    Full Text Available Introduction Acute calculous (obstructive cholecystitis develops as a consequence of cystic obstruction and obstruction of bile flow into choledochus. Most often it is a result of impacted gallstones in Hartman's pouch or the cystic duct. Their direct pressure on gallbladder mucosa causes ischemia, necrosis and ulceration with consequential wall edema and obstructed venous flow. This mechanism is further increasing and spreading the inflammatory process. Ulcerations may be that extensive, that mucosa is highly recognizable on the microscopic preparation. Leukocyte infiltration of all segments occurs. Results of necrosis are as follows: perforation with pericholecystic abscess formation, fistulization or biliary peritonitis. Aim The aim of this investigation was to use microbial sensitivity tests in order to establish possibilities of antibiotic therapy in patients with acute cholecystitis. Material and methods Using random sampling a total of 240 patients with acute cholecystitis were included in the investigation. They were all treated at the Clinic of Abdominal and Endocrine Surgery of the Clinical Center Novi Sad in the period 1997-1999. All patients underwent bacteriological examination and were coherent in regard to sex and age. Microbial sensitivity tests analyzed two groups of bacteria: Group I Escherichia coli, Klebsiella and Staphylococcus and Group II: other isolated bacteria (Citrobacter, Enterobacter, Enterococcus, Proteus, Pseudomonas Serratia and Streptococcus. Results In our material Escherichia coli was isolated in most patients - 32 (55.17%, Klebsiella and Staphylococcus in 6 (10.34% patients and Streptococcus in 4 (6.90%, whereas other bacteria were infrequent (Citrobacter and Serratia in 3.45%, Enterobacter, Proteus and Pseudomonas in 1.75%. Thus, E. coli, Klebsiella and Staphylococcus were established in 75.85% of bacteriologic findings, and all the rest in 24.15%. Assessment regarding premedication with antibiotics started

    Portable, single-room humidifiers are commonly used in homes for comfort and health benefits, but also create habitats for microbiology. Currently there is no information on home humidifier microbiology aside from anecdotal evidence of infection with opportunistic pathogens and irritation from endotoxin exposure. To obtain a broader perspective on humidifier microbiology, DNAs were isolated from tap source waters, tank waters, and biofilm samples associated with 26 humidifiers of ultrasonic and boiling modes of operation in the Front Range of Colorado. Humidifiers sampled included units operated by individuals in their homes, display models continuously operated by a retail store, and new humidifiers operated in a controlled laboratory study. The V1V2 region of the rRNA gene was amplified and sequenced to determine the taxonomic composition of humidifier samples. Communities encountered were generally low in richness and diversity and were dominated by Sphingomonadales, Rhizobiales, and Burkholderiales of the Proteobacteria, and MLE1-12, a presumably non-photosynthetic representative of the cyanobacterial phylum. Very few sequences of potential health concern were detected. The bacteriology encountered in source waters sampled here was similar to that encountered in previous studies of municipal drinking waters. Source water bacteriology was found to have the greatest effect on tank water and biofilm bacteriology, an effect confirmed by a controlled study comparing ultrasonic and boiler humidifiers fed with tap vs. treated (deionized, reverse osmosis, 0.2 μm filtered) water over a period of two months.

    1983-01-01

    Although by 1931 I. Ph. Semmelweis' achievements and the tragedy of his life had been given their due place in the history of mankind, Alexander Fränkel, formerly Theodor Billroth's assistant and later his biographer, critically stated that the discoverer of the causes of puerperal fever should have defended his discovery with facts rather than with fanaticism. It was only a few years after Semmelweis' death, for instance, that Billroth made laborious experiments. Billroth's work on Coccobacteria had important implications and even influenced Robert Koch, although his hypotheses did not really predict the pathogenic and specific nature of microbes. In 1847 Semmelweis postulated his theory; ie, that the pathological-anatomical changes which he observed in the bodies of the women who died in childbed, in their newborn infants, and in the autopsy findings on his friend Jakob Kolletschka were an entity, morphologically and clinically. He summed them up under the concept of pyemia. Even though Semmelweis was continually abhorred by the evident statistics and would have been able to prove his discovery through animal experiments, he primarily took to the pen to defend his opinion vehemently. Only the clinical facts proved him right during his lifetime; the triumph of bacteriology which began after his death made him not only the "savior of mothers" but also a genial ancestor of bacteriology.

    2012-11-01

    In Australia, there are six Therapeutic Goods Administration-licensed clinical bacteriology laboratories providing bacterial and fungal bioburden testing of allograft musculoskeletal samples sent from 10 tissue banks. Musculoskeletal swab and/or tissue biopsy samples are collected at the time of allograft retrieval and sent to bacteriology laboratories for bioburden testing, in some cases requiring interstate transport. Bacteria and fungi may be present within the allograft at the time of retrieval or contaminated from an external source. The type of organism recovered will determine if the allograft is rejected for transplant, which may include all allografts from the same donor. Bacteriology staff also provides unpaid support of tissue banks through meeting involvement, consultations, licence-related activities, validations and research funded by their organisation and not part of any contractual agreement. Bacteriology laboratories and tissue banks must be compliant to the Code of Good Manufacturing Practice - Human Blood and Tissues and regulated by the Therapeutic Goods Administration. Clinical bacteriology laboratories also require mandatory accreditation to Standards Australia International Organisation for Standardisation (ISO) 15189:2009 medical laboratories - particular requirements for quality and competence, and may also attain Standards Australia/New Zealand Standard ISO 9001:2000 quality management systems certification. Bacteriology laboratories and musculoskeletal tissue banks are integral partners in providing safe allograft musculoskeletal tissue for transplant. PMID:22882601

    Full Text Available BACKGROUND Vesical calculi are the most common manifestation of lower urinary tract lithiasis. Urinary infections play an important role in aetiopathogenesis of vesical calculi. OBJECTIVE Aim of this study was proposed to establish the bacteriology of stone and urine in an attempt to evaluate the role of infection in the formation of stone. Associated factors like age, sex, site of infection, obstruction, diet were also evaluated. DESIGN Prospective cohort study. METHODS The patients were admitted in surgical ward as provisional diagnosed cases of vesical calculus, were subjected to investigations including CBC, RBS, urine analysis, renal function test, x-ray KUB region and ultrasonography. Patients who were fit for surgery, various surgical procedures were done. Gross examination and core culture of stone was done to establish their aetiology. RESULTS Ninety-four patients with vesical calculus were evaluated. Incidence of vesical calculus was 1.13%. Majority of cases were from rural areas (92.55%. Urinary tract infection was present in 37.2% of cases, majority of cases urine culture was positive (30.95%. Core culture of stone was positive in 18 cases (25.17%. E. coli was the predominant organism both in urine culture (19.04% and core culture of stone (25.71%. CONCLUSIONS There is significant association regarding the presence of vesical calculi and the development of urinary infections. E. coli was the predominant organism found both in urine and core culture of stone.

    Full Text Available Introduction: Foot infections are one of the major complications of diabetes mellitus and a significant risk factor for lower extremity amputation. Providing effective antimicrobial therapy is an important component in treating these infections. This study assesses the microbial isolates of patients with diabetic foot infections and their antibiotic susceptibility pattern. Materials and Methods: A retrospective study of 75 patients with diabetic foot infections admitted to RIPAS hospital between June 2008 and June 2010 was undertaken. Bacteriological specimens were obtained and processed using standard hospital procedure for microbiological culture and sensitivity testing. Results: Overall, 40 (54% patients had subcutaneous infections, 22 (29% had infected superficial ulcers, seven (9% had infected deep ulcers involving muscle tissues and six (8% had osteomyelitis. A total of 98 pathogens were isolated. Forty percent of the patients had polymicrobial infection, 39 (52% had single organism and 6(8% had no growth. Gram-negative bacteria (67% were more commonly isolated than gram-positive bacteria (30%. The three most frequently found gram-negative organisms were Pseudomonas aeruginosa (19.4%, Klebsiella pneumoniae (15.3%, and Acinetobacter spp. (10.2% and gram-positive organisms were Staphylococcus aureus (10.2%, Streptococcus pyogenes (7.1% and Methicillin resistant Staphylococcus aureus [MRSA] (7.1%. Vancomycin was found to be the most effective against gram-positive bacteria while amikacin was the most effective against gram-negative bacteria based on antibiotic testing. Conclusion: In 40% of diabetic feet infection was polymicrobial. Staphylococcus aureus and Pseudomonas aeruginosa were the most common gram-positive and gram-negative organisms respectively. This study helps us to choose the empirical antibiotics for cases of diabetic foot infections.

    Leprosy is a chronic infectious disease caused by a close relative of Mycobacterium tuberculosis: Mycobacterium leprae. There have been various beliefs in its etiology with two main concepts emerging: anticontagion and contagion. From ancient times through the early Middle Ages, the miasmatic theory of leprosy was the main anticontagion view. The development of histopathologic and cytologic studies in the second half of the 19th century provided a starting point to explain the etiology of leprosy bacteriologically. PMID:25432805

  20. Improvement of bacteriological quality of frozen chicken by gamma radiation

    International Nuclear Information System (INIS)

    The possible use of gamma irradiation at doses of 1.6 to 4.0 kGy to improve bacteriological quality of frozen chicken was investigated. The effects of gamma irradiation on salmonella viability in frozen chicken and on sensory quality of frozen chicken were also evaluated. D10-values for different isolated strains of salmonella in frozen chicken varied from 0.41 to 0.57 kGy. A dose of 4 kGy is required for a seven log cycle reduction of salmonella contamination in frozen chicken. Approximately 21 per cent of frozen chicken examined were contaminated with salmonella. Salmonella typhimurium, salmonella virchow, and salmonella java were predominant. Irradiation of frozen chicken at a minimum dose of 3.2 kGy eliminated salmonella, coliform, Escherichia coli, and Staphylococcus aureus and, in addition, reduced baterial load by 2 log cycles. Faecal streptococci was still present in a 3.2 kGy samples but in a very small percentage and the count was not over 100 colonies per g. Discoloring of chicken meat was noted after a 2 kGy treatment. The sensory quality of frozen chicken irradiated at 3 and 4 kGy tended to decrease during frozen storage but was within the acceptable range on a nine point hedonic scale even after eight months of frozen storage. Dosage at 3.2 kGy appeared to be sufficient for improving bacteriological quality of frozen chicken

  1. Laboratory automation in clinical bacteriology: what system to choose?

    Croxatto, A; Prod'hom, G; Faverjon, F; Rochais, Y; Greub, G

    2016-03-01

    Automation was introduced many years ago in several diagnostic disciplines such as chemistry, haematology and molecular biology. The first laboratory automation system for clinical bacteriology was released in 2006, and it rapidly proved its value by increasing productivity, allowing a continuous increase in sample volumes despite limited budgets and personnel shortages. Today, two major manufacturers, BD Kiestra and Copan, are commercializing partial or complete laboratory automation systems for bacteriology. The laboratory automation systems are rapidly evolving to provide improved hardware and software solutions to optimize laboratory efficiency. However, the complex parameters of the laboratory and automation systems must be considered to determine the best system for each given laboratory. We address several topics on laboratory automation that may help clinical bacteriologists to understand the particularities and operative modalities of the different systems. We present (a) a comparison of the engineering and technical features of the various elements composing the two different automated systems currently available, (b) the system workflows of partial and complete laboratory automation, which define the basis for laboratory reorganization required to optimize system efficiency, (c) the concept of digital imaging and telebacteriology, (d) the connectivity of laboratory automation to the laboratory information system, (e) the general advantages and disadvantages as well as the expected impacts provided by laboratory automation and (f) the laboratory data required to conduct a workflow assessment to determine the best configuration of an automated system for the laboratory activities and specificities.

  2. Improvement of bacteriological quality of frozen shrimp by gamma radiation

    International Nuclear Information System (INIS)

    The possible use of gamma irradiation at doses of 2 and 3 kGy to improve bacteriological quality of frozen shrimp was investigated. The effects of gamma irradiation on salmonella viability in frozen shrimp and on sensory quality of frozen shrimp were also evaluated. Treatment of frozen shrimp at 3 kGy reduced bacterial load by 2 log cycles and eliminated Enterobacteriaceae, E. coli, V. parahaemolyticus, and S. aureus. Coliform was still present in a 3 kGy treated samples but in a very small percentage and the count was less than 10 cell/g. Salmonella was not detected in either irradiated or non-irradiated frozen shrimp. A difference in radiation resistance was noted among five salmonella serotypes tested. S. lexington was the most resistant and S. anatum was the least resistant. Salmonella resistance was higher in frozen inoculated shrimp than in refrigerated inoculated shrimp. A dose of at least 4.2 kGy is required for a seven log cycle reduction of salmonella contamination in frozen shrimp. Off-flavors were produced in frozen shrimp irradiated at 4.2 kGy but diminished during subsequent frozen storage. However, irradiated frozen shrimp was of acceptable quality for at least four months. Dosage at 3 kGy appeared to be sufficient for improving bacteriological quality of frozen shrimp

    International Nuclear Information System (INIS)

    The usefulness of 14CO2 production from (U-14C) glucose, (U-14C) glutamate and (14C) formate as an index of raw milk quality was investigated. Development work showed that the volume of milk sample influenced the detection of radioactivity. The regression coefficient between Log10 of the inital bacterial count and the detection time (the time to reach 2000 cpm) in the presence of 0.13 μCi (U-14C) glucose/ml was -0.55 (n=119 samples) and the relationship was y=-0.11x+-0.46. The addition of 0.5 μCi (U-14C) glutamate and 0.5 μCi of (14C) formate decreased the detection times but did not result in greater predictability. Further study is required before the method could be used to determine the bacteriological quality of milk

    Two solid bacteriologic media were compared for cultivating Aeromonas spp. from piscine sources: the Rimler-Shotts (RS) medium and a starch-glutamate-ampicillin-penicillin-based medium (SGAP-10C) used for the recovery of Aeromonas spp. from water samples. The selective and differential capacities of the media were assessed March through October 1992 by recovery rate and phenotype of 99 isolates representing 15 genera of bacteria. Recovery frequency of Aeromonas spp. (n = 62) was similar at 97% on RS and 95% on SGAP-10C. The SGAP-10C medium proved to be more specific than RS toward Aeromonas species (P ≤ 0.005). Use of SGAP-10C at 24 C for 48 hr offers a better choice for the laboratory recovery of Aeromonas spp. from clinical fish specimens.

During storage time, sulfite-reducing Clostridia, coagulase-positive Staphylococci, and Escherichia colicounts never reached the tolerance limit established by the Brazilian legislation. However, Salmonellawas isolated from a Formula 2 sample on day 1, therefore, it was considered inappropriate for consumption. The shelf lives of Formulas 1 and 3 were below 12 and 8 days, respectively. If initial bacterial counts had been lower, the shelf life of the evaluated formulas would probably be longer. This study showed that ostrich meat trimmings can be successfully used in the production of ostrich linguiças, and that the formula containing ostrich meat as the only source of lean meat presented the longest shelf life.

  14. Irradiation of Dried Albumin from Cattle Blood: A Bacteriological Study

    International Nuclear Information System (INIS)

    The authors have undertaken a bacteriological study of irradiated albumin obtained from the blood of cattle. The albumin was obtained by drying blood collected in bulk at a slaughterhouse of the Argentine Meat Producers Corporation. The blood was separated by centrifuging into two fractions, white and red, the white fraction containing plasma, leukocytes and platelets, and the red fraction consisting of erythrocytes. The albumin is contaminated by microbes due to: (a) the impossibility of extracting the amount of blood involved (100 000 litres daily) under aseptic conditions; (b) transport of microbes in the blood during slaughter; (c) possible contamination by the blood of sick animals (veterinary examinations are carried out after extraction of the blood); (d) contamination caused by actual carcass processing. At present this material is used as a fertilizer, and for other industrial applications, but only in a minor degree for human nutrition. The reaction of the bacterial flora to gamma radiation was studied with the aid of a Gamma cell 220 apparatus operating in the dose range-0.5-4 Mrad. In the first test the whole material was irradiated, and total and differential counts performed for the purpose of identifying the different strains. The isolated bacterial flora was then studied together with the particular response, in each case, to different doses. The authors describe changes in the biochemical behaviour of some strains after irradiation. (author)

A PSB finding was considered positive at a level > or = 10(3) CFU/ml. There were no significant differences between the groups with respect to age, sex, proportion of smokers and ex-smokers or packs per year. The only spirometric measure that was significantly different was (FEV1/FVC, which was lower in the acute-phase group (p microorganism found most often in both groups. The mean CFU/ml level was 8,625 in stable patients and 17,375 in acute-phase patients (p = NS). A large proportion of stable patients (57.1%) with severe COPD harbor significant concentrations of germs as revealed by PSB sampling. Germ concentrations were found in a non significantly greater number of acute-phase patients, confirming the lack of congruence between clinical status and bacteriological condition. PMID:9072127

    Full Text Available Chronic Suppurative Otitis Media (CSOM is a condition of the middle ear that is characterized by persistent or recurrent discharge through a chronic perforation of the tympanic membrane from the middle ear cleft. Untreated cases of Chronic Suppurative Oti tis Media can result in a broad range of complications like mastoiditis, labyrinthitis, facial nerve paralysis and serious intracranial complications. In this study an attempt is made to know the aerobic bacteriology of Chronic Suppurative Otitis Media, wi th antimicrobial susceptibility testing of the bacterial isolates. The present prospective study was carried out on 50 patients presenting with Chronic Suppurative Otitis Media between January 2014 to December 2014 in the department of E.N.T, Basaveshwara Medical College Hospital and Research Centre, Chitradurga. The most common bacteria in Chronic Suppurative Otitis Media in this study was Pseudomonas aeruginosa (62% followed by Staphylococcus aureus (22%. Gentamicin was the most sensitive (100% antibio tic against Pseudomonas aeruginosa followed by Amikacin (96.77%. Ceftriaxone and Gentamicin were the most sensitive (100% antibiotic against Staphylococcus aureus followed by Amikacin (90.9%

    International Nuclear Information System (INIS)

    light of the lack of present data on the irradiation of fresh chicken sausage, the objective of this study is to evaluate determine the efficiency of this method as a process for reducing the microbial load via measurement of the bacteriology of the product before and after gamma radiation. 45 sample of chicken sausage(acquired directly from the poultry industry) were prepared divided in 3 treatments: the first is a control, the second and third using application of 1,5 and 3,0 kGy, respectively. The chicken sausages irradiated with a dose of 1,5 kGy did not have, statistically significant results apparent in the bacteriological measures. Samples irradiated with 3,0 kGy did experience statistically significant reductions. It is concluded that the irradiating the product with a dose of 3,0 kGy is more effective for the reduction of bacterial population, with the data in these trials indicating a 95,3% reduction in total coliforms, 100% removal of fecal coliforms, and 84,0% reduction of mesophiles, relative to the control samples.

    A study to assess the bacteriological quality of milk and ice cream was conducted using the direct plate count method and the methylene blue dye reduction test. A total of 105 milk and 95 ice cream samples were obtained form two factories (depots) and distributing supermarkets (outlets) in Harare. Under the methylene blue test, all milk and ice cream samples passed the hour and 2 hour tests respectively. However, 99% of the milk and 69% of the ice cream samples reduced the dye after 5.5 and 4 hrs respectively. The results from the direct plate counts revealed the presence of both pathogens and non-pathogens. The median plate counts in the milk and ice cream were found 400 cfu / ml and 100 cfu / ml respectively. Organisms isolated in both samples and in all outlets were similar, these included Bacillus spp. Coagulase Staphlococcus spp., microcuccus spp., Steptococcus spp., Diphthroids, Fusiform bacterial Klebsiella spp., and Citrobacter spp. No significant differences were found in the plate counts of the samples obtained from the depots and outlets for the milk (P = 0.542, df = 1)) and ice cream samples (P = 0.377, df = 1). Results further revealed that there was no significant difference in isolates obtained form strawberry ice cream (0.0096). The study has therefore, revealed that milk and milk product sold in various outlets in Harare contained a variety of bacteria of public health importance and also that the methylene blue dye reduction test is not reliable for the detection of bacterial contaminants in dairy products. It is thus suggested that the use of methylene blue dyes be adapted in combination with other tests such as the plate count in assessing bacterial contaminants in milk products. PMID:17650038

    Struvite renal stones are caused by infection of the urine with bacteria that synthesize the enzyme urease. Ammonium is released by the breakdown of urea by urease, the urine becomes highly alkaline, and magnesium ammonium phosphate (struvite) and carbonate apatite crystallize. Incorporation of the infecting bacteria within the developing stone, results in a focus of infection that is resistant to conventional antimicrobial therapy, and which is manifested clinically by repeated urinary tract infection caused by persistent bacteriuria. Extracorporeal shock wave lithotripsy (ESWL) currently is accepted as the election treatment for most renal calculi. This trial examines the bacteriologic aspects pre and post-ESWL. Eighty adult patients, 47 females and 33 males, without clinical signs of urinary tract infections (UTI) were submitted to urine cultures pre and post-ESWL. The first 50 patients underwent during and post-ESWL, 150 blood cultures, which all proved to be negative, confirming very low risk of generalized sepsis. No patient presented fever, chills or rigors pre or postprocedures. With respect to urine cultures 43 patients (52.5%) had a pre-ESWL UTI, in comparison to 49 (60%) who had a UTI post-ESWL. The distribution of organisms pre and post-ESWL was as follows: Proteus mirabilis (22/22), Escherichia coli (11/11), Pseudomonas aeruginosa (4/5), Klebsiella pneumoniae (2/2), Enterobacter cloacae (0/1), Alcaligenes odorans (1/2) Enterococcus faecalis (1/3), Staphylococcus saprophyticus (1/2) and Candida albicans (1/1). In this study 6 patients presented bacteriuria post-ESWL probably due to bacteria from inside the calculi. According to these results, the risk of bacteremia seems to be very low. In 60% of staghorn renal stones we could demonstrate a bacterial infection. PMID:7658975

    A total of 757 milk samples were taken from 57 farms throughout Wales as part of a mastitis investigation. Problem cows were selected using the most recent milk recording or, if these data were unavailable, the whole herd was assessed using the California mastitis test (CMT) and scored on a scale of 0 to 3. The affected quarter was identified using CMT. The results of the bacteriology were grouped into negative and positive culture. All contaminated samples were excluded. The CMT recording at the time of sampling, the infection status of the cow (new, first, chronic or repeat) as defined by national milk records and the number of quarters infected at the time of sampling were identified for negative and positive samples. Selecting quarters with a higher CMT score increased the likelihood of positive culture. Culturing from a sample with a CMT score of 3 was over three times more likely to yield a positive culture than a score of 1 (odds ratio [OR] 3.74, 95 per cent confidence interval [CI] 1.41 to 9.97) and 1.7 times more likely to yield a positive culture than a score of 2 (OR 1.70, 95 per cent CI 1.16 to 2.50). Culturing from a score of 2 was not statistically different from a score of 1 in terms of the likelihood that a positive culture would be identified (OR 2.20, 95 per cent CI 0.83 to 5.93). There was no statistically significant difference in the proportion of negative samples when comparing chronic, repeat, new and first infections or number of quarters infected. PMID:20228365

    Full Text Available Lack of well-stabilized biosolids is a basic problem for many municipal wastewater treatment plants in Iran. Disposed biosolids from west Ahvaz wastewater treatment plant were generally used for agricultural activities. Initial evidence showed that these biosolids were untreated and had the potential to transmit many pollutants to the environment and create hazards for public health, although anaerobic digester was selected for this wastewater treatment plant. The main objective of this research was to evaluate and optimize the bacteriological quality of biosolids by lime addition in west Ahvaz wastewater treatment plant. The stability and reuse potential of biosolids from existing anaerobic digester and lime added biosolids were investigated. Lime addition to biosolids was performed in the reactor with 30 L capacity. Averge amounts of fecal coliforms and viable helminthes ova in disposal biosolids from anaerobic digester were 1.3×1015 MPN / g of dry solids and 314 ova / 4 g of dry solids, respectively. By lime addition with the ratio about 0.265 g Ca (OH2 per g of dry solids, pH was not dropped under 12 and growth of fecal coliform was not detected after 30 days. In this regard, discharged biosolids from this plant was unstable and very dangerous for reuse or disposal. Lime addition could stabilize the biosolids and reduce fecal coliforms more than 99.99% and had concordance with class B of United State Environmental Protection Agency criteria. Lime-stabilized biosolids could hence be well used for reconditioning the poor soil and for covering of solid waste landfill-sites.

    Endometritis is an important cause of sub-fertility in mares. The critical indicator of reproductive success and financial return for commercial studs is live foaling rate. Endometrial bacteriology and/or cytology are used to diagnose endometritis and thus identify mares at risk of early embryonic death. However, mares with endometritis may conceive but then abort in late gestation. The aims of this study were to establish, as part of a standard breeding examination (1) whether a threshold percentage of uterine polymorphonuclear neutrophils (PMNs) exists above which a significant reduction in live foaling rate is evident; (2) the relationship of a positive bacteriology result to live foaling rate, and (3) the relationship of a combination of positive cytology and bacteriology result to live foaling rate. Guarded endometrial swabs (n=2660) were collected from 1621 Thoroughbred mares on 17 commercial stud farms by five veterinarians during a single breeding season. All mares were included regardless of age, history or parity. Cytological and bacteriological analyses were performed on each swab and subsequent live foaling rates recoded. Data were analysed by comparing 0%, ≥ 1%, ≥ 2%, ≥ 5% or ≥ 25% PMNs of total cells counted, or categories of bacterial growth to live foaling rates, using Pearson's chi-squared test. A threshold value of ≥ 1% PMNs, culture of a single bacterial isolate and a combination of both these parameters were associated with significantly reduced live foaling rates. Positive cytology alone, positive bacterial culture alone, or combined positive cytology and bacteriology were equally indicative of the likelihood of a mare producing a live foal. PMID:24035467

    Full Text Available The water quality of the Tepalcingo-Axochiapan aquifer, Mexico was determined. Six samplings were carried out, taking samples from eight wells before chlorine and one spring. Two bacteriological and 11 physicochemical parameters were analyzed. Most of the wells and spring presented hard water. The wells showed higher concentrations of dissolved solids at lower altitudes, exception of the spring. Discriminate analysis and the Mahalanobis distances showed that the spring had the biggest differences with respect to the other wells. Bacteriologically the spring and a well are not suitable for amusement activities and physicochemically three wells are not suitable as a source of drinking water. The lack of sanitation and drainage in some areas may be causing deterioration of water quality in the aquifer in such areas.

    Full Text Available The work is based on a study of prostate stones obtained by transurethral resection of the prostate in 5 patients with benign prostatic hyperplasia in combination with chronic calculous prostatitis. Stones have been investigated by scanning electron microscopy and X-ray microstructural analysis, as well as a comparative study of bacteriological swabs from the surface of the stones after ultrasonic treatment of stone and without it. Pretreatment ultrasound prostate stones before sowing on nutrient medium swabs improves bacteriological diagnosis, which may be due to the dispersion of biofilms and exit vegetative forms of bacteria from it. This feature can serve as ultrasound theoretical justification for its use to improve the efficiency of diagnosis of various forms of prostatitis.

    Despite the growing demand of tourism in Malaysia, there are no resolute efforts to develop beaches as tourist destinations. With no incentives to monitor public beaches or to use them in a sustainable manner, they might eventually degenerate in quality as a result of influx of pollutants. This calls for concerted action plans with a view to promoting their sustainable use. The success of such plans is inevitably anchored on the availability of robust quality monitoring schemes. Although significant efforts have been channelled to collation and public disclosure of bacteriological quality data of rivers, beach water monitoring appears left out. This partly explains the dearth of published information related to beach water quality data. As part of an on-going nation-wide surveillance study on the bacteriological quality of recreational beaches, this paper draws on a situation analysis with a view to proffering recommendations that could be adapted for ensuring better beach water quality in Malaysia.

The difficulty involved in the preparation of blood plates and the results obtained with this medium prohibit its complete acceptance as a substitute for agar in routine solid media. However, it could be a suitable substitute for agar in all other routine bacteriological media. PMID:596869

    Full Text Available Abstract Background Urban water sources of Khamis Mushait Governorate, southwestern Saudi Arabia, were studied to assess their bacteriological characteristics and suitability for potable purposes. A cross-sectional epidemiological method was adopted to investigate the four main urban water sources (i.e. bottled, desalinated, surface, and well water. These were sampled and examined between February and June 2007. Results A total of 95 water samples from bottled, desalinated, surface, and well water were collected randomly from the study area using different gathering and analysing techniques. The bacteriological examination of water samples included the most probable number of presumptive coliforms, faecal coliforms, and faecal streptococci (MPN/100 ml. The results showed that the total coliform count (MPN/100 ml was not detected in any samples taken from bottled water, while it was detected in those taken from desalinated, surface, and well water: percentages were 12.9, 80.0, and 100.0, respectively. Faecal coliforms were detected in desalinated, surface, and well water, with percentages of 3.23, 60.0 and 87.88, respectively. About 6.45% of desalinated water, 53.33% of surface water, and 57.58% of well water was found positive for faecal streptococci. Colonies of coliforms were identified in different micro-organisms with various percentages. Conclusion Water derived from traditional sources (wells showed increases in most of the investigated bacteriological parameters, followed by surface water as compared to bottled or desalinated water. This may be attributed to the fact that well and surface water are at risk of contamination as indicated by the higher levels of most bacteriological parameters. Moreover, well water is exposed to point sources of pollution such as septic wells and domestic and farming effluents, as well as to soil with a high humus content. The lower bacteriological characteristics in samples from bottled water indicate that

    Bacteriology testing is mandatory for quality control of recovered cardiovascular allografts (CVA). In this paper, two different bacteriology examinations (A tests) performed before tissue antibiotic decontamination were compared: transport solution filtration analysis (A1) and tissue fragment direct incubation (A2). For this purpose, 521 CVA (326 heart and 195 artery tissues) from 280 donors were collected and analyzed by the European Homograft Bank (EHB). Transport solution (A1) tested positive in 43.25 % of hearts and in 48.21 % of arteries, whereas the tissue samples (A2) tested positive in 38.34 % of hearts and 33.85 % of arteries. The main species identified in both A1 and A2 were Staphylococcus spp. in 55 and 26 % of cases, and Propionibacterium spp. in 8 and 19 %, respectively. Mismatches in bacteriology results between both initial tests A1 and A2 were found. 18.40 % of the heart valves were identified as positive by A1 whilst 13.50 % were considered positive by A2. For arteries, 20.51 % of cases were positive in A1 and negative in A2, and just 6.15 % of artery allografts presented contamination in the A2 test but were considered negative for the A1 test. Comparison between each A test with the B and C tests after antibiotic treatment of the allograft was also performed. A total decontamination rate of 70.8 % of initial positive A tests was obtained. Due to the described mismatches and different bacteria identification percentage, utilization of both A tests should be implemented in tissue banks in order to avoid false negatives. PMID:26662518

    The relationship between dental plaque and gingivitis was verified. Nonspecific gingivitis is an inflammatory process, frequently caused by enzymes and toxins liberate by bacteria form dental plaque. Loose plaque has come under a great deal of investigation because of its role in attachment loss. The current methods used in the treatment of non specific gingivitis encompass the use of antibiotics and conventional surgical techniques. Treating gingivitis with laser energy may further reduce the gingival inflammation and decrease the wound healing time. The lack of correlation between the quantity of dental plaque and the intensity of gingivitis determined us to study the effect of Nd:YAG pulsed laser in reduction of gingival inflammation and wound healing. The aim of this work is to evaluate clinically the anti- inflammatory and wound healing effect of pulsed Nd:YAG laser and to compare the appearance and the levels of the bacteria in the supergingival and subgingival plaque in adolescents with tooth crowding after Nd:YAG laser. The experimental procedure consisted of a clinical and bacteriological study which was undertaken in 20 patients presenting moderate gingivitis. A group of 10 patients was the subject of a bacteriological study and the other group of 10 was used for clinical and histological examination. For each group the clinical criteria of evaluation were: the gingival index, papillary bleeding index, spontaneous aches. Each patient was tested before and after laser exposure or conventional therapy for bacteriological analyses. The results prove that early gingivitis exposure to laser registers a decrease of bacterial colony number and absence of loss of attachment as compared to the application of the conventional treatment. Clinical study has shown that the combination of scaling and root planning with laser therapy is enough to provide improvement in clinical indices and reduction in the number of bacterial colonies.

