Dissemination of New Delhi metallo-β-lactamase-1-producing Acinetobacter baumannii in Europe

摘要: Multidrug-resistant and New Delhi metallo-β-lactamase 1 (NDM-1) -producing Acinetobacter baumannii are increasingly reported. A collection of five NDM-1-positive A. isolates recovered in four European countries were analysed. Genotyping was performed by pulsed-field gel electrophoresis, multiplex PCR sequence typing, Diversilab multilocus typing. Three distinct types identified. All harboured a chromosomally located bla(NDM-1) gene within Tn125-like transposon. One isolate co-expressed another unrelated carbapenemase OXA-23. This report constitutes the first epidemiological study NDM-1-producing from countries.
