[Bacterial flora in urinary tract infections of children and susceptibility to drugs].

The material consisted of 902 strains isolated from children with urinary tract infection with significant bacteriuria. Among isolated strains, Enterobacteriaceae consisted 67.4%, Gram-positive cocci 18.8% and non-fermenting Gram-negative bacilli (both against Gram-negative bacilli and Gram-positive cocci), appeared aminoglycosides and III generation cephalosporins (from 63 to 83% of susceptible strains). K. pneumoniae and P. aeruginosa were most resistant to antimicrobials tested. The authors point out that empiric antibiotic therapy of bacterial urinary tract infections in children which is not preceded by identification of the pathogen and determination of its drug susceptibility, can be ineffective in over 50% of cases.
