[Epidemiological studies, with the direct and immunodiagnostic method, of parasitic diseases in residents of a Somalia village located in the irrigated zones].

The authors carried out an epidemiological survey for the evaluation of the incidence of the parasitoses in a Somali village localized in proximity to a watercourse. They found parasites in the 72,53% of the examined population: Schistosoma haematobium 42.5%, Ascaris lumbricoides 32%, Ancylostoma duodenale 14%, Entamoeba histolytica 7,5%. The immunofluorescence, nevertheless, showed the presence of antiparasite antibodies in a much higher percentages of cases; it could meant that the real incidence of the various parasitoses is greater than it appears with direct examination.
