Genetic features of CTX-M-15-producing Acinetobacter baumannii from Haiti

Abstract

Acinetobacter baumannii isolates T23, W35, and H1 were isolated from three patients who had been injured in the Haiti earthquake in January 2010. Those isolates, corresponding to two distinct clones, were identified as extended-spectrum β-lactamase (ESBL) producers and found to be bla CTX-M-15-positive. That ESBL gene was associated with ISEcp1, involved in its acquisition by a one-ended transposition mechanism. In all isolates, the ISEcp1-bla CTX-M-15 compound transposon was apparently chromosomally located. Copyright © 2011, American Society for Microbiology. All Rights Reserved.
