    Full Text Available The purpose of this study is the determination of the occurrence and prevalence of clinical mastitis and lactation incidence risk on three dairy farms. A one year study on a total of 1031 black-white breed cows with a total of 1267 lactations was performed. Each dairy farm implemented a different technology of rearing and was of different herd size (farm A - tie-stalls, 162 cows; farm B - loose-housing system with open shed and deep bedding, 357 dairy cows; and farm C - loosehousing system with enclosed shed, 512 cows. Clinical mastitis in cows was detected by clinical examination of the udder and determination of abnormalities in the milk. To distinguish two consecutive cases of clinical mastitis within the same lactation a time period of nine days was used. Annual prevalence rate of clinical mastitis for the entire population of cows was 34.13% on cow level, and 30.07% on lactation level. There was a high prevalence rate of clinical mastitis in primiparous cows, 21.43%, 40.77% and 12.55%, on farms A, B and C, respectively. Lactation incident risk for cows on farm A was 25.00%, farm B 95.58% and farm C 21.49%. The prevalence of clinical mastitis and lactation incidence risk tended to increase with increasing parity. The annual lactation risk for the entire population of cows was 45.86%. All indicators for the determination of the occurrence of clinical mastitis in dairy farms, which were observed during the research, showed the greatest values on farm B. Most of the cows manifested one (68.24% or two (18.63% cases of clinical mastitis during lactation. There was a long period in lactation until the appearance of the first case of clinical mastitis (112.21 ± 92.04 days. Generally, clinical mastitis was registered during the whole period of the survey, with some fluctuations between different seasons. The method of GLM (General Linear Model, univariate procedure, was used to analyze associations between the incidence of clinical mastitis and farm management, parity of cows and season of the year. Pearson's coefficient of correlation was performed for analysis of interdependence on variables in the model. There was statistical significance (p<0,001 between the season and incidence of clinical mastitis. [Projekat Ministarstva nauke Republike Srbije, br. TR 31086

    Mastitis is a major source of economic loss in dairy herds. The objective of this research was to evaluate the association between genotypes within SLC11A1 and CXCR1 candidate genes and clinical mastitis in Holstein dairy cattle using the selective genotyping method. The data set contained clinical mastitis records of 3,823 Holstein cows from two Holstein dairy herds located in two different regions in Iran. Data included the number of cases of clinical mastitis per lactation. Selective genotyping was based on extreme values for clinical mastitis residuals (CMR) from mixed model analyses. Two extreme groups consisting of 135 cows were formed (as cases and controls), and genotyped for the two candidate genes, namely, SLC11A1 and CXCR1, using polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), respectively. Associations between single nucleotide polymorphism (SNP) genotypes with CMR and breeding values for milk and protein yield were carried out by applying logistic regression analyses, i.e. estimating the probability of the heterogeneous genotype in the dependency of values for CMR and breeding values (BVs). The sequencing results revealed a novel mutation in 1139 bp of exon 11 of the SLC11A1 gene and this SNP had a significant association with CMR (P G and these genotypes had significant relationships with CMR. Overall, the results showed that SLC11A1 and CXCR1 are valuable candidate genes for the improvement of mastitis resistance as well as production traits in dairy cattle populations. PMID:26126595

    Clinical mastitis in Spanish dairy herds has been studied. Since April 2005 up to December 2006, in 25 Spanish herds 1,054 cases registered were available. Aims were to determine mastitis incidence and factors of risk, to analyze whether yield production has been affected, and to quantify mastitis costs along 2006. The 25% lactations were infected at least once with average recurrence of 1.64. Descriptive analysis showed that 29% of cases occurred within the first month after calving. Primiparous showed higher mastitis frequency at early and late lactation while in multiparous cases number was progressively decreasing since the first month. Multiparous were statistically more liable to mastitis than primiparous. Mastitis did not show effect on yield production. Mastitis costs included treatment products and discarded milk. Individual daily production at each case onset was estimated by using monthly official milking records. An average mastitis case cost was 73.93, cheaper in primiparous than in multiparous because of lower milk production. Average discarded milk represented 74% of total cost per case. Mastitis costs were 117 per infected cow and lactation. Then, annual economic losses due to mastitis were 3,190 per average herd, showing the concern of producers on selecting resistant animals as well as the importance of the implementation of systematic recording for clinical mastitis in Spanish dairy farms. Additional key words: genetic selection, udder health. (Author) 28 refs.

    The objective of this study was to determine whether the occurrence of a previous case of pathogen-specific clinical mastitis (CM) protects Holstein dairy cows against a recurrent case. Pathogens studied were Escherichia coli, Staphylococcus aureus, Staphylococcus spp., Streptococcus spp., Klebsiella spp., and Trueperella pyogenes. A total of 40 864 lactations (17 265 primiparous and 23 599 multiparous) from 19 835 cows from 5 large, high milk producing New York State dairy herds were analysed. We estimated the effects of parity, calving diseases, milk yield, current season and number of CM cases in the previous lactation on the risk of a first CM case using generalised linear mixed models with a log link and Poisson error distribution. The aforementioned risk factors and the occurrence of previous cases of pathogen-specific CM within the current lactation were evaluated as risks for second and third cases of pathogen-specific CM. Cows with more CM cases in the previous lactation were at greater risk of pathogen-specific CM in the current lactation. Multiparous cows were at greater risk of a second CM case if they had suffered from a first CM case that was caused by the same pathogen as the second case. In contrast, a second CM case generally put cows at greater risk of a third case, irrespective of whether the third case was caused by the same or a different pathogen. Our results showed that a previous case of pathogen specific CM does not generally protect against a recurrent case. PMID:26568557

    coli infections were typically (truly) acute cases. Bacteriologically negative mastitis (20% of the cases) showed strong similarities with clinical coliform mastitis. Staphylococcus aureus cases (18% of the cases) occurred most frequently in late lactation or around drying-off. Prior isolation of Staph....... aureus and slight decreases in milk yield were two factors that interacted but both were strongly and positively related to clinical Staph. aureus. Staph. aureus mastitis typically had a subclinical debut, and increasing degrees and duration of inflammation decreased shedding of this pathogen...

    VetPath is an ongoing pan-European antimicrobial susceptibility monitoring programme collecting pathogens from diseased cattle, pigs and poultry not recently treated with antibiotics. Non-replicate milk samples were collected from cows with acute clinical mastitis in eight countries. Escherichia coli, Staphylococcus aureus and Streptococcus uberis were isolated by standardised methods. Antimicrobial susceptibility was determined in a central laboratory by CLSI broth microdilution methodology; results were interpreted using clinical breakpoints where available. Among E. coli (n=280), resistance to tetracycline (14.3%) and cefapirin (11.1%) were most common. Resistance to other β-lactam antibiotics was absent (ceftiofur) or very low (cefalexin, amoxicillin/clavulanic acid). The MIC90 of enrofloxacin and marbofloxacin was 0.03 and 0.06μg/mL, respectively, with 0.7% of strains displaying a deviating high MIC. Staphylococcus aureus (n=250) were susceptible to most antibiotics tested, although 36.0% were resistant to penicillin G. For other β-lactam antibiotics where a CLSI breakpoint was available, no resistance was detected. Tetracycline resistance was low (5.2%). Streptococcus uberis (n=282) were susceptible to all β-lactam antibiotics, although 29.8% were intermediately susceptible to penicillin G; 18.8% of strains were resistant to erythromycin and 28.7% to tetracycline. This European study shows that bacteria associated with acute clinical mastitis are susceptible to most antibiotics with the exception of penicillin G against S. aureus, and erythromycin and tetracycline against S. uberis. The results of this study should serve as a reference baseline. This work also highlights the urgent need to set additional clinical breakpoints for antibiotics frequently used to treat mastitis.

    Clinical mastitis in dairy cows has for many years been the subject of numerous epidemiological surveys to determine the main risk factors. In most cases this data has been analysed using a standard Poisson model without taking into consideration possible dependence between consecutive pathological events.

    Full Text Available Abstract A Bayesian procedure for analyzing longitudinal binary responses using a periodic cosine function was developed. It was assumed that, after adjustment for "seasonal" effects, the oscillation of the underlying latent variables for longitudinal binary responses was a stationary series. Based on this assumption, a single dimension sinusoidal analysis of longitudinal binary responses using the Gibbs sampling and Metropolis algorithms was implemented in a study of clinical mastitis records of Norwegian Red cows taken over five lactations.

    International Nuclear Information System (INIS)

    To determine the clinical characteristic, clinical presentations and radiological features of diopathic granulomatous mastitis, and the best treatment approaches of this clinical entity. Between 1996 and 2003 the files and histopathology reports of 25 patients with granulomatous mastitis at King Abdul-Aziz University Hospital Jeddah, Kindom of Saudi Arabia were reviewed. The data were analyzed and a Medline search was carried out from 1970 to 2003 to review relevant cases. The age of patients ranged from 24-66 years and the mean age was 36.6+-9.43 years. All patients were females. The most common clinical presentation was palpable tender mass. The most common mammographic finding was ill-defined mass. However, mixed hypo- and hyper-echogenic lesions with tubular connections were the common ultrasonic findings. Treatment approaches were conservative or surgical excision or steroid. Conservative treatment associated with the higher rate of complications, while treatment with steroid showed complete remission of disease. Idiopathic granulomatous mastitis is a rare, benign breast disease that is usually underestimated or misdiagnosed. The clinical and radiological features resemble those of infectious mastitis or breast carcinoma. Early recognition and initiation of steroid treatment will result in complete remission of the disease and prevent complications. (author)

The cow showed clinical signs of mastitis in both front mammary quarters and marked reduction on milk production. Following the diagnosis the animal was accompanied for 11 months. Milk samples collected at days l, 7, 30, 39, 49, 65, 326 and 331 were cultured. The last two exams were conducted at 7 and 12 days after calving. The P. zopfii strains were resistant in vitro to: ampicillin, kanamycin, cephalothin, enrofloxacin, streptomycin, gentamycin, neomycin, oxacillin, penicillin G, sulfonamides and trimethoprim/sulfamethoxazole. The strains showed sensitivity in vitro to a natural extract made of citrous seed, commercially available. The smallest concentration that completely inhibited the growth of the organisms was 1:500. The infected glands were treated intrammamary, with an extract preparation of a 1:200 dilution in 0.85%(p/v NaCl containing 1:30,000 thimerosal as preservative. Doses of 20ml were applied daily, during seven days. After this period, P. zopfii was still isolated from milk samples, although in smaller numbers. The treatment was resumed for a period of 15 days. At day 39 after diagnosis the infected quarters were cultured negative and microbiological exams carried out from day 39 onward resulted negative. The milk production returned to levels as before infection. Naturally infected milk samples were kept frozen (-20C and viable P. zopfii were recovered until 38 days under this condition.

  14. Clinical Mastitis and Combined Defensin Polymorphism in Dairy Cattle

    Full Text Available Identification of marker sequences related to immunity towards mastitis may be instrumental in improving resistance against this trait and as a result may reduce the costs related to the prevention and treatment of the disease. The ideal candidate genetic markers for immunity towards mastitis are the genes encoding bovine defensins which belong to the wide and varied group of peptide antibiotics. A lot of antimicrobial peptides identified in cattle have been classified as β-defensins. Defensins are particularly active against gram-positive bacteria and fungi but at higher concentrations they are also, capable of destroying gram-negative bacteria, mycobacteria, enveloped viruses and some protozoons. The aim of this study was to search for associations between the occurrence of clinical mastitis and Combined Defensin Genotypes (CDG and to investigate the possibility of using defensin gene polymorphisms in marker-assisted selection for immunity towards mastitis in dairy cows. This study included such indicators as the number of clinical cases of mastitis acuta and chronica, number of affected udder quarters and duration of the condition in 1,025 cows (Polish Holstein-Friesian breed kept on a farm located in the North-Western region of Poland. The cows were of different ages and in different lactations parities (from 1st to 6th. An analysis of associations between selected CDGs and susceptibility/immunity towards mastitis has showed statistically significant relations with regard to all the indicators under study and CDGs. Moreover, some genotypes have been found to have different effects on chronic and acute infections.

  15. The clinical and mammographic features of plasma cell mastitis

    International Nuclear Information System (INIS)

    Objective: To investigate the clinical and mammographic features of plasma cell mastitis. Methods: Twenty-five patients (28 lesions) with histologically confirmed plasma cell mastitis, aged from 26 to 70 years (mean age 41 years), were examined with X-ray mammography. The clinical manifestations and imaging features were retrospectively reviewed. Results: No case was in lactation. The painful irregular masses, ranged from 1.3 to 8cm in size, were found in 22 patients, while 3 patients with acute episode. Recurrent episodes of breast masses were noted in 4 patients. Based on the mammographic appearances, the plasma cell mastitis were classified as the following four types: inflammation-like type (2/28), ductal ectasia type (3/28), focal infiltration type (10/28) and nodular type (13/28). The valuable radiographic signs: (1) An asymmetrically increased density along the lactiferous duct with a flame-like appearance, inhomogeneous low density tubular structures and scattered stick-shape calcifications. (2) Architectural distortion and oil cysts formation in adjacent area, (3) Subareolar ductal ectasia. Conclusions: The clinical and mammographic characteristics of plasma cell mastitis are critical to avoiding unnecessary surgery. Histopathological result is needed for the diagnosis in patients highly suspected of malignancy. (authors)

    Clinical mastitis results in considerable economic losses for dairy producers and is most commonly diagnosed in early lactation. The objective of this research was to estimate the economic impact of clinical mastitis occurring during the first 30 days of lactation for a representative US dairy. A deterministic partial budget model was created to estimate direct and indirect costs per case of clinical mastitis occurring during the first 30 days of lactation. Model inputs were selected from the available literature, or when none were available, from herd data. The average case of clinical mastitis resulted in a total economic cost of $444, including $128 in direct costs and $316 in indirect costs. Direct costs included diagnostics ($10), therapeutics ($36), non-saleable milk ($25), veterinary service ($4), labor ($21), and death loss ($32). Indirect costs included future milk production loss ($125), premature culling and replacement loss ($182), and future reproductive loss ($9). Accurate decision making regarding mastitis control relies on understanding the economic impacts of clinical mastitis, especially the longer term indirect costs that represent 71% of the total cost per case of mastitis. Future milk production loss represents 28% of total cost, and future culling and replacement loss represents 41% of the total cost of a case of clinical mastitis. In contrast to older estimates, these values represent the current dairy economic climate, including milk price ($0.461/kg), feed price ($0.279/kg DM (dry matter)), and replacement costs ($2,094/head), along with the latest published estimates on the production and culling effects of clinical mastitis. This economic model is designed to be customized for specific dairy producers and their herd characteristics to better aid them in developing mastitis control strategies. PMID:26596651

    Full Text Available BACKGROUND: Granulomatous lobular mastitis (GLM is an inflammatory disease of the breast, which can mimic breast cancer in clinical and radiological findings. We conducted the present study in order to determine the diagnostic and other important aspects of this disease. METHODS: In this study, we reviewed the records of 38 patients with granulomatous lobular mastitis in order to describe the clinical, imaging, laboratory, pathologic, and treatment aspects of this disease. RESULTS: All of the patients’ ages were in the range of 22-62 years (mean age: 42 years. All of them had children, history of oral contraceptive pill (OCP usage, antibiotic therapy and mammoplasty. In physical examination, dimpling, edema, inflammation, ulcer, abscess, and firm mass were detected. Size of masses was in the range of 2 × 2 to 8 × 6 cm and their location, in most cases, was in the superior lateral quadrant or central region. In Ultrasonography, a hypoechoic fibroglandular mass and collection, and in pathologic findings, granulomatous reaction was reported. These patients were treated by antibiotics, corticosteroids, and surgery. CONCLUSIONS: GLM is a chronic inflammatory lesion of the breast which can mimic breast cancer. A history of child bearing, lactation, and OCP drug usage have suspicious roles in the formation of GLM. The most common clinical sign in these patients is a painful mass in the breast. We uncovered that clinical and radiological findings are not specific and sufficient for diagnosis of GLM. Therefore, for better diagnosis of this disease, usage of core, incisional, or excisional biopsy are recommended.

    Full Text Available Problem statement: Granulomatous Lobular Mastitis (GLM or autoimmune mastitis is a rare and benign disease which, except one case reported in an old man, is usually seen during pregnancy or lactation period. This disease was described for the first time by Kessler. Approach: Our case is a 34 year-old woman who has a child with a history of using OCP that primary complaint was swelling, heat and erythema in the right breast. She was diagnosed with mastitis and treated with antibiotics for one month, later on she had experienced stiffness in the breast and a mass was also palpable. The patient was performed surgical drainage and treated with wide spectrum antibiotics being diagnosed with abscess. After one month, a solid mass was palpable so, mammography was performed and the mass was surgically resected with a suspicion of tumor. Results: The pathology report revealed granulomatous mastitis with non caseified granuloma. For Anti-TB treatment was started as medication regime and after 40 days fistula with frequent secretions appeared. Antituberculosis medications stopped and other conditions resulting in none caseified granuloma. In microscopic view granulomatous mastitis along with abscess was reported. Corticosteroids were started and the mass became smaller gradually, the fistula also closed and secretions dried out. Conclusion: Granulomatous Lobular Mastitis is a benign inflammatory breast disease. Cause of disease is still unknown, but some factors have been suggested such as local autoimmune, reaction to the delivery, previous use of contraceptives and infectious causes. The best treatment proposed is corticosteroid therapy in which the mass dwindle and the fistula is closed and secretions dried. The case is now under treatment with corticosteroids and all her symptoms have improved.

    Full Text Available Mastitis is an infectious or non-infectious breast disease associated with breast inflammation. It is observed most frequently during milk stasis (engorgement and lactation period (puerperal with superimposed infection. Most mastitides heal with simple self-help measures, however, sometimes antibiotherapy and abscess drainage may be required. Other than lactating period, mastitides are encountered in the presence of recurrent infections and abscess. Although various factors, such as smoking, diabetes, rheumatoid arthritis can at times be the root causes of mastitis, they are frequently observed in granulomatous mastitides. Treatment approaches not involving biopsy are disadvantageous and harmful in such cases which can be confused with breast cancer. Ultrasound-guided abscess drainage in patients with breast abscess and irrigation of the pouch with saline are the preferred treatment approach today.

    The objective of this study was to estimate the milk production losses associated with clinical mastitis using mixed linear models and correlation structures that have not been available previously. Data used included computer-recorded daily milk yields and detailed and accurate recordings of clinical mastitis cases. Two commercial Holstein dairy farms in New York State participated in the study, one with 650 lactating cows and another that began the study with 830 lactating cows and increased to 1120 cows by the end of the study. Cows on both farms were housed in free stall barns and milked 3 times daily in milking parlors. Electrical conductivity was used as a diagnostic aid for clinical mastitis on both farms. Date of clinical onset was recorded for every episode of clinical mastitis as well as for 8 other diseases defined using standardized case definitions (dystocia, milk fever, retained placenta, metritis, ketosis, displaced abomasum, lameness, and cystic ovarian disease) during the study period of October 1, 1999 to July 31, 2001. The mixed linear model for explaining variation in the outcome variable daily milk yield relative to non-mastitic herdmates found the terms for all 9 diseases studied, including clinical mastitis, significant. The model with an autoregressive correlation structure was preferred based on -2 * log likelihood, Akaike's information criterion, and Bayesian information criterion as well as savings in degrees of freedom. Separate analyses were run for first lactation cows and for second-plus lactation cows because their lactation curves were shaped differently. Adjusting for the effects of the other 8 diseases, milk production loss from clinical mastitis during the whole lactation was estimated as approximately 598 kg for second-plus lactation cows. However, cows that contracted mastitis had a daily production advantage of 2.6 kg over their herdmates until they contracted the disease. When compared with this potentially higher milk production, the total loss from clinical mastitis was estimated as 1181 kg. PMID:15328219

    Full Text Available A cross sectional study was conducted during October and November 2006 on 69 smallholder dairy farms with lactating cows in Mvomero and Njombe districts Tanzania, to determine the prevalence of mastitis and to assess the milk quality on the study farms. Clinical mastitis was investigated using clinical changes of udder and milk at animal level. Cow-side California Mastitis Test (CMT and microbiological cultures were used to assess subclinical mastitis at quarter level. Milk quality was determined on bulk milk samples at herd level using alcohol and acidity tests, butter fat content, total solids, ash content as well as Delvotest® for antimicrobial residues. Overall prevalence of clinical mastitis at herd level in both districts was 21.7 % (n = 69. Based on CMT, prevalence of subclinical mastitis at animal level was 51.6 % (n = 91. Prevalence of bacterial isolates at animal level was 35.2 % (n = 91 while for fungal it was 16.7 % (n = 90. Based on CMT results, prevalence of subclinical mastitis at quarter level was 30 % (n = 353, while for bacteria and fungi it was 16 % and 6 % respectively. Contamination of milk with antimicrobial residues was 4.5 % (n =67. The milk quality parameters for most of the milk samples were within acceptable levels. Findings in this study have demonstrated high prevalence of subclinical mastitis that may contribute to low productivity of dairy cattle in both districts. About 20 % of CMT subclinical cases had no involvement of microbial pathogens that suggested the need for minimal interventions with antimicrobial agents. These findings call for use of udder disinfectants and improved milking hygiene as intervention strategies to control mastitis on the smallholder dairy farms in Tanzania.

    This research investigated somatic cell count (SCC) records during lactation, with the purpose of identifying distribution characteristics (mean and measures of variation) that were most closely associated with clinical mastitis. Three separate data sets were used, one containing quarter SCC (n = 1444) and two containing cow SCC (n = 933 and 11,825). Clinical mastitis was defined as a binary outcome, present or absent, for each lactation, and SCC were log (base 10) transformed. A generalized ...

    To decide about investments in preventive measures improving udder health it is important that the farmer knows the monetary loss due to mastitis on his specific farm. The Saxon dairy herd improvement association (Schsischer LandeskontrolIverband e.V., LKV) is developing a computer program called "Daten- und Informationsplattform Tier (DIT)"which determines - among other analyses - the milk loss caused by mastitis for a specific herd based on individual cow's mastitis and daily milk yield data. The present article introduces the linear mixed model which is taken as a basis for calculating the reduction in performance through clinical mastitis. The short and long term decrease in daily milk yield is described by expanding the lactation curve model of Ali and Schaeffer (1987). For falculating the short term drop, the model includes the laps of time in days since the mastitis incident as secon-ddegree polynomial. The coefficients are estimaged specifically for the first respectively every following case of mastitis (class of episode). Classes of episode are also considered calculating the long term decrease by estimating lactation curves without mastitis as well as corresponding to the classes of episode. By integrating the statistic software R (R Development Core Team, 2012) into the processes of the DIT the estimation of the farm specific model parameters is largely automated on the servers of the LKV.Thereby, milk yield can be estimated for every day in milk according to episode number and laps of time since the incident or with no mastitis incident respectively for a particular period of time in a specific dairy herd. The loss resulting from reduced performance due to clinical mastitis is specified by adding up the differences and can serve as a valuable basis for management decisions. PMID:23901581

    Full Text Available Aim: To evaluate blood antioxidant profile and lipid peroxides in dairy cows with clinical mastitis. Materials and Methods: Twelve cases of clinical mastitis in cross-bred cows were selected based on physical examination of udder and milk, California Mastitis Test (CMT, Somatic Cell Count (SCC and confirmation by bacteriological examination of milk and requisite biochemical tests. Twelve lactating cows showing negative CMT reaction and SCC <2x105 cells/ml were considered as healthy control. Antioxidant parameters measured in blood were superoxide dismutase (SOD, catalase activities and reduced glutathione (GSH concentration. Erythrocytic lipid peroxidation (LPO was measured in terms of malondialdehyde (MDA production. Results: Significant (P<0.05 decrease in blood SOD and catalase activities, GSH concentration and an increase in erythrocytic lipid peroxides was observed in cows with clinical mastitis. Conclusion: It is concluded that there is a compromise in antioxidant defense of the body in dairy cows with clinical mastitis resulting in oxidative damage, therefore, necessitate the use of antioxidants and other protective compounds along with conventional therapy for mastitis control.

    2016-04-01

    In 2010, a routine genetic evaluation on occurrence of clinical mastitis in three main dairy cattle breeds - Montbéliarde (MO), Normande (NO) and Holstein (HO) - was implemented in France. Records were clinical mastitis events reported by farmers to milk recording technicians and the analyzed trait was the binary variable describing the occurrence of a mastitis case within the first 150 days of the first three lactations. Genetic parameters of clinical mastitis were estimated for the three breeds. Low heritability estimates were found: between 2% and 4% depending on the breed. Despite its low heritability, the trait exhibits genetic variation so efficient genetic improvement is possible. Genetic correlations with other traits were estimated, showing large correlations (often>0.50, in absolute value) between clinical mastitis and somatic cell score (SCS), longevity and some udder traits. Correlation with milk yield was moderate and unfavorable (ρ=0.26 to 0.30). High milking speed was genetically associated with less mastitis in MO (ρ=-0.14) but with more mastitis in HO (ρ=0.18). A two-step approach was implemented for routine evaluation: first, a univariate evaluation based on a linear animal model with permanent environment effect led to pre-adjusted records (defined as records corrected for all non-genetic effects) and associated weights. These data were then combined with similar pre-adjusted records for others traits in a multiple trait BLUP animal model. The combined breeding values for clinical mastitis obtained are the official (published) ones. Mastitis estimated breeding values (EBV) were then combined with SCSs EBV into an udder health index, which receives a weight of 14.5% to 18.5% in the French total merit index (ISU) of the three breeds. Interbull genetic correlations for mastitis occurrence were very high (ρ=0.94) with Nordic countries, where much stricter recording systems exist reflecting a satisfactory quality of phenotypes as reported by the farmers. They were lower (around 0.80) with countries supplying SCS as a proxy for the international evaluation on clinical mastitis. PMID:26592099

    Multilocus sequence typing was successfully completed on 494 isolates of Streptococcus uberis from clinical mastitis cases in a study of 52 commercial dairy herds over a 12-month period. In total, 195 sequence types (STs) were identified. S. uberis mastitis cases that occurred in different cows within the same herd and were attributed to a common ST were classified as potential transmission events (PTEs). Clinical cases attributed to 35 of the 195 STs identified in this study were classified PTE. PTEs were identified in 63% of the herds. PTE-associated cases, which include the first recorded occurrence of that ST in that herd (index case) and all persistent infections with that PTE ST, represented 40% of all the clinical mastitis cases and occurred in 63% of the herds. PTE-associated cases accounted for >50% of all S. uberis clinical mastitis cases in 33% of the herds. Nine STs (ST-5, -6, -20, -22, -24, -35, -233, -361, and -512), eight of which were grouped within a clonal complex (sharing at least four alleles), were statistically overrepresented (OVR STs). The findings indicate that 38% of all clinical mastitis cases and 63% of the PTEs attributed to S. uberis in dairy herds may be caused by the nine most prevalent strains. The findings suggest that a small subset of STs is disproportionally important in the epidemiology of S. uberis mastitis in the United Kingdom, with cow-to-cow transmission of S. uberis potentially occurring in the majority of herds in the United Kingdom, and may be the most important route of infection in many herds.

    Full Text Available Objective: To determine the prevalence of mastitis-causing bacteria in the dry period and its antibiotic sensitivity. Methods: In this study, 852 dry cows were examined. A total of 30 cows with clinical mastitis symptoms were detected and their milk samples were collected. In order to purify the bacteria, brain heart infusion and blood agar media were applied and single colonies were used for Gram staining, oxidase and catalase testing, cultivating in O-F medium to determine the genus and species of bacteria. Then, antimicrobial susceptibility was tested by the agar disk diffusion method. Results: The prevalence of isolated bacteria was 2.46%, in which coagulase positive Staphylococcus, coagulase negative Staphylococcus, Streptococcus dysgalactiae, Streptococcus faecalis, Escherichia coli, Pseudomonas, Bacillus and yeast were (9/99%, (6/66%, (13/32%, (3/33%, (6/66%, (13/32%, (9/99% and (6/66%, respectively. After tests of antibiotic susceptibility, the most and the least sensitivity were reported to enrofloxacin and ampicillin respectively. Conclusions: This study indicated that Streptococcus dysgalactiae is the most commonly isolated bacteria with the greatest sensitivity to enrofloxacin and tetracycline which can be used to treat mastitis in the dry period in Tabriz.

    Full Text Available Abstract Background Mastitis is a common problem for breastfeeding women. Researchers have called for an investigation into the possible role of maternal nasal carriage of S. aureus in the causation of mastitis in breastfeeding women. Methods The aim of the study was to investigate the role of maternal S. aureus nasal carriage in mastitis. Other factors such as infant nasal S. aureus carriage, nipple damage, maternal fatigue and oversupply of milk were also investigated. A case-control design was used. Women with mastitis (cases, n = 100 were recruited from two maternity hospitals in Melbourne, Australia (emergency departments, breastfeeding clinics and postnatal wards. Breastfeeding women without mastitis (controls, n = 99 were recruited from maternal and child health (community centres and the rooms of a private obstetrician. Women completed a questionnaire and nasal specimens were collected from mother and baby and placed in charcoal transport medium. Women also collected a small sample of milk in a sterile jar. Results There was no difference between nasal carriage of S. aureus in breastfeeding women with mastitis (42/98, 43% and control women (45/98, 46%. However, significantly more infants of mothers with mastitis were nasal carriers of S. aureus (72/88, 82% than controls (52/93, 56%. The association was strong (adjusted OR 3.23, 95%CI 1.30, 8.27 after adjustment for the following confounding factors: income, private health insurance, difficulty with breastfeeding, nipple damage and tight bra. There was also a strong association between nipple damage and mastitis (adjusted OR 9.34, 95%CI 2.99, 29.20. Conclusion We found no association between maternal nasal carriage of S. aureus and mastitis, but nasal carriage in the infant was associated with breast infections. As in other studies of mastitis, we found a strong association between nipple damage and mastitis. Prevention of nipple damage is likely to reduce the incidence of infectious mastitis. Mothers need good advice about optimal attachment of the baby to the breast and access to skilled help in the early postpartum days and weeks.

    Full Text Available A cross sectional study was conducted on 322 local (n = 57 and crossbred (n = 265 lactating hand milked small holder cows in and around Gondar. The objective of the study was to determine prevalence of clinical and sub clinical mastitis and the associated risk factors by clinical examination and using california mastitis test. Bacterial culture was also conducted to determine the casual agents of mastitis. The prevalence of clinical and sub clinical mastitis in the study area was 0.93 and 31.67%, respectively with an overall prevalence of 32.6%. Out of 1288 quarters examined 164 were infected while 39 were blind. The number of clinically and sub clinically infected quarters were 7 and 157, respectively. Several pyogenic bacteria have been isolated from cases of sub clinical mastitis during the study period. The major bacteria isolated in this study were Staphylococcus aureus, Streptococcus agalactiae and Streptococcus dysgalactiae with a prevalence of 16.5, 15.9 and 14.0%, respectively. Among the risk factors considered, breed, age, parity and stage of lactation have been shown statistically significant (p<0.05 difference in the prevalence of mastitis. Sub clinical mastitis in both breeds has been reported to be higher than clinical mastitis. The odds of occurrence of mastitis were two times more likely in crossbreds compared to local zebu. The present study disclosed that high prevalence of sub clinical mastitis and the occurrence Staphylococcus and Streptococcus spp. as dominant bacterial species from mastitic milk of the study area. All the risk factors considered were significant effect on the prevalence of mastitis. Appropriate control and prevention methods should be applied to reduce the prevalence and effect of mastitis in dairy cows.

    Full Text Available Mastitis is probably the most common and costly disease in modern dairy cow husbandry. The aim of the present paper was to report the results concerning udder health after implementation of a specific strategy using both field and laboratory methods. During the period June 2010-December 2011 a total of 674 dairy cows from four dairy farms were included in the investigation. Clinical mastitis was diagnosed by detection of signs of inflammation in the udder, while subclinical mastitis was diagnosed at the animal level by an increased Somatic Cell Count (SCC using laboratory tests, and subsequently confirmed at quarter level by California Mastitis Test (CMT.Microbiological analysis of the milk samples was carried out by standard procedures using Gram staining, biochemical tests and automated identification system.The distribution of somatic cell counts on cow level (n=674 was:305 (45.3% with SCC less than 100,000SCC/mL, 236 (35.0% 100,001 - 350,000 SCC/mL, and 133 (18.7% with more than 350,000SCC/mL. From a total of 1684 quarters tested by CMT, 644 quarters (38.2% were positive and 1040 quarters (61.8% were negative. In 60 out of 101 quarters that had a positive CMT result and no current treatment and that were sampled for bacteriology, bacteria could be isolated. Main bacteria identified, were coagulase - negative staphylococci (40.0%, Streptococcus agalactiae was present in 25.0%, Escherichia coli in 16.6%, Proteus spp. in 11.7% and Staphylococcus aureus in 6.7% of the bacteriological positive samples. After introducing specific mastitis-control measures, focusing on milking hygiene, dry-off treatment, and antibiotic treatment of both clinical and sub-clinical mastitis cases, the prevalence of subclinical mastitis was reduced from 38.2to 10.8%, while the incidence of clinical mastitis decreased from 21.0% to 4.9%.In conclusion, the implementation of a standard mastitis control plan based on a regular assessment of the somatic cell count can reduce the prevalence of clinical and sub-clinical mastitis in dairy herds.

    Information related to mastitis risk factors is useful for the design and implementation of clinical mastitis (CM) control programs. The first objective of our study was to model the risk of CM under Brazilian conditions, using cow-specific risk factors. Our second objective was to explore which risk factors were associated with the occurrence of the most common pathogens involved in Brazilian CM infections. The analyses were based on 65 months of data from 9,789 dairy cows and 12,464 CM cases. Cow-specific risk factors that could easily be measured in standard Brazilian dairy farms were used in the statistical analyses, which included logistic regression and multinomial logistic regression. The first month of lactation, high somatic cell count, rainy season and history of clinical mastitis cases were factors associated with CM for both primiparous and multiparous cows. In addition, parity and breed were also associated risk factors for multiparous cows. Of all CM cases, 54% showed positive bacteriological culturing results from which 57% were classified as environmental pathogens, with a large percentage of coliforms (35%). Coagulase-negative Staphylococcus (16%), Streptococcus uberis (9%), Streptococcus agalactiae (7%) and other Streptococci (9%) were also common pathogens. Among the pathogens analyzed, the association of cow-specific risk factors, such as Zebu breed (OR=5.84, 95%CI 3.77-10.77) and accumulated history of SCC (1.76, 95%CI 1.37-2.27), was different for CM caused by Coagulase-negative Staphylococcus and S. agalactiae in comparison to CM caused by coliforms. Our results suggest that CM control programs in Brazil should specially consider the recent history of clinical mastitis cases and the beginning of the lactations, mainly during the rainy season as important risk factor for mastitis.

    Full Text Available Inflammation of the mammary gland, which is also known as mastitis, occupies a prominent place among the diseases that affect dairy cattle, having a great economic importance in the dairy sector. Mastitis may have different origins, however, infectious mastitis is the most frequent and represents a risk to public health due to the propagation of microorganisms through milk. Staphylococcus spp. are considered the microorganisms that cause the greatest losses in milk production, being that Staphylococcus aureus is the pathogen of major importance because they present high resistence to antimicrobials. Empirical treatment, without prior identification of the pathogens and their resistance profile, may contribute to the emergence of multidrug-resistant strains and risk the efficiency of the antimicrobial. In that scenery, the study aimed to evaluate the resistance profile of Staphylococcus spp. against some antimicrobials used in the treatment of cows with clinical mastitis. The study was conducted on a property in the state of São Paulo from January 2011 to June 2012. We evaluated 29 lactating cows that present clinical mastitis in, at least, one mammary quarter. The diagnosis of clinical mastitis was performed by evaluating the clinical signs and also by Tamis test. Samples of milk from mammary quarters were collected aseptically in sterile tubes for microbiological evaluation. Microorganisms were isolated on sheep blood agar 5% and Sabouraud agar with chloramphenicol. The sensitivity profile of Staphylococcus spp. to the antibiotics ampicillin, cephalexin, ceftiofur, cefaclor, gentamicin, kanamycin, neomycin, penicillin G and oxacillin, was tested by disk diffusion test on Mueller-Hinton agar. From a total of 106 samples of milk analyzed, 64 (60.38% presented microbiological growth, being observed isolation of Streptococcus spp. 29 (34.52%, Staphylococcus spp. 28 (33.33%, Corynebacterium spp. 17 (20.24%, filamentous fungi 4 (4.76%, yeast 4 (4.76% and Gram-negative bacilli 2 (2.38%. From total of Staphylococcus spp. isolates, 67.86% were sensitive to all antibiotics tested. Resistance to penicillin G was evidenced in 25% of the strains, to ampicillin in 28.57% and 10.71% to neomycin. It was also observed that 3.57% of strains tested were resistant to all antibiotics. The isolation of multidrug-resistant strains presents risks to the health of the animal and the consumer because they can be transmitted through milk products. The identification of pathogens and the performance of antimicrobial susceptibility profile are essential for monitoring and control of multidrug-resistant strains.

    Full Text Available A total of 51 cases of bovine clinical mastitis in Sulaimani district were investigated for their bacteriological causative agents; 76 milk samples were cultured on primary and selective media and the isolated bacteria were tested for their susceptibility to antimicrobial agents used in commercial intramammary infusion products. Eighty two bacterial isolates were obtained and further identified using biochemical tests. Escherichia coli was the most common bacteria followed by Staphylococcus aureus, Streptococcus agalactia and coagulase–negative staphylococci. Two other bacterial species (Pseudomonas aeruginosa and Streptococcucs uberis were also isolated but in a lower proportion. Antibacterial susceptibility testing showed that the use of florfenicol, cephalexin and gentamicin may be useful for the treatment of clinical mastitis cases in cows.

