Abstract
The role of enteropathogenic Escherichia coli (EPEC) was evaluated in a group of children with endemic diarrhea admitted to Dhaka Shishu Hospital in Dacca, Bangladesh. EPEC was detected in fecal samples of 23% of 104 cases and 8% of 74 concurrent control children. The most commonly isolated EPEC strains were serogroups O20a, O20c:K61; O20a, O20b:K84; O26:K60; and O18a, O18c:K77. Except for O26:K60, these groups had not been reported from Bangladesh. On testing for enterotoxin production, only two strains (serogroups O26:K60, O18a, and O18c:K77) were enterotoxigenic. None was enteroinvasive as tested in the guinea pig conjunctivitis model. Our study supports the concept that EPEC may be an important cause of endemic diarrhea in Bangladesh.
