Background: Urinary tract infections (UTI) and their complications cause serious health problems this affects millions of people every year. Infections of the urinary tract are the second most common type of infection in the body and approximately 20 % of women are especially prone to UTIs for reasons not yet well understood. UTIs in men are not as common as in women but can be very serious when they do occur. Accurate identification of bacterial isolates is an essential task of the clinical microbiology laboratory. Objectives: The purpose of this study was to determine the incidence and variety of the causative microbial agents of UTIs in patients who were referred to a medical laboratory, Kashani and Hajar hospital in Shahrekord, Iran. Materials: In this cross-sectional study 147 urine samples of patients (urine test result was positive to UTIs) were examined during an April to September 2013. A total of 147 urine samples of patients with clinical symptoms of UTI who had been referred to medical laboratory, Kashani and Hajar hospital in Shahrekord, Iran were collected and processed immediately in the labora¬tory for analysis. Results: Escherichia coli was identified as the most common causative agent of UTIs (51.70% of total isolates in both sexes), followed by Klebsiella pneumoniae (K. Pneumoniae) (16.32%). Frequency of Proteus spp., Acinetobacter spp., Entrobacter spp., Citrobacter spp., Pseudomonas aeruginosa (P. aeruginosa) and Providencia spp. was 10.88%, 6.12%, 5.44%, 4.08%, 3.40% and 2.04%, respectively. Statistical analysis by Fisher exact test showed that there was no significant relationship between the type of bacteria and gender (P > 0.05). Chi square test that there was no significant relationship between the type of bacteria and the use of catheter and age group (P > 0.05). But there was a significant relationship between the type of bacteria and the history of hospitalization (P >0.05). Conclusions: Our findings implied a wide range of bacteria can be involved in creating urinary tract infection in patients referred to a medical laboratory, Kashani and Hajar hospital in Shahrekord, Iran. Regardless of age, sex and the use of catheter, a wide range of bacteria can be involved in creating urinary tract infection.