    Full Text Available Aim: The present study was planned to determine the in vitro antibiotic susceptibility of coagulase-negative Staphylococci (CNS strains isolated from clinical and subclinical cases of mastitis in dairy cows. Antibiotic sensitivity profile will be helpful to recommend early therapy at the field level prior to availability of CST results. Materials and Methods: The milk samples from cases of clinical mastitis received in Mastitis Laboratory, Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana and those of subclinical mastitis collected during routine screening of state dairy farms, were subjected to microbial culture. Identification of CNS organisms was done by standard biochemical tests. Antibiotic sensitivity testing, based on 30 antibiotics belonging to 12 groups, was done on 58 randomly selected CNS isolates (clinical isolates: 41, subclinical isolates: 17. Results: Isolates were highly susceptible to chloramphenicol (98.3%, gentamicin (93.1%, streptomycin (91.4%, linezolid (91.4%, ceftixozime (87.9%, cloxacillin (86.2%, clotrimazole (86.2%, bacitracin (86.2%, enrofloxacin (84.5% and ceftrioxone + tazobactum (70.7%, while resistance was observed against amoxicillin (77.6%, penicillin (75.9%, ampicillin (74.1% and cefoperazone (51.7%. Overall, isolates from clinical cases of mastitis had a higher resistance than subclinical isolates. Conclusion: CNS isolates were susceptible to chloramphenicol, gentamicin and streptomycin, while higher resistance was recorded against routinely used penicillin group.

    A total of 90 cows from three commercial farms were used to evaluate the relationship between subclinical mastitis and clinical mastitis and thermal nociceptive threshold. Milk strips from all udder quarters were tested for clinical mastitis with visual inspection of milk and udder alterations and for subclinical mastitis using California Mastitis Test. Milk yield was recorded, milk was sampled and further analyzed for somatic cells count (SCC). Cows were considered healthy when SCC200 000 cells/ml and no visual alterations in milk and/or udder, with moderate subclinical mastitis when SCC>500 000 cells/ml and no visual alterations in milk and/or udder and with clinical mastitis when visual alterations in milk and/or udder were detected. Nociceptive threshold was evaluated with the thermal threshold meter apparatus applied to the rear legs. Thermal threshold (TT) decreased when we compared healthy cows with cows presenting clinical mastitis and tended to decrease when we compare healthy cows with those with moderate subclinical mastitis. TT was lower at the ipsilateral rear leg compared with the contralateral leg to the infected mammary gland. TT linearly decreases as log10SCC increased and it showed sharp decrease as log10SCC exceed the value of 6.4. Increase in one unit of log10SCC increased the odds of low thermal threshold (lower than 55.8C). Subclinical mastitis might be a welfare issue as it tended to decrease nociceptive thermal threshold.

  10. Immunoprophylaxis of bovine mastitis

    2003-01-01

    Full Text Available Mastitis poses a major economic and health problem in herds of dairy cows. The many years of taking different approaches to treating mastitis have not resulted in an adequate solution, so that the problem of mastitis is still present and acute. The treatment of mastitis using antibiotics yields satisfactory results, but it implies substantial costs for treatment and losses in rejecting milk. Due to the above reasons, a new area of scientific research offers possibilities for finding new solutions to the ever present problem of mastitis - immunoprophylaxis. Vaccines against mastitis available at this time are still not sufficiently effective in general practice, and they are at the level of experimental vaccines. All barn vaccines which have been worked on so far have been significantly experimentally successful. The success is in a significant increase in the antibody titer in serum (but not in milk, as well as in reducing the incidence of clinical and subclinical mastitis cases among experimental and control animals. Nevertheless, it is still believed that immunoprophylaxis, as a method for preventing inflammation of the udder and the occurrence of mastitis, is still an insufficiently investigated field of scientific research. Many scientists are engaged on the problem of finding a vaccine against mastitis, but the coplexity of the mammary gland and the specific permeability of the blood-milk barrier do not permit these efforts to be as successful as they might be if this were not the case.

    Full Text Available Mastitis in dairy cows is an economically important disease because it makes up 38% of all diseases that occur in intensive cattle breeding. Mastitis affects milk production, either temporarily or permanently, depending on the course of infection and type of pathogen agent. Regular and timely therapy of mastitis based on the application antimicrobials, apart from prophylaxis, is very important for good health of breeding stock. This paper presents the case of repeated mastitis in a cow, Holstein-Friesian breed, 5 years old, which did not respond to antibiotic therapy. Milk samples from each separate quarter of the udder were collected under aseptic conditions and sent to the laboratory for further bacteriological tests, for isolation and identification of pathogens, as well as to test pathogen resistance to some antibiotics. On the basis of bacteriological examinations, there was confirmed the presence of Streptococcus dysgalactiae, which showed sensitivity to ampicillin, cloxacillin and augmentin, intermediate resistance to tetracycline and resistance to kotrimeksazol.(cotrimoxazole-proveriti [Projekat Ministarstva nauke Republike Srbije, br.

    Due to the increasing use of automated milking systems, automated detection of clinical mastitis is becoming more important. Various in- or on-line diagnostic tests are in use, but generally suffer from false mastitis alerts. In this study, we explored a new diagnostic approach based on measurement of protease activity using fluorogenic protease substrates, which can be performed on site, at high speed, and at low costs. Samples from cows with clinical mastitis submitted for bacteriological culture at the University Farm Animal Practice were collected during several months and kept at -20°C until protease activity measurement. A reference set of milk samples from clinically healthy cows were collected on 9 different farms and were tested for protease activity directly and after freezing at -20°C to allow for comparison with the samples from clinical cases. The protease activity in mastitic milk samples was significantly higher than in samples from healthy animals. Based on 71 clinical mastitis samples and 180 milk samples from clinically healthy quarters, the area under the receiver-operating characteristic curve was estimated to be between 0.88 and 0.90, and at a threshold of 38 fluorescence per minute the test had a specificity of 0.99 at a sensitivity of 0.58. Protease activity measured in fresh milk from clinically healthy cows was significantly associated with somatic cell count and parity, but not with electrical conductivity, whereas protease activity in milk that had been frozen was statistically significantly associated with all 3 parameters. This study indicates that protease activity measurement as a stand-alone test can be used for detecting mastitis samples, using milk samples that have been frozen. Because protease activity acts in part on a different biological mechanism than somatic cell count or electrical conductivity, this test may increase the accuracy of mastitis diagnosis in combination with currently available in- or on-line tests in automated milking systems.

    Full Text Available Abstract Background Several management and environmental factors are known as contributory causes of clinical mastitis in dairy herd. The study objectives were to describe the structure of herd-specific mastitis management and environmental factors and to assess the relevance of these herd-specific indicators to mastitis incidence rate. Methods Disease reports from the Danish Cattle Data Base and a management questionnaire from 2,146 herds in three Danish regions were analyzed to identify and characterize risk factors of clinical mastitis. A total of 94 (18 continuous and 76 discrete management and production variables were screened in separate bivariate regression models. Variables associated with mastitis incidence rate at a p-value Results Three latent factors (quality of labor, region of Denmark and claw trimming, and quality of outdoor holding area were identified from 14 variables. Daily milk production per cow, claw disease, quality of labor and region of Denmark were found to be significantly associated with mastitis incidence rate. A common multiple regression analysis with backward and forward selection procedures indicated there were 9 herd-specific risk factors. Conclusion Though risk factors ascertained by farmer-completed surveys explained a small percentage of the among-herd variability in crude herd-specific mastitis rates, the study suggested that farmer attitudes toward mastitis and lameness treatment were important determinants for mastitis incidence rate. Our factor analysis identified one significant latent factor, which was related to labor quality on the farm.

    Mastitis is a common and costly production disease on dairy farms. In Canada, the incidence rate of clinical mastitis (IRCM) has been determined for conventionally managed dairy farms; however, no studies to date have assessed rates in organically managed systems. The objectives of this observational study were (1) to determine the producer-reported IRCM and predominant pathogen types on conventional and organic dairy farms in Southern Ontario, Canada, and (2) to evaluate the association of both mean overall IRCM and pathogen-specific IRCM with management system, housing type, and pasture access. Data from 59 dairy farms in Southern Ontario, Canada, distributed across conventional (n=41) and organic management (n=18) systems, were collected from April 2011 to May 2012. In addition to management system, farms were categorized by housing method (loose or tie-stall) and pasture access for lactating cows. Participating producers identified and collected samples from 936 cases of clinical mastitis. The most frequently isolated mastitis pathogens were coagulase-negative staphylococci, Bacillus spp., Streptococcus spp., Staphylococcus aureus, and Escherichia coli. The IRCM was higher on conventional farms than organic (23.7 vs. 13.2 cases per 100 cow-years) and was not associated with housing type (loose or tie-stall), pasture access, or herd-average milk yield. Bulk tank somatic cell count tended to be lower on conventional farms than organic (222,000 vs. 272,000cells/mL). Pathogen-specific IRCM attributed to Staph. aureus, Bacillus spp., and E. coli was greater on conventional than organic farms, but was not associated with housing or any other factors. In conclusion, organic management was associated with reduced overall and pathogen-specific IRCM. PMID:26686728

    Bangladesh has a large population of goats, which contribute to the income, nutrition and welfare of the households of many families. Mastitis in goats has a low incidence, but is often very severe, making veterinary care necessary. The aim of this study was to identify seasonality and risk factors for goat mastitis in a hospital-based matched case-control study in a teaching veterinary hospital in Chittagong, Bangladesh and to describe the range of antimicrobial treatments applied in this situation. Cases of mastitis and controls were drawn from the hospital patient recording system, along with their risk factor status. Multiple imputation was applied to deal with the missing values in the data analysis. Mastitis occurred somewhat more in the rainy season, and comprised about 3% of all goats admitted to the hospital during January 2011-June 2014. Free-ranging farming system, poor body condition score and non-native goat breeds were significantly associated with case status. Treatment of clinical mastitis was variable and unsystematic, but the use of gentamicin was commonly recorded. The need for more prudent and evidence-based antimicrobial therapies is discussed.

    Tuberculosis (TB) of the breast is a rare entity, and can be confused with many other breast disorders, like mamma carcinoma or inflammatory breast cancer. When finding granulomatous mastitis (GM) on histology, it is important to make a differential diagnosis and seek actively for clues on the presence of tuberculosis, sarcoidosis, Wegener's granulomatosis, or idiopathic granulomatous mastitis, since treatment strategies differ and maltreatment has major implications on morbidity and mortality. An extensive clinical evaluation, laboratory work up, and imaging will lead in most cases to the right diagnosis. Anti-tuberculous therapy is the core treatment for breast TB, and surgery is indicated for extensive or persistent residual disease. Here we present a case of tuberculous mastitis and a review of literature on GM. PMID:25056489

    To evaluate if Swedish veterinary guidelines on use of antimicrobials in cases of clinical mastitis in dairy cows have been adopted by veterinary practitioners, their treatment strategies were evaluated in a cross-sectional study using a web-based questionnaire. Another aim was to study if the strategies differed among veterinarians due to year and country of exam, sex, region, numbers of mastitis cases per month, and postgraduate training in herd health using multivariable logistic regression models. In total, 267 of 741 (36 per cent) veterinarians contacted answered the questionnaire satisfactorily. Most considered bacteriological diagnostics important, but many veterinarians made treatment decisions without collecting information on antimicrobial susceptibility. Moreover, few veterinarians used measuring tape to assess bodyweight before dosing parenteral antimicrobials. Year of exam and postgraduate training were the veterinary demographic factors associated with most treatment routines. The questions associated with most demographic factors were if antimicrobial treatment is affected by knowledge on earlier udder pathogens in the herd, and how often NSAID and follow-up of treatment using milk somatic cell count are used. Overall, the veterinarians followed the Swedish guidelines rather well, but discrepancies in need for improvement were found. PMID:26864025

In the course of one year, 80 samples were taken at investigated farms from udder quarters of cows with clinical mastitis and 160 samples from udder quarters of cows with subclinical mastitis. The efficacy of three preparations, A, B, and C, was examined in the treatment of clinical and subclinical mastitis in cows. The investigations indicate that antibiotic preparation A (neomycin, polimixine B, oleandomycin and prednisolone exhibited a greater efficacy in the treatment of clinical mastitis caused by Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis and Micrococcus sp., but a smaller efficacy in the treatment of subclinical mastitis caused by Staphylococcus aureus. Preparation B (amoxicillin, clavulanic acid and prednisolone exhibited a higher efficacy in the treatment of clinical mastitis caused by Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis and Micrococcus, but a weaker effect in the treatment of subclinical mastitis caused by Staphylococcus aureus. Preparation C (procaine penicillin G, streptomycin, neomycin sulfate and prednisolone acetate exihibited efficacy in the treatment of clinical and subclinical mastitis caused by Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis, Micrococcus, Staphylococcus aureus and Esherichie coli.

    A blinded, negative controlled, randomized intervention study was undertaken to test the hypothesis that addition of meloxicam, a nonsteroidal anti-inflammatory drug, to antimicrobial treatment of mild to moderate clinical mastitis would improve fertility and reduce the risk of removal from the herd. Cows (n=509) from 61 herds in 8 regions (sites) in 6 European countries were enrolled. Following herd-owner diagnosis of mild to moderate clinical mastitis within the first 120d of lactation in a single gland, the rectal temperature, milk appearance, and California Mastitis Test score were assessed. Cows were randomly assigned within each site to be treated either with meloxicam or a placebo (control). All cows were additionally treated with 1 to 4 intramammary infusions of cephalexin and kanamycin at 24-h intervals. Prior to treatment and at 14 and 21d posttreatment, milk samples were collected for bacteriology and somatic cell count. Cows were bred by artificial insemination and pregnancy status was subsequently defined. General estimating equations were used to determine the effect of treatment (meloxicam versus control) on bacteriological cure, somatic cell count, the probability of being inseminated by 21d after the voluntary waiting period, the probability of conception to first artificial insemination, the number of artificial insemination/conception, the probability of pregnancy by 120 or 200d postcalving, and the risk of removal by 300d after treatment. Cox's proportional hazards models were used to test the effect of treatment on the calving to first insemination and calving to conception intervals. Groups did not differ in terms of age, clot score, California Mastitis Test score, rectal temperature, number of antimicrobial treatments given or bacteria present at the time of enrollment, but cows treated with meloxicam had greater days in milk at enrollment. Cows treated with meloxicam had a higher bacteriological cure proportion than those treated with the placebo [0.66 (standard error=0.04) versus 0.50 (standard error=0.06), respectively], although the proportion of glands from which no bacteria were isolated posttreatment did not differ between groups. No difference was observed in the somatic cell count between groups pre- or posttreatment. The proportion of cows that underwent artificial insemination by 21d after the voluntary waiting period was unaffected by treatment. Treatment with meloxicam was associated with a higher proportion of cows conceiving to their first artificial insemination (0.31 versus 0.21), and a higher proportion of meloxicam-treated cows were pregnant by 120d after calving (0.40 versus 0.31). The number of artificial inseminations required to achieve conception was lower in the meloxicam compared with control cows (2.43 versus 2.92). No difference was observed between groups in the proportion of cows pregnant by 200d after calving or in the proportion of cows that were culled, died, or sold by 300d after calving (17% versus 21% for meloxicam versus control, respectively). It was concluded that use of meloxicam, in conjunction with antimicrobial therapy, for mild to moderate cases of clinical mastitis, resulted in a higher probability of bacteriological cure, an increased probability of conception to first artificial insemination, fewer artificial inseminations, and a greater proportion of cows pregnant by 120d in milk.

    Full Text Available Staphylococcus aureus is one of the most frequent mastitis causative agents in small ruminants. The expression of most virulence genes of S. aureus is controlled by an accessory gene regulator (agrlocus. This study aimed to ascertain the prevalence of the different agr groups and to evaluate the occurrence of encoding genes for cytotoxin, adhesins and toxins with superantigen activity in S. aureus isolates from milk of ewes with clinical and subclinical mastitis in sheep flocks raised for meat production The agr groups I and II were identified in both cases of clinical and subclinical mastitis. Neither the arg groups III and IV nor negative agr were found. The presence of cflA gene was identified in 100% of the isolates. The frequency of hla and lukE-D genes was high -77.3 and 82.8%, respectively and all isolates from clinical mastitis presented these genes. The sec gene, either associated to tst gene or not, was identified only in isolates from subclinical mastitis. None of the following genes were identified: bbp, ebpS, cna, fnbB, icaA, icaD, bap, hlg, lukM-lukF-PV and se-a-b-d-e.

    2014-11-01

    The objective of this study was to estimate the effects of pathogen-specific clinical mastitis (CM), occurring in different weekly intervals before or after artificial insemination (AI), on the probability of conception in Holstein cows. Clinical mastitis occurring in weekly intervals from 6 wk before until 6 wk after AI was modeled. The first 4 AI in a cow's lactation were included. The following categories of pathogens were studied: Streptococcus spp. (comprising Streptococcus dysgalactiae, Streptococcus uberis, and other Streptococcus spp.); Staphylococcus aureus; coagulase-negative staphylococci (CNS); Escherichia coli; Klebsiella spp.; cases with CM signs but no bacterial growth (above the level that can be detected from our microbiological procedures) observed in the culture sample and cases with contamination (≥ 3 pathogens in the sample); and other pathogens [including Citrobacter, yeasts, Trueperella pyogenes, gram-negative bacilli (i.e., gram-negative organisms other than E. coli, Klebsiella spp., Enterobacter, and Citrobacter), Corynebacterium bovis, Corynebacterium spp., Pasteurella, Enterococcus, Pseudomonas, Mycoplasma, Prototheca, and others]. Other factors included in the model were parity (1, 2, 3, 4 and higher), season of AI (winter, spring, summer, autumn), day in lactation of first AI, farm, and other non-CM diseases (retained placenta, metritis, ketosis, displaced abomasum). Data from 90,271 AI in 39,361 lactations in 20,328 cows collected from 2003/2004 to 2011 from 5 New York State dairy farms were analyzed in a generalized linear mixed model with a Poisson distribution. The largest reductions in probability of conception were associated with CM occurring in the week before AI or in the 2 wk following AI. Escherichia coli and Klebsiella spp. had the greatest adverse effects on probability of conception. The probability of conception for a cow with any combination of characteristics may be calculated based on the parameter estimates. These findings may be helpful to farmers in assessing reproduction in their dairy cows for more effective cow management. PMID:25173468

    2014-03-01

    The objective of this study was to estimate the effects of clinical mastitis (CM) cases due to different pathogens on milk yield in Holstein cows. The first 3 CM cases in a cow's lactation were modeled. Eight categories of pathogens were included: Streptococcus spp.; Staphylococcus aureus; coagulase-negative staphylococci (CNS); Escherichia coli; Klebsiella spp.; cases with CM signs but no bacterial growth (above the level detectable by our microbiological procedures) observed in the culture sample, and cases with contamination (≥ 3 pathogens in the sample); other pathogens that may be treated with antibiotics (included Citrobacter, Corynebacterium bovis, Enterobacter, Enterococcus, Pasteurella, Pseudomonas; "other treatable"); and other pathogens not successfully treated with antibiotics (Trueperella pyogenes, Mycoplasma, Prototheca, yeasts; "other not treatable"). Data from 38,276 lactations in cows from 5 New York State dairy herds, collected from 2003-2004 until 2011, were analyzed. Mixed models with an autoregressive correlation structure (to account for correlation among the repeated measures of milk yield within a lactation) were estimated. Primiparous (lactation 1) and multiparous (lactations 2 and 3) cows were analyzed separately, as the shapes of their lactation curves differed. Primiparas were followed for up to 48 wk of lactation and multiparas for up to 44 wk. Fixed effects included parity, calving season, week of lactation, CM (type, case number, and timing of CM in relation to milk production cycle), and other diseases (milk fever, retained placenta, metritis, ketosis, displaced abomasum). Herd was modeled as a random effect. Clinical mastitis was more common in multiparas than in primiparas. In primiparas, Streptococcus spp. occurred most frequently as the first case. In multiparas, E. coli was most common as the first case. In subsequent cases, CM cases with no specific growth or contamination were most common in both parity groups. The hazard of CM increased with case number. Mastitic cows were generally higher producers before the CM episode than their nonmastitic herdmates. Milk loss varied with pathogen and case number. In primiparas, the greatest losses were associated with E. coli and "other not treatable" organisms. In multiparas, the greatest losses were associated with Klebsiella spp. and "other not treatable" organisms. Milk loss was not associated with occurrence of CNS. The findings may help farmers to make optimal management decisions for their cows. PMID:24418269

    Increasing dairy farm size and increase in automation in livestock production require that new methods are used to monitor animal health. In this study, a thermal camera was tested for its capacity to detect clinical mastitis. Mastitis was experimentally induced in 6 cows with 10 microg of Escherichia coli lipopolysaccharide (LPS). The LPS was infused into the left forequarter of each cow, and the right forequarters served as controls. Clinical examination for systemic and local signs and sampling for indicators of inflammation in milk were carried out before morning and evening milking throughout the 5-d experimental period and more frequently on the challenge day. Thermal images of experimental and control quarters were taken at each sampling time from lateral and medial angles. The first signs of clinical mastitis were noted in all cows 2 h postchallenge and included changes in general appearance of the cows and local clinical signs in the affected udder quarter. Rectal temperature, milk somatic cell count, and electrical conductivity were increased 4 h postchallenge and milk N-acetyl-beta-D-glucosaminidase activity 8 h postchallenge. The thermal camera was successful in detecting the 1 to 1.5 degrees C temperature change on udder skin associated with clinical mastitis in all cows because temperature of the udder skin of the experimental and control quarters increased in line with the rectal temperature. Yet, local signs on the udder were seen before the rise in udder skin and body temperature. The udder represents a sensitive site for detection of any febrile disease using a noninvasive method. A thermal camera mounted in a milking or feeding parlor could detect temperature changes associated with clinical mastitis or other diseases in a dairy herd. PMID:19038934

    Mastitis is a complex disease affecting dairy cows and is considered to be the most costly disease of dairy herds. The hazard of mastitis is a function of many factors, both managerial and environmental, making its control a difficult issue to milk producers. Observational studies of clinical mastitis (CM) often generate datasets with a number of characteristics which influence the analysis of those data: the outcome of interest may be the time to occurrence of a case of mastitis, predictors may change over time (time-dependent predictors), the effects of factors may change over time (time-dependent effects), there are usually multiple hierarchical levels, and datasets may be very large. Analysis of such data often requires expansion of the data into the counting-process format - leading to larger datasets - thus complicating the analysis and requiring excessive computing time. In this study, a nested frailty Cox model with time-dependent predictors and effects was applied to Canadian Bovine Mastitis Research Network data in which 10,831 lactations of 8035 cows from 69 herds were followed through lactation until the first occurrence of CM. The model was fit to the data as a Poisson model with nested normally distributed random effects at the cow and herd levels. Risk factors associated with the hazard of CM during the lactation were identified, such as parity, calving season, herd somatic cell score, pasture access, fore-stripping, and proportion of treated cases of CM in a herd. The analysis showed that most of the predictors had a strong effect early in lactation and also demonstrated substantial variation in the baseline hazard among cows and between herds. A small simulation study for a setting similar to the real data was conducted to evaluate the Poisson maximum likelihood estimation approach with both Gaussian quadrature method and Laplace approximation. Further, the performance of the two methods was compared with the performance of a widely used estimation approach for frailty Cox models based on the penalized partial likelihood. The simulation study showed good performance for the Poisson maximum likelihood approach with Gaussian quadrature and biased variance component estimates for both the Poisson maximum likelihood with Laplace approximation and penalized partial likelihood approaches.

    The objective of this study was to investigate the genetic relationships of the 3 most frequently reported dairy cattle diseases (clinical mastitis, cystic ovaries, and lameness) with test-day milk yield and somatic cell score (SCS) in first-lactation Canadian Holstein cows using random regression models. Health data recorded by producers were available from the National Dairy Cattle Health System in Canada. Disease traits were defined as binary traits (0=healthy, 1=affected) based on whether or not the cow had at least one disease case recorded within 305 d after calving. Mean frequencies of clinical mastitis, cystic ovaries, and lameness were 12.7, 8.2, and 9.1%, respectively. For genetic analyses, a Bayesian approach using Gibbs sampling was applied. Bivariate linear sire random regression model analyses were carried out between each of the 3 disease traits and test-day milk yield or SCS. Random regressions on second-degree Legendre polynomials were used to model the daily sire additive genetic and cow effects on test-day milk yield and SCS, whereas only the intercept term was fitted for disease traits. Estimated heritabilities were 0.03, 0.03, and 0.02 for clinical mastitis, cystic ovaries, and lameness, respectively. Average heritabilities for milk yield were between 0.41 and 0.49. Average heritabilities for SCS ranged from 0.10 to 0.12. The average genetic correlations between daily milk yield and clinical mastitis, cystic ovaries, and lameness were 0.40, 0.26, and 0.23, respectively; however, the last estimate was not statistically different from zero. Cows with a high genetic merit for milk yield during the lactation were more susceptible to clinical mastitis and cystic ovaries. Estimates of genetic correlations between daily milk yield and clinical mastitis were moderate throughout the lactation. The genetic correlations between daily milk yield and cystic ovaries were near zero at the beginning of lactation and were highest at mid and end lactation. The average genetic correlation between daily SCS and clinical mastitis was 0.59 and was consistent throughout the lactation. The average genetic correlation between daily SCS and cystic ovaries was near zero (-0.01), whereas a moderate, but nonsignificant, correlation of 0.27 was observed between SCS and lameness. Unfavorable genetic associations between milk yield and diseases imply that production and health traits should be considered simultaneously in genetic selection. PMID:24996282

    Full Text Available Aim: Mastitis is recognized as one of the most costly health disorder affecting dairy cows. An epidemiological study was carried out at some selected farms in Chittagong district of Bangladesh to determine the prevalence and risk factors of sub-clinical mastitis (SCM in dairy cows. Materials and Methods: For conducting the study, some dairy farms of Chittagong were selected from urban and periurban areas by stratified random sampling. A total of 444 quarter samples of 111 (56 from commercial dairy farms and 55 from backyards lactating dairy cows were considered. Sub-clinical mastitis (SCM was determined using three different indirect screening tests: California Mastitis Test (CMT, White Slide Test (WST and Surf Field Mastitis Test (SFMT. Sensitivity and specificity were also determined to measure the accuracy of those tests. Results: The prevalence of SCM by CMT, WST and SFMT were 32.43% (n=144, 33.56% (n=149 and 31.53% (n=140, respectively. Distribution of SCM in relation to different variables at quarter level and animal level was also recorded. The prevalence of SCM was significantly (P4 than others at quarter level. No significant difference (P>0.05 was found in relation to breed. Using CMT as a gold standard, sensitivity and specificity of WST and SFMT were also calculated at 95% confidence interval. The sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, positive predictive value, negative predictive value and disease prevalence by WST and SFMT were comparable. Conclusion: This study recommends that regular screening of sub-clinical mastitis will reduce the prevalence of sub-clinical mastitis. The most effective way to control sub-clinical mastitis is to take preventive measures such as regular cleaning of the floor, keeping the udder clean, milkman's cleanliness, dry cow therapy specially in high yielding dairy cows.

    The objective of this study was to determine cow characteristics and farm management factors during the dry period associated with early postparturient intramammary infection (IMI) and subsequent clinical mastitis (CM). Data were collected three times: before drying off (P1), during the dry period (P2), and 5 to 14 days after calving (P3), using questionnaires and farm investigation. Milk samples were aseptically collected for bacterial identification at P1 and P3. Factors associated with IMI and CM were analyzed using multiple logistic regression models. The final model showed that IMI in early postpartum was significantly associated with full insertion of dry cow antibiotic, dry cows in barns with a combination of tie and free stalls, body condition score (BCS) in dry period and after calving, and milk yield before drying off. For IMI cows, factors significantly associated with clinical expression of mastitis were having daily barn cleaning, teat disinfected with alcohol before administration of dry cow therapy, BCS before drying off, milk yield before drying off, and days in milk at drying off. In conclusion, both cow and farm management factors are associated with the IMI rate and subsequent expression of clinical signs of mastitis in early postpartum cows. PMID:26949960

    Automatic milking systems (AMS) generate alert lists reporting cows likely to have clinical mastitis (CM). Dutch farmers indicated that they use non-AMS cow information or the detailed alert information from the AMS to decide whether to check an alerted cow for CM. However, it is not yet known to what extent such information can be used to discriminate between true-positive and false-positive alerts. The overall objective was to investigate whether selection of the alerted cows that need further investigation for CM can be made. For this purpose, non-AMS cow information and detailed alert information were used. During a 2-yr study period, 11,156 alerts for CM, including 159 true-positive alerts, were collected at one farm in The Netherlands. Non-AMS cow information on parity, days in milk, season of the year, somatic cell count history, and CM history was added to each alert. In addition, 6 alert information variables were defined. These were the height of electrical conductivity, the alert origin (electrical conductivity, color, or both), whether or not a color alert for mastitic milk was given, whether or not a color alert for abnormal milk was given, deviation from the expected milk yield, and the number of alerts of the cow in the preceding 12 to 96 h. Subsequently, naive Bayesian networks (NBN) were constructed to compute the posterior probability of an alert being truly positive based only on non-AMS cow information, based on only alert information, or based on both types of information. The NBN including both types of information had the highest area under the receiver operating characteristic curve (AUC; 0.78), followed by the NBN including only alert information (AUC=0.75) and the NBN including only non-AMS cow information (AUC=0.62). By combining the 2 types of information and by setting a threshold on the computed probabilities, the number of false-positive alerts on a mastitis alert list was reduced by 35%, and 10% of the true-positive alerts would not be identified. To detect CM cases at a farm with an AMS, checking all alerts is still the best option but would result in a high workload. Checking alerts based on a single alert information variable would result in missing too many true-positive cases. Using a combination of alert information variables, however, is the best way to select cows that need further investigation. The effect of adding non-AMS cow information on making a distinction between true-positive and false-positive alerts would be minor. PMID:20494164

    The clinical, epidemiological and pathological aspects of protothecal mastitis in a Brazilian dairy herd are described. Prototheca zopfii infection was diagnosed in 11 of 121 milking cows. Clinical mastitis refractory to usual therapy was observed in 7 cows. Several environmental conditions conducive to the growth of Prototheca spp., such as wetness, muddiness and the presence of organic material, were present in the dairy. Improper milking practices and insanitary infusion of the intramammary antibiotics were also observed. Six cows with protothecal mastitis were slaughtered and the affected quarters of each cow were examined by histology and immunohistochemical staining for bovine keratin and P. zopfii. The histological lesions were characterized by interstitial infiltrates of macrophages, plasma cells and lymphocytes; algae were seen in the alveolar lumen and interstitium. The lack of a positive reaction with an antiserum against bovine keratin in the mammary alveolar epithelial layer in some affected areas suggests destruction of milk-producing tissues, which may be related to the low milk production observed. The algal organisms stained positively with a polyclonal antibody against P. zopfii. PMID:11770201

    The objectives of this study were to characterize 60-d outcomes after treatment of mild (abnormal milk) and moderate (abnormal milk and abnormal udder) cases of clinical mastitis (CM) occurring in a single quarter of cows on Wisconsin farms (n=4) and to determine risk factors associated with those outcomes. Duplicate milk samples were collected from the affected quarter of each cow for microbiological analysis at the onset of CM (PRE) and 21 d later (POST). Cows were treated only in the affected quarter using an intramammary product containing 125 mg of ceftiofur. Bacteriological cure was defined as absence of pathogens in the POST sample obtained from the enrolled quarter. Recurrence was defined for the cow when CM occurred after the milk-withholding period for the enrolled case of CM. Retention in the herd was defined when a cow was retained within the herd for the 60-d follow-up period. Somatic cell count reduction (SCCR) was defined at the cow level as somatic cell count (SCC) below 200,000 cells/mL at the Dairy Herd Improvement Association test day occurring between 21 to 55 d post-treatment. The effects of farm, days in milk, parity, severity, microbiological diagnosis at PRE, previous milk yield, previous SCC, previous occurrence of CM and treatment duration on selected post-treatment outcomes were assessed using Chi-squared analysis and logistic regression. Microbiological results at PRE were distributed as: Escherichia coli (n=14), Klebsiella spp. (n=11), Enterobacter spp. (n=8), Serratia spp. (n=7), other gram-negative species (n=3), Streptococcus spp. (n=25), coagulase-negative staphylococci (n=4); Staphylococcus aureus (n=1); Streptococcus agalactiae (n=1), other gram-positive species (n=9), and culture negative (n=60). Treated quarters were more likely to experience bacteriological cure when the cow experienced CM for the first time in the lactation and when no pathogen was recovered from PRE milk samples obtained from the enrolled quarter. Parity and bacteriological cure were associated with the probability of recurrence. Greater milk yield at previous Dairy Herd Improvement test was the most important predictor for retention within the herd. When SCC before CM was >200,000 cells/mL the probability of having SCCR after treatment was decreased. When the case experienced bacteriological cure, the cow was less likely to experience recurrent cases and was more likely to have SCCR below 200,000 cells/mL. Post-treatment outcomes, such as recurrence and SCCR, are strongly associated with bacteriological cure and, when monitored, can be used to help determine if a treatment has been successful. Information about the etiology of CM, history of clinical and subclinical mastitis, and parity are useful to review when making strategic treatment decisions. PMID:21700025

It was performed at Humeimeh research station for Damascus goats, General commission for scientific agricultural research (GCSAR from February to march 2011 and done on dairy goats aged 2 to 6 years. Milk samples were taken from 134 dairy goats during morning milking according to habitual procedure and screened for evidence of subclinical mastitis by California Mastitis Test (CMT, electrical conductivity measurement (EC and lactose content (LC of milk. Positive (+1 to +3 CMT and/or high electrical conductivity milk samples were subjected to bacteriological examination to distinguish between healthy (absence of mastitis agents and infected (presence of contagious or environmental mastitis agents. The overall prevalence of subclinical mastitis was found to be 24.6%. Percentage of positive (+1 to +3, suspected and negative CMT reactions were 76.85, 8.95 and 14.2%, respectively. The values of electrical conductivity for negative, suspected and positive (+1, +2 and +3 CMT milk samples were 3.93 ± 0.64, 4.47 ± 0.61, 4.68 ± 0.72, 4.81 ± 0.76 and 6.56 ± 0.85 ms/cm, respectively. T-test has been shown statistical differences in California mastitis test reactions and electrical conductivity readings, and not statistically for milk lactose content, between positive and negative results for bacterial growth. Intramammary infection was found in 40.9% milk samples caused by Staphylococcus (75%, alone E. coli (16.6% or associated with streptococci (8.3%.

    The US regulations for production of organic milk include a strict prohibition against the use of antimicrobials and other synthetic substances. The effect of these regulations on dairy animal health has not been previously reported. The objective of this study was to characterize disease detection and identify risk factors for selected diseases on organic (ORG) and similarly sized conventional (CON) farms. Dairy herds (n=292) were enrolled across 3 states (New York, Oregon, Wisconsin) with CON herds matched to ORG herds based on location and herd size. During a single herd visit, information was collected about herd management practices and animal disease occurring in the previous 60 d, and paperwork was left for recording disease occurrences during 60 d after the visit. For analysis, CON herds were further divided into grazing and nongrazing. Poisson regression models were used to assess risk factors for rate of farmer-identified and recorded cases of clinical mastitis, ketosis, and pneumonia. An increased rate of farmer-identified and recorded cases of clinical mastitis was associated with use of CON management, use of forestripping, presence of contagious pathogens in the bulk tank culture, proactive detection of mastitis in postpartum cows, and stall barn housing. An increased rate of farmer-identified and recorded cases of ketosis was associated with having a more sensitive definition of ketosis, using stall barn housing, and feeding a greater amount of concentrates. An increased rate of farmer-identified and recorded cases of pneumonia was associated with a lack of grazing, small or medium herd size, and Jersey as the predominant breed. Overall, disease definitions and perceptions were similar among grazing systems and were associated with the rate of farmer-identified and recorded cases of disease. PMID:23684015

    This study explored the potential value of in-line composite somatic cell count (ISCC) sensing as a sole criterion or in combination with quarter-based electrical conductivity (EC) of milk, for automatic detection of clinical mastitis (CM) during automatic milking. Data generated from a New Zealand research herd of about 200 cows milked by 2 automatic milking systems during the 2006-2007 milking season included EC, ISCC, monthly laboratory-determined SCC, and observed cases of CM that were treated with antibiotics. Milk samples for ISCC and laboratory-determined SCC were taken sequentially at the end of a cow milking. Both samples were derived from a composite cow milking obtained from the bottom of the milk receiver. Different time windows were defined in which true-positive, false-negative, and false-positive alerts were determined. Quarters suspected of having CM were visually checked and, if CM was confirmed, sampled for bacteriological culturing and treated with an antibiotic treatment. These treated quarters were considered as gold-standard positives for comparing CM detection models. Alert thresholds were adjusted to achieve a sensitivity of 80% in 3 detection models: using ISCC alone, EC alone, or a combination of these. The success rate (also known as the positive predictive value) and the false alert rate (number of false-positive alerts per 1,000 cow milkings) were used to evaluate detection performance. Normalized ISCC estimates were highly correlated with normalized laboratory-determined SCC measurements (r = 0.82) for SCC measurements >200 x 10(3) cells/mL. Using EC alone as a detection tool resulted in a range of 6.9 to 11.0% for success rate, and a range of 4.7 to 7.8 for the false alert rate. Values for the ISCC model were better than the model using EC alone with 12.7 to 15.6% for the success rate and 2.9 to 3.7 for the false alert rate. Combining sensor information to detect CM, by using a fuzzy logic algorithm, produced a 2- to 3-fold increase in the success rate (range 21.9 to 32.0%) and a 2- to 3-fold decrease in the false alert rate (range 1.2 to 2.1) compared with the models using ISCC or EC alone. Results suggest that the performance of a CM detection system improved when ISCC information was added to a detection model using EC information. PMID:19038931

    Full Text Available Factors relating to the occurrence of mastitis were studied on 12 Irish dairy herds with histories of elevated somatic cell count (SCC and/or increased incidence of clinical mastitis cases. Milk recording data were analysed, housing conditions and calving areas were examined; dry cow therapy, clinical mastitis records, milking technique and aspects of milking machine function were assessed. Herds with a ratio of less than 110 cubicles per 100 cows were more likely to experience environmental mastitis. Herds with inadequate calving facilities, where cows spent prolonged periods on straw bedding, were likely to acquire environmental mastitis. In the majority of the herds, the selection of dry cow therapy lacked adequate planning. The majority of farmers took no action to reduce pain experienced by cows suffering mastitis. Deficiencies in parlour hygiene were evident in all herds experiencing elevation in SCC.

