High Rates of Nonsusceptibility to Ceftazidime-avibactam and Identification of New Delhi Metallo-β-lactamase Production in Enterobacteriaceae Bloodstream Infections at a Major Cancer Center

Clin Infect Dis. 2016 Oct 1;63(7):954-958. doi: 10.1093/cid/ciw398. Epub 2016 Jun 16.

Abstract

Resistance to the novel β-lactam/β-lactamase inhibitor combination ceftazidime-avibactam (CAZ-AVI) among carbapenem-resistant Enterobacteriaceae (CRE) has infrequently been reported in the United States. We report unexpectedly high rates of resistance to CAZ-AVI in CRE bloodstream isolates at our institution associated with the nonoutbreak spread of New Delhi metallo-β-lactamase in diverse Enterobacteriaceae species.

Keywords: CRE; NDM; bacteremia; carbapenemase; ceftazidime-avibactam.
