Abstract

In a comparison of 3 agar plate methods, we found that a novel chromogenic medium, Remel Spectra™ CRE, had the best overall sensitivity (97.8%) when compared to the CHROMagar™ KPC (76.6%) and a direct ertapenem disk method (83.0%) for the detection of blaKPC-positive Enterobacteriaceae from perirectal swabs.

Keywords: CHROMagar; Chromogenic media; Klebsiella pneumoniae carbapenemase; Perirectal swabs; Screening; Spectra CRE.