    Mastitis is a frequent problem among dairy cows, reducing milk yield and increasing cull rates. Systemic therapy with the cephalosporin antimicrobial ceftiofur hydrochloride (CEF) may improve therapeutic outcomes, but the incidence of CEF violative residues has increased annually since 2011. One potential explanation is that disease status may alter the pharmacokinetics (PK) of CEF. To test this hypothesis, we compared the plasma PK of CEF in healthy cows with those with severe endotoxic mastitis. Eight cows with naturally occurring mastitis and 8 clinically healthy cows were treated with 2.2 mg of CEF per kilogram of body weight once daily for 5d via the intramuscular route. Blood was collected at 0, 0.33, 0.67, 1, 1.5, 2, 3, 4, 8, 16, and 24h after the first CEF administration and every 8h thereafter until 120h after the final dose. Plasma samples were analyzed for CEF concentrations using liquid chromatography coupled with mass spectrometry. With the exception of time 0, CEF was detected at all time points. The disease group had a significantly higher plasma CEF concentration at t=3h after the first injection and a significantly lower plasma concentration from 40 to 152h following the first injection, with the exception of the t=64h time point. Data following the first injection (time 0-24 h) were fit to a single-dose, noncompartmental PK model. This model indicated that the disease group had a shorter plasma half-life. A multidose, noncompartmental model was used to determine steady-state PK. Compared with control cows, the disease group had an initially higher peak concentration and a higher volume of distribution and drug clearance rates. The disease group also had a lower area under the curve per dosing interval, steady-state concentration maximum, and dose-adjusted peak steady-state concentration. All other PK parameters were not different between the 2 groups. Altered PK, as suggested by this trial, may contribute to an increased risk for the development of a violative residue in meat. Further research is needed to more completely characterize drug distribution in diseased cattle and to study the effect of coadministration of other drugs on drug distribution. PMID:26601579

    The aim of the present study was to examine changes in innate immune factors in the milk of mastitic dairy cows treated with antibiotics. Cows in the antibiotics group (n = 13) were infused into the mammary gland with cefazolin on the sixth day after mastitis was diagnosed (the day of the mastitis diagnosis = day -6). The control group (n = 12) was not treated. Milk samples were collected once every 2 days from days -6 to 12 and somatic cell count (SCC), lingual antimicrobial peptide (LAP), and lactoferrin (LF) concentrations and lactoperoxidase (LPO) activity were measured. SCC and LF concentrations in the antibiotics group markedly decreased after the antibiotic treatment. When cows in the antibiotics group were divided according to SCC on day 0, LAP concentrations and LPO activity in cows with a lower SCC on day 0 (<5 × 10(6) cell/mL) were significantly higher and lower than those in cows with a higher SCC, respectively. These results suggest that LF concentration decreased with decrease in SCC after treatment and that LAP concentration and LPO activity differed depending on the severity of mastitis. This is the first report to reveal the dynamics of innate immune factor in milk of cows treated for clinical mastitis. PMID:25185977

    International Nuclear Information System (INIS)

    The present study was undertaken to determine the distribution and genotypic characteristics of Staphylococcus aureus isolates recovered from naturally occurring mastitis in cattle and buffaloes. For this purpose a total of 1445 lactating cattle (653) and buffaloes (792) present at two experimental livestock farms Okara (Bahadarnagar) and Sahiwal (Qadiarabad), in and around district Faisalabad and slaughtered at an abattoir due to low milk yield and were screened for mastitis. California Mastitis Test (CMT) was used to detect sub clinical mastitis. The positive quarter milk samples were collected for culturing of S. aureus isolates. taphylococcus aureus isolates were identified on the basis of growth features, biochemical characteristics, coagulase test and as well as amplification of coagulase (coa) and spa (spa-X) genes specific to its virulence. S. aureus isolates (n=265) were characterized by Polymerase chain reaction to determine the frequency of coagulase (coa) and spa (spa-X) genes. From these isolates the amplification of the coagulase (coa) gene yielded three different PCR products approximately 204bp to 490bp while spa (spa-X) gene produced five different products ranging in size from 190bp to 320bp. PCR revealed that from all the coagulase positive S. aureus isolates 261(98.5%) had spa (spa-X) gene. The results of the present study indicated that S. aureus isolates recovered from bovine mastitis were genetically different within and among the various herds which may provide essential and valuable strategies to control staphylococcal infections in future.

    The aim of this study was to evaluate whether it was possible to (1) estimate the clinical mastitis incidence rate (CMI) for all Dutch dairy herds and (2) to detect farms with a high CMI based on routinely collected herd data. For this study, 240 dairy farms with a conventional milking system that participated in the milk recording program every 4 to 6 wk were randomly selected and agreed to participate. From the initial 240 herds, data of clinical mastitis (CM) registrations and routinely collected herd data of 227 herds were complete and could be used for analysis. Routinely collected herd data consisted of identification and registration records, antimicrobial usage, test-day records from the milk recording program, bulk tank milk (BTM) somatic cell count data and results of diagnostic tests on BTM samples. For each of the 227 herds, the CMI per 100 cows per year was calculated per quarter of the year and was combined with the available herd data. Two models were developed to predict the CMI for all dairy herds and to detect individual herds that belonged to the 25% herds with the highest CMI. Records of 156 (67%) herds were used for development of the models and the remaining 71 (33%) were used for validation. The model that estimated the CMI in all herds consisted of 11 explanatory variables. The observed and predicted averages of the validation herds were not significantly different. The model estimated a CMI per 100 cows per year of 32.5 cases (95% confidence interval=30.2-34.8), whereas the farmers registered 33.4 cases (95% confidence interval=29.5-37.4). The model that aimed at detecting individual herds with a high CMI contained 6 explanatory variables and could correctly classify 77% of all validation herds at the quarter-year level. The most important variables in the model were antibiotic usage for treating CM and BTM somatic cell count. In conclusion, models based on routinely collected herd data gave an accurate prediction of CMI for all Dutch dairy herds and could detect individual dairy herds with a high CMI. With these models it is possible to periodically monitor CMI both at the herd and at the national level, which is valuable for monitoring purposes and can motivate farmers to continuously improve udder health in their herds.

    Full Text Available In response to farmer requests after milk from their herds was rejected by processors due to poor quality, a study was carried out from April to October 2011 to determine the prevalence of sub clinical mastitis, associated risk factors and causative micro-organisms. Samples were collected from 195 dairy cows on 23 randomly selected dairy farms delivering milk to Isangano, Kirebe and Nyagatare milk collection centres in Nyagatare District, Rwanda. The Draminski® Mastitis Detector was used to detect sub clinical mastitis in individual cows based on milk electrical conductivity changes. Risk factors for mastitis that were evaluated included teat-end condition, cow dirtiness, breed, parity, age and stage of lactation. Relationships of these factors with mastitis status were determined using Chi-square analysis, and relative importance as causes of mastitis was assessed using logistic regression. Samples from 16 sub clinical mastitis positive dairy cows were analysed to identify causative micro-organisms using Dairy Quality Control Inspection analytical kits. Sub clinical mastitis prevalence was 52% across the farms. It was higher with increases in, amongst other risk factors, teat-end damage severity, cow dirtiness, and level of pure dairy breed genetics. The risk factors considered accounted for 62% of mastitis prevalence; teat-end condition alone accounted for 30%. Most of the mastitis cases (87.5% were caused by coliform bacteria. Considering that farmers are upgrading their local Ankole cows to cross-breed dairy cows that are more susceptible to mastitis, results from this study indicate the need to dip the teats of cows in sanitisers, improve cow hygiene, and introduce mastitis prevention and control programmes.

    Full Text Available A 5-year old Holstein Friesian cross breed cow was presented to Madras Veterinary College Teaching Hospital with the history of reduced milk yield. Clinical examination of udder revealed normal milk color and soft udder. The milk pH was 7.0, with California Mastitis Test score 3+, Electrical Conductivity 270U, and Somatic Cell Count as 328,000. Isolation and identification of causative agent revealed Methicillin Resistant Staphylococcus aureus (MRSA from the sub-acute mastitis sample. Agar disc diffusion method for antimicrobial susceptibility revealed that the MRSA was sensitive to Enrofloxacin, Gentamicin, Oxytetracycline and Amoxicillin+Sulbactam. On the other hand, the isolate was resistance to Amoxicillin, Penicillin G, Ceftriaxone and Methicillin. The isolate was positive for β-lactamase resistance by Nitrocefin test. The MRSA was confirmed for the presence of mecA and blaZ target genes by polymerase chain reaction (PCR. The cow was treated with Enrofloxacin, Vitamin E and inorganic Selenium, and was recovered after 5 days of post-treatment.

    Mastitis affects the quality of milk and is a potential health risk for the other cows. In a well managed dairy herd, in addition to clinical mastitis, subclinical mastitis should be efficiently detected. Bacteriological sampling is not feasible as a routine test to identify subclinical mastitis, and indirect tests of mastitis are more suitable for selecting cows with intramammary infections for subsequent bacteriological sampling. Mastitis affects the composition of milk, and the degree of c...

    Lupus mastitis is a form of lupus profundus that is seen in patients with systemic lupus erythematosus. It usually presents as a swelling (or swellings) in the breasts, with or without pain. The condition is recurrent and progresses along with the underlying disease, with fat necrosis, calcification, fibrosis, scarring, and breast atrophy. Lupus mastitis is often confused with malignancy and lymphoma and, in our part of the world, with tuberculosis. Confusion is especially likely when it occurs in an unusual clinical setting. In this article, we present a case that presented with unique radiological, pathological, and clinical features. Awareness of the various manifestations of lupus mastitis is essential if unnecessary interventions such as biopsies and surgeries, and their consequences, are to be avoided. PMID:19881078

    This study used an existing dynamic optimization model to compare costs of common treatment protocols and J5 vaccination for clinical mastitis in US dairy herds. Clinical mastitis is an infection of the mammary gland causing major economic losses in dairy herds due to reduced milk production, reduced conception, and increased risk of mortality and culling for infected cows. Treatment protocols were developed to reflect common practices in dairy herds. These included targeted therapy following pathogen identification, and therapy without pathogen identification using a broad-spectrum antimicrobial or treating with the cheapest treatment option. The cost-benefit of J5 vaccination was also estimated. Effects of treatment were accounted for as changes in treatment costs, milk loss due to mastitis, milk discarded due to treatment, and mortality. Following ineffective treatments, secondary decisions included extending the current treatment, alternative treatment, discontinuing treatment, and pathogen identification followed by recommended treatment. Average net returns for treatment protocols and vaccination were generated using an existing dynamic programming model. This model incorporates cow and pathogen characteristics to optimize management decisions to treat, inseminate, or cull cows. Of the treatment protocols where 100% of cows received recommended treatment, pathogen-specific identification followed by recommended therapy yielded the highest average net returns per cow per year. Out of all treatment scenarios, the highest net returns were achieved with selecting the cheapest treatment option and discontinuing treatment, or alternate treatment with a similar spectrum therapy; however, this may not account for the full consequences of giving nonrecommended therapies to cows with clinical mastitis. Vaccination increased average net returns in all scenarios. PMID:26947301

    Recently, many changes have been implemented in Dutch dairy herds. Herd sizes have increased and antimicrobial use has been reduced. Certain types of antimicrobials can only be used in specific circumstances, and the preventive use of antimicrobials in dry cows is prohibited. The aim of this study was to quantify clinical mastitis (CM), subclinical mastitis (SCM), and risk factors associated with CM in Dutch dairy herds in 2013, in the context of these changes. For this study, 240 dairy herds were randomly selected from farms that participated in test-day milk recording, used a conventional milking system, and agreed to participate in the study. Eventually, 233 Dutch dairy farmers had complete records of CM in their herds in 2013 and 224 of these farmers completed a questionnaire on management factors potentially associated with CM. All participating farmers gave consent to use their routinely collected herd data such as test-day records and cow identification and registration data. Clinical and subclinical mastitis incidence rate (CMI and SCMI, respectively) per 100 cows per year, subclinical mastitis prevalence, and average bulk tank milk somatic cell count were obtained for 2013. The risk factor analysis was conducted using a generalized linear model with a log link function and a negative binomial distribution on herd level in Stata 13.1. A median CMI of 28.6 per 100 cows at risk per year, SCMI of 70.1 per 100 cows at risk per year, SCM prevalence of 15.8%, and bulk tank milk somatic cell count of 171×10(3) cells/mL were observed in 2013. Factors that were significantly associated with a higher CMI were cleaning slatted floors only once per day compared with more than 4 times a day (i.e., mechanical), a higher percentage of Holstein Friesian cows present in the herd, treating less than 50% of the cows with CM with antimicrobials, postmilking teat disinfection, and treatment of cows with elevated somatic cell count with antimicrobials. The results of this study indicated that udder health had not deteriorated compared with udder health in previous Dutch studies where herd sizes were somewhat smaller and before the restrictions in antimicrobial use. Several of the risk factors that were found can be influenced by the farmer and can prevent the occurrence of CMI. Still, when cases of CM occur, treatment with antimicrobials might be necessary to cure the CM case and is beneficial for the overall udder health in the herd. PMID:26874413

    Protothecosis was described in many animals, with bovine mastitis being the main form. The increasing number of isolations of Prototheca spp. from bovine mastitis cases indicates the need of a detailed evaluation of this problem. Besides this, these algae do not respond to treatment with the antimicrobians most frequently applied, leading to elimination of the affected animals, as the best method to control the disease. In two dairy farms in the State of So Paulo, Brazil, a total of 155 lactating cows and 52 dry cows were examined. Milk samples were aseptically collected from lactating cows with clinical or subclinical mastitis. From dry cows, secretion samples from all quarters were collected. All samples were then taken to microbiological exams. At dairy farm 1, Prototheca spp. was isolated from 14.95% milk samples from lactating cows, (all of them cases of subclinical mastitis), and from 8.06% samples from dry cows. At dairy farm 2, Prototheca spp. was isolated from 5.1% milk samples and there were ten cases of clinical mastitis due to this agent. Although clinical mastitis has been considered the main form of occurrence of this pathology until now, it is important to consider Prototheca spp. as subclinical mastitis pathogen. Prototheca zopfii was the main specie isolated. In this study a high rate of intramammarian infections, as clinical or subclinical mastitis during lactation as well as in dry period, was observed, high lighting the importance of suitable diagnosis, so that control and preventive measures can be implemented to avoid dissemination of the agent.

    2015-01-01

    Streptococcus uberis is a common cause of clinical and subclinical mastitis in dairy cattle. Several virulence mechanisms have been proposed to contribute to the species' ability to cause disease. Here, virulence characteristics were compared between S. uberis strains FSL Z1-048, which consistently caused clinical mastitis in a challenge model, and FSL Z1-124, which consistently failed to cause disease in the same model, to ascertain whether in vitro virulence characteristics were related to clinical outcome. Macrophages derived from bovine blood monocytes failed to kill FSL Z1-048 whilst reducing survival of FSL Z1-124 by 42.5%. Conversely, blood derived polymorphonuclear cells caused more reduction (67.1 vs. 44.2%, respectively) in the survival of FSL Z1-048 than in survival of FSL Z1-124. After 3h of coincubation with bovine mammary epithelial cell line BME-UV1, 1000-fold higher adherence was observed for FSL Z1-048 compared to FSL Z1-124, despite presence of a frame shift mutation in the sua gene of FSL Z1-048 that resulted in predicted truncation of the S. uberis Adhesion Molecule (SUAM) protein. In contrast, FSL Z1-124 showed higher ability than FSL Z1-048 to invade BME-UV1 cells. Finally, observed biofilm formation by FSL Z1-124 was significantly greater than for FSL Z1-048. In summary, for several hypothetical virulence characteristics, virulence phenotype in vitro did not match disease phenotype in vivo. Evasion of macrophage killing and adhesion to mammary epithelial cells were the only in vitro traits associated with virulence in vivo, making them attractive targets for further research into pathogenesis and control of S. uberis mastitis.

  19. Detection of clinical mastitis with sensor data from automatic milking systems is improved by using decision-tree induction.

    2010-08-01

    The objective was to develop and validate a clinical mastitis (CM) detection model by means of decision-tree induction. For farmers milking with an automatic milking system (AMS), it is desirable that the detection model has a high level of sensitivity (Se), especially for more severe cases of CM, at a very high specificity (Sp). In addition, an alert for CM should be generated preferably at the quarter milking (QM) at which the CM infection is visible for the first time. Data were collected from 9 Dutch dairy herds milking automatically during a 2.5-yr period. Data included sensor data (electrical conductivity, color, and yield) at the QM level and visual observations of quarters with CM recorded by the farmers. Visual observations of quarters with CM were combined with sensor data of the most recent automatic milking recorded for that same quarter, within a 24-h time window before the visual assessment time. Sensor data of 3.5 million QM were collected, of which 348 QM were combined with a CM observation. Data were divided into a training set, including two-thirds of all data, and a test set. Cows in the training set were not included in the test set and vice versa. A decision-tree model was trained using only clear examples of healthy (n=24,717) or diseased (n=243) QM. The model was tested on 105 QM with CM and a random sample of 50,000 QM without CM. While keeping the Se at a level comparable to that of models currently used by AMS, the decision-tree model was able to decrease the number of false-positive alerts by more than 50%. At an Sp of 99%, 40% of the CM cases were detected. Sixty-four percent of the severe CM cases were detected and only 12.5% of the CM that were scored as watery milk. The Se increased considerably from 40% to 66.7% when the time window increased from less than 24h before the CM observation, to a time window from 24h before to 24h after the CM observation. Even at very wide time windows, however, it was impossible to reach an Se of 100%. This indicates the inability to detect all CM cases based on sensor data alone. Sensitivity levels varied largely when the decision tree was validated per herd. This trend was confirmed when decision trees were trained using data from 8 herds and tested on data from the ninth herd. This indicates that when using the decision tree as a generic CM detection model in practice, some herds will continue having difficulties in detecting CM using mastitis alert lists, whereas others will perform well.

    The purpose of this report is to evaluate the characteristic findings of tuberculosis of the breast on mammogram, sonogram, and CT and to compare the results with the imaging feature of non-tuberculous mastitis. Using mammograms and sonograms, nine cases of tuberculosis of the breast were evaluated, and for four cases, CT was used. Aspects evaluated were contour, shape and size of the lesion, homogeneity of internal content, and extension of the lesion from/to the adjacent organs. Diagnosis was based on aspiration, surgery, and pathologic findings including acid-fast bacillus (AFB) staining. Mammograms and sonograms of 19 patients with non-tuberculous mastitis of the breast were reviewed. No cases of tuberculous mastitis presented clinical evidence of acute inflammation such as fever, swelling or skin redness. Nine cases of tuberculous mastitis were seen as a distinct mass on mammogram and sonogram. Four of nine cases (44.4%) showed a relatively smooth peripheral margin on mammogram and a cold abscess form on sonogram and CT. There were other foci of tuberculosis in the chest wall, anterior mediastinum, pleural cavity or lung. Five cases demonstrated as a nodular type on US. In the non-tuberculous mastitis group, and abscess with distinct margin or direct contiguity between a breast lesion and the adjacent organ was observed neither on mammogram nor on sonogram. In an afebrile patient, relative homogeneous density with distinct margin in the breast on mammogram and a fistulous connection or direct continuity between breat abscess form with the adjacent organ on sonogram or CT is a characteristic feature of the tuberculous mastitis. The cold abscess type is a frequent subtypes of this entity, and must also be included.

In the non-tuberculous mastitis group, and abscess with distinct margin or direct contiguity between a breast lesion and the adjacent organ was observed neither on mammogram nor on sonogram. In an afebrile patient, relative homogeneous density with distinct margin in the breast on mammogram and a fistulous connection or direct continuity between breat abscess form with the adjacent organ on sonogram or CT is a characteristic feature of the tuberculous mastitis. The cold abscess type is a frequent subtypes of this entity, and must also be included

    Lactoferrin gene is one of the important candidate genes for mastitis resistance. The gene is located on chromosome BTA 22 and consists of 17 exons spanning over 34.5kb of genomic DNA. The present study was undertaken with the objectives to identify allelic variants in exons 7 and 12 of lactoferrin gene and to analyze association between its genetic variants and incidence of clinical mastitis in Murrah buffalo. The amplification of exons 7 and 12 of lactoferrin gene yielded amplicons of 232- and 461-bp sizes. PCR-restriction fragment length polymorphism (RFLP) analysis of 232-bp amplicon using BccI restriction enzyme revealed three genotypes (AA, AB, and BB) with frequencies of 0.62, 0.22, and 0.16, respectively. The frequencies of two alleles, A and B, were estimated as 0.73 and 0.27. Hpy188I-RFLP for 461-bp amplicon revealed polymorphism with three genotypes, CC, CD, and DD, with respective frequencies of 0.06, 0.39, and 0.56, whereas frequencies for C and D alleles were 0.25 and 0.75. The chi-square (?(2)) analysis revealed a significant association between incidence of clinical mastitis and genetic variants of exon 7, and animals of AA genotype of exon 7 were found to be least susceptible to mastitis. The findings indicate potential scope for incorporation of lactoferrin gene in selection and breeding of Murrah buffaloes for improved genetic resistance to mastitis. PMID:25677166

    Full Text Available The aim of this work was to identify and to characterise Staphylococcus aureus isolates associated with subclinical mastitis obtained from milk of lactating cows showing a California Mastitis Test (CMT score result of traces, 1, 2, or 3. Coagulase, hemolysis, presence of capsule, slime formation, biofilm production, autoaggregation, hemagglutination and antibiotic susceptibility were assessed to evaluate S. aureus virulence factors expression potentially associated to bovine subclinical mastitis isolates. Prevalence of subclinical mastitis along the study was low and did not correlate with months or climatic variables. Most of S. aureus (20 were isolated from milk samples showing a CMT score result of 1. Formation of capsule, slime, biofilms and the occurrence of bacteria aggregation in all the tested isolates converged in the bacterial ability of adherence and persistence in the mammary gland and probably contribute to the further chronicity of the infection and even the colonization of dairy installations. Resistance against a set of commonly used antibiotics was low. The evaluation of virulence factors of S. aureus isolates in the context of subclinical mastitis in dairy farms may be useful to develop precise actions and treatments to control mastitis and to improve animal health and milk production in dairy bovine herds.

  10. Norwegian mastitis control programme

    Full Text Available Abstract This paper describes the methods and results of the Norwegian Mastitis Control Program implemented in 1982. The program has formed an integral part of the Norwegian Cattle Health Services (NCHS since 1995. The NCHS also have specific programs for milk fever, ketosis, reproduction and calf diseases. The goal of the program is to improve udder health by keeping the bulk milk somatic cell count (BMSCC low, to reduce the use of antibiotics, to keep the cost of mastitis low at herd level and improve the consumers' attitude to milk products. In 1996, a decision was made to reduce the use of antibiotics in all animal production enterprises in Norway by 25% within five years. Relevant data has been collected through the Norwegian Cattle Herd Recording System (NCHRS; including health records since 1975 and somatic cell count (SCC data since 1980. These data have been integrated within the NCHRS. Since 2000, mastitis laboratory data have also been included in the NCHRS. Data on clinical disease, SCC and mastitis bacteriology have been presented to farmers and advisors in monthly health periodicals since 1996, and on the internet since 2005. In 1996, Norwegian recommendations on the treatment of mastitis were implemented. Optimal milking protocols and milking machine function have been emphasised and less emphasis has been placed on dry cow therapy. A selective dry cow therapy program (SDCTP was implemented in 2006, and is still being implemented in new areas. Research demonstrates that the rate of clinical mastitis could be reduced by 15% after implementing SDCTP. The results so far show a 60% reduction in the clinical treatment of mastitis between 1994 and 2007, a reduction in BMSCC from 250,000 cells/ml to 114,000 cells/ml, and a total reduction in the mastitis cost from 0.23 NOK to 0.13 NOK per litre of milk delivered to the processors, corresponding to a fall from 9.2% to 1.7% of the milk price, respectively. This reduction is attributed to changes in attitude and breeding, eradicating bovine virus diarrhoea virus (BVDV and a better implementation of mastitis prevention programmes.

  11. Mastitis therapy and antimicrobial susceptibility: a multispecies review with a focus on antibiotic treatment of mastitis in dairy cattle.

    2011-12-01

    Mastitis occurs in numerous species. Antimicrobial agents are used for treatment of infectious mastitis in dairy cattle, other livestock, companion animals, and humans. Mastitis is an economically important disease of dairy cattle and most mastitis research has focused on epidemiology and control of bovine mastitis. Antibiotic treatment of clinical and subclinical mastitis in dairy cattle is an established component of mastitis control programs. Research on the treatment of clinical and subclinical mastitis in other dairy species such as sheep and goats has been less frequent, although the general principles of mastitis therapy in small ruminants are similar to those of dairy cattle. Research on treatment of clinical mastitis in humans is limited and as for other species empirical treatment of mastitis appears to be common. While antimicrobial susceptibility testing is recommended to direct treatment decisions in many clinical settings, the use of susceptibility testing for antibiotic selection for mastitis treatments of dairy cattle has been challenged in a number of publications. The principle objective of this review is to summarize the literature evaluating the question, "Does antimicrobial susceptibility predict treatment outcome for intramammary infections caused by common bacterial pathogens?" This review also addresses current issues related to antimicrobial use and treatment decisions for mastitis in dairy cattle. Information on treatment of mastitis in other species, including humans, is included although research appears to be limited. Issues related to study design, gaps in current knowledge and opportunities for future research are identified for bovine mastitis therapy. PMID:21984469

Materials and Methods: Milk and blood cell counts were estimated from 8 healthy, 8 subclinical (SCM, and 8 clinically mastitis (CM groups of Karan Fries (KF cows. Results: Total leucocyte counts and neutrophil percent in blood and milk somatic cells and milk neutrophil percent of healthy cows increased significantly (p<0.05 in SCM cows and CM cows. Viability of blood and milk neutrophils was more in healthy cows, but decreased significantly (p<0.05 in SCM and CM cows. Significant (p<0.05 decrease were also observed in both the blood and milk lymphocytes and monocytes of SCM and CM cows. Phagocytic activity (PA of blood neutrophils also decreased significantly (p<0.05 in SCM cows. There was no difference between the PA of SCM and CM cows. Milk neutrophil percent was more in the SCM and clinically infected milk than in the blood of these cows. About 96-97% of the neutrophils had segmented nucleus in both healthy and subclinical milk, whereas, 2-3% were having band shaped or immature nuclei. There was a significant decrease in the segmented neutrophils, whereas, band neutrophils increase significantly to about 5% in the infected milk of mastitic cows. Viability of the milk neutrophils decreased more in case of subclinical and clinical milk as compared to that of blood. PA was found to be highest in the milk of healthy group of cows, but decreased significantly (p<0.05 in subclinically infected cows. However, there was no difference between the PA of milk neutrophils of SCM and CM cows. PA of milk was also found to be significantly lower in the milk of healthy cows when compared to that of blood neutrophils. Conclusion: This study indicated that percent neutrophils and their type in conjunction with milk somatic cell counts can be used as a more reliable indicator of mammary health in cows.

    Chronic mastitis is a prolonged inflammatory breast disease, and little is known about its etiology. We identified 85 cases and 112 controls from 5 hospitals in Morocco and Egypt. Cases were women with chronic mastitis (including periductal, lobular, granulomatous, lymphocytic, and duct ectasia with mastitis). Controls had benign breast disease, including fibroadenoma, benign phyllodes, and adenosis. Both groups were identified from histopathologically diagnosed patients from 2008 to 2011, frequency-matched on age. Patient interviews elicited demographic, reproductive, breastfeeding, and clinical histories. Cases had higher parity than controls (OR = 1.75, 1.62-1.90) and more reported history of contraception use (OR = 2.73, 2.07-3.61). Cases were less likely to report wearing a bra (OR = 0.56, 0.47-0.67) and less often used both breasts for breastfeeding (OR = 4.40, 3.39-5.72). Chronic mastitis cases were significantly less likely to be employed outside home (OR = 0.71, 0.60-0.84) and more likely to report mice in their households (OR = 1.63, 1.36-1.97). This is the largest case-control study reported to date on risk factors for chronic mastitis. Our study highlights distinct reproductive risk factors for the disease. Future studies should further explore these factors and the possible immunological and susceptibility predisposing conditions. PMID:24327928

  15. Mammographic features of isolated tuberculous mastitis

    International Nuclear Information System (INIS)

    To present the mammography findings in 8 patients with tuberculosis (TB) of the breast, with a review of the literature. This study is a retrospective data collection. Each chart with confirmed breast TB based on bacteriology or pathologic findings was analyzed for clinical presentation, gender, nationality, demographic data, prior history of TB, investigation, management, mammographic findings and ultrasound, when available. Mammograms were reviewed by 2 consultant radiologists without knowing the previous diagnosis or the nature of the study. The study was carried out at The State Tuberculosis Registry and Radiology Department, Hamad General Hospital, State of Qatar, from 1990 to 2002. Out of 13 females with TB mastitis, only 8 cases had mammograms preoperatively. The incidence of breast TB in Qatar is rare (1/1000 mammograms per year). Three types of TB mastitis were identified in our study; the nodular (50%), the diffuse (37.5%) of which 77% were limited to one sector of the breast and the sclerosing (12.5%) mastitis. Three patients (43%) were reported as carcinoma. Although mammography identified 3 types of TB, it was not helpful in differentiating TB from carcinoma of the breast. However, the careful evaluation of the degree of density and trabecular thickening of the mass in relation to it size might reduce the number of false positive cases of carcinoma diagnosed with mammograms. Biopsy specimen remains the best diagnostic tool in TB mastitis. (author)

    Bovine udder infections induce a variety of changes in gene expression of different growth factors that may suggest their possible role in glandular tissue protection or repair processes. Growth factors and also chemokines and cytokines may act synergistically to increase the infiltration of neutrophils and macrophages to promote angiogenesis, fibroplasia, matrix deposition, and, ultimately, re-epithelialization. Considering the vast applications, typically in human medicine, of platelet concentrate (PC) and its ease of preparation, the aim of our study was to evaluate an alternative therapy to stimulate the regeneration of glandular tissue, administering a concentration in excess of the growth factors contained in the PC. In each one of the 3 farms examined in the trial, PC was prepared from donor cows in good health, free from infections, and with no records of medications administered during the previous 2 mo. The platelet produced in one farm was used only for treating the cows of the same farm in a heterologous way. A total of 229 mastitic quarters were divided in 3 groups: antibiotic group (treated with intramammary antibiotic), antibiotic and PC group (treated intramammarily with antibiotics in association with PC), and PC group (treated with intramammary PC alone). The diagnosis of mastitis was based on somatic cell count and bacteriological evaluation of the milk from the affected quarter. Platelet concentrate, alone or in association with antibiotic, was used for 3 consecutive days as an unconventional therapy in bovine acute and chronic mastitis. Our data show that the associated action of antibiotic and PC performed significantly better than the antibiotic alone, either for the recovery of the affected mammary quarters or for somatic cell count reduction. In the same way, the association antibiotic plus PC showed significantly fewer relapses compared with the antibiotic alone, either for acute or chronic mastitis. The treatment with only PC did not show statistically significant differences compared with both antibiotic alone or associated treatment for acute mastitis, and it was better than the use of only antibiotic for chronic mastitis. Our results show that PC alone may be useful for a quick resolution of the inflammatory response, playing a role in limiting the tissue damage to the mammary gland parenchyma and reducing the recurrence rates.

    Biopsy by fine needle aspiration together with microbiological examination and scanning electron microscopy were evaluated in diagnosis of clinical bovine mastitis in a Prototheca zopfii outbreak. Fine needle aspiration was performed in 21 mammary quarters from ten Holstein cows presenting clinical mastitis caused by P. zopfii. The algae were previously identified in the microbiological examination of milk collected from these cows. Material aspirated from these 21 mammary glands was submitted to cytological staining (Gram, Giemsa and/or Shor staining). Fine needle aspiration enabled cytological identification of the algae in these 21 mammary glands, from which P. zopfii was isolated in the milk. Simultaneously, five mammary fragments collected by fine needle aspiration from these 21 mammary glands presenting clinical mastitis were also submitted to microbiological examination. P. zopfii was also isolated from these five fragments. Scanning electron microscopy technique also identified three of these five P zopfii strains isolated from mammary fragments collected by cytological aspiration. These results suggest that fine needle aspiration may be an alternative method for the diagnosis of clinical mastitis. PMID:15487325

    The aims of this study were to estimate the incidence rate of clinical mastitis (IRCM) and identify risk factors for clinical mastitis in suckler ewes to generate hypotheses for future study. A postal questionnaire was sent to 999 randomly selected English sheep farmers in 2010 to gather data on farmer reported IRCM and flock management practices for the calendar year 2009, of which 329 provided usable information. The mean IRCM per flock was 1.2/100 ewes/year (CI:1.10:1.35). The IRCM was 2.0, 0.9 and 1.3/100 ewes/year for flocks that lambed indoors, outdoors and a combination of both, respectively. Farmers ran a variety of managements before, during and after lambing that were not comparable within one model, therefore six mixed effects over-dispersed Poisson regression models were developed. Factors significantly associated with increased IRCM were increasing percentage of the flock with poor udder conformation, increasing mean number of lambs reared/ewe and when some or all ewes lambed in barns compared with outdoors (Model 1). For ewes housed in barns before lambing (Model 2), concrete, earth and other materials were associated with an increase in IRCM compared with hardcore floors (an aggregate of broken bricks and stones). For ewes in barns during lambing (Model 3), an increase in IRCM was associated with concrete compared with hardcore flooring and where bedding was stored covered outdoors or in a building compared with bedding stored outdoors uncovered. For ewes in barns after lambing (Model 4), increased IRCM was associated with earth compared with hardcore floors, and when fresh bedding was added once per week compared with at a frequency of ≤2 days or twice/week. The IRCM was lower for flocks where some or all ewes remained in the same fields before, during and after lambing compared with flocks that did not (Model 5). Where ewes and lambs were turned outdoors after lambing (Model 6), the IRCM increased as the age of the oldest lambs at turnout increased. We conclude that the reported IRCM is low but highly variable and that the complexity of management of sheep around lambing limits the insight into generating hypotheses at flock level for risks for clinical mastitis across the whole industry. Whilst indoor production was generally associated with an increased IRCM, for ewes with large litter size indoor lambing was protective, we hypothesise that this is possibly because of better nutrition or reduced exposure to poor weather and factors associated with hygiene.

    Bovine mastitis is an important and complex disease responsible for economic losses in the dairy industry. Biotype II strains of the green alga Prototheca zopfii can be involved, most often resulting in chronic mastitis of difficult treatment associated with reduced milk production. This type of infection is rare, but the number of reported cases is increasing worldwide. In order to determine the kind of species involved in mastitis by Prototheca in northwest Portugal, 41 Prototheca isolates were genetically characterized. The algae are part of Prototheca isolates that were collected during a 6-year period, isolated from the milk of 41 dairy cows in a total of 22 herds with a history of increasing somatic cell counts, mild clinical signs of udder infection, and unsuccessful response to the usual therapy. PCR amplification of the 18S ribosomal DNA (rDNA), amplified rDNA restriction analysis, and phylogenetic analyses of the 18S rDNA sequences were performed. Thirty-seven isolates were identified as P. zopfii var. hydrocarbonea and four as Prototheca blaschkeae. These data suggest a high incidence of P. zopfii var. hydrocarbonea mastitis in the region and demonstrate for the first time the involvement of P. blaschkeae with bovine mammary gland infections.

    Dairy farmers using automatic milking are able to manage mastitis successfully with the help of mastitis attention lists. These attention lists are generated with mastitis detection models that make use of sensor data obtained throughout each quarter milking. The models tend to be limited to using the maximum or average value of the sensor data pattern, potentially excluding other valuable information. They often put cows on the lists unnecessarily, and their sensitivity for abnormal milk cla...

    Full Text Available Abstract Background In Denmark, it has recently become mandatory for all dairy farmers with more than 100 cows to sign up for a herd health programme. Three herd health programmes are available. These differ in a number of aspects, including the frequency of veterinary visits and the farmer’s access to prescription drugs. The objective of this study was to investigate whether dairy farmers’ behavioural intentions, i.e. to call a veterinarian or start medical treatment on the day that they detect a cow with mild clinical mastitis (MCM, are different depending on the type of herd health programme. Methods A questionnaire survey based on the Theory of Planned Behaviour (TPB was conducted. TPB proposes that a person’s behavioural intention is strongly correlated with his or her actual behaviour. Three behavioural factors determine the behavioural intention: attitude, subjective norm and perceived behavioural control. Each of these factors is decided by a set of beliefs, each of which in turn is weighted by an evaluation: 1 the expected outcomes of performing the behaviour, 2 what a person believes that others think of the behaviour, and 3 the person’s perceived power to influence the behaviour. A set of statements about the treatment of MCM based on interviews with 38 dairy farmers were identified initially. The statements were rephrased as questions and the resulting questionnaire was distributed to 400 randomly selected Danish dairy farmers who use the two most restrictive herd health programmes, either Core or Module1, and to all 669 farmers with the least restrictive herd health programme, Module2. The association between intention and the herd health programme was modelled using logistic regression. Results The farmers with the Module2 herd health programme had a significantly higher behavioural intention to perform the behaviour, when compared to farmers with a more restrictive herd health programme (OR = 2.1, p Conclusion Danish dairy farmers who participate in Module2 herd health programme had a higher intention to treat cases of MCM, compared to farmers who participate in a more restrictive herd health programme in which the veterinarian initiates treatments.

