[Etiological agents of urinary tract infections in children treated at the Institute of Mother and Child].
BACKGROUND
Urinary tract is a common site of bacterial infections in children. The main etiological agents of infection are Gram negative bacteria from the Enterobacteriaceae in particular of intestinal origin. The uropathogenic strains may indicate resistance for many antibacterial drugs.


OBJECTIVE
The aim of this study was an analysis of urine samples from outpatient or hospitalized children treated at the Institute of Mother and Child in Warsaw, in the years 2006-2007. The frequency of individual bacterial species and antibiotic susceptibility were investigated.


METHODS
In all, 2096 urine samples from patients treated at the Institute of Mother and Child were investigated. Bacteriuria was examined and antibiotics susceptibility was estimated. Biochemical tests were used for the identification of uropathogenic strains. Antibiotic susceptibility was examined using standard diffusion discs methods.


RESULTS
During 2006-2007, in all 2096 urine samples were taken, of which 313 were positive (14.9%). E. coli was the most often isolated bacteria (54%) and enterococci dominated in Gram-positive bacteria.


CONCLUSIONS
Enterobacteriaceae were the most frequently isolated bacteria. Most of the antibiotics used in the treatment of urinary tract infections had high antibacterial activity except for ampicillin.
