Analysis of OXA23 and AmpCβ-Lactamase Genes in Clinically Isolated Multidrug-Resistant Acinetobacter baumannii Clonal Complex 92.

Multidrug-resistant Acinetobacter baumannii, which is resistant to carbapenems, amino glycosides, and fluoroquinolones, was isolated from the wound of an outpatient. We performed Multi Locus Sequence Typing and analyzed the structures of the AmpC β-lactamase and OXA23 carbapenemase genes. This strain was assigned as ST451, a member of clonal complex 92, by its MLST scheme.