    We perform an exhaustive, taxon by taxon, comparison of the branchings in the composition vector trees (CVTrees) inferred from 432 prokaryotic genomes available on 31 December 2006, with the bacteriologists' taxonomy-primarily the latest online Outline of the Bergey's Manual of Systematic Bacteriology. The CVTree phylogeny agrees very well with the Bergey's taxonomy in majority of fine branchings and overall structures. At the same time most of the differences between the trees and the Manual have been known to biologists to some extent and may hint at taxonomic revisions. Instead of demonstrating the overwhelming agreement this paper puts emphasis on the biological implications of the differences.

    Full Text Available The main objective of this research was to study the marine bacteriology of the coast of North Sulawesi. The study was accomplished by calculating the abundance of coliform, heterotrophic, and pathogenic bacteria, and analyzing the coexistence relationship between bacteria and phytoplanktons. This research, which included the sampling and laboratory works, has been carried out on 25 - 28 October, 2000. The results suggested that the abundance of each bacteria was as follows: coliform bacteria range between 227-5940 cfu/100 ml with averages 1814.1 cfu/100 ml, found in all stations; heterotrophic bacteria range between (1-82 x 103 cfu/ml with averages 12.1 x 103 cfu/ml, it was high density and has association with phytoplankton Trichodesmium thieubautii. It was also found 6 species of pathogen bacteria e.g. Aeromonas, Citrobacter, Proteus, Pseudomonas, Yersinia and Shigella. The presence of coliform and pathogen bacteria was indicator of low quality of the seawater in the sampling area. Based on bacteriological study, the North Sulawesi Coastal is not suitable for aquaculture and need treatment and controlled for further coastal exploitation.

    Full Text Available Neonatal septicemia is an important cause of morbidity and mortality. The present study was undertaken to determine the bacteriological profile and antimicrobial susceptibility pattern of prevalent pathogens isolated from the blood of septicemic neonates from Neonatal Intensive Care Unit (NICU. A total of 180 blood samples of septicemic neonates were studied bacteriologically. Antimicrobial susceptibility testing was done by the Kirby Bauer disc diffusion method in accordance to Clinical Laboratory Standards Institutes (CLSI guidelines. 26.6% (48 out of 180 cases of septicemia could be confirmed by blood culture. Of these, 66.7% cases were of early onset septicemia (EOS and 33.3% were of late onset septicemia (LOS. Klebsiella pneumoniae was the predominant pathogen (35.4% among the Gram-negative pathogens and Staphylococcus aureus (22.9% was the predominant Gram-positive pathogen. 28% of K. pneumoniae and E. coli isolates were extended spectrum beta-lactamase (ESBL producers. 18.1% of the Staphylococcus isolates were methicillin-resistant S. aureus (MRSA. Multi-drug-resistance pattern was observed with all the isolates. Ciprofloxacin and aminoglycosides were the most effective drugs against Gram-positive and Gram-negative isolates. This study highlights the predominance of Gram-negative organisms in causing neonatal sepsis and emergence of multi-drug-resistant strains in our set up.

    Full Text Available The bacteriological quality of three major food outlets in Rufus Giwa Polytechnic, Owo, was assessed using standard bacteriological methods. Swabs of hands of food vendors, table and plates in these outlets were assessed for total bacterial count, total coliform count and total E. coli count. A total of 789 bacterial colonies were isolated from hands of food handlers, tables and plates used for eating in the outlets. Eleven genera of bacteria were isolated and identified, they were; klebsiella sp, Enterobacter sp , Staphylococcus sp, Proteus sp, E. coli Salmonella sp, Micrococcus sp, Bacillus sp, Pseudomonas sp, Streptococcus sp and Serratia sp when their morphology and biochemical characteristics were compared with standard reference organisms. The presence of these bacterial isolates has been attributed to ineffective washing technique , rare changing of water used for washing plates and poor personal hygiene of the food handlers which could be enhanced by regular monitoring and supervision of the canteens by the authorities on food safety practices and regular education on food and personal hygiene.

    Swimming pools have been identified as posing some public health risks to users due to either bacterial or chemical contamination. As a result, maintaining good swimming pool water quality is an important issue in preventing health risks for bathers. This study aimed to evaluate the bacteriological quality of some swimming pools in Alexandria and to investigate the prevalence of Staphylococcus aureus (S. aureus) in water samples. A total of 120 water samples from 10 swimming pools were collected. Bacteriological analysis included heterotrophic plate count (HPC) using pour plate method; enumeration of total coliforms (TC), Escherichia coli (E. coli) and S. aureus by membrane filtration technique. Antimicrobial susceptibility testing was performed on isolated S. aureus. Residual chlorine and pH were measured at swimming pools side. HPC was the least complying microbial parameter, followed by TC. S. aureus was recovered from 18 samples; 9 isolates were methicillin resistant S.aureus (MRSA), compared to E. coli that was detected in 7 samples. HPC and TC showed statistically significant correlations with all investigated parameters. In conclusion, the examined pools showed poor quality regarding all examined parameters collectively according to the Egyptian guidelines, which necessitates implementation of proper measures to ensure safer environment in swimming pools.

  15. Bacteriological evaluation of refrigerated vacuum and air-packed chicken fillets treated with irradiation

    International Nuclear Information System (INIS)

    Chicken meat is a nutritious food, rich in essential aminoacids and much appreciated by a large fraction of the population. However, it is also highly perishable, typically having a shelf life of 5 to 7 days in refrigeration, depending on the initial microbiological load. Irradiation has been efficiently used to improve safety and extend the shelf lives of many meat products. Its use in combination with refrigeration and exclusion of oxygen is known to greatly enhance the sanitary quality of meat. This work investigated the bacteriological effects of radiation doses of 0; 2.0 and 3.0 kGy on vacuum- and air-packed chicken fillets kept at 1 deg C for up to 18 days. Bacteriological analyses that included enumerating and counting indicated that both the lag phase of the bacterial growth and the shelf life of the samples increased with dose. It was observed that exposure to 3.0 kGy extended the initial 5-day shelf life of the air-packed fillets to 10 days while prolonging to 12 days the shelf life of the vacuum-packed ones. Among the species of bacteria monitored, the lactic bacteria were found to be the most resistant to gamma radiation while coliforms were the most sensitive. (author)

    International Nuclear Information System (INIS)

    Chicken carcasses dipped in whey fermented by Streptococcus thermophilus, lactic acid solution or water and irradiated at 2.5 kGy by 60Co were evaluated for bacteriological quality on day 1, day-3 and at 3-day intervals for an 18-day storage (4 degrees C) period. Unirradiated carcasses treated similarly were used as control. Gram negative bacteria, Yersinia and Campylobacter counts were significantly (p0.01) lower in irradiated samples, but no significant (p0.05) differences were observed ammong the dipping solutions. Salmonellae were completely eliminated in irradiated samples. Whey fermented by S. thermophilus reduced the proportion of Salmonella contaminated carcasses from 67% to 20%. As evidenced by the bacterial counts the shelf-life was found to be 15 days for irradiated carcasses compared to about 6 days for the unirradiated samples

    Histological and clinical studies have been made on comparable burn wounds covered with either boiled potato peels affixed to gauze bandages or gauze dressings alone; both dressings were applied over a thin layer of 5 per cent silver sulphadiazine. Compared with treatment with plain gauze dressings, the application of the potato peel dressing reduced or eliminated dessication, permitted the survival of superficial skin cells and hastened epithelial regeneration. Bacteriological studies showed that the potato peels had no intrinsic antibacterial activity, the wounds beneath both dressings showing either no growth or, on most occasions, the same bacterial species. The easy availability of potato peels and gauze bandages on to which they can be affixed, the simplicity of the preparation of this dressing, the ease of sterilization and its low cost of production make this the dressing of choice for burn wounds in our developing country.

    Full Text Available Infections are encountered by all surgeons post operatively. Sometimes post - operative infections lead to death. Death from infection was so common after compound fractures, amputations and gunshot wounds. Now a day’s surgical site infections (SSI are main ly due to hospital acquired infections and irrational use of antibiotics, so bacteriological profile of surgical site infections and their antibiogram is an essential compliment to surgical skills. OBJECTIVE: The objective of the present study is to isolat e the aerobic bacteria which are associated with the post - operative surgical site infections and to determine the frequency, with which various pathogens are causing surgical site infections and their antibiogram. MATERIALS AND METHODS: Swabs were collecte d from the local wound site of 100 clinically diagnosed cases of surgical site infections in the wards of surgery, orthopedics, gynecology and obstetrics, Andhra Medical College, Visakhapatnam, Andhra Pradesh. They were processed and different bacteria wer e isolated by using standard bacteriological procedures and biochemical reactions. Antibiotic susceptibility testing was performed by Kirby Bauer disc diffusion test. RESULTS: Coagulase positive staphylococci emerged as a commonest organism with an inciden ce of 32% followed by Pseudomonas, Escherichia coli. Methicillin was found to be the most effective antibiotic against various Staphylo co ccal strains, followed by Clindamycin. All the staphylococcal strains iso l ated were resistant to Penicillin and Erythro mycin. Amikacin was found to be effective against Pseudomonas with sensitivity of 37.5%. All strains were resistant to Norfloxacin. Several isolates were found to be multi - drug resistant, and it was observed more in Gram negative bacterial isolates.

Objective: This study was conducted to assess the bacteriological quality and food safety practices of a municipal school food program (MSFP in Jequitinhonha Valley, Brazil. Materials and methods: A checklist based on good manufacturing practices (GMP for food service was used to evaluate food safety practices. Samples from foods, food contact surfaces, the hands of food handlers, the water supply and the air were collected to assess bacteriological quality in establishments that comprise the MSFP. Results: Nine (81.8% establishments were classified as poor quality and two (18.2% as medium quality. Neither Salmonella nor Listeria monocytogenes were detected in food samples. Coliforms, Escherichia coli and Staphylococcus aureus were detected in 36 (52.9%, 1 (1.5% and 22 (32.4% of the food samples and in 24 (40.7%, 2 (3.3% and 13 (22.0% of the food contact surfaces, respectively. The counts of coliforms and Staphylococcus aureus ranged from 1 to 5.0 and 1 to 5.1 log CFU/g of food, respectively. The mean aerobic mesophilic bacteria count was 3.1 log CFU/100 cm² of surface area. Coliforms, E. coli and S. aureus were detected on the hands of 33 (73.3%, 1 (2.2% and 36 (80% food handlers, respectively. With regard to air quality, all the establishments had an average aerobic mesophilic count above 1.6 log CFU/cm²/week. Conclusions: The results indicate the need to modify the GMP used in food service in MSFP in relation to food safety, particularly because children served in these establishments are often the most socially vulnerable.

    Full Text Available Kitui town, a small but fast growing town in arid south-eastern Kenya faces unreliable water supply and residents are highly dependent on shallow wells as the main source of water for domestic use. A study was carried out to assess the physical-chemical and bacteriological quality of water from shallow wells within the town’s main residential areas. 96 water samples were collected from 8 main residential estates within the town between May and July 2011 and analysed for physical-chemical characteristics and bacterial quantity and species. Water analysis revealed presence of 9 pathogenic genera including Salmonella, Escherichia coli, Vibrio, Listeria, Staphylococcus, Streptococcus, Enterobacter, Klebsiella and Pseudomonas. Multiple-tube fermentation technique was used to enumerate coliform bacteria in water. Total aerobic bacterial load ranged from 3.70 x102 to 2.352 x103 CFU/ml. E. Coli was isolated from Majengo and Mjini estates only and the bacterial load estimated as 1.10 x102 CFU/ml and 0.20 x102 CFU/ml respectively while Salmonella sp. was isolated from water samples from Kunda Kindu, JICA and Mjini estates. Conductivity and pH levels were above World Health Organization acceptable levels for drinking water in all samples. All samples tested did not meet the WHO bacteriological standards for drinking water. The presence of Salmonella, Vibrio, Listeria and E. Coli should particularly raise serious public health concerns over the quality of the town’s shallow wells water. Intervention measures including creating awareness and educating residents on shallow well construction, citing and care, boiling of water and improving sanitation should be urgently instituted. There is also need to construct sewerage works for the rapidly expanding Kitui town to reduce incidences of contamination from septic tanks.

    The objectives of this study were to characterize clinical, intrauterine, bacteriologic and cytologic changes during the first month after parturition in healthy dairy cows and in cows with subclinical endometritis (SE) or clinical endometritis (CE). Furthermore, risk factors related to clinical bacteriologic and cytologic findings were determined. A total of 170 calvings were enrolled, and intrauterine samples were collected on Days 0, 3, 9, 15, 21, and 28 postpartum using the cytobrush technique. The presence of Escherichia coli and Trueperella pyogenes was determined by Fourier transform infrared spectroscopy. The cows were categorized according to their uterine health status (UHS) on Day 21 as healthy (clear or absent vaginal discharge and cows with SE and CE showed a greater bacterial growth density (BGD) than those from healthy cows. The BGD tended to be affected by the interaction of time by UHS (P = 0.057). Differences between healthy, SE, and CE cows were found from Day 3 to the last sampling day. Furthermore, the percentage of PMN differed between healthy, SE, and CE cows and was affected by time in a cubic way (decrease/increase/decrease). Overall, E coli was found in 25.4% of the samples, and T pyogenes was identified in 30.2% of the samples. The risk for CE was increased by BGD and the presence of T pyogenes. Conversely, the presence of E coli had no effect on the risk of CE or the risk of SE. The risk for an infection with T pyogenes was greater in the first-parity cows and in cows with assisted calving. In conclusion, changes in BGD and proportion of PMN varied with the UHS (healthy, SE, and CE), which was affected by the presence of T pyogenes but not E coli. PMID:25270027

Of the 50 Paw-paw pre-cuts were: Escherichia coli 21 (14.00%), Staphylococcus aureus 10 (6.67%), Salmonella species 3 (2.00%), Proteus species 4 (2.67%), Enterobacter aerogenes 1 (0.67%) were isolated. The findings in this study have shown that the food vendors failed to adopt adequate hygiene for food handling and thus, suggest that the quality of all the pre-cut fruits sold at the retail outlets were not bacteriologically satisfactory. The public health risks associated with these pre-cut fruits may suggest that these fruits could serve as the vehicles for foodborne illnesses. This study has shown the need to educate the vendors on how to protect utensils and fruits to avoid contamination and spoilage. PMID:20000065

    Full Text Available This article explores the relation between bacteriology and medical geography in the 19th century in Colombia, following the case of fevers. Through this, it explains how historiography has approached the relation between bacteriology and medical geography, and analyzes said relation in the medical research pertaining to yellow fever, fevers of the Magdalena River, and malaria in the 1880s. Finally, it shows that, instead of passively incorporating bacteriology, the physicians fought to combine it with medical geography, incorporating elements of both approaches, keeping them in tense separation, or rejecting one in favor of the other.

    Full Text Available In this study fishburger samples obtained from tilapia minced meat and surimi retrieved from fillet frames - filleting process waste - have been assessed. Four different preparations of fishburger were made. Chemical analyses was performed for protein, lipids, moisture and ash assessments, as well as bacteriological analyses through mesophilic aerobic heterotrophic and psychrotrophic bacteria counts, isolation and identification of Salmonella spp., coagulase-positive Staphylococcus and fecal coliforms. Instrumental measurements were also carried out for texture and tested sensory acceptance. The costs of the ingredients used in the preparation of formulas were also assessed. Microbiological standards, established by current regulations, were met by all samples. No significant gap (P>0.05 was detected among the percentage of protein, moisture and ashes, while a significant gap (P<0.05 was verified for lipids. A significant gap (P<0.05 for the instrumental measurements of texture was also observed. Both surimi and minced meat fishburger presented good acceptance on sensory tests for taste, texture and overall impression. The use of smoked fish flavoring and surimi caused a considerable increase in costs due to ingredient acquisition. This study shows a positive result for the industrialization and consumption potential of fishburgers made of minced fish retrieved from fillet frames.

    Full Text Available Aim: The study was carried out to investigate the microbiological quality of packaged drinking water marketed in Jaipur city. Material and Methods: In the present study 'twenty' drinking water samples (15 water bottles and 5 sachets of different brands purchased randomly, were evaluated to access the water quality on the basis of different bacteriological parameters. Result: Out of twenty, 50% samples were found unsatisfactory in standard plate count. Psychrophillic, coliforms, E. coli and staphylococcal counts revealed that 25%, 45%, 20%, and 5% samples respectively were found unfit for human consumption as per Bureau of Indian Standards (BIS of drinking water. On the basis of results of overall microbiological assessment 55% of samples proved to be unfit for consumption. All brands of water sachet (100% had high coliforms count which indicates faecal contamination. Amongst those sachets two brands (40% had presence of E. coli and all the sachet water brands fell below drinking water standards while out of fifteen brands of bottled water 6 samples contained higher microbiological value hence unfit for human consumption. Conclusion: Local brands of packaged drinking water were found unfit for human condumption. So it is suggested that government should intensify the efforts in the monitoring of activities in this rapidly expanding industry with a view to supply potable and wholesome water to the public.

    International Nuclear Information System (INIS)

    Anthropogenic waste and water bacteriological quality were surveyed twice a year in 2000 and in 2002 at five coastal marine environments in Costa Rica, one in the Caribbean (Bahia de Moin) and four in the Pacific (Bahia de Culebra, Golfo de Nicoya, Estero de Puntarenas, Bahia de Golfito). The most probable number (MPN)/100 mL of coliform bacteria was calculated after incubation series of five test tubes. A total of 14 coastal and two river water samples were collected in the Caribbean, and 32 coastal, nine estuarine and one tap water samples in the Pacific, plus 25 samples investigated for Escherichia coli in 2002. The means of 2 MPN/100 mL in June 2000 and 17 MPN/100 mL in May 2002, and faecal coliforms <2 MPN/100 mL in June 2000 and 4 MPN/100 mL in May 2002.

    Twenty-eight designated swimming beaches, four informal swimming areas, two canoe launching or landing sites, and two additional sites on a canoeing stream were sampled at least ten times each during 30-day sampling periods in the summer of 1992. One designated swimming beach, one informal swimming area, and two canoe launching or landing sites exceeded the recommended criterion of geometric mean concentrations of fecal coliform bacteria of 200/100 mL. In addition to these four sites, five designated swimming beaches and one informal swimming area exceeded the US Environmental Protection Agency (EPA) recommended criterion by having more than 10 percent of the fecal coliform samples with concentrations greater than 400/100 mL. Rainfall was an important factor for these six sites and the four sites that did not meet the geometric mean criterion. Some sampling sites are affected by rainfall more than others. When bacteria concentrations increase after rainfall, it indicates that site is vulnerable to contamination from nonpoint sources of pollution. Recreational use of these sites following rainfall is discouraged. If samples collected within 24 hours of rainfall (one-half inch or more) are excluded, all-but one of the ten sites have better bacteriological water quality, and two meet both the geometric mean and maximum concentration criteria. Five canoe access locations on the Bear Creek floatway, plus one site upstream and another downstream of the floatway were sampled eight times each during 1992. All seven sites met recreation criteria.

    Dog bite wounds are a common reason for dogs requiring veterinary care, but there is surprisingly little data on the bacteriology of bite wounds. A prospective study was performed on dogs with various grades of bite wound to identify the bacteria present in these wounds. Swabs were collected from all wounds for bacterial culture and cytology. All swabs were cultured aerobically and anaerobically and all aerobic cultures were evaluated for antibiotic susceptibility using the Kirby Bauer disk diffusion test. Fifty dogs with 104 bite wounds, inflicted within the previous 72h, were included. The victims were predominately intact male small breed dogs. Of the 104 wounds, 21 were judged by cytology to be infected and 83 non-infected. Infected wounds were significantly more likely to culture positive (p=0.02). Sixteen percent of wounds showed no growth. Sixteen percent grew aerobes, 1% anaerobes and 67% a mixture of aerobes and anaerobes. Pasteurella canis and pyogenic streptococci were common in infected wounds, whereas Bacillus spp., Actinomyces spp. and the oral streptococci were usually found in contaminated wounds. Three anaerobic genera were cultured, namely, Prevotella, Clostridium and Peptostreptococcus. One case represented the first isolation of Capnocytophaga canimorsus in an infected dog bite wound. Although no single antibiotic therapy was considered to be effective against all the bacteria, amoxycillin plus clavulanic acid, 1st and 3rd generation cephalosporins ampicillin or amoxycillin and potentiated sulphonamides gave the best in vitro sensitivity results.

    Full Text Available Water is essential for life and in most parts of the world including Ghana it is used for various activities such as drinking, bathing and recreational purposes. The objective of this study was to assess the bacteriological quality of swimming pools’ water in the Accra Metropolis. Five swimming pools were selected randomly and a research team visited the pools to collect water samples and at the same time administer short questionnaires about the characteristics of the pools. The average number of swimmers, swimming bathing loads, average age group of pool users, methods of disinfection, type of chlorine used, recycling, and treatment of the water before and after use were investigated. During the visit, water samples were collected for total coliform, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus counts using the Membrane Filtration (MF method and cultured on chromogenic media. Most (60% of the selected swimming pools had a bathing load≤20 per day. The operators of the pools disinfect their pools’ water with chorine but majority (60% of the pool operators chlorinated their pools manually with powdered chlorine. The 20 water samples investigated show that 48% of swimming pools water was contaminated with S. aureus, 30.4% with Ps. aeruginosa , 20.9% with total coli form and 0.7% with E. coli. The E. coli count found in this study was very low indicating that the selected swimming pools were not feacally polluted at the time of sampling. It is recommended that future studies should use large sample sizes.

    2012-12-01

    Full Text Available Aquaculture is currently one of the fastest growing food production sectors in the world. Increase in nutrients and organic wastes lead to general deterioration of water quality. The problem of water quality is associated with both physical and chemical factors, as well as microbiological water quality. Heterotrophic bacteria play an important role in the process of decomposition of organic matter in water environment and indicate eutrophication process. Here we present our experience and knowledge on bacterial properties of marine water in the Adriatic fish farms with European sea bass (Dicentrarchus labrax L., 1758, with an emphasis on enumeration of heterotrophic bacteria in marine water. We applied two temperatures of incubation, as well as two methods for enumeration of heterotrophic bacteria: substrate SimPlate® test and spread plate method on conventional artificial media (Marine agar and Tryptic Soy agar with added NaCl. The results of analysis of bacteriological properties of marine water in the Adriatic fish farms showed that enumeration of heterotrophic bacteria in marine water depends on the applied incubation temperature and media for enumeration. At the same time, the incubation temperature of 22C favours more intense growth of marine heterotrophic bacteria, whereas a SimPlate test gives higher values of heterotrophic bacteria. Volatile values of heterotrophic bacteria during this research indicate a possible deterioration of microbiological water quality in the Adriatic fish farms and a need for regular monitoring of marine water quality.

    Full Text Available Ear infections occur in all age groups. Chronic Suppurative Otitis Media (CSOM is the most common illness in ENT practice. It may even cause hearing impairment especially sensory and ndash; neural deafness if not treated properly and with caution. The study was undertaken to know the aerobic microbiological/bacteriological profile of ear discharge and variations in sensitivity pattern to treat the patients efficiently. A total of 71 patients who had discharging ear infection were included in this study. The most common microorganisms isolated were Pseudomonas aeruginosa and Staphylococcus aureus followed by Coagulase-Negative Staphylococci (CoNS, Klebsiella spp, Proteus spp and Escherichia coli. Among the commonly used topical antibiotics, Ciprofloxacin appear to be first line antibiotic (91.52% sensitive to treat CSOM followed by Gentamycin (89.6% sensitive. However, the action of Chloramphenicol was low (59.53% sensitive. Ofloxacin can be used to treat CSOM due to Staphylococcus aureus other than Ciprofloxacin and Gentamycin.

    There is currently no established bacteriological beach quality monitoring (BQM) program in place in Malaysia. To initiate cost-effective, sustainable bacteriological BQM schemes for the ultimate goal of protecting public health, policy decision makers need to be provided robust, indigenous empirical findings that validate appropriate water quality parameters for inclusion in such monitoring programs. This is the first study that assesses the validity of enterococci as an ideal indicator for bacteriological BQM in Malaysia using a multivariate approach. Beach water and sand samples from 7 beach locations were analyzed for a total of twenty-one microbial and non-microbial water quality parameters. A multivariate approach incorporating cluster analyses (CA), principal component analyses (PCA), and factor analysis (FA) was also adopted. Apart from the weak correlations of Staphylococcus aureus with concentrations of Vibro species (r = 0.302, p = 0.037) and total coliforms (r = 0.392, p = 0.006) in seawater, no correlation existed between S. aureus concentration and other parameters. Faecal coliforms failed to correlate with any of the tested parameters. Enterococci also correlated with more quality parameters than faecal coliforms or any other indicator. Multiple linear regressions highlighted a significant, best fit model that could predict enterococci concentrations in relation to other parameters with a maximum predictive success of 69.64%. PCA/FA clearly delineated enterococci and faecal coliforms as parameters that weighed strongly for BQM while Staphylococcus aureus, faecal coliforms and enterococci weighed strongly for beach sand quality monitoring. On the whole, higher correlations of enterococci levels with other parameters than was observed for faecal coliforms suggest that the former be considered a preferred parameter of choice for BQM in Malaysia. Our findings provide meaningful evidence particularly as it relates to the correlation of

    Full Text Available Water from boreholes in Arib (Ain Defla, south-west of Algeria was investigated to ascertain its quality status and suitability for drinking and domestic uses. Fifty six water samples were collected from four boreholes. The analyses of the Coliform counts obtained from various boreholes samples ranged between 0 and 200 CFU/ 100 ml with regard to total Coliforms and between 0 and 8 CFU/ 100 ml with regard to fecal Coliforms. Three of the boreholes samples showed contamination by Streptococcus sp. Pathogens like Salmonella were not identified but some low levels of sulfite-reducing bacteria was found. The interviews were done to assess perceptions on water taste problems, odour, colour, and turbidity and health problems. The respondents were taken from people in the community using random sampling technique. Sixty people were sampled at each area surrounding the boreholes. It was found out that 43.3% of the respondents rated their drinking water safe for consumption as well as absence of illness after drinking as indicators for judging the quality of the water. The others respondents (56.7% reported having at least some concerns with safety of their water.  More  than 20% of the households reported at least one household member having suffered some water related illness in the past two years. Respondents were asked to judge the quality of the water, based on four sensory characteristics of drinking water. Many respondents rated the smell (33.3%, taste (20%, colour (23.3% and turbidity (23.3%. These results showed that all the samples did not satisfy the WHO requirements for bacteriological characteristics in human consumption.

    Full Text Available Background: Drinking water is a major source of microbial pathogens in developing regions although, poor sanitation and food sources are integral to enteric pathogen exposure. Poor water quality, sanitation and hygiene are responsible for the majority of deaths a year world-wide and mainly through infectious diarrhea. Objectives: The objectives of this study were to evaluate the bacteriological quality of drinking water at the source and point of use, to analyze the relationship between the presence of bacteria in water and diarrheic illness. Materials and Methods: A cross-sectional study was conducted on 100 water samples collected from various sources-bore wells, municipal tap waters, wells, and mineral water plants and also from storage containers in the house. Simultaneously, stool samples were also collected from households and processed. Results: Out of 100 water samples majority of them were consuming municipal water 16 (32%, followed by mineral water 14 (28%. For storage majority of them were using the candle filter 17 (34%, followed by steel containers 13 (26%. Escherichia coli was isolated in candle filters in the majority of cases 10 (29.4%, Enterobacter isolated in steel containers 6 (23%. Only in 50% diarrheal cases similar bacteria were observed both in water and stool samples. Conclusion: Water has become non-potable after storage due to various hygienic practices. Water may get contaminated at various levels, which is responsible for diarrheic illness. Safe water is essential for health. An efficient and well-maintained distribution system coupled with good hygienic practices would ensure that water is safe at the point of collection and before consumption.

