Introduction: Mupirocin, an inhibitor of bacterial isoleucyl-tRNA synthetase, has used to treat staphylococcal skin infections as well as to eliminate nasal carriage of Staphylococcus aureus. Mupirocin resistant Staphylococcus aureus strains are seen worldwide but there is no report from Iran. In the present study, by using phenotyping methods (disk diffusion and E-test) in combination with P...
BACKGROUND Shigella sonnei is considered as a major cause of diarrheal disease in both developing and developed countries. Iran is one of the endemic areas of shigellosis. The present study was undertaken to investigate the antibiotic susceptibility and genetic relatedness of S. sonnei strains isolated from pediatric patients in Tehran, Iran. METHODS The study included all S. sonnei strains i...
the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
OBJECTIVE The objective of the study was to investigate the prevalence of vancomycin-resistant Staphylococcus aureus (VRSA). MATERIALS AND METHODS Three hundred and fifty-six S. aureus isolates from the Imam Khomeini hospital in Tehran, Iran, were evaluated for methicillin and decreased vancomycin susceptibility by the microbroth dilution method. The mecA, vanAand vanB genes were targeted by ...
conclusions the emergence of streptococcus pneumoniae strains with multiple resistance needs permanent monitoring of antibiotic susceptibility patterns of clinical isolates. we have found that ceftazidime is not a suitable drug for choosing the treatment of pneumococcal infections. results the study showed that three strains (6%) and six strains (12%) indicated intermediate resistance and compl...
background and objectives: the pathogenic strains of escherichia coli cause severe septicemia, urinary tract infection and wound sepsis. resistance of this organism to the expanded-spectrum cephalosporins occurs via the production of extended-spectrum β-lactamases (esbls) such as tem and shv. these enzymes hydrolyze oxyimino cephalosporins (cefotaxime, ceftazidime) and monobactams (aztreonam). ...
background: in this study, erythromycin resistance isolates from the students with aged 12-15 yr old were studied and the mutations in the 23s rrna were identified by sequencing. methods: throat samples of 327 students with 12-15 years old from 3 schools of tehran were cultured on the selective streptococcus pyogenes medium and 23 strains were primarily selected as s. pyogenes . results: all ...
BACKGROUND The development of antibiotic resistance among Streptococcus pneumoniae strains has caused significant health problems worldwide. OBJECTIVES The aim of this study was to determine antibiotic resistance pattern and serotypes distribution of Streptococcus pneumoniae strains isolated from clinical specimens. MATERIAL AND METHODS A total of fifty Streptococcus pneumoniae strains were...
