其他摘要：Background Urinary tract infection (UTI), are the most frequent and serious infection in childhood around the world. The present study aimed to evaluate antibiotic sensitivity of urinary tract pathogens among children in Zahedan, South East Iran. Materials and Methods This cross-sectional study analyzed 396 patients aged 1-18 years with positive urine and suspected UTI. Gender and age of children, kind of isolated bacteria in urine culture, susceptibility and resistance of these bacteria to current antibiotics were studied. Bacterial growth for more than 105 CFU/ml was considered as positive. Data analyzed by SPSS version 21.0. Results The most common age of urinary tract infection were < 1 year and 1-7 years for boys and girls, respectively, and the variation of sex distribution was significant in different age groups (P = 0.003). The most prevalent cause of UTI was Escherichia coli(E.coli) (77%), in total ages and both gender, afterward was Enterobacter (8.1%) and Klebsiella (7.1%). E.coli sepsis was highly sensitive to nitrofurantoin (74.7%), ciprofloxacin (72.5%), and amikacin (64.6%), both highly resistant to trimethoprim and sulfametoxazole (74.8%), ampicillin (66.9%), and nalidixic acid(51.1%); and its resistance to ceftriaxone was increasing. Conclusion In this study resulted that E. coli was the first responsible pathogen in proven culture of UTI in children, which was increased in resistance to popular antibiotics like Ampicillin, Sulfamethoxazole-trimethoprimand Nalidixic acid. In several countries, emphasize the need for local population specific surveillance for guiding empirical therapy for UTI in children.
