The objective of this study is to evaluate the diversity and abundance of the forms of dissemination of helminths and protozoa present in the waters of wadi Bouishak (Meknes, Morocco), and to elucidate the risks that these parasites present for health. The wastewater sampling has carried out monthly during a period from January to December 2017 between 10 am and 11 am at the three stations (B1, B2 and B3) that flow into the wadi. The 36 samples analyzed were positive with a predominance of protozoan cysts on Helminth eggs (29.08 105 cysts/L against 4573 eggs/L). Thirteen parasite taxa has detected: Giardia lamblia, Entamoeba histolytica, Entamoeba coli, Blastocystis hominis, Ascaris lumbricoides, Trichuris trichiura, Ancylostoma diudinal, Capillaria sp Toxocara canis, Enterobius vermicularis, Taenia saginata, Hymenolepis nana and Hymenolepis diminuta. The results obtained reveal a high parasite contamination of the watercourse, which could have negative effects on the quality of the environment in general and on human and animal health in particular.
