Abstract Background The aim of this study was to compare the performance new flow cytometer UF-5000 with UF-1000i and Gram staining for determining bacterial patterns in urine samples. Methods Women who attended our clinic symptoms suggestive urinary tract infection were enrolled study. Mid-stream samples collected gram staining, analysis cultures. Bacterial classified using (none, cocci bacter...

The activities of OPT-80 against 453 intestinal bacteria were compared with those of seven other drugs. OPT-80 showed good activity against most clostridia, staphylococci, and enterococci, but streptococci, aerobic and facultative gram-negative rods, anaerobic gram-negative rods, and Clostridium ramosum were resistant. Poor activity against anaerobic gram-negative rods may maintain colonization...

Objective. To examine whether Gram staining can influence the choice of antibiotic for the treatment of peritonsillar abscess. Methods. Between 2005 and 2009, a total of 57 cases of peritonsillar abscess were analyzed with regard to cultured bacteria and Gram staining. Results. Only aerobes were cultured in 16% of cases, and only anaerobes were cultured in 51% of cases. Mixed growth of aerobes ...

The association between Gram negative enteric rods and Porphyromonas gingivalis in periodontal diseases has received little attention in the literature. Thus, the aim of this study was to investigate the associations between Gram negative enteric rods, Porphyromonas gingivalis and clinical parameters of periodontal disease. The prevalence of Gram-negative enteric rods and P. gingivalis were exa...

Bacterial vaginosis is the most prevalent disease of the female genital tract. In spite of various effective antibiotics in the treatment of bacterial vaginosis, its high relapse rate is a common problem. Bacterial species causing bacterial vaginosis are generally unable to be cultured by conventional methods. It is impractical and inadequate to use culture methods to guide initial treatment. G...

Introduction: Nosocomial infections are responsible for the much of the morbidity and mortality found in hospitals. The present study was conducted on 70 bacterial strains isolated from hospitalized patients in various medical units of Baqiyatallah Hospital in Tehran, Iran during a period of 12 months from; March to February 2009. Methods: The bacterial s...

The frequency of, risk factors for, and outcome of polyclonal gram-negative bacteremia are still unknown. We investigated them in a prospective cohort study of patients for whom a blood culture yielded >/=1 species of gram-negative aerobic rod. For each patient, pulsed field gel electrophoresis (PFGE) was performed on 4 colonies of each morphologic type. Episodes of bacteremia were considered p...

The diversity of bacterial isolates from soil in response to different plants (control, Brachiaria ruziziensis and Cajanus cajan), fertilization (control, simple superphosphate and rock phosphate) and liming (with and without lime) was evaluated. Phenotypic and physiological characteristics of the isolates were recorded and organized in a file to identify the bacteria. Among the isolates, 95% w...
