Abstract: Among imipenem-nonsusceptible isolates, acquired metallo-beta-lactamase genes were detected in 36 of 581 (6.2%) Pseudomonas aeruginosa isolates, 42 of 44 (95.4%) other Pseudomonas species, and 136 of 513 (26.5%) Acinetobacter species from 2003 to 2004 at a Korean hospital. Overall, bla(VIM-2)-like genes were the most prevalent and were also detected in Enterobacteriaceae, including Klebsiella pneumoniae.
