title: [Parasitological analysis of the untreated wastewater of the "Ville Haute" urban emissary (Mâamora district, Kenitra, Morocco)].
abstract: The domestic wastewaters of the city of Kenitra (North-East of Morocco) are rejected without preliminary processing by six emissaries into the Sebou river, the Atlantic Ocean and the Fouarate lake. The present study is based on a qualitative and quantitative analysis of the wastewater parasites load of the "Ville Haute" urban district of Maamora (Kenitra, Morocco). Untreated wastewater samples taken at the exit of the urban emissary are pretreated and analysed by the modified Bailenger method at the parasitological and hydrobiological laboratory of the Sciences Faculty of Kenitra (Ibn Tofail University). For diagnostic confirmation purposes, other complementary analysis were made at the parasitological laboratory of the National Institute of Hygiene (Rabat) The results obtained pointed to the existence of the helminths parasites eggs of Ascaris spp., Toxocara spp., Trichuris spp., Hymenolepis spp., Taenia spp and Fasciola hepatica species with respective concentrations of 3 eggs/L, 17 eggs/L, 7 eggs/L, 2 eggs/L, 1 eggs/L and 1 egg/L. The mean concentration is about 31 eggs/L of untreated wastewater. Furthermore, on the samples examined, the percentages of positives tests is 86% for nematodes, 10% for cestodes, and 4% for trematodes. At the end of this preliminary study we insist on the very high level of parasitic helminths transported by untreated wastewater and we recommend that those wastewater be processed before there are recycled in the Sebou river.
