Physico-Chemical Parameters of the Soil and Distribution of Forms of Resistance of Human Parasites in the Mbam and Inoubou Division (Bokito-Cameroon)

Abstract

This study was conducted to assess the physico-chemical parameters of soils and the distribution of resistance forms of soil-transmitted helminths and protozoa in the land surrounding the Okole and Lebomo streams in Bokito. The sedimentation and the Faust technics were used to identify and count the resistance forms of intestinal parasites. Among the 40 soil samples collected, 27 presented at least one parasite; for an overall contamination rate of 22%; thus distributed helminths (14%) and protozoa (8%). High values in parasite density were recorded during the short rainy season in Strongyloides stercoralis with a contamination frequency of 2, 1%. On the other hand, parasites such as Trichuris trichiura, Toxocara canis and Isospora belli were not observed during the short dry season. No significant spatio-temporal variation was observed for temperature, pH and dissolved oxygen. This result would be due to the absence of anthropogenic actions and the influence of environmental conditions.
