The nucleotide sequences of five plasmids from one Klebsiella oxytoca isolate were determined using the PacBio RS II system. Plasmid analysis revealed that bla(NDM-1) was carried on an IncX3 plasmid. The bla(IMP-4) and bla(KPC-2) genes were located on IncN and IncP-6 plasmids, respectively. Comparative sequence analysis highlighted the successful spread of carbapenemase-harboring plasmids among different enterobacterial species. We report for the first time, to our knowledge, coproducing NDM-1, KPC-2, and IMP-4 carbapenemases on a K. oxytoca isolate.
