Introduction: Urinary tract infection (UTI) is one of the most common causes of bacterial infection in the community and hospital. Urinary tract infection is more common in women than in men .The economic and public health costs resulting from urinary tract infection and the increasing antibiotic resistance are significant and have a large impact on the quality of life of infected patients .
Methods: In this descriptive-cross-sectional study, during a one-year period from April to March 2022, urine samples of outpatients and inpatients referred to khatam ol anbiya hospital in Shirvan were collected using the Clean Catch Midstem method. First, the samples were cultured on Mc Conkey agar and blood agar media, and incubated at 35-37°C for 24-48 hours. A colonization rate equal to or greater than 105 colonies per ml was considered as a positive sample. Then the morphology of the colonies is examined and standard biochemical tests are carried out in cluding: Urea, SIM, MR/VP, TSI and Simon Citrate, phenylalanine deaminase and warm dyeing were used.
Results: In this study, 1096 urine samples from outpatients and inpatients referred to the laboratory of khatam ol anbiya Shirvan Hospital, 119 urine cultures (10.85%) were positive 86 samples (72.27%) are women and 33 samples (27.73%) are men. The most common bacterial isolate is Escherichia coli with 52 (43.7%), Candida sp 29 (24.36%), Enterococcus 14(11.76%) Klebsiella species with 8 (6.73%%), Staphylococcus epidermidis 8 (6.73%), Pseudomonas aeruginosa 5 (4.20%), Non-Enterococcus 2 (1.68%), Staphylococcus aureus 1(0.84%) were isolated.
Conclusion: According to the obtained results, Escherichia coli bacteria is the most common cause of urinary infection, which is more than other isolates and is the most dominant bacteria in causing urinary infection. Candida sp is the second cause of infection, which has a significant difference compared to other Gram-negative and Gram-positive bacteria.