    The aim of our study was to obtain comprehensive insight into the bacteriological and clinical profile of community-acquired pneumonia requiring hospitalization. The patient population consisted of 100 patients admitted with the diagnosis of community-acquired pneumonia (CAP), as defined by British Thoracic society, from December 1998 to Dec 2000, at the Sher- i-Kashmir institute of Medical Sciences Soura, Srinagar, India. Gram negative organisms were the commonest cause (19/29), followed by gram positive (10/29). In 71 cases no etiological cause was obtained. Pseudomonas aeruginosa was the commonest pathogen (10/29), followed by Staphylococcus aureus (7/29), Escherichia coli (6/29), Klebsiella spp. (3/29), Streptococcus pyogenes (1/29), Streptococcus pneumoniae (1/29) and Acinetobacter spp. (1/29). Sputum was the most common etiological source of organism isolation (26) followed by blood (6), pleural fluid (3), and pus culture (1). Maximum number of patients presented with cough (99%), fever (95%), tachycardia (92%), pleuritic chest pain (75%), sputum production (65%) and leucocytosis (43%). The commonest predisposing factors were smoking (65%), COPD (57%), structural lung disease (21%), diabetes mellitus (13%), and decreased level of consciousness following seizure (eight per cent) and chronic alcoholism (one per cent). Fourteen patients, of whom, nine were males and five females, died. Staphylococcus aureus was the causative organism in four, Pseudomonas in two, Klebsiella in one, and no organism was isolated in seven cases. The factors predicting mortality at admission were - age over 62 years, history of COPD or smoking, hypotension, altered sensorium, respiratory failure, leucocytosis, and staphylococcus pneumonia and undetermined etiology. The overall rate of identification of microbial etiology of community-acquired pneumonia was 29%, which is very low, and if serological tests for legionella, mycoplasma and viruses are performed the diagnostic yield would

    Pyodermas are a common group of infectious dermatological conditions on which few studies have been conducted. This study aimed to characterise the clinical and bacteriological profile of pyodermas, and to determine the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) infection in primary pyodermas in a dermatology outpatient department in Kashmir. Methods We conducted a hospital based cross-sectional study in the outpatient Department of Dermatology, Sexually Transmitted Diseases and Leprosy of Shri Maharaja Hari Singh Hospital, Srinagar, Jammu and Kashmir, India. Patients presenting with primary pyodermas were included in the study. A detailed history and complete physical and cutaneous examination was carried out along with microbiological testing to find aetiological microorganisms and their respectiveantimicrobial susceptibility patterns. Antimicrobial susceptibility testing, including that for methicillin resistance, was carried out by standard methods as outlined in the current Clinical and Laboratory Standards Institute guidelines. Results In total, 110 patients were included; the age of the study population ranged from 3 to 65 years (mean age 28 years); 62% were male. Poor personal hygiene was noted in 76 (69%). Furunculosis (56; 51%) was the most common clinical presentation. Staphylococcus aureus was isolated in 89 (81%) of cases, and MRSA formed 54/89 (61%) of Staphylococcus aureus isolates. All MRSA strains were sensitive to vancomycin. Conclusion The prevalence of MRSA was high in this sample of communityacquired primary pyodermas. It is therefore important to monitor the changing trends in bacterial infection and their antimicrobial susceptibility patterns and to formulate a definite antibiotic policy which may be helpful in decreasing the incidence of MRSA infection.

    Full Text Available Introduction: Urinary tract infection (UTI is a common cause of morbidity in patients attending our hospital. Recently UTI has become more complicated and difficult to treat because of appearance of pathogens with increasing resistance to the commonly used antimicrobial agents. Objectives: The main aim of the study was to determine the bacteriological profile and antibiotic susceptibility pattern of UTI patients attending our hospital. Materials and Methods: 1843 patients complaining of fever with or without urinary symptoms attending medicine and nephrology clinics of Jawaharlal Nehru Medical College Hospital, Aligarh from June 2012 to July 2014 were analysed. Clean catch mid-stream urine specimens collected from each subject were subjected to urine culture and sensitivity tests. Patients with age 15 to 85 years were included. Results: Significant bacteriuria was detected in 33.4% patients. Diabetes, obstructive uropathy, and previous instrumentation were the major risk factors identified. The most common pathogens isolated were Escherichia coli (52.4%, Klebsiella pneumoniae (12.3% and Citrobacter spp. (9.1%. Most susceptible antibiotic was Amikacin, Cefoperazone-sulbactum, Piperacillin-tazobactum and Nitrofurantoin for most of the isolates. E. coli which was the main isolate was found to be most susceptible to Amikacin (78.3%, Cefoperazone-sulbactum (72.8%, Piperacillin-tazobactum (70.5%, Gentamicin (69.3%, Nitrofurantoin (67.3%, Cefoperazone (64.1% and Ceftriaxone (61.6%. Conclusion: This study highlights the common pathogens causing UTI in our area and their antibiotic sensitivity patterns which could help clinicians in starting rational empirical antibiotic therapy for such patients while awaiting urine culture reports. This would significantly decrease the incidence of drug resistance and be more cost effective to the patients.

    The presence of metallo-β-lactamase (MBL)-producing and multidrug-resistant Pseudomonas aeruginosa (MDRP) strains among bovine isolates of Gram-negative bacilli, and O-serotypes of bovine Serratia marcescens and P. aeruginosa isolates have been reported rarely. The aims of this study were to (1) elucidate antimicrobial susceptibilities and O-serotypes of P. aeruginosa and S. marcescens isolates from bovine mastitis and the presence of MBL-producers and MDRP strains among them and (2) evaluate their relationships to human isolates. We investigated the MICs of 24 antimicrobials and O-serotypes for 116 P. aeruginosa and 55 S. marcescens isolates in Japan, primarily in 2006. A total of 171 isolates exhibited high antimicrobial susceptibilities with the exception of a partial drug. P. aeruginosa isolates exhibited high susceptibilities of ≥ 95.7% to ciprofloxacin, imipenem, meropenem, piperacillin, ceftazidime, cefepime, cefoperazone/sulbactam, amikacin, tobramycin, and gentamicin; however, they exhibited a susceptibility of only 69.8% to aztreonam. They exhibited substantial resistances to ceftriaxone, enrofloxacin, cefotaxime, and moxalactam. S. marcescens isolates exhibited high susceptibilities of ≥ 90.9% to kanamycin, ceftiofur, sulfamethoxazole-trimethoprim, and the 15 aforementioned drugs, but exhibited resistance to minocycline. Neither MBL-producers nor MDRP strains were detected among the 171 strains. The dominant serotypes of P. aeruginosa isolates were OG, OA, OB, OI, OF, OE, and OK; those of S. marcescens isolates were O6 and O5. Every S. marcescens isolate was pigmented. These findings suggest that bovine P. aeruginosa and S. marcescens isolates differ from human isolates from both antibiogram and phenotypic perspectives, and could help to evaluate differences in bacteriological characteristics between bovine and human isolates.

    The main objective of this work was to evaluate the microbiological quality of lettuces commercialized in the Metropolitan Area of San José, Costa Rica, and cultured in different ways, in order to detect differences between the culturing methods and the risk that these products may represent for Public Health. The study was done at the Food Microbiology Laboratory, Universidad de Costa Rica, from March to July, 2010. 30 lettuce samples were analyzed (10 obtained by traditional culture, 10 by organic culture and 10 by hydropony). All samples were obtained from markets where their origin was certified. Total aerobic plate count, total and fecal coliforms count and Escherichia coli were determined to all samples, as well as the presence/abscense of Salmonella spp. and Listeria monocytogenes in 25 g. Results obtained show that there is no statistically significant difference (p < 0.001) between the different types of cultures analyzed for any of the parameters evaluated. An important percentage of the samples presented coliforms, nevertheless, just one E. coli strain was isolated from a traditionally cultured lettuce sample. Four different Salmonella spp. strains were isolated from the samples as well as one Listeria monocytogenes strain. Data obtained show that the consumption of this product, raw or without an adequate hygiene and disinfection may represent a risk for health. Also, from the bacteriological point of view, there is no significant difference between the culturing methods evaluated, suggesting that the specific directions for each type of culture are not followed or that there is an inadequate handling of the products or post harvest contamination.

    Full Text Available The bacteriological quality of smoked game meat in Lubumbashi has not been studied much to date. The present study focused on the analysis of 182 samples of smoked game meat from three species, Syncerus caffer (n = 63, Phacochoerus aethiopicus (n = 60 and Sylvicapra grimmia (n = 59, sold at retail outlets in Lubumbashi. The isolation of Escherichia coli from 81.3% of samples (mean 4.87 ± 0.6 log10 CFU·g-1 of sample confirms significant faecal contamination of smoked game meat. The study has determined by culture prevalences of 0.0%, 4.3% [CI95% 1.4-7.4], 3.8% [CI95% 1.1-6.6] and 14.2% [CI95% 9.2-19.4] respectively for Shiga toxigenic Escherichia coli (STEC, Salmonella spp., Campylobacter jejuni and Campylobacter coli. Using Polymerase Chain Reaction, these prevalences were of 2.2% [IC95% 0.1-4.3], 6.0% [IC95% 2.6-9.5], 3.8% [IC95% 1.1-6.6] and 15.9% [IC95% 10.6-21.3] respectively for STEC, Salmonella spp., C. jejuni and C. coli. Syncerus caffer was established as a potential vehicle of STEC carrying stx1 gene (3.2%, stx2 gene (1.6% and the combination of stx2 and eae genes (1.6%. On the basis of these data, we suggested the need for developing monitoring plans of the production, preparation, handling and distribution of smoked game meat in Lubumbashi.

    Full Text Available BACKGROUND Pyogenic meningitis is one of the most common infectious disease emergencies involving the central nervous system with higher incidence in developing countries than developed nations. Despite the large number of pathogens that have been reported to cause acute pyogenic meningitis, certain microorganisms are isolated with higher frequency depending on patient’s age, immune status and geography. Present study was aimed to determine the trends in aetiology and spectrum of the bacteriological profile in adult patients with suspected pyogenic meningitis in North-East India. MATERIALS 50 CSF samples from as many patients of Acute Bacterial Meningitis over a period of one year were processed for cell counts, biochemical analysis, gram staining, culture, antigen detection by latex agglutination test and antibiotic susceptibility tests, as per standard techniques. OBSERVATION CSF cell counts showed neutrophilic predominance in all cases along with high protein and low sugar levels. 44% of the cases were culture positive and latex agglutination test was positive in 46.4% of the cases where culture was negative. S. pneumonia was the predominant pathogen identified in the present study in 12(24% cases, followed by Pseudomonas and E. coli in 5(10% cases each. Gram stain indicated the causative organisms in 68.2% of the culture positive cases. Among the culture negative patients gram stain indicated the causative organism in 3(10.7% cases and these three cases were positive by LAT also. CONCLUSION Simple, rapid, inexpensive tests like gram staining remain significant means for diagnosis of acute pyogenic meningitis in developing countries. LAT goes a long way in identifying the organisms where the cultures are negative. This study thus paves the way for larger studies in this region for better recognition of the predominant organisms and the empirical antibiotic regimens.

    Objective:To detect the various bacteriological agents and pathological changes in commercial layer chicken affected with egg yolk peritonitis in Namakkal region of India. Methods:A total of 6 572 layer chicken from 85 commercial farms were subjected for the study, out of which 1 715 showed various types of oviduct abnormalities. Among the 1 715, 264 birds from six farms were identified as egg peritonitis on the basis of postmortem examination. Trachea, lung, heart blood, liver, peritoneal exudate, oviduct (infundibulum, magnum, uterus) and cloacal swabs were collected from the 264 birds with egg peritonitis lesion for screening of bacterial agents. Signalment, clinical signs and pathological changes were recorded in the affected flocks. Result: The results of the present investigation indicated that the E. coli associated egg peritonitis was responsible for 15.39%of the reproductive tract abnormalities in commercial layers between 21 and 80 week of age. In the affected flocks egg production drop and mortality varied from 3%to 20%and 0.5%to 7.0%respectively. It was noticed during peak egg production (21 to 60 week) and southwest monsoon season (58%). Statistical analysis of age, season and egg production by Chi square test of independence revealed highly significant difference. E. coli was isolated as a pure culture and concurrent with other bacterial agents in 226 and 38 birds respectively. Among the fifteen E. coli serotypes identified serotype O166, O64 and O111 were predominant. Necropsy examination of affected birds revealed the presence of amorphous or insipissiated yolk material in the abdominal cavity with inflammatory changes in the ovary, oviduct and intestine. Microscopically the oviduct surface epithelium showed degeneration and desquamation, moderate to marked infiltration of inflammatory cells especially heterophils and lymphocytes in various regions and lumen contained serofibrinous exudate, inflammatory and desquamated epithelial cells with

    Full Text Available BACKGROUND: Middle ear infection is one of the most common condition in ENT practice, particularly in our country. Its significance lies in its chronicity and its dreaded complications like hearing loss and cholesteatoma. Chronic suppurative Otitis media and its complications are among the most common conditions seen by both the otologist and pediatrician. Both gram positive and negative organisms are responsible for infection of the middle ear. AIMS: The study was primarily carried out in 200 cases of C.S.O.M. to determine the bacteriological flora and to study the antibiotic sensitivity pattern of the organisms isolated on culture from discharging ears. RESULTS: In our study Pseudomonas aeruginosa was found to be the most common isolated bacteria (40.65% [100/246], followed by Staphylococcus aureus (14.63%[36/246], Klebsiella aerogenes (11.78%[29/246] and Proteus Mirabilis (10.56%[26/246]. Among the anerobic organisms Peptostreptococcus (5.69% was the most common followed by Propionibacterium (4.06% and Bacteroids spp. (3.65%. Amikacin was the most effective antibiotic in the present study. It was effective against maximum number of strains 97(95.48% followed by Gentamycin 95(92.36% and Ciprofloxacin 93(91.30%. Cefoperazone 88(86.42%, Cefotaxime 78(74.54% and Ofloxacin 64(62.68%. CONCLUSION: Efficient and effective treatment of CSOM is based on the knowledge of causative micro-organisms and thus their antimicrobial sensitivity ensures proper clinical recovery and avoidance of the possible dreaded complications. It has been observed that human negligence is one of the main factor responsible for the development of antibiotic resistance. Along with the indiscriminate use of antibiotics by the treating physician the lack of compliance on part of the patient also results in emergence of resistance and thus in treatment failure. It has been frequently encountered that as soon as the symptoms subside and improvement in condition occurs, many

Aims: The study was primarily carried out in 200 cases of C.S.O.M. to determine the bacteriological flora and to study the antibiotic sensitivity pattern of the organisms isolated on culture from discharging ears. Results: In our study Pseudomonas aeruginosa was found to be the most common isolated bacteria (40.65% [100/246], followed by Staphylococcus aureus (14.63% [36/246], Klebsiella aerogenes (11.78% [29/246] and Proteus Mirabilis (10.56% [26/246]. Among the anerobic organisms Peptostreptococcus (5.69% was the most common followed by Propionibacterium (4.06% and Bacteroids spp. (3.65%. Amikacin was the most effective antibiotic in the present study. It was effective against maximum number of strains 97 (95.48% followed by Gentamycin 95 (92.36% and Ciprofloxacin 93 (91.30%. Cefoperazone 88 (86.42%, Cefotaxime 78 (74.54% and Ofloxacin 64 (62.68%. Conclusion: Efficient and effective treatment of CSOM is based on the knowledge of causative micro-organisms and thus their antimicrobial sensitivity ensures proper clinical recovery and avoidance of the possible dreaded complications. It has been observed that human negligence is one of the main factor responsible for the development of antibiotic resistance. Along with the indiscriminate use of antibiotics by the treating physician the lack of compliance on part of the patient also results in emergence of resistance and thus in treatment failure. It has been frequently encountered that as soon as the symptoms subside and improvement in condition occurs

    Full Text Available The bacteriological quality of beef produced from most abattoir located in southern Nigeria has always been questionable. This work therefore investigated the bacteriological quality of abattoir facilities from both government and private owned abattoirs located in southern Nigeria. The results of our findings revealed that the total heterotrophic counts and total coliform counts exceeded the recommended standard for sanitary practices. Total heterotrophic counts from air flora ranged from 14.50 x 106to 42.50 x 106cfu. Beef-contact surface ranged from 26.50 x 106to 592.50 x 106cfu while total colony counts obtained from wastewaters from both government and private abattoirs ranged from 140.00 x 106to 1206.75 x 106cfu/ml. The total coliform counts also ranged from 14.25 x 103to 33.75 x 103for air flora and 76.00 x 103to 195.00 x 103cfu/ml for wastewaters. Eight bacterial isolates were consistently isolated during this study, and they included; Escherichia coli, Staphylococcus aureus, Staphylococcus sp., Citrobacter sp., Alcaligenes paradoxus, Klebsiella sp. and Enterococcus faecalis with varying percentage of frequency across the sampling points. The presence of indicator organisms as well as possible pathogens in this study is of special concern and stakeholders should be encouraged to review the processes involved in the establishment as well as operation of abattoir in southern Nigeria.

    Full Text Available This study was made to comprehend the effects of human behaviour on bacteriological quality of drinking water consumed by the population of Sô-Ava and to identify the possible environment factors that deteriorate the quality of water. Thirty samples of water were collected in different ways, during rainy season and dry season for bacteriological examination. To identify the environmental factors, 165 couples were questioned. The results recorded showed that during dry season the amounts of germs were within WHO safety limits for each and every sampling station while during rainy season the results highly exceeded the safety limits. The isolation of germs like total coliforms, faecal coliforms, Escherichia coli and Clostridium perfringens revealed a faecal pollution. The presence of pathogens like Staphylococcus, Salmonella and Shigella in surface water constituted a threat for the groundwater. The factors responsible for these contaminations were many and were mainly related to hygienic condition and sanitation according to the opinion poll. The improvement of health for the population of So-Ava implies-in addition to improving the quality of water, hygiene and sanitation and appropriate environment management of the town.

    A total of 956 quarter milk samples from 253 traditionally managed lactating camels were collected aseptically from Negele (Borena Region), Dire Dawa, and Gewane (Afar Region), Ethiopia, according to multi-stage sampling. The quarter milk samples were subjected to California Mastitis Test (CMT), Somatic Cell Counts (SCC) and bacteriological examinations. Five hundred and seventy one (59.7%) quarter milk samples had microorganisms. Of these, 428 (75.0%) had isolates that were identified as major pathogens (MAP) and 143 (25.0%) as minor pathogens (MIP). A positive correlation was found between CMT scores and bacteriological classes (MAP, MIP) (p-value = 0.00). Strong correlation (p-value = 0.00) between CMT scores and SCC was recorded. The differences among the median log SCC of bacteriological classes (MAP, MIP) were not significant (p-value = 0.24). Similarly, the application of the cut-off level of 2.5 x 10(5) ml(-1) indicated less agreement (p-value = 0.32) for bacteriological classes MAP and MIP. PMID:16450708

    Uterine microbiology, antimicrobial susceptibility and endometrial cytology were investigated in a total of 51 mares with fertility problems from 16 different stud farms in Serbia. Uterine cultures were performed after collection with a double guarded uterine swab, and endometrial cytology was evaluated after collection of endometrial cells with a special device (cytology brush). In 21 of 51 mares, at least one bacterial species was isolated from the uterus; the most frequent were Streptococcus equi subsp. zooepidemicus (13 isolates) and E. coli (four isolates). All isolates of Streptococcus equi subsp. zooepidemicus were susceptible to penicillin. Results from endometrial cytology were inconsistent; in 17 animals with positive bacteriological culture, cytology was not altered. It can be concluded that in Serbia, as in many other contries, Streptococcus equi subsp. zooepidemicus is the main cause for equine endometritis. It can be easily diagnosed by uterine culture but endometrial cytology does not always prove the existence of an endometrial infection with this agent. PMID:21038807

    Despite the increasing popularity of sprouted chia and flax seed powders, no data have been reported on their intrinsic physicochemical properties and background microflora. Here, we report the moisture content, water activity, pH, and fatty acid methyl ester and bacteriological profiles of 19 sprouted chia and flax seed samples, 10 of which were associated with an outbreak of salmonellosis in Canada and the United States. The physicochemical parameters of the Salmonella-positive samples did not differ significantly from those of the negative samples. However, the higher Enterobacteriaceae and coliform levels on the contaminated powders were associated with the presence of Salmonella. Enumeration of Salmonella by the most probable number (MPN) method revealed concentrations ranging from 1 MPN per 3 g of powder to 1 MPN per 556 g of powder. The results of this study demonstrate that low numbers of Salmonella may be linked to foodborne outbreaks. PMID:27296415

    The involution process of the postpartum bovine uterus is usually accompanied by invasion of various bacteria. The objectives of this study were to identify the relationship between the postpartum findings as risk factors for clinical endometritis (CE) and subclinical endometritis (SE). Furthermore, the effects of CE or SE on reproductive performance in small- and medium-sized dairy herds were investigated. A total of 400 cows were examined by vaginoscopy for CE at 20 to 30 days postpartum, and samples were collected for cytological examinations for SE and for bacteriology by cytobrush technique. The vaginoscopic and cytological examinations showed that 27.3% and 21.0% of the cows were found with CE and SE, respectively. The bacterial community analyses revealed a large variety of bacteria. Overall, bacteria from the order Actinomycetales, Lactobacillales, Bacillales, Burkholderiales, Caulobacteriales Enterobacteriales, Pasteurellales, and Pseudomonadales were detected, whereas in 39.5% of the samples no bacterial growth was detectable. The uterine pathogens Escherichia coli and Trueperella pyogenes were found in 16.8% and 13.0% of the samples cultivated under aerobic conditions. Other frequently isolated bacteria were Streptococcus spp. (31.3%), Staphylococcus spp. (20.0%), Corynebacterium spp. (16.5%), and Bacillus spp. (10.5%). The infection with T. pyogenes was the most important bacteriological risk factor for the occurrence of CE (odds ratio (OR) = 5.72; 95% CI = 3.07-10.83) and had a detrimental effect on the hazard of nonpregnancy by 200 days postpartum (hazard ratio = 1.66; 95% CI = 1.12-2.46). Calving assistance (OR = 1.79; 95% CI = 1.16-2.98) and farm (OR = 1.11; 95% CI = 1.02-1.20) were indicated as further risk factors for CE and SE. Effects of CE and SE on reproductive performance parameters could not be demonstrated. PMID:25066047

    The Australian Mycobacterium Reference Laboratory Network collects and analyses laboratory data on new cases of disease caused by the Mycobacterium tuberculosis complex. In 2007, a total of 872 cases were identified by bacteriology; an annual reporting rate of 4.1 cases per 100,000 population. Isolates were identified as M. tuberculosis (n=867), M. africanum (n=4) and M. bovis (n=1). Fifteen children aged under 10 years had bacteriologically-confirmed tuberculosis. Results of in vitro drug susceptibility testing were available for 871 of 872 isolates for isoniazid (H), rifampicin (R), ethambutol (E), and pyrazinamide (Z). A total of 98 (11.3%) isolates of M. tuberculosis were resistant to at least one of these anti-tuberculosis agents. Resistance to at least H and R (defined as multi-drug resistance, MDR) was detected in 24 (2.8%) isolates, all from overseas-born patients; 17 were from the respiratory tract (sputum n=16, endotracheal aspirate n=1). Thirteen patients with MDR-TB were from the Papua New Guinea-Torres Strait Islands zone. Of the 98 M. tuberculosis isolates resistant to at least one of the standard drugs, 54 (55.1%) were from new cases, 9 (9.2%) from previously treated cases, and no information was available on the remaining 35 cases. Seven were Australian-born, 90 were overseas- born, and the country of birth of 1 was unknown. Of the 90 overseas-born persons with drug resistant disease, 66 (73.3%) were from 5 countries: India (n=16); Papua New Guinea (n=15); the Philippines (n=12); Vietnam (n=12); and China (n=11). No XDR-TB was detected in 2007. PMID:20043600

    The influences of natural organic matter (NOM) and bacteriological characteristics on the biological stability of water were investigated in a full-scale drinking water treatment plant. We found that prechlorination decreased the hydrophobicity of the organic matter and significantly increased the high-molecular-weight (MW) dissolved organic matter, such as biopolymers and humic substances. High-MW organic matter and structurally complex compounds are known to be relatively slowly biodegradable; however, because of the prechlorination step, the indigenous bacteria could readily utilise these fractions as assimilable organic carbon. Sequential coagulation and sedimentation resulted in the substantial removal of biopolymer (74%), humic substance (33%), bacterial cells (79%), and assimilable organic carbon (67%). Rapid sand and granular activated carbon filtration induced an increase in the low-nucleic-acid content bacteria; however, these bacteria were biologically less active in relation to enzymatic activity and ATP. The granular activated carbon step was essential to securing biological stability (the ability to prevent bacterial growth) by removing the residual assimilable organic carbon that had formed during the ozone treatment. The growth potential of Escherichia coli and indigenous bacteria were found to differ in respect to NOM characteristics. In comparison with E. coli, the indigenous bacteria utilised a broader range of NOM as a carbon source. Principal component analysis demonstrated that the measured biological stability of water could differ, depending on the NOM characteristics, as well as on the bacterial inoculum selected for the analysis.

    A study was carried out to establish the prevalence of subclinical mastitis (SCM) in smallholder dairy farms in Ismailia, Egypt. A total of 340 milking cows and buffaloes were sampled from 60 farms, and 50 nasal swabs were collected from consenting farm workers. Milk samples were subjected to California mastitis test (CMT) and the positive samples were examined by bacterial culture and PCR to identify etiological agents. Based on CMT, the prevalence of SCM was 71.6 % in cattle and 43.5 % in buffaloes while the prevalence was 25.2 % at cow-quarter level and 21.7 % at buffaloes-quarter level. Bacteriological analysis showed that the most frequently identified bacteria were Staphylococcus (S.) aureus (38.3 %) and Streptococcus (Str.) agalactiae (20 %). The diagnostic sensitivity of PCR compared to bacterial culture was superior with S. aureus and Str. agalactiae detection being 41 and 22.6 %, respectively. Furthermore, methicillin-resistant S. aureus (MRSA) strains occurred in 52.2 and 45 % of isolates of animals and workers, respectively. Subclinical mastitis due to S. aureus and Str. agalactiae is endemic in smallholder dairy herds in Ismailia. The occurrence of MRSA in animals and workers highlights a need for wide epidemiological studies of MRSA and adopting control strategies. PMID:25374070

  4. Experience with a pilot plant for the irradiation of sewage sludge: Bacteriological and parasitological studies after irradiation

    International Nuclear Information System (INIS)

    Comparative bacteriological studies of sewage sludge in a sewage plant have demonstrated that mechanical-biological sewage treatment reduced the total bacterial count and those of Enterococces by 2 log and the Enterobacteriaceae by 3-4 log. Frequently Salmonella could be isolated from sewage sludge. A further reduction of viable micro-organisms could be achieved by irradiation of sewage sludge (60Co, gamma-radiation, 260 krad, 210 min). This reduction amounted to an average of 2 log with Enterococces and total bacterial count, and to 5 log with Enterobacteriaceae. Out of 40 samples investigated after irradiation, two contained Salmonella. The hygienic effects of the irradiation unit were demonstrated by means of a model experiment with bacterial pure cultures. Micro-organisms of different species as well as strains of the same species differ in their sensitivity to irradiation. Parasitological experiments with eggs of Ascaris suum were carried out to test the inhibitory or killing ability of the gamma rays on the developing stages of parasites

    No gold standard assay exhibiting error-free classification of results has been identified for detection of Renibacterium salmoninarum, the causative agent of salmonid bacterial kidney disease. Validation of diagnostic assays for R. salmoninarum has been hindered by its unique characteristics and biology, and difficulties in locating suitable populations of reference test animals. Infection status of fish in test populations is often unknown, and it is commonly assumed that the assay yielding the most positive results has the highest diagnostic accuracy, without consideration of misclassification of results. In this research, quantification of R. salmoninarum in samples by bacteriological culture provided a standardized measure of viable bacteria to evaluate analytical performance characteristics (sensitivity, specificity and repeatability) of non-culture assays in three matrices (phosphate-buffered saline, ovarian fluid and kidney tissue). Non-culture assays included polyclonal enzyme-linked immunosorbent assay (ELISA), direct smear fluorescent antibody technique (FAT), membrane-filtration FAT, nested polymerase chain reaction (nested PCR) and three real-time quantitative PCR assays. Injection challenge of specific pathogen-free Chinook salmon, Oncorhynchus tshawytscha (Walbaum), with R. salmoninarum was used to estimate diagnostic sensitivity and specificity. Results did not identify a single assay demonstrating the highest analytical and diagnostic performance characteristics, but revealed strengths and weaknesses of each test. PMID:23346868

    Full Text Available Abstract Bacteriological and nutritional analysis of groundnut cake powder sold in open market at Samaru-Zaria was studied. The samples collected from four zones of the study area were analysed for possible microbiological contamination and its nutritional quality. The results indicated a microbial load of 1.93 x 105 cfug and 1.94 x 105 cfug for zones A and B respectively 1.01 x 105 cfug for zone C and 2.37 x 105 cfug for zone D. The bacterial isolates found to be associated with the groundnut cake powder in this study included Klebsiella oxytoca Staphylococcus aureus Bacillus cereus E. coli P. aeruginosa and Streptococcus feacalis. The nutrients content of the sample included carbohydrates 55.15 moisture 12.65 lipid 15.40 protein 12.60 ash 3.95 and crude fibre 0.25. Groundnut cake sold in the study area is highly contaminated with bacteria except for samples from zone C which is within the Food and Drugs Agency FDA recommendation of 1.0 x 105cfuml as allowable microbial contamination for food. The high level of microbial contamination is a serious cause for concern as it may trigger epidemics. However the product is highly nutritious.

    This review analyzes some of the main events during the twentieth century that led to the birth of virology. In the literature of the time, a relationship of causality was established between virus and disease, and within this pathological context, the notions of fixed virus, volatile virus, contagium vivum fluidum and contagium fixum were formed. The transformation of the virus concept as a technoscientific object took place based on the criterion of filterability and on the methodology devised for the bacteriology dogma. Studies on tobacco mosaic virus are highlighted, as well as those on viral diseases of human beings and animals, which led to the discovery of these submicroscopic agents through the appropriation of technologies and the impulse triggered by political and economic factors.

