaginosis and vulvovaginal candidiasis were excluded from the study. Vaginal speculum assisted high vaginal swabs were collected from women with discharge, during collection vagina was inspected for obvious signs. Of the 156 women with vaginal discharge, 19 (12.06 %) showed T. vaginalis infection. All the women belonged to active reproductive age group, i.e. 20-40 years. Itching dysuria, and offensive, malodorous, thin, yellowish vaginal discharge were the main and consistent complaints. Only in 2 (1.52%) cases, vaginal speculum examination revealed erythema and punctuate haemorrhage, the so-called "strawberry' vagina. The pH was recorded to be >4.5. Clinical differentiation of various forms of infectious vaginitis is unreliable. The prevalence of T. vaginalis infection at 12.06% was found among rural young women of reproductive age using simple and reliable screening wet mount microscopy.

    Querol, Amparo; Fernández-Espinar, M. Teresa; Belloch, Carmela

    The use of yeasts in biotechnology processes dates back to ancient days. Before 7000 BC, beer was produced in Sumeria. Wine was made in Assyria in 3500 BC, and ancient Rome had over 250 bakeries, which were making leavened bread by 100 BC. And milk has been made into Kefyr and Koumiss in Asia for many centuries (Demain, Phaff, & Kurtzman, 1999). However, the importance of yeast in the food and beverage industries was only realized about 1860, when their role in food manufacturing became evident.

    Full Text Available Background: The proper evaluation of the pelvic floor muscles (PFM is essential for choosing the correct treatment. Currently, there is no gold standard for the assessment of female PFM function. Objective: To determine the correlation between vaginal palpation, vaginal squeeze pressure, and electromyographic and ultrasonographic variables of the female PFM. Method: This cross-sectional study evaluated 80 women between 18 and 35 years of age who were nulliparous and had no pelvic floor dysfunction. PFM function was assessed based on digital palpation, vaginal squeeze pressure, electromyographic activity, bilateral diameter of the bulbocavernosus muscles and the amount of bladder neck movement during voluntary PFM contraction using transperineal bi-dimensional ultrasound. The Pearson correlation was used for statistical analysis (p<0.05. Results: There was a strong positive correlation between PFM function and PFM contraction pressure (0.90. In addition, there was a moderate positive correlation between these two variables and PFM electromyographic activity (0.59 and 0.63, respectively and movement of the bladder neck in relation to the pubic symphysis (0.51 and 0.60, respectively. Conclusions: This study showed that there was a correlation between vaginal palpation, vaginal squeeze pressure, and electromyographic and ultrasonographic variables of the PFM in nulliparous women. The strong correlation between digital palpation and PFM contraction pressure indicated that perineometry could easily be replaced by PFM digital palpation in the absence of equipment.

    Aims: To describe the magnetic resonance imaging (MRI) features of vaginal carcinoma and to suggest a role for MRI in its management. Materials and methods: Twenty-five patients with primary vaginal carcinoma treated at our institution between 1996 and 2005 were included in the study. The MRI examinations were reviewed and tumour dimensions, signal characteristics and involvement of pelvic structures were documented, as were sites of enlarged lymph nodes and metastases. Details of patient treatment and outcome were obtained from the clinical notes. Results: The median patient age was 54 years (range 31-86 years). Tumour maximum diameter ranged from 1.6-11.3 cm (mean 3.7 cm). Most tumours were of iso-intense signal to muscle on T1-weighted images and hyper-intense to muscle on T2-weighted images. Eighty-eight percent of patients had tumour extending beyond the vagina and 56% of patients had Figo stage III or above tumours. Sixteen patients were treated with radiotherapy (two with chemoradiotherapy), five with surgery and four with supportive care. Ten patients (40%) died of their disease during the study period. The MRI stage of the tumour correlated with survival. Conclusion: MRI identified over 95% of primary vaginal tumours in the present study, enabled radiological staging, which correlated with outcome, and provided information of use in treatment planning.

    Full Text Available Objective. To study the antimicrobial susceptibility of six vaginal probiotic lactobacilli. Methods. The disc diffusion method in Müeller Hinton, LAPTg and MRS agars by the NCCLS (National Committee for Clinical Laboratory Standards procedure was performed. Due to the absence of a Lactobacillus reference strains, the results were compared to those of Staphylococcus aureus ATCC29213. Minimal Inhibitory Concentration (MIC with 21 different antibiotics in LAPTg agar and broth was also determined. Results. LAPTg and MRS agars are suitable media to study antimicrobial susceptibility of lactobacilli. However, the NCCLS procedure needs to be standardized for this genus. The MICs have shown that all Lactobacillus strains grew at concentrations above 10 μg/mL of chloramphenicol, aztreonam, norfloxacin, ciprofloxacin, ceftazidime, ceftriaxone, streptomycin and kanamycin. Four lactobacilli were sensitive to 1 μg/mL vancomycin and all of them were resistant to 1000 μg/mL of metronidazole. Sensitivity to other antibiotics depended on each particular strain. Conclusions. The NCCLS method needs to be standardized in an appropriate medium to determine the antimicrobial susceptibility of Lactobacillus. Vaginal probiotic lactobacilli do not display uniform susceptibility to antibiotics. Resistance to high concentrations of metronidazole suggests that lactobacilli could be simultaneously used with a bacterial vaginosis treatment to restore the vaginal normal flora.

    To analyze deformation of the perineum during normal vaginal delivery in order to identify clinical steps that might be beneficial when executing manual perineal protection. The present prospective study at Charles University Hospital, Pilsen, Czech Republic, enrolled 10 primiparous women at term undergoing non-instrumental vaginal delivery assisted by the same obstetrician between September 2009 and September 2010. A modified hands-poised technique performed concurrently with stereophotogrammetry was used to analyze and quantify perineal deformation and strain at the final stage of delivery. The highest tissue strain (mean, 177%; 95% confidence interval [CI], 106.3-248.5) was in a transverse direction and occurred at the level of the fourchette (i.e. 1cm was transversely stretched and deformed to 2.77 cm during the final stage of vaginal delivery). This strain was more than 4 times higher than the maximum anteroposterior strain (mean, 43%; 95% CI, 28.6-57.4). On the basis of these stereophotogrammetry data, a technique of perineal protection executed by fingers of the posterior (right) hand can be proposed. Further experimental and clinical studies are needed to evaluate whether this technique might assist in reducing obstetric perineal trauma.

  5. Postmenopausal Vaginal Endometriotic Cyst: A Case Report

    2016-07-01

    Full Text Available A seventy-three-year-old patient%u2019s vaginal examination revealed a semi-mobile cystic structure visualised at the middle third portion of the posterior vaginal wall. The cyst was excised and the cyst wall was sent for pathological examination. The histopathological examination of the cyst with CD10 staining and tests for nuclear estrogen receptor positivity and nuclear progesteron receptor positivity revealed that the cyst wall contained endometrial stromal cells, endometrial surface epithelial cells, and hemosiderin-laden macrophages. Endometriosis externa was diagnosed based on the above findings. The case we report here, of an isolated vaginal endometriotic cyst, is unique because of its presentation in a postmenopausal woman without any history of infertility, any gynecologic surgery, or hormone replacement therapy. The reasonable explanation for this case might include certain mechanisms such as the self-sustaining existence of endometriotic cells that were implanted during the premenopausal period to the vagina and that maintain local estrogen production. No single hypothesis can explain the pathophysiology of endometriosis, given all of its various forms and presentations.
