Background: Bloodstream infection (BSI) is an important cause of mortality and morbidity and among the most common health-care associated infections. In this study we described the frequency of occurrence and antimicrobial susceptibility patterns of nosocomial and community-acquired BSI isolates from a teaching hospital in Tehran, Iran. Results: During the study period, 456 isolates were obtained from blood cultures, from a total of 8818 collected sets, among which 291were felt to represent true bacteremia and 98 were nosocomial. Acinetobacter spp. were the most Conclusion: We did not observe any vancomycin-resistant strains among isolates of S. aureus. Rifampin and ciprofloxacin showed good activity against most of gram-positive and gram-negative organisms, respectively. Carbapenems (imipenem and meropenem) were highly active against strains of Enterobacteriaceae (E. coli, Klebsiella) that showed resistance to third generation of cephalosporines.
