Antimicrobial Susceptibility Patterns for Recent Clinical Isolates of Anaerobic Bacteria in South Korea

Abstract

We determined the antimicrobial susceptibilities of 255 clinical isolates of anaerobic bacteria collected in 2007 and 2008 at a tertiary-care hospital in South Korea. Piperacillin-tazobactam, cefoxitin, imipenem, and meropenem were highly active beta-lactam agents against most of the isolates tested. The rates of resistance of Bacteroides fragilis group organisms and anaerobic gram-positive cocci to moxifloxacin were 11 to 18% and 0 to 27%, respectively.