    IgG4-related orbital disease is a recognised cause for orbital inflammation. As its awareness increases and diagnostic accuracy improves there will be an increased number of cases being identified. This unique case demonstrates for the first time, with histological evidence, a case of a non-lacrimal IgG4-related orbital disease with concurrent IgG4-related mastitis. We describe a 47 year old who presented with a supraorbital swelling and mass. This was initially successfully treated with oral steroids and was later excised on recurrence. Immunohistochemical and blood serum analysis confirmed IgG4-related orbital disease. On systemic enquiry she was found to have a mass of the breast, which was shown to be IgG4-related mastitis. She is currently asymptomatic with no sign of recurrence and is under long-term surveillance. This case highlights the importance of systemic work up in patients presenting with orbital foci of IgG4 disease. PMID:26700191

    Mastitis is defined as an inflammatory reaction of udder tissue to bacterial, chemical, thermal or mechanical injury, which causes heavy financial losses and milk wastage throughout the world. Until now, studies have focused on the economic aspects from which perspective mastitis can generally be considered as the most serious disease in dairy cows; however, costs are not the only negative consequence resulting from the infection. The environmental impact is also significant; milk is discarded, which means lower efficiency and hence a greater environmental impact per produced liter of milk. Less milk is produced, which leads to an increased need for calf feed, and meat production is also affected. The main aim of this paper was to quantify the environmental impact of mastitis incidence. A standard scenario (representative of present-day reality in Galicia, Spain) and an improved scenario (in which mastitis incidence rate is reduced by diverse actions) have been defined and compared using Life Cycle Assessment (LCA) methodology. Among the impact categories studied, acidification, eutrophication and global warming were found to be the most significant environmental impacts. In all these categories, it was revealed that a decrease in mastitis incidence has a positive influence as the environmental impact is reduced. Even if the quantitative results cannot show a considerable decrease in the environmental burden, the impact cannot be regarded as negligible when the total consumption or total production of a region is considered. For example, the outcome of the proposed improvement measures for Spain's greenhouse gas emissions can be quantified as 0.06% of total emissions and 0.56% of emissions by the agricultural sector.

    Full Text Available Mastitis in cows represents one of the most actual problems in intensive dairy production. The prevention of pathogen penetration in the udder, its colonization and reproduction impose the constant need for regular milk check-ups, and preventive and therapeutic measures. Staphylococcus aureus causes subclinical and clinical mastitis, which when in the acute form can originate difficult and malignant udder infections with granulomatous and necrotic changes. Chronic forms of Staphylococcal mastitis most often pass as subclinical cases. An efficient commercial vaccine has not been introduced yet, though the application of autochthonous vaccines in the prevention of mastitis can give satisfactory results. In this study we have developed and applied an autochthonous vaccine prepared from S. aureus isolated from milk samples taken from an experimental farm, as well as from the referent capsular strain S. aureus. The vaccine was applied to experimental dairy cattle twice before calving in a dose of 5 mL. It consisted of inactivated bacterial S. aureus JR3 cells in a quantity of 1x1010 cfu/mL and 5 mg SM capsule of the strain S. aureus 2286. This vaccination of dairy cows has resulted in a significant decrease of subclinical and clinical manifested mastitis in the treated group, when compared to the vaccinated group of experimental animals. .

Abstract in english Mastitis in cattle is a disease that affects the quality and quantity of milk, having a direct impact on public health. Many treatments have been used to reduce inflammation and infection caused by this problem. However, the use of almost all drugs needs a withdrawal time. Using herbal extracts with [...] reported antibacterial capacity, were used against three common mastitis-causing bacteria, Staphylococcus aureus, Streptococcus agalactiae and Escherichia coli. Extracts of Thymus vulgaris, Calendula officinalis and Salvia officinalis were evaluated. In vitro findings revealed bactericidal effect in all dilutions of C. officinalis ½, ¼ and 1:8, as compared with the bactericidal effect of other extracts in the first two dilutions. Control group using propylene glycol demonstrated lower bactericidal effect. Based on these in vitro effects minimization of somatic cell count in bovine mastitis was attempted. The results in the treated groups were of an average of 23% cure rate of infected quarters. Adverse reactions were obtained in 60% of treated quarters. With the above it was conclude that the behavior of the extracts in vitro and in vivo is different. Adverse reactions to the mixture of extracts apparently were not due to the vehicle, taking into account that propylene glycol is a common vehicle for topical and parenteral pharmaceutical preparations.

    Full Text Available In Colombia, the great diversity in management, methods of milking and breeds for milk production, makes very difficult to unify the rules for mastitis control; therefore the veterinarian’s job, according to the available resources in each herd is to advise the best procedures for both, milking routines and mastitis control. Influenced by the differences in management, the prevalence of each of the microorganisms that may cause mastitis varies from region to region and even from herd to herd within the same area. As a rule of thumb, the more basic the system, the less practices for mastitis control are present; this situation consequently leads to a high presentation of contagious mastitis by Streptococcus agalactiae. As the management improves, and dry cow therapy practices are implemented particularly in systems with milking machines, the mayor pathogen isolated is Staphylococcus aureus which is a regular resident in the skin. The number of cases caused by environmental microorganisms is very low, but maintains the clinical level of serious acute mastitis reported in dairy herds in other countries. Due to the indiscriminate and sometimes inappropriate use of antibiotics used for mastitis treatment, a high level of resistance to antibiotics has resulted to most of the antibiotics already in the market. It is imperative a close cooperation between the organizations for drug regulation and control, the pharmaceutical industry and the Veterinary medical profession to established rules and standards to safeguard this non-renewable resource.La diversidad en los sistemas de manejo, métodos de ordeño y aun de razas que se tienen en la producción de leche en Colombia, no permiten unificar las normas para el control de mastitis y será el veterinario quien, de acuerdo con los recursos disponibles en cada finca, establezca los procedimientos para el manejo del ordeño y el control de la mastitis. Influenciados por las diferencias de manejo, la prevalencia de cada uno de los microorganismos causantes de mastitis varía de región a región y aun de finca a finca en la misma zona. Como criterio general, entre más elemental sea el sistema de manejo o menos prácticas en el control de mastitis, predominan las mastitis contagiosas por Streptococcus agalactiae que van cediendo espacio a las producidas por Staphylococcus aureus cuando se implementan las prácticas de terapia de vaca seca, y en los hatos con ordeños mecánicos aumentan los casos por microorganismos localizados en la piel de los pezones. El número de casos por microorganismos ambientales es muy bajo, pero mantiene el comportamiento clínico de mastitis aguda grave que se reporta en los hatos estabulados en otros países. Por el uso indiscriminado y a veces inadecuado que caracteriza el manejo de los antibióticos para el tratamiento de mastitis se tiene un alto nivel de resistencia a la mayoría de los antibióticos existentes en el mercado para el tratamiento de la mastitis. Es urgente que en forma concertada entre el ente de control, la industria farmacéutica y el cuerpo médico veterinario se establezcan normas y criterios para salvaguardar este recurso no renovable.

    Protothecal mastitis, caused mostly by Prototheca zopfii (P. zopfii), is increasing in dairy herds and is being reported globally. The present study was aimed at studying the epidemiology of mastitis and at molecular characterization of P. zopfii isolates from dairy herds and their surroundings in three provinces of China using microbiological, biochemical and molecular methods, and antibiotic susceptibility tests. Samples from milk (n = 620) of mastitic cows and their barns sources (n = 410) including feces, feed, bedding materials and drinking water were analyzed. Among other pathogens recovered from mastitic milk, 84 (13.5 %) of the isolates were identified as P. zopfii. All of the P. zopfii isolates recovered from milk were recognized as genotype 2, whereas 58 (73.4 %) and 21 (26.6 %) isolates from environmental sources were found to be P. zopfii genotypes 1 and 2, respectively. The isolates were susceptible to some antibiotics and antifungal agents, including amikacin (78.1 %), streptomycin (58.5 %), gentamicin (17.8 %), amphotericin B (68.6 %) and nystatin (64.4 %). Additionally, the two genotypes displayed versatile patterns of susceptibility to different antimicrobials agents. Phylogeny of the genotypes on the basis of 18S SSU rDNA and 28S SSU rDNA was also investigated. The isolates of the two genotypes separated into different clades, and no interrelationship was observed among these as shown by phylogenetic analysis. The genotype 1 isolates from cow barn sources were non-pathogenic and may not present any risk of mastitis. We conclude that P. zopfii genotype 2 might play an important role in bovine mastitis in China. PMID:26450620

    This study aims to evaluate the use of an infrared thermograph for mastitis diagnosis in sheep. Thirty-seven Santa Inês ewes were evaluated weekly through infrared images obtained with thermograph FLIR System Series-i®. Milk was collected for somatic cell count and milk compound level determination. The clinical mastitis group had the highest fat and protein level, as well as the lowest lactose level. The udder temperatures were higher for subclinical mastitis group. The udder temperature data was able to correctly classify the animals into the mastitis groups and the canonical analysis showed that these temperatures clearly differentiated the subclinical mastitis groups from the others. Therefore, this study showed that udder infrared temperatures can be used as diagnostic method to mastitis in sheep. PMID:23178047

However, mammography combined with ultrasound examination may lead to the correct diagnosis. In the mammogram a poorly marginated area of increased density can be seen, in case of an abscess there is a more circumscribed lesion. On ultrasound examination there is a well-circumscribed or ill-defined echo-poor lesion. The through transmission is not descreased and septa are frequently observed. If the radiological features correlate with the results of aspiration and cytological examination, the diagnosis NPM can be made and surgical intervention can be avoided.

    Treatment of bovine mastitis depends on the cause, the clinical manifestation and the antibiotic susceptibility of the agent. Mastitis therapy is commonly unsuccessful owing to pathological changes that occur in the udder parenchyma as a result of the inflammatory reaction to mastitogenic bacteria, pharmacokinetic properties of antimicrobial mastitis drugs, mastitogenic bacterial and related factors, and poor animal husbandry and veterinary interventions.

    Aim: Present study aimed to evaluate the different episodes of clinical mastitis (CM) and influence of duration of treatment and seasonality on the occurrence of different episodes of CM in crossbred cows. Materials and Methods: A total of 1194 lactation data of crossbred CM cows were collected from mastitis treatment record from 2002 to 2012. Data of CM cows were classified into types of episodes (pattern of repeated or multiple episodes occurrence) and number of episodes (magnitude of multiple cases). Types of episodes were divided as single (clinical cure by a single episode of treatment), relapse (retreatment of the same cow within 21 days), recurrence (new CM at least 21 days after treatment), and both (relapse and recurrence). The season was classified as winter (December to March), summer (April to June), rainy (July to September), and autumn (October to November). The difference between incidences of different types of CM episodes and the association between number or type of CM episodes with duration of treatment and seasons of CM occurrence were analyzed by Chi-square test. Results: Among 1194 animals suffered with CM, 53, 16, and 18% had the single episode, relapse, and recurrence, respectively; while 13% suffered by both relapse and recurrence. We estimated the duration of treatment and found 80% of the cows treated 1-8 days, in which 65% treated for 1-4 days, while 35% cows were treated for 5-8 days. Further, 12% cows treated for 9-15 days and 7.5% cows treated >15 days. The relationship between duration of treatment and different episodes of CM revealed that 1-8 days treated cows were mostly cured by the single episode with less relapse and recurrence. In contrast, the incidences of recurrence and relapse episodes were higher in cows treated for more than 9 days. The highest incidence of relapse was noticed in winter (36%) than other seasons (10-28%), while the recurrence was less during autumn (9%) compared to other seasons (20-40%). Conclusion: Cows those suffered by both relapse and recurrence were more susceptible to CM, and they need to be culled from farm to control the transmission of infections. Although the influence of seasonality was difficult to understand, the higher magnitude of relapse and recurrence during winter suggested the adverse effects of cold stress on treatment outcome.

Results: Among 1194 animals suffered with CM, 53, 16, and 18% had the single episode, relapse, and recurrence, respectively; while 13% suffered by both relapse and recurrence. We estimated the duration of treatment and found 80% of the cows treated 1-8 days, in which 65% treated for 1-4 days, while 35% cows were treated for 5-8 days. Further, 12% cows treated for 9-15 days and 7.5% cows treated >15 days. The relationship between duration of treatment and different episodes of CM revealed that 1-8 days treated cows were mostly cured by the single episode with less relapse and recurrence. In contrast, the incidences of recurrence and relapse episodes were higher in cows treated for more than 9 days. The highest incidence of relapse was noticed in winter (36% than other seasons (10-28%, while the recurrence was less during autumn (9% compared to other seasons (20-40%. Conclusion: Cows those suffered by both relapse and recurrence were more susceptible to CM, and they need to be culled from farm to control the transmission of infections. Although the influence of seasonality was difficult to understand, the higher magnitude of relapse and recurrence during winter suggested the adverse effects of cold stress on treatment outcome.

    Full Text Available Abstract Background Sub-clinical mastitis limits milk production and represents an important barrier to profitable livestock economics worldwide. Milk production from cows in Nigeria is not at optimum levels in view of many factors including sub-clinical mastitis. Results The overall herd-level prevalence rate for SCM was 85.33% (256/300 heads of cows while the quarter-level prevalence rate of SCM was 43.25% (519/1,200 quarters. The prevalence of SCM was 50.67%, 43.67%, 39.67% and 39.13% for the left fore-quarter, right hind-quarter, left hind-quarter and right fore-quarter, respectively. The Rahaji breed had the highest prevalence of SCM with 65.91% (29/44, while the White Fulani breed had the least with 32.39% (57/176. A total of 32.33% (97/300 had only one mammary quarter affected, 30.33% (91/300 had two quarters affected, 16.00% (48/300 had three quarters affected while 6.67% (20/300 had all the four quarters affected. A total of 53.00% had SCM in multiple quarters (159/300. The risk of SCM decreased significantly among young lactating cows compared to older animals (OR = 0.283; P P = 0.013; 95% CI = 1.557; 43.226. Improved sanitation (washing hands before milking will decrease the risk of SCM (OR = 0.173; P = 0.003; 95% CI = 0.054; 0.554. Conclusion SCM is prevalent among lactating cows in the Nigerian Savannah; and this is associated with both animal characteristics (age, breed and individual milk quarters and milking practices (hand washing.Good knowledge of the environment and careful management of the identified risk factors with improved sanitation should assist farm managers and veterinarians in implementing preventative programmes to reduce the incidence of SCM.

    Full Text Available Tubercular mastitis is a rare clinical entity as mammary gland tissue, like spleen and skeletal muscle, offers resistance to the survival and multiplication of the tubercle bacillus. Tuberculosis of the breast can mimic carcinoma, whereas in young patients it can be mistaken for a pyogenic breast abscess, thus labeled a great masquerader in recognition of its multifaceted presentation. Breast tuberculosis commonly affects women in the reproductive age group, between 21 and 30 years, and is rare in prepubescent females and elderly women. Fine needle aspiration cytology is very useful and it is a promising technique in expert hands. In tuberculosis-endemic countries, the finding of granuloma on fine needle aspiration cytology warrants empirical treatment for tuberculosis even in the absence of positive acid-fast bacilli and without culture results. We hereby report a case of tubercular mastitis in a post-menopausal seronegative female diagnosed on fine needle aspiration cytology with a positive acid-fast bacilli and a review of the recent literature.

    2012-12-28

    Trueperella pyogenes, recently reclassified from the genus Arcanobacterium, is considered the causative agent of acute suppurative mastitis called summer mastitis. T. pyogenes produces a variety of known and putative virulence factors that include pyolysin and factors promoting adhesion to host cells. The objective of this study was to report the presence of virulence genes in T. pyogenes isolates that were identified as etiological agents of clinical mastitis in cows, as well as to determine antimicrobial resistance and distribution of selected determinants that can be associated with phenotypic resistance among these isolates. The presence of genes (plo, nanH, nanP, cbpA, fimA, fimC, fimE, fimG, tet(W), erm(X), erm(B)) was examined by conventional PCRs. Resistance to 10 antimicrobial agents was determined by the broth microdilution method. Among T. pyogenes isolates of bovine mastitis origin the genes encoding all virulence factors occurred. Besides pyolysin gene plo, the fimA was the only gene detected in all isolates, whereas other virulence factor genes were found with different frequencies. Phenotypic antimicrobial resistance was observed to tetracycline (85.5% isolates) and erythromycin (9.1%). Isolates non-susceptible to erythromycin simultaneously exhibited increased MIC of pirlimycin. Beta-lactams were active against isolates. We found the correlation between the presence of tetracycline and macrolide resistance genes and corresponding resistance phenotype. Genotypic characterization of a large number of T. pyogenes isolates from different herds performed in this study may be useful in explanation, which virulence factors play a significant role in the establishment of bovine mammary gland infection.

    Full Text Available This study was carried out to determine the prevalence of coagulase-negative staphylococci in clinical and subclinical mastitis in commercial and small-scale farms in Zimbabwe. Thirty five quarter milk samples from clinical mastitis cases and 371 quarter milk samples from cows with subclinical mastitis were cultured for bacterial pathogens. The most frequent pathogens isolated in clinical mastitis were the enteric bacteria (31.4 %, followed by coagulase negative staphylococci (22.9 % and then Staphylococcus aureus (17.1 %, whereas in subclinical mastitis S. aureus (34.2 % and coagulase-negative staphylococci were (33.2 % the most common. Bacillus species were only isolated in milk samples from subclinical mastitis. Coagulase-negative staphylococci were observed in mixed infections with other bacteria in only 2.2 % of the 406 milk samples from clinical and subclinical mastitis where they were isolated together with Bacillus species in 6 of the 9 mixed infection cases. About 95 % of the milk samples from which 131 coagulase-negative staphylococci were isolated had correspondingly high somatic cell counts. The coagulase-negative staphylococci isolated most frequently were S. chromogenes (7.9 %, S. epidermidis (7.4 % and S. hominis (5.9 %. They were all associated with high somatic cell counts. All the coagulase-negative staphylococci isolates were susceptible to cloxacillin and erythromycin, and more than 90 %of the isolates were susceptible to neomycin, penicillin and streptomycin. The highest resistance was to tetracycline (17.6 %, followed by lincomycin (13.7 %. About 8 % of the isolates were resistant to both penicillin and streptomycin.

    Mastitis is an inflammation of the udder caused by bacteria that invade the udder through the teat canal, causing either persistent intramammary infections, or short, transient infections. Mastitis is the most costly disease on a dairy farm because it directly affects the production of milk, the primary source of income for the dairy farmer. Mastitis can be visible (clinical mastitis) or invisible (subclinical mastitis). A large proportion of farmers repeats antibiotic treatment after initial...

    Mastitis is an important animal health disease which constitutes a serious problem for the dairy industry in New Zealand. Mastitis reduces milk yield and quality, necessitates the use of antibiotic therapy, with associated risks of contaminating the raw milk supply, and imposes a serious economic burden, currently estimated at NZ$300 million per year. Mastitis is caused by a variety of infectious agents. In the New Zealand context, with cattle grazing on pasture, Streptococcus uberis is a major bacterial pathogen, responsible for a significant proportion of clinical cases, especially during early lactation and the dry period. Other pathogens of significance include Staphylococcus aureus, Streptococcus dysgalactiae and Escherichia coli, as well as so-called 'minor pathogens', namely coagulase-negative staphylococci(CNS). Current strategies aimed at reducing cases of mastitis include improved hygiene in the farm environment, particularly with regards to the health and cleanliness of teats. Once mastitis occurs, antibiotic therapy is a favoured option, and as a prophylactic tool, in the form of dry-cow therapy, has also shown value. Prevention of mastitis using immunological tools such as vaccines lags behind the major vaccine breakthroughs that have been achieved in preventing and/or reducing the severity of numerous infectious diseases in animals. In this review, the current state of research in the area of development of vaccines against mastitis is summarised, with particular emphasis on bacteria important to the dairy farming industry in New Zealand. Few, if any, effective vaccines have been designed to prevent or mitigate intramammary infections. It is argued that novel approaches must be considered to search for vaccine candidates, and vaccines need to be designed and constructed within the special framework of their uses, in the mammary gland which offers a unique immunological environment. In addition, effective vaccines against mastitis due to Strep. uberis may be more likely to emerge from strategies that target the cell-mediated arm of the immune response rather than strategies that target specific antibody responses.

  3. Granulomatous mastitis: radiological findings

    International Nuclear Information System (INIS)

    Purpose: To evaluate the radiological, ultrasonographic, and magnetic resonance imaging (MRI) findings of idiopathic granulomatous mastitis. Material and Methods: Between April 2002 and June 2005, the mammography, ultrasound, color Doppler ultrasound, non enhanced MR, and dynamic MR findings of nine patients with the preliminary clinical diagnosis of malignancy and the final diagnosis of granulomatous mastitis were evaluated. Results: On mammography, asymmetrical focal densities with no distinct margins, ill-defined masses with spiculated contours, and bilateral multiple ill-defined nodules were seen. On ultrasound, in four patients a discrete, heterogenous hypoechoic mass, in two patients multiple abscesses, in one patient bilateral multiple central hypo peripheral hyperechoic lesions, in two patients heterogeneous hypo- and hyperechoic areas together with parenchymal distortion, and in one patient irregular hypoechoic masses with tubular extensions and abscess cavities were seen. Five of the lesions were vascular on color Doppler ultrasound. On MR mammography, the most frequent finding was focal or diffuse asymmetrical signal intensity changes that were hypointense on T1W images and hyperintense on T2W images, without significant mass effect. Nodular lesions were also seen. On dynamic contrast-enhanced mammography, mass-like enhancement, ring-like enhancement, and nodular enhancement were seen. The time-intensity curves differed from patient to patient and from lesion to lesion. Conclusion: The imaging findings of idiopathic granulomatous mastitis have a wide spectrum, and they are inconclusive for differentiating malignant and benign lesions

    2011-01-01

    Background A nationwide survey on the microbial etiology of cases of subclinical mastitis in dairy cows was carried out on dairy farms in Sweden. The aim was to investigate the microbial panorama and the occurrence of antimicrobial resistance. Moreover, differences between newly infected cows and chronically infected cows were investigated. Methods In total, 583 quarter milk samples were collected from 583 dairy cows at 226 dairy farms from February 2008 to February 2009. The quarter milk samples were bacteriological investigated and scored using the California Mastitis Test. Staphylococci were tested for betalactamase production and presence of resistance was evaluated in all specific udder pathogens. Differences between newly infected cows and chronically infected cows were statistically investigated using logistic regression analysis. Results The most common isolates of 590 bacteriological diagnoses were Staphylococcus (S) aureus (19%) and coagulase-negative staphylococci (CNS; 16%) followed by Streptococcus (Str) dysgalactiae (9%), Str. uberis (8%), Escherichia (E.) coli (2.9%), and Streptococcus spp. (1.9%). Samples with no growth or contamination constituted 22% and 18% of the diagnoses, respectively. The distribution of the most commonly isolated bacteria considering only bacteriological positive samples were: S. aureus - 31%, CNS - 27%, Str. dysgalactiae - 15%, Str. uberis - 14%, E. coli - 4.8%, and Streptococcus spp. - 3.1%. There was an increased risk of finding S. aureus, Str. uberis or Str. dysgalactiae in milk samples from chronically infected cows compared to findings in milk samples from newly infected cows. Four percent of the S. aureus isolates and 35% of the CNS isolates were resistant to penicillin G. Overall, resistance to other antimicrobials than penicillin G was uncommon. Conclusions Staphylococcus aureus and CNS were the most frequently isolated pathogens and resistance to antimicrobials was rare. PMID:21649936

    Full Text Available Abstract Background Lactational mastitis is a painful, debilitating condition that if inappropriately managed, may lead women to discontinue breastfeeding prematurely. The aim of this paper is to report the incidence of mastitis in the first six months postpartum in a Scottish population, its impact on breastfeeding duration and to describe the type and appropriateness of the support and management received by affected women from health professionals. Methods A longitudinal study of 420 breastfeeding women was undertaken in Glasgow in 2004/05. Participants were recruited and completed a baseline questionnaire before discharge from hospital. Cases of mastitis were reported either directly to the researchers or were detected during regular follow-up telephone interviews at weeks 3, 8, 18 and 26. Women experiencing mastitis provided further information of their symptoms and the management and advice they received from health professionals. Results In total, 74 women (18% experienced at least one episode of mastitis. More than one half of initial episodes (53% occurred within the first four weeks postpartum. One in ten women (6/57 were inappropriately advised to either stop breastfeeding from the affected breast or to discontinue breastfeeding altogether. Conclusion Approximately one in six women is likely to experience one or more episodes of mastitis whilst breastfeeding. A small but clinically important proportion of women continue to receive inappropriate management advice from health professionals which, if followed, could lead them to unnecessarily deprive their infants prematurely of the known nutritional and immunological benefits of breast milk.

This study included 19 patients (age range: 22 to 56 years; mean 37 years) with 22 lesions that were pathologically confirmed as having granulomatous mastitis. All the patients underwent a breast ultrasonography and 13 patients underwent a mammography. The results of the mammography revealed focal asymmetry (n = 9), multiple ill-defined isodense nodules (n 2), ill-defined nodular density on craniocaudal view (n = 1), and unremarkable finding (n = 1). The sonographic findings included continuous or discontinuous multiple tubular and nodular low echoic lesions (n = 7), ill-defined heterogeneously low echoic lesion (n = 5), irregular-shaped, ill-defined low echoic mass (n = 4), fluid collection with internal floating materials suggesting the presence of an abscess (n = 4), ill-defined heterogeneously low echoic lesion and abscess (n = 1), and multiple ill-defined nodules (n = 1). In the case of granulomatous mastitis, the mammography results indicate a lack of specificity between normal findings and focal asymmetry. The sonographic findings indicate that ill-defined heterogeneously low echoic lesions or irregular shaped, ill-defined low echoic masses are difficult to differentiate from breast cancer. The sonographic findings of abscesses indicate a difficulty in differentiating them from cases of pyogenic mastitis. However, multiple tubular and nodular low echoic lesions, especially with a continuous appearance, should point to granulomatous mastitis, and is helpful in its differential diagnosis and treatment

  12. [Occurrence of Prototheca mastitis in dairy farms in Hesse].

    Schlenstedt, R; Zschck, M; Kloppert, B; Wolter, W

    1997-08-01

    During January 1994 and August 1996 from dairy farms in Hessia a total of 305,609 milk samples were investigated. Prototheca sp. as etiological agent of a mastitis was isolated from milk samples of seven dairy herds. According to our experiences and to several reports from various countries dealing with Prototheca infections in dairy herds, mastitis control programs should include Prototheca algae as potential pathogens. Mastitis due to this organism usually occurs in different semeiologies, one with clinical symptoms, and the other, more common type, as subclinical mastitis. In both cases, Prototheca organisms use to persist in the tissue of the mammary gland also during the dry period and antimicrobial treatment proves to be ineffective. Considering the wide distribution of these algae as saprophytes in the environment and in feces of several domestic animals, predisposing factors like a humid aerobic milieu and unsanitary milking conditions are necessary for Prototheca infections becoming manifest in the udder of dairy cows. Control measures should preferably stress the identification and removal of infected animals, in particular when the disease is sporadic in the herd. Due to the more questionable occurrence of spontaneous healing and the lack of an efficient drug, slaughtering of infected cows appears as a suitable method to eliminate the disease from the herd. Additionally, improvement of the hygiene status concerning feeding and milking management within a herd is as essential as in the control of other opportunistic udder pathogens. PMID:9441042

This report describes 2 cases attributable to these bacteria that resulted in extramammary involvement and augmented morbidity. Cases: Two cases of postpartum mastitis are described, one leading to necrotizing fasciitis caused by group A streptococci and the other leading to toxic shock syndrome (TSS) caused by S. aureus. Conclusion: ...

  14. Idiopathic granulomatous mastitis

    International Nuclear Information System (INIS)

    Objective was to discuss the clinical and radiological features and treatment approaches in 14 patients diagnosed with idiopathic granulomatous mastitis (GM). We retrospectively evaluated the clinical features, radiological findings and treatment approaches in 14 patients with idiopathic GM in the General Surgery Department, Gulhane School of Medicine, Ankara, Turkey between April 2000 and June 2006. The mean age of the patients was 34.5 years (range 27-41 years). The complaints at admission were a mass in the breast in 7 (50%) patients, an abscess and a mass in 6 (42.8%) and a skin fisculain one (7.2%). Granulomatous mastitis was unilateral in all subjects (on the right in 5 patients and on the left in 9). All of the patients underwent ultrasonographic evaluation. Mammography was performed in 8 and magnetic resonance imaging in 5 patients. Seven patients (50%) were suspected to have breast carcinoma according radiological findings. We performed the large excision in 11, incisional biopsy plus abscess drainage in one, and incisional biopsy plus abscess drainage plus medical treatment (prednisolone, methotrexate) in 2 patients. Due to the development of abscess after 9 months, drainage and large excision were performed in one patient who received medical treatment. Idiopathic GM is a disease that generally affects young women of reproductive age and may be mistaken for breast carcinoma in clinical and radiological evaluations. The gold standard for the diagnosis is histopathologic evaluation. (author)

    Escherichia coli, one of the main causative agents of bovine mastitis, is responsible for significant losses on dairy farms. In order to better understand the pathogenicity of E. coli mastitis, an accurate characterization of E. coli strains isolated from mastitis cases is required. By using phylogenetic analyses and whole genome comparison of 5 currently available mastitis E. coli genome sequences, we searched for genotypic traits specific for mastitis isolates. Our data confirm that there is a bias in the distribution of mastitis isolates in the different phylogenetic groups of the E. coli species, with the majority of strains belonging to phylogenetic groups A and B1. An interesting feature is that clustering of strains based on their accessory genome is very similar to that obtained using the core genome. This finding illustrates the fact that phenotypic properties of strains from different phylogroups are likely to be different. As a consequence, it is possible that different strategies could be used by mastitis isolates of different phylogroups to trigger mastitis. Our results indicate that mastitis E. coli isolates analyzed in this study carry very few of the virulence genes described in other pathogenic E. coli strains. A more detailed analysis of the presence/absence of genes involved in LPS synthesis, iron acquisition and type 6 secretion systems did not uncover specific properties of mastitis isolates. Altogether, these results indicate that mastitis E. coli isolates are rather characterized by a lack of bona fide currently described virulence genes. PMID:26809117

  2. Mastitis prevention and control practices and mastitis treatment strategies associated with the consumption of (critically important) antimicrobials on dairy herds in Flanders, Belgium.

    2016-04-01

    The main objectives of this study were to evaluate to what extent variations in herd-level antimicrobial consumption (AMC) can be explained by differences in management practices that are consistently effective in the prevention of (sub)clinical mastitis, on the one hand, and by differences in mastitis treatment strategies, on the other hand. Antimicrobial consumption data were obtained during 2012 and 2013 by "garbage can audits" and expressed as antimicrobial treatment incidences (ATI) for all compounds combined (total ATI) and for the critically important antimicrobials for human health separately. Data on mastitis prevention and control practices were obtained via face-to-face interviews performed during herd visits in March 2013. Some management practices and treatment strategies related to udder health were associated with the total AMC. However, the results demonstrated that implementing effective udder health management practices does not necessarily imply a low AMC and vice versa. Herds participating in a veterinary herd health management program and herds selectively drying off cows used fewer antimicrobials compared with herds not participating in such a program or applying blanket dry-cow therapy. Moreover, herds treating (some) (sub)clinical mastitis cases with intramammary homeopathic substances consumed fewer antimicrobials than herds not applying such homeopathic treatments. Besides these factors, no other direct association was found between effective udder health management practices on the one hand and AMC on the other hand. Also, the use of critically important antimicrobials was only associated with the way in which subclinical mastitis cases were treated. The latter indicates that the AMC of critically important antimicrobials is potentially driven by factors other than those included in this study such as those related to the "mindset" of the veterinarians and their farmers. Future research should therefore aim to unravel the reasoning of vets and their farmers behind the use of those critically important antimicrobials for the treatment of mastitis and other diseases.

    Full Text Available Inflammation of the mammary gland, mastitis, in cows presents one of the most acute problems in intensive milk production, incurring huge economic losses which reach from 20-80% even in developed countries in the past decade. On the grounds of the programme of the respective Ministry, the Veterinary Service of the Republic of Serbia is obliged to monitor, detect, curb and control infective inflammation of the mammary gland caused by staphylococcus and streptococcus. Long-term different approaches to mastitis treatment did not result in the required solution, so that the problem of mastitis is still present and acute. In order to prevent the infiltration of the pathogenic cause into the mammary gland, its populating and multiplication, it is necessary to maintain constant and regular controls of milk, as well as undertake of preventive and therapeutic measures aimed at reducing the incidence of mastitis. Immunization and immunotherapy of mastitis are new and very interesting areas for scientific investigations and work. In the recent decades vaccines against staphylococcal mastitis are being successfully developed, whose success is reflected in the reduced incidence of clinical and subcilinical mastitis.

    Full Text Available Mycoplasmas are an important and economically significant cause of mastitis in dairy cows in various parts of the world. The organisms are highly contagious, with the main reservoir of infection originating from cows with subclinical mastitis. In 1998 the 1st cases of bovine mastitis due to Mycoplasma bovis were diagnosed in Ardabil State, Iran. An investigation was carried out with the aim of establishing the extent of mycoplasma infections in dairy cows in Ardabil State. Milk samples obtained from 80 cows with clinical mastitis were cultured in the laboratory for the presence of mycoplasmas. Similarly, 48 bulk-tank milk samples were examined for the presence of mycoplasmas. A modified Hayflick broth was used to isolate the mycoplasmas and an immunoperoxidase test used for the species identification of the isolates. Mycoplasma bovis was isolated from 39 (48.75 % of the clinical mastitis samples and from 48 of the bulk-tank milk samples tested. This indicated that mycoplasma udder infections were more prevalent in dairy cows in Ardabil State than previously thought.

    Objective: To find out the different clinical presentations of breast tuberculosis and its treatment outcome. Subjects and Methods: Fifty consecutive female patients above 13 years presenting with breast lump, multiple sinuses, axillary lymphadenopathy, and cold abscess were included in the study. Medical records of the patients presented were reviewed and analyzed. Data was collected regarding the patient's name, age and marital and lactational status. Clinical Examinations and investigations were carried out by triple assessment i.e. clinical, radiological and histological/cytological evaluation. Results: The commonest presentation was a solitary breast lump in 30 (60%) patients, breast lump with axillary lymphadenopathy in 13 (26%). Four (8%) patients presented with generalized breast swelling (edema) with ipsilateral axillary lymphadenopathy. Two (4) presented with breast abscess and axillary lymphadenopathy and one (2%) with axillary sinus and breast lump. Upper outer quadrant was most frequently involved in 29 (58%) of patients. Thirty two (64%) cases were secondary to tuberculosis in other sites, mostly (40%) from tuberculous axillary lymphadenitis. Forty eight (96%) patients responded well to one year antituberculous treatment with complete disappearance of the lumps except 2 patients who had shrinkage of lump size only, underwent excision of lump. Conclusion: Solitary lump and enlarged lymph nodes are the commonest presentation of mammary tuberculosis. Early diagnosis and treatment is necessary to prevent disfigurement of breast. Antituberculous therapy is the treatment of choice. Surgery should be reserved for unresponsive lumps. (author)

    Full Text Available Mastitis (inflammation of mammary gland is a most devastating disease condition in terms of economic losses occurring throughout the world. The etiological agents may vary from place to place depending on climate; animal species and animal husbandry and include wide variety of gram positive and gram negative bacteria; and fungi. They may be either contagious viz. Staphylococcus aureus; Streptococcus agalactiae or environmental viz. S. dysgalactiae, S. uberis, Corynebacterium bovis and Coagulase negative Staphylococcus. Conventional diagnostic tests viz. California Mastitis Test (CMT; R-mastitest and Mast-O-test methods are applied under field conditions; whereas somatic cell count and Bulk Tank Somatic Cell Count (BTSCC are useful for early mastitis detection and detection of sub clinical or chronic mastitis respectively. In vitro culture based diagnosis require further study as they can detect only viable cells. The advent of Polymerase Chain Reaction (PCR technology along with its various versions like multiplex and real time PCR has improved the rapidity and sensitivity of diagnosis. Circulating micro RNA (miRNA based diagnosis; immune assay and proteomics based detection along with biochips and biosensors prove to be asset to diagnosticians for advanced diagnosis of this economically important condition. Improvement of milking hygiene; implementation of post-milking teat disinfection; regular control of the milking equipments; implementation of milking order; Improvement of bedding material are the general measures to prevent new cases of mastitis. The use of antibiotics (intramammary infusions; bacteriocins and herbs (Terminalia spp. are important for prophylaxis and therapeutics. Vaccines viz. cell based; Recombinant (staphylococcal enterotoxin type C mutant or chimeric (pauA; live (S. uberis 0140J stain based and bacterial surface extract based; DNA-based and DNA-protein based have greatly aided in management of bovine mastitis. Quorum sensing and disease resistant breeding using novel biomarkers viz. toll like receptors (TLR 2 and 4, interleukin (IL 8; breast cancer type 1 susceptibility protein (BRCA1 and calcium channel voltage-dependent alpha 2/delta sub unit 1 (CACNA2D1 are also indispensable. This mini review gives an overview of all these different aspects that act as trend setters as far as the diagnosis and control of bovine mastitis is concerned to help the diagnosticians; epidemiologists and researchers not to remain ignorant about this grave condition.

    Full Text Available Streptococcus agalactiae is a major contagious pathogen causing bovine sub-clinical mastitis. The present investigation was carried out to determine some phenotypic characteristics of the S. agalactiae strains isolated from bovine mastitis cases in dairy cows of Shahrekord in the west-center of Iran. One hundred eighty California mastitis test (CMT positive milk samples were bacteriologically studied. A total of 31 (17.2% S. agalactiae isolated. Twenty eight (90.3% of the isolates were biofilm producers. This finding may indicate the high potential of pathogenicity in isolated strains. Sixteen (51.6% isolates were α hemolysin producers. Only 19.3%, 22.5% and 29.0% of the isolates were sensitive to streptomycin, flumequine and kanamycin, respectively. None of these three agents is recommended for treatment of mastitis cases.

