Typically, H. contortus has spicules 0,466 ± 0,085 mm long, but those recovered from vaal ribbok had spicules 0,581 ± 0,02 mm long and were recovered in large numbers from this antelope only. This indicates that the nematode is probably a definitive parasite of vaal ribbok, and its occurrence in bontebok must be regarded as accidental.en©ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). ©University of Pretoria.
