Enteric flora constitutes 95% of the cells in the human body. It has been shown that the bacterial content of this flora is affected by diet and changes in nutrition. Considering that urinary tract infections (UTI) are mostly due to ascending infections from the gut flora, the importance of the elements of this flora and their characteristics becomes more evident. The aim of this study was to evaluate the influence of oral Saccharomyces boulardii (S. boulardii) intake on the number of Escherichia coli (E. coli) colonies in the colon. This study was carried out with 14 boys and 10 girls (total of 24 children) aged between 36 and 192 months (mean: 104.3+/-45.1 months). A commercial capsule or powder containing 5 billion colony-forming units (cfu) of S. boulardii was administered once a day for 5 days. The number of E. coli and yeast colonies was measured in the stool samples of the study group before and after the use of this drug. Before treatment, the mean number of E. coli colonies in g/ml stool was 384,625+/-445,744. This number decreased significantly to 6,283+/-20,283 after treatment (p=0.00). S. boulardii was not detected in stool before treatment and the number of colonies increased to 11,047+/-26,754 in g/ml stool. S. boulardii may be effective in reducing the number of E. coli colonies in stool. The influence of this finding on clinical practice such as prevention of UTI needs to be clarified by further studies.
BACKGROUNDAlthough high antituberculosis (anti-TB) drug resistance rates have been reported in Turkey, the clinical characteristics and implications for the outcome of anti-TB treatment have not been fully investigated. We determined the prevalence of anti-TB drug resistance and examined demographic data, clinical characteristics and treatment outcome in relation to patterns of resistance.METHODSFrom the TB case registry of a university hospital and the two largest dispensaries in Manisa city, we identified all pulmonary TB cases with a culture-proven definitive diagnosis and antimicrobial susceptibility results for a 7-year period. We collected and analyzed demographic and clinical data and information on treatment outcome for those cases in relationship to anti-TB drug resistance.RESULTSOf 355 M. tuberculosis strains, 71.5% were susceptible to streptomycin, isoniazid, rifampicin and ethambutol. Any drug resistance and multi-drug resistance (MDR ) rates were 21.1% and 7.3% and were higher in males (53% and 9%, respectively) than in females (22% and 1%, respectively). Drug resistance was significantly higher in old cases (acquired drug resistance) vs new cases (primary drug resistance), and was associated with treatment failure (P<0.001). The prevalence of MDR was significantly higher in the old cases (22.4%) than in the new cases (4.4%) (P<0.001). Symptoms, radiographic findings, associated diseases, and sputum smear positivity were unrelated to the development of resistance. The prevalence of any drug resistance and MDR was significantly higher in those with treatment failure than in patients with treatment success.CONCLUSIONHigh resistance rates, particularly for acquired MDR, indicate a need for improvement in the TB control programme in our region.
Background:The aim of this study was to determine the prevalence of group B Streptococcus (GBS) colonization and to evaluate the antimicrobial resistance profile in women in the third trimester of pregnancy. Materials and Methods: A total of 310 pregnant women, referred in weeks 35 to 37 of gestation, were screened for GBS colonization during a 10-month period. Samples were collected from the vagina and the rectum. Results: The colonization rate was 10.6 % and 22 women (66.7%) had both positive vaginal and rectal cultures. Rates of GBS colonization were significantly lower in patients aged 24 years or older and in those with a third or later pregnancy. None of the isolates were resistant to penicillin and ampicillin, whereas 21.2% and 9.1% showed resistance to erythromycin and clindamycin, respectively. Conclusion: Screening and antimicrobial susceptibility testing of GBS during pregnancy are important to guide appropiate therapy.
In vitro, midazolam had an antimicrobial effect on E. coli, P. aeroginosa, A. baumannii and E. coli ESBL. Like propofol and dexmedetomidine, etomidate-lipuro had no antimicrobial effect on any of the micro-organisms tested.
Introduction: Circumcision is a historical operation which is still performed for different purposes. The aim of this study is to investigate the changes in periurethral and glanular sulcus flora due to circumcision to determine the role of circumcision on urinary tract infections (UTIs). Patients and Methods: Fifty patients who were circumcised for social-religious reasons between January 2000 and January 2001 were evaluated in this prospective study. Two swabs were taken from the periurethral and glanular sulcus regions both just before circumcision and 4 weeks after, and the bacteria cultured were recorded. Results: We isolated pathogenic bacteria in the periurethral region of 32 (64%) patients (enterococci in 14 cases; Escherichia coli in 12 cases) before circumcision, and this number decreased to 5 (10%) after circumcision. Similarly, pathogenic bacteria were cultured from the glanular sulcus swabs of 33 (68%) patients (enterococci in 14 cases; E. coli in 10 cases), as well as coagulase-negative staphylococci in another 15 patients before circumcision. Following circumcision, we detected pathogenic bacteria in the glanular cultures of only 4 cases, whereas 40 children had non-pathogenic skin flora. Only 1 of 5 children with history of UTIs (n = 1) and retractable phimosis (n = 4) had periurethral pathogenic bacteria (Proteus spp.) in the post-circumcision period. The differences between pre- and post-circumcision values of the pathogenic bacterial colonizations were statistically significant in both groups sampled (p < 0.05). Conclusion: Non-circumcised patients have similar pathogenic bacterial colonizations in the periurethral and the inner preputial regions, although they have no phimosis. The origin of periurethral flora should be the deeper preputial regions. The flora greatly changed with skin commensals after circumcision. Circumcision might be beneficial from this point of view.
