Abstract

Increasing prevalence of carbapenem resistant Klebsiella pneumoniae is a global concern. Carbapenem resistant in Klebsiella pneumoniae can be mediated by carbapenemase production or by extended-spectrum beta-lactamase or AmpC beta-lactamase production. In this study, carbapenemase-encoding genes including blaKPC, blaNDM, blaOXA48, blaVIM, and blaIMP were detected in 187 carbapenemase producing Klebsiella pneumoniae by multiplex PCR. The most commonly encountered carbapenemase genes were blaKPC (58.3%), blaNDM (21.4%) and blaOXA-48-like (18.7%). The blaVIM and blaIMP genes were not detected in any of these isolates. 53 of the 187 isolates harboured multiple carbapenemase genes such as blaKPC+blaNDM, blaKPC+blaOXA48-like, blaNDM+blaOXA-48-like, and blaKPC+blaNDM+blaOXA-48-like. Most of these isolates were highly resistant to many commonly used antibiotics.
