HELMINTH DYNAMICS IN URBAN WASTEWATER FROM THE BORIBANA COLLECTOR (ATTECOUBE, ABIDJAN)

A parasitological study was conducted on wastewater passing through the Boribana collector, located in the commune of Attecoube (District of Abidjan, CotedIvoire), to assess its helminth egg load. Samples were collected from November 2015 to May 2016 at four sites distributed along the collector. The analysis identified fourteen (14) helminth taxa belonging to three classes: Nematodes (7 taxa), Trematodes (4 taxa) and Cestodes (3 taxa). Nematodes were found to be the most diverse. The most frequently detected species were Ascaris lumbricoides, Trichuris trichiura and Taenia sp., with Ascaris lumbricoides also being the most abundant species. The average helminth egg concentration ranged from 9.53 eggs/L (station D) to 146.15 eggs/L (site A). A peak in parasite load was observed during the local rainy season, suggesting a significant seasonal influence on parasitic contamination of wastewater.
