Bacterial Uropathogens Causing Urinary Tract Infection and Their Resistance Patterns Among Children in Turkey

Urinary tract infection (UTI) is a common problem in infants and children, as well as adults. The aim of this study was to assess the most common bacterial uropathogens, their susceptibility, and resistance to antibiotics in children with UTI. This study included 7,365 urine samples sent from various departments to the Kars state hospital microbiology laboratory between January 2012 and May 2014. Bacterial isolation from clinical samples was made using standard microbiological methods. Antibiotic susceptibilities were determined by disk diffusion, according to CLSI recommendations. Bacterial growth was obtained in 1,373 samples (18.5%). The percentage distributions of the isolates were as follows: Escherichia coli, 940 (68.5%); Proteus spp, 183 (13.3%); Staphylococcus spp, 85 (6.2%); Enterococcus spp, 65 (4.7%); Klebsiella, 62 (4.5%); Pseudomonas aeruginosa, 21 (1.5%); and other Gram-negative bacteria and Gram-positive bacteria, 17 (1.2%). UTIs were more prevalent, after two years of age, among females than males (P < 0.001). The identification of the most common microorganisms causing infectious diseases and regional resistance patterns is important in order to determine the antimicrobial policies and infection control guidelines of hospitals.
