The study aimed to record the prevalence of Urinary Tract Infection caused by E. coli, its antibiotic sensitivity and phenotypic detection of ESBL and MBL producer E. coli. Total of 240 urine samples were collected from Bacha Khan medical complex, Swabi. Antibiotic sensitivity and production of ESBL and MBL according to CLSI guidelines 2017 were performed. Out of 75 E. coli strains, only 25 (33.3%) isolates were positive for ESBL. Similarly, 25 were resistant to Imipenem, in which 12 (16%) isolates were positive for MBL production. E. coli isolates were found more sensitive to Amikacin 57 (76%) followed by Imipenem 50 (66.67%), Ofloxacin 48 (64%), Ciprofloxacin 44 (58.67%), Norfloxacin 42 (56%) and were 100% resistant to Penicillin, Ceftriaxone, Ceftazidime and Cefotaxime. The current study recorded the prevalence rate of UTI caused by E. coli was 75( 66.96%) and ccurrence rate of ESBL and MBL producers in the total (n=75) E. coli isolates was 25( 33.3%) and 12(48%) respectively.