    Full Text Available Background: There is not much published literature on neonatal septicemia available for the Sub-Himalayan region of North India. Hence, we undertook this study to find out the bacteriological profile and antibiotic sensitivity pattern of neonatal septicemia in the neonatal Intensive Care Unit. Material and Methods: Blood cultures were performed for all clinically suspected neonatal septicemia cases for 1-year. Identification of all pathogenic isolates was followed by antibiotic sensitivity testing. Results: We did blood cultures for 450 neonates and 42% were culture positive. Early onset sepsis were 92 (49% and 96 (51% were late onset sepsis. Gram-positive isolates were 60% and 40% were Gram-negative. Staphylococcus aureus (40%, coagulase negative Staphylococcus species (16%, non-fermenter group of organisms (NFGOs (15%, and Klebsiella pneumoniae (10% were the main isolates. Nasal cannula 101 (54%, birth asphyxia 91 (48%, and prematurity 73 (38% were the prominent risk factors associated with septicemia. Gram-positive organisms were highly resistant to penicillin (87% whereas Gram-negative isolates showed high resistance to third generation cephalosporins (53–89% and aminoglycosides (50–67%. The S. aureus isolates were methicillin-resistant in 41% whereas extended spectrum beta lactamase production was seen in 48% Gram-negative isolates.Conclusion: Our study highlights the recent emergence of Gram-positive organisms as predominant cause of neonatal septicemia in this part of Sub-Himalayan region, along with the review of literature which shows similar results from North India and rest of the world too. Though Gram-negative bacteria still remain the main cause of mortality in neonatal septicemia, we want to dispel the common notion among practitioners that they are the predominant isolates in neonatal septicemia.

    Full Text Available Acute exacerbations are significant and frequent events in the natural history of chronic obstructive pulmonary disease. Majority of these exacerbations are of infectious aetiology, bacteria being responsible for 30-50% of these cases. With not many studies of similar type being conducted in the Indian context, this study was undertaken with the purpose of determining the bacteriology of acute exacerbations of chronic obstructive pulmonary disease in hospitalized patients with advanced disease and their antibiotic susceptibility pattern to formulate a cost effective algorithm for antibiotic usage while at the same time reducing the chances of emergence of drug resistance. Sputum sample from a total of 338 patients were send for Gram’s stain and culture sensitivity testing using an array of the commonly used antibiotics. Pathogenic bacteria were isolated from 203 (60.1% samples. Gram negative bacteria were isolated from 79.8 percent (162/203 cases while the rest were Gram positive. Klebsiella species were the commonest (49.2%; 100/203 Gram negative isolates from the sputum samples. Among the gram negative organisms, Carbapenem had the highest sensitivity (90.2% followed by Amikacin, Ciprofloxacin and Piperacillin-Tazobactam. Linezolid was found to be 100 percent sensitive amongst the Gram positive organisms while both Amoxicillin Clavulanate and Azithromycin showed a rather low sensitivity profile overall. 5.0 percent of the Klebsiella infections were multi drug resistant. It was thereby concluded that either Amikacin, Ciprofloxacin or Piperacillin-Tazobactam for be considered for Gram negative organisms and Linezolid be considered for Gram positive organisms as first line antibiotics in empirical therapy while Carbapenems may be kept as reserve drugs should the first line drugs fail.

    The study was carried out to determine the bacteriological safety of water in hand-dug wells in the Atebubu-Amantin District of the Brong-Ahafo Region in Ghana. A total of 60 samples were collected from ten hand dug wells and analysed for total coliform (TC), faecal coliform (FC), E. coli (EC), Salmonella spp. (SP) and Enterococcus spp. (ES). Data was collected in both the rainy and the dry seasons. The results obtained showed that water from all the wells in the study area did not meet the World Health Organisation guideline and Ghana standard for drinking water of zero (0) coliform forming unit (cfu) per 100 ml for TC, FC, EC, SP and ES, respectively. Contamination was found to be high in the wells during the wet season as compared to the dry season. Wells (A1 to A5) which were close to septic tanks had high bacteria counts in both seasons. The total coliform counts ranged from 2.98 to 5.93 log cfu/100 ml in the wet season and 3.10-5.03 log cfu/100 ml in the dry season. There was drastic reduction of faecal coliform count from a range of 2.78-4.55 log cfu/100 ml in the wet season to 1.70-3.51 log cfu/100 ml in the dry season. The high bacteria count in wells A1 to A5 could be attributed to the closeness of the wells to the septic tank, and contaminant transport through the saturated underground zones. It is recommended that the water should be treated properly before drinking.

  11. Physico-chemical and bacteriological quality of water from shallow wells in two rural communities in Benue state, Nigeria

    International Nuclear Information System (INIS)

    Ground water abstraction from shallow wells is widely practiced in the Obi and in Oju rural areas of Benue State, Central Nigeria, as a means of fighting guinea worm infestation associated with the surface water sources (streams) in these areas. To ascertain the physico-chemical and bacteriological quality of the water used by the population, water samples from 27 shallow wells in Obi and 19 Oju were taken and examined for key health -related quality parameters using routine methods. In Obi, the ground water colour ranged from 4.0-80.0 TCU, conductivity 55.2- 1600.0 ILS/cm, pH 6.1-8.6, TDS 38.6-1286 mg/L, turbidity 1.0 - 55.0 NTU, arsenic 0.001- 0.210 mg/L, copper 0.01-2.53 mg/L, fluoride 0.08-1.82 mg/L and nitrate 10.8-63.0 mg/L; while in Oju, colour varied from 2.0-87.0 TCU, conductivity 1 07.4-1375 LS/cmp, H 6.4-8.53, TDS 75.2- 1150 mg/L, turbidity 3.0-48.0 NTU, arsenic 0.001-0.023 mg/L, copper 0.01-2.10 mg/L, fluoride 0.01-1.54 mg/L and nitrate 10.2-59.7 mg/L. Some of these values in some instances exceed the WHO standard for drinking water. Alongside with the presence significant total coliform count in most of the wells (0-47/100 mL in Oju and 0-53/100 mL in Obi), the available water is considered largely unsafe for human consumption as obtained.

    Full Text Available Background: Chronic dacryocystitis is an inflammation of the lacrimal sac which usually occurs because of the obstruction of the nasolacrimal duct. Objective: The primary objective of the study was to know its clinico-bacteriological profile. Materials and Methods: This prospective observational study was carried out over a period of one year to know the current bacterial flora involved in chronic dacryocystitis. All specimens were processed for isolation and identification of bacterial pathogens according to the standard microbiological techniques. The antibiotic susceptibility pattern was done by Kirby-Bauer disc diffusion method according to the Clinical Laboratory Standards Institute guidelines. Results: Among total 100 cases of chronic dacryocystitis, the highest percentage of infections in relation to age was noted in the age group of 50-60 years and the prevalence rate was higher in female patients compared with male. Out of total chronic dacryocystitis cases, 72% cases were found to be culture positive. Among positive culture, gram positive organisms were higher than that of Gram-negative. Staphylococcus epidermidis was the most frequently isolated and Streptococcus pyogenes was least isolated. The highest percentage of positive samples was found in the mucopurulent discharge followed by extensive purulent and clear fluid, respectively. In Gram-positive isolates, chloramphenicol was the most sensitive followed by cefazolin, ciprofloxacin, ofloxacin, cephalexin, vancomycin, gentamycin, and tobramycin, respectively, whereas in Gram-negative isolate, chloramphenicol and nalidixic acid were equally effective followed by ofloxacin, gentamycin, cephalexin, cefazolin and ciprofloxacin, respectively. Conclusion: S. epidermidis was the most frequently isolated bacteria, and chloramphenicol was the most susceptible drug in Gram-positive and Gram-negative bacteria.

    Full Text Available Microorganisms remaining in dentin following cavity preparation may induce pulp damage, requiring the use of pulp-capping agents with antimicrobial activity underneath permanent restorations. OBJECTIVE: The aims of this study were to analyze the bacteriological status of carious dentin and to assess the efficacy of different base underneath silver amalgam restorations. MATERIAL AND METHODS: This study was conducted on 50 patients aged 13 to 30 years. Sterile swabs were used to take samples after cavity preparation, which was assessed by microbiological culture to identify the microorganisms present. Following this, cavities were restored with silver amalgam, using one of the materials being investigated, as the base: calcium hydroxide (Group II, polyantibiotic paste (Group III, a novel light-cured fluoride-releasing hydroxyapatite-based liner (Group IV and mineral trioxide aggregate - MTA (Group V. In Group I, the cavities were restored with silver amalgam, without any base. After 3 months, the amalgam was removed and samples taken again and analyzed for the microbial flora. RESULTS: Lactobacilli were the most commonly isolated microorganisms in the samples of carious dentin. Groups IV and V showed negative culture in the 3-month samples. There was no statistically significant difference between Groups I, II and III. There was no significant difference between Groups IV and V (p>0.05. Both Groups IV and V showed significantly better results when compared to Groups I, II and III (p<0.05. CONCLUSIONS: The hydroxyapatite-based liner and MTA performed significantly better in terms of antibacterial activity than the other materials.

    Full Text Available Background: Otitis media with effusion is one of the leading causes of hearing loss in children. Effective treatment of effusion in the middle ear requires appropriate empirical treatment and characterization of responsible pathogens. Objective of the present study was to detect pathogens in clinical samples from patients with otitis media with effusion in our area and to determine the sensitivity profile of isolated organisms to commonly used antibiotics. Methods: Sixty three samples of middle ear effusion were aseptically obtained from 36 children, who had been treated up to at least two weeks before sampling. They were analyzed using standard bacteriological and multiplex polymerase chain reaction (PCR assays. Antibiotic susceptibility tests were also performed. Results: PCR analysis showed that DNA of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis were present in 60 (95.2% of the samples. The culture-positive effusion for Streptococcus Pneumoniae, HaemophilusInfluenzae and Moraxella catarrhalis was 34.9%. Almost all isolates of Streptococcus pneumoniaee were sensitive to ciprofloxacin and erythromycin, and none of them was sensitive to co-trimoxazole. None of H. Influenzae isolates was sensitive to erythromycin, cefixim, co-trimoxazole, ampicillin and amoxicillin. None of M. Catarrhalis isolates was sensitive to ceftriaxone, co-trimoxazole, ampicillin and amoxicillin. Conclusion: Compared with other studies using PCR method, the number of H. influenza isolates was in higher in the present study (95.2%. Antibiotic sensitivity profiles of pathogens isolated in this study were different from others. Thus, we can determine empirical antibiotic therapy based on sensi-tivity profile in our geographic area.

    Bacteriology of Panipuri was studied and the antibacterial effect of eight essential oils (EOs) was established on pathogens found in Panipuri. Samples were collected from twelve respective vendors from different locations in Baripada city, Orissa. Samples were fractionated into two parts viz. khatta pani and smashed potato masala used in Panipuri. Total plate count and isolation of pathogenic bacteria were done on both basal and selective media. Coliforms were detected primarily by presumptive test and confirmed subsequently, using Eosine Methylene Blue Agar. Selected colonies were pure cultured and identified through staining and an array of biochemical reactions. Antibiogram pattern of the pathogens and their susceptibility towards eight different EOs were performed. Antibacterial efficacy of four EOs in food sample was studied. Aerobic bacterial load of solid samples was observed to be more than in the liquid samples. Coliform-positive samples were found to be of 80.33%. Pathogenic bacteria like Escherichia coli, Klebsiella sp., Enterobactor sp., Bacillus sp., Enterococcus sp., Micrococcus tetragens, Salmonella paratyphi, Shigella dysenteriae and Vibrio sp. were detected. Antibiogram studies of the isolates showed multiple antibiotic resistance index (MRI;%) ranging from 15 to 92%. Among the EOs studied Cinnamon and Clove oils showed maximum antibacterial activity. Antibacterial efficacy showed that Clove and Cinnamon oils were comparatively of superior quality than Turmeric leaf and Japanese mint oils to kill food borne pathogens. Although it was a preliminary endeavor, the present study is a prerequisite in understanding the significance of pathogenic microorganisms in street foods and use of EOs as both antibacterial agents and food preservatives.

    Full Text Available BACKGROUND The study was aimed at finding out the bacteriology of the tonsillar surface and core, in those patients undergoing tonsillectomy at a tertiary care hospital. The study was also planned to look for the antibiotic resistance pattern among organisms identified and to see whether a tonsillar surface swab can be used as a surrogate for finding out the aetiopathogenesis of tonsillar infections. METHODS This is a 2-year cross-sectional study of 100 patients undergoing who consented for the study, after taking a smear from the surface of the tonsil. Tonsillectomy was done by dissection and snare method. The core of the tonsil is then biopsied and microbiological culture and sensitivity is done. The bacteria were identified by morphology and staining characteristics and cultured using standard laboratory procedures. Antimicrobial susceptibility was done by Kirby-Bauer disc diffusion method. The data was digitalised using a data entry platform using Epidata and analysed using SPSS 16. Relativity between organism identified as the surface and core was tested using Chi-square tests and Kappa statistics. RESULTS There were significant differences between the organisms identified from the tonsillar surface and the core; out of the 200 specimens, only 48 showed a similar bacteriology. The viability between the surface and the core specimens were measured using Kappa statistics and was found to be 0.04, which shows a very poor agreement between them. Assessment of antibiotic sensitivity shows that Staph aureus was resistant to most of the commonly used antibiotics. H. influenza isolated showed 70% susceptibility to erythromycin and cotrimoxazole. While group A β haemolytic streptococci showed 95% susceptibility to ampicillin and 100% to erythromycin. CONCLUSION Staph. aureus, H. influenza, Streptococci pneumonia were the major pathogenesis identified from the tonsil of the patients undergoing tonsillectomy, and bacteriology was different between

    Full Text Available Abstract Background In many parts of the world, health problems and diseases have often been caused by discharging untreated or inadequately treated wastewater. In this study, we aimed to control physico-chemical parameters in wastewater samples. Also, microbiological analyses were done to reveal Salmonella strains and each Escherichia coli (E.coli pathotype. Findings Sixty wastewater samples were collected from fifteen different regions of Tunisia. All physico-chemical parameters (pH, residual free chlorine, total suspended solids, biological oxygen demand, and chemical oxygen demand were evaluated. For microbiological analyses, samples were filtered to concentrate bacteria. DNA was extracted by boiling and subjected to polymerase chain reaction (PCR using different pairs of primers. The mean pH values recorded for the sampling point were above the WHO pH tolerance limit. The total suspended solids (TSS concentrations varied between 240 mg/L and 733 mg/L in entrance points and between 13 mg/L and 76 mg/L in exit points. In entrance points, the studied wastewater has an average COD concentration that varied between 795 mg/mL to 1420 mg/mL. Whereas, BOD concentration of the wastewater ranged between 270 mg/L to 610 mg/L. In exit points, COD concentration varied between 59 mg/L and 141 mg/L, whereas BOD concentration ranged from 15 mg/L to 87 mg/L. The bacteriological control of wastewaters showed that, in entrance points, Escherichia coli (E.coli was detected at the rate of 76.6%. Three E.coli pathotypes were found: ETEC (53.3%, EAEC (16.6% and EIEC (6.6%. Concerning the ETEC isolated strains, 8 of 16 (50% have only the heat-labile toxin gene, 5 of 16 (31.2% present only the heat-stable toxin gene and 3 of 16 (18.7% of strains possess both heat-labile toxin gene and heat-stable toxin gene. In exist point, the same pathotypes were found but all detected ETEC strains present only the "est" gene. Concerning Salmonella isolated strains; percentages

    Mastitis, inflammation of the mammary gland, is an important cause of disease, mortality, and production losses in dairy and meat sheep. Mastitis is commonly caused by intramammary infection with bacteria, which can be detected by bacterial culture or PCR. PathoProof (Thermo Fisher Scientific Ltd., Vantaa, Finland) is a commercially available real-time PCR system for the detection of bovine mastitis pathogens. Sheep differ from cattle in the bacterial species or bacterial strains that cause mastitis, as well as in the composition of their milk. The aim of this study was to evaluate whether the PathoProof system was suitable for detection of mastitis pathogens in sheep milk. Milk samples were collected aseptically from 219 udder halves of 113 clinically healthy ewes in a single flock. Aliquots were used for bacteriological culture and real-time PCR-based detection of bacteria. For species identified by culture, the diagnosis was confirmed by species-specific conventional PCR or by sequencing of a housekeeping gene. The majority of samples were negative by culture (74.4% of 219 samples) and real-time PCR (82.3% of 192 samples). Agreement was observed for 138 of 192 samples. Thirty-four samples were positive by culture only, mostly due to presence of species that are not covered by primers in the PCR system (e.g., Mannheimia spp.). Two samples were positive for Streptococcus uberis by culture but not by PCR directly from the milk samples. This was not due to inability of the PCR primers to amplify ovine Streptococcus uberis, as diluted DNA extracts from the same samples and DNA extracts from the bacterial isolates were positive by real-time PCR. For samples containing Staphylococcus spp., 11 samples were positive by culture and PCR, 9 by culture only, and 20 by PCR only. Samples that were negative by either method had lower bacterial load than samples that were positive for both methods, whereas no clear relation with species identity was observed. This study provides

    Full Text Available Ground water abstraction from shallow wells is widely practiced in the Obi and in Oju rural areas of Benue State, Central Nigeria, as a means of fighting guinea worm infestation associated with the surface water sources (streams in these areas. To ascertain the physico-chemical and bacteriological quality of the water used by the population, water samples from 27 shallow wells in Obi and 19 Oju were taken and examined for key health-related quality parameters using routine methods. In Obi, the ground water colour ranged from 4.0-80.0 TCU, conductivity 55.2-1600.0 µS/cm, pH 6.1-8.6, TDS 38.6-1286 mg/L, turbidity 1.0-55.0 NTU, arsenic 0.001-0.210mg/L, copper 0.01-2.53mg/L, fluoride 0.08-1.82mg/L and nitrate 10.8-63.0mg/L, while in Oju, colour varied from 2.0-87.0 TCU, conductivity 107.4-1375 µS/cm, pH 6.4-8.53, TDS 75.2-1150 mg/L, turbidity 3.0-48.0 NTU, arsenic 0.001-0.023 mg/L, copper 0.01-2.10 mg/L, fluoride 0.01-1.54 mg/L and nitrate 10.2-59.7 mg/L. Some of these values in some instances exceed the WHO standard for drinking water. Alongside with the presence significant total coliform count in most of the wells (0-47/100 mL in Oju and 0-53/100 mL in Obi, the available water is considered largely unsafe for human consumption as obtained. It is concluded that, while ground water abstraction may be a safety measure against guinea worm infestation it, nevertheless presents other health challenges to the rural population in the area, as the quality of the ground water is generally low.

    The author discusses the evolution in the classification of the bacterium, responsible for plague: first a classification based on phenotypic characteristics, later based on genotypic characteristics, to finally arrive at an evolutionist classification. He treats the seven species of the genus Yersinia that can be distinguished by DNA hybridization. He examines the issue of sequencing and decoding the chromosome and mentions research regarding the phenomenon that the metabolism of the organisms modifies as a reaction to signals of their changing environment. Furthermore the author discusses the efforts to characterize the strains of Y. pestis (antiqua, medievalis and orientalis). Finally he comments on the discovery of a multiresistant strain, isolated in 1995 in Madagascar. PMID:10379199

    At the end of the nineteenth century provincial bacteriological institutes were established in Belgium--in Liège, Mons, Namur and Brussels--in order to combat epidemics, to promote preventive medicine and to pursue the successful research of Louis Pasteur and Robert Koch. Similar laboratories existed at the universities of Ghent, Louvain and Brussels. The image building played an important role for both kinds of institutes, as bacteriology in pioneering phase had to be publicly confirmed as a new, valuable discipline. However, the directors of provincial and academic institutes--with the same academic training though--were awarded with different qualities at their jubilees, fitting with the purposes and the self-image of their respective institutions, either provincial authorities or universities. The image of academic directors was guided by academic decorum: Emile van Ermengem, Edmond Destrée and Joseph Denys were represented as savants, solely devoted to pure science and paternally educating young researchers, notwithstanding the fact that their laboratories had humanitarian merits as well. On the other hand, the discourse on the first provincial directors--Ernest Malvoz, Martin Herman, Achille Haibe--emphasized their altruistic commitment and their solid work for the provincial government. Jules Bordet, a internationally rewarded scientist, professor and provincial director of the Pasteur Institute in Brussels, was celebrated with both sorts of discourses. PMID:22586760

    Full Text Available To determine factors influencing the utilization and accessibility to bacteriologic-based tuberculosis (TB diagnosis among sputum smear positive (SS+ retreatment TB patients, and to develop strategies for improving the case detection rate of MDR-TB in rural China.A cross-sectional study of SS+ TB retreatment patients was conducted in eight counties from three provinces with different implementation period and strategy of MDR-TB program in China. Demographic and socioeconomic parameters were collected by self-reporting questionnaires. Sputum samples were collected and cultured by the laboratory of county-designated TB clinics and delivered to prefectural Centers for Disease Prevention and Control (CDC labs for DST with 4 first-line anti-TB drugs.Among the 196 SS+ retreatment patients, 61.22% received culture tests during current treatment. Patients from more developed regions (OR = 24.0 and 3.6, 95% CI: 8.6-67.3 and 1.1-11.6, with better socio-economic status (OR = 3. 8, 95% CI: 1.3-10.7, who had multiple previous anti-TB treatments (OR = 5.0, 95% CI: 1.6-15.9, and who failed in the most recent anti-TB treatment (OR = 2.6, 95% CI: 1.0-6.4 were more likely to receive culture tests. The percentage of isolates resistant to any of first-line anti-TB drugs and MDR-TB were 50.0% (95% CI: 39.8%-60.2% and 30.4% (95% CI: 21.0%-39.8% respectively.Retreatment SS+ TB patients, high risk MDR-TB population, had poor utilization of access to bacteriologic-based TB diagnosis, which is far from optimal. The next step of anti-TB strategy should be focused on how to make bacteriological-based diagnosis cheaper, safer and more maneuverable, and how to assure the DST-guided treatment for these high-risk TB patients.

    The authors give the results of their cytological and bacteriological examinations of the cervix and vagina carried out routinely in a laboratory. They emphasize, in detailing their method of working, the criteria that they feel must be adopted in an attempt to code the qualitative appraisal of direct examination and the result of studying the cultures. The first part of the paper deals with an overall survey of the 4,573 examinations which were carried out over a period of 8 years. The second part is concerned with a more detailed analysis of the 883 samples which were divided into 4 categories: pregnant women, those having oral contraception, those with an intra-uterine device, and others. There are several variations revealed between these 4 categories as far as the white cell count, the bacterial flora and even pathogenic organisms are concerned. PMID:7334191

    Full Text Available Background: This study was conducted to compare the efficacy of enzyme-linked immunosorbent assay (ELISA for detecting anti-Helicobacter pylori (H. pylori specific IgG antibodies in specimens of oral fluid and serum with bacteriological tests. Methods: Antral biopsy specimens, as well as serum and oral fluid samples were collected from 97 patients who underwent upper gastrointestinal endoscopy. The presence or absence of current H. pylori infection was determined by culture, histology and urease detection. Anti-H. pylori specific IgG was detected in serum and oral fluid, using an established lab-made, and a commercial ELISA kit. The obtained data were compared with results of bacteriological tests. Results: In all, 62 (64% of 97 patients were positive for H. pylori by one or more of the gold standard tests (culture, histology and urease detection. Lab-made enzyme-linked immunoassay of oral fluid had a sensitivity and specificity of 92% and 83% respectively. A sensitivity and specificity of 87% and 83%, respectively, was obtained with the commercial kit. Lab-made enzyme-linked immunoassay of serum samples had a sensitivity and specificity of 90% and 88%, respectively. A sensitivity of 86% and specificity of 86% was obtained with the commercial kit. Conclusion: Detection of anti-H. pylori specific IgG in oral fluid by ELISA is comparable in sensitivity and specificity with serum based methods. Oral fluid based ELISA could provide a reliable, non-invasive method for the diagnosis of H. pylori infection. Saliva testing may have a role in epidemiological studies.

The first, two and fifth types are well known and recognized by specialists; the fourth group has been recognized by Beck & Eber, in 1920; the third group was recognized by ourselves, in 1935. b The table found in this paper summarizes the most important characteristics of these five types. The changes produced on neutral red, H²S production, fermentation of glycerol, isodulcitol, xylose, dulcite, sorbitol and maltose, the activity upon Seignette salt, gas production and appearance of the colonies, are among the characteristics on which the distinction of these five types is founded. c The gasogenic gallinarum type, on account of its action on sorbitol and xylose, and also on Jordan's medium, must be rather considered as a gasogenic intermedius type. d Other biological characteristics, such as activity upon milk, milk-whey, dextrin, etc., accepted by several specialists, appeared as of no practical value to the distinction of the different types of our strains. e The strains kept their properties invariable during all the time of our investigations. The hypothesis of a possible transformation of one type into another has not been confirmed in any of the studied strains and this justifies the idea of independence of each one of the accepted types. f Some discrepances in fermentation of maltose as found by several authors in microorganisms of this group, have been not confirmed in this paper. g In

    Full Text Available Background: Leprosy has been a major public-health problem in many developing countries for centuries. According to the National Leprosy Elimination Programme report of March 2012, there were a total of about 0.13 million cases of leprosy in India, 9.7% of which were children. Numerous studies have investigated child leprosy amongst reported cases however, studies pertaining to proportion and characteristics of undetected childhood cases in the community are very few. Aim: To examine the clinical, bacteriological, and histopathological characteristics of newly detected child leprosy cases in the community. Methods: The population survey conducted from June to September 2007 and the defined rural areas, which included five primary health centers of Panvel Taluka, in Raigad district and urban areas, which included M-east ward of the municipal corporation of greater Mumbai of western Maharashtra, India. Results: House-to-house survey yielded 32 and 37 so far, undetected child cases of leprosy in the rural and urban region, and the prevalence rate was 10.5 and 1.5 per 10,000, respectively. The age of child leprosy cases detected, ranged from 3 to 14 years with a mean of 10.06 ± 3.35 years in the rural and 9.97 ± 3.12 years in the urban area. Most of the cases were paucibacillary (62%. A large proportion of children (49% had single skin lesion (SSL. Of the 19 SSL cases examined histopathologically, 15 (99% showed features of borderline tuberculoid, 1 (5% borderline lepromatous and 3 (16% had indeterminate type of leprosy. Tuberculoid leprosy was not seen in any, indicating less likelihood of self-healing. Overall, three cases had deformity (grade 1 = 1 and grade 2 = 2 and 31% of multibacillary cases were smear positive. Conclusion: The clinical, bacteriological, and histopathological characteristics of newly detected child cases in the community evidently indicate the grave nature of the problem of undetected child leprosy, recent active

    Objective:To investigate the relationship between antibiotic administration and the changes in bacteriological profile in a burn unit. Methods: The data of consumption of different kinds of antibiotics, including total antibiotic consumption [expressed as the number of defined daily doses (DDD)] as well as pathogen identification, were collected in a 8-year period. The constituent ratios of different kinds of antibiotics in total antibiotic consumption to isolation rates of various species of bacteria were calculated, and their correlation was analyzed. Results: Within this period, it was found that the aminoglycosides and first generation cephalosporins were used less frequently, while the polypeptides, carbopenem and macrolides were used proportionally more. At the same time, the isolation rates of Staphylococcus aureus, Acinetobacter sp, Enterobacter cloacae, Klebsiella pneumoniae and methicillin-resistant Staphylococcus aureus were gradually increased. The constituent ratios of predominant pathogens were correlated to the different kinds of antibiotics consumption in the burn unit. Conclusion: The results suggested that the consumption of different antibiotics was closely related to the trends of emergence of bacterial isolates from infected burn wounds. The result might imply that to regulate the administration of certain antibiotics might help decrease the emergence of certain pathogenic bacteria in burn infections.

    Full Text Available This work aimed to assess the bacteriological quality of water used in the irrigation of vegetable gardens in the municipalities of Araraquara, Boa Esperança do Sul and Ibitinga, São Paulo, Brazil. A total of 80 samples of water used in the irrigation of 40 vegetable gardens were analyzed, two samples coming from each vegetable garden. They were collected at the same site in different months, which resulted in two sample collection groups. The most probable number (MPN/100mL of total coliforms, thermotolerant coliforms and enterococci was identifi ed by means of the multiple tube technique. The analysis of the fi rst group samples showed quantities of thermotolerant coliforms above the amount allowed by current law for irrigation water (CONAMA Resolution n. 357 in nine cases. The owners of those vegetable gardens were then instructed in water disinfection procedures. After the analysis of the second group samples, it was noticed that only one sample did not meet the quality standards, and it was collected at a site where no disinfection procedure had been carried out. According to the results, 77.5% of the vegetable gardens were using water whose samples meet the quality standards. After the owners were instructed with regard to disinfection procedures, that number changed to 97.5%, which confi rms the importance of controlling and supervising irrigation water quality.

    From 2011 to 2013, we conducted a full sanitary survey of pollution sources in proximity to a shellfish growing area in the Hansan-Geojeman region in Korea, which includes a designated shellfish growing area. In the sea area, 1152 seawater and 209 oyster samples were collected and examined to evaluate their bacteriological quality. There were 758 potential pollution sources in the drainage area, including 40 sources discharging water in 2013. Fecal coliform (FC) concentrations and impact radii of discharges ranged from 1.8 to 700,000 MPN/100 mL and from 3 to 600 m, respectively; however, the pollutants did not reach the designated area. This demonstrates that the dilution of waste was sufficient such that no significant impact occurred within the designated shellfish growing area. The variation in the FC levels of seawater was closely related to season and rainfall. The FC levels of seawater and oysters from the designated area met the regulation limits set by various countries. No pathogens were found in any oysters. The results of the survey indicate that the oysters produced in this area are apparently safe for raw consumption based on their bacterial quality. PMID:27610330

    Full Text Available AbAns etxrpaecritment was carried out with 630 one-day-old chicks to evaluate the effects of organic acids when birds were experimentally inoculated with Salmonella Typhimurium. Liver damage and the persistence of the bacterium in the organs were evaluated as well. Broilers were distributed in a completely randomised experimental design in a 3×2 factorial arrangement of six treatments with seven replicates of 15 birds each. Birds were inoculated with saline solution or the bacterium via gavage at 1 day of age, or were offered a feed containing or not the organic acid blend for the period of 7 to 14 days of age. A dose of 5.0x102 colony-forming units (CFU/0.5 mL of Salmonella Typhimurium was used for inoculation both via gavage and feed. The parameters evaluated are weight, liver histopathology, liver and serum biochemistry, and bacteriological analyses of the caeca, crop, spleen, and liver and heart pool. At 21 and 28 days of age, the liver of the non-inoculated groups was significantly lighter as compared to the other treatments. Birds fed organic acids presented lower bacterial isolation rates in all organs tested. Birds inoculated in the crop and treated with organic acids presented lower E. coli CFU counts (P<0.05. Birds inoculated with Salmonella presented significant changes (P<0.05 in liver enzymes, as detected by serum biochemistry, and in liver histopathology. It was concluded that organic acids effectively controlled Salmonella Typhimurium and did not cause any liver damage.

