Abstract

Co-Production of NDM-1 and OXA-232 by<i>Klebsiella pneumoniae</i>

Highlights

  • Isolates producing New Delhi metallo-β-lactamase 1 (NDM-1) were first reported in the United States in 2010 (2), followed by several case reports and most recently a hospital outbreak in Colorado (3–6)

  • We report K. pneumoniae co-producing NDM-1 and OXA-232, a variant of OXA-48, and Escherichia coli producing NDM-1 that were isolated from the same patient

  • PCR and sequencing identified NDM-1 and OXA-232, a 5-aa variant of OXA-48 recently reported in K. pneumoniae isolates from India (9)
