[Bacterial, viral and parasitic etiologies of acute infantile diarrhea in a rural Senegal].

: We have studied the incidence of parasites, viruses and bacteria associated with acute infantile diarrhea in rural Senegal. Among parasitoses, Cryptosporidium parvum (7.7%) is the most frequent, followed by Entamoeba histolytica (5.1%). The first bacteriological etiologic agent is Escherichia coli (20.9%). Rotavirus are also frequently isolated (14.7%). Prevalence of pathogens is higher: among children over 6 months and under two years old, among children either with mixed feeding or weaned, during the raining season, except for rotaviruses. Breast feeding seems to be a good protective factor against bacterial and parasitological infections but not against rotavirus contaminations.
