The somatic (O) and capsular (K) antigens ofEscherichiacoli from the urine of patients with acute pyelonephritis, acute cystitis, and asymptomatic bacteriuria, and in the fæces of healthy schoolchildren have been investigated. Typing antisera for sixteen capsular acidic polysaccharide K antigens were used, and five (numbers 1, 2, 3, 12, and 13) accounted for 70% of isolates from patients with acute pyelonephritis. These five K antigens were found to a lesser extent in the three other study groups. Thus, only a few K polysaccharides are associated with virulent properties ofE. colifor the upper urinary tract. This finding is similar to the association of only some capsular types of pneumococci, meningococci, andHœmophilus influenzœwith invasiveness. The identification of virulence markers forE. coliassociated with upper-urinary-tract disease may permit more successful control with reference to preventive immunisation.
