Indistinguishable NDM-producing Escherichia coli isolated from recreational waters, sewage, and a clinical specimen in Ireland, 2016 to 2017

Euro Surveill. 2017 Apr 13;22(15):30513. doi: 10.2807/1560-7917.ES.2017.22.15.30513.

Abstract

In this study, New Delhi metallo-beta-lactamase (NDM)-producing Enterobacteriaceae were identified in Irish recreational waters and sewage. Indistinguishable NDM-producing Escherichia coli by pulsed-field gel electrophoresis were isolated from sewage, a fresh water stream and a human source. NDM-producing Klebsiella pneumoniae isolated from sewage and seawater in the same area were closely related to each other and to a human isolate. This raises concerns regarding the potential for sewage discharges to contribute to the spread of carbapenemase-producing Enterobacteriaceae.

Keywords: New Delhi metallo-beta-lactamase; antimicrobial resistance; carbapenemase-producing Enterobacteriaceae; recreational waters; wastewater.
