Abstract: This study was done to evaluate the frequency of extended spectrum Beta-lactamase (ESBLs) producing uropathogens and their susceptibility pattern isolated from urine in Abubakar Tafawa Balewa University Teaching Hospital (ATBUTH) Bauchi. A total of 373 urine samples from out-patients and hospitalized patients were studied. Samples were inoculated on Cystine Lactose Electolyte-deficient (CLED) agar, Blood agar and MacConckey agar. 165 isolates were obtained which were further identified by standard Microbiological methods. Antimicrobial Susceptibility pattern was studied by Kirby-Bauer’s disc diffusion method. Among the 165 uropathogens isolated from patients with UTI, the commonest isolate was E. coli (29.1%) followed by Klebsiella pneumonae (15.8%) with the least Citrobacter spp. 1(0.6%). The overall prevalence of UTI of this study is 44.0%. Extended spectrum beta lactamase (ESBL) was noted in 100 (77.0%). Among the ESβLs producers detected, E. coli recorded the highest occurrence rate of 46 (46.0%) followed by K. pneumoniae with 22(22.0%). Others were, K.oxytoca 15(15.0%), P. aeruginosa 4(4.0%). However, there was no evidence of ESβL production observed in the clinical isolates of P. vulgaris and Citrobacter spp. Multidrug resistance was found to be significantly (P
