Abstract
The hemagglutination patterns of 255 urinary E. coli isolates were examined with human (A, Rh+), bovine, chicken and guinea pig erythrocytes in the presence and absence of D-mannose. The strains were divided into 4 groups according to their hemagglutination properties. About 40% of the isolates agglutinated human red blood cells in the presence of D-mannose. The hemagglutinin of one of these, E. coli O18a, c:K- strain No. 119 was stable, temperature sensitive, did not develop at 18.degree. C and could be isolated by the methods used for the production of fimbriae. EM showed fimbriae on the surface of strain No. 119. An absorbed serum prepared from a derivative cured of hemagglutinating property (No. 119/1) agglutinated all the strains hemagglutinating human erythrocytes in the presence of mannose, but none of those having other hemagglutination patterns. Serologically, the antigen of No. 119 is independent of the K88, K99, 987 and CF I factors and shows some relationship to CF II.
