Abstract
Results of the examination of urine specimens with evidence of acute urinary tract infections from children aged .ltoreq. 16 yr in general practice were analyzed over 16 mo. Infections were much more common in girls than in boys, with Escherichia coli most frequently involved in both groups. Urinary tract infections caused by Proteus strains were predominantly associated with boys. Infections in girls showed a higher incidence at 3, 6 and 16 yr of age. Possible reasons for these sex- and age-associated patterns of infection are discussed. An important factor in the prevention of urinary tract infections in young girls may be proper superivision of school lavatories. The usefulness of information obtained from the analysis of diagnostic results based on a simple but thorough laboratory approach was demonstrated.
