Abstract: Urinary tract infections (UTIs) remain among the most prevalent bacterial infections worldwide, particularly in resource-limited settings where empirical treatment is commonly practiced. This study aimed to determine the prevalence and antimicrobial susceptibility of extended-spectrum beta-lactamase (ESBL)-producing Gram-negative bacilli among symptomatic UTI patients at Port Sudan Teaching Hospitals. A cross-sectional study was conducted between January 2023 and January 2024, involving 150 patients with UTI symptoms. Midstream urine samples were cultured and tested for antimicrobial resistance using the Kirby-Bauer disk diffusion method. Of the 150 samples, 71 (47.3%) were culture-positive, with Escherichia coli as the most common isolate (20%). High resistance was noted against Ceftazidime (70%) and Nalidixic acid (60%), while Amikacin (64.7%) and Nitrofurantoin (56.9%) exhibited higher sensitivity. ESBL activity was phenotypically confirmed in 8 out of 34 resistant isolates. These findings underscore the urgent need for regular surveillance and informed antibiotic prescribing to curb resistance in the region.