    Objective: To assess normal conjunctival cytological and bacteriological/fungal flora features in the Mediterranean buffalo(Bubalus bubalis).Methods: Swabs were taken from the inferior conjunctival sac of both eyes of 57 healthy female buffaloes aged 24–36 months, with no evidence of ocular disease, farmed in Campania region(Southern Italy), for microbiological analysis. Conjunctival eye specimens of both eyes were subsequently obtained by a cyto-brush, for cytological analysis.The antimicrobial susceptibility of bacterial isolates was also determined using the diskdiffusion method on Mueller Hinton agar plates.Results: Cytological examination of conjunctival swab specimens(114 eyes) revealed epithelial cells(basal, intermediate, columnar and super ficial) in all samples, whereas neutrophils, lymphocytes and plasma cells were present in 70%, 10% and 2% of samples,respectively. Microorganisms, for a total of 261 aerobic bacteria and 6 fungi, were isolated from 112/114 conjunctival samples [98.25%; 95% con fidence interval(CI): 93.18–99.70]. Only two conjunctival swabs did not yield bacteria and/or fungi(2/114, 1.75%;95% CI: 0.30–6.82). Gram-positive aerobes were most commonly cultured(181/261,69.35%; 95% CI: 63.31–74.81), with Enterococcus faecium and Staphylococcus lentus predominating. Escherichia coli was the most frequently isolated as Gram-negative bacteria(80/261, 30.65%; 95% CI: 25.19–36.69). The antimicrobial resistance patterns of the isolated bacteria showed amoxycillin/clavulanic acid and cephalothin as the least sensitive antibiotics for both Gram-positive and Gram-negative bacteria.Conclusions: These results provided first information on normal conjunctival ocular micro flora and cytological features in Mediterranean buffalo.

  15. Correlations among the somatic cell count of individual bulk milk, result of the California Mastitis Test and bacteriological status of the udder in dairy cows.

    2004-01-01

    In a survey of about 3000 dairy cows producing low somatic cell count (SCC) milk and kept on a large-scale dairy farm, California Mastitis Test (CMT) positivity was found in 2714 udder quarters of 1491 cows. Pathogenic microorganisms were isolated from 57.6% of these 2714 udder quarters during bacteriological examination. The commonest pathogens were coagulase-negative staphylococci (CNS, 41%) and Staphylococcus aureus (32.5%); however, udder infections caused by environmental streptococci (12.8%) and coliform bacteria (6.8%) were also common. All pathogens resulted in a significant increase of the SCC in individual bulk milk (IBM) samples. In the case of CNS, this SCC elevation in IBM was significantly lower than in the case of infection by the other pathogens. In spite of this, because of the high number of udder infections caused by CNS, the adverse effect exerted by CNS on dairy herds is considered to be substantial. It was found that 54.6% of all CMT-positive cows produced IBM of an SCC below 400 thousand per ml. The milk produced by 41% of the 315 cows excreting S. aureus also had an SCC below 400 thousand per ml. This poses a serious risk of infection to the healthy herdmates. At the same time, 11% of the infected cows produced IBM with an SCC below 100 thousand per ml. On the basis of these findings, only the regular analysis of SCC of IBM can be a reliable indicator of chronic intramammary infection. As the SCC of milk produced by CMT-positive cows (and especially of those excreting pathogens) tended to increase with advancing lactation, the authors suggest that an efficient drying-off therapy should be used to restore udder health and, whenever justified, culling of cows cannot be avoided either.

    Introduction Acute calculous (obstructive) cholecystitis develops as a consequence of cystic obstruction and obstruction of bile flow into choledochus. Most often it is a result of impacted gallstones in Hartman's pouch or the cystic duct. Their direct pressure on gallbladder mucosa causes ischemia, necrosis and ulceration with consequential wall edema and obstructed venous flow. This mechanism is further increasing and spreading the inflammatory process. Ulcerations may be that extensive, th...

Burn injury is a major public health problem in many areas of the world. Burns predispose to infection by damaging the protective barrier function of the skin, thus facilitating the entry of pa thogenic microorganisms and by inducing systemic immunosuppression . (1 OBJECTIVE : The present study was therefore undertaken to isolate and identify the aerobic bacterial flora in burn patients and its antibiotic susceptibility pattern. MATERIAL & METHODS : A total of 100 patients admitted with different degree of burns were studied. Wound swabs were taken with aseptic precautions by dry sterile cotton swab sticks. These swabs were transported to the microbiology laboratory and the isolates were identified based on standard microbiological methods. Antibiotic susceptibility testing was done by Kirby Bauer’s disc diffusion method. RESULT : A total of 127 bacterial pathogens were isolated from 100 patients. Of these, 69% were monomicrobial in nature and 28% wer e polymicrobial. The most frequent cause of infection was found to be Staphylococcus aureus (39.4%, followed by Pseudomonas aeruginosa (14.2%, Klebsiella pneumonia (13.4%, E.coli (8.7% and Acinetobacter species (7.9%.Out of the total Staphylococcus au reus isolates, 19 were Methicillin sensitive and 31 were Methicillin resistant (MRSA. All the MRSA strains were 100% sensitive to Vancomycin and Linezolid. The Pseudomonas aeruginosa isolates were most sensitive to Amikacin (9 4.4%, Fluroquinolones (61.1% . CONCLUSION : Staphylococcus aureus and Pseudomonas aeruginosa were major causes of infection in burn wounds. Therefore it is necessary to implement urgent measures for restriction of nosocomial infections, sensible limitation on the use of antimicrobial agents, strict disinfection and hygiene.

  6. Determination of the physico-chemical and bacteriological quality of water from hand dug wells in the Ga-West Municipality, Accra, Ghana

    International Nuclear Information System (INIS)

    The Ga-West Municipality is noted for high reported cases of Buruli Ulcer and other water-borne diseases. A large section of the population of the municipality depends on boreholes and hand-dug wells to meet their basic daily water requirement. The hand-dug wells and boreholes, unlike treated piped water and Water Kiosk Programmes in the communities of the study area are not frequently monitored for their bacteriological, physic-chemical parameters and trace elements content; to ascertain their suitability for drinking and other important domestic chores. The study assessed the quality (bacteriological, physico-chemical and trace elements) of water from hand-dug wells and boreholes in communities within the Ga West Municipality. Groundwater samples were collected in November and December 2014 from hand-dug wells and boreholes in twenty-three (19) communities within the Ga-West Municipality for the study. pH, Total Dissolved Solids, Electric Conductivity and Temperature were determined onsite with the portable Multifunctional HACH-Conductivity meter. HCO3- Alkalinity, Calcium and Total Hardness were determined by Titrimetry. Trace metals (Mn, Fe, Co, Ni, Cu, Pb, Cd, Zn) and Mg were determined by Atomic Absorption Spectrometry. For bacterial indicators, Aerobic Colony Count Technique was employed. Fecal Coliform and E-coli were determined using Violet Red Bile-salt Agar Media, and Indole Test used to confirm Ecoli. Plate Count Agar Media was used in the determination of Total Coliform. pH was acidic to weakly alkaline (4.5 - 8.5) for hand-dug wells and weakly acidic to near-neutral (6.4 - 7.5) in the boreholes. Total Dissolved Solids were generally high with about 35.7 % of the samples exceeding WHO recommended Guideline of 1000 mg/L in both hand-dug wells and boreholes. According to TDS classification by Freeze and Cherry, 74.3 % of the groundwater samples were classified as fresh, (TDS ‹100 mg/L) and 35.7 % as brackish (TDS › 100 mg/L). Total Hardness values

    There is a need for more sensitive detection methods to improve effectiveness of control programmes of Salmonella enterica subsp. enterica serotypes (Salmonella) in cattle. We assessed the performance of a rapid, molecular-based, real-time PCR (rt-PCR) method against the conventional bacteriological culture-reference method (BCRM) on cattle faecal samples for detection of sub-clinical Salmonella infections in cattle. Thirty faecal samples were artificially contaminated with either 10 or 50 CFU of one of five strains of S. Dublin (SD) and S. Typhimurium (ST). The overall detection sensitivity of both rt-PCR and BCRM was 100% for ST and 78% for SD. Furthermore, 163 faecal samples from cattle herds with suspected Salmonella infection were tested to compare the relative performance of rt-PCR to BCRM on samples from naturally infected herds. The relative sensitivity of rt-PCR was 20% (3/15 BCRM positive samples) while the relative specificity and accuracy was 99% and 92%, respectively. Both methods had limitations for detecting low levels of SD (Salmonella-infectious cattle. PMID:23391438

    For a natural pond, whose waters are used for recreational purposes (swimming) and are subject to waste water inflow, the biological purifying function of a zone overgrown with reeds and aquatic plants was ascertained by means of chemical and bacteriological water quality parameters. In the years from 1975 to 1980 the contents of ammonia, nitrites, nitrates, phosphates and chlorides as well as the colony counts (CFU/ml), the coli titres and the content of fruiting myxobacteria were determined from water samples, both during the lush-growth summer period and the low-growth winter season. The location of the 6 sampling points systematically extended from the sewage outlet via the tributary ditch, in front of and behind the natural growth zone as far as the swimming waters. The test series showed - that in the tributary ditch and especially during the passage through the upper water zone densely overgrown with aquatic plants, the proportion of degradable nitrogen compounds and phosphates is distinctly reduced beyond the extent of reduction by dilution processes, - that the colony counts in the effluent water as well as the content of E. coli and of the fruiting myxobacteria, which act as indirect faecal indicator, are also reduced considerably, - that the biological purifying of the vegetation zone is definitely higher in summer than during the low-growth winter months. From this the conclusion can be drawn that for maintaining and furthering an adequate water quality of recreational waters compromised by waste water, the preservation of the naturally growing aquatic plants both in the water itself and on the banks is absolutely necessary.

    Full Text Available Neonatal septicemia remains a significant cause of morbidity and mortality in the new born, more so in developing countries like India due to delivery and post natal follow up in an unclean environment having more chances of contamination with infective organisms. Infection is more common in the neonatal period than at any other time in life . 1 This is partly attributable to exposure to large number of organisms, but is also due to a relative failure of the neonatal host defenses to clear microorganisms from blood and tissues. The rate of infection and type of organism causing sepsis in a neonate vary with demography. In India, the incidence of neonatal septicemia is 10 - 30/1000 live births , 2 whereas in western countries it is 1 - 8/1000 live births . 3 KEYWORDS: Neonatal, Sepsis, Staphylococcus, CRP, Bandemia

    The cellular morphology, identifying physiological characteristics, and a key to the human genera of Micrococcaceae are presented with flow charts for identification of aerobic and anaerobic isolates. These flow charts can be amended as desired, depending upon the degree of accuracy desired. Micrococcaceae isolates in a 350-bed private general hospital during a 15-week period are tabulated to show relative numbers of the different genera and species, with their probable relationship to infection or contamination. Only 11 of the 220 Micrococcaceae isolates were not Staphylococcus; no Sarcina or Peptococcus were isolated. Of the Staphylococcus isolates, 61% were S. epidermidis. Almost 18% of the S. aureus isolates were coagulase-negative. Of the S. aureus isolates, 80% of the coagulase-positive isolates were infecting agents, as were 67% of the coagulase-negative S. aureus isolates, compared to only 48% of S. epidermidis isolates. Two of four Gaffkya isolates but only one of seven Micrococcus isolates were infecting agents. If coagulase production is used as the sole criterion for speciation of staphylococci, and Micrococcus is not differentiated from Staphylococcus, the term "coagulase-negative staphylococci" does not differentiate three distinct levels of pathogenicity. Coagulase-negative S. aureus is more virulent than S. epidermidis or Gaffkya, which are more virulent than Micrococcus or Sarcina. PMID:4874454

    The main factors predisposing the onset of the carious process are: 1 the presence of bacterial species able to lower the pH until critical values of 5.5, 2 the absence of adequate oral hygiene, 3 an inefficient immune response anti-caries, 4 the type of alimentary diet and 5 the structure of the teeth. Among the 200 bacterial species isolated from dental plaque the most pathogenic for dental caries are: Streptococcus mutans, Streptococcus sobrinus, Lactobacillus acidophilus, Actinomices viscusus and Bifidobacterium dentium. Our laboratory (LAB® s.r.l., Codigoro, Ferrara, Italy has developed a test for absolute and relative quantification of the most common oral cariogenic bacteria. The test uses specific primers and probes for the amplification of bacteria genome sequences in Polymerase Chain Reaction Real Time. The results provide a profile of patient infection, helpful for improving the diagnosis and planning of preventive treatment to reduce the bacterial load.

    Full Text Available This study concentrates on information concerning the microbiological hazards that can be present in raw milk from animal species other than cows. A total of 54 (23 of ovine and 31 of goat bulk tank milk samples from 10 farms in the Czech Republic were collected in years 2013 - 2014. The sampling was done at regular time intervals during the whole year, with five to eight samples collected from each of the 10 dairy farms involved in the study. All milk samples were collected into sterile sampling bottles and transported in a cooler sampling case to the laboratory for immediate examination. Farms were randomly selected to cover the whole area of the Czech Republic. The prevalence and characteristic of Escherichia coli, Staphylococcus aureus, Salmonella spp., Campylobacter spp. and Listeria monocytogenes was studied. Raw cow's milk can be contaminated by E. coli intramammarily during clinical or subclinical mastitis and either directly through animal feces or indirectly during milk collection through farm employees or the milking equipment. E. coli was detected in 90.3% of the goat milk and 95.7% of the ovine milk samples. The genes encoding Shiga toxins 1 and 2- (stx1, stx2 were not detected and no STEC was identified. The Eae was the detected in 3 (4.6% isolates. S. aureus was detected in 9 (29.0% samples of goat milk and 8 (34.8% samples of ovine milk.

    Full Text Available Abstract Background Clinical mastitis is an important disease in sheep. The objective of this work was to identify causal bacteria and study certain epidemiological and clinical features of clinical mastitis in ewes kept for meat and wool production. Methods The study included 509 ewes with clinical mastitis from 353 flocks located in 14 of the 19 counties in Norway. Clinical examination and collection of udder secretions were carried out by veterinarians. Pulsed-field gel electrophoresis (PFGE was performed on 92 Staphylococcus aureus isolates from 64 ewes. Results and conclusion S. aureus was recovered from 65.3% of 547 clinically affected mammary glands, coagulase-negative staphylococci from 2.9%, enterobacteria, mainly Escherichia coli, from 7.3%, Streptococcus spp. from 4.6%, Mannheimia haemolytica from 1.8% and various other bacteria from 4.9%, while no bacteria were cultured from 13.2% of the samples. Forty percent of the ewes with unilateral clinical S. aureus mastitis also had a subclinical S. aureus infection in the other mammary gland. Twenty-four of 28 (86% pairs of S. aureus isolates obtained from clinically and subclinically affected mammary glands of the same ewe were indistinguishable by PFGE. The number of identical pairs was significantly greater than expected, based on the distribution of different S. aureus types within the flocks. One-third of the cases occurred during the first week after lambing, while a second peak was observed in the third week of lactation. Gangrene was present in 8.8% of the clinically affected glands; S. aureus was recovered from 72.9%, Clostridium perfringens from 6.3% and E. coli from 6.3% of the secretions from such glands. This study shows that S. aureus predominates as a cause of clinical ovine mastitis in Norway, also in very severe cases. Results also indicate that S. aureus is frequently spread between udder halves of infected ewes.

    Full Text Available Peritonitis is defined as inflammation of peritoneum that lines the abdominal cavity and the organs contained therein. In Surgical practice we most often encounter cases of peritonitis which are mostly secondary to hollow viscous perforation. Purpose of our study is to find out which type of peritonitis is more common in our institute, which is the most common bacteria isolated from peritoneal fluid and which antibiotic is it most sensitive to. We studied 104 cases o f age group 16 and above of both sex who presented with clinical features of peritonitis. Peritoneal fluid was obtained and sent for culture and sensitivity. Peritoneal fluid culture was positive in 55.76% cases. The incidence of culture positivity increas ed with duration of presentation. Gastro duodenal perforation was the most common etiological factor for peritonitis found in 42.86% cases followed by ileal perforation. E. c oli was the most common bacteria isolated in study group followed by klebsiella. M ost of the cultures were monomicrbial. E. coli was sensitive to amikacin, imipenem and meropenem (100%. So in our study Gram negative infection is more common in surgical peritonitis. Identification of bacteria and its sensitivity to the antibiotics is he lpful to avoid injudicious use of antibiotics in surgical peritonitis. Proper choice of antibiotics along with surgical management and proper resuscitation in cases of surgical peritonitis can reduces mortality and morbidity associated with these high risk cases

    Asbestos cement (AC) pipes were commonly installed in the drinking water distribution systems from the mid 1920s to the late 1980s. In recent years, an increase in the number of water main breaks has occurred in the AC portions of some pipe networks, which can be partially attributed to the corrosion of the aged pipes. This study evaluated the potential role that microorganisms may have played in the degeneration and failure of AC pipes. In this study, a fresh AC pipe section was collected from the distribution network of the City of Regina, Canada and examined for microbiological activities and growth on inside surfaces of pipe sample. Black slime bacterial growths were found to be attached to inner pipe surfaces and a distinctively fibrous internal coating (patina) with iron oxides was formed over the time. The microbial populations inside the patina and the black slime were tested with BART testers. Heterotrophic aerobic bacteria (HAB) and slime forming bacteria (SLYM) dominated in both the black growths and inside the patina. Iron related bacteria, denitrification bacteria and sulfate reducing bacteria were also commonly present. Microbial challenge assays were conducted by submerging the cut segments of the AC pipe into selected bacterial cultures for a period of 10 days under both aerobic and anaerobic environments. Weight changes were determined and the surface morphology was examined for each of the assayed pipe segments. Results indicated that acid producing bacteria, SLYM and HAB could facilitate the pipe weight loss under anaerobicenvironments. PMID:21179959

    Full Text Available This study highlights the problem of soil pollution as the result of human activities. Soil pollutans may be either chemicals or biological in nature. microbial enzymatic activities are often proposed as indicators of environmental stress. The soil samples were submitted by chemical, microbiological and enzymatic analyses. Chemical analyses were been made for determinating the heavy metals. Heavy metals from the forest soil were represented by Cu, Zn, Mn, Ni, Pb, Cd and Cr. To evaluate the concentration in heavy metals from the filtrate, we used a acetylene-nitrous oxide flame atomic absorption spectrophotometry. Potential dehydrogenase activity, the only indicator of the possible sources of pollution, excluded the presence of either chemical or biological pollution. The number of bacteria involved in the biogeochemical cycle of nitrogen in the analyzed soil indicated a high efficiency regarding the mineralization of the organic residues of plant and animal origin.

  7. [Bacteriological diagnosis of tuberculosis: current hieratic classification of methods].

    1995-01-01

    To assure the diagnosis of tuberculosis, one needs the observation, the isolation and the identification of the causative agent Mycobacterium tuberculosis. In this approach, the microscopic exam occurs as a fast but neither sensitive or specific test. The isolation on solid media is slow and needs more than three weeks before becoming positive. Nevertheless, it is a sensitive and specific one. The identification of the isolated strain and the study of sensitivity to antibiotic agents require an equal delay. Then, 2 months are necessary to achieve the analysis. The AIDS epidemic with the increase of opportunistic mycobacterial diseases, and the unexpected arrival of resistant Mycobacteria is creating as a difficult therapeutic problem. The cultivation in liquid media with the radiometric method (Bactec) shortens the time of culture by half. The genomic amplification assay has been hopeful because it allowed results in 2 days. However, some technical difficulties happen when the test is conducted and it is less sensitive than the isolation process. The hierarchical classification of the laboratory useful process to establish the diagnosis of tuberculosis disease remains the microscopic observation of the bacilli and their isolation. Today, the use of PCR alone does not assure the diagnosis of tuberculosis, however it may be used as a additional diagnostic test. PMID:7569420

    Full Text Available Background: Aim of current study was to estimate the prevalence of Bacterial Vaginosis (BV among women with Unexplained Infertility (UI and to describe laparoscopic appearances in positive cases. Methods: Design: Prospective randomized comparative diagnostic trial. Setting: Tertiary care referral facility and University hospital. Patients: One hundred and fifty women divided into UI study group A (120 cases and a control group B (30 cases. Intervention(s: Vaginal and endouterine swabs form two subgroups of the UI group (60 cases each and vaginal swabs from control group (30 cases. All swabs were tested using Amsels criteria then cultured. Thereafter, UI group (60 cases was subjected to diagnostic laparoscopy. Main outcome measure(s: the prevalence of BV among women with UI and laparoscopic findings among positive cases. Results: In the study group, the number of positive cases of BV confirmed by culture was 51 cases (42.5% while it was diagnosed in three cases (10% in group B (P = 0.0001. In group A, BV was diagnosed in 24 and 27 infertile cases with periods of infertility less than and more than 3 years respectively and in 39 patients (32.5% with recurrent vaginitis without statistically significant difference. There was an insignificant difference in diagnosis of BV whether the site of sample was the posterior fornix of the vagina or the endometrial cavity. Positive laparoscopic findings were reported in 77 patients (64.2%. The most common laparoscopic abnormalities were hyperemic uterus and chronic salpingitis. Conclusions: BV is frequently implicated in female infertility and it is probably an underestimated cause of UI. There is no extra benefit from using culture instead of Amsel's criteria for the diagnosis of BV. No difference in the site of sample taking in diagnosis of BV from posterior vaginal fornix or endometrial cavity. Laparoscopy is very beneficial in explaining the effect of BV on the upper genital tract. [Int J Reprod Contracept Obstet Gynecol 2015; 4(1.000: 173-178

    Full Text Available The often-high mortality and morbidity rates of surgical site infections are the concern of most health practitioners including administrators globally. The need to know the bacterial agents responsible and their treatability to common antibiotics was the main thrust of this study. Two hundred surgical site swabs were collected from two hospitals and investigated. The swabs were cultured and organisms identified according to standard procedures. A prevalence rate of 31.5% was obtained from the surgical sites investigated. Direct gram staining gave a greater recovery rate of incriminated organisms than cultural methods. Staphylococcus aureus was the most encountered pathogen with 13.0% prevalence rate followed by Pseudomonas aeruginosa (6.5%, Proteus mirabilis (6.0% and Klebsiella aerogenes (4.0%.The least encountered pathogens were Beta-haemolytic streptococci and Escherichia coli with prevalence rates of 1.0% each. Statistically, chi square analysis showed that there was no significant difference in the number of isolates from the two health facilities at 99% confidence limit. Susceptibility of isolates was more with the aminoglycosides than with the penicillins. This study has thus revealed that some hospitals are not doing enough to stem the tide of surgical site infections.

  19. Bacteriological (fecal and total coliform) quality of Pakistani coastal water

    International Nuclear Information System (INIS)

    The coliform bacteria group consists of several genera of bacteria belonging to the family enterobacteriaceae. These are harmless bacteria, mostly live in soil, water, and digestive system of animals. Fecal coliform bacteria, which belongs to this group, are present in large numbers in feces and intestinal tract of human beings and other warm-blooded animals which can enter into water bodies from human and animal waste. Swimming in water having high levels of Fecal coliform bacteria increases the chance of developing illness (fever, nausea or stomach cramps) from pathogens entering the body through mouth, nose, ears or cuts in the skin. The objective of the present study was to characterize the bathing quality of Pakistani coastal water with respect to coliform bacteria. Total and Fecal coliform bacteria were determined at seven different locations along Pakistan coast using membrane filtration (MF) technique. 100 ml of water was passed through 0.45 micron (mu) filter paper. These filter papers were put on pads, soaked in Lauryle sulphate broth in petri-dishes and incubated at 44 deg. C for Fecal and 37 deg. for Total coliform for 24 hours. Significantly high population of Fecal and Total coliform bacteria was recorded at Karachi harbour area and Indus delta region. Results indicate that a large amount of domestically originated waste is being discharged into these locations without any pre-treatment (e.g., screening, activated sludge, by using filtration beds etc.) resulting in a poor seawater quality making it unfit for bathing.

    Full Text Available The evaluation of the quality of the water used for irrigation in agriculture is of great importance for the environmentand human health. The continuous use of contaminated water causes pollution to soil and cultivated crops, causing variousdiseases associated with consumption of contaminated vegetables. Thus, the objective of this study was to evaluate the qualityof irrigation water of three water bodies: artesian wells, cacimbas (kind of graves that collect water from swampy lands andstreams, used in the Nova Esperança Agricultural Community, located between a peripheral urban area and a native forestin Manaus - AM. Potentially toxic metals (PTM: Cd, Cu, Co, Fe, Ni, Mn and Zn were evaluated using atomic absorptionspectrometry by flame and bacteriological analyses (total and faecal coliforms by filter membrane method. The results showedhigh levels of total and faecal coliforms, 89,3% in water samples collected in the three water bodies, as well as high levels of TPM, especially Cd and Pb extremely toxic. Statistical tests showed the influence of the seasonal period on the average concentrations of the PTM and there is not meaning difference of these contaminants on the different water bodies during the period of this study. = A avaliação da qualidade da água utilizada para a irrigação no meio agrícola é relevante tanto para o meio ambiente, quanto para a saúde humana.

    Full Text Available Aim: To study which organisms were prevalent in our burn unit and their antibiotic sensitivity pattern in brief. Method: Microbiological data of 1534 patients admitted to the burns unit of the Bai Jerbai Wadia Hospital for Children, Mumbai over a period of 13 years (1994-2006 was reviewed retrospectively. A total of 9333 swabs were cultured and antibiotic sensitivities to the isolated organisms determined. The age group of patients admitted to our facility ranged from one month to 15 years. Result: Klebsiella was the predominant organism in our set-up (33.91%, closely followed by Pseudomonas (31.84%. The antibiotic sensitivities of the isolated organisms are discussed in detail in the text. Conclusion: Every treatment facility has microorganisms unique to it and these change with time. It is therefore of paramount importance to have an in-depth knowledge of the resident organisms and their antibiotic sensitivity pattern so that infection-related morbidity and mortality are improved.

  2. Escherichia coli as an indicator of bacteriological quality of water: an overview

    Full Text Available Monitoring the microbiological quality of drinking water relies largely on examination of indicator bacteria such as coliforms, Escherichia coli, and Pseudomonas aeruginosa. E. coli is a member of the faecal coliform group and is a more specific indicator of faecal pollution than other faecal coliforms. Two key factors have led to the trend toward the use of E. coli as the preferred indicator for the detection of faecal contamination, not only in drinking water, but also in other matrices as well: first, the finding that some faecal coliforms were non faecal in origin, and second, the development of improved testing methods for E. coli. The faecal coliform definition has also been revised to coincide better with the genetic make-up of its members and now includes newly identified environmental species. As a result, faecal coliforms are increasingly being referred to as thermotolerant coliforms. This, combined with improved detection methods for E. coli, has started a trend toward the use of E. coli in place of thermotolerant coliforms as a more reliable indicator of faecal pollution in drinking water. At present, E. coli appears to provide the best bacterial indication of faecal contamination in drinking water. This is based on the prevalence of thermotolerant (faecal coliforms in temperate environments as compared to the rare incidence of E. coli, the prevalence of E. coli in human and animal faeces as compared to other thermotolerant coliforms, and the availability of affordable, fast, sensitive, specific and easier to perform detection methods for E. coli.

