Introduction: Urinary tract infections are the second common infection in children, which cause renal parenchyma damage- as the most major sequel. This study aimed to investigate the prevalence of asymptomatic urinary tract infection (UTI) in primary school children of Hamadan City and drug resistance of isolated microorganisms in 2014.

Methods: In this descriptive/analytical cross-sectional study, 350 urine samples were collected from the students of Hamadan City using the two-stage cluster sampling. The samples with positive nitrate and pH above 7 were cultured. Then, they were inoculated on the blood agar and Mac Conkey agar and after 48 hours of incubation, positive culture samples with at least 105 CFU/ ml were identified using standard microbiological methods. The sensitivity of isolated pathogens to 12 common antibiotics for gram negative bacteria and 11 common antibiotics for gram positive ones using the standard agar disk diffusion method was evaluated. The results were analyzed using SPSS version 19 and chi-square test.

Results: The results showed that from 62 (17.7%) students suspected to UTI, 45 cases (12.8%) were diagnosed. The most common isolated microorganisms were Escherichia coli 16 (35.5%), Staphylococcus aureus 14 (31.1%), Staphylococcus saprophyticus 9 (20%) and Enterococcus spp. 6(13.3%), respectively. Also, it was found that E. coli was 100% sensitive to Nitrofurantoin. Regarding S. aureus and S. saprophyticus, amikacin was found to be the best antibiotic and ofloxacin for Enterococcus .

Conclusion: Considering the prevalence of UTI without obvious symptoms in children, especially girls of primary school age and the probability of recurrence or its complications, screening, diagnosis and treatment of UTI in students is important. Furthermore, the impact of factors in the prevention of urinary tract infection with education in schools is essential.
