OK serogroups of 408 strains of Escherichia coli isolated from diarrheal infants were determined by the use of the OK serogroups of enteropathogenic Escherichia coli (EEC). Of 408 strains of Escherichia coli tested, 8 strains (2.0%) were classified in to 3 OK groups. OK groups were isolated from 7 diarrheal infants (6.6%). These OK groups were 0128a, b:K67 (5 strains), 0126:K71(2 strains) and 044:K74(1 strain). All of 8 classical enteropathogenic strains of Escherichia coli were consistently negative in the suckling mouse. No strains were invasive when inoculated into the coitjunctival sac of guinea pigs.
