Abstract :

Background: Intestinal parasites are found throughout the world and remain a neglected public health problem in the poorest communities. In Cameroon, children are the most vulnerable group and the environmental causes of such health issue remain questionable.

Objectif: The aim of this study was to assess the environmental risk of intestinal parasite infections in lowland areas of the city of Yaounde-Cameroon.

Methodolody: A cross-sectional survey was conducted from November to December 2016 to assess the environmental risk of intestinal parasite infections in lowland areas of the city of Yaounde-Cameroon. A total of 82 samples were collected in various aquatic environments including wells, rivers, and furrows associated with agricultural practices in Nkolondom, Nkolbisson, Tsinga. Physico-chemical parameters such as electrical conductivity and turbidity were measured using a multiparameter. However, soil samples were analyzed using two parasitological tests i.e. modified Kato Katz and Formaline-Ether methods.

Results:Physico-chemical parameters showed significant variations according to locations. An average of 4450±6404 FTU for the turbidity in the breeding sites of Nkolbisson shows that it presents the highest concentrations in organic matter.  Parasitological diagnostic allowed the identification of 14 parasite species. Entamoeba histolytica (233 kystes /L) and Strongyloides stercoralis (46 larvae) were the most abundant. Samples from wells presented the highest frequency of parasites (63.69%) at Tsinga and furrows of Nkolondom presented high frequencies of parasites. These localities had the highest frequencies with respectively (66.66%) for Diphyllobothrium latum and (50%) for Schistosoma mansoni.

Conclusion/Recommandation:This preliminary investigation indicated that the environmental risk of intestinal parasite infections is real and needs to be better addressed in order to prevent these diseases.
