Abstract

The parasitological examination of Ava stream in Abakpa Nike, Enugu state, Nigeria, was investigated to identify the species and load of parasites in the stream. Five different sites were sampled; these sites were chosen based on the different anthropogenic activities going on around these sites. One litre sample each was collected from these sites and were preserved by the addition of 10% formaldehyde (2 ml/L), and were transported to the laboratory. The samples were examined using the flotation technique. The species of parasites identified include Schistosoma haematobium, Ascaris lumbricoides, Hymenolepsis nana, Enterobius vermicularis, Trichuris trichuria, Diphybotrium latum, and Taenia species. Samples of Ogburugbu, recorded the highest egg count/L, as well as the highest percentage occurrence, and were followed closely by Ugwuagor, while Agbalike site recorded the least occurrence. This research has helped to identify the possible health risk of consuming raw vegetables and fruits irrigated with wastewater and organic manure sources and the unhygienic activities of the people.