    Mastitis affects the quality of milk and is a potential health risk for the other cows. In a well managed dairy herd, in addition to clinical mastitis, subclinical mastitis should be efficiently detected. Bacteriological sampling is not feasible as a routine test to identify subclinical mastitis, and indirect tests of mastitis are more suitable for selecting cows with intramammary infections for subsequent bacteriological sampling. Mastitis affects the composition of milk, and the degree of changes depends on the infecting agent and the inflammatory response. Indicators of inflammation in the milk which can be determined using rapid, reliable and easy routine techniques, can be used for the early detection of mastitis. The measuring of the somatic cell count in milk is the standard method, but the analysis technique is problematic for routine use in herds. The most promising parameters for monitoring subclinical mastitis are milk N-acetyl-beta-D-glucosaminidase activity, lactose, and electrical conductivity along with some other indicators such as optical and milk flow measurements, preferably with an inter-quarter evaluation included in the test. Acute phase proteins, haptoglobin and serum amyloid A, are also potential candidates for mastitis monitoring. New mastitis detection systems which can be adapted into on-line use are urgently needed, since dairy units are growing bigger and automatic milking systems are being taken into use. PMID:14556695

    Fast identification of pathogenic bacteria in milk samples from cows with clinical mastitis is central to proper treatment. In Denmark, time to bacterial diagnosis is typically 24 to 48 h when using traditional culturing methods. The PCR technique provides a faster and highly sensitive identification of bacterial pathogens, although shipment of samples to diagnostic laboratories delays treatment decisions. Due to the lack of fast on-site tests that can identify the causative pathogens, antibiotic treatments are often initiated before bacterial identification. The present study describes a flow cytometry-based method, which can detect and distinguish gram-negative and gram-positive bacteria in mastitis milk samples. The differentiation was based on bacterial fluorescence intensities upon labeling with biotin-conjugated wheat germ agglutinin and acridine orange. Initially 19 in-house bacterial cultures (4 gram-negative and 15 gram-positive strains) were analyzed, and biotin-conjugated wheat germ agglutinin and acridine orange florescence intensities were determined for gram-negative and gram-positive bacteria, respectively. Fluorescence cut-off values were established based on receiver operating characteristic curves for the 19 bacterial cultures. The method was then tested on 53 selected mastitis cases obtained from the department biobank (milk samples from 6 gram-negative and 47 gram-positive mastitis cases). Gram-negative bacteria in milk samples were detected with a sensitivity of 1 and a specificity of 0.74, when classification was based on the previously established cut-off values. However, when receiver operating characteristic curves were constructed for the 53 mastitis cases, results indicate that a sensitivity and specificity of 1 could be reached if cut-off values were reduced. This flow cytometry-based technique could potentially provide dairy farmers and attending veterinarians with on-site information on bacterial gram-type and prevent ineffective antimicrobial treatment in mastitis cases caused by gram-negative bacteria.

    Full Text Available Abstract The global dairy industry, the predominant pathogens causing mastitis, our understanding of mastitis pathogens and the host response to intramammary infection are changing rapidly. This paper aims to discuss changes in each of these aspects. Globalisation, energy demands, human population growth and climate change all affect the dairy industry. In many western countries, control programs for contagious mastitis have been in place for decades, resulting in a decrease in occurrence of Streptococcus agalactiae and Staphylococcus aureus mastitis and an increase in the relative impact of Streptococcus uberis and Escherichia coli mastitis. In some countries, Klebsiella spp. or Streptococcus dysgalactiae are appearing as important causes of mastitis.

    The global dairy industry, the predominant pathogens causing mastitis, our understanding of mastitis pathogens and the host response to intramammary infection are changing rapidly. This paper aims to discuss changes in each of these aspects. Globalisation, energy demands, human population growth and climate change all affect the dairy industry. In many western countries, control programs for contagious mastitis have been in place for decades, resulting in a decrease in occurrence of Streptococcus agalactiae and Staphylococcus aureus mastitis and an increase in the relative impact of Streptococcus uberis and Escherichia coli mastitis. In some countries, Klebsiella spp. or Streptococcus dysgalactiae are appearing as important causes of mastitis. Differences between countries in legislation, veterinary and laboratory services and farmers' management practices affect the distribution and impact of mastitis pathogens. For pathogens that have traditionally been categorised as contagious, strain adaptation to human and bovine hosts has been recognised. For pathogens that are often categorised as environmental, strains causing transient and chronic infections are distinguished. The genetic basis underlying host adaptation and mechanisms of infection is being unravelled. Genomic information on pathogens and their hosts and improved knowledge of the host's innate and acquired immune responses to intramammary infections provide opportunities to expand our understanding of bovine mastitis.

    Subclinical mastitis (SCM) represents a major proportion of the burden of mastitis. Determining somatic cell count (SCC) and electrical conductivity (EC) of milk are useful approaches to detect SCM. In order to correlate grades of SCM with the load of five major mastitis pathogens, 246 milk samples from a handful of organized and unorganized sectors were screened. SCC (>5 × 105/mL) and EC (>6.5 mS/cm) identified 110 (45 %) and 153 (62 %) samples, respectively, to be from SCM cases. Randomly s...

    The antimicrobial properties of copper have been recognized for several years; applying these properties to the prevention of diseases such as bovine mastitis is a new area of research. The aim of the present study was to evaluate in vitro the antimicrobial activity of copper on bacteria isolated from subclinical and clinical mastitis milk samples from two regions in Chile. A total of 327 microorganisms were recovered between March and September 2013, with different prevalence by sample origin (25 and 75% from the central and southern regions of Chile, respectively). In the central region, Escherichia coli and coagulase negative Staphylococci (CNS) were the most frequently detected in clinical mastitis cases (33%), while in the southern region S. uberis, S. aureus, and CNS were detected with frequencies of 22, 21, and 18%, respectively. Antibiotic susceptibility studies revealed that 34% of isolates were resistant to one or more antibiotics and the resistance profile was different between bacterial species and origins of isolation of the bacteria. The minimum inhibitory concentration of copper (MIC-Cu) was evaluated in all the isolates; results revealed that a concentration as low as 250 ppm copper was able to inhibit the great majority of microorganisms analyzed (65% of isolates). The remaining isolates showed a MIC-Cu between 375 and 700 ppm copper, and no growth was observed at 1000 ppm. A linear relationship was found between the logarithm of viable bacteria number and time of contact with copper. With the application of the same concentration of copper (250 ppm), CNS showed the highest tolerance to copper, followed by S. uberis and S. aureus; the least resistant was E. coli. Based on these in vitro results, copper preparations could represent a good alternative to dipping solutions, aimed at preventing the presence and multiplication of potentially pathogenic microorganisms involved in bovine mastitis disease.

    Nutritional factors that are linked to mastitis in the mature dairy cow can be associated with mastitis in the first lactation cow as well. However, there may also be risk factors unique to the heifer due to differences in feeding management during rearing or pre-calving. Literature was reviewed to summarize current knowledge regarding links between heifer nutrition and mastitis with the potential to identify areas for future research. The preponderance of data relating nutrition and bovine mastitis involves selected micronutrients. Selenium and vitamin E enhance phagocytic activity and have been associated with decreased clinical mastitis risk. Copper has antioxidant functions and can reduce clinical mastitis in heifers. Zinc is implicated in maintaining the epithelial barriers to infection, but reports vary as to its role in udder health. Vitamin A and beta-carotene aid in maintaining the health of mucosal surfaces, and beta-carotene may also have antioxidant properties. Supplementation with vitamin A and beta-carotene has produced inconsistent results. Vitamin and mineral requirements of dairy heifers are generally influenced by growth rate and body weight relative to mature size, though little specific data is available. From a management standpoint, heifer rations should be supplemented where necessary, and a pre-fresh heifer diet is critical to assure that first lactation animals have adequate stores of minerals and vitamins. Adequate stores are necessary for transfer into colostrum by calving. Additional studies using field data and controlled studies are needed to further define the role of nutrition in animal health and in affecting specific mastitis-causing organisms. PMID:18947943

Abstract in english The aim of this work was to identify and to characterise Staphylococcus aureus isolates associated with subclinical mastitis obtained from milk of lactating cows showing a California Mastitis Test (CMT) score result of traces, 1, 2, or 3. Coagulase, hemolysis, presence of capsule, slime formation, b [...] iofilm production, autoaggregation, hemagglutination and antibiotic susceptibility were assessed to evaluate S. aureus virulence factors expression potentially associated to bovine subclinical mastitis isolates. Prevalence of subclinical mastitis along the study was low and did not correlate with months or climatic variables. Most of S. aureus (20) were isolated from milk samples showing a CMT score result of 1. Formation of capsule, slime, biofilms and the occurrence of bacteria aggregation in all the tested isolates converged in the bacterial ability of adherence and persistence in the mammary gland and probably contribute to the further chronicity of the infection and even the colonization of dairy installations. Resistance against a set of commonly used antibiotics was low. The evaluation of virulence factors of S. aureus isolates in the context of subclinical mastitis in dairy farms may be useful to develop precise actions and treatments to control mastitis and to improve animal health and milk production in dairy bovine herds.

  9. Association between Hyperprolactinemia and Granulomatous Mastitis.

    2016-03-01

    Granulomatous mastitis (GM) is a relatively uncommon inflammatory breast lesion with multiple suggested etiologies. Although most GM cases show association with lactation and pregnancy, a minority of cases have been linked to hyperprolactinemia caused by either dopamine antagonist medications or with intracranial lesions, such as pituitary adenoma. The goal of this study is to review the GM cases reported in the literature with a specific emphasis on those cases associated with hyperprolactinemia and prolactinomas and to identify cases of GM seen at the Cleveland Clinic Florida which demonstrate co-occurrences of GM and intracranial lesions. CoPath and Epic data bases at Cleveland Clinic Florida were searched for cases describing inflammatory breast lesions in patients with pituitary pathology. Chart reviews were conducted and pertinent medical history was extracted for case reports. H&E-stained paraffin-embedded sections retrieved from Cleveland Clinic Florida pathology storage were evaluated by light microscopy. Four cases showing a co-occurrence of GM and hyperprolactinemia were consequently identified. A prolactin-secreting pituitary adenoma was present in two of the three GM cases. The third case demonstrated a concomitant craniopharyngioma, which was also associated with a rise in serum prolactin. This phenomenon was presumably attributable to compression, resulting in compromised transport of dopamine to the adenohypophysis and subsequent disinhibition of prolactin secretion by lactotrophs. The fourth patient with GM had a similar history of elevated prolactin. Classical histopathological features of GM were found in all four cases, including noncaseating granulomas, multinucleated giant cells, epithelioid histiocytes, and chronic inflammation. Intriguingly, complete resolution of inflammatory breast lesions along with normalization of prolactin levels occurred following the surgical excision of the craniopharyngioma, suggesting that intracranial lesion-induced hyperprolactinemia might be directly causal in GM. Therefore, the authors would suggest screening for pituitary tumors and evaluate prolactin levels in the workup of GM patients without a recent history of lactation and pregnancy and no other identified etiology.

    Staphylococcus caprae is an emerging microorganism in human bone and joint infections (BJI). The aim of this study is to describe the features of S. caprae isolates involved in BJI (H for human) compared with those of isolates recovered in goat mastitis (A for animal). Fourteen isolates of each origin were included. Identifications were performed using a Vitek 2 GP ID card, tuf gene sequencing, and matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) Vitek MS. Molecular typing was carried out using pulsed-field gel electrophoresis (PFGE) and DiversiLab technology. The crystal violet method was used to determine biofilm-forming ability. Virulence factors were searched by PCR. Vitek MS technology provides an accurate identification for the two types of isolates compared to that of gold-standard sequencing (sensitivity, 96.4%), whereas the Vitek 2 GP ID card was more effective for H isolates. Molecular typing methods revealed two distinct lineages corresponding to the origin despite few overlaps: H and A. In our experimental conditions, no significant difference was observed in biofilm production ability between H and A isolates. Nine isolates (5 H isolates and 4 A isolates) behaved as weak producers while one A isolate was a strong producer. Concerning virulence factors, the autolysin atlC and the serine aspartate adhesin (sdrZ) genes were detected in 24 isolates (86%), whereas the lipase gene was always detected, except in one H isolate (96%). The ica operon was present in 23 isolates (82%). Fibrinogen-binding (fbe) or collagen-binding (cna) genes were not detected by using primers designed for Staphylococcus aureus or Staphylococcus epidermidis, even in low stringency conditions. Although S. caprae probably remains underestimated in human infections, further studies are needed to better understand the evolution and the adaptation of this species to its host. PMID:26511738

    The present study aimed evaluate an on-farm culture system for identification of milk pathogens associated with clinical mastitis in dairy cows using two different gold standard approaches: standard laboratory culture in study 1 and 16S rRNA sequencing in study 2. In study 1, milk from mastitic quarters (i.e. presence of flakes, clots, or serous milk; n = 538) was cultured on-farm using a single plate containing three selective chromogenic media (Accumast—FERA Animal Health LCC, Ithaca, NY) and in a reference laboratory using standard culture methods, which was considered the gold standard. In study 2, mastitic milk was cultured on-farm and analyzed through 16S rRNA sequencing (n = 214). In both studies, plates were cultured aerobically at 37°C for 24 h and read by a single technician masked to gold standard results. Accuracy, sensitivity, specificity, positive (PPV) and negative predictive value (NPV) were calculated based on standard laboratory culture in study 1, and PPV was calculated based on sequencing results in study 2. Overall accuracy of Accumast was 84.9%. Likewise, accuracy for identification of Gram-negative bacteria, Staphylococcus sp., and Streptococcus sp. was 96.4%, 93.8%, and 91.5%, respectively. Sensitivity, specificity, PPV, and NPV were 75.0%, 97.9%, 79.6%, and 97.3% for identification of E. coli, 100.0%, 99.8%, 87.5%, and 100.0% for S. aureus, 70.0%, 95.0%, 45.7%, and 98.1% for other Staphylococcus sp., and 90.0%, 92.9%, 91.8%, and 91.2% for Streptococcus sp. In study 2, Accumast PPV was 96.7% for E. coli, 100.0% for Enterococcus sp., 100.0% for Other Gram-negatives, 88.2% for Staphylococcus sp., and 95.0% for Streptococcus sp., respectively. In conclusion, Accumast is a unique approach for on-farm identification pathogens associated with mastitis, presenting overall sensitivity and specificity of 82.3% and 89.9% respectively.

    This study evaluated the superantigen gene profiles, genetic relatedness and biological activity of exosecretions of 50 Staphylococcus aureus isolates obtained from milk of cows with clinical mastitis. Genomic relatedness of S. aureus was determined by pulsed field gel electrophoresis analysis of macro-restricted chromosomes. The presence of genes encoding superantigens was confirmed by multiplex PCR. To study the biological activity of S. aureus exosecretions, the supernatants from bacterial liquid cultures were classified into three groups: those with leukotoxin‐like properties, those with superantigen‐like properties and those with no particular activity on leukocytes cultured in vitro. It was shown that all analyzed bacterial isolates belonged to the same clonal type and harbored the same combination of superantigen genes, namely sed, selj and ser. However, 22% of all isolates produced factors with superantigen‐like and 48% of them with leukotoxin‐like activities. Finally, although there were no detectable genetic differences between the analyzed bacterial isolates, the virulence factors secreted by them differed considerably. PMID:24273801

    Full Text Available OBJECTIVE: Neonatal breast hypertrophy is a common phenomenon in term infants, superadded infection can lead to mastitis and that can progress to breast abscess with short and long term detrimental effects. Our effort is to study the prevalence, risk factors, the current microbial profile and sensitivity pattern in these infections in order to suggest an optimal treatment plan for these patients. DESIGN: Case series. SETTING: Hospital based study conducted in Kashmir on the native population. DURATION: 2011 to 2013. MATERIALS AND METHODS: 32 neonates with features of mastitis or abscess were included in the study. Demographic and clinical data, laboratory work-up were recorded for all these patients in a patient form. Gram stain of the purulent nipple discharge or pus obtained on drainage was done and the specimens were culture plated. Antibiotic sensitivity was determined by disk diffusion and categorized by current Clinical and Laboratory Standards Institute (CLSI guidelines. RESULTS: Most babies were full term, the age range was 6-48 days. Peak incidence for mastitis was in the 2nd week and for abscess in the 4th week. The ratio of male: female was 1:2 in the entire group, there was greater preponderance of female involvement with increasing age. Massage for expression of secretions a common practice in the study population had been done in 15 patients, especially in male babies. The babies were generally well and associated skin pustulosis was common. Laboratory workup showed polymorphonuclear leucocytosis and CRP positivity. Gram staining showed gram positive cocci in 13 patients and gram negative rods in 1 patient. Culture revealed Staphylococcus aureus in 18, E.col in 2, klebsiella in 1 patient and was sterile in 2 patients. Most strains of Staphylococcus aureus were resistant to macrolides and penicillins. Fifteen were methicillin sensitive and 3 were resistant but were sensitive to amikacin, ofloxacin and vancomycin. Gram negative rods were sensitive to, aminoglycosides, chloramphenicol, quinolones, piperacillin-tazobactum and cefoperazone-sulbactum, but were resistant to cephalosporins including third generation cephalosporins. Treatment with oral antibiotic was not successful. Patients responded well to open drainage via a stab incision away from the breast mound; 4 patients were managed by repeated needle aspirations. IV antibiotics were prescribed in all patients for 2-5 days, followed by oral continuation therapy of 7-14 days. CONCLUSIONS: From our study, we can conclude that parental counseling to avoid massage, and early treatment for pustulosis is important to prevent mastitis. Intravenous antibiotics should be used for this condition guided by gram stain or culture sensitivity once available. Empirically a drug with good anti-staph cover may be instituted till appropriate reports are available. Incision drainage gives uniformly good results, though; multiple sittings of needle drainage may obviate the need for incision drainage. Therapy can be shifted to oral drugs once clinical improvement is seen.

Methods: A randomized double-blind, placebo-controlled study including 63 breastfeeding women with lactational mastitis were randomly assigned to receive curcumin topical cream, one pump every 8 hours for 3 days (n=32 or topical moisturizer as placebo (n=31. Using an index for severity of breast inflammation, all of the patients had moderate breast inflammation before entering the study. The outcome of treatment was evaluated using the same index at 24, 48 and 72 hours of starting the treatment. Results: There was no significant difference between two study groups regarding the baseline characteristics such as age (p=0.361 and duration of lactation (p=0.551. After 72-hour of therapy, patients in curcumin groups had significantly lower rate of moderate (p=0.019 and mild (p=0.002 mastitis. Patients in curcumin group had significantly lower scores for tension (p<0.001, erythema (p<0.001 and pain (p<0.001, after 72-hour of treatment. Conclusion: The results of the current study indicate that topical preparation of curcumin successfully decrease the markers of lactational mastitis such as pain, breast tension and erythema within 72 hours of administration without side effects. Thus, topical preparation of curcumin could be safely administered for those suffering from lactational mastitis after excluding infectious etiologies.

    Full Text Available The primary objective of this study was to determine the aetiology of bovine mastitis in ten herds of Holstein Friesian cow in Jordan, the prevalence of mastitis pathogens in dairy cows and their resistance to selected antimicrobial agents. Milk samples were collected from 220 lactating cows to determine the clinical and subclinical mastitis by white side test and confirmed by cultural tests. It was found that 138 quarters (15.7% had been diagnosed as clinical mastitis with definite gross pathological lesions and change in udder secretion, in addition to that 276 quarters (31.4% showed subclinical mastitis. The incidence of mastitis was found to be increased in older cows. Staphylococcus aurous was considered to be the most common cause of both clinical and subclinical mastitis and followed by coli forms, streptococcus spp., corynebacterium spp., proteus spp. and pseudomonas spp. Sensitivity tests were applied to different isolated strains using tertracycline, ampicillin, neomycin, erythromycin, penicillin G and sulphamethoxazol trimethoprim.

    Full Text Available Postherpetic neuralgia (PHN is the most common complication of Herpes Zoster, characterized by the presence of neuropathic-type pain limited to a dermatomic area after outbreak of Herpes Zoster (commonly known as shingles, usually a month after the appearance of vesicles on the skin . The aim of this report is to present two cases of PHN and their responses to different treatments. The first case presented intolerance to amitriptyline and a good clinical response to gabapentin at a dose of 900 mg/day. The second case showed intolerance to capsaicin but responded well to the combination of pregabalin and topical lidocaine. Gabapentin, pregabalin and lidocaine are effective for the treatment of postherpetic neuralgia. All these recommendations are consistent with those treatments used by the family physicians in the two cases study presented.

    Full Text Available Background: The aim of this study was identification of the epidemiology of Prototheca zopfii species from the milk samples of dairy cattle in Isfahan, central Iran.Methods: Milk samples were obtained from 230 dairy cattle, 130 with and 100 without mastitis, in Isfahan. The samples were cultured in Prototheca Isolation Medium (PIM and Sabouraud's dextrose agar. All P. zopfii isolates were identified by morphological and biochemical methods. Then, as a confirmatory test they were examined by genotype-specific PCR.Results: Four P. zopfii strains (3.07% were isolated from the 130 samples of dairy cattle with clinical mastitis and there was no isolation from totally 100 samples of healthy bovines without mastitis. Specific PCR product (about 946 bp was detected in four isolates.Conclusion: It seems that P. zopfii genotype II plays a key role in affecting bovine mastitis that confirmed other previous studies. Our study was the first, which identified the Prototheca species by traditional and molecular methods in Iran and Middle East as well.

    Vaccination can play a useful role in mastitis control programs, although there is a relative dearth of large, well-controlled field efficacy studies. This paper presents the findings on the use of a commercially available vaccine (Startvac, Hipra UK Ltd., Nottingham, UK) on commercial units under UK field conditions. In total, 3,130 cows were recruited from 7 farms and were randomly allocated, within farm, to 1 of 3 groups. The first group received the vaccine following the label regimen, the second group was vaccinated every 90 d following an initial vaccination course, and the third group was left unvaccinated to act as controls. Vaccine efficacy was assessed in the first 120 d of lactation. Data were available for analysis from 1,696 lactations in 1,549 cows. In total, 779 cases of clinical mastitis occurred in the 3 study groups, and we detected no significant difference in the incidence or prevalence of clinical or subclinical mastitis between any of the 3 groups. Mastitis vaccination following the label regimen was associated with a significant reduction in the severity of clinical cases. Cows in this group were at significantly decreased odds of developing clinical mastitis presenting with more than just milk changes [odds ratio: 0.58; 95% confidence interval (CI): 0.35-0.98]. Similarly, each additional vaccination resulted in a cow being at decreased odds of developing clinical mastitis presenting with more than just milk changes (odds ratio: 0.87; 95% CI: 0.77-0.98). Although no cows were culled because of severe mastitis in either of the vaccinated groups, we detected no significant difference in the mastitis-related culling rate between groups. Analysis of milk production data demonstrated that, on average, cows on the label regimen produced a higher volume of milk (231 L; 95% CI: 104.1-357.4) and more milk solids (12.36 kg; 95% CI: 3.12-21.60) than unvaccinated cows in the first 120 d of lactation. Conservative analysis suggested that a return on investment of 2.57:1 could be expected under UK conditions based on increased milk yield alone. PMID:25529419

    A dynamic deterministic biological model was developed that generates, for a given cow on a given day, a value for her risk of having mastitis. The model combines real-time information from a mastitis indicator measured in milk with additional factors that are other known risk factors of mastitis but that are not reflected in the indicator. l-Lactate dehydrogenase (LDH), an enzyme whose activity is increased because of mastitis, is used as an example of a mastitis indicator. The additional factors incorporated in the model are days from calving, breed, parity, milk yield, udder characteristics, other disease records, electrical conductivity, and herd characteristics. The model is designed to run each time a new LDH value is recorded and can run in the absence of the additional factors. Electrical conductivity measurements and disease records, where available, also trigger the model to run. As an input, milk LDH activity values (micromol/min per L) are multiplied by milk yield (L) to produce the amount of LDH (micromol/min) and are then smoothed using an extended Kalman filter before being processed by the biological model. The output comprises a risk of acute mastitis and a relative degree of chronic mastitis. The model also produces a days-to-next sample value that allows sampling frequency to be either increased or reduced depending on the risk of mastitis. The days-to-next sample value was designed to make the best use of opportunities afforded by automated, inline sampling technology. The model functionality was investigated using simulated data, and real-farm data of naturally occurring mastitis were then used to validate the model. The results demonstrated that the model is robust to sampling frequency and random noise in the LDH measurements. It was able to detect mastitis reasonably well: Using a threshold mastitis risk of 0.7, sensitivity for detecting clinical mastitis was 82%. Specificity, that is, the ability to avoid misclassifying healthy observations as mastitis, was 99%. PMID:16840614

    Foot and mouth disease (FMD) is a highly transmissible viral infection of cloven hooved animals associated with severe economic losses when introduced into FMD-free countries. Information on the impact of the disease in FMDV-endemic countries is poorly characterised yet essential for the prioritisation of scarce resources for disease control programmes. A FMD (virus serotype SAT2) outbreak on a large-scale dairy farm in Nakuru County, Kenya provided an opportunity to evaluate the impact of FMD on clinical mastitis and culling rate. A cohort approach followed animals over a 12-month period after the commencement of the outbreak. For culling, all animals were included; for mastitis, those over 18months of age. FMD was recorded in 400/644 cattle over a 29-day period. During the follow-up period 76 animals were culled or died whilst in the over 18month old cohort 63 developed clinical mastitis. Hazard ratios (HR) were generated using Cox regression accounting for non-proportional hazards by inclusion of time-varying effects. Univariable analysis showed FMD cases were culled sooner but there was no effect on clinical mastitis. After adjusting for possible confounders and inclusion of time-varying effects there was weak evidence to support an effect of FMD on culling (HR?=?1.7, 95% confidence intervals [CI] 0.88-3.1, P?=?0.12). For mastitis, there was stronger evidence of an increased rate in the first month after the onset of the outbreak (HR?=?2.9, 95%CI 0.97-8.9, P?=?0.057). PMID:25889460

    Automated detection of diseases (such as mastitis) in dairy cows might be an alternative for detection by observation during milking - especially when using an automatic milking system (AMS). An outline of a detection model is given. This detection model includes time-series models for two variables (milk yield and electrical conductivity of milk), with interpolation on previous values. The model is flexible in the number of variables actually used. Parameter values and the residual variances are updated by linear regression after each milking. Alerts for mastitis are given when the residuals fall outside given confidence intervals. A data set with 111 cows for 16 months (on average, 58 lactating cows per day) was used to test the model. Depending on the chosen confidence interval, 42-44 out of 48 cases of clinical mastitis were detected; the remaining cases were not detected because not all data needed were available. These results were better than the results obtained with the model usually used on the farm. The number of false-positive alerts depended on the chosen confidence interval and was higher than the number found with the model usually used. PMID:11267690

    2001-07-01

    Full Text Available Abstract Genetic analysis for mastitis resistance was studied from two data sets. Firstly, risk factors for different mastitis traits, i.e. culling due to clinical or chronic mastitis and subclinical mastitis predicted from somatic cell count (SCC, were explored using data from 957 first lactation Lacaune ewes of an experimental INRA flock composed of two divergent lines for milk yield. Secondly, genetic parameters for SCC were estimated from 5 272 first lactation Lacaune ewes recorded among 38 flocks, using an animal model. In the experimental flock, the frequency of culling due to clinical mastitis (5% was lower than that of subclinical mastitis (10% predicted from SCC. Predicted subclinical mastitis was unfavourably associated with the milk yield level. Such an antagonism was not detected for clinical mastitis, which could result, to some extent, from its low frequency or from the limited amount of data. In practice, however, selection for mastitis resistance could be limited in a first approach to selection against subclinical mastitis using SCC. The heritability estimate of SCC was 0.15 for the lactation mean trait and varied from 0.04 to 0.12 from the first to the fifth test-day. The genetic correlation between lactation SCC and milk yield was slightly positive (0.15 but showed a strong evolution during lactation, i.e. from favourable (-0.48 to antagonistic (0.27. On a lactation basis, our results suggest that selection for mastitis resistance based on SCC is feasible. Patterns for genetic parameters within first lactation, however, require further confirmation and investigation.

  7. Staphylococcus aureus seroproteomes discriminate ruminant isolates causing mild or severe mastitis

    Full Text Available Abstract Staphylococcus aureus is a major cause of mastitis in ruminants. In ewe mastitis, symptoms range from subclinical to gangrenous mastitis. S. aureus factors or host-factors contributing to the different outcomes are not completely elucidated. In this study, experimental mastitis was induced on primiparous ewes using two S. aureus strains, isolated from gangrenous (strain O11 or subclinical (strain O46 mastitis. Strains induced drastically distinct clinical symptoms when tested in ewe and mice experimental mastitis. Notably, they reproduced mild (O46 or severe (O11 mastitis in ewes. Ewe sera were used to identify staphylococcal immunoreactive proteins commonly or differentially produced during infections of variable severity and to define core and accessory seroproteomes. Such SERological Proteome Analysis (SERPA allowed the identification of 89 immunoreactive proteins, of which only 52 (58.4% were previously identified as immunogenic proteins in other staphylococcal infections. Among the 89 proteins identified, 74 appear to constitute the core seroproteome. Among the 15 remaining proteins defining the accessory seroproteome, 12 were specific for strain O11, 3 were specific for O46. Distribution of one protein specific for each mastitis severity was investigated in ten other strains isolated from subclinical or clinical mastitis. We report here for the first time the identification of staphylococcal immunogenic proteins common or specific to S. aureus strains responsible for mild or severe mastitis. These findings open avenues in S. aureus mastitis studies as some of these proteins, expressed in vivo, are likely to account for the success of S. aureus as a pathogen of the ruminant mammary gland.

    The prevalence of mastitis and brucellosis in urban and peri-urban settings was studied in Awassa and two smaller nearby towns in southern Ethiopia, because milk-born diseases are causing a risk for human health, besides direct impacts on animal production. Mastitis was investigated by examining 80 cows (320 udder quarters) using California mastitis test (CMT) and somatic cell count (SCC). The prevalence of brucellosis was assessed by sampling 177 cattle in Awassa and its peri-urban areas using serological methods. Logistic regression was used to analyse risk factors associated with mastitis. Prevalence of clinical mastitis on quarter level was 0.9%, and 1.9% of quarters were non-functional or blocked. Prevalence of sub-clinical mastitis at quarter level in urban and peri-urban areas was significantly different (P milk and milk products is indicated in some parts of the area because of the danger of brucellosis.

    Twenty-one dairy ewe flocks selected by stratified random sampling were subjected to study the prevalence and etiology of subclinical intramammary infections and to assess the influence of parity on the prevalence of intramammary infections. Also, spontaneous cure rates were determined over study period. A total of 1192 milk samples were collected at 2 weeks after lambing until tenth-week postpartum. All flocks had hand milking; those which were classified by bacterial culture and California Mastitis Test (CMT) as positive were deemed to have glands with subclinical mastitis (SCM). Of 1192 halves examined, 791 samples were collected during spring and 401 samples were collected during summer. Prevalence rate of SCM in spring was 14.7 %; and spontaneous cure that occurred in this season was 88.8 %; coagulase-negative staphylococci (CNS) were the most common isolates (66.6 %). Samples collected in spring showed higher prevalence rate of SCM than summer samples. This rate was 8.9 % in summer. Spontaneous cure rate in this season was 69.4 %, and Staphylococcus aureus (72.2 %) was the most common isolates. SCM was seen at significantly lower rates in left half than in right one (p?clinical mastitis (defined as number of clinical cases per 100 ewe-months) was 0.21 and 0.74 in spring and summer, respectively. The isolates from clinical cases in spring were fungi and, from summer, were S. aureus. Also, S. aureus SCM cases were not significantly severe than other SCM cases. In conclusion, multiparous ewes were most at risk, and severity of infection was higher in summer. PMID:26041046

    Breast tuberculosis is a rare form of extrapulmonary tubercular infection. Our aim is to highlight the nonspecific clinical presentations, diagnostic difficulties and therapeutic approaches of mammarian tuberculosis. Forty-six patients diagnosed with breast tuberculosis between 2005 and 2015 were reviewed retrospectively. Clinical features, all diagnostic methods, and the outcomes of treatment were analysed. All cases were female with a mean age of 36.4years. Breast mass and pain were the most common complaints. While 34.8% of the cases had a physical examination with suspicions for malignancy, 43.5% of the patients had Breast Imaging Reporting and Data System (BI-RADS) 4 or 5 lesions suggested malignancy radiologically. Definitive diagnosis was based on histopathologic examination through core needle biopsy (n=29), excisional biopsy (n=12), and open biopsy (n=5) taken from the abscess wall during drainage. Standard antiTB therapy for 6months was given to all cases. Thirty-three patients recovered with standard 6-month therapy while extended treatment for 9-12months was needed in 13 (28.2%) cases. Surgery was carried out in 17 cases. Two patients developed recurrence. Breast tuberculosis can be easily confused with breast cancer, suppurative abscess, and other causes of granulomatous mastitis, both clinically and radiologically. A multidisciplinary approach is required to prevent diagnostic delays and unnecessary surgical interventions. Although antiTB therapy is the mainstay treatment of breast TB, surgery is usually indicated in patients refractory to medical treatment. PMID:26853172

    Full Text Available Tuberculous mastitis is a rare clinical entity and usually affects women from the Indian sub-continent and Africa. It often mimics breast carcinoma and pyogenic breast abscess clinically and radiologically, may both co-exist. Routine laboratory investigations are not helpful in its diagnosis. Fine needle aspiration cytology (FNAC / biopsy are essential for diagnosis and tuberculosis culture when positive may be very useful to guide antimicrobial therapy. Antitubercular drugs in combination with aspiration or surgical drainage are usually associated with an excellent outcome.

    Full Text Available Introducción: La mastitis granulomatosa crónica lobular idiopática es una patología benigna del seno, de carácter inflamatorio y de etiología desconocida. Sus principales manifestaciones clínicas se semejan a las del cáncer mamario. Dado que los hallazgos clínicos y de imágenes diagnósticas no son específicas, el diagnóstico inequívoco recae en el estudio histopatológico de 0 lesión. Objetivos: Describir las principales manifestaciones clínicas, los resultados de los métodos diagnósticos y hallazgos importantes de patología en los casos de mastitis granulomatosa crónica lobular idiopática. Materiales y métodos: Desde enero del año 2004 los autores establecieron el registro personal de tumores benignos, mastitis no lactacional y enfermedad inflamatoria ductal. Hasta septiembre de 2006, este registro recolectó información clínica, métodos diagnósticos y tratamiento en 77 pacientes, 20 de los cuales correspondieron al diagnóstico de mastitis granulomatosa crónica lobular idiopática. Se realizó análisis estadístico descriptivo por las siguientes variables: 1. Edad. 2. Cuadro clínico. 3. Enfermedades asociadas. 4. Métodos diagnósticos utilizados. 5. Hallazgos histopatológicos. 6. Curso clínico. Resultados: El diagnóstico de mastitis granulomatosa crónica lobular se hizo inicialmente en 30 pacientes. Se confirmó el diagnóstico de mastitis granulomatosa crónica lobular idiopática en 20 pacientes, dado que en 10, se identificó la causa específica de la inflamación granulomatosa del seno. La edad promedio de las pacientes fue de 36 años; la más joven tenía 22 años. La manifestación clínica más frecuente fue la aparición de masa inflamatoria en el seno. El hallazgo principal del estudio fue la asociación de mastitis granulomatosa crónica lobular idiopática con cáncer del seno contralateral y la infección con virus de inmunodeficiencia humana, asociación no descrita en la literatura mundial. Conclusión: El diagnóstico de mastitis granu-lomatosa crónica lobular idiopática es un reto clínico formidable. Debido a que sus manifestaciones clínicas son yerras y se observa resolución espontánea de la enfermedad, esta patología posiblemente es dejada sin diagnosticar en una proporción importante de casos. La identificación de la causa subyacente de la inflamación granulomatosa en más de un tercio de los pacientes, hace que el estudio histopatológico sea considerado por nosotros como el método diagnóstico de escogencia para el diagnóstico incuestionable de esta patología.Background: Chronic idiopathic granulomatous mastitis (ICGM is a benign disease of the breast, of inflammatory nature and unknown etiology. The main clinical features of this entity resemble those of mammary cancer. Given that the clinical and diagnostic imaging findings are not specific, the correct diagnosis falls in the histopathologic study. Objectives: To describe the main clinical manifestations, the results of the diagnostic studies, and the most important findings in the pathlogical study of ICGM. Materials and methods: Beginning in January 2004, the authors implemented the personal registry of benign breast tumors, nonlactational mastitis, and ductal inflammatory disease; 77 patients were registered until September 2006, with data including clinical information, diagnostic methods, and treatment modalities. In this group of 77 patients, 20 had the diagnosis of ICGM. A descriptive statistical analysis based on the following variables was carried out: 1. Age; 2. Clinical presentation; 3. Associated illnesses; 4. Diagnostic methods employed; 5. histopathologic findings; 6. Clinical course. Results: The diagnosis of ICGM was initially made in 30 patient, and the diagnosis was confirmed in 20, while in the other 10 a specific inflammatory cause was identified. The average age of this group patients was 36 years, the youngest being 22.The most frequent clinical presentation was an inflammatory mass in the breast, while the outstanding finding was the association of ICGM with contralateral breast cancer and infection with HIV, an association that has not been reported in the literature. Conclusion: The diagnosis of ICGN represents a formidable clinical challenge, by virtue of the ambiguous clinical manifestations and the fact that the entity tends to resolve spontaneously. Thus, it is possible that ICGM remains undiagnosed in a significant number of cases. The identification of the underlying cause of ICGM in more than one third of our patients indicates that the histopathologic study is the should be considered as the only certain diagnostic method.

    Subclinical mastitis (SCM) represents a major proportion of the burden of mastitis. Determining somatic cell count (SCC) and electrical conductivity (EC) of milk are useful approaches to detect SCM. In order to correlate grades of SCM with the load of five major mastitis pathogens, 246 milk samples from a handful of organized and unorganized sectors were screened. SCC (>5 × 10(5)/mL) and EC (>6.5 mS/cm) identified 110 (45 %) and 153 (62 %) samples, respectively, to be from SCM cases. Randomly selected SCM-negative samples as well as 186 samples positive by either SCC or EC were then evaluated for isolation of five major mastitis-associated bacteria. Of the 323 isolates obtained, 95 each were S. aureus and coagulase-negative staphylococci (CoNS), 48 were E. coli and 85 were streptococci. There was no association between the distribution of organisms and (a) the different groups of SCC, or (b) organised farms and unorganised sectors. By contrast, there was a significant difference in the distribution of CoNS, and not other species, between organized farms and unorganized sectors. In summary, bacteria were isolated irrespective of the density of somatic cells or the type of farm setting, and the frequency of isolation of CoNS was higher with organized farms. These results suggest the requirement for fine tuning SCC and EC limits and the higher probability for CoNS to be associated with SCM in organized diary sectors, and have implications for the identification, management and control of mastitis in India.

