bla(IMP-4) in different genetic contexts in Enterobacteriaceae isolates from Australia

Antimicrob Agents Chemother. 2008 Aug;52(8):2984-7. doi: 10.1128/AAC.01634-07. Epub 2008 May 19.

Abstract

The IMP-4 metallo-beta-lactamase, originally recognized in Acinetobacter spp. from Hong Kong, more recently appeared simultaneously in isolates of the family Enterobacteriaceae from Sydney and Melbourne, Australia. The bla(IMP-4)-qacG2-aacA4-catB3 cassette array was found in isolates from both cities, but in different wider genetic contexts and on different plasmids, suggesting movement of this array by homologous recombination.
