RESUMEN

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 ß-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.