    In most cases the diagnosis of any molar dental disease in horses is made at an advanced stage, so that permanent restoration of the diseased teeth is not feasible. Complications such as bacteraemia and septicaemia due to infections as a result of dentogenous sinusitis and following dentosurgical procedures have been described in human medicine and in veterinary medicine. Twenty patients were available for examination from the Clinic for Horses of the School of Veterinary Medicine Hannover with molar dental disease in upper or lower jaw. As a result of this disease the infected tooth had to be removed surgically. The aim of this study was to determine the presence of and to identify microbes in 20 patients. Swab samples were taken from infected pulpa, from dental abscesses and from involved nasal sinuses. The samples were examined microbiologically and tested for aerobes and anaerobes at the same time. Infectious agents were found in 19 of 20 horses. In all, 27 different species of infectious agents were isolated, including both aerobic and anaerobic microbes. Fifteen patients (75%) showed a mixed flora. Further differentiation indicated a preponderance of the group of gram-negative obligatory anaerobic agents isolated from a total of 17 horses. In all these samples there was a high concentration of infectious agents of these genera, the most common of which were Prevotella spp (n = 16) and Fusobacterium spp. (n = 15). Pre-surgical antibacterial therapy is recommended to reduce the risk of intra- and/or post-surgical bacteraemia and its serious consequences. In light of these microbiological results and considering the high degree of resistance among all anaerobic microbes, all patients in this study were treated with Amoxicillin. PMID:14560441

    Two systems, radiometric BACTEC and biphasic MB-Check, based on liquid media proved to be significantly better than the egg-based solid media for the isolation of mycobacteria from clinical specimens. The difference in the rates of isolation of mycobacteria between two groups of media was more remarkable with smear-negative specimens. The time to the detection of the Mycobacterium tuberculosis complex with MB- Check was shorter than that with the 3% Ogawa egg method but longer than that with BACTEC. The polymerase chain reaction (PCR) using oligonucleotides based on the repetitive sequence (IS986) of M. tuberculosis as a primer and the Gen-Probe Amplified Mycobacterium Tuberculosis Direct Test (MTD), which combines an M. tuberculosis rRNA amplification method with the hybridization protection assay format, were evaluated for detection of M. tuberculosis in clinical samples. Although the sensitivities of the PCR and MTD appeared to be similar to that of culture with the MB-Check system, the two methods based on nucleic acid amplification should be very useful for rapid detection of M. tuberculosis infections without the long time required for culture of M. tuberculosis. Epidemiological studies with techniques which allow differentiation of strains within M. tuberculosis groups are important for limiting the dissemination of the disease. We analyzed six groups of small outbreaks of M. tuberculosis infections by restriction fragment length polymorphism (RFLP) analysis. Five showed identical fingerprints within each group, but one which as also suspected to have a common source of infection showed different banding patterns, emphasizing that RFLP analysis using IS986 as a probe is useful in epidemiological studies of tuberculosis.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7933779

  6. Bacteriological influence in the development of iron sulphide species in marine immersion environments

    International Nuclear Information System (INIS)

    Bacteria and microbiological consortia play an important role in the corrosion of steel in marine environments. There are laboratory based experimental findings and images verifying the presence of such consortia but there are few images in the literature of the interaction between bacteria and corrosion processes. The present paper considers the marine immersion corrosion of steel and presents a number of new images which appear to show steps in the metamorphosis of the iron in the steel to forms of iron oxide and to iron-sulphur compounds. These transformations appear to involve interaction with bacteria. Scanning electron microscope images were obtained for the specimens which were exposed to actual seawater conditions. Energy dispersive spectroscopy and X-ray diffraction were used to analyse the corrosion products. Inferences are made about the role of bacteria in the transformations from iron to iron-sulphur compounds

    Full Text Available A new case study method of assessment was developed to challenge advanced undergraduate biology majors interested in medical careers and allied health professions. This method is an alternative to traditional "unknown" identifications used in many microbiology laboratories. Students used various biochemical tests and selective media throughout the course to identify organisms cultured from their own bodies. In preparing a final assessment for the course, an assignment was developed to challenge the students to apply what they had learned in a medically relevant setting. Also of importance was the elimination of further biochemical testing by these students and prevention of contact with strict pathogens in this lab, due to budget and safety constraints, respectively. Each student was provided with a clinical specimen data record sheet and additional information about their "diseased patient". Students used analytical skills and critical thinking, as well as knowledge gained throughout the semester, to logically deduce the causative agent of disease in the mock patients. Students were required to: (i describe the steps in this logical deduction, (ii provide a brief overview of the characteristics and virulence factors of the organism(s, (iii investigate all disease(s caused by the organism, (iv describe symptomology of the patient in detail, and (v investigate disease treatment and prevention methods. The final assignment involved library and Internet research and culminated in a written report, which further developed writing and communication skills. Detailed descriptions of and materials for this assignment are provided along with an overall evaluation of this method after implementation.

    Full Text Available Mastitis is one of the most costly diseases of lactating animals. Bacteria constitute the common etiological agents of mastitis. In the present study, bacteria associated with mastitis were investigated and their susceptibility to various antibiotics was tested. Milk samples collected from different sources were subjected to different screening tests (White Side Test, Surf Test and California Mastitis Test. The samples found positive were cultured on tryptose agar, MacConkey’s agar, as well as blood agar, for bacterial isolation. The organism so isolated were identified and subjected to 12 commonly used antibiotics for determination of antibiogram. During the period of 52 months (July, 1997 to October, 2001, 6522 milk samples from cattle, buffaloes, sheep and goats were tested for mastitis, out of which 1512(23.18% were found positive. Growth of different bacteria was yielded by 236(15.16% out of the positive ones. Gentamicin, enrofloxacin, norfloxacin and kanamycin were found most effective drugs amongst the 12 antibiotics tested in vitro.

    Cystic fibrosis (CF) is characterized by chronic infection and inflammation of the airways. In vitro culture of select bacterial species from respiratory specimens has been used to guide antimicrobial therapy in CF for the past few decades. More recently, DNA sequence-based, culture-independent approaches have been used to assess CF airway microbiology, although the role that these methods will (or should) have in routine microbiologic analysis of CF respiratory specimens is unclear. We performed DNA sequence analyses to detect bacterial species in 945 CF sputum samples that had been previously analyzed by selective CF culture. We determined the concordance of results based on culture and sequence analysis, highlighting the comparison of the results for the most prevalent genera. Although overall prevalence rates were comparable between the two methods, results varied by genus. While sequence analysis was more likely to detect Achromobacter, Stenotrophomonas, and Burkholderia, it was less likely to detect Staphylococcus. Streptococcus spp. were rarely reported in culture results but were the most frequently detected species by sequence analysis. A variety of obligate and facultative anaerobic species, not reported by culture, was also detected with high prevalence by sequence analysis. Sequence analysis indicated that in a considerable proportion of samples, taxa not reported by selective culture constituted a relatively high proportion of the total bacterial load, suggesting that routine CF culture may underrepresent significant segments of the bacterial communities inhabiting CF airways.

    Full Text Available Aim: The present study was carried out to explore the potential source of contamination and the efficacy of different washing practices towards quality milk production. Materials and Methods: Probable sources of contamination viz. stored water, potable water, milker’s hands, milking pail, udder of individual buffalo and milk cans were subjected to different types of bacterial counts before the actual experiment to start. Twenty milch buffaloes thereafter were divided randomly into four treatment groups where washing was performed in each step viz. milker hands, udder of individual buffalo, milking pail and milk cans before milking either with water (T0: stored water, T1: potable water or sanitizers (T2: 200 ppm chlorine solution, T3: 50 ppm iodophore solution for 60 days. Bacterial counts again were performed for last 5 alternate days for all the sources involved along with the microbial load of raw milk. Data obtained were subjected to standard statistical analysis. Results: It was found that for all bacterial count stored water contributed significantly higher as compared to the potable water. Among the other potential sources of contamination (log/6 cm2, standard plate count (SPC and coliform count were significantly highest for milking pail (6.73±0.02 and udder of milch buffaloes (3.77±0.12, respectively, while for Staphylococci count both milking pail (3.24±0.02 and milking can (3.22±0.04 were contributed maximally (p0.05 for most of the parameters, even for the raw milk quality. Conclusion: Study revealed that milker hands, milking pails, udder of animals, milk cans and stored water used for washing of equipment are the potential source of contamination in raw milk. These were counted as critical point which needs attention for the production of high-quality milk. Potable water was found to be better than stored water. The use of either chlorine 200 ppm and iodophor 50 ppm is highly effective in reducing the bacterial population for quality milk production.

    2014-07-01

    Full Text Available Fixed-bed column studies were conducted to evaluate performance of Fe (III crosslinked alginate nanoparticles for the removal of pentavalent arsenic ions [As (V] from aqueous environments. The study involved observing the influences of column bed depth, influent As (V concentration and influent flow rates on the removal of arsenic ions. The total adsorbed quantity, equilibrium uptake and total percentage removal of arsenic were determined from the breakthrough curves obtained at different flow rates, initial metal ion concentration and bed heights. The results showed that column demonstrate fairly well performance at the lowest flow rate. Also, column bed capacity and exhaustion time were found to increase with increasing bed height. When initial metal ion concentration was increased from 0.5 mg/L to 1.5 mg/L, the corresponding adsorption bed capacity decreases from 0.066 to 0.022 mg/g. The Bed Depth Service Time (BDST model was used to analyze the experimental data and the model parameters were evaluated. Good agreement of the experimental breakthrough curves with the model predictions was observed.

    This paper summarizes over four years of studies and testing of a sinkhole/spring system in north Tampa. Sulphur Springs Pool delivers an average of 95 million l/d to the Hillsborough River, which is tributary to Tampa Bay. In 1986, owing to increasingly erratic bacterial levels at the natural bathing area adjacent to Sulphur Springs, the Hillsborough County Health Department closed the pool for swimming. The City of Tampa, Southwest Florida Water Management District (SWFWMD), Hillsborough County Environmental Protection Commission, and the United States Geological Survey have gathered data in an attempt to better understand the system and possible sources of contamination. The Sulphur Springs Action League is a civic group in the area, which has an objective of reopening the pool for recreational purposes. Environmental Engineering Consultants, Inc. provided pro bono technical assistance and expertise in assisting the Action League with its goal. The Action League obtained a grant from SWFWMD to outfit underwater divers for sinkhole exploration as well as water quality and dye trace analysis. The main suspects for bacterial contamination of the pool were two significant sinkholes located 1950 and 2300 m north of the spring. A series of dye tests and water-quality tests were performed. It was estimated that the underground velocity of water was between 90 100 m/h. Using a dye trace, bacteria testing, and travel time estimating, a new source of contamination was found in a Department of Transportation (DOT) stormwater retention basin in which a sinkhole had opened up and was receiving stormwater. The two significant sinkholes received stormwater from commercial and residential areas, and this stormwater brings a large amount of bacteria into the sinkhole, which funnels into the underground system and induces a bacteria spike at Sulphur Springs pool that exceeds the bathing water standards. The City of Tampa has constructed an experimental initial flush capture basin that will sand-filter stormwater to see if this will favorably affect bacteria levels. A mayor's task force in Tampa has recommended ultraviolet disinfection as an interim solution to the contamination problem.

    The presence of total and fecal coliforms, E. coli, Listeria sp and Salmonella sp. was evaluated in 65 samples of both commercial and homemade ice cream. 37.1% of homemade ice cream and 20% of commercial ice cream did not fulfill the international standard for total coliforms. At the same time 82.9% of home made samples and 56.7% of commercial ones presented fecal coliforms. E. coli was found in 51.4% of home made samples and 26.7% of commercial ones. Sixteen Listeria sp. isolates were obtained, 50% corresponded to Listeria monocytogenes and 50% to L. innocua. The overall presence of L. monocytogenes in ice cream samples was of 12.3% and it was isolated in all cases, from homemade ice cream samples. Salmonella was not isolated from the samples analyzed. Although the results obtained show an important improvement in the quality of ice cream, compared with a previous work done also in Costa Rica, further efforts shall be done, in order to offer safe products to consumers.

    Meat is worldwidely known to be a nutrient rich food. It provides valuable amounts of proteins,vitamins such as retinol and vitamin B12 and minerals namely iron, selenium and zinc with an increased bioavailability than found in other dietary sources [1]. Along the production chain, meat can get contaminated by a wide range of spoilage and/or pathogenic microorganisms from the farm, slaughtering environment and distribution. The actual number of foodborne infections attributable to meat is dif...

    The surface and bottom waters samples were collected from six locations in Xiamen west-em sea. The quantified estimation of bacterial production (3H-thymidine method) and observation ofbacterial heterotrophic activity (14C-glucose method) have been made in order to have a better under-standing of the role of marine bacteria and their activities. The results showed that the mean value ofbacterial heterotrophic activity was 9 × 108 cells/(L. h) in the surface waters and 2.6 × 108 cells/( L. h)in the bottom waters. The mean value of bacterial production was 38 × 108 cells/( L. h) in the surfacewaters and 7.1 × 108 cells/(L.h) in the bottom waters. The relationship between bacterial production,heterotrophic activity, POC and DOC measured during this survey were discussed. The good under-standing of the relationship between bacteria activity and total coliform was addressed.

  7. Radiological findings in children with respiratory syncytial virus infection: Relationship to clinical and bacteriological findings

    International Nuclear Information System (INIS)

    Respiratory syncytial virus (RSV) is a frequent cause of bronchiolitis leading to acute admission to hospital in the winter months. A wide range of findings accompanies this disease and the appearances are seldom completely diagnostic. Associated bacterial co-infections are common and we have shown an association with atelectasis among patients with pathogenic bacteria in the nasopharynx. (orig.)

    Full Text Available Evidences arising from epidemiological studies as well as from detailed experimental investigations have indicated that there is strong relationship between certain feed ingredients and incidence of bacterial infections. A total of two hundred and thirty nine (239 Poultry feed samples comprising of two hundred and four (204 commercially prepared feed and thirty five (35 self compounded feed were collected from seventy six (76 identified poultry farms in Sokoto metropolis over a period of 12 months for assessing their microbiological (bacterial quality. Of the total 80 questionnaires administered, 76 (95.00% were responded to. Of the respondents, 53 (69.74% indicated using commercially prepared feed while 23 (30.26% compounded the feed by themselves. Similarly, 30.57% of the farms visited store their feed either within the poultry pen or in an open space. Out of total (n=239, commercially prepared (n=204 and Self compounded (n=35 feed samples, 217 (90.79% samples yielded positive bacterial growth. Based on culture and identification, 263 bacterial species/genus were identified which include the following: Corynebacterium pyogenes (9; 3.42%, Bacillus subtilis (60; 22.81%, Enterobacter arrogenes (6; 2.28%, Escherichia coli (57; 21.67%, Listeria monocytogenes (19; 7.22%, Coagulase-negative staphylococcus (8; 3.04%, Pasturella multocida (3; 1.14%, Pseudomona aerogenosa (7; 2.66%, Proteus mirabilis (1; 0.38%, Proteus vulgaris (17; 6.46%, Salmonella spp. (10; 3.80%, Staphylococcu aureus (44; 16.73%, Streptococcus pyogenes (17; 6.46%, Yersinia enterocolitica (3; 1.14% and (2; 0.76% unidentified bacterial species. The presence of the above bacteria in all the feed samples calls for attention in the storage methods employed by the poultry and other livestock farmers, the warehouse condition, distributors and the sellers. This result could be used as a baseline data in setting public health standard for poultry feeds to achieve food security concern issues.

    1981-04-01

    Full Text Available 70 infertile males with epididymal tenderness, pus cells in the semen, and/or history of urinary tract infection were studied by semen culture examination. Significant growth of Streptococcus fecalis, Escherichia coli, coagulase positive Staphylococci, Proteus valgaris, Pseudomonas pyocyanea, and beta hemolytic Strepticocci was found in 42.9% of the cases. Most of the tested strains were sensitive to ampicillin, cotrimoxazole, nitrofurantoin, erythromycin, and chloramphenicol. In a control group of 20 healthy fertile males, only an insignificnat growth of Staphylococcus albus and Streptococcus facalis was found in 65% of the samples. Nonspecific seminal tract infection can be an important cause of male infertility. These infections may affect fertility in several ways: by damaging sperm, hampering their motility, altering the chemical composition of the seminal fluid, or by producing an inflammatory structure in the tract. Seminal infection could also be the cause of the chronicity of urinary tract infection by acting as the reservoir of infection.

    1984-11-01

    Bacteria were cultured for the first time from the teeth of a great white shark (Carcharodon carcharias). Isolates included Vibrio alginolyticus, Vibrio fluvialis, Vibrio parahaemolyticus, and other genera. All are common in the marine environment and some may be associated with wound infections in humans. Shark bite lacerations may serve as a source of these potentially infectious bacteria, particularly Vibrio spp., and should be treated immediately. Antibiotic susceptibility patterns are shown for representatives of Vibrio isolates and indicate that a variety of new agents may be appropriate chemotherapy for shark bite victims. PMID:6511869

  13. The bacteriology of the small intestinal mucosa of free-living reindeer

    1994-12-01

    Full Text Available Bacteria in close associaton with the intestinal mucosa are thought to protect the mucosa from pathogenic microorganisms. The pH of the small intestinal mucosa and the viable populations of aerobic and anaerobic bacteria associated with the proximal and distal jejunal mucosa, were measured in four free-living reindeer in winter. The anaerobic bacterial populations were characterized. The median pH of the mucosa of the duodenum was 6.6 (n=4 at point 0.2 m from the pyloric sphincter. The mucosal pH increased along the length of the intestine to 8.3 at 14 m and then decreased to 7.9 at 19.8 m from the pyloric sphincter. Examination by transmission electron microscopy and cultivation techniques failed to reveal any bacteria on the mucosa of the proximal jejunum in two of the animals. In two other reindeer the median anaerobic bacterial densities in the proximal jejunum ranged from 25-2500 cells/g mucosa. The median anaerobic bacterial populations in the distal jejunum ranged from 80 to 20000 bacteria/g mucosa (n=4. The anaerobic population of bacteria in the proximal jejunum was dominated by streptococci and unidentified gram positive rods. Bacteroidaceae, streptococci and unidentified gram positive rods were common in the distal jejunum. The low density and the species diversity of bacteria in the small intestine suggests that these microorganisms are inhibited by components in the natural winter diet of reindeer. Bacteria evidently play a minor role in protection of the mucosa of reindeer in winter.

    The fecal samples from 213 captive reptiles were examined, and 29 (13.61%) Salmonella enterica isolates were detected: 14/62 (22.58%) from chelonians, 14/135 (10.37%) from saurians, and 1/16 (6.25%) from ophidians. The isolates were distributed among 14 different serotypes: Miami, Ebrie, Hermannsweder, Tiergarten, Tornov, Pomona, Poona, Goteborg, Abaetetube, Nyanza, Kumasi, Typhimurium, 50:b:z6, 9,12:z29:1,5, and a non-motile serotype with antigenic formula 1,4,[5],12:-:-. Salmonella typhimurium and 50:b:z6 isolates showed the spv plasmid virulence genes, responsible of the capability to induce extra-intestinal infections. In some cases, pulsed field gel electrophoresis revealed different profiles for the strains of the same serotypes, showing different origins, whereas a common source of infection was supposed when one pulsotype had been observed for isolates of a serovar. Twenty-seven (93.10%) isolates showed resistance to one or more antibiotics. Ceftazidime was active to all the tested isolates, whereas the highest percentages of strains were no susceptible to tigecycline (93.10%), streptomycin (89.66%), and sulfonamide (86.21%).

    In April 2014, poor fertility in a major commercial goose breeder operation in California triggered the submission of six live affected Toulouse ganders ( Anser anser ) to the California Animal Health and Food Safety Laboratory, Turlock branch (University of California-Davis). Toulouse were principally affected among all breeds, and their egg fertility dropped from 65.7% to less than 33.9% in the first 40 days of the 2014 breeding season. The flock consisted of 410 adult birds, 90 males and 320 females, between 2 and 5 yr of age. Inspection of the flock revealed that 44.4% of the Toulouse ganders had severe phallic deformities that prevented them from mating. At postmortem examination, severe yellowish fibrocaseous exudate disrupted the architecture of the phallus and occasionally produced fistulating tracts through the wall of the organ. Microscopically, multifocal lymphoid nodules were noted in the mucosa and submucosa of the phallus and were associated with extensive granulomatous reaction, intralesional bacteria, and spermatozoa. Mycoplasma spp. were isolated from the phallus of affected and nonaffected birds, and PCR protocols targeting the 16S-23S ribosomal RNA intergenic spacer regions and the RNA polymerase beta subunit gene were performed to identify the isolates. Three distinct species were identified on sequencing and analysis using the National Center for Biotechnology Information basic local alignment search tool: Mycoplasma cloacale , Mycoplasma anseris , and an unknown novel Mycoplasma sp. Additionally, Pasteurella multocida , in combination with other bacteria, was also isolated from the phallic lesions and identified as serotype 3 with a DNA profile of 1511 (National Veterinary Service Laboratory). This is the first report of these Mycoplasma spp. and other bacteria associated with reproductive disease in ganders in the United States. PMID:27309284

    Full Text Available The objective of this research was to compare the chemical/physical parameters and bacterial qualities of selected surface water streams in Louisiana, including a natural stream (control and an animal waste related stream. Samples were collected and analyzed for fecal coliforms. Fecal coliforms isolated from these samples were identified to the species level. Chemical analysis was performed following standard test protocols (LaMotte 2002. An analysis of biological oxygen demand (BOD, chemical oxygen demand (COD, total organic carbon (TOC, total dissolved solids (TDS, conductivity, pH, temperature, ammonia nitrogen, nitrate nitrogen, iron, copper, phosphate, potassium, sulfate, turbidity, zinc and bacterial levels was performed following standard test protocols as presented in Standard Methods for the Examination of Water and Wastewater [9]. Results of the comparisons of the various surface water streams showed that phosphate levels, according to Mitchell and Stapp, were considered good for Lake Claiborne (control and Bayou Dorcheat. The levels were found to be .001 mg/L and .007 mg/L respectively. Other streams associated with animal waste, had higher phosphate levels of 2.07 mg/L and 2.78 mg/L, respectively. Conductivity and total dissolved solids (TDS levels were the lowest in Lake Claiborne and highest in the Hill Farm Research Station stream. It can be concluded from the data that some bacterial levels and various nutrient levels can be affected in water resources due to non-point source pollution. Many of these levels will remain unaffected.

    2016-01-01

    Full Text Available Introduction: This increased risk of bacterial infections in the cancer patient is further compounded by the rising trends of antibiotic resistance in commonly implicated organisms. In the Indian setting this is particularly true in case of Gram negative bacilli such as Escherichia coli, Klebsiella pneumoniae and Acinetobacter spp. Increasing resistance among Gram positive organisms is also a matter of concern. The aim of this study was to document the common organisms isolated from bacterial infections in cancer patients and describe their antibiotic susceptibilities. Methods: We conducted a 6 month study of all isolates from blood, urine, skin/soft tissue and respiratory samples of patients received from medical and surgical oncology units in our hospital. All samples were processed as per standard microbiology laboratory operating procedures. Isolates were identified to species level and susceptibility tests were performed as per Clinical Laboratory Standards Institute (CLSI guidelines -2012. Results: A total of 285 specimens from medical oncology (114 and surgical oncology services (171 were cultured. Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus and Acinetobacter spp. were most commonly encountered. More than half of the Acinetobacter strains were resistant to carbapenems. Resistance in Klebsiella pneumoniae to cephalosporins, fluoroquinolones and carbapenems was >50%. Of the Staphylococcus aureus isolates 41.67% were methicillin resistant. Conclusion: There is, in general, a high level of antibiotic resistance among gram negative bacilli, particularly E. coli, Klebsiella pneumoniae and Acinetobacter spp. Resistance among Gram positives is not as acute, although the MRSA incidence is increasing.

    Foods grown in organic production systems have been described as representing an increased risk to public health compared with foods from conventional production. Leafy vegetables (spinach, romaine lettuce, and green sesame leaves) grown in organic and conventional systems were collected from various areas in Korea and examined using standard culture methods to compare the microbiological quality of the produce grown in the two agricultural systems. The 354 samples of these leafy vegetables were analyzed for levels of indicator bacteria (aerobic bacteria, coliforms, and Escherichia coli) and the prevalence of the pathogens Staphylococcus aureus, E. coli O157:H7, Listeria monocytogenes, Bacillus cereus, and Salmonella. Aerobic bacteria and coliforms were detected in all vegetable types, but nonpathogenic E. coli was below the limit of detection in all samples. B. cereus was the most prevalent pathogen, found on 7 (11.1%) of the 63 organic spinach samples. The prevalence of S. aureus was highest in organic sesame leaves; it was found on 5 (8.0%) of the 63 samples. The prevalence of L. monocytogenes was highest on organic romaine lettuce and spinach; it was found in 4 (6.4%) of 63 samples of each type of vegetable. E. coli O157:H7 found on only 1 (1.58%) of 55 conventional spinach samples. These results suggest that farming type at most only slightly affects the hygienic quality of leafy vegetables, and no effect was found for sample collection area. Salmonella was not isolated from any of the conventional or organic leafy vegetables. These results do not support the hypothesis that organic produce poses a substantially greater risk of pathogen contamination than does conventional produce. PMID:25198606

    Introduction Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease of unclear etiology. The role of bacteria in the pathogenesis of disease remains controversial. Materials and Methods Specimens were obtained from 22 HS patients by direct percutaneous needle aspiration. The collected material was cultured in aerobic and anaerobic conditions, and sensitivity tests were performed. Results Of the 22 patients, 32% were culture negative and 68% were culture positive. A total of 16 isolates was obtained, 14 aerobic and 2 anaerobic. Aerobic bacteria were present in 86% of the specimens, whereas only anaerobic bacteria were isolated in 7%. The predominant aerobic species were Proteus mirabilis, Staphylococcus haemolyticus and Staphylococcus lugdunensis. The isolated anaerobic bacteria were Dermacoccus nishinomiyaensis and Propionibacterium granulosum. Conclusion A variety of aerobic and anaerobic bacteria was isolated from the HS lesions of our patients. In contrast to previous studies, fewer patients were found to be culture positive, and Staphylococcus aureus was isolated in only 1 of them. More studies are necessary to elucidate the controversial role of bacteria in the pathogenesis of HS. PMID:27170935

    Full Text Available Chronic Suppurative Otitis Media (CSOM is one of the most common chronic diseases of childhood. It is one of the common causes of deafness and can also cause permanent perforation. AIM This study was carried out to know the bacterial aetiology of CSOM and their antibiotic susceptibility pattern. MATERIALS AND METHODS Hundred patients with symptoms of CSOM who were not on antibiotics were included in the present study. Gram stain, culture and sensitivity and biochemical reactions were carried out to identify the organism and to assess their antibiotic susceptibility pattern. RESULTS The most common organism isolated in this study was Staphylococcus aureus (45.6% followed by Pseudomonas aeruginosa (34.7%, Klebsiella pneumoniae (6.5%, Proteus mirabilis (4.3%, Enterococcus fecalis (2.1%, Citrobacter koseri (2.1%, Acinetobacter baumannii (2.1% and Bacteroides (2.1%. Staphylococcal isolates showed highest susceptibility to commonly used antibiotics, gentamycin, ciprofloxacin. Most of the gram negative isolates showed susceptibility to amikacin, ciprofloxacin, third generation cephalosporins. CONCLUSION The study of microbial pattern and their antibiotic susceptibility determines the prevalent bacterial organisms causing CSOM in local area and helps to decide empirical treatment of otitis media and its complications for successful outcome, thus to prevent the emergence of resistant strains.

    Sera from 2,630 apparently normal adult camels (Camelus dromedarius) raised in central Saudi Arabia (Riyadh and Al-Kharj cities) were examined serologically by the Rose Bengal and standard United States of America Brucella plate agglutination tests. The overall seroprevalence of brucellosis in the restricted populations of tested camels was 8%. The seroprevalence of brucellosis among camels raised in small numbers in the backyards of 24 houses in Riyadh and those intensively raised on one large camel farm near Al-Kharj were 4.3% and 8.6% respectively. Fresh milk samples from 100 brucellosis seropositive camels from Riyadh and Al-Kharj were cultured on Brucella-selective media. Brucella melitensis biovars 1 and 2 were isolated and identified from 26 camels. Epidemiologically, brucellosis in camels in central Saudi Arabia appeared to be connected with B. melitensis infection of sheep and goats, and also represents a serious public health risk.

  10. Comparative bacteriological investigations of sewage sludge after treatment with gamma-irradiation

    International Nuclear Information System (INIS)

    Bacterial investigations of the hygienic effect of Gamma-irradiation on sewage sludge were carried out under practical conditions in a sewage plant of conventional construction, (mechanical-biological treatment), containing an irradiation-plant (Gamma-irradiation source Cobalt 60). - The mechanical-biological treatment reduces the bacterial-count by an average of 3 log, Enterococci by 1-2 log and Enterobacteria by 3-4 log. The following irradiation of the digested sludge further reduced surviving bacteria by 1-2 log for the bacterial count, 2-3 log for Enterococci and 5-6 log for Enterobacteria. - Salmonella were isolated from 32 of 34 raw sludge samples and from 128 samples of non-irradiated digested sludge 117 were positive. 27 out of 38 from drying-bed, containing non-irradiated digested sludge were Salmonelle positive. After treatment of digested sludge in the irradiation plant, with 300 krad for 75 min, of 55 sludge batches 165 samples were taken. 163 proved Salmonella negative. - After storage at 370C and 15-180C in different containers the irradiated digested sludge remained negative for Salmonella. During the storage of irradiated sludge in drying beds under practical conditions, from 2 out 28 samples, taken at different times of year, Salmonella were isolated. Repeat investigations proved negative. - Model experiments with 15 Salmonella pure-cultures produced - with irradiation in the plant of 300 krad/75 min - a reduction of the count by around 5.2 - 7.9 log (average 6.3 log). - The experimental results show not only an inadequancy of mechanical-biological treatment but also the good hygienic effect achieved by Gamma-irradiated under practical conditions.

    Full Text Available This study was conducted to determine the composition of staghorn stones and to assess the proportion of infected stones as well as the correlation between infection in the stones and bacteria grown in urine. Samples of 45 consecutive stones removed through anatrophic nephrolithotomic procedures were taken from the operation site and samples of urine were obtained by simultaneous bladder catheterization. The frequency of infection in the stones and correlation between infection of stone and urine samples were determined with respect to the composition of the stones. Twenty-two males and 23 females, with respective mean ages of 48.3 ± 15.6 years and 51 ± 7.4 years, were studied. The stone and urine cultures yielded positive results in ten and 16 patients, respectively, of a total of 45 patients (22.2% and 35.5%, respectively. Calcium oxalate was the main constituent of staghorn stones, seen in 31 patients (68.8%, uric acid in 12 patients (26.6% and struvite and/or calcium phosphate in 11 patients (24.4%. In seven of ten stones with bacterial growth, bacteria were isolated from urine cultures as well, which accounted for a concordance rate of 70%. The bacteria grown in the stone were the cause of urinary tract infection (UTI in 43.5% of the cases. Stone infection was significantly associated with UTI (OR = 6.47; 95% CI 1.43-31.7, P = 0.021 and presence of phosphate in the stones (OR = 18, 95% CI 3.28-99.6, P = 0.0006. E. coli was the most common bacteria grown from the stones, and was isolated in 50% of the cases; Ureaplasma urealyticum was the most common organism causing UTI, grown in 62.5% of the urine samples. There was a high concordance rate between bacteria in the stones and urine. These findings indicate that the urine culture can provide information for selection of an appropriate anti-microbial agent for stone sterilization. In addition, preventing re-growth or recurrence of stones and treatment of post-surgical infections would be facilitated based on the results of the urine culture.

