Intestinal parasitism in eastern Gabon

: A survey of 1,548 stools samples carried out in Gabon showed in the adult population a parasitism ratio of about 100%. Among the protozoa, D. fragilis was found in 0.3% of the cases. In contradiction with the usual observations in tropical Africa, A. lumbricoides and T. trichiura infestation is very high in the villages. The demonstration of S. intercalatum in almost every place of the survey and an important focus at Okondja proves the extension of this bilharziosis.
