Abstract

The spread of ESBL-producing bacteria through environmental compartments needs to be quantified to understand the drivers of resistant infections caused by ESBL bacteria, including the examination of water as a possible transmission pathway1. Effective methods to assess environmental contamination by ESBL-producing bacteria are critical to enable rapid and reliable testing in LMIC settings, and ideally, they should be simple, cost effective and utilize current infrastructure. We present findings from an adaption of an ESBL IDEXX Colilert system, developed by the Centers for Disease Control and Prevention (CDC)2, for the identification and quantification of ESBL contamination in four urban Malawian markets.
