Epidemiologic studies of Escherichia coli diarrheal infections in a low socioeconomic level peri-urban community in Santiago, Chile.
The incidence of diarrhea due to six categories of diarrheogenic Escherichia coli was determined in two pediatric cohorts in a low socioeconomic level community in Santiago, Chile, with access to chlorinated water.
An age cross-sectional cohort of 340 children aged birth to 47 months was assembled.
A newborn cohort was assembled by enrolling 10-12 newborns monthly for 12 months.
Episodes of diarrhea were detected by twice weekly household visits.
E. coli from stool cultures of cases and matched controls were hybridized with DNA probes specific for enterotoxigenic, enteroinvasive, enteropathogenic, enterohemorrhagic, enteroaggregative, and diffuse adherence E. coli.
Overall, the incidence of diarrhea was low (2.1 episodes/infant/year).
