Abstract

The primary focus of this research is to analyze the appearance, characteristics, and relationship between antibiotics and E. coli bacteria isolated from urinary tract infections (UTIs). Conducted at Al-Muthanna Governorate Hospital and educational laboratories, 100 clinical samples were collected from the urine of UTI patients between March 5, 2024, and June 6, 2024, all under the supervision of a specialist physician. The antibiotic susceptibility test revealed that the E. coli bacteria were multi-drug resistant (MDR). All 50 isolates (100%) exhibited antibiotic resistance. Specifically, 47 isolates (94%) were resistant to erythromycin, 49 isolates (98%) to carbenicillin, 44 isolates (88%) to rifampin, 38 isolates (76%) to ceftazidime, 37 isolates (74%) to cefotaxime, 26 isolates (52%) to tetracycline, and 33 isolates (66%) to novobiocin.

Keywords: Phenotypic, Escherichia coli, sensitivity, antibiotics.