    Full Text Available The purpose of this paper was to study the etiology of mastitis, determine the antimicrobial susceptibility profile of Staphylococcus spp. and to identify the risk factors associated with infection in dairy cows in the states of Bahia and Pernambuco, Brazil. From the 2,064 milk samples analyzed, 2.6% were associated with cases of clinical mastitis and 28.2% with subclinical mastitis. In the microbiological culture, Staphylococcus spp. (49.1% and Corynebacterium spp. (35.3% were the main agents found, followed by Prototheca spp. (4.6% and Gram negative bacilli (3.6%. In the antimicrobial susceptibility testing, all 218 Staphylococcus spp. were susceptible to rifampicin and the least effective drug was amoxicillin (32.6%. Multidrug resistance to three or more drugs was observed in 65.6% of Staphylococcus spp. The risk factors identified for mastitis were the extensive production system, not providing feed supplements, teat drying process, not disinfecting the teats before and after milking, and inadequate hygiene habits of the milking workers. The presence of multiresistant isolates in bovine milk demonstrates the importance of the choice and appropriate use of antimicrobial agents. Prophylactic and control measures, including teat antisepsis and best practices for achieving hygienic milking should be established in order to prevent new cases of the disease in herds.

    Full Text Available ResumenEste artículo es una revisión bibliográfica sobre los métodos de detección de la mastitis bovina que se utilizan más comúnmente en el mundo. La mastitis bovina es la inflamación de la glándula mamaria causada por una infección por patógenos. Es una de las enfermedades más frecuentes de la producción que afecta a la industria lechera en todo el mundo. Puede presentarse de manera clínica y subclínica. La mastitis subclínica es de larga duración y es mucho más frecuente que la mastitis clínica. Dentro de los métodos que se usan con mayor frecuencia a nivel de campo para diagnosticar mastitis clínicas, se encuentran el método de observación y palpación de la ubre y las pruebas físicas, como la prueba de escudilla de ordeño, prueba del paño negro y taza probadora. Las pruebas químicas, como la prueba de conductividad eléctrica de la leche, papel indicador de mastitis y prueba de whiteside que sirven también para diagnosticar mastitis clínicas y subclínicas. Las pruebas biológicas, como son la prueba de California para mastitis, la prueba de Wisconsin, el diagnóstico bacteriológico por los métodos de aislamiento, cultivo, tinción, pruebas bioquímicas e identificación y el conteo de células somáticas por microscopia directa y el somaticell. Otros métodos utilizados actualmente por su rapidez y efectividad son los electrónicos como el fossomatic y el counter coulter, los cuales tienen una aplicación universal sobre todo en laboratorios de control lechero o dedicados al diagnóstico e investigación de la mastitis y el DeLaval cell counter. Los métodos de detección de mastitis son una herramienta que permite identificar el tipo de infección clínica o subclínica que puede presentarse dentro de un hato lechero, por lo que el método que se elija para determinar las pruebas será esencial para tener un diagnóstico más preciso.AbstractThis article is a bibliographical revision on the methods of detection of the bovine mastitis that is used more commonly in the world. The bovine mastitis is the inflammation of the mammary gland caused by an infection by pathogens. Is one of the most frequent diseases of the production that affects the milk industry anywhere in the world. It can appear of clinical and subclinical way. The subclinical mastitis is long play and is much more frequent that the clinical mastitis. Within the methods that are used most frequently at field level to diagnose clinical mastitis, are the method of observation and palpation of udder and the physical tests, as the container of milking test, the black cloth test and cup test. The chemical tests, like the electrical conductivity of milk test, paper test of mastitis and whiteside test that they also serve to diagnose clinical and subclinical mastitis. The biological tests, as they are the California mastitis test, the Wisconsin test, the bacteriological diagnosis by the methods of isolation, culture, biochemical stain, tests and identification, the count of somatic cells by direct microscope and somaticell. Other methods used at the moment by their rapidity and effectiveness are the electronic ones like the fossomatic, the counter coulter and the, which mainly have a universal application in laboratories of control milk or dedicated to the diagnosis and investigation of the mastitis and the DeLaval cell counter. The methods of detection of mastitis are a tool that allows to identify the type of clinical infection or subclinical that can appear within a milk cattle ranch, reason why the method that is chosen to determine the tests will be essential to have a more precise diagnosis.

  18. The disruptive effects of mastitis on reproduction and fertility in dairy cows

    Full Text Available Mastitis (intramammary infection causes the deterioration of ovarian follicular responses in cows, resulting in low fertility. The shortterm, acute clinical form of mastitis has a time-dependent disruptive effect on conception rate. It effectively lowers conception rate if events occur mainly 10 days before to 30 days after artificial insemination. Long-term subclinical mastitis is widely spread in commercial herds. Although it is less severe than clinical mastitis, its long-term nature causes a more pronounced decrease in conception rate. Even mild elevation of somatic cell count in subclinical cows significantly lowers conception rate. Disrupted follicular responses include depression of steroid production in the preovulatory follicle associated with low and delayed preovulatory luteinizing hormone surge, resulting in delayed ovulation in onethird of subclinical cows. Mastitis, clinical and subclinical, also impairs oocyte competence, reflected in low production of blastocysts. The corpus luteum seems to be insensitive to mastitis, possible due to the use of non-steroidal anti-inflammatory drugs when mastitis is first diagnosed.

    Developing a reliable mastitis challenge infection model is required to test new intramammary antimicrobial preparations, other novel bovine mastitis treatments, and study mastitis pathogenesis. Three treatment groups of Holstein Friesian cows in active lactation were administered two doses (10(4) and 10(6) cfu/quarter) on a single occasion with one of the three Streptococcus uberis strains (BFR6019, MFF1283 and SA002) suspended in 5 ml of sterile PBS, administered via intramammary inoculation immediately after milking. All quarters that were challenged with S. uberis strains MLF1283 and BFR6019 showed clinical signs of mastitis on day 1 and 2 after the challenge. Strain SA002 had a lower rate of inducing clinical mastitis which was detected later than day 3 after the challenge. We successfully developed a rapid and reliable model for inducing experimental S. uberis mastitis with 100% success rate in cows in active lactation. On the basis of the correlation results between strains, RAPD fingerprinting results, clinical findings, and a 100% success rate of mastitis induction for low and high doses S. uberis strains MLF1283 and BFR6019, strain virulence seems to be a more important effect than challenge dose in induction of clinical mastitis following experimental challenge.

    Full Text Available Clinical mastitis (CM is the most common veterinary treated disease in Swedish dairy cattle. To investigate if the distribution of veterinary registered cases of CM in Sweden follows that of the spatial distribution of cows with high somatic cell counts (SCCs, the spatial distribution of CM odds was estimated from available records and compared with udder health measures based on measurements of SCC derived from official milk recording. The study revealed areas with significantly lower odds for CM but with a high proportion of cows with a poor udder health score, suggesting an under-reporting of CM. We also found areas of significantly higher odds for CM despite a low proportion of cows with a poor udder health score, suggestive of over-treatment of mastitis. The results should enable targeted studies of reasons for discrepancies, e.g. farmers’ and veterinarians’ attitudes to mastitis treatment and disease recording in areas with a deficit or excess of registered CM cases. High quality disease records for dairy cattle are of interest not only for the dairy management but also for disease surveillance, monitoring of use of antibiotics and food safety purposes.

    The study objective was to compare the efficacy of 2 commercial dry cow mastitis formulations containing cloxacillin benzathine or ceftiofur hydrochloride. Quarter-level outcomes included prevalence of intramammary infection (IMI) postcalving, risk for cure of preexisting infections, risk for acquiring a new IMI during the dry period, and risk for clinical mastitis between dry off and 100d in milk (DIM). Cow-level outcomes included the risk for clinical mastitis and the risk for removal from the herd between dry off and 100 DIM, as well as Dairy Herd Improvement Association (DHIA) test-day milk component and production measures between calving and 100 DIM. A total of 799 cows from 4 Wisconsin dairy herds were enrolled at dry off and randomized to 1 of the 2 commercial dry cow therapy (DCT) treatments: cloxacillin benzathine (DC; n=401) or ceftiofur hydrochloride (SM; n=398). Aseptic quarter milk samples were collected for routine bacteriological culture before DCT at dry off and again at 0 to 10 DIM. Data describing clinical mastitis cases and DHIA test-day results were retrieved from on-farm electronic records. The overall crude quarter-level prevalence of IMI at dry off was 34.7% and was not different between treatment groups. Ninety-six percent of infections at dry off were of gram-positive organisms, with coagulase-negative Staphylococcus and Aerococcus spp. isolated most frequently. Mixed logistic regression analysis showed no difference between treatments as to the risk for presence of IMI at 0 to 10 DIM (DC=22.4%, SM=19.9%) or on the risk for acquiring a new IMI between dry off and 0 to 10 DIM (DC=16.6%, SM=14.1%). Noninferiority analysis and mixed logistic regression analysis both showed no treatment difference in risk for a cure between dry off and 0 to 10 DIM (DC=84.8%, SM=85.7%). Cox proportional hazards regression showed no difference between treatments in quarter-level risk for clinical mastitis (DC=1.99%, SM=2.96%), cow-level risk for clinical mastitis (DC=17.0%, SM=15.3%), or on risk for removal from the herd (DC=10.7%, SM=10.3%) between dry off and 100 DIM. Finally, multivariable linear regression with repeated measures showed no overall no difference between treatments in DHIA test-day somatic cell count linear score (DC=2.19, SM=2.22), butterfat test (DC=3.84%, SM=3.86%), protein test (DC=3.02%, SM=3.02%), or 305-d mature-equivalent milk production (DC=11,817kg, SM=11,932kg) between calving and 100 DIM. In conclusion, DC was noninferior to SM in effecting a cure, and there was no difference in efficacy between these 2 DCT formulations as related to all other udder health or cow performance measures evaluated between dry off and 100 DIM.

  6. THE INNATE IMMUNITY IN BOVINE MASTITIS: THE ROLE OF PATTERN-RECOGNITION RECEPTORS

    Directory of Open Access Journals (Sweden)

    Fernando Nogueira de Souza

    2012-01-01

    Full Text Available Mastitis is the most costly disease for dairy farmers and industry, which are mainly caused by the entry of bacteria to the teat canal. Shortly after the entry of the invading bacteria, the innate immunity recognizes the invading pathogen through pattern recognition receptors and initiates the inflammatory response necessary to eliminate the invading bacteria. This initial inflammatory response releases cytokines and chemoattractants for the rapid and massive influx of neutrophils from the blood to the site of infection which form the first line of cellular defense against bacteria This article reviewed the role of the most recent knowledge regarding the innate immunity in bovine mastitis focusing in the two major mastitis pathogens: Escherichia coli and Staphylococcus aureus the S. aureus appears to mostly circumvent the host immune response, as the Toll-Like Receptors (TLRs signaling pathways. The Intramammary Infections (IMIs by this bacteria result in a very moderate host response with minimal observable innate immune response, which are related to well-known ability to this pathogen to establish chronic IMI. Otherwise, E. coli elicits a strong and earlier response, mainly through TLR4, that is associated with the severity of the mastitis and the clinical manifestation commonly observed in dairy cows infected with this pathogen. Suboptimal and dysfunctional mammary defenses may contribute to the development of severe acute inflammation or chronic mastitis that adversely affects the milk production and quality. Thus, a better understanding of mastitis pathogen interaction to the host may be useful for future control of mastitis.

    Electrical conductivity (EC) of milk has been introduced as an indicator trait for mastitis over the last decade, and it may be considered as a potential trait in a breeding program where selection for improved udder health is included. In this study, various EC traits were investigated for their association with udder health. In total, 322 cows with 549 lactations were included in the study. Cows were classified as healthy or clinically or subclinically infected, and EC was measured repeatedly during milking on each quarter. Four EC traits were defined; the inter-quarter ratio (IQR) between the highest and lowest quarter EC values, the maximum EC level for a cow, IQR between the highest and lowest quarter EC variation, and the maximum EC variation for a cow. Values for the traits were calculated for every milking throughout the entire lactation. All EC traits increased significantly (P < 0.001) when cows were subclinically or clinically infected. A simple threshold test and discriminant function analysis was used to validate the ability of the EC traits to distinguish between cows in different health groups. Traits reflecting the level rather than variation of EC, and in particular the IQR, performed best to classify cows correctly. By using this trait, 80.6% of clinical and 45.0% of subclinical cases were classified correctly. Of the cows classified as healthy, 74.8% were classified correctly. However, some extra information about udder health status was obtained when a combination of EC traits was used. PMID:15259246

    Although the 16-membered macrolide tylosin is commonly used for the treatment of bovine mastitis, little information is currently available about the susceptibility of mastitis pathogens to tylosin. In the present study, 112 Staphylococcus aureus and 110 coagulase-negative Staphylococcus (CoNS) spp. isolates from cases of bovine mastitis were tested by broth microdilution and agar disk diffusion with 30 ?g tylosin disks. Susceptibility to erythromycin was tested by broth microdilution and disk diffusion using 15 ?g disks. Both test populations showed bimodal distributions of minimal inhibitory concentrations (MICs) and zone diameters with eleven S. aureus and eight CoNS isolates showing tylosin MICs of ? 256 ?g/ml and no zones of growth inhibition around the tylosin 30 ?g disks. All 19 isolates with tylosin MICs of ? 256 ?g/ml were also resistant to erythromycin. For six additional erythromycin-resistant isolates, tylosin MICs of 1-8 ?g/ml were observed. One S. aureus and two CoNS isolates showed inducible macrolide resistance. PCR analysis of the 25 erythromycin-resistant staphylococcal isolates identified the resistance genes erm(A), erm(B), erm(C), erm(T), mph(C) and msr(A) alone or in different combinations. An excellent correlation between the results of the different tylosin susceptibility tests (broth microdilution versus disk diffusion) was seen for S. aureus and CoNS isolates. Since tylosin does not induce the expression of the aforementioned erm genes, isolates with an inducible resistance phenotype may - if only tylosin is tested - be falsely classified as tylosin-susceptible. Thus, erythromycin should be tested in parallel and tylosin should only be used for the treatment of infections caused by erythromycin-susceptible staphylococci. PMID:24461550

    Intense selection to increase milk yield has had negative consequences for mastitis incidence in dairy cattle. Due to low heritability of mastitis resistance and an unfavorable genetic correlation with milk yield, a reduction in mastitis through traditional breeding has been difficult to achieve....... Here, we examined quantitative trait loci (QTL) that segregate for clinical mastitis (CM) and milk yield (MY) on Bos taurus autosome 20 (BTA20) to determine whether both traits are affected by a single polymorphism (pleiotropy) or by multiple closely linked polymorphisms.

    2013-01-01

    This study presented a potentially useful alternative approach to ascertain the presence of subclinical and clinical mastitis in dairy cows using support vector machine (SVM) techniques. The proposed method detected mastitis in a cross-sectional representative sample of Holstein dairy cattle milked using an automatic milking system. The study used such suspected indicators of mastitis as lactation rank, milk yield, electrical conductivity, average milking duration, and control season as input data. The output variable was somatic cell counts obtained from milk samples collected monthly throughout the 15 months of the control period. Cattle were judged to be healthy or infected based on those somatic cell counts. This study undertook a detailed scrutiny of the SVM methodology, constructing and examining a model which showed 89% sensitivity, 92% specificity, and 50% error in mastitis detection. PMID:24574862

    Mastitis is one of the most prevalent and costly diseases in the dairy industry with losses attributable to reduced milk production, discarded milk, early culling, veterinary services, and labor costs. Typically, mastitis is an inflammation of the mammary gland most often, but not limited to, bacterial infection, and is characterized by the movement of leukocytes and serum proteins from the blood to the site of infection. It contributes to compromised milk quality and the potential spread of antimicrobial resistance if antibiotic treatment is not astutely applied. Despite the implementation of management practises and genetic selection approaches, bovine mastitis control continues to be inadequate. However, some novel genetic strategies have recently been demonstrated to reduce mastitis incidence by taking advantage of a cow's natural ability to make appropriate immune responses against invading pathogens. Specifically, dairy cattle with enhanced and balanced immune responses have a lower occurrence of disease, including mastitis, and they can be identified and selected for using the high immune response (HIR) technology. Enhanced immune responsiveness is also associated with improved response to vaccination, increased milk, and colostrum quality. Since immunity is an important fitness trait, beneficial associations with longevity and reproduction are also often noted. This review highlights the genetic regulation of the bovine immune system and its vital contributions to disease resistance. Genetic selection approaches currently used in the dairy industry to reduce the incidence of disease are reviewed, including the HIR technology, genomics to improve disease resistance or immune response, as well as the Immunity(+)™ sire line. Improving the overall immune responsiveness of cattle is expected to provide superior disease resistance, increasing animal welfare and food quality while maintaining favorable production levels to feed a growing population.

    Full Text Available In this investigation, some epidemiological studies were run on subclinical mastitis for totally 350 dairy cows of different breeds, ages and distributed in different villages in Assiut governorate, Assiut, Egypt, along a whole year (during the period from June 2006 till July 2007 through field screening surveys by using of the California mastitis test (CMT for each quarter milk sample followed by bacteriological examination to identify the major causative agents of intramammary infection (IMI. The dairy cows were differed from the breed point of view as 230 Holstein Friesian breed and 120 native breed. Also, they were differed from the age point of view as a group of 95 cows aged from 2 to 4 years old and another group of 255 cow aged from 5 to 8 years old. All dairy cows were apparently healthy with clinically sound udder secreting apparently normal milk. All the cows lived nearly under the same conditions of breeding from the habitat, hygiene and feeding systems. The obtained results revealed that 67 cows (19.14% had 80 infected quarters (5.71%. It was found that the most frequently major causative agents isolated were Staphylococcus aureus, Streptococcus agalactiae and Escherichia coli from the positive CMT samples with prevalence 52.5, 31.25 and 16.25%, respectively. With studying the breed factor, it was found Friesian breed was sensitive towards infection (20.43% at the cow level and 6.09% at the quarter level than of native breed (16.67% at the cow level and 5% at the quarter level. It was also noticed that the prevalence of subclinical mastitis in hot weather as during summer (9.14% at the cow level and 2.64% at the quarter level and during spring (4.86% at the cow level and 1.36% at the quarter level was higher than in cold weather as during winter (2% at the cow level and 0.64% at the quarter level and during autumn (3.14% at the cow level and 1.07% at the quarter level. In relation to age susceptibility, 5-8 years old cows (15.43% at the cow level and 4.36% at the quarter level were susceptible than those of 2-4 years (3.71% at the cow level and 1.36% at the quarter level. The degree of quarter attack according to positive CMT was varied from 35 quarters (2.50% showed degree (+++, to 45 ones (3.22% showed degree (++, to 120 ones (8.57% showed degree (+ and the rest (85.71% showed degree (-. The obtained results threw the light on the epidemiology of subclinical mastitis in Assiut villages and provided an importance of the CMT for diagnosis of subclinical mastitis due to it is a reliable, easy, rapid and cheap tool helping in diagnosis and controlling the disease because it directs attention to individual mammary quarter that is secreting milk of high somatic cell content (SCC. Programs for control of subclinical mastitis may be planned around the routine examination of all lactating cows, and consequently early treatment can be applied towards positive cases rapidly for preventing their conversion towards clinical form among dairy cows and for protecting the herd health, milk hygiene and consequently the consumer health.

    Full Text Available Milk production in Brazil is undoubtedly one of the most important Brazilian agroindustrial complex. Moves large sums of money, the dairy industry employs millions of the people, having potential to provide the domestic and foreign markets. Besides surpassing year by year the index production. The quality of milk is increasingly demanded by consumers and there are bonus programs for milk with low somatic cell counts, which reveal, indirectely, the udder sanity. Mastitis, the udder inflamation, is the main factor that substantially compromises the milk quality. Several methods can diagnose the incidence of subclinical mastitis in dairy herds. One these methods, the California Mastitis Test (CMT has as advantages being practical, low cost and the results are immediately available. The CMT method consists of adding the anionic neutral detergent to a milk sample in order to disrupt milk somatic cell membranes and release nucleic material. The viscousity formed by this reaction allows estimating the number of somatic cells (immunity cells presents in the milk. According to the degree of gelatinization obtained in this reaction, the interpretation of the scores varies from zero, no viscosity, to three crosses, highly viscous. This study was aimed to evaluate the CMT of eight dairy herds of different farms in Sao Paulo state, described by the letters A to H. The scores 1, 2 and 3 were considered positive for subclinical mastitis, while 0 was negative. The results were determined in relative frequency (%. It is evident that the herd D is the most affected by subclinical mastitis, because of the greater number of CMT positive (60%. This may be due to the mismanagement and poor conditions of milking. The properties C, F and G require greater attention, as the result of CMT could corroborate the presence of pathogenic microorganisms and infected cows can quickly transmit the infection to the healthy ones. Note that the farms A, B and H are the ones with the largest number of CMT negative, that is, with cows with better conditions of udder sanity. Over all it is found that CMT consists of an effective test for the detection of subclinical mastitis.

    Bilateral anterior glenohumeral dislocation is a rare occurrence. We present a case of bilateral anterior glenohumeral dislocation caused by a fall. The interest in publishing this case is that this is a clinical rarity with few cases reported in the literature. An 89-year-old female patient was brought to the emergency department after a fall, complaining of intense pain in both shoulders and inability to move them. Objective examination showed clinical signs giving the suspicion of bilateral anterior glenohumeral dislocation, which was confirmed by x-ray imaging. Both dislocations were successfully reduced in the emergency department using the modified Milch technique. When a synchronous and symmetrical force has acted on both shoulders and these are painful with significant functional limitation, the suspicion of bilateral glenohumeral dislocation is a differential diagnosis to be considered, even though it is rare.

    Full Text Available The purpose of this research was to evaluate the effects of evaporative cooling in freestall on mastitis occurrence, milk production, and composition, as well as cortisol, T3 (triiodothyronine, and T4 (thyroxin levels in lactating dairy cows. Twenty-eight multiparous cows averaging 70 ± 10 day postpartum were used in four treatments from January to March 2003. The treatments were: Day (cooling from 7:00 a.m. to 7:00 p.m.; Night (cooling from 7:00 p.m. to 7:00 a.m.; 24-hour (cooling 24-hour; and Control (no cooling. Wired cup test was used for clinical mastitis diagnosis, and the California Mastitis Test (CMT was used to identify subclinical mastitis. Blood and milk samples were taken weekly for microbiological and hormonal analyses. The cortisol levels were higher than normal values in all treatment groups, suggesting stress conditions, but T3 and T4 levels remained normal in all groups. The occurrence of subclinical mastitis was lower in Day and Night groups than in Control and 24-hour groups. Regarding the microbiological analyses, in all groups the isolation of Corynebacterium sp. from milk samples increased while negative coagulase staphylococci (CNS declined as etiological agents of subclinical mastitis. However, in Day and 24-hour groups, coagulase positive staphylococci (CPS increased mainly Staphylococcus aureus (49.8% and 47.7% respectively. The Night group showed a decrease in subclinical mastitis occurrences. Our data indicate that all animals subjected to treatments presented high levels of cortisol, indicating a stress condition. The Night treatment presented a reduction in microbial isolation, suggesting a reduced susceptibility to mastitis.

    2013-06-01

    This paper proposes and discusses a methodology to evaluate the performance of automated mastitis-detection systems with respect to their practical value on farm. The protocols are based on 3 on-farm requirements: (1) to detect cows with clinical mastitis promptly and accurately to enable timely and appropriate treatment, (2) to identify cows with high somatic cell count to manage bulk milk SCC levels, and (3) to report the mastitis infection status of cows at the end of lactation to support decisions on individual cow dry-cow therapy. Separate protocols for each requirement are proposed and discussed, including gold standards, evaluation tests, performance indicators, and performance targets. Aspects that require further research or clarification are identified. Actual field data are used as examples. Further debate is invited, the aim being to achieve international agreement on how to evaluate and report performance of different mastitis-detection technologies. Better performance information will allow farmers to compare different mastitis-detection systems sensibly and fairly before investing. Also, the use of evaluation protocols should help technology providers to refine current, or develop new, automated mastitis-detection systems. Such developments are likely to accelerate adoption of these systems, potentially leading to improved animal health, milk quality, and labor productivity. PMID:23548290

    Full Text Available Silent, or clinically nonfunctioning adenomas are morphologically heterogeneous group, characterized by positive immunoreactivity for one or more hormones classically secreted by normal pituitary cells but without clinical expression. Although in some occasions enhanced or changed secretory activity can develop over time. According to immunoreactivity they are divided into "silent" gonado-, cortico-, somato -, mammo – and thyrotropinomas, oncocytomas, «zero-cell» tumors. All types of "silent" adenomas have different biological activity, secretory capacity and outcomes in the postoperative period. This series of clinical cases shows more «aggressiveness», a higher risk of relapse for "silent" cortico- and somatotropinomas. Immunohistochemical analysis of residual tissue can be used to identify patients with high risk of recurrence, to develop optimal treatment and follow-up.

    2015-06-01

    Full Text Available Records of in vitro susceptibility tests performed between 1992 and 2011 were retrospectively reviewed in order to evaluate the dynamic profiles of possible changes in antimicrobial resistance of Staphylococcus spp. isolated from milk samples of cows with mastitis during two decades. The results of 2,430 isolates tested by disk diffusion technique for susceptibility to oxacillin, penicillin, ampicillin, cephalexin, norfloxacin, tetracycline, sulfazotrim, gentamicin, and neomycin were analysed. Comparisons were performed between the percentages of resistance to antimicrobials and their classes and also between the decades studied. Additionally, the possible tendency or changes in the behaviour of these pathogens against the major drugs used in the last two decades were evaluated using regression analysis. The highest rates of resistance (P<0.0001 were observed for the beta-lactams (34.3%, with exception of cephalexin (6.9%, and for the tetracyclines (28%. Similar resistance rates (7.6% to 15.7% were observed among the other drugs. Regression analysis showed a reduction in resistance to penicillin and ampicillin throughout the period, whilst for oxacillin and neomycin a decrease in the resistance was observed during the first decade, followed by an increase. A trend towards decreased resistance was found for sulfazotrim, whereas for the other antimicrobials no decrease was observed. The results indicated no trend towards increased resistance for most antimicrobials tested. Nevertheless, it is necessary to monitor the resistance patterns of these pathogens in order to save these drugs as a therapeutic reserve

    Full Text Available External cervical resorption (ECR is an invasive type of resorption that begins below the gingival epithelium and affects mineralized tissues, e.g., cementum and dentin. Most authors refer to dental trauma, whitening agents, and orthodontic treatment as etiologic factors of ECR; clinical diagnosis is performed via inspection of the gingival groove and margin. In this scenario, cone beam computed tomography has become a highly valuable ancillary method, as it allows to assess the proximity between the resorption and the pulp cavity, and thus, plan treatment. This article describes, in the form of a clinical case report, the diagnosis and treatment of a case of ECR affecting tooth no. 11, classified as Class III according to Heitersay’s classification. Surgical approach, restoration and clinical follow-up over 2-years of follow-up are described. In view of the clinical and radiographic findings observed during follow-up, it can be concluded that treatment was successful in healing periodontal tissues, suggesting a good prognosis.

    Full Text Available The aim of this research was to measure the relationship of the pH value to the somatic cell count as a parameter of sub clinical mastitis detection. Two hundreds quarter milk samples were used in this research and the test (the pH value, IPB-1 mastitis test and Breed method was done in parallel way. The results showed that 152 samples from 200 samples (76% tested with Breed method came from the herds which suffered from sub-clinical mastitis and with IPB-1 test showed that 145 (72.5% of the samples had positive reaction. Using pH meter, it showed that 44 samples (22 % had pH > 6.75, presumed suffered from sub-clinical mastitis and 2 samples (1% showed pH < 6.30 (6.25 and 6.28. At the same time, these two samples showed a negative reaction with IPB-1 test and had somatic cell count of 360,000/ml and 280,000/ml, each. It also showed that there was a close relationship between pH value and IPB-1 test. The conclusion of this research was that the measurement of pH value was not a sensitive method for detecting sub-clinical mastitis.

Abstract in english The effect of immunization with Escherichia coli J5 vaccine in the pre-partum on the occurrence of mastitis and milk production in crossbred dairy cows was evaluated. Ninety-three cows were used as follows: forty-three were vaccinated and fifty cows were unvaccinated. For the production analysis, da [...] ta and CCS were used in a completely randomized split-plot system. CCS data and duration of clinical cases of mastitis were transformed into Log10CCS. For the CSS averages and duration of clinical cases we used the t test. For comparisons of means of recurrences of clinical cases we used the Mann-Whitney test. For frequency of subclinical mastitis organisms and we used the chi-square test. The interaction of these variables was analyzed using the McNemar test. There was no reduction in the prevalence of infections caused by coliforms between drying-off and parturition in both groups. The total duration of clinical mastitis in animals with clinical mastitis was lower in vaccinated than unvaccinated cows. The number of clinical episodes and intensity of clinical cases did not differ between groups. The prevalence of animals with subclinical mastitis at postpartum and somatic cell count (SCC) in the first 100 days of lactation was lower in vaccinated than unvaccinated cows. However, there was no difference in milk production between groups. Vaccination of cows with E. coli J5 improves mammary gland health by reducing the prevalence of animals with subclinical mastitis at postpartum, as well as the duration of the clinical cases of mastitis and SCC in the first 100 days of lactation.

    A retrospective study is reported on the clinical outcome of six patients with isovaleric acidemia (IVA) diagnosed during the last 20 years at the Metabolic Unit of Hacettepe University Children's Hospital. IVA is only one of many inborn errors of metabolism that may have an acute or a late, intermittent presentation. Generally, the diagnosis cannot be made by clinical or routine clinical chemical investigations, although the odor of "sweaty feet" is a presenting symptom. An unusual urinary odor, which was present in all of our patients, should lead to a thorough screening for organic acidemia at any age. Here, we have reported six patients with IVA. Two pairs were siblings. All, except one patient, had positive family history of sibling deaths and all parents were related. In our series, only two patients presented during the neonatal period and both died during the acute crisis. The other four patients presented after the neonatal period and were categorized as having a chronic intermittent form of IVA. Two cases showed normal development despite repeated metabolic decompensations; one patient was diagnosed during the first attack, but he was mentally and motor retarded. The other one died during the metabolic crisis. The presented cases illustrate that IVA can be managed successfully once the diagnosis is made. But lack of early recognition may lead to severe psychomotor retardation or death. PMID:9673537

    The development and test of detection models for oestrus and mastitis in dairy cows is described in a PhD thesis that was defended in Wageningen on June 5, 2000. These models were based on sensors for milk yield, milk temperature, electrical conductivity of milk, and cow activity and concentrate intake, and on combined processing of the sensor data. The models alert farmers to cows that need attention, because of possible oestrus or mastitis. A first detection model for cows, milked twice a day, was based on time series models for the sensor variables. A time series model describes the dependence between successive observations. The parameters of the time series models were fitted on-line for each cow after each milking by means of a Kalman filter, a mathematical method to estimate the state of a system on-line. The Kalman filter gives the best estimate of the current state of a system based on all preceding observations. This model was tested for 2 years on two experimental farms, and under field conditions on four farms over several years. A second detection model, for cow milked in an automatic milking system (AMS), was based on a generalization of the first model. Two data sets (one small, one large) were used for testing. The results for oestrus detection were good for both models. The results for mastitis detection were varying (in some cases good, in other cases moderate). Fuzzy logic was used to classify mastitis and oestrus alerts with both detection models, to reduce the number of false positive alerts. Fuzzy logic makes approximate reasoning possible, where statements can be partly true or false. Input for the fuzzy logic model were alerts from the detection models and additional information. The number of false positive alerts decreased considerably, while the number of detected cases remained at the same level. These models make automated detection possible in practice. PMID:11233511

The study was conducted through a simulation in the computer system 'CU$TO MASTITE' ('MASTITIS CO$T'), considering dairy cattle with 50; 100 and [...] 150 lactating cows. Monitoring expenses (culture and antibiogram, CCST and CCSI), pre and post dipping, vaccination, treatment of dry cows and milking maintenance, were considered as prevention. The treatments with clinical cases, which had a 7% percentage of lactating cows were considered as curative measures. The impact of mastitis was estimated as the total of losses plus expenses with prevention and the treatments of clinical cases. The increase of the production scale resulted in a lower economic impact of mastitis per lactating cow. When the effect of the production scale was analyzed, the losses with milk disposal, curative treatment of clinically affectedanimals and a decrease in milk production were the factors that most affected the economic impact, in a descending order. Expenses with preventive treatment accounted for, at maximum, 11.7% of the economic impact, which demonstrates advantages of investing on that practice because it will contribute significantly for the reduction of the economic impact caused by mastitis

    Bovine mastitis is the most common and costly dairy cattle disease. Mastitis is most frequently caused by bacterial species, and to ensure optimal treatment and control strategies, proper quality assured diagnosis and identification of the causative agent is important. With the aim to assess the capacity to isolate and identify mastitis pathogens at veterinary clinics, an external quality assurance system (EQAS) was annually (from 2006 to 2011) provided for the identification of mastitis pathogens. This study presents the setup of the proficiency test and the obtained results that enabled the organizers to pinpoint areas for improvement and thereby to assist veterinary practices at strengthening their mastitis diagnostics. The proficiency test consisted of 15 milk samples spiked with a pure culture of a mastitis pathogen and distributed to veterinary practices for identification. Applying an internal quality control strain, i.e. including the same strain of Streptococcus agalactiae in all iterations of the proficiency test, served to gauge the bias caused by the year-to-year variation in the selection of test strains. A total of 73% of all uploaded results over the years were correct, with the internal quality control strain exhibiting a statistically significant ascending trend from 54% correct identifications in 2006 to 91% in 2011 (p-value=0.0082; n=13). Even if specifics were not recorded as regards the laboratory methods employed at the veterinary clinics for identification of mastitis pathogens, the results from this study indicate that the practices' application of basic biochemical analyses in this context could be optimized. In addition, dissemination of information on new methods and updated nomenclature appeared to be an area which future efforts with advantage could aim at. PMID:23199580

    Caudal regression syndrome is an uncommon congenital malformation that includes a wide spectrum of clinical presentations. Characterised by caudal musculoskeletal compromise, it can be associated to neurological, gastrointestinal, renal and genitourinary defects. Although the specific aetiology has not been clarified, it has been associated with the presence of maternal diabetes and mutations in homeobox gene HBLX9. Its diagnosis is based on a good prenatal ultrasound detection, detailed physical examination, and post-natal imaging study using radiography and magnetic resonance. Caudal regression syndrome requires multidisciplinary management, and it seems that good metabolic control of gestational diabetes constitutes the best preventive measure available. We present the clinical case and images of a male term newborn, born to a pregestational diabetic mother with poor metabolic control and a prenatal ultrasound diagnosis of lumbar spine, iliac bones and lower limbs malformation. Born in good conditions, the diagnosis was confirmed using X-rays and magnetic resonance. PMID:26455704

    Full Text Available Abstract Over the past 20 years, several proton beam treatment programs have been implemented throughout the United States. Increasingly, the number of new programs under development is growing. Proton beam therapy has the potential for improving tumor control and survival through dose escalation. It also has potential for reducing harm to normal organs through dose reduction. However, proton beam therapy is more costly than conventional x-ray therapy. This increased cost may be offset by improved function, improved quality of life, and reduced costs related to treating the late effects of therapy. Clinical research opportunities are abundant to determine which patients will gain the most benefit from proton beam therapy. We review the clinical case for proton beam therapy. Summary sentence Proton beam therapy is a technically advanced and promising form of radiation therapy.

    1994-09-01

    The most common surgery performed in our clinic with the CO2 laser is the cutting and vaporization of neoplasms associated with the head and neck, in particular, the squamous cell carcinoma in the cat. A majority of the tumors are malignant and 50% are metastatic at the time of presentation for surgery. Experience has taught us that early detection and removal with the CO2 laser affords the best prognosis. To date, roughly 100 cases have been treated with the CO2 laser. The success rate in the dog is not as rewarding as in the cat. Most cases were done with 5 - 10 watts of power continuous or pulsed wave, using a 125 mm or 50 mm handpiece. The laser beam was focused or defocused to adjust for cutting, vaporization, and coagulation. No post-op care of the wounds was recommended. Other small neoplasms in and around the ears, head, and neck can also be removed easily with the CO2 laser.

    Granulomatous lobular mastitis (GLM) is an uncommon condition that typically occurs in parous, reproductive-aged women and can simulate malignancy on the basis of clinical and imaging features. A distinctive histologic pattern termed cystic neutrophilic granulomatous mastitis (CNGM) is seen in some cases of GLM and has been associated with Corynebacterium infection. We sought to further characterize the clinical, imaging, and histopathologic features of CNGM by studying 12 cases and attempted to establish the relationship of this disease with Corynebacterium infection. Patients were women ranging in age from 25 to 49 years (median: 34 y), and all presented with a palpable mass that was painful in half of the cases. In 2 of 9 cases, imaging was highly suspicious for malignancy (BI-RADS 5). CNGM was characterized by lobulocentric granulomas with mixed inflammation and clear vacuoles lined by neutrophils within granulomas. Gram-positive bacilli were identified in 5/12 cases. In 4 patients, the disease process worsened after the diagnostic core biopsy, with the development of a draining sinus in 2 cases. No growth of bacteria was seen in any microbial cultures. No bacterial DNA was identified by 16S rDNA polymerase chain reaction for 1 case that showed gram-positive bacilli on histology. Patients were treated with variable combinations of surgery, antibiotics, and steroids. The time to significant resolution of symptoms ranged from 2 weeks to 6 months. Similar to other forms of GLM, CNGM can mimic malignancy clinically and on imaging. When encountered in a needle core biopsy sample, recognition of the characteristic histologic pattern and its possible association with Corynebacterium infection can help guide treatment.

