Etiology and antimicrobial susceptibility pattern of pathogenic bacteria in children subjected to UTI: A referral hospital-based study in northwest of Iran
MetadataShow full item record
Urinary tract infection (UTI) is 1 of the most common bacterial diseases in children with a considerable resistance to antimicrobials. This 5 years prospective study was carried out to determine the frequency of isolation and antimicrobial resistance patterns of uropathogens among children subjected to urine culture at Tabriz Children Educational-Health Care Center, in the northwest of Iran. Organisms were isolated using standard culture techniques. Frequency of UTI among children examined by urine culture was 3.6%. The isolated bacteria were Escherichia coli (71.4%), followed by Klebsiella spp. (9.6%), Enterococcus spp. (6.4%), Pseudomonas aeruginosa (4.2%), Serratia spp. (4.2%), and Enterobacter spp. (4.2%). E coli resistance levels were 11% for nitrofurantoin, 15% for ciprofloxacin, 25% for nalidixic acid, and 30% to 75% for amikacin, gentamicin, ceftriaxone, ceftizoxime, cefotaxime, and co-trimoxazole. Among the tested antibiotics, ciprofloxacin, showed the highest activity (100%) against Klebsiella and P aeruginosa isolates followed by amikacin, nalidixic acid, and gentamicin. Overall, the highly active antibiotic against Gram-negative and Gram-positive organisms was amikacin and then ciprofloxacin. On the other hand, the empirical initial therapy with co-trimoxazole and third-generation cephalosporins would be inadequate for more cases of UTI in the study area. Moreover, susceptibility testing should be carried out on all clinical isolates, and the empirical antibiotic treatment changed accordingly. Copyright é 2015 Wolters Kluwer Health, Inc.
