We studied the etiological structure of urinary tract infection (UTI) in 51 preterm infants and the etiology of asymptomatic bacteriuria in 60 preterm infants with body weight at birth from 780 g to 3000 g and gestational age from 27 to 37 weeks. Urine culture was carried out by Gould quantitative method from 3 to 6 times in the dynamics of observation. Most UTI pathogens are represented by gram negative microorganisms. Most often (48-50%) bacteria of the Enterobacteriaceae are found among them. Gram positive cocci (Staphylococcus spp., Enterococcus faecalis) were found in 3-27% of infants. Сandida spp. was found in 7-40% of infants. The etiology of UTIs in infants with a birth weight of less than 1500 g was characterized by a high frequency of bacterial and Candida spp associations. Asymptomatic bacteriuria was represented by the same spectrum of microorganisms as UTI pathogens.