    Full Text Available Abstract Background Mastitis is the most important disease in dairy cows and it causes significant lost of profit to producers. Identification of the genes, and their variants, involved in innate immune responses is essential for the understanding of this inflammatory disease and to identify potential genetic markers for resistance to mastitis. The progeny of dairy cows would benefit from receiving favourable alleles that support greater resistance to infection, thus reducing antibiotic use. This study aims to identify a key gene in the innate immune response to mastitis, led us to evaluate its genetic association with somatic cell score (SCS, which is an indicator of clinical mastitis, and to evaluate its impact on other traits related to milk production. Results The osteopontin transcript (SPP1 was identified in the somatic cells from cows experimentally infected with Escherichia coli. By selecting bulls with extreme estimated breeding values (EBVs for SCS, which is an indicator of mammary gland health, four DNA polymorphisms in the SPP1 genomic sequence were found. Statistical analysis revealed that the SNP SPP1c.-1301G>A has an impact on EBV for SCS (P SPP1c.-1251C>T, SPP1c.-430G>A, and SPP1c.*40A>C have an impact on SCS whereas SPP1c.-1301G>A has an effect on the EBVs for milk yield (second and third lactations, fat and protein percentages (all three lactations. Analysis revealed statistically significant differences between haplotype groups at a comparison-wise level with sire EBVS for SCS for the first (P = 0.012, second (P P Conclusion This study reports the link between DNA polymorphisms of SPP1, the number of milk immune cells and, potentially, the susceptibility to mastitis. These SNPs were identified by in silico search to be located in transcription factor recognition sites which factors are presumably involved in the Th1 immune response and in the Th2 regulation pathway. Indeed, one SNP abolished the SP1 recognition site, whereas another SNP affected the transcription binding factor IKAROS. All together, these findings support the genetic potential of these variants in terms of selection for the improvement of mastitis resistance in dairy cows.

    The objective of this study was to investigate the association between mastitis events occurring during the previous lactation, the dry period, and the peripartum period on the incidence of early lactation mastitis in cows receiving ceftiofur hydrochloride or penicillin dihydrostreptomycin as intramammary dry cow antibiotic therapy. Cows (n=402) from 2 large dairy farms in Central Florida were enrolled in the study at the time of dry-off processing and were randomly assigned to 1 of 2 dry cow therapies: ceftiofur hydrochloride or penicillin dihydrostreptomycin. Composite milk samples were collected at dry-off and after calving for bacteriological examination and somatic cell count. Peripartal health disorders were monitored during the first 30 d of lactation and included calving difficulty, metritis, ketosis, and left displaced abomasum. Milk production and individual somatic cell scores (SCS) were recorded monthly by the Dairy Herd Improvement Association. The main outcome variables were the risk of clinical mastitis during the first 30 and 60 d of lactation, and the risk of subclinical mastitis at the first 2 monthly Dairy Herd Improvement Association tests after calving (up to 70 d in milk). Additionally, the SCS and the presence of mastitis pathogens in milk at dry-off and at calving were analyzed. Explanatory variables consisted of events occurring during the previous lactation, at dry-off and during the dry period, at calving, and within the first 30 d after calving. Multiple events occurring during the previous lactation had a significant effect on the incidence of mastitis in the subsequent lactation. These events included low milk yield, intermediate lactation length, clinical mastitis, and lactation SCS average. Similarly, intramammary infections with environmental bacteria at dry-off increased the chances of clinical mastitis the first month after calving. Dry-off therapy had a significant effect on mastitis incidence; cows treated with ceftiofur hydrochloride had lower odds of having clinical and subclinical mastitis in the subsequent early lactation compared with cows treated with penicillin dihydrostreptomycin.

    Full Text Available The annual incidence of adult-onset Still's disease (AOSD worldwide is 0.16 cases per 100,000 persons. Its leading symptoms are joint involvement, fever, skin rash, and neutrophilic leukocytosis in the absence of rheumatoid factor and anticyclic citrullinated peptide antibodies in serum and synovial fluid. In its initial stage, there may be monoarthritis more commonly of the wrist, hip, or knee. Then the lesion assumes the pattern of oligo- or polyarthritis. Musculoskeletal involvement appearing as arthralgia, arthritis, and myalgia is noted in all patients. In the majority of patients, articular involvement progresses and destructive polyarthritis develops. Symmetric involvement of the carpophalangeal and distal interphalangeal joints is frequently detected. Skin lesion manifests itself as maculopapular or roseolous rashes on the chest, back, shoulders, occasionally on the legs, or in the areas of mechanical irritation. A sore throat with the signs of pharyngitis is a characteristic early symptom of the disease. There may be involvements of the liver, cardiovascular system, lung, as well as lymphadenopathy, or splenomegaly. The chronic course of the disease is more frequently noted.The paper describes two cases of AOSD. One case demonstrates that the physician has no experience in diagnosing and managing patients with AOSD, resulting in the misinterpretation of the increase in disease activity when the subclinical doses of methotrexate (MT are used, which has been regarded as a therapeutic complication. The use of the adequate dose of MT could achieve a clinical and laboratory remission and discontinue glucocorticoids (GC.In the other case of recurrent AOSD and mild clinical symptoms, the unreasonable use of high GC doses gave rise to adverse reactions.

    Full Text Available The prevalence of caprine subclinical mastitis in Mymensingh area was assessed by California Mastitis Test (CMT. Milk samples were also analyzed for the isolation and identification of bacterial agents that might be associated with caprine subclinical mastitis including their antibiotic sensitivity pattern against commonly used antibiotics. In addition, the influence of certain risk factors such as age of animal, parity, length of lactation period, type of farming system and type of housing floor, on the prevalence of caprine subclinical mastitis was also evaluated. Milk samples were collected from 59 goats (113 udder halves. The overall prevalence of caprine subclinical mastitis as determined by CMT was 18.64%. On an udder half basis the prevalence was 15.04%. Certain risk factors associated with caprine subclinical mastitis were identified. The prevalence was higher in older animals, with greater parity and longer lactation period. The prevalence was also higher in farms where goats were raised under traditional farming system with earthen floors. The predominant bacterial species isolated from milk that were collected from the subclinical mastitis positive cases were Staphylococcus aureus, S. epidermidis and Bacillus subtilis, that showed various degrees of sensitivity to the antibiotics used in the study.

    The study purpose was to validate Petrifilms(TM) (3M Microbiology, 2005) against standard culture methods in the diagnosis of bovine mastitis organisms in Kenya. On 128 smallholder dairy cattle farms in Kenya, between June 21, 2010 and August 31, 2010, milk samples from 269 cows that were positive on California Mastitis Test (CMT) were cultured using standard laboratory culture methods and Petrifilms(TM) (Aerobic Count and Coliform Count -3M Microbiology, 2005), and results were compared. Staphylococcus aureus was the most common bacterium isolated (73 % of samples). Clinical mastitis was found in only three cows, and there were only two Gram-negative isolates, making it impossible to examine the agreement between the two tests for Gram-negative- or clinical mastitis samples. The observed agreement between the standard culture and Petrifilm(TM) (3M Microbiology, 2005) results for Gram-positive isolates was 85 %, and there was fair agreement beyond that expected due to chance alone, with a kappa (κ) of 0.38. Using culture results as a gold standard, the Petrifilms(TM) had a sensitivity of 90 % for Gram-positive samples and specificity of 51 %. With 87 % of CMT-positive samples resulting in Gram-positive pathogens cultured, there was a positive predictive value of 93 % and a negative predictive value of 43 %. Petrifilms(TM) should be considered for culture of mastitis organisms in developing countries, especially when Gram-positive bacteria are expected. PMID:23108587

    Staphylococcus aureus is recognized worldwide as a pathogen causing many serious diseases in humans and animals, and is the most common aetiological agent of clinical and subclinical bovine mastitis. The importance of evaluating the combination of S. aureus virulence factors has been emphasized both in human and veterinary medicine, and knowledge about the genetic variability within different S. aureus populations would help in the design of efficient treatments. The aim of the present study was to determine the genetic profiles of S. aureus strains isolated from milk of cows suffering from clinical and subclinical mastitis in Belgium. The presence of about forty virulence-associated genes was investigated by specific polymerase chain reaction (PCR) amplification. A high number of genotypic subtypes were observed, demonstrating further the large variation in the presence of virulence genes in S. aureus isolates and the considerable diversity of strains populations that are able to cause mastitis in cows. In accordance with other studies, we showed that some genes are associated with mastitis-causing S. aureus isolates, whereas others are absent or rarely present. We also further highlighted the presence of conserved gene combinations, namely the enterotoxigenic egc-cluster and the bovine pathogenicity island SaPIbov. Importantly, the presence of isolates carrying genes coding for toxins involved in important human infections makes the milk of cows with mastitis a potential reservoir for these toxins, and therefore a potential danger in human health, which strengthens the importance to consider raw milk consumption and its processing very carefully.

    Cleidocranial dysplasia (CCD) is an autosomal-dominant disorder that occurs due to mutations in the Cbfa 1 gene, also called Runx 2, located on the short arm of chromosome 6, affecting osteoblast skeletal-specific bones that have intramembranous ossification. This condition is characterized by hypoplastic clavicles, short stature, and great clinical significance in the stomatognathic complex, with involvement of facial bones, changes in the eruption patterns, including multiple supernumerary and retained teeth. This study reports six subjects of the same family with CCD identified in the Dentistry Clinic of Oral Diagnosis Department, Universidade Paulista, Campus Sorocaba, Sao Paulo State, Brazil. All cases had clinical and radiographic aspects of this important condition, such as short stature, hypertelorism, severe mobility of the shoulders, and supernumerary and retained teeth. Due to the rare incidence and phenotypic manifestations, CCD can be easily misdiagnosed. The oral commitments are one of the main (functional and aesthetic) causes of complaints in these subjects; and a dentist must establish the diagnosis as early as possible, followed by behaviors and practices that can minimize harmful manifestations of the syndrome and improve health associated with oral and multidisciplinary integration offering improvements in quality of life of these subjects.

  20. Utilization of zinc methionine supplementation in Friesian cows: somatic cell count in milk and mastitis

    International Nuclear Information System (INIS)

    Full text: Two hundreds and forty lactating Friesian cows on the 1st to 8th of lactation and different stages of lactation were used to study some factors affecting on somatic cell count and its effects on milk yield and composition. Also, 12 normal cows, 15 subclinical and 15 clinical mastitis cows were used to study the effect of zinc methionine supplementation on somatic cell count and mastitis. Cows were divided into three similar groups, the first groups was unsupplemented, while the second and third groups were supplemented with 5 and 10 gm zinc methionine / head / day, respectively. Subclinical and clinical mastitis cows were intramammary injected by antibiotic Gentamast (Gentamicin 100 mg) till complete recovery. The obtained results showed that winter season showed significantly (P < 0.05) the highest somatic cell count followed by summer season, while the lowest value was in autumn season. Somatic cell count tended to decrease with the progress of lactation up to the peak period and increased significantly (P < 0.05) thereafter and also with the progress number of lactation. The percentages of normal, subclinical and clinical mastitis cows were 77.71, 15.82 and 6.46%, respectively. Milk yield and composition and its output decreased significantly (P < 0.05) with increasing somatic cell count. Zinc methionine supplementation resulted in significant (P < 0.05) decrease in somatic cell count in milk. Zinc methionine supplementation for subclinical and clinical mastitis cows led to significant decrease (P < 0.05) on somatic cell count, electrical conductivity, recovery time and the cost of therapy compared with unsupplemented group. It could be concluded that increasing somatic cell count decreased milk yield and composition. Zinc methionine supplementation at the level of 5 g per head daily to lactating Friesian cows reduced somatic cell count in milk, recovery time and therapy cost of mastitis. (author)

    Full Text Available An outbreak of coliform mastitis is described in a dairy herd from the State of Rio de Janeiro, Brazil. During a four-month period 14 fatal cases of Klebsiella pneumoniae-related mastitis were observed in a herd of 104 lactating cows. The symptoms included peracute enterotoxemia in which the cows died 6 to 12 h after the detection of mastitis by CMT. Staphylococcus aureus and Streptococcus agalactiae Streptococcus agalactiae were also isolated although could not be associated with cases of acute fatal mastitis. Milking practices were also evaluated. The milking machine was being used correctly and adequate precautions for hygiene and pre-milking and post-milking teat dipping were used. The organism was sensitive to gentamicin. Therapy for acute toxic mastitis required early action for the treatment of infections, involving corticosteroids and fluid therapy. The use of a Klebsiella vaccine produced from the microorganisms isolated from the herd, associated with hygiene measures, resulted in the control of the outbreak.

    2014-06-01

    Syncope is defined as a transient, self-limiting loss of consciousness and postural tone due to transient global cerebral hypoperfusion. After syncope the following questions have to be answered: was it a syncopal episode, has the etiological diagnosis been determined, are there data suggestive of a high risk of cardiovascular events or death and what are the therapeutic options? Therefore, a standardized diagnostic work-up is necessary. This diagnostic work-up with differential diagnostic considerations is given for three clinical cases: a 52-year-old man experienced syncope while driving a car and on the morning of the same day syncope had previously occurred while in a standing position. The initial cardiological and neurological evaluation revealed no pathological findings but after implantation of a loop recorder a further syncope with a sinus arrest of 17s occurred 1 year later. The patient received a single chamber pacemaker. The second case is a 79-year-old female with Parkinson's disease for many years and a primary autonomic dysfunction leading to dizziness and syncope due to pronounced blood pressure fluctuations with hypertensive and hypotensive phases. The last patient is a 22-year-old female with postural orthostatic tachycardia syndrome and recurrent syncope. The diagnostic evaluation and treatment proved to be difficult. PMID:24898287

    The study aimed to use infrared thermography (IRT) to evaluate the changes in udder surface temperature after induction of Escherichia coli mastitis in the right hind quarter. Over a time period of 24?h before to 24?h post-inoculation, thermograms of both hind quarters were taken every 2?h to determine maximum (Tmax) and average (Tavg) temperatures. Differences in both maximum and average temperatures (DTmax and DTavg) were calculated, as well as temperature differences between both hind quarters. All cows developed signs of clinical mastitis with a significant increase in DTmax and DTavg with Tmax at 13?h post-inoculation for the (non-infected) left hind quarters. The results demonstrate that detection of mastitis using IRT is possible if the interval between examinations does not exceed 2?h. PMID:25957921

  20. Inflammatory mediators in mastitis and lactation insufficiency.

    Science.gov (United States)

    Ingman, Wendy V; Glynn, Danielle J; Hutchinson, Mark R

    2014-07-01

    Mastitis is a common inflammatory disease during lactation that causes reduced milk supply. A growing body of evidence challenges the central role of pathogenic bacteria in mastitis, with disease severity associated with markers of inflammation rather than infection. Inflammation in the mammary gland may be triggered by microbe-associated molecular patterns (MAMPs) as well as danger-associated molecular patterns (DAMPs) binding to pattern recognition receptors such as the toll-like receptors (TLRs) on the surface of mammary epithelial cells and local immune cell populations. Activation of the TLR4 signalling pathway and downstream nuclear factor kappa B (NFkB) is critical to mediating local mammary gland inflammation and systemic immune responses in mouse models of mastitis. However, activation of NFkB also induces epithelial cell apoptosis and reduced milk protein synthesis, suggesting that inflammatory mediators activated during mastitis promote partial involution. Perturbed milk flow, maternal stress and genetic predisposition are significant risk factors for mastitis, and could lead to a heightened TLR4-mediated inflammatory response, resulting in increased susceptibility and severity of mastitis disease in the context of low MAMP abundance. Therefore, heightened host inflammatory signalling may act in concert with pathogenic or commensal bacterial species to cause both the inflammation associated with mastitis and lactation insufficiency. Here, we present an alternate paradigm to the widely held notion that breast inflammation is driven principally by infectious bacterial pathogens, and suggest there may be other therapeutic strategies, apart from the currently utilised antimicrobial agents, that could be employed to prevent and treat mastitis in women.

    Lupus mastitis is a form of lupus profundus that is seen in patients with systemic lupus erythematosus. It usually presents as a swelling (or swellings) in the breasts, with or without pain. The condition is recurrent and progresses along with the underlying disease, with fat necrosis, calcification, fibrosis, scarring, and breast atrophy. Lupus mastitis is often confused with malignancy and lymphoma and, in our part of the world, with tuberculosis. Confusion is especially likely when it occu...

    IgG4-related disease (IgG4-RD) is characterised by high serum concentrations of IgG4, dense lymphoplasmacytic infiltrates, storiform fibrosis and increased IgG4-positive plasma cells in tissues. This systemic disease occurs in various organs metachronously, but IgG4-related mastitis appears extremely rare. We report a case of IgG4-related mastitis, radiologically considered to represent breast cancer mainly composed of intraductal component and requiring histological differentiation from mucosa-associated lymphoid tissue (MALT) lymphoma. The breast mass disappeared with steroid therapy. When patients have a breast mass, regardless of the presence or absence of IgG4-RD, IgG4-related mastitis should be considered in addition to breast cancer. If histological findings show dense lymphoplasmacytic infiltrates, IgG4-related mastitis should be suspected in addition to malignant lymphoma, and lack of monoclonality should be confirmed. To avoid unnecessary surgery or chemotherapy, knowledge and accurate diagnosis of the entity of IgG4-related mastitis is necessary. PMID:27009197

    Full Text Available The present study was designed to determine the prevalence of different types of mastitis in camels in U.A.E. and to identify the causative microorganisms and their sensitivity to different antimicrobial agents. From 162 lactating she-camels, 630 milk samples were collected from different cities in Abu Dhabi Emirate/UAE. The overall prevalence of mastitis was 18.52% (7.94% on quarter basis, the prevalence of clinical and sub clinical mastitis was found to be 24.70% and 11.67% on animal basis, respectively; it being 9.70% and 5.86% on quarter basis, respectively. The hind quarters were more frequently affected than the fore quarters. Bacteriological examination of milk samples revealed that Staphylococcus was the chief etiological agents both in clinical and sub clinical mastitis (41.67% in camels, followed by Streptococcus spp. (21.67%, Enterobacter spp. (15.00%, C. pyogenes (10.00%, Micrococcus spp. (5.00%, Pasteurells spp. (5.00% and Pseudomonas aeruginosa (1.66%. Most of the Staphylococcus spp., Streptococcus spp. and C. pyogenes strains were sensitive to carbenicillin, gentamycin, kanamycin, and erythromycin, but resistant to colistin and sulphamethoxazole. Other pathogens like Enterobacter, Micrococcus, Pasteurella spp. and Ps. aeuroginosa isolates showed variable sensitivities to the antimicrobials.

    Full Text Available Introduction: In this environment, previous workers have reported on the challenges of managing large sized ameloblastoma of the jaws with less than adequate facilities. The aim of this review is to present the management of 68 cases of ameloblastoma with emphasis on surgical care. Materials and Methods: Retrospective survey of case notes of patients with histopathologic diagnosis of ameloblastoma (using the criteria of Barnes et al., 2005 seen between January 2006 and August 2010 at the Maxillofacial Unit, Ahmadu Bello University Teaching Hospital, Shika-Zaria, Nigeria was undertaken. Data collected includes histopathological diagnosis, age, gender, clinical information on site of lesion, form of intubation and surgical procedure performed. Results: Out of 94 patients, 68 with histological diagnosis of ameloblastoma (59 mandibular and 9 maxillary were operated within the study period. The remainder (26 was not treated in hospital. Among 68 patients treated, more were males (38 than females (30, giving a male to female ratio of 1.3:1. The age range was between 14 and 74 years (mean-standard deviation. The duration of the symptoms ranged from 7 months to 24 years, most were follicular ameloblastoma (n = 13 followed by acanthomatous type (n = 7. Endotracheal intubation was the most common (n = 55 followed by fiber optic laryngoscopy (n = 8. The surgical approach most used was extended Risdon with intraoral (n = 24 followed by extended Risdon with lip split and intraoral (n = 17. Segmental resection (en block formed the bulk of our procedures (n = 22 followed by subtotal mandibulectomy (n = 16. Conclusion: The treatment of ameloblastoma remains controversial. Its destructive nature has left patients with wide defects difficult to reconstruct.

    Dengue is an infectious disease caused by a flavivirus, with four serotypes, transmitted by the mosquito Aedes aegypti. In Mexico it is a public health problem, especially in the region of central and southeast of the country. The disease can be asymptomatic or present serious forms and even death. It is confirmed by detection of the NS1 Antigen; IgM antibodies, polymerase chain reaction and virus isolation. The vertical transmission to de newborn has been little studied. 7 cases in neonates from November to December 2011 are reported. All patients were male, obtained by caesarean section between 34 and 40 weeks of gestation, whose mothers were enrolled with fever and symptoms associated with dengue disease and serology positive for dengue. Six with positive AgNS1 and one positive IgM; one mother died. All the newborns had positive serology for dengue, 4 with positive AgNS1 and 3 positive IgM. The clinical features of the newborn ranged from asymptomatic to one serious dengue fever, shock and hemorrhage. The symptomatic 6 attended with thrombocytopenia, changes in temperature and unspecific disturbance. The severity of mothers conditioned disrepair product at birth, but not with subsequent gravity of the new born. Vertical trasmission of dengue should be suspected in risk areas, to maintain vigilance and to give early treatment. Also is neccesary promote the realization of specific diagnostic and therapeutic guidelines to the neonatal period. PMID:26233977

    Silver ions act as a powerful, broad-spectrum antimicrobial agent and are known to kill over 650 different kinds of pathogens. We investigated the protein expression pattern and identity after silver ion treatment in Escherichia coli and Staphylococcus aureus, which are primarily responsible for the majority of bovine mastitis cases using proteomics. Two-dimensional electrophoresis showed that silver ion treatment significantly reduced 5 spot's density in E. coli and S. aureus, respectively. We identified 10 proteins (alkyl hydroperoxide reductase C22 subunit, phosphoglucomutase, fructose-1-phosphate kinase, putative carbamoyl transferase, alpha-galactosidase, carbamate kinase, ornithine transcarbamoylase, fumarate hydratase class II, alcohol dehydrogenase, and conserved hypothetical protein) by matrix-assisted laser desorption ionization time of flight (MALDI-TOF). These results demonstrated that silver ions have bactericidal effects through energy deprivation, inhibition of DNA replication, and accumulation of oxidants in bovine mastitis pathogens and suggested that silver ions can be applied for the treatment of bovine mastitis.

    Prototheca sp., a colourless algae, is quite common in dairy environments, particularly in wet areas contaminated with manure. The main purpose of this paper is to describe an outbreak of clinical bovine mastitis in an 86-cow dairy herd in the State of So Paulo, Brazil. Prototheca sp., an achlorophyllous algae, were isolated on blood agar (incubated for 24 h at 37 degrees C) from 11 quarters of seven lactating Holstein cows, and from one quarter of a cow at the end of the dry period. Treatments were applied, but there was only a microbiological cure, not a functional one. Diagnosis of Prototheca sp. in any of the cows in the herd indicates a herd problem. Infected animals usually have markedly reduced milk production and granulomatous changes often occur in the mammary gland. All sources of contact between the teat ends and drainage water or damp areas should be corrected. An all-out effort for strict sanitation, including during milking, should be made so that the teat ends will not become contaminated. PMID:8794693

    A project implemented from 2003 to 2005 trained women in Chitwan District, Nepal, in hygienic dairy production using a process of social mobilization. The aim of this research was to assess if the prevalence of mastitis in water buffalo in the households of women who were trained was lower one year after training than in untrained households, if the training influenced knowledge and practices for the prevention or control of mastitis, and if these practices and knowledge were associated with a lower prevalence of mastitis. A total of 202 households from Eastern and Western Chitwan District were included in the study. Of these, 60 households had participated in the project and 142 had not. Milk samples were collected from 129 households (33 project households and 96 non-project households). Clinical mastitis was determined using visual inspection of udders and detection of macroscopic clots and flakes in milk. The California Mastitis Test was used to diagnose sub-clinical mastitis from milk samples, and the IDEXX SNAP test to identify the presence of tetracycline residues. The prevalence of mastitis in trained households (39.4%) was 43.78% of that in untrained households (60.4%), lower but not significantly so (p=0.08, 95% CI 0.17-1.12). Thirteen indicators of knowledge or practice for the control or prevention of mastitis were more likely to occur in trained households, four significantly so (not consuming milk from sick buffalo (p=0.001), using soap to wash hands before milking (p=0.001), discarding milk after antibiotic usage (p=0.01), and choosing appropriate flooring for their livestock (p=0.03)). Trained households that discarded milk from sick buffalo were 2.96 times more likely to have at least one animal with mastitis in the household (p=0.03, 95% CI 1.15-7.65). Trained households that knew to wash buffalos' teats after milking were less likely (OR 0.25) to have mastitis in their herd (p=0.02, 95% CI 0.08-0.80). Of the 138 buffalos tested, only one tested positive for tetracycline residues. PMID:20655119

    Mycoplasma bovis causes mastitis in dairy cows and is associated with pneumonia and polyarthritis in cattle. The present investigation included a retrospective case-control study to identify potential herd-level risk factors for M. bovis associated disease, and a prospective cohort study to evaluate the course of clinical disease in M. bovis infected dairy cattle herds in Switzerland. Eighteen herds with confirmed M. bovis cases were visited twice within an average interval of 75 d. One control herd with no history of clinical mycoplasmosis, matched for herd size, was randomly selected within a 10 km range for each case herd. Animal health data, production data, information on milking and feeding-management, housing and presence of potential stress- factors were collected. Composite quarter milk samples were aseptically collected from all lactating cows and 5% of all animals within each herd were sampled by nasal swabs. Organ samples of culled diseased cows were collected when logistically possible. All samples were analyzed by real-time polymerase chain reaction (PCR). In case herds, incidence risk of pneumonia, arthritis and clinical mastitis prior to the first visit and incidence rates of clinical mastitis and clinical pneumonia between the two visits was estimated. Logistic regression was used to identify potential herd-level risk factors for M. bovis infection. In case herds, incidence risk of M. bovis mastitis prior to the first visit ranged from 2 to 15%, whereas 2 to 35% of the cows suffered from clinical pneumonia within the 12 months prior to the first herd visit. The incidence rates of mycoplasmal mastitis and clinical pneumonia between the two herd visits were low in case herds (0-0.1 per animal year at risk and 0.1-0.6 per animal year at risk, respectively). In the retrospective-case-control study high mean milk production, appropriate stimulation until milk-let-down, fore-stripping, animal movements (cattle shows and trade), presence of stress-factors, and use of a specific brand of milking equipment, were identified as potential herd-level risk factors. The prospective cohort study revealed a decreased incidence of clinical disease within three months and prolonged colonization of the nasal cavity by M. bovis in young stock. PMID:25884203

    The purpose of this study was to determine the prevalence of environmental mastitis in dairy herds and identify the main environmental pathogens, and to evaluate the influence of season, housing and management. A total of 20,310 quarters of 5216 animals from 52 dairy herds in 32 counties was examined. Milk samples were aseptically collected for laboratory examination from mammary glands testing positive to any of the field tests. From these, 736 environmental infections were identified. The most frequently isolated environmental pathogens were algae of the genus Prototheca sp. (41.2%), Streptococcus uberis (21.1%), fungi (19.5%), enterobacteriacea (8.3%) and Nocardia sp. (6.6%). The occurrence of mastitis was not influenced by the herd size, use of dry cow therapy, or post milking teat dipping. A tendency for increased occurrence of environmental mastitis during the months of September to February (hot and wet weather) was observed, suggesting a seasonal influence. PMID:9557128

    Mastitis is defined as the inflammatory response resulting of the infection of the udder tissue and it is reported in numerous species, namely in domestic dairy animals. This pathology is the most frequent disease of dairy cattle and can be potentially fatal. Mastitis is an economically important pathology associated with reduced milk production, changes in milk composition and quality, being considered one of the most costly to dairy industry. Therefore, the majority of research in the field has focused on control of bovine mastitis and many efforts are being made for the development of new and effective anti-mastitis drugs. Antibiotic treatment is an established component of mastitis control programs; however, the continuous search for new therapeutic alternatives, effective in the control and treatment of bovine mastitis, is urgent. This review will provide an overview of some conventional and emerging approaches in the management of bovine mastitis' infections. PMID:26687332

  5. Value of magnetic resonance mammographic at 1.5 T in the differential diagnosis of mastitis versus inflammatory carcinoma

    International Nuclear Information System (INIS)

    Purpose: The distinction between mastitis and inflammatory breast carcinoma is an important one. Current methods of evaluation including mammography, ultrasound and clinical examination do not enable this distinction. Dynamic magnetic resonance mammography (MRM) is a study with potential in this regard. Material and methods: 12 patients, in whom clinical examination, mammography and ultrasound could not distinguish between both diseases, were reviewed retrospectively by means of MRM using a 1.5 T Siemens Magnetom SP and a circular mamma coil. We used dynamic 3-D gradient echo sequences with a duration of one minute. Results: At present MRM cannot definitely distinguish between mastitis and inflammatory carcinoma, 80% of the inflammatory carcinomas were found to enhance more than 100% in the first minute, compared to 43% for mastitis. No other differences were seen. Conclusion: MRM proved useful in the follow-up of treated mastitis to demonstrate the success of antibiotic treatment of mastitis and to diagnose a histologically unconfirmed inflammatory carcinoma by means of a different follow-up.

    Investigations of mastitis prevalence were performed in 1227 dam-daughter pairs during 1985-1988. From the records of the last 10 years, the findings concerning mammary gland were obtained. Six herds of agricultural co-operatives in the Brno region were investigated. In the early period the Bohemian Pied breed, later the crosses of this breed with Red Holstein and a low genetic proportion of Ayrshire cattle, dominated in the set of cows. Udder health was assessed using the clinical and bacteriological findings in individual udder quarters and the results of the rapid mastitis test NK. Based on this data, the cows were divided into two groups--resistant and susceptible. The lactation order in which the disease appeared for the first time was of great importance. The occurrence of the disease in daughters and udder health in dams were in a significant relation (P less than or equal to 0.01). While nearly 50% of daughters of susceptible dams were affected, it was only 25% in daughters of the resistant group. The assessment of heritability of resistance to mastitis was carried out on the principle of dam-daughter regression. The index of heritability ĥ2 = 0.52 +/- 0.06 was calculated. The results show that the genetic contribution of dams to the susceptibility of daughters to mastitis is significant. PMID:2219625

  10. Vesical Leiomyoma: Presentation of a clinical case

    International Nuclear Information System (INIS)

    The vesical leiomyoma is a tumor of mesenchymal origin, and extremely rare. Most of them are diagnosed casually after the pathologic study of samples collected after surgery. Few cases were found in the reviewed literature, leading us to think of the scarce incidence of this kind of tumors. We present a case treated in our service, of an 18-years-old female patient, assisting to our consultation presenting a polaquiuria, ardor and mictional effort. The complementary exams led to the surgical treatment and follow up of the patient

    The mucopolysaccharidoses (MPSs) are a heterogeneous group of rare inherited disorders caused by deficiency of lysosomal enzyme necessary to break down mucopolysaccharides or glycosaminoglycans (GAGs). We had combined clinical findings and ophthalmological features. Biochemical test for urine glycosaminoglycans was done for confirmation of diagnosis in the patient. The case of Sanfillippo's disease was characterized by delayed development, hyperactivity with aggressive behaviour. Coarse facial feature, hirsutism and sleep disorder. Urine GAG tests for MPS was positive in the case. Based on clinical findings and biochemical tests for MPS, this case was diagnosed as a type III mucopolysaccharidoses. Urinary GAG's electrophoresis is an important screening test for MPS suspected cases. PMID:25298638

Methods A retrospective analysis was performed on clinical features, laboratory findings, imaging profiles, treatment and outcomes of 22 patients with HE who were admitted to our hospital between June 2010 and September 2013. Results Clinical symptoms were mainly acute or subacute cognitive impairment (9 cases, psychiatric symptoms (6 cases, seizures (5 cases, ataxia (5 cases, stroke-like episodes (6 cases, tremor (1 case, myoclonus (2 cases and disturbance of consciousness (3 cases. Marked increase was found in serum anti-thyroid peroxidase (anti-TPO antibody level (19 cases and anti-thyroglobulin (anti-TG antibody level (20 cases. Twenty-one cases were treated with glucocorticoids, and one patient was treated only with general neurotrophic therapy, such as ganglioside. Except for 4 cases showed bad response to steroids, the rest patients had an obvious improvement. Conclusions Hashimoto's encephalopathy is an encephalopathy with the presence of elevated antithyroid antibodies, and most patients showed good response to steroids. So early diagnosis and treatment is particularly important for improving prognosis. This disease should be considered as an important differential diagnosis for encephalopathy of unknown etiology, and screening for serum antithyroid antibodies should be performed as initial screening test.doi: 10.3969/j.issn.1672-6731.2014.07.008

    Healthcare workers are now being targeted for marketing of diagnostic tools for mastitis that were developed for the dairy industry and which aim to provide information regarding choice of antibiotic treatment. Meanwhile, scientists are striving to understand how the human microbiome affects health and wellbeing and the importance of maintenance of bacterial balance in the human body. Breast milk supplies a multitude of bacteria to populate the baby's intestinal tract and kick-start the immune system. Researchers propose a paradigm shift in the understanding of bacterial content in breast milk and an alternative paradigm for the understanding of lactational mastitis: there is the beginning of evidence that many cases of lactational mastitis will resolve spontaneously. An international group of researchers is attempting to answer how dietary habits, birth mode, genetics and environmental factors may impact the bacterial content of breast milk. Until we have more comprehensive knowledge about the human milk microbiome, diagnostic aids for identification of women in need of antibiotic therapy for mastitis remain unreliable. Diagnostic aids could lead to the injudicious use of antibiotic therapy, which in turn may rob the infant of bacteria valuable for development of its immune system. The marketing of diagnostic aids for use in human medicine, that were originally developed for use in cows, is neither evidence-based nor good ethical practice. PMID:26877759

  6. Teaching clinical reasoning: case-based and coached.

    Kassirer, Jerome P

    2010-07-01

    Optimal medical care is critically dependent on clinicians' skills to make the right diagnosis and to recommend the most appropriate therapy, and acquiring such reasoning skills is a key requirement at every level of medical education. Teaching clinical reasoning is grounded in several fundamental principles of educational theory. Adult learning theory posits that learning is best accomplished by repeated, deliberate exposure to real cases, that case examples should be selected for their reflection of multiple aspects of clinical reasoning, and that the participation of a coach augments the value of an educational experience. The theory proposes that memory of clinical medicine and clinical reasoning strategies is enhanced when errors in information, judgment, and reasoning are immediately pointed out and discussed. Rather than using cases artificially constructed from memory, real cases are greatly preferred because they often reflect the false leads, the polymorphisms of actual clinical material, and the misleading test results encountered in everyday practice. These concepts foster the teaching and learning of the diagnostic process, the complex trade-offs between the benefits and risks of diagnostic tests and treatments, and cognitive errors in clinical reasoning. The teaching of clinical reasoning need not and should not be delayed until students gain a full understanding of anatomy and pathophysiology. Concepts such as hypothesis generation, pattern recognition, context formulation, diagnostic test interpretation, differential diagnosis, and diagnostic verification provide both the language and the methods of clinical problem solving. Expertise is attainable even though the precise mechanisms of achieving it are not known. PMID:20603909

    Actinomycosis is a chronic infection due to an anaerobic Gram positive commensal bacteria harbored in the healthy cavities. From the main localizations in facial, respiratory and gynecology cavities, the infection can progress forming abdominothoracic or pelvis tumors simulating pseudo-neoplastic formations. Macroscopic diagnosis of this uncommon disease is difficult even intraoperatively. The extemporaneous pathology examination confirms the presence of actinomyces grains. We report two cases of abdominopelvic actinomycosis which developed on a "forgotten" intrauterine device leading to torpid severe disease. Actinomyces are sensitive to penicillin if treatment is continued for several months but infiltrations into the urinary and digestive tract may lead to fistulae and hydronephrosis. PMID:8945839

    1998-01-01

    Full Text Available Las cuantiosas pérdidas económicas por mastitis en los rebaños lecheros, especialmente de carácter subclínica, por menor producción y menor calidad higiénica y nutricional de la leche, justifican plenamente el control de la enfermedad. Durante el proceso de la ordeña existe un alto riesgo de infección intramamaria y de transmisión de los agentes causantes de mastitis, especialmente, de los patógenos contagiosos. En consecuencia, para reducir los riesgos de infección es necesario realizar una buena rutina de ordeño extremando las medidas de higiene y evitando al máximo los factores predisponentes por el inadecuado uso de la máquina de ordeño. Una adecuada rutina de ordeño involucra una serie de procedimientos que deben realizarse cuidadosamente en cada período de ordeño en forma correcta y consistente que se pueden resumir en los siguientes aspectos: proporcionar un ambiente limpio y tranquilo a las vacas evitando el estrés; extraer y examinar los primeros chorros de leche para detectar mastitis clínica y estimular la bajada de la leche; lavar y secar completamente los pezones con toallas individuales desechables para reducir la transmisión de los patógenos mamarios y minimizar la contaminación de la leche; colocar las pezoneras dentro de 1 minuto de iniciada la estimulación para lograr una ordeña completa; observar y ajustar cuando sea necesario las unidades de ordeño para evitar la entrada de aire al sistema; cortar el vacío antes de retirar las pezoneras; y desinfectar los pezones al término de la ordeña con una solución desinfectante segura y eficaz. Opcionalmente, en determinados rebaños se puede agregar a esta rutina la desinfección de los pezones antes de la ordeña (pre"dipping" y la desinfección de las pezoneras al pasar de una vaca a otra durante la ordeñaEconomic losses due to mastitis in dairy herds, in particularsubclinical mastitis, because of less milk yield and poor milk quality,make its control a goal to be achieved in every dairy herd. The risk of intramammary infection and transmission of mastitis pathogens,mainly contagious organisms, is higher during milking. Consequently, agood milking routine and udder preparation greatly reduces the risk ofinfection, being specially important the hygiene and the milking machineinducing factors. A good milking routine involves a number of procedures which must be properly and carefully practised at every single milking. These procedures can be summarised as follows: provide cows with a clean environment, free of stress; check foremilk using a strip-cup to detect clinical mastitis and stimulate milk let-down; wash and thoroughly dry the surface of the teats with an individual disposable paper towel to reduce the spread of mastitis pathogens and to avoid milk contamination during milking; attach the teat cups within 1 minute after initiating udder preparation to get the maximum effect of oxytocin; check and adjust the milking units, as needed, to avoid air admission and prevent liner slip; shut off the vacuum before detaching the milking units to prevent impact; disinfect teats after milking with a safe and effective teat dip to destroy mastitis pathogens remaining on the teat. In some herds, other optional measures can be added to this routine, mainly teat disinfection before milking (predipping and disinfection of clusters between cows during milking

    Idiopathic granulomatous mastitis (IGM) is an uncommon chronic inflammatory lesion of the breast with an uncertain optimal treatment regimen, the physical examination, and radiologic features of which may be confused with breast carcinoma. In this study, we aimed to describe the clinicopathologic characteristics of 33 patients who admitted to our breast policlinic and took the diagnosis of granulomatous (idiopathic and non-idiopathic) mastitis, and report the place of corticosteroids and the timing of surgery in the treatment of patients with IGM. The clinical features of 33 patients who presented to our breast policlinic with the complaint of breast mass and reached the final diagnosis of GM between March 2005 and October 2009 were reported. The most common symptoms were mass (n: 27) and pain (n: 11). Ultrasonography (USG) and biopsy were performed in all of the patients. Mammography (MMG) was performed in 9, and magnetic resonance imaging (MRI) in 10 patients. The diagnosis of idiopathic lobular granulomatous mastitis (ILGM) was made in 25 patients and tuberculous mastitis (non-idiopathic GM) in the remaining 8 patients. Twenty-four patients received steroid treatment except one who was pregnant. After giving birth, she also received steroids. One of the patients who developed recurrence after 11 months repeated the steroid therapy. Eight patients with tuberculous mastitis were placed on a regimen of antituberculosis therapy for 6 months. In the diagnosis of IGM, physical examination, USG, MMG, and even MRI alone may sometimes not be enough. They should be discussed altogether and the treatment should begin after definitive histopathologic result. Fine needle aspiration biopsy for cytology will result in a high level of diagnostic accuracy, however, core biopsy will reinforce the exact result. Corticosteroid therapy has been shown to be efficacious for IGM, but in the existence of complications such as abscess formation, fistulae, and persistent wound infection, surgical treatment has been the first method of choice.

