Increasing trend of antibiotic resistance and expression of Extended Spectrum Beta Lactamases (ESBLs) are se-rious threats for public health as they render the treatment ineffective. Present study was designed to elucidate the antibiotic-susceptibility patterns of ESBL and non-ESBL producing E. coli and K. pneumoniae causing uri-nary tract infections so that the ineffective antibiotics could be removed from the line of treatment. The bacterial isolates obtained from the urine of patients visiting a tertiary health care facility were cultured for strain identifi-cation using API20E. Antimicrobial susceptibility and ESBL detection were done by Kirby-bauer diffusion technique. Almost 53.4 % isolates of E. coli and 24.5 % isolates of K. pneumoniae were found to be ESBL pro-ducers. The ESBL producing bacteria were found to be more resistant towards various antibiotics. The most ef-fective drugs against E. coli ESBL isolates were imipenem (99.54 %), ampicillin-sulbactam (97.48 %), piperac...
