Abstract

Accurately identifying carbapenem resistant enterobacteriace (CRE) from fomites is critical for infection control practices, research, and assessing patient risk. We compared a commercial CRE agar intended for patient use with a modified MacConkey agar. We found that our modified MacConkey agar was more selective at identifying CRE from environmental sources.

Keywords: Drug resistant gram negative organisms; Environmental contamination; Microbiology methods; Screening agar.