    The port of Rotterdam, The Netherlands, is the world's largest container port. In 2006, one of these containers caused a chemical incident. Methylbromide is used in some countries as a pesticide for the fumigation of maritime containers. Because of an insufficiently performed detoxification, this insecticide intoxicated several employees and some of the ambulance crew and Mobile Medical Team (MMT). The victims displayed symptoms of sore throat, irritated eyes, and hypersalivation. One of the victims suffered from multiple epileptic seizures. Two victims were admitted to the intensive care unit for respiratory support. Three other employees showed milder symptoms and received supportive care but were not admitted to the hospital. This complicated case shows that the safety of the ambulance crew and MMT must be guaranteed. It also demonstrates that healthcare providers cannot always oversee the accident scene and that there are some pitfalls that are almost impossible to prevent. PMID:20118865

    Full Text Available Sub-clinical mastitis is a main pathology of dairy husbandry because it is not clinically recognized by the owners and the veterinarians. For this reason, its economic loss is usually underestimated in milk production. This study has been undertaken in order to evaluate the epidemiologic situation of sub-clinicalmastitis in Batna and Setif governorates (East of Algeria. For this purpose, a detailed bacteriological study of all bacterial strains isolated from sub-clinical mastitis followed by a study of their antibacterial susceptibility profiles has been undertaken. 89 bacterial strains distributed as follows were studied: 27 strains of staphylococci among which 23 were coagulase-negative staphylococci (CNS that are generally incriminated in sub-clinical mastitis. 39 strains of streptococci among which 10 were Lactococcus lactis ssp lactis strains. 23 strains of enterobacteria represented mainly by Escherichia coli (E.coli. All these bacterial strains were isolated from cow milk of 3 different farms. The antibacterial susceptibility profiles have revealed a susceptibility of the isolated strains to a large number of antibiotics mainly to the Neomycin, the Cephalexin and the Spiramycin. [Vet.

The present study aimed to isolate and identify of bacteria causes mastitis in dairy cows and to evaluate the antibacterial activities of some selected medicinal plants extracts comparing antibiotics used in the treatment of mastitis in Egypt. Materials and Methods: A total of 203 milk samples of dairy cows were collected during the period from February to June 2013 at different Governorates in Egypt. The use clinical inspection and California mastitis test examination were provided efficient diagnostic tool for detection of clinical, subclinical mastitis and apparently normal health cattle. The collected milk samples were cultured on Nutrient, Blood agar, Mannitol salt, Edward’s and MacConkey agar plates supporting the growth of various types of bacteria for their biochemical studies and isolation. The antimicrobial activity of plants extracts (Jasonia montana and Artemisia herb albawith different solvent (ethanol, petroleum ether, chloroform and acetonewere studied in vitro against isolated bacteria from mastitis by paper desk diffusion and minimum inhibitory concentration method (MIC. Results: The prevalence of clinical, subclinical mastitis and normal healthy animals were 34.50%, 24.7% and 40.8% respectively. The major pathogens isolated from collected milk samples were Escherichia coli (22.16%, Staphylococcus aureus (20.19%, Streptococcus spp. (13.3%, Streptococcus agalactiae (12.8%, Streptococcus dysgalactia (0.5%, Pasteurella spp. (2.45%, Klebsiella spp. (1.47%and Pseudomonas spp. (0.45%. The highest antibacterial activity of J. montana plant extracted with acetone solvent against S. agalactiae, E. coli, S. aureus, Klebsiella spp and coagulase-negative Staphylococci with zone of inhibition values ± standard deviation (SD, ranging from 4.33±0.57 to 25.6±0.60 mm. The MIC values for the extracts ranged from 0.01 to 1.56 mg/ml. when comparing antibacterial activity of A. herb alba plant extracted with acetone solvent on the same bacteria with zone of inhibition values ± SD, ranging from 00±00 to 5.6±0.60 mm. Both extracts from J. montana and A. herb alba plant extracts with petroleum ether, methanol and chloroform solvent were less antibacterial activities than acetone solvent extract. Conclusion: The present study spot highlight on isolation and identification of mastitis pathogens that are fundamental aspects of milk quality, udder health control programs and public health and food safety issues associated with food borne pathogens. J. montana and A. herb alba plants have antibacterial effects more than antibiotics used in the treatment of mastitis. Finally, the medicinal plant extracts can be used to discover bioactive natural product in the form of antibacterial that may be serve the development of new pharmaceutical products. But still need further research necessary to identify active compounds and research to mechanism and drug interaction.

    Full Text Available Mastitis is an inflammatory condition of the mammary gland caused by microorganisms as diverse as bacteria, viruses, mycoplasma, yeasts and algae. Mastitis is an economically devastating disease mainly affecting the crossbred cattle in India. Control strategies against mastitis includes antibiotic therapy, vaccination, improvements in dairy cattle husbandry, farm and feeding management etc. but has met with little success.. Mastitis tolerance/susceptibility is difficult to measure directly and hence milk somatic cell count (SCC or milk somatic cell score (SCS is used as an indicator trait for mastitis as both traits are highly positively correlated. Single nucleotide polymorphism (SNP marker is a single base change in a DNA sequence at a given position. SNP markers are the most preferred genetic markers nowadays. Currently most researches worldwide have been targeting molecular high density SNP markers that are linked to mastitis tolerance in an attempt to incorporate to understand the genetics of host resistance to mastitis and this knowledge will be helpful in formulating breeding programmes in an attempt to control mastitis. This article reviews various SNPs which are reported to be significantly associated with mastitis tolerance/susceptibility.

    The objective of this study was to investigate the potential use of bacteriophage in preventing Escherichia coli mastitis on dairies. A cocktail consisting of 4 distinct bacteriophages was generated by screening against 36 E. coli isolates from dairy cows in Washington State with clinical mastitis. The bacteriophage significantly inhibited growth of 58% of the Washington State isolates and 54% of E. coli mastitis isolates from New York State, suggesting that the cocktail of phages had a relatively broad spectrum of action against relevant strains from 2 distinct geographies. The ability to suppress bacterial growth of these isolates in a liquid growth medium was not affected by the ratio of bacteriophage particles to bacterial cells (multiplicity of infection, MOI). For those E. coli that were completely inhibited by the phage cocktail, an MOI as low as 10had the same effect as 10µg/mL of ceftiofur on the growth rate of E. coli over a 12-h period using optical density measurements. A 3.3- to 5.6-log reduction of growth was achieved when E. coli was co-incubated with our phage cocktail in raw milk over a 12-h period at physiologic temperature. A modified gentamicin protection assay using bovine mammary epithelial cells provided a model to test whether bacteriophage could prevent cell attachment and invasion by chronic coliform mastitis strains. Pretreatment of cell cultures with the phage cocktail significantly reduced adhesion and intracellular survival of E. coli compared with controls. When combined with a bismuth-based teat sealant, the phage cocktail was able to inhibit bacterial growth when challenged with 1.6×10(3) cfu/mL of a clinical mastitis E. coli strain. In vitro results show bactericidal activity by our phage in raw milk and mammary tissue culture systems. Before a bacteriophage-based dry-cow treatment becomes a potential option for dairies, in vivo studies must be able to demonstrate that a specific dose of bacteriophage can protect cows from experimentally induced E. coli mastitis without inducing an inflammatory reaction.

    Mastitis is an inflammatory condition of the breast with common symptoms of pain, swelling, erythema, warmth, and fever. Diagnosis of mastitis is easily made on the basis of typical symptoms and ultrasonographic findings, such as diffusely increased echogenicity of the parenchyma and subcutaneous fat, or skin thickening. However, when it occurs in women middle-aged or older, associated malignancy should be considered. In our cases, we detected irregular hypoechoic malignant masses after the disappearance of inflammatory changes. Therefore, when non-puerperal women have inflammatory signs on their breast, follow-up imaging should be performed. In particular, in the case of persistent or growing palpability after the recovery of breast inflammation, percutaneous core biopsy and short-term follow-up with ultrasonography should be considered to exclude the associated malignancy.

Para determinar a frequência de mastite subclínica, um estudo prospectivo foi realizado com animais de produção (n=47 durante o período de lactação, utilizando o CMT (Califórnia Mastite Teste e foi determinada uma frequência de 38,69% de casos positivos (reacções positivas: uma, duas e três cruzes em média. Para a mastite clínica foi feito um estudo retrospectivo em toda a população (n=91, a partir de casos clínicos e foi encontrada uma incidência anual de 9.2%. Além disso, foram estabelecidas potenciais associações, utilizando um modelo estatístico para determinar o efeito da substituição genética do alelo DRB3.2*24. Os alelos associados à susceptibilidade à mastite foram DRB3.2 * 8 (pThe Mayor Histocompatibility Complex (MHC is a pool of genes which regulate both processing and recognition of antigens. The MHC is the main genetic component of the resistance or susceptibility to infectious diseases. In bovines, MHC is known as Bovine Leukocyte Antigen (BoLA, and some of its alleles have been associated with udder health issues. This study evaluated exon-2 polymorphisms of BoLA DRB3 gene in 91 cows of a dairy farm. A total of 66 Holstein and 25 cross breed BON x Holstein (BxH cows were evaluated. Twenty seven alleles were identified by PCR-RFLP and PCR-SBT. Allelic frequencies varied from 0.8 to 15.9% for the Holstein, and from 2 to 20% for BxH cows. The BoLA DRB3.2*23 was the most frequent allele in both groups. A prospective study was also conducted for cows in production (n=47 during one lactation to determine subclinical mastitis incidence using the California Mastitis Test (CMT. A 38.69% frequency of positive cases was observed. Additionally, a retrospective study was conducted for all the cows (n=91, finding 9.2% incidence of clinical mastitis per year. Possible associations were established using a statistical model to determine the effect of genetic substitution, in which BoLA DRB3.2*24 was used as the substitution allele. Alleles associated with susceptibility to subclinical mastitis were DRB3.2*8 (p<0.10 and DRB3.2*14 (p< 0.01. Allele DRB3.2*33 was associated with resistance to subclinical mastitis (p<0.01. No significant associations were found for clinical mastitis.

    Full Text Available The study was conducted in 2006 on 20 French alpine goat farms in Croatia. Milk samples were taken from each udder half, for the mastitis test and the bacteriological test, 2120 samples in total. Subclinical mastitis was diagnosed in 211 out of 1060 goats, or in 20% of the studied population. Mastitis of one udder half was diagnosed in 84% of the affected population, while mastitis of both udder halves was diagnosed in 16% of the affected goats. A positive mastitis test reaction was identified in 605 samples (28%, and the pathogenic bacterium was isolated from 244 of these samples (36%. From 22 samples (1.5% which were negative to mastitis test, pathogenic bacteria, namely S. aureus (21 samples and Streptococcus D (1 sample, were isolated. Staphylococcus aureus was isolated from 72% mastitis test positive samples, coagulase-negative staphylococci in 16%, other bacteria were isolated from a smaller number of samples: Streptococcus D (6%, Bacillus spp. (2%, and E. coli (2%. The results of the study lead to the conclusion that the subclinical mastitis in goats has a prevalence of 20% on average which increases with higher lactation number. Staphylococcus aureus is the primary causative agent of the inflammations.

    Full Text Available Purpose: If measurements of the increased total count of somatic cells in the individual udder quarter or in the whole udder could be determined with electric conductivity by means of the microprocessor-controlled device Mastitron LF 3000 enough precisely to predict the presence of subclinical mastitis.Design/methodology/approach: The occurrence of increased count of somatic cells in milk was found out group by group by the method of measuring the electric conductivity of milk. For the milk conductivity the average measurement from all four udder quarters was taken into account. The population of 102 lactating cows (Black and white, Simmental and Brown Swiss breed on seven farms fore three summer months was observed.Findings: It was established that higher average electric conductivity than 6.5 mS/cm confirmed in 80% also the increased count of somatic cells in milk. When evaluating the differences between the quarters exceeding 1 mS/cm also a higher total count of somatic cells was confirmed in 73.7%. Moreover, statistically significant relation (P<0.01 between the CMT test and the ECM was found out so it can be claimed that the two methods do not exclude themselves mutually.Research limitations/implications: It was found that the reliability of the ECM in our case was 80% depending to a large extent on the milk composition which changed depending on the stage of lactation, type of feed and general health condition of animals. For a more reliable, accurate and faster implementation of the ECM method further researches will be necessary.Practical implications: Though the ECM method of determination of the subclinical mastitis of the milch-cows is well established in the world, it is not yet known well enough in the Slovene practice as a method of diagnosing the subclinical mastitis.Originality/value: It was found that the results of our research in production circumstances were comparable with the indications of the maker and foreign researchers.

  8. Friedreich's ataxia: clinical and molecular study of 25 Brazilian cases

    Albano Lilian M. J.

    2001-01-01

    Full Text Available INTRODUCTION: Friedreich's ataxia is a neurodegenerative disorder whose clinical diagnostic criteria for typical cases basically include: a early age of onset (< 20 or 25 years, b autosomal recessive inheritance, c progressive ataxia of limbs and gait, and d absence of lower limb tendon reflexes. METHODS: We studied the frequency and the size of expanded GAA and their influence on neurologic findings, age at onset, and disease progression in 25 Brazilian patients with clinical diagnosis of Friedreich's ataxia - 19 typical and 6 atypical - using a long-range PCR test. RESULTS: Abnormalities in cerebellar signs, in electrocardiography, and pes cavus occurred more frequently in typical cases; however, plantar response and speech were more frequently normal in this group when the both typical and atypical cases were compared. Homozygous GAA expansion repeats were detected in 17 cases (68% - all typical cases. In 8 patients (32% (6 atypical and 2 typical, no expansion was observed, ruling out the diagnosis of Friedreich's ataxia. In cases with GAA expansions, foot deformity, cardiac abnormalities, and some neurologic findings occurred more frequently; however, abnormalities in cranial nerves and in tomographic findings were detected less frequently than in patients without GAA expansions. DISCUSSION: Molecular analysis was imperative for the diagnosis of Friedreich's ataxia, not only for typical cases but also for atypical ones. There was no genotype-phenotype correlation. Diagnosis based only on clinical findings is limited; however, it aids in better screening for suspected cases that should be tested. Evaluation for vitamin E deficiency is recommended, especially in cases without GAA expansion.

    International Nuclear Information System (INIS)

    Objective: To analyze the characteristics of clinical symptoms, examinations, and treatments in patients with intracranial germinoma. Methods: Medical records of 33 cases with intracranial germinoma between January 2000 and January 2011 were retrospectively reviewed. Results: The study population consisted of 26 males and 7 females. Eighteen patients had a single tumor and 15 patients had multiple tumor. Twelve (36.4% ) were in the sellar region, 13 (39.4% ) in the pineal region, 5 cases (15.2% ) in basal ganglia and 9 cases in the periventricular region. Clinical manifestations: 21 patients (63.7% ) had headache, nausea and vomiting; 10 (30.3% ) had blurred vision and visual field damage; 11 (33.3% ) patients had diabetes insipidus and 7 patients (21.2% ) had limb weakness. Image study: MRI examination showed long T1, T2 or abnormal T1, T2 in MRI, which were enhanced equally by contrast medium. Diagnostic methods: 17 cases were confirmed by pathological diagnosis and 16 cases by diagnostic radiotherapy. Treatment: 3 cases underwent resection; 4 cases with obstructive hydrocephalus underwent ventriculoperitoneal shunt, and 10 patients underwent stereotactic surgery. All the patients underwent radiotherapy combined with chemotherapy. Symptoms were relieved obviously, but 2 patients had spinal cord metastasis. Conclusion: The increased intracranial pressure, polyuria, diplopia are the most common clinical symptoms of intracranial germ cell tumors. Common locations of lesions are the saddle area and pineal region. The whole brain + local radiotherapy combined with chemotherapy treatment is a common and effective modality for intracranial germinoma. Most patients have clinical symptoms remission and long survival. (authors)

    Full Text Available Background and design: DRESS (Drug Rash with Eoshinophilia and Systemic Symptoms syndrome is a severe reaction induced by drugs and accompanied by cutaneous, hematologic and solid organ involvement. Since the syndrome requires specific treatments and has high mortality rates, early diagnosis is very important. In our country, any descriptive study has not been reported about patients with DRESS syndrome except for a few case presentations. Therefore, we aimed to investigate the clinical characteristics of patients with DRESS syndrome diagnosed and treated in our inpatient clinic. Material and method: The records of patients diagnosed as DRESS syndrome or drug eruption were retrospectively analyzed. Scoring system created by a RegiSCAR group was used. Patients with certain, probable and possible DRESS syndrome were identified. Clinical features, laboratory findings and etiological factors were noted. Results: Seven males and 4 females with DRESS syndrome were enrolled. Nine patients were identified as definite case and two were probable DRESS syndrome. Aromatic anticonvulsants were the only responsible drugs (phenytoin in 5, carbamezepine in 3, lamotrigine in 3 patients. All patients had cutaneous manifestations and hematological abnormalities. Fever, liver function impairment, lymphadenopathy, renal disease and pneumonia were the clinical findings in order of frequency. Cessation of responsible drugs and treatment with systemic corticosteroids achieved full remission in all patients. Conclusion: DRESS syndrome may present with various clinical manifestations. Because signs and symptoms form the basis for recognition of the disease, good knowledge of clinical features is important in early diagnosing of DRESS syndrome and reduction of mortality and morbidity.

    The aim of this study was to evaluate the prevalence of mycotic mastitis in different mammary gland statuses. The study was conducted on 304 dairy cows from ten farms in two north-eastern regions in Algeria; Guelma and Souk Ahras with 922 and 199 samples, respectively, forming thus a total number of 1,121 milk samples. A total of 321 milk samples were collected from clinical mastitis, 544 milk samples from subclinical mastitis and 256 milk samples from healthy mammary glands. Mycological analyses revealed that 10.17% of the treated samples were positive recording 114 species of fungi including 88 yeasts and 26 moulds. The most frequent species was Candida kefyr followed by C. albicans, C. guilliermondii, C. famata, C. tropicalis, C. colliculosa, C. krusei, C. rugosa, C. glabrata, C. parapsilosis, C. inconspicua, Trichosporon sp., Rhodotorula glutinis and Saccharomyces fragilis. Mould species have also been isolated from samples of both healthy milk and clinical mastitis milk. Aspergillus amstelodami (from glaucus group), A. fumigatus and Geotrichum candidum were identified, while the other species including Penicillium sp. and Cladosporium sp. were not identified.

    Streptococcus uberis is the most common environmental mastitis pathogen causing udder inflammations of different severities in dairy cows. The aim of the study was to investigate if the different clinical outcome of mastitis induced by different strains of S. uberis can be reflected in the mammary immune response. Mammary epithelial cells and somatic milk cells were treated with heat inactivated and living S. uberis of strain A and strain B in vitro. Strain A was repeatedly isolated from a chronically infected quarter during 8 months, and persisted in the quarter despite antibiotic treatment. Strain B caused an acute clinical mastitis and was not further isolated after a single antibiotic treatment. Treatment with Strain B induced a more pronounced increase of mRNA-expression of various immune factors (interleukin-8, interleukin-1beta, RANTES, and lactoferrin) in mammary epithelial cells than strain A. In contrast to mammary epithelial cells the response of removed somatic milk cells showed no differences between the stimulation with two S. uberis strains. Tumor necrosis factor-alpha mRNA expression was not differently induced by the two strains. In conclusion, the characteristics of different severities of mastitis that are induced by different S. uberis strains in vivo can also be reflected at the level of the immune response of the mammary gland in vitro.

    Full Text Available Background: Crescentic glomerulonephritis (CrGN, defined as crescents involving more than 50% of the glomeruli, includes pauci-immune, immune complex-mediated and anti-glomerular basement membrane disease. Objectives: The present study was aimed at evaluating the various clinical, biochemical and histological parameters in CrGN with respect to these categories and clinical outcome. Materials and Methods: Renal biopsies diagnosed as CrGN between Jan 2008 and Feb 2010 were included. Clinical and laboratory parameters were retrieved along with the therapeutic approach and clinical outcome, wherever available. Renal biopsy slides were evaluated for various glomerular, tubulo-interstitial and arteriolar features. Appropriate statistical tests were applied for significance. Results: A total of 46 cases of CrGN were included; majority (71.7% of cases were pauci-immune (PI while 28.3% were immune complex-mediated (IC. Among clinical features, gender ratio was significantly different between PI and IC groups (P = 0.006. The various histological parameters, including proportion of cellular crescents, tuft necrosis and Bowman?s capsule rupture, were similar in both the groups. Four unusual associations, including idiopathic membranoproliferative glomerulonephritis (MPGN, multibacillary leprosy, acute lymphoblastic leukemia and C1q nephropathy were detected. Adequate follow-up information was available in 21 (46% of the patients. Of these, 11 (52.4% were dialysis-dependent at the last follow-up. Adult patients required renal replacement therapy more frequently than pediatric cases (P = 0.05. Presence of arteriolar fibrinoid necrosis also showed association with poor clinical outcome (P = 0.05. Conclusions: Crescentic glomerulonephritis remains one of the main causes of acute renal failure with histological diagnosis. Immunohistologic examination is essential for accurate classification into one of the three categories. This condition should be considered in rare causal associations like leprosy or MPGN with renal failure, to allow for timely performed renal biopsy and appropriate aggressive therapy.

Results. The patient had a history of an allergic reaction as urticaria to the ingestion of fish products. His examination showed practically all diagnostic criteria for allergic myocarditis: hypereosinophilia (the admission level of eosinophils was 9% with their further normalization; the characteristic clinical presentation of myocarditis (pressing retrosternal pain; elevated levels of cardiac specific enzymes (creatinine phosphokinase-MB, lactate dehydrogenase, troponin T; ECG changes myocardial hypokinesis in the acute period, followed by its pattern normalization. of the pattern. Myocardial scintigraphy (by taking into account the fact that the patient had had a new allergic reaction episode, the investigators decided not to perform coronary angiography revealed decreased radiopharmaceutical accumulation in the lower left ventricular wall in the right coronary arterial bed; perfusion remained in the other myocardial walls. Conclusion. This clinical case reflects the specific features of the course of and difficulties in the diagnosis of acute allergic myocarditis that, in most cases, has no specific clinical manifestations and may mimic different diseases.

  2. Managed care contracts. A guide for clinical case managers.

    1996-01-01

    When healthcare executives speak of managed care, they often use the term generically to refer to any arrangement with a healthcare payer other than traditional fee-for-service reimbursement. All too often, the "management" aspect is missing from managed care, resulting in an arrangement that could more aptly be described as "discounted care." This lack of clinical representation is unfortunate, since there are numerous issues that have an impact on clinical care, including choice of referral providers, noncoverage of certain procedures or treatments, and similar issues that may influence the patient's plan of care. Organizations that approach managed care as a system that blends the resources of management, finance, and clinicians, will enjoy the greatest potential for success. With their practical experience and insight into the administrative and clinical issues that may be encountered, nurse case managers will ultimately be responsible for managing the care of the contracted population. As case managers are the vital link among payers, providers, patients, and families, it is essential that the case manager understand managed care concepts, be conversant in the terminology of managed care, function as a member of the team responsible for evaluating contracts, and periodically review existing arrangements. This article presents an overview of the managed care contract development process, and provides tools to enable the nurse case manager to participate in the contracting process. PMID:9157934

    A 42 year old woman with foot process disease, was treated with corticosteroids for 6 years. She had been suffering, for about 3 years from progressive muscle weakness of the limbs, accompanied by general paresthesia, cramps of the calves and burning muscle pain both at rest and an effort. The clinical, neurophysiological and histochemical examination indicated noninflammatory myopathic damage. The progressive reduction of corticosteroid dosage led rapidly to a distinct improvement, but not to a remission, of symptoms. Clinical and laboratory findings were consistent with those observed in most cases of steroid myopathy described in literature. We discuss the possible pathogenetic role of corticosteroids in this affection. PMID:1791135

Preliminary studies of organic dairy herds have indicated better udder health in such herds, as compared to conventional herds. The aim of this paper was to further study mastitis and management related factors in certified organic dairy herds. Methods An observational study of 26 certified organic dairy herds in mid-eastern Sweden was conducted during one year. A large-animal practitioner visited the herds three times and clinically examined and sampled cows, and collected information about general health and management routines. Data on milk production and disorders treated by a veterinarian in the 26 herds, as well as in 1102 conventional herds, were retrieved from official records. Multivariable logistic regression was used to assess associations between herd type (organic vs. conventional and incidence of disorders. Results The organic herds that took part in the study ranged in size from 12 to 64 cows, in milk production from 3772 to 10334 kg per cow and year, and in bulk milk somatic cell counts from 83000 to 280000 cells/ml. The organic herds were found to have a lower incidence of clinical mastitis, teat injuries, and a lower proportion of cows with a high somatic cell count (as indicated by the UDS, Udder Disease Score compared to conventional herds. The spectrum of udder pathogenic bacteria was similar to that found in other Swedish studies. Treatment of mastitis was found to be similar to what is practised in conventional herds. Homeopathic remedies were not widely used in the treatment of clinical mastitis. The calves in most of these organic herds suckled their dams for only a few days, which were not considered to substantially affect the udder health. The main management factor that was different from conventional herds was the feeding strategy, where organic herds used a larger share of forage. Conclusion Udder health in Swedish organic herds appears to be better than in conventional herds of comparable size and production. The major difference in management between the two types of farms is the proportion of concentrates fed. The mechanisms explaining the association between intensity of feeding and udder health in dairy cows require further research.

    Full Text Available From 1981 to 1992, 109 cases (90 females and 19 males of pemphigus were seen in the Department of Dermatology, Central Hospital Tripoli, Libya. Age of onset of the disease varied from 17 to 85 years, while duration of the disease at the time of presentation varied from 3 days to 13 days. On the basis of clinical features and routine histological findings the cases were divided into various subtypes as : pemphigus foliaceus 65 cases, pemphigus vulgaris 34 patients, pemphigus erythematosus 5, herpetiform pemphigus 3 and vegetans type 2 cases. Three of our patients had diabetes mellitus preceding pemphigus, while 12 patients developed steroid induced diabetes. Significant secondary bacterial infection occurred in all cases at some stage of the disease while oral candidiasis occurred in 15 cases. Eczema herpeticum was seen in 4 patients, while 2 had extensive tinea corporis. One of 4 patients of pemphigus vulgaris had complete shedding of nail and 1 female patient had alternate phases of pemphigus foliaceus and generalized pustular psoriasis. The features in our cases of pemphigus foliaceus were somewhat similar to Brazilian pemphigus foliaceus and we had more cases of pemphigus foliaceus, almost exclusively affecting females.

    Full Text Available The objective of this study was to evaluate herd management practices and mastitis treatment procedures as risk factors associated with Staphylococcus aureus antimicrobial resistance. For this study, 13 herds were selected to participate in the study to evaluate the association between their management practices and mastitis treatment procedures and in vitro antimicrobial susceptibility. A total of 1069 composite milk samples were collected aseptically from the selected cows in four different periods over two years. The samples were used for microbiological culturing of S. aureus isolates and evaluation of their antimicrobial susceptibility. A total of 756 samples (70.7% were culture-positive, and S. aureus comprised 27.77% (n=210 of the isolates. The S. aureus isolates were tested using the disk-diffusion susceptibility assay with the following antimicrobials: ampicillin 10mg; clindamycin 2μg; penicillin 1mg; ceftiofur 30μg; gentamicin 10mg; sulfa-trimethoprim 25μg; enrofloxacin 5μg; sulfonamide 300μg; tetracycline 30μg; oxacillin 1mg; cephalothin 30μg and erythromycin 5μg. The variables that were significantly associated with S. aureus resistance were as follows: the treatment of clinical mastitis for ampicillin (OR=2.18, dry cow treatment for enrofloxacin (OR=2.11 and not sending milk samples for microbiological culture and susceptibility tests, for ampicillin (OR=2.57 and penicillin (OR=4.69. In conclusion, the identification of risk factors for S. aureus resistance against various mastitis antimicrobials is an important information that may help in practical recommendations for prudent use of antimicrobial in milk production.

  11. Clinical study of 20 cases of primary pontine hemorrhage

    International Nuclear Information System (INIS)

    Twenty cases of primary pontine hemorrhage were classified into four types according to their outcome. Five cases in Type I showed a full recovery or could resume most activities (ADL I or II). The initial clinical picture of this type was characterized by alertness, no disturbance of autonomic function, and mild hemiparesis. CT scan demonstrated a small hematoma which was localized in the unilateral region or midportion of the pontine tegmentum. In four cases, the largest diameter of the hematoma on a transverse section through the pons was less than 20 mm, and its extension was limited to 2 slices, (each 10 mm in width). Three cases of Type II recovered to daily life partially assisted (ADL III). Hematoma was located in the bilateral pontine tegmentum and partially involved the pontine basis. The size of hematoma was less than 30 mm and its extension was 2 to 3 slices. Seven cases of Type III were severely disabled in prolonged coma or the ''locked-in'' syndrome (ADL IV). Hematoma was located in the entire pontine tegmentum and unilateral pontine basis extending to the midbrain. The size of hematoma was less than 30 mm in five patients and more than 31 mm in two. Alpha-pattern coma was present in two cases and beta-coma was observed in two. All five cases of Type IV died within a few days after the onset. The clinical picture was coma, tetraplegia, respiratory failure, hyperthemia, and hypertension in all cases. Hematoma involved the entire tegmentum and basis pontis and extended to the cerebellum and midbrain. The size of hematoma was less than 30 mm in two patients and more than 31 mm in three. The sagittal extension was 3 to 6 slices. (J.P.N.)

    International Nuclear Information System (INIS)

    Objective: Imaging and clinical manifestations of melioidosis were analyzed in order to improve our understanding of the disease and to reduce the rate of misdiagnosis. Methods: From 2001 to 2006, 12 melioidosis cases were confirmed by blood, pus and sputum culture. All cases were examined with radiography, and nine of them with CT and 2 with US. The imaging and clinical data were assessed retrospectively. Results: Ten of 12 cases revealed lung abnormalities, the main organ involved by melioidosis in the body. The appearances were observed as follows: diffused sheets and sheets fused partly in bilateral fields of the lungs can be seen on chest radiograph; homogeneous dense shadow of the lobe or segment were observed on plain chest film and CT; blurred strips radiated from hilum were revealed on plain chest film; multitude nodules in 2 lungs showed on CT; cavity with air and liquid be seen on plain chest film and CT; patches and granules in superior and middle fields or (and) inferior fields be seen on plain chest film and CT; arc shadow of water attenuation in dorsal thorax showed on CT. Infections outside the lung can be observed in orbital, lumbar muscle, liver and spleen in 1 case, and thighbone osteomyelitis with multi abscesses in one case. Conclusion: Alhough medioidosis has no characteristic imaging appearances, the disease's location, extent, severity and quantity objectively can be demonstrated by imaging, final confirmation is necessary using the culture of blood, pus and sputum.

    Full Text Available Issues related to mental health in relation to court matters have increasingly required the participation of the psychologist. We present the use of forensic neuropsychological assessment in a case of retirement reversal. Incapacity was attested due to disability resulting from depression of a 35-year-old attorney, and the case was forwarded from the courts to the Forensic Psychiatry and Psychology Unit at the USP Clinical Hospital. A clinical interview and application of cognitive tests was conducted. Despite the depression, significant cognitive losses that would prevent return to his professional assignments were not detected. The neuropsychological assessment has been shown to be an important tool in the forensic context, as it assists with diagnostic value for clarification of functional aspects in the various psychopathological areas in terms of disabilities or potentialities.

    A 33-year-old mother of 2 healthy children presented with bilateral recurrent breast infections despite successful treatment of each episode of an infection. With a negative rheumatologic medical history as well as a negative review of systems, she continued to have these infections frequently. Hence, a breast biopsy was performed after the treatment with a course of antimicrobials, which revealed changes suggestive of granulomatous mastitis. She was started on methotrexate (MTX) with a good response. But, due to persistent nodularity, corticosteroids were added to the regimen with MTX dose escalation. Patient remained disease free thereafter without any adverse effects. PMID:25715328

    Full Text Available Mastitis is an infection of the mammary gland mainly caused by bacteria. In sheep, besides it causes chemical and physical changes in milk with the loss in quality, mastitis changes the glandular tissue which may lead to premature cull-out from the herd. This study aimed to evaluate the diagnostic features of the California Mastitis Test (CMT and somatic cell count (SCC to the identification of subclinical mastitis in sheep according to the micro-organisms isolated. The work is at an early stage and CMT was performed in all ewes. It was considered positive results all degrees of reaction, while the negative reaction was considered when there was not viscosity. Subsequently, samples were collected aseptically from milk and were sent for microbiological analysis. A total of 160 milk samples were analyzed from 85 Santa Inês sheep belonging to the Embrapa Southeast Livestock in São Carlos, São Paulo. Samples were plated on sheep blood agar to 5% and incubated for 24h/72h at 35 ° C. In samples with growth, tests to the identification of the microorganisms were performed, macroscopic characteristics of the colonies and the production or absence of hemolysis, Gram staining, catalase test, coagulase test with rabbit plasma and verification of acetoin production. The sensitivity of the diagnostic tests were determined in accordance to the ratio of the positive tests and the presence of the disease, while the specificities were calculated according to the ratio of the negative results and the absence of disease. The efficiency was based on the percentage of true results that the test was able to provide diagnosis. SCC in milk was determined using the somatic cell count Somacount 300 (Bentley and the presence of the disease was given when isolated coagulase-positive staphylococci (CPS, coagulase-negative staphylococci (CNS, coliforms and other microorganisms (Corinebacteria, strep and association of two bacteria in a same sample. It was used the limit value of 300 000 cells/ml of milk to the screening of the positive and negative samples. A total of 125 samples were negative in the microbiological examination, of which 102 were presented as CMT-negative and 23 were positive to the CMT. Among the positive samples for microbiological analyzes, 12 were negative to the CMT. Thirty-four samples were positive for mastitis after the SCC, from a total of 118. SCC showed greater sensitivity than the CMT for identifying cases of ovine mastitis to the most classes of micro-organisms (67.0% vs. 50.0% for CPS; 80.0% vs. 71.4 % for CNS; and 87.5% vs. 55.6% for other micro-organisms, except for coliforms (85.7% vs. 90.0%, probably by the least amount of results for SCC when compared to CMT. The CMT was more efficient in the diagnosis of mastitis for all classes of micro-organisms (80.0% vs. 79.9% for CPS, 82.0% vs. 71.5% for CNS, 82.2% vs. 72.0 % for coliforms, and 80.0% vs. 72.2% for other micro-organisms due to greater specificity when compared with SCC (81.6% vs. 71.2%. It is concluded that the test SCC offered so far, better diagnostic sensitivity for detection of ovine mastitis for most micro-organisms, providing greater security for the screening of cases in the herd which, in the future, may facilitate the effectiveness of disease control measures.

    Mastocytosis is a rare disease characterized by a pathological increased of mast cells in one or more tissues, particularly in the skin, bone marrow, liver, spleen, lymph nodes and gastrointestinal tract. Cutaneous mastocytosis represents over 90% of cases found with predilection in children. The aim of the paper was to summarize the authors' clinical, histopathological and immunohistochemical observations on patients with cutaneous mastocytosis. We present four cases of cutaneous mastocytosis, sporadic form, customized by clinical presentation and age of onset: two installed in the neonatal period, a case with onset in infancy and another in adulthood. For the assessment of the severity and the effectiveness of the treatment, we used SCORMA Index. We performed in each patient histopathological examination of the skin (Hematoxylin-Eosin and Giemsa stains), the dosage of mediators (serum tryptase level, serum histamine levels, urinary histamine metabolites) and the balance of expansion (complete blood cell count, liver biological investigations, abdominal ultrasound, skeletal radiography, chest radiography). For the adult with mastocytosis, we performed abdominal scanner and cytological study of the bone marrow. Following investigations carried out in each case, we mentioned the diagnosis of cutaneous mastocytosis, and also excluded several diseases confounded by clinically and histologically aspect. Considering the fact that the balance expansion was negative, we excluded the diagnosis of systemic mastocytosis. The presence of anemia and protein energetic malnutrition in children with mastocytosis involves carrying out balance extension for the exclusion of a systemic form of the disease. Histopathological examination of the skin using special stains, the dosage of mediators (serum tryptase level, serum histamine levels, urinary histamine metabolites) and balance expansion establish the diagnosis of cutaneous mastocytosis and also exclude many confusions because of the clinical presentation.

    Tatooing has been practiced for thousands of years. It has become a common practice for people of Western countries in the last 10-20 years, where approximately 3-5% of the population has at least one tattoo. Various pigmented substances introduced into the skin may cause the occurrence of adverse irritative, immunological, infectious or other reactions of the skin. We present three clinical cases with adverse reactions after tattooing.
