The importance of fecal colonization with P-fimbriated Escherichia coli for the later development of pyelonephritis was studied among infants before the age of 11 months. In contrast to previous studies, the fecal colonization with a P-fimbriated E. coli strain did not increase the incidence of acute pyelonephritis.
