A Cursory Survey of the Intestinal Parasites of Natives Living in Southwest Sudan 1

Abstract

Summary Examination of fecal specimens from 79 natives living in a tropical region of the Sudan revealed that 67 per cent of the people were infected with Endamoeba histolytica (“small” and “large” races), one per cent with Dientamoeba fragilis, 5 per cent with Entermonas hominis, and there was one infection with Isospora. Eggs of Ancylostoma and Trichostronglyus were recorded in 3 per cent and 2 per cent, respectively, of stools examined. Ascaris was absent although conditions for its propagation seemed favorable. There was a single case of infection with Trichuris and one with Hymenolepis. Eggs of Schistosoma mansoni were detected in 10 per cent of the stools.
