Present paper deals with 72 strains of E. coli isolated from urin of the urinary infected patients. Biochemical and serological characteristics and hemolytic activity of the strains were studied.
Results obtained were follows :
(1) 60 strains (83% of the isolated strains) were included in the known serological typing O1-to O134. O2, O3 and O25 types were dominately found, that is 4, 6 and 8 strains.
(2) 4 strains, identiffed to O75 type, were seemed to be causative organism of not only infantile gastroenteritis but urinary infections.
(3) K-antigen and hemolytic activity were observed in 15 strains (21%), but 1 strain, having K-antigen, did not show the hemolytic activity.
(4) On the biochemical study, all strains were identified to E.coli.
