Abstract

Urinary tract infection (UTI), is defined as a disease caused by invasion of urinary tract by microorganisms. Majority of UTI cases are due to bacterial infection constitute about 95% of total UTI cases. About 80% of UTI cases are caused by E.coli producing extended spectrum ?-lactamase (ESBL) producing isolates. In recent years limitations in treating infections caused by multidrug resistant organisms has increased. This study aims to determine ESBL production of E. coli cases from a tertiary care hospital. Methodology: A total 358 midstream urine samples were collected by random sampling method during March 2015 to June 2018. Identification, antibiotic sensitivity testing, performed according to standard protocol following Clinical and Laboratory Standard Institute (CLSI) guidelines, 2013. Screening for ESBL producing E.coli isolates performed using ceftazidime further confirmation done by phenotypic disc diffusion test using combined disc method using ceftazidime (30µg) & ceftazidime/ clavulanic acid (30/10 µg) as per CLSI guidelines. Results: Total 358 specimens processed for urine culture. Gram negative bacilli isolated from 123(34.35 %), out of which 68 (55.28%) were E.coli, 19 (15.44%) K. pneumoniae, 15 (12.19%), Pseudomonas spp. 08 (6.50%), Citrobacter spp and Acinetobacter spp, 03 (2.43%), Proteus mirabilis, 01 (0.81%) Proteus vulgaris and Enterobacter respectively. Out of 68 isolates of E.coli, 65 (95.58%) were MDR, ESBL was detected in 31 (47.69%) out of these 65 isolates. Out of these 31 cases 19 (61.29%) were female and 12 (38.70%) were male cases. Conclusion: This study concludes 47.69% ESBL producing MDR E. coli were isolated from UTI cases with female predominance.
