Antibiotic resistance is observed in both pathogenic and normal commensal flora. Gastrointestinal tract may serve as a reservoir for carbapenem resistant Enterobacteriaceae (CRE), resulting in cross transmission within / among health care settings. Awareness of the fecal carriage of Extended spectrum Beta lactamase (ESBL) and Carbapenemase- Producing Enterobacteriaceae (CPE) bacteria is very important for the clinicians, microbiologists, infection control practitioners and epidemiologists. Forty rectal swabs were collected from the ICU patients were inoculated directly onto MacConkey agar containing 5mg/l Cefotaxime. The grown isolates were subjected to identification and antimicrobial susceptibility testing. The BioMerieux RAPIDEC CarbaNP test and Modified Carbapenemase inactivation method (mCIM) were performed to detect the Carbapenemase producing Enterobacteriaceae, as per CLSI guidelines. A total of 25 isolates were obtained from rectal swabs of 40 ICU patients. Of 25 isolates, 10 (38%) were E. coli and 15 (62%) were Klebsiella species. CarbaNP test showed positive for 7 isolates (70%) out of 10 E. coli and 13 isolates (41%) out of 15 Klebsiella species. The mCIM test showed positive for 8(80%) isolates out of 10 E. coli and 15(100%) isolates showed positive Klebsiella species. In CarbaNP test and mCIM, 5 and 2 isolates were negative respectively. mCIM is relatively simple and requires good technical skill compared to RAPIDECCarbaNP.
