A multidrug-resistantAcinetobacter baumannii isolate recovered from a patient hospitalized in Switzerland after a transfer from Serbia produced the NDM-1 carbapenemase. Thebla NDM-1 gene was part of a chromosomally located Tn125 composite transposon bracketed by two copies of the same insertion sequence, ISAba125 . This transposon was also associated with the acquisition and expression of thebla NDM-2 gene in anA. baumannii isolate in Germany. Tn125 appears to be the main vehicle for dissemination ofbla NDM genes in that species.
