Studies on the parasites of zebras. 1. Nematodes of the Burchell's zebra in the Kruger National Park

Abstract

Nineteen species of gastro-intestinal nematodes were recovered from 10 Burchell's zebra. These include: Cyathostomum alveatum, C. montgomeryi and C. tetracanthum; Cylicocyclus auriculatus, C. gyalocephaloides, C. insigne and C. triramosus; Cylicodontophorus schürmanni and Cylicodontophorus n. sp., Cylicostephanus bidentatus, C. calicatus and C. minutus; Poteriostomum ratzii, Craterostomum acuticaudatum, Triodontophorusminor, Habronema majus, H. muscae, H. zebrae, and Draschia megastoma, as well as Cylindropharynx spp. The highest burdens encountered were those of Cylicocyclus triramosus (159 491), Cylindropharynx (19 875), Cylicocyclus auriculatus (15 792), Cylicostephanus calicatus (16 658) and Cyathostomum tetracanthum (13 723). The nematodes consistently present in all zebras were: Cylicostephanus calicatus, Cylindropharynx spp. and Draschia megastoma.
