Complete Sequences of Two Plasmids in a blaNDM-1-Positive Klebsiella oxytoca Isolate from Taiwan

Genetic determinants of a blaNDM-1-positive, multidrug-resistant bacterial isolate that caused active infection was investigated by DNA sequencing. Two plasmids, pKOX_NDM1 and pKOX-R1, were identified for the Klebsiella oxytoca strain E718. Sequence annotation revealed a blaNDM-1 gene in pKOX_NDM1 and two extended-spectrum β-lactamase producers (blaCTX-M-3 and blaSHV-12) and a wide array of resistance genes in pKOX-R1. These findings highlight the difficulty in treating multidrug-resistant bacterial infections and the potential danger of emerging resistant enterobacteria.