    Full Text Available The potability and qualities of Olumirin waterfall, Erin-Ijesa were investigated by determining the total bacteria and coliform count with antibiotic susceptibility of the isolated bacteria and physico-chemical qualities of the water samples. Total bacteria and coliform enumeration were determined using pour plating and multiple tube techniques, the antibiotic susceptibility were carried out using disc diffusion method, while physico-chemical and mineral studies were also carried out using standard methods. The mean total viable count of the water samples ranged 14.8 x 102 CFU.ml-1 - 21.3 x 103 CFU.ml-1 while the coliform count ranged 13 -175 MPN/100ml. The identified bacteria isolates and their percentage distribution were E.coli (43.1%, Klebsiella spp (20.7%, Proteus spp (12.1%, Salmonella spp (6.99%, Pseudomonas spp (5.17%, Shigella spp (6.9%, and Enterococcus spp (5.17 %. Antibiotic resistance shown by bacteria isolates were exhibited as follow; Nalixidic acid (31%, Ampicilin (76%, Cotrimoxazole (60%, Gentamicin (19%, Nitrofurantoin (24%, Colitin (48%, Streptomycin (34% and tetracycline (52%. 82.8% of the isolate exhibited multiple antibiotic resistance. The physico-chemical analysis also revealed the presence of some mineral elements in the water samples. The mineral value of the water samples include; magnesium (84.8 - 93.4 mg.L-1, phosphate (12.6 - 17.1 mg.L-1, sodium (47.8 - 87.6 mg.L-1, potassium (76.6 - 104.5 mg.L-1, chloride (59.0 - 90.2 mg.L-1, zinc (0.75 - 1.82 mg.L-1, lead (0.12 - 0.33 mg.L-1, iron (0.52 - 0.60 mg.L-1, copper (0.12 - 0.27 mg.L-1 while nickel and arsenic were not detected in any of the water samples. Comparing the experimental results with the international water standard for natural water, the waterfall is not fit for consumption or for any domestic purpose unless being treated. Also, problems that may arise from the resistance bacteria strains can be tackled while the new antibiotics can also be developed.

    International Nuclear Information System (INIS)

    Objective: To identify the bacterial pathogens causing paediatric septicaemia in Kabul and to determine their antibiogram to improve empirical antibiotic therapy. Study Design: Cross-sectional study. Place and Duration of Study: Microbiology Laboratory of FMIC, Kabul, Afghanistan, from January 2010 to June 2012. Methodology: Blood cultures from suspected cases of sepsis were processed in BD (Becton Dickinson, USA) for culture BACTEC 9240 Blood Culture System. Positive growths were examined and isolates were identified by conventional biochemical tests. Bacteria were identified to the species level using various Analytical Profile Index (API) identification strips. Antibiotic susceptibility testing was performed by modified Kirby-Bauer disk diffusion method. Drug resistant strains were studied for extended spectrum beta lactamase (ESBL) production by combination disk method and for methicillin resistant Staphylococcus aureus (MRSA) by Cefoxitin disk diffusion method. Results: Out of a total 3360 blood cultures received from in-patients, 410 yielded monomicrobial growth; hence the frequency of positive blood culture was 12.2%. Out of a total 410 isolates, 212 (51.71%) were gram-negative bacilli and 184 (44.88%) were gram-positive cocci. In addition, 14 (3.41%) Candida species were also isolated. The frequently isolated species of gram-negative bacteria belonged to Enterobacteriaceae and included 66 Klebsiella (16.1%), 42 Enterobacter (10.2%), 35 Escherichia (E.) coli (8.5%) and 16 Serratia (3.9%) species. In addition, 21 (5.12%) Pseudomonas species were also isolated. Correspondingly, amongst gram-positive cocci, the most frequently isolated species were 108 coagulase-negative Staphylococci (26.34%) followed by 49 Staphylococcus aureus (11.95%) and 21 Streptococcus species (5.12%). Among gram-negative isolates, those that produced ESBL i.e., 110 out of 212 (51.9%) were found to be multidrug-resistant and showed high resistance to commonly used antibiotics namely Ampicillin, Gentamicin, 3rd generation Cephalosporins, Fluoroquinolones and Co-trimoxazole. Most of the isolates were susceptible to Imipenem (200/212, 94.3%), Amikacin (172/212, 81.1%) and Fosfomycin (166/212, 78.3%). Amongst gram-positive cocci, majority were resistant to Penicillin, Gentamicin, 3rd generation Cephalosporins, Fluoroquinolones and Cotrimoxazole. However, most were sensitive to Vancomycin (183/184) Pristinamycin (161/184, 87.5%) and Fosfomycin (134/184, 72.8%). All Staphylococci were resistant to Penicillin and 80/157 (51%) were MRSA. Conclusion: Klebsiella, E. coli, Enterobacter and Staphylococci remain the principal organisms responsible for blood stream infection in a paediatrics tertiary care setting in Kabul. The most sensitive among the tested antibiotics for gram negative organisms were Imipenem, Amikacin, and Fosfomycin and for gram-positive organisms were Vancomycin, Pristinamycin and Fosfomycin.

    With the increasing popularity of ice cream in the nineteenth century, the incidence of foodborne illness attributed to this dessert exploded. Struggling to understand the causes of the mysterious and sometimes lethal ailment called "ice cream poisoning," Victorian doctors and scientists advanced theories including toxic vanilla, galvanism in ice cream freezers, and extreme indigestion. In the late 1880s Victor C. Vaughan's argument that ice cream poisoning could be attributed to the ptomaine "tyrotoxicon" received widespread acceptance. To date historians have neglected the role played by the ptomaine theory of food poisoning in shaping the evolution of both scientific thinking and public health in the late nineteenth century. The case of ice cream poisoning illustrates the emergence, impact, and decline of the ptomaine idea. PMID:23241909

    Full Text Available Ornithobacterium rhinotracheale (ORT is a respiratory pathogen which has been isolated throughout the world from numerous bird species. The present study was designed to isolate and characterize the ORT from domestic turkeys, quails and pigeons. For this purpose, 250 samples from each bird species (turkey, quail and pigeon with or without respiratory signs were tested by taking of tracheal swabs. In addition, respiratory tissue samples (tracheal and lung, from 250 slaughtered turkeys, 50 slaughtered quails and 100dead pigeons were also subjected to culture for ORT as tracheal swabs. Respiratory tissues were also tested for bacterial DNA by using polymerase chain reaction (PCR. In general, 30 isolates including 4 isolates from turkeys, 3 isolates from quails and 23 isolates from pigeons were identified as ORT by bacteriologicalmethod and then confirmed by PCR. Bacterial DNA was detected in 20%, 50% and 35% of respiratory tissues in turkeys, quails and pigeons respectively. Five ORT isolates from pigeon and all four isolates from turkey showed smaller colony size, while other isolates had larger colonies when cultured in blood agar. Fifty percent of the isolates with larger colony but none of the isolates with small colony size could agglutinate red blood cells (RBCs. All of the isolates were sensitive to danofloxacin and chloramphenicolwhile more than 90% of pigeon isolates were resistant to ampicillin. All of turkey and quail and 30% of pigeon isolates were resistant to tetracycline. Our ORT isolates showed high identity (98%- 100% insequence of 16S rRNA gene to related data in GeneBank.

    Full Text Available Diabetic foot disease is a major medical, social, and economic problem. This retrospective study assessed the profile of diabetes mellitus patients with foot ulcers in the University of Calabar Teaching Hospital (UCTH, Nigeria. Admission records of all patients admitted unto the medical wards of UCTH over a 5 year period were analysed. The records of diabetic patients were retrieved. Data on patient characteristics and possible risk factors for diabetes mellitus foot ulcers was extracted. Of the 3,882 patients admitted, 297 (7% were on account of complications of diabetes mellitus. Foot ulcers accounted for 63 (21.2% of all diabetic admissions. The elderly constituted the majority of patients admitted with foot ulcers. The average duration of stay of diabetics with foot ulcers was 38.5 days. Diabetics admitted for other conditions had average duration of admission of 15.8 days. Staphylococcus aureus was the commonest organism isolated from swabs of foot ulcers. Most of the organisms identified from ulcer swab cultures were sensitive to quinolones and resistant to penicillins. These diabetic foot ulcers were significantly associated with peripheral sensory neuropathy, peripheral vascular disease, intermittent claudication, and walking barefoot. An effective diabetes foot programme is required to address these risk factors and reverse the current trend.

    2012-01-01

    Full Text Available A 6-year-old Lusitano stallion was referred to our centre due to an enlarged left testicle. Anamnesis indicated that the stallion had a chronic hypertrophy of the left testicle, with no apparent ill effect on work (dressage training or semen production. Prolonged use of anti-inflammatory drugs (NSAIDs and antibiotics were probable. Upon examination of the animal, it was found that clinical signs were compatible with chronic testicular degeneration or fibrosis. Ultrasound scanning did not evidence the exuberant macroscopic lesions seen upon hemicastration of the left testicle, but it showed in the left spermatic cord a conspicuous absence of the typical hypoechogenic areas representing the pampiniform plexus. Swabbing of the penis, prepuce, and distal urethra resulted in the isolation of Rhodococcus equi and Corynebacterium spp. However, histopathological examination did not support infectious orchitis as cause of the lesions and no bacterial growth was obtained from swabbing of the parenchyma in the excised testicle. Histopathological findings were compatible with chronic orchitis with fibrosis and necrosis, probably secondary to ischemia of the testicular parenchyma. After hemi-castration, the stallion resumed semen production at acceptable levels.

    A prospective study was conducted in 3056 live-born infants delivered at the Jeanneade-Flandre maternity hospital of the Lille Teaching Hospital between January and August 1997. Clinical, laboratory test, and microbiological test findings were compared. A cohort of 1003 infants who remained in the maternity ward but were considered at increased risk of maternofetal infection (MFI) based on history and/or obstetrical criteria and/or neonatal criteria underwent routine collection of specimens including gastric fluid, auricular and anal swabs, amniotic fluid, and placental fragments. Microscopic examination of gastric fluid smears, the first result available to the clinician, was found to have 27.5% sensitivity (983 samples). Positive predictive value (PPV) was only 17.8% because of a high rate of colonization (16.8%), defined as absence of clinical symptoms and three peripheral specimens positive for the same organism. However, negative predictive value (NPV) was as high as 99.8% as a result of high sensitivity (97.8%) in the infected neonates. The gastric fluid smear was positive in 30% and 35% of neonates born to mothers with hyperpyrexia during early and late labor, respectively, and in 42% of neonates born to mothers with a history of group B streptococcus carriage during the pregnancy. Forty-two per cent of neonates with a history of fetal tachycardia had a positive gastric fluid smear. Diagnostic criteria for infection were three peripheral specimens positive for the same organism, C-reactive protein elevation, and/or one or more clinical signs suggestive of infection, and/or a positive central specimen (blood, CSF). The infection rate in infants who remained in the maternity ward was 1.6%. The most common causative organisms were group B streptococci. These findings illustrate the useful contribution of gastric fluid smears to the early diagnosis of MFI and confirm the predominant role of group B streptococci. PMID:10573697

This present study aims to find out the bacterial load in throat infections as well as their susceptibility pattern in patients attending Central Referral Hospital, Tadong, Sikkim.Method: A total of 55 symptomatic patients having throat infections attended Central Referral Hospital Sikkim, among which 28 were males and 27 were females. A total of 55 throat swabs were collected from the patients with symptoms ofpharyngitis. Results: Out of 55 samples, culture was positive in 37 samples. Twenty one strains of Staphylococcus aureus, 13 strains of Streptococcus pyogenes, 1 strain of Pseudomonas aeruginosa and 2 strains of Proteus spp. were isolated. The isolation rate of Staph.aureus was found to be statistically significant when compared between the isolation rate of Ps.aeruginosa, Stp. pyogenes and Proteus spp. 3 isolates of Staph. aureus were sensitive to penicillin, 1 isolate was moderately sensitive and 17 isolates were resistant. 12 strains of Staph.aureus were sensitive to methicillin. Methicillinresistant was seen in 9 strains of Staph. aureus. The strains of Stp. pyogenes isolated were either moderately sensitive or resistant to the used antibiotics, it was not sensitive to any of the used antibiotics. It was moderately sensitive to amoxiclave, clarithromycin, erythromycin and resistant toclindamycin and cefuroxime. 100% strains of Ps. aeruginosa were resistant to ciprofloxacin, gentamicin, piperacillin, ticarcillin, tobramycin and the strains were sensitive only to imipenem (100%. Further 100% strains of Proteus spp.were sensitive to cefuroxime, azithromycin, amoxicillinand cephalexin.Conclusion: Our study showed a high rate of monomicrobial infection.

    Full Text Available In the present study the effects on shelf life and sensory acceptance of gamma-irradiated refrigerated poultry breast fillets subjected to modified atmosphere packaging (80% CO2/20% N2 or vacuum were investigated. After irradiation with 2 kGy, sensory acceptance tests and monitoring of bacterial growth were performed in order to determine the sanitary quality of the samples. It has been found that irradiation, used in combination with modified atmosphere packaging, can double the shelf life of refrigerated poultry breast fillets by reducing the populations of aerobic mesophilic and psychrotrophic bacteria, enterobacteria, coliforms, Listeria spp. and Aeromonas spp., without significantly modifying its color or its overall appearance, the lactic acid bacteria being the most resistant to exposure to radiation and carbon dioxide.

  18. Experience with a pilot plant for the irradiation of sewage sludge; bacteriological and parasitological studies after irradiation

    International Nuclear Information System (INIS)

    Reduction of viable micro-organisms could be achieved by irradiation of sewage sludge in a pilot plant (60Co gamma-radiation 300 krad, 300 min.). The reduction amounted to an average of 2 log with Enterococces and total bacterial count and to 5 log with Enterobacteriaceae. Out of 23 sludge batches from digestor II, 21 were free of Salmonella after irradiation. Of 7 sludge batches from digester I with higher level of Enterobacteriaceae and Salmonellae 5 batches still contained Salmonella after treatment. By making some alterations in the pipe system and reloading futher Cobalt 60-sources the duration of irradiation could be reduced to 65 min. while maintaining the dose level of 300 krad. Employing this altered procedure 16 batches from digestor II and 4 from digestor I were irradiated to date. Only in one of 60 samples was Salmonella detectable. The hygenic effects of the irradiation unit were confirmed by means of a model experiment with bacterial pure cultures. Microorganisms of different species as well as strains of the same species differ in their radiation-sensitivity. Parasitological experiments were conducted with Ascaris suum ova. No embryonation was noted after radiation treatment at a dose of 300 krad. (author)

    Background: Sepsis is one of the most common causes of neonatal hospital admissions and is estimated to cause 26% of all neonatal deaths worldwide. While waiting for results of blood culture, it is necessary to initiate an empirical choice of antibiotics based on the epidemiology of causative agents and antibiotic sensitivity pattern in a locality. Objective: To determine the major causative organisms of neonatal sepsis at the Niger Delta University Teaching Hospital (NDUTH), as well as their antibiotic sensitivity patterns, with the aim of formulating treatment protocols for neonates. Methods: Within a 27-month period (1st of October 2011 to the 31st of December 2013), results of blood culture for all neonates screened for sepsis at the Special Care Baby Unit of the hospital were retrospectively studied. Results: Two hundred and thirty-three (49.6%) of the 450 neonates admitted were screened for sepsis. Ninety-seven (43.5%) of them were blood culture positive, with 52 (53.6%) of the isolated organisms being Gram positive and 45 (46.4%) Gram negative. The most frequently isolated organism was Staphylococcus aureus (51.5%) followed by Escherichia coli (16.5%) and Klebsiella pneumoniae (14.4%). All isolated organisms demonstrated the highest sensitivity to the quinolones. Conclusion: Neonatal sepsis is a significant cause of morbidity among neonates admitted at the NDUTH. There is a need for regular periodic surveillance of the causative organisms of neonatal sepsis as well as their antibiotic susceptibility pattern to inform the empirical choice of antibiotic prescription while awaiting blood culture results.

    In the last years, there has been an increase in the production, industrialization and consumption of goat's milk and derivate products, including cheese, worldwide. Nevertheless, in Costa Rica there is no study of these products, reason why the objective of this work was to determine the microbiological characteristics of goat's milk and fresh cheese distributed in the Metropolitan Area of San José, Costa Rica, in order to evaluate its impact in the economical field and as a potential risk for Public Health. A total of 25 raw goat's milk samples, obtained by manual milking from 5 different producers tested in five different dates and 15 cheese samples, elaborated with pasteurized milk, commercially available and coming from three different producers were analyzed. The study included the analysis of spoilage bacteria (total aeobic count and lactic bacteria count), indicators of hygiene (total coliforms), fecal contamination (fecal coliforms), manipulation (Staphylococcus aureus) and pathogens (Listeria monocytogenes and Salmonella spp). High results were obtained for the total aerobic count and lactic bacteria count of the milk and cheese samples, showing a reduced shelf life. Total coliforms, in limits beyond the established ones by the Costa Rican legislation for human consumption raw milk, were found in 100% of milk samples, as well as for fecal coliforms in 76% of them. All cheese samples, except one, were negative for these indicators, suggesting good manufacturing practices. S. aureus counts were low and both Salmonella spp. and L. monocytogenes were not isolated from samples analyzed. PMID:18833996

    Full Text Available Twenty-three reindeer bulls, aged 2-3 years, fed during two winter months at the Vuolda reindeer research station in Arjeplog, Sweden, were used in the study. The first group of eight reindeer was moved from their feeding corral to a selection corral, captured by lasso and stunned with a captive bolt outside the selection corral. The second group of seven reindeer was moved to the selection corral, captured by lasso and restrained, after which they were loaded onto a lorry- and transported for 1 hour and then slaughtered. The third group of eight reindeer was moved to the selection corral and herded directly onto the lorry, without any manual handling. They were transported for 5 h and then slaughtered. In both transport groups, four reindeer were fitted with pre-programmed automatic blood sampling equipment (ABSE. ABSE sampled blood at predetermined times via a jugular vein catheter. Ultimate pH-values in three muscles (Mm. longissimus, triceps brachii and biceps femoris were significantly lower in the group carefully handled and transported for 5 h compared with the other two groups. The physiological mechanisms behind these results are discussed. Samples from M. semimembranosus were collected at slaughter and after 2, 6 and 10 days of refrigerated storage (+4 °C. The samples were analysed for total counts of aerobic bacteria (pour-plated in Tryptone Glucose Extract Agar, Difco, incubated at 20 °C and 30 °C, respectively for 72 h, coliform bacteria 37 °C (pour-plated in Violet Red Bile Agar, Oxoid, incubated at 37 °C for 24 h, Enterococci (surface-plated onto Slantez and Bartley Agar, Oxoid, incubated at 44 °C for 48 h and Bacillus cereus (surface-plated onto Blood Agar Plates (Blood Agar Base, Difco, supplemented with 5% defibrinated horse blood 30 °C for 24 h. All samples fell in the range 'fit for consumption'. At slaughter, there was no difference in ASAT activity, urea and Cortisol concentrations between the two transported groups. However, the plasma ASAT activity and urea concentrations at slaughter were significantly lower in the non-transported group. In both transport groups, the plasma Cortisol concentrations increased during loading onto and unloading from the lorry. Abomasal lesions were observed in all treatment groups. It was concluded that reindeer showed an acute stress response to manual handling and transport.

    Full Text Available Introduction: Septicemia remains a significant cause of morbidity and mortality in the newborn. Shortly after the introduction of potent and broad-spectrum antibiotics, the emergence of resistant strains became a major problem in various Intensive care units. So, determination of bacterial etiology and antibiotic susceptibility patterns of isolates from septicemia in Neonatal intensive care units (NICU is now crucial to abate neonatal mortality. This study was under taken to know the bacterial etiology of septicemia in neonate and antibiotic susceptibility pattern of the isolates. Materials and Methods: During Jan-2011 to June -2011, 626 Blood samples were collected aseptically from newborns admitted with sepsis in NICU, Sheth Vadilal Sarabhai General Hospital, Ahmadabad and processed by standard conventional method. Antibiotic susceptibility pattern of isolates was studied by Kirby Bauer Disc diffusion technique. Results: Total 626 samples were received during the study period of which 107 (17.09% samples were found to be positive. Out of 107 isolated organisms 59 (55.14% were Klebsiella sp., 11 (10.28% Staphylococcus aureus, 10 (9.34% Escherichia coli, 9 (8.41% Coagulase negative staphylococci, 7 (6.54% Pseudomonas aeruginosa, 5 (4.67% Enterobacter sp.5, 4(0.63% Enterococcus sp., 1 (0.93% Acinetobacter baumanii and 1 (0.93% Proteus-mirabilis. Majority of organisms isolated were resistant to commonly used antibiotics. Imipenem showed 100% sensitivity for gram negative organisms. Methicillin resistance was found in 9.01% Staphylococcus aureus. Isolated all Enterococcus sp. were sensitive to vancomycin and high level gentamycin. Conclusion: Multi-drug resistance organisms were isolated from septicemia in neonates. This study would guide the clinicians to formulate appropriate treatment strategy as well as to take various preventive measures which ultimately would help to decrease neonatal mortality.

  8. Bacteriological investigations of the irradiation of fresh fish using a new classification scheme for bacteria of the fish skin

    International Nuclear Information System (INIS)

    Investigations were made on the effect of irradiation with 36, 72, 108 and 144 kr, carried out once and twice, on the bacterial flora of the skin of red fish on the day of catching and after 9, 16 and 23 days of storage in ice. With an initial total count of the fish of 13,700 bacteria/cm2 of skin surface irradiation with 36 kr (108 kr) on the day of catching caused a reduction of the total count to 11% (1.3%) of the nonirradiated fish on the 9th day of storage. Nearly all differences disappeared by the 16th day. A second irradiation with 36 kr and 108 kr on the 9th day reduced the bacterial count on a large scale by which on the 16th day the total count of these fishes was lower than that of the nonirradiated fish on the 9th day. Later on the differentiation disappeared quickly but there were small differences unlike the nonirradiated fish on the 23rd day. The rapid equalization during the last storage period is possibly only typical of the storage in boxes. A scheme for the characterization of types of spoilage bacteria recently established and based on the bacterial attack on leucine, β-alanine, creatine, creatinine and cystine yielded the following results: The different Pseudomonas types were reduced much more than Achromobacter types. The irradiation effect does not only consist in a reduction of the general total count of bacteria but also in the selective destruction of the most active spoilage bacteria with a very extensive enzymatic pattern which concerns many organic nitrogen compounds in the tissue of fish. By means of a sub-group of Pseudomonas and several maturity stages of the bacterial populations a 7 days delay of the bacterial evolution, caused by the second irradiation with 36 kr, could be observed. The useful effect of irradiation carried out twice with doses about 50 kr was discussed and estimated at a 10-12 days delay of the bacterial spoilage. (orig./MG)

    Distribution of microorganisms were examined for the bucky tables in the radiology rooms of the department of radiological technology, the aprons, handles of various apparatus, handles of mobile radiological apparatus, and hands of the radiological technologists. As a result, relatively larger amounts of bacteria were found on the handles of the mobile radiological apparatus and the aprons. Among the isolated bacteria, Acinetobacter baumanni (7.3%), Klebsiella pneumoniae (6.7%), Staphylococcus aureus (3.9%), Serratia liquefaciens (1.7%), Enterobacter cloaceae (0.6%), Providenica rettgeri (0.6%) are known as the cause of nosocomial infection (hospital acquired infection). In addition, similar colonies were also found on the hands of the radiological technologists such as microorganisms of Klebsiella pneumoniae (8.4%), Staphylococcus aureus (6.6%), Yersinia enterocolotica (5.4%), Acinetobacter baumanni (4.2%), Enterobacter cloaceae (2.4%), Serratia liquefaciens (1.8%), Yersinia pseuotuberculosis (18%), Enterobacter sakazakii (1.2%), and Escherichia coli (0.6%). In particular, this result indicates clinical significance since Staphylococcus aureus and Escherichia coli show strong pathogenicity. Therefore, a continuous education is essential for the radiological technologists to prevent the nosocomial infection.

    Introduction Biomarkers are needed to monitor tuberculosis (TB) treatment and predict treatment outcomes. We evaluated the Xpert MTB/RIF (Xpert) assay as a biomarker for TB treatment during and at the end of the 24 weeks therapy. Methods Sputum from 108 HIV-negative, culture-positive pulmonary TB patients was analyzed using Xpert at time points before and during anti-TB therapy. Results were compared against culture. Direct Xpert cycle-threshold (Ct), a change in the Ct (delta Ct), or a novel “percent closing of baseline Ct deficit” (percent closing) were evaluated as classifiers of same-day and end-of-treatment culture and therapeutic outcomes. Results Xpert was positive in 29/95 (30.5%) of subjects at week 24; and positive one year after treatment in 8/64 (12.5%) successfully-treated patients who remained free of tuberculosis. We identified a relationship between initial bacterial load measured by baseline Xpert Ct and time to culture conversion (hazard ratio 1.06, p = 0.0023), and to the likelihood of being among the 8 treatment failures at week 24 (AUC = 72.8%). Xpert Ct was even more strongly associated with culture conversion on the day the test was performed with AUCs 96.7%, 99.2%, 86.0% and 90.2%, at Day 7, Week 4, 8 and 24, respectively. Compared to baseline Ct measures alone, a combined measure of baseline Ct plus either Delta Ct or percent closing improved the classification of treatment failure status to a 75% sensitivity and 88.9% specificity. Conclusions Genome loads measured by Xpert provide a potentially-useful biomarker for classifying same day culture status and predicting response to therapy. PMID:27508390

    Full Text Available To help identify an epidemiological link between the consumption of buffalo mozzarella prepared with raw milk (not heat-treated and cases of human brucellosis, 80 samples of raw buffalo milk and 315 samples of mozzarella were tested for the presence of Brucella spp. Samples originated from Caserta, the province with the highest number of Brucella-positive buffalo herds in Campania, the region in which 96.02% of all cases of human brucellosis reported in 2000-2005 were recorded. To take into account possible seasonal variations, between February 2006 and March 2007, samples were purchased directly from 72 dairy outlets that were representative of the province. Samples were tested for Brucella spp. using the polymerase chain reaction (PCR and bacterial isolation. Samples tested negative for Brucella using both methods. Spiked samples were then prepared and tested by PCR and bacterial isolation and the sensitivity, specificity, repeatability, reproducibility and limit of detection were determined. The PCR limit of detection was below 1 colony-forming unit (cfu/g. The repeatability and reproducibility of the method were 100% (p = 0.95, the sensitivity was 96.7% (p = 0.95 and the specificity was 100% (p = 0.95.

    An ever-growing need exists for rapid, quantitative and meaningful methods to quantify and characterize the effect of different treatment steps on the microbiological processes and events that occur during drinking water treatment and distribution. Here we compared cultivation-independent flow cytometry (FCM) and adenosine tri-phosphate (ATP) analysis with conventional cultivation-based microbiological methods, on water samples from two full-scale treatment and distribution systems. The two systems consist of nearly identical treatment trains, but their raw water quality and pre-treatment differed significantly. All of the drinking water treatment processes affected the microbiological content of the water considerably, but once treated, the finished water remained remarkably stable throughout the distribution system. Both the FCM and ATP data were able to describe the microbiology of the systems accurately, providing meaningful process data when combined with other parameters such as dissolved organic carbon analysis. Importantly, the results highlighted a complimentary value of the two independent methods: while similar trends were mostly observed, variations in ATP-per-cell values between water samples were adequately explained by differences in the FCM fingerprints of the samples. This work demonstrates the value of alternative microbial methods for process/system control, optimization and routine monitoring of the general microbial quality of water during treatment and distribution.

    Two Brucella abortus S19 commercial vaccine strains used for vaccination against brucellosis in India and three S19 strains available as international reference were examined by microbiological assays and molecular analysis of the ery loci involved in erythritol metabolism, and tested for residual virulence in BALB/c mice. According to the sensitivity to penicillin and i-erythritol, the five strains tested had the phenotypic characteristics of strain S19. However, on culture medium containing i-erythritol, all strains developed spontaneous i-erythritol resistant colonies at mutation rates ranging from 1.42x10(-2) to 1.33x10(-6). The S19 characteristic 702 bp deletion in the erythrulose 1-phosphate dehydrogenase gene of the ery locus was present only in the three reference strains but not in the two commercial vaccines. Both commercial strains and one of the reference strains showed reduced virulence in BALB/c mice. The presence or absence in S19 strains of the 702 bp deletion in the ery locus had no correlation with either the rates of spontaneous mutation to erythritol resistance or the residual virulence in mice.

    Full Text Available In this study the effects of a new antibiotic combination, i.e., gentamycin, tylosin and linco-spectin (STLS on post-thaw motion characteristics, plasma membrane integrity, sperm morphology and the total aerobic bacterial counts (TABC in buffalo and Sahiwal bull semen were investigated. Ten ejaculates, five each from a buffalo and a Sahiwal bull, possessing more than 60% sperm motility were used. These ejaculates were diluted in Tris-citric acid (TCA extender (at 37 °C; 50 X 106 spermatozoa/mi, containing either GTLS (gentamycin 500 g/ml, tylosin 100 g/ml and linco-spectin 300/600 g/ml, streptomycin 1000 g/ml and penicillin 1000 IU/ml (SP, or negative control with no antibiotics (NCON. Samples were cooled to 4°C in 2 hours, equilibrated at 4°C for 4 hours, filled in 0.5 ml straws, frozen in a controlled rate cell freezer and plunged into liquid nitrogen. Frozen semen was thawed at 37°C for 15 seconds. Post-thaw sperm motion characteristics, plasma membrane integrity and sperm morphology were determined. Total aerobic bacterial counts and the frequency of appearance of bacterial genera were determined in neat semen, after dilution, and after freezing and thawing. Mean motilities (visual; computer-assisted, linear and circular, velocities (straight-line, average path and curvilinear and lateral head displacement (LHD in post- thaw semen samples did not differ due to antibiotics or species. Same was true for sperm plasma membrane integrity. Morphologically abnormal spermatozoa were lower (P<0.05 in GTLS and SP than in NCON. Sperm cells possessing normal acrosomes were higher (P<0.01 in GTLS and SP than in NCON. Total aerobic bacterial counts in post-thaw samples were lower (P<0.05 in GTLS than in SP or NCON. Staphylococcus and micrococcus were lower in samples treated with GTLS than that of SP or NCON. Pseudomonas and E.coli were more frequent in buffaloes than Sahiwal bull samples. Proteus and corynebacteria were scarcely present. In conclusion, GTLS was not determintal to post thaw motion characteristics, sperm morphology and membrane integrity of buffalo and Sahiwal bull spermatozoa. Furthermore, it efficiently reduced the number of aerobic micro-organisms in buffalo and Sahiwal bull semen.

