| Abstract: | Helminth parasites were collected from 13 grysbok, Raphicerus melanotis, 12 common duikers, Sylvicapra grimmia, 24 Angora goats and 24 Boer goats killed on a farm in Valley Bushveld in the eastern Cape Province. Nematodes belonging to 9 species and a further 2 genera and cestodes belonging to 1 species and a further genus were recovered from the grysbok. Of these, worms of the genus Skrjabinema, Trichostrongylus rugatus, Trichostrongylus pietersei and Nematodirus spathiger were the most prevalent and the most numerous. An amended list of the helminths of grysbok is included. Seven nematodes, identified to species and 1 identified to genus were recovered from the common duikers. N. spathiger and Setaria scalprum were the most prevalent, while N. spathiger and Trichostrongylus axei were the most abundant. The Angora goats were infested with at least 10 nematode species and 2 cestodes and the Boer goats with at least 14 nematode species. With the exception of Trichostrongylus pietersei, the Boer goats harboured more nematodes of each species than did the Angora goats. Nematodirus spp. and worms of the genus Skrjabinema were most numerous in Angora goats, and Nematodirus spp. and Teladorsagia circumcincta in the Boer goats. No clear pattern of seasonal abundance was evident for any of the helmith species in the various hosts. |
