Evaluation de l’efficacité des désinfectants sur la viabilité des formes de résistance des helminthes intestinaux isolés des eaux usées et des boues de vidange à Yaoundé

Abstract

Helminthiasis is a major public health problem nowaday, negatively affecting the socio-economic development and causing high death rates. These parasitic infections particularly affect tropical regions of the world, and one of the factors that favor dissemination and contamination of people is the resistance of environmental forms in aquatic environments. These parasites are thought to be highly resistant to the techniques commonly used for water treatment, and their presence in wastewater is the real constraint on wastewater reuse. In order to limit the contraction of intestinal helminthiasis, it is essential to optimize the techniques used for water treatment. Optically the study carries out is to highlight the efficiency of ten disinfectants (Calcium Chloride, Sodium Hypochlorite, Hydrogen Peroxide, Gypsum, Moringa, Activated Carbon, Sodium Chloride, Light Rays, "Hand Disinfectant", and Moringa combined with Calcium Chloride) on the viability of helminth resistance forms, it was conducted in microcosm at the Laboratory of Hydrobiology and Environment of the University of Yaoundé I.
