[Evaluation of the prevalence of the main enteropathogenic agents in the West Imerina region: Manarintsoa].

For a 288 children's population aged from 5 to 14 years old and being school attendents in the village of MANARINTSOA, we have systematically investigated 60% of them in May 1988 and January 1989. Bacterial, parasitical and viral study of these stools showed off an important number of A. dispar and E. coli strains which have special phenotypes characters. The prevalence of Campylobacter and Ascaris lumbricoïdes is higher in this rural zone than in TANANARIVE. Two poliovirus of type 2 have been isolated in January 1989.
