materials and methods one hundred ssis specimens were obtained by needle aspiration from purulent material in depth of infected site. these specimens were cultured and incubated in both aerobic and anaerobic condition. for detection of antibiotic susceptibility pattern in aerobic and anaerobic bacteria, we used disk diffusion, agar dilution, and e-test methods. results a total of 194 bacterial ...

the aim of this study was to assess the prevalence of esbl-producing e. coli in agricultural fields of gorgan district, golestan province. soil samples were collected from 20 agricultural fields, half of them treated with chemical fertilizers and the rest with bovine manure. two samples, from surface and a depth of 15cm, were taken. after enrichment and culture onto macconkey agar, pink colored...

conclusions only a few number of health workers do respect hygiene rules before and after catheterization. therefore, it is necessary to train health workers involved in such activities on good hygiene practices during catheterization. results two days later, (48 hours after the catheterization), 14 patients out of 60 (23.33%) presented with a urinary infection, of which 1 patient (1.66%) was a...

BACKGROUND Brucella is a group of bacteria that causes brucellosis, which can affect population health and reproductive success in many marine mammals. We investigated the serological prevalence of antibodies against Brucella bacteria in a declining harbor seal population in Glacier Bay National Park, Alaska. RESULTS Prevalence ranged from 16 to 74 percent for those tests detecting antibodies...

To determine the prevalence of indicator bacteria resistant to antimicrobials among poultry in three Southeast Asian countries (Vietnam, Indonesia and Thailand), we examined the antimicrobial susceptibilities of commensal bacteria isolated from chickens. In total, 125, 117 and 180 isolates of Escherichia coli, Enterococcus faecalis and Enterococcus faecium, respectively, were used to test for a...

BACKGROUND Prevalence and load of airway bacteria in stable and exacerbated chronic obstructive pulmonary disease (COPD) has been previously studied using microbiological culture. Molecular techniques, such as quantitative PCR (qPCR), may be more informative. METHODS In this study, 373 sputum samples from 134 COPD outpatients were assessed for prevalence and load of typical airway bacteria (H...
