The emergence of carbapenemase-producing Enterobacteriaceae is a rapidly evolving threat worldwide. Here, we report the molecular characterization of two Klebsiella pneumoniae isolates carrying both bla(OXA -181) and bla(NDM -1) or bla(NDM -5) isolated from epidemiologically unrelated patients in Singapore. The bla(OXA -181) genes were found existing in different genetic environments.
Keywords: Carbapenemases; Enterobacteriaceae; gram-negative resistance; metallo-β-lactamases; oxacillinases.
