- Abstract
Antibiotic drug resistance in E. coli is a worldwide health problem. Particularly, increasingly reported carbapenem resistance due to carbapenemases is highly worrisome. Literature regarding incidence of class B metallo-β-lactamases (MBLs) - producing E. coli has not yet judiciously been addressed. In this study, we investigated the occurrence of carbapenemase- and MBLs-producers among a collection of 100 carbapenem resistant E. coli obtained from a tertiary hospital at Lahore Pakistan. All carbapenemase producers were further investigated to identify frequency of blaIMP and blaVIM encoding genes. Results of modified hodge test identified 81% carbapenemase producers, while combined disc diffusion test identified 28 isolates as MBL producers among them. Of all carbapenemase producers, 25 isolates (30.8%) of carbapenemase-producing E. coli were found to harbor bla-VIM gene, while 13 isolates (16.04%) were found to carry blaIMP gene. We report on high incidence rate of carbapenemase producers among carbapenem resistant E. coli isolates.
