Background: Antimicrobial resistance can vary significantly across different regions, making it crucial to understand the distribution of urinary pathogens and their susceptibility to antibiotics in specific settings. This knowledge is essential for guiding effective empirical treatment approaches. In Ethiopia, including Southern Ethiopia, there is a lack of recent data regarding the magnitude of the problem of antimicrobial resistance in urinary tract infections (UTIs). Due to limited microbiology laboratory capabilities, routine culture and antibiotic susceptibility testing are not performed in the region. This study aims to determine the most prevalent Uropathogen causing UTIs and their susceptibility to antimicrobial agents among individuals suspected of having UTIs in the study area.By conducting this study, we aim to provide valuable insights into the current situation of antimicrobial resistance in UTIs in Southern Ethiopia. -A cross-sectional study was carried out from April to September 2022 at Bule Hora University Teaching Hospital. The study included a total of 279 suspected patients who visited the outpatient department. Socio-demographic data and associated factors were assessed using a pre-tested questionnaire. Clean catch mid-stream specimens were collected following standard microbiological procedures. The identification of gram-negative organisms was done using TSI, Oxidase, H2S production, Gas production, Motility, Indole production, Urease production, Citrate utilization, and lysine decarboxylation and deamination. Antibiotic susceptibility testing of the isolates was conducted using the Kirby-Bauer disc-diffusion method.Data analysis was performed using SPSS version 25, and descriptive statistics were used to summarize the findings. The results were presented in words and tables. Binary logistic regression was used to determine the statistical association between predictors and outcome variables.Results: -A total of 279 individuals were participated in the study. The overall prevalence of gram negative Uropathogens were 11.8%. The predominant bacteria isolated was E.coli 57.7% followed by Klebsella species 9(27.3%), Proteus species 3(9.1%).Bacterial uropathogens, especially resistant strains of E. coli, pose a significant threat. Amoxicillin-clavulanic acid, trimethoprim-sulfamethazole, and ciprofloxacin were found to be ineffective against these strains. Regular surveillance of uropathogenic bacteria's sensitivity to antibiotics can help clinicians make better treatment choices. More research is needed on both gram-positive and gram-negative bacteria, focusing on the molecular characterization of resistant genes.
