A total of 25 grey rhebuck, Pelea capreolus, and 16 bontebok, Damaliscus dorcas dorcas, were shot for parasite recovery at bi-monthly intervals in the Bontebok National Park, south-western Cape
Province, from February 1983 to December 1983 and February 1983 to February 1984, respectively.
The grey rhebuck and the bontebok each harboured 9 nematode species and the latter animals 1 cestode species. Ostertagia hamata was most abundant and most prevalent in the grey rhebuck and Longistrongylus curvispiculum and Nematodirus spathiger in the bontebok. Longistrongylus schrenki is
recorded for the first time in grey rhebuck, and Trichostrongylus falculatus and Moniezia expansa in bontebok. The total nematode burdens of the bontebok were considerably larger than those of the grey rhebuck.
No clear pattern of seasonal abundance for the helminths of either host species was evident.