  5. Retrospective study of the evolution of nutritional, inflammatory and bacteriological profiles of patients suffering from inoperable aero-digestive duct tumour during sequential or concomitant chemo-radiotherapy

    International Nuclear Information System (INIS)

    The authors report a retrospective study which aimed at analysing a cohort of consecutive patients in terms of clinic and biological aspects reflecting their nutritional and inflammatory status as well as the status of their buccal bacterial flora during a sequential or concomitant chemo-radiotherapy. The objective was to detect a possible difference between these both therapeutic modalities, and a possible relationship with toxicity. Several data have been collected for patients suffering from inoperable aero-digestive tract tumour: weight, body mass index, prealbumin, albumin, orosomucoid, C-reactive protein, PINI index, and buccal bacterial flora. The evolution of these nutritional biological criteria appears to depend on the treatment modality. Short communication

  6. A BACTERIOLOGICAL STUDY AMONG PATIENTS BELOW FIVE YEARS OF AGE SUFFERING FROM DIARRHOEA AND GASTROENTERITIS WITH SPECIAL REFERENCE TO THE RESPONSIBLE SEROTYPES OF ESCHERICHIA COLI AT A TERTIARY HEALTHCARE HOSPITAL IN EASTERN BIHAR

    Full Text Available INTRODUCTION: Diarrhoea is defined as passage of loose, liquid or watery stools. In the developing countries, diarrhoea remains a wet season disease with bacteria playing a greater role. The agents responsible for infantile diarrhoea may be bacteria, viruses, parasites, malnutrition and drugs. Infectious agents that cause diarrhoeal disease are usually spread by the fecal-oral route. Escherichia coli (E. coli is a gram-negative bacillus that may be found in the normal intestinal flora of humans and animals, but can also be an important cause of enteric illness. Our present study is an attempt to fulfil this vacuum and investigate the most common pathogens causing these diseases amongst patients in and around a tertiary care hospital of eastern Bihar, with special reference to the serotypes of Escherichia coli. MATERIAL AND METHODS: Samples were collected from both male and female patients below five years of age, admitted to the Pediatrics Department, with complains of diarrhoea and gastroenteritis. Samples were processed, identified and antibiotic sensitivity was done as per standard protocol. Serotyping of E. coli isolates was carried out using antisera as per manufacturer’s instructions. RESULTS: Different diarrhoeagenic strains of E. coli showed that the maximum numbers of strains were EPEC, followed by DAEC. EAEC and ETEC accounted for only a small percentage of strains. Upon Serotyping the different E. coli isolates from patients with diarrhoea, the results showed that the Serotype O26, O111 and O55 were the predominant serotypes of EPEC. Among the ETEC strains only 2 serotypes were seen viz. O6 and O15. Serotype O44 and O125 were the only two serotypes of EAEC seen. Among the DAEC, the only serotype was O1. The antibiotic susceptibility pattern of various isolates shows maximum resistance against ampicillin followed by cefixime. Strains were significantly sensitive to amikacin, gentamicin and ofloxacin. CONCLUSION: Our result shows high rate of diarrhoeagenic E. coli among Indian children presenting with diarrhoea particularly in Katihar / Kosi region of Bihar. The finding of diverse E. coli subtypes even amongst the small number of E. coli isolates highlights the importance of pathogenic E. coli in cases of diarrhoea and gastroenteritis and stresses upon the need for enhanced surveillance of children with diarrhoea in these parts of the globe.

    Danish farmers can order a real-time PCR mastitis diagnostic test on routinely taken cow-level samples from milk recordings. Validation of its performance in comparison to conventional mastitis diagnostics under field conditions is essential for efficient control of intramammary infections (IMI) with Staphylococcus aureus (S. aureus). Therefore, the objective of this study was to estimate the sensitivity (Se) and specificity (Sp) of real-time PCR, bacterial culture (BC) and California mastitis test (CMT) for the diagnosis of the naturally occurring IMI with S. aureus in routinely collected milk samples using latent class analysis (LCA) to avoid the assumption of a perfect reference test. Using systematic random sampling, a total of 609 lactating dairy cows were selected from 6 dairy herds with bulk tank milk PCR cycle threshold (Ct) value ≤39 for S. aureus. At routine milk recordings, automatically obtained cow-level (composite) milk samples were analyzed by PCR and at the same milking, 2436 quarter milk samples were collected aseptically for BC and CMT. Results showed that 140 cows (23%) were positive for S. aureus IMI by BC while 170 cows (28%) were positive by PCR. Estimates of Se and Sp for PCR were higher than test estimates of BC and CMT. SeCMT was higher than SeBC however, SpBC was higher than SpCMT. SePCR was 91%, while SeBC was 53%, and SeCMT was 61%. SpPCR was 99%, while SpBC was 89%, and SpCMT was 65%. In conclusion, PCR has a higher performance than the conventional diagnostic tests (BC and CMT) suggesting its usefulness as a routine test for accurate diagnosis of S. aureus IMI from dairy cows at routine milk recordings. The use of LCA provided estimates of the test characteristics for two currently diagnostic tests (BC, CMT) and a novel technique (real-time PCR) for diagnosing S. aureus IMI under field conditions at routine milk recordings in Denmark.

    Following the Louisiana landfalls of Katrina on August 29 and Rita on September 24, 2005, the local population and the American public were concerned about the effects the hurricanes might have on water quality in Lake Pontchartrain. The lake is a major recreational resource for the region and an important fishery. Contamination carried by the storm surge—along with runoff and water pumped from flooded areas of New Orleans—was considered a serious threat to the water body. The USGS, in collaboration with the LDEQ, monitored the sanitary quality of water at 22 sites in and around Lake Pontchartrain, La., for 3 consecutive weeks from September 13 to 29, 2005 (fig. 1). A subsequent multipleagency survey of 30 sites within Lake Pontchartrain was undertaken by the U.S. Environmental Protection Agency (EPA), the USGS, and the National Oceanic and Atmospheric Administration during the week of October 11–14, 2005, to evaluate the effects of the hurricanes and overall levels of fecal contamination on the water quality of the lake (see Heitmuller and Perez, this volume). In addition, the EPA monitored fecal-indicator concentrations at a variety of sites in New Orleans, surrounding areas, and the Mississippi River between September 3 and October 22, 2005 (U.S. Environmental Protection Agency, 2006). This article describes fecal-indicator bacteria concentration results collected by USGS in the context of other existing data.

This study was conducted to analyze the quality of drinking water available in most of the cities of Pakistan including earthquake hit areas. For this purpose, 112 water samples were collected and analyzed by membrane filtration method. Microbial isolates were identified using QTS-10 and biochemical tests. Almost all samples were found to be contaminated but in earthquake affected areas quality of drinking water was substandard than other areas of Pakistan. Results revealed the detection of following bacterial pathogens among the water samples: Enterobacter sp., Klebsiellasp., Stenotrophomonas sp., Salmonella sp., Proteus sp., Edwardsiella tarda, Pseudomonas aeruginosa, Vibrio parahaemolyticus, Vibrio cholerae, Escherichia coli, Acinetobacter baumanii, Aeromonas hydrophila, Citrobacter freundii, Shigella dysenteriae, Staphylococcus aureus, Staphylococcus sp. and Streptococcus sp. Furthermore, these bacterial isolates were found to be resistant to ampicillin (32.1%, amoxicillin (30.4%, sulphometoxazole (20.5% and cefaclor (31.3%. All drinking water samples were analyzed for 16S rRNA gene of Helicobacter pylori by using PCR, however no positive result was found in these samples. Based on our results it is suggested that authorities should pay attention to supply safe water and proper sanitary facilities to avoid epidemics of infectious diseases in future.

    The objective of this research was to evaluate the effect of packaging in 100% air and vacuum, combined with radiation (2 kGy and 3 kGy, on chicken breast fillet shelf-life by evaluation of bacterial deteriorants growth and pH variation parameters. The vacuum packaging increased shelf-life, when compared to commercial packaging in 100% air, both in non-irradiated and irradiated to 3 kGy fillets. The irradiation increased the shelf-life of fillet samples at both doses. The lactic acid bacteria were the organisms that most developed in irradiated samples, showing greater radioresistance, as compared to other microorganisms studied, while the enterobacteria showed greater sensitivity to treatment with ionizing radiation. The vacuum packaging, combined with irradiation, can be used to improve the safety of chicken breast fillets and to extend its shelf-life.

    KEY-WORDS: Deterioration; chicken meat; vacuum packaging; meat radiation.

    O objetivo deste experimento foi avaliar o efeito do uso de embalagens, em 100% ar e a vácuo, combinadas com a radiação gama (2 kGy e 3 kGy, no aumento do prazo de validade comercial de filé de peito de frango resfriado, avaliando-se os parâmetros de desenvolvimento de bactérias deteriorantes e a variação do pH das amostras. A embalagem a vácuo aumentou o prazo de validade comercial, quando comparada à embalagem em 100% ar, tanto nos filés não irradiados, como nos irradiados a 3 kGy. A irradiação das amostras, nas duas doses utilizadas, aumentou, consideravelmente, a validade comercial desse alimento. As bactérias láticas foram os micro-organismos que mais se desenvolveram nas amostras irradiadas, confirmando, assim, uma maior radiorresistência, quando comparada com os outros micro-organismos estudados, enquanto as enterobactérias demonstraram maior sensibilidade ao tratamento com radiação ionizante. A embalagem a vácuo, combinada com a tecnologia de irradiação, pode ser utilizada para melhorar a segurança de filés de peito de frango resfriados e para estender seu prazo de validade comercial.

    The authors report a retrospective study which aimed at analysing a cohort of consecutive patients in terms of clinic and biological aspects reflecting their nutritional and inflammatory status as well as the status of their buccal bacterial flora during a sequential or concomitant chemo-radiotherapy. The objective was to detect a possible difference between these both therapeutic modalities, and a possible relationship with toxicity. Several data have been collected for patients suffering from inoperable aero-digestive tract tumour: weight, body mass index, prealbumin, albumin, orosomucoid, C-reactive protein, PINI index, and buccal bacterial flora. The evolution of these nutritional biological criteria appears to depend on the treatment modality. Short communication

    One century ago, Christiaan Eijkman was appointed Professor of Bacteriology at the Utrecht University, The Netherlands. Despite his appointment to teach bacteriology, Christiaan Eijkman made his main contribution to medical science not in bacteriology but in nutrition. He discovered that Beri-Beri was not an infection but a nutritient deficiency (later called vitamin-deficiency) and was awarded the Nobel Prize for Medicine in 1929 for these observations. These landmark studies were made in the former Dutch East Indies. Interestingly, the results of his studies were presented in the Dutch language, in the medical journal of the Dutch East Indies. As a professor of Bacteriology, his work was the beginning of an important school in biochemistry in The Netherlands. PMID:10427404

    Bacteriological isolation of Yersinia pestis is the reference test for confirming plague infection, but recovery of the pathogen from human samples is usually very poor. When the etiology of the disease cannot be bacteriologically confirmed, it may be useful to possess alternative tests such as detection of specific circulating antibodies to help guide the diagnosis. In the present study, the immunoglobulin G (IgG) anti-F1 enzyme-linked immunosorbent assay (ELISA) has been applied to various ...

    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...

    2000-01-01

    The clinical and bacteriological efficacy of a 3-day course of pivmecillinam, 200 mg three times daily, was compared with that of a 7-day course of cephalexin, 250 mg four times daily, in 216 patients with a bacteriologically confirmed, acute, uncomplicated, urinary tract infection. Both treatments were similarly effective. Clinical cure or improvement was obtained in 95.3% of patients given pivmecillinam and in 93.6% of patients given cephalexin. Bacteriological success was achieved in 89.7 and 81.7% patients taking pivmecillinam or cephalexin, respectively. Eradication rates for Escherichia coli were 90.1% for pivmecillinam and 80.6% for cephalexin. Both treatments were well tolerated. This study has confirmed that a 3-day course of pivmecillinam is effective and well tolerated in uncomplicated cystitis. PMID:10724022

    In a multi-centre study in general practice, 292 female patients with acute urinary tract infection received a 5-day course of pivmecillinam at a dosage of either 200 mg or 400 mg twice-daily. Positive bacteriological cultures were obtained from 64 (31%) of 206 patients for whom bacteriological data was complete, and bacteriological cures were obtained in all 38 patients in the lower dose group and 22 (85%) of the 26 patients in the higher dose group. An equally good clinical response was seen with both treatments and the mean symptom score (maximum possible 15) was reduced from 7.46 to 0.73. Side-effects were reported for 7 (4%) patients in the lower dose group and 11 (10%) patients in the higher dose group. Two patients in each group ceased treatment due to nausea, which was the most frequently reported complaint. PMID:6504945

    Full Text Available To investigate the effect of dinoprost to the exclusion of the purulent exudate, the change of intrauterine bacteria and the reproductive performance in cows with pyometra, 13 Holstein cows with pyometra were treated with tromethamine dinoprost intramuscularly (25 mg as dinoprost one time on the day when pyometra was diagnosed. Then intrauterine perfusion fluid was collected for bacteriological examination at 3 days and 21 days after dinoprost treatment. In all cows estrus was induced by the dinoprost treatment within four days and the purulent material in the uterus was excreted from the uterus. Although Trueperella pyogenes was isolated in 12 cows out of 13 cows at the first bacteriological examination, it was isolated in only two cows at the second bacteriological examination. Seven out of 10 cows which received artificial insemination became pregnant after the dinoprost treatment. In conclusion, the dinoprost treatment is effective to not only exclude the purulent exudate but also eliminate T. pyogenes from uterus

    International Nuclear Information System (INIS)

    Ground beef packaged in polyethylene film was irradiated at different dose levels ranging from 0.25 to 1.0 Mrad and stored at 3+-10C. Bacteriological and organoleptic evaluations were carried out immediately after irradiation and at weekly intervals thereafter. The red color of the meat was darker after irradiation and this darkening increased with radiation dose. This color change was limited to the surface of the samples. The results of the bacteriological and organoleptic examination indicate that irradiation at 0.25 Mrad permits refrigerated storage of ground beef for 3 weeks, 0,5 Mrad for 6 weeks. Coliforms were found only in non-irradiated samples

  14. Effect of electron irradiation in hatching eggs experimentally inoculated with salmonella enteriditis, on hatch ability and broiler performance

    International Nuclear Information System (INIS)

    The effect of four doses of electrons irradaition on bacteriologic population in hatching egg following experimental shell contamination with Salmonella enteriditis phage type 13 was investigated. Fresh, whole, intact raw eggs were inoculated with 109 Colony-Forming Units of Salmonella enteriditis, eggs were irradiated with a beam electron source at either: 0.5, 1, 2 and 3 KGy. The bacteriologic evaluation was made with Gentry's and Williams' technic. After the irradiation the groups were taken to commercial hatchery and were incubated in satndards conditions. The bacteriologic evaluation of the shell showed a significant 2.8 log reduction on the group of eggs that were irradiated with 1 KGy as compared with 0.5 KGy doses group and control group (P<0.05). A negative correlation (r=-0.93) between irradiation doses and CFU (P<0.05) was also observed. Bacteriologic evaluation of the internal shell membrane exhibited a highly significant inactivation (P<0.01) of S. enteriditis of 100% in the group of eggs irradiated at 2 and 3 kGy. A high negative correlation (r=-0.90) between irradiation doses and samples of internal structures (P<0.05) was observed. The results obtained suggested that the electrons irradiation may be use like a control system of salmonelosis on egg and like desinfection system on hatching eggs because it did not cause any effect on hatchability and broiler performance.

    2012-04-01

    To evaluate the clinical and bacteriological efficacy of pivmecillinam against lower urinary tract infection (UTI) caused by extended-spectrum β-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae, patients treated for lower UTI with pivmecillinam (n=8) were studied. Patients treated with nitrofurantoin (n=3) and trimethoprim (n=3) or a combination of these agents with pivmecillinam (n=3) were included as a control group. Antimicrobial susceptibility was determined with EUCAST methodology. Bacteriologic cure was defined as pivmecillinam had good clinical response (8/8), but bacteriological cure rates were low (2/8). However, none of the patients with persisting bacteriuria had a relapse of UTI symptoms within 6 months. All isolates were susceptible to the given antimicrobial. Most isolates belonged to the CTX-M-1 group (n=11, 65%) or CTX-M-9-group (n=4, 24%). Four E. coli isolates belonged to the international clone O25b-ST131 (25%). In conclusion, pivmecillinam had good clinical activity against lower UTI caused by ESBL-producing Enterobacteriaceae, but bacteriological cure rates were low. The persistent bacteriuria appears to be of little clinical importance, but larger clinical studies are needed to determine the usefulness of pivmecillinam in infections caused by ESBL-producing bacteria.

  15. Quality control of meat using proton-transfer-reaction-mass-spectrometry (PTR-MS)

    International Nuclear Information System (INIS)

    Full text: Numerous food scandals which happened during the last few years make food safety controls more and more important. The method currently used for determining the status of meat, with respect to spoilage, is analysis of the counts of total viable bacteria and/or specific spoilage bacteria. An obvious drawback of this bacteriological method is the long incubation period of 1-3 days that is required for colony formation. Therefore we develop a novel method for meat quality control using PTR-MS which does not have this drawback. We measured the emitted volatile organic compounds (VOCs) of meat (beef and pork) using PTR-MS as a function of storage time. At the same time a bacteriological examination of these meat samples was carried out. We found strong correlations (about 99 %) between some VOCs and bacteriological contamination. This is a first step to replace the time-consuming bacteriological method by fast headspace air measurements to facilitate the investigation of a huge number of pieces of meat in very short time and to determine the maximum storage time and storage temperature from the emissions. We will also use this method to investigate the growth of various bacteria, the changes in the microbial composition and the influence of various environmental conditions such as temperature, pH, chemical and microbial preservation techniques.

  4. Diagnosis of tuberculosis in the wild boar (Sus scrofa: a comparison of methods applicable to hunter-harvested animals.

    Directory of Open Access Journals (Sweden)

    Nuno Santos

    Full Text Available BACKGROUND: To obtain robust epidemiological information regarding tuberculosis (TB in wildlife species, appropriate diagnostic methods need to be used. Wild boar (Sus scrofa recently emerged as a major maintenance host for TB in some European countries. Nevertheless, no data is available to evaluate TB post-mortem diagnostic methods in hunter-harvested wild boar. METHODOLOGY/PRINCIPAL FINDINGS: Six different diagnostic methods for TB were evaluated in parallel in 167 hunter-harvested wild boar. Compared to bacteriological culture, estimates of sensitivity of histopathology was 77.8%, gross pathology 72.2%, PCR for the MPB70 gene 66.7%, detection of acid-fast bacilli (AFB in tissue contact smears 55.6% and in histopathology slides 16.7% (estimated specificity was 96.7%, 100%, 100%, 94.4% and 100%, respectively. Combining gross pathology with stained smears in parallel increased estimated sensitivity to 94.4% (94.4% specificity. Four probable bacteriological culture false-negative animals were identified by Discriminant Function Analysis. Recalculating the parameters considering these animals as infected generated estimated values for sensitivity of bacteriology and histopathology of 81.8%, gross pathology 72.7%, PCR for the MPB70 gene 63.6%, detection of AFB in tissue contact smears 54.5% and in histopathology slides 13.6% (estimated specificity was 100% for gross pathology, PCR, bacteriology and detection of AFB in histopathology slides, 96.7% for histopathology and 94.4% for stained smears. CONCLUSIONS/SIGNIFICANCE: These results show that surveys for TB in wild boar based exclusively on gross pathology considerably underestimate prevalence, while combination of tests in parallel much improves sensitivity and negative predictive values. This finding should thus be considered when planning future surveys and game meat inspection schemes. Although bacteriological culture is the reference test for TB diagnosis, it can generate false

  5. Pivmecillinam in the treatment of urinary tract infections.

    Science.gov (United States)

    Nicolle, L E

    2000-09-01

    The efficacy of pivmecillinam for empirical treatment of acute uncomplicated urinary tract infection (UTI) was initially reported in clinical trials published in the 1970s and 1980s. Bacteriological cure rates observed in these trials were consistently >85%, and studies of different dosing regimens suggested that a 3 day course was appropriate. Comparative studies reported that pivmecillinam was equivalent to other antimicrobial agents in terms of clinical and bacteriological outcomes. These studies also documented that pivmecillinam was effective for treatment of Staphylococcus saprophyticus infections, was acceptable for use in pregnancy and was well tolerated. Subsequent widespread use of pivmecillinam in Scandinavian countries has led to a body of clinical experience which confirms the efficacy and safety of this antimicrobial agent in the treatment of acute cystitis. Recently, two large, prospective, randomized, double-blind, multi-centre clinical trials have been completed to assist in defining the role of this antimicrobial agent in the treatment of acute cystitis. A comparison of 3 day courses of pivmecillinam or norfloxacin, both at 400 mg bd, showed higher bacteriological cure rates with norfloxacin but generally similar clinical outcomes. A second, dose-ranging study found that pivmecillinam, given bd for 7 days, led to superior bacteriological and clinical outcomes at short-term follow-up than the 3 day regimen. Pooling bacteriological outcomes from the two studies showed similar outcomes with 7 days of pivmecillinam 200 mg bd or 3 days of norfloxacin 400 mg bd. The shorter, 3 day, course achieved similar short-term clinical outcomes to 7 days of pivmecillinam and 3 days of norfloxacin in women aged pivmecillinam is effective and well tolerated for the treatment of acute cystitis in women.

    Mastitis due to intramammary infections is one of the most detrimental diseases in dairy sheep farming, representing a major cause of reduced milk productions and quality losses. In particular, subclinical mastitis presents significant detection and control problems, and the availability of tools enabling its timely, sensitive, and specific detection is therefore crucial. We have previously demonstrated that cathelicidins, small proteins implicated in the innate immune defense of the host, are specifically released in milk of mastitic animals by both epithelial cells and neutrophils. Here, we describe the development of an ELISA for milk cathelicidin and assess its value against somatic cell counts (SCC) and bacteriological culture for detection of ewe mastitis. Evaluation of the cathelicidin ELISA was carried out on 705 half-udder milk samples from 3 sheep flocks enrolled in a project for improvement of mammary health. Cathelicidin was detected in 35.3% of milk samples (249/705), and its amount increased with rising SCC values. The cathelicidin-negative (n=456) and cathelicidin-positive (n=249) sample groups showed a clear separation in relation to SCC, with median values of 149,500 and 3,300,000 cells/mL, respectively. Upon bacteriological culture, 20.6% (145/705) of the milk samples showed microbial growth, with coagulase-negative staphylococci being by far the most frequent finding. A significant proportion of all bacteriologically positive milk samples were positive for cathelicidin (110/145, 75.9%). Given the lack of a reliable gold standard for defining the true disease status, sensitivity (Se) and specificity (Sp) of the cathelicidin ELISA were assessed by latent class analysis against 2 SCC thresholds and against bacteriological culture results. At an SCC threshold of 500,000 cells/mL, Se and Sp were 92.3 and 92.3% for cathelicidin ELISA, 89.0 and 94.9% for SCC, and 39.4 and 93.6% for bacteriological culture, respectively. At an SCC threshold of 1

    Full Text Available Sixty raw milk samples collected from six selling points and one collection center, in Souk-Ahras region, were bacteriologically examined in order to get bacteriological quality as defined by ministerial decree of 24-01-1998 of Algerian Republic. The search is on SPC, fecal coliforms, fecal streptococcus, Staphylococcus aureus and clostridium. Results showed that 100% of samples have unsatisfactory quality. 76.67 % of samples show a contamination level above the criteria for two different parameters and 10% for three different parameters. The overrun is due primarily to fecal streptococcus and second to Staphylococcus aureus (100% and 81.67%, with an average count of 9.7×102 and 31 mo ml-1, respectively. These results indicate food poisoning risk associated with raw milk consumption, stressing the need to apply strict controls throughout the dairy industry, to respect of the cold chain and to establish the thermal treatment.

    A marine environmental research programme is in course of carrying out for some years in a definite coastal zone of the southern Tirrenian Sea in order to point out possible significant pollutions, identify their origin and study the appropriate preventive and protective measures. In the first stage of the programme the analysis of the actual water quality was done, by evaluation of several indicators (temperature, conductivity, pH, turbidity and suspended sediments, dissolved oxygen, chlorophyll a, nutrients concentration, bacteriological parameters) at three different distances from the shore: 50 m, 500 m and 1 mile. The analysis of the collected values shows that the actual water quality is on the whole quite satisfactory, except for some restricted areas in which a bacteriological pollution, due to high concentrations of coliforms and Streptococcus faecalis, has been pointed out.

    International Nuclear Information System (INIS)

    Sodium deoxycholate is used in a number of bacteriological media for the isolation and classification of gram-negative bacteria from food and the environment. Initial experiments to study the effect of deoxycholate on the growth parameters of Escherichia coli showed an increase in the lag time constant and generation time and a decrease in the growth rate constant total cell yield of this microorganisms. Cell fractionation studies indicated that sodium deoxycholate at levels used in bacteriological media interferes with the incorporation of [U-14C]glucose into the cold-trichloroacetic acid-soluble, ethanol-soluble, and trypsin-soluble cellular fractions of E. coli. Finally, sodium deoxycholate interfered with the flagellation and motility of Proteus mirabilis and E. coli. It would appear then that further improvement of the deoxycholate medium may be in order

    Full Text Available Canine mastitis occurs primarily during the postpartum period and may also occur during pseudopregnancy, as well as after early weaning of puppies. Clinical and bacteriological examinations of mammary secretion were performed in 17 bitches and results of the bacteriological examination of milk samples were evaluated. Staphylococcus intermedius (n=11 was the predominant isolate from the canine milk while the other microorganisms were Escherichia coli, Pseudomonas aeruginosa, S. aureus, Citrobacter freundii, S. epidermidis and S. hyicus. According to the antimicrobial susceptibility test results, isolates were found mostly to be sensitive to gentamycin, while cefixime was detected as the least effective antimicrobial agent. As we had limited number of dogs in our study, further studies on this subject will be helpful for the veterinarians working with pet animals. Because dogs and humans live very closely in urban life style zoonotic transmissibility of S. intermedius shall be of interest to examine further in the future.

    In a multi-centre general practice study, 183 females suffering from symptoms of acute urinary tract infection were randomly assigned to receive 400 mg pivmecillinam twice-daily for either 3 or 7 days. The clinical response was equally good in both treatment groups with a mean reduction in symptom scores of 88%. Positive pre-treatment bacteriological cultures were obtained from 48 (36%) of the 134 patients for whom data were complete. Bacteriological cure was achieved in all these patients except for 1 in the 3-day treatment group. Pivmecillinam was well tolerated, with side-effects reported by 7 (7%) patients in the 3-day group and 12 (13%) patients in the 7-day group. One patient in the 3-day group and 2 patients in the 7-day group stopped treatment prematurely due to side-effects. PMID:6499513

  1. Status of quality of drinking water provided to hospitals in the area of Rawalpindi

    International Nuclear Information System (INIS)

    We examined the quality of drinking water in hospitals by Microbiological and physiological analysis of water samples from 17 hospitals in the region of Rawalpindi, Pakistan, First sampling was done in March to May and repeated in June to August to study variations in the bacteriological content over the summer months. Contamination levels were determined by using Most Probable Number Method. Escherichia coli was the indicator organism for contamination. Fecal contamination was also determined by incubating the test samples in a water bath at 44 deg. C for 24 hours. Bacteriological analysis and identification showed the presence of Escherichia coli, Salmonella typhimurium and Klebsiella pneumoniae. It was observed that 52% of the samples were unfit for drinking during the first sampling group and 58% percent were unfit during the second sampling group, showing some increase in bacterial content. MPN values were seen to rise over the sampling period corresponding to a rise in temperature and pH. (author)

    In this work are presented the results of water quality of seven springs (San Antonio Enchisi, Las Fuentes, El Cerro, Pasteje, Los Reyes, Santa Cruz and Tiacaque) and two water wells (Jocotitlan No. 2 and La Providencia No. 35) which are used for human consumption and that are located surrounding area to Jocotitlan volcano, state of Mexico. It was determined the {sup 222} Rn concentration through liquid scintillation, the {sup 226} Ra by Gamma spectroscopy, the physical-chemical parameters (major elements) and bacteriological, using standardized methods. The minor elements and trace in solution were determined by Icp-Ms mass spectroscopy. The water quality was established in function of the standing standards. Therefore Las Fuentes, El Cerro, Santa Cruz, Tiacaque springs and the Jocotitlan No. 2 well, are drinkable water. So, Pasteje, Los Reyes, San Antonio Enchisi springs and the La Providencia No. 35 well are chemically drinkable but presenting bacteriological pollution. (Author)

    Fifty-one children aged 2-14 years with recurrent tonsillopharyngitis, presenting dysphagia, fever and lymphadenitis, with more than two similar episodes in the last three years and showing a beta-hemolytic group A streptococci in the pharyngeal smear, were studied. They underwent random treatment for ten days with phenoxymethylpenicillin (40-60 mg/kg/day) (n = 28) or amoxicillin-clavulanic acid (20-40 mg/kg/day) (n = 23) taken orally three times a day. Clinical and bacteriological tests were carried out at 10 days and 2, 6 and 12 months post-treatment. The clinical and bacteriological results showed the superiority of the amoxicillin-clavulanic acid treatment both in the short term (disappearance of symptoms) and in the long term (decrease in recurrence). These results support the idea that betalactamases produced by the pharyngeal flora play an important role in the failures of penicillin. PMID:10878510

    Tuberculosis (TB) is a global public health problem endemic to Morocco. While extrapulmonary TB uncommonly presents in osteoarticular anatomic locations, tarsal or metatarsal osteitis can occur when TB presents in the tarsal bones. Clinical symptoms are often insidious causing a delay in diagnosis that may lead to bone destruction. While diagnosis can be guided by X-ray imaging, bacteriologic and histologic examination of the tissue allows for pathogen isolation, identification of the bacillu...

    Inflammatory diseases in childhood are quite different from those occurring in adults. The reasons are the special physiological, anatomical and immunological factors at the different stages of development. The different diagnostic possibilities (nasal swabs for virological and bacteriological examinations, X-ray, sonography, CT, endoscopy of the nose and paranasal sinuses) are discussed and the principles of the conservative and surgical therapy were demonstrated.
