Eighty one rectal swabs (RS) were cultured on CHROMagar KPC and the CDC method. Of the 81 samples, 9 were positive for KPC-producing Klebsiella pneumoniae on CHROMagar KPC, and 6 for the CDC method. CHROMagar KPC had two false positive (FP) results: 1 K. pneumoniae and 1 Acinetobacter sp. FP results on the CDC method were: 25 Acinetobacter spp., 2 Escherichia coli and 4 K. pneumoniae: CHROMagar KPC yielded a better recovery of KPC-producing bacteria and less FP results than CDC method. In order to evaluate FP results on CHROMagar KPC, 1247 RS were cultured and yielded 1021 negatives, 171 KPC-producing K. pneumoniae and 55 FP (4.4 %). Because of the FP results growing on CHROMagar KPC, KPC must be phenotypically confirmed in the bacteria isolated.
