Abstract: Background: Most common cause of Urinary Tract Infection (UTI) is Escherichia coli. However, in past many years antibiotic resistance Escherichia coli has emerged. Material and Methods: This retrospective study was conducted in the Department of Microbiology in a tertiary care hospital over six months from June 2022 to December 2022. Total 214 urine samples were received to the microbiology department. To identify the possible Bacterial cause from suspected UTI male outdoor patient, from urine sample by culture and biochemical tests. The antibiotic sensitivity test was done on Mueller - Hinton agar by the Kirby - Bauer disc diffusion method. Results: Out of 214 urine samples, 130 (62.00%) yielded significant bacterial growth. Among them E. coli was the most predominant bacteria 62 (48%) followed by Citrobacter spp.19 (15 %), Pseudomonas 14 (10.15%) Proteus 10 (9.25%) different Gram - Positive bacteria 16 (12%) and Acinetobacter 9 (5.63%). All (100%) E. coli were sensitive to imipenem and colistin sulphate and 50% resistant to ciprofloxacin and 100% resistant to Ampicillin. Conclusion: it can be said that antibiotic resistance against commonly using antibiotics is an alarming sign for health care system to treat the outdoor patients for common disease.
