Online published on 2 March, 2017. Abstract Widespread spread of CTX-M type extended-spectrum beta-lactamases (ESBL) in E. coli strains which are resistant to extended-spectrum cephalosporins is the most remarkable example for rapid and global spread of plasmid mediated antimicrobial resistance in bacteria. The incessant spread and global prevalence of ESBL resistance poses a serious threat to the human health, as it is responsible for the narrowing of therapeutic options pertaining to infections. A sum of 20 uropathogenic isolates of E. coli were subjected for the antibiotic susceptibility pattern using different antibiotics and followed by the detection of blaCTX-M gene by PCR. By which, we found increased percentage of isolates were resistant to different antibiotics and 30% of them were having this gene. This indicates the prevalence of such antibiotic resistance gene in our region. Proper antibiotic policies would promote the patients health condition better.
