DURING a 15 month surveillance conducted at an Atlanta hospital, Boris and co-workers1 reported that 31.7% of all diarrheas in children under 2 years of age were due to nine commonly recognized groups of enteropathogenic Escherichia coli, hereafter referred to in this paper as EEC. In the non-white population under 4 months of age hospitalized with acute gastroenteritis, EEC was found in 53%.

Because of the high incidence of gastroenteritis in this locality, much of which was of unknown cause, a study was conducted on the relative importance of certain other serogroups of E. coli reported to have been associated with outbreaks or with sporadic cases of gastroenteritis. The selection of the serogroups included in this study was based on information contained in the reports of Ewing and Davis2 and Ewing, et al3 on the occurrence of E. coli serotypes associated with diarrheal disease.
