Évaluation de la diversité et de la charge parasitaire des lacs de la ville de Yamoussoukro en Côte d’Ivoire

Abstract

Objectives: Water, source of life is essential for all living beings. After its use, the water is loaded in various elements modifying its physical, chemical and biological characteristics. One of the most serious environmental problems is the problem of sanitation. Indeed, human activity leads to the production of wastewater discharged daily into the wild. Methodology and results: Twenty-eight waste water samples were collected from eight Yamoussoukro lakes from sterile containers. The method of Bailenger was used for the detection of parasites. The specific recognition and enumeration of the parasites was done using an optical microscope Prevalences observed were compared between lakes and by parasite species. A total of 13 species of parasites: Ankylostoma sp., Strongyloïd sp., Ascaris sp., Nematodirus sp., Trichuris sp., Toxocara sp., Capillaria sp., Ascaridia galli, Enterobius vermicularis,Taenia sp., Hymenolepis diminuta., Entamoeba coli., Entamoeba histolytica et les larves de Strongles were detected in the waters of Yamoussoukro lakes. Helminth eggs are almost present in all investigated lakes with variable parasite loads. Three species gave very high parasite loads: The species Ankylostoma sp was found in all lakes. Strongyloids and Ascaris sp had prevalence rates of 100 % and 87.5 %, respectively. At the level of the parasite load of the lakes, Lake N ° 5 was the most parasitized with a prevalence of 100 % on all the parasites, then the lakes N ° 1, 6 and 8 (69,2 %) then the Lakes G0, 9 and 10 (53.8 %). Conclusion and application of results: Parasitological analysis show that Yamoussoukro lakes are contaminated by parasites of medical importance. The infestation of these waters with pathogens prohibits their use in agriculture, which is not commonly observed in the field.

Parasitological Quality Evaluation of Pipe Waters in Abidjan, the Capital City of Cote D’ivoire

“…At the sampling sites, those of the AM (Macory-Koumassi), MG (Yopougon) and ZB (Macory-Koumassi) with a respective prevalence of 1.86%, 3.72% and 4.46% are relatively the According to Raweh et al [22] and EL Guamri et al [31], the concentration of parasites in wastewater is sensitive to the demographic structure of those connected to the liquid sanitation network. Indeed, the municipalities of Yopougon and Abobo-Adjamé are the largest municipalities of Abidjan, with the highest population density of 1,071,543 and 1,403,636 [20].…”

“…It is bordered to the south by the "Ebrié" lagoon, which covers approximately 16% of its area and the Atlantic Ocean. Since 1978, it has included ten communes (Abobo, Adjamé, Attécoubé, Cocody, Koumassi, Marcory, Plateau, Port-Bouët, Treichville, Yopougon) [19], and its population was estimated to be 4.4 million inhabitants in 2014 [20].…”

Monitoring the Influence of Anthropogenic Pollution on the Quality of Irrigation Water for Market Gardening in Yamoussoukro, Côte d’Ivoire

“…Indeed, the timing of watering, the quality and direct contact of the water with the edible part of the plant are all risk factors (WHO, 2012). For example, vegetables produced around the Yamoussoukro lakes may pose food threats because they are eaten raw and generally without good decontamination practices (Sylla et al, 2019).…”

“…Monitoring the Influence of Anthropogenic Pollution on the Quality of Irrigation Water for Market Gardening in Yamoussoukro, .... In addition, coliform counts are an indicator of the presence of pathogenic bacteria (W HO, 2012;Sylla et al, 2019). Thus, the objectives of this study were to monitor the dynamics of bacterial pollution in the lakes of Yamoussoukro and its impact on the contamination of market garden crops watered by the lake waters.…”
