Results
70% of the acute pyelonephritis strains (table) were classified serologically with only five K antigens, numbers 1, 2, 3, 12, and 13. There were significantly more K-typable strains from patients with pyelonephritis (70%) than from those with
cystitis (53%) or asymptomatic bacteriuria (42%) or from faeces of healthy children (55%). Kl was the most frequent K antigen in all groups. Two of the K antigens, Kl and K12, were found more often in strains causing pyelonephritis (pyelonephritis compared with cystitis for Kl, p
