Abstract

Carbapenem-resistant Acinetobacter spp. are being increasingly reported worldwide, including in South Korea, where we examined 144 representative isolates collected in a nationwide hospital survey in 2005. Metallo-β-lactamases were detected in only 19.4% of isolates, none of which were Acinetobacter baumannii, whereas 74.3% of isolates (mostly A. baumannii) expressed bla_OXA carbapenemase genes. Among the latter, 47 had bla_OXA-23-like genes and 56 had upregulated bla_OXA-51-like variants, including bla_OXA-66, _-83, _-109 and _-115; bla_OXA-115 was a novel variant, detected in two isolates. bla_OXA-72 (bla_OXA-40-like) was detected in only a single Acinetobacter baylyi isolate, whilst three Acinetobacter calcoaceticus isolates had both bla_VIM-2-like and bla_OXA-58 genes. Pulsed-field gel electrophoresis (PFGE) suggested the spread of A. baumannii clones with OXA carbapenemases within and between hospitals. In conclusion, the recent increase in imipenem-resistant Acinetobacter spp. from South Korea is mostly due to OXA-type carbapenemases.
