The character and prevalence of the O, H, and combined O and H serotypes of E. coli from children with urinary tract infection are described. The data presented include 288 strains of E. coli isolated from 164 patients.

In addition the data from 28 patients with both an acute and a recurrent urinary tract infection are analyzed.

Eighty-five per cent of the recurrent infections were caused by an organism serologically at variance with that causing the initial infection. However, in approximately one-fourth of these there was some question whether the serologic difference represented a truly different strain. On this basis it would appear, contrary to earlier thinking, that most recurrences of infection represent reinfection with a new strain rather than relapse with an original strain.

The serologic characterization of strains of E. coli promises to aid materially our understanding of the natural history, epidemiology, and pathogenesis of pyelonephritis in infancy and childhood.
