this study investigated the antibacterial resistance among enterococci isolated in tehran hospitals. a total of 277 enterococcus faecalis, 123 enterococcus faecium and 13 isolates of other enterococcal strains were collected from 1 march 2002 to 15 april 2004 from three teaching hospitals of tehran university of medical sciences. the minimum inhibitory concentrations (mic) of tested antibiotics...

bacterial resistance to antibiotics is a serious problem and is increasing in prevalence world-wide at an alarming rate. the antimicrobial susceptibility patterns of 1897 gram-positive bacterial isolates were evaluated. the minimum inhibitory concentration (mic) of isolates which comprised staphylococcus aureus (927 isolates), coagulase-negative staphylococci (cns; 425 isolates), enterococcus f...

BACKGROUND In an era of increasing antimicrobial resistance, knowledge of local antimicrobial susceptibility patterns of common uropathogens is essential for prudent empiric therapy of community-acquired urinary tract infections. OBJECTIVES To define antimicrobial susceptibility of Gram-negative uropathogens in northern Israel over a 10 year period and to compare it with patterns of antibioti...

background acinetobacter calcoaceticus baumannii (acb) complex are gram-negative opportunistic bacteria with low virulence properties. their resistance to antibiotics has become a matter of concern in hospital infections. objectives the present study aimed to determine the prevalence and antimicrobial susceptibility of acb isolates collected from the nemazee hospital of shiraz. in addition, pul...

The serotype, Shiga toxin (Stx) type, and antimicrobial resistance patterns of 138 Stx-producing Escherichia coli (STEC) strains isolated from humans between 2003 and 2007 in Shizuoka Prefecture, Japan were characterized. The predominant O serogroups of the STEC isolates were O157, O26, and O111. Antimicrobial susceptibility testing of the STEC isolates showed that 31 of the 138 isolates (2...

conclusions due to the variable nature of antibiotic susceptibility patterns and etiological agents of septicemia, continual assessment of the most frequent pathogens associated with bloodstream infections and detection of their sensitivity patterns to locally available antibiotics seem to be reasonable measures. results from a total of 491 blood cultures, 74 (15.1%) samples were detected as po...

introduction: stenotrophomonas maltophilia is a nosocomial multi drug resistant opportunistic pathogen which causes infections in vulnerable patients with cancer, cystic fibrosis and indwelling catheters. methods: 45 clinical s. maltophilia isolates were collected from blood samples and identified by biochemical tests. susceptibility to different antibiotics including co-trimoxazole, levofloxac...
