PCR detection of blaIMP gene in Imipenem resistant E. coli is the aim ot this study. Total of n=66 of n=23 Imipenem resistant E. coli were selected for the present study based on the drug resistance pattern and their MIC to Imipenem. Phenotypic detection of MBL production was carried out and subsequently, PCR amplification of blaIMP was carried out. Among selected (n=23) Imipenem resistant E. coli (IREC), 100% (n=23) strains were positive for Imipenem mediated MBL production. Twenty-three MBL positive IREC isolates were shown presence of Plasmid DNA, with size measured about approx. 6kb. PCR amplification of blaIMP gene codes for Imipenem mediated MBL production yielded amplified blaIMP gene product with amplicon size of 189 bp. The presence blaIMP gene also contributes for MBL production which makes organisms to show reduced susceptibility against Imipenem antibiotic
