Abstract:

Burchell's Zebra ( Equus Burchelli Antiquorum) were sampled for gastrointestinal parasites at the Lewa Downs Game Ranch in Isiolo District between 4/7/95 and 11/7/95. The stomach, small intestines and abdominal cavity were searched for parasites. The parasites were identified to genus level but in some cases to species level. Feacal egg counts, hematology and serum biochemistry screening were also performed. All animals were infested with at least three genera of gastrointestinal parasites including at least one nematode genus. A total of nine genera were recovered representing eight families. These included six nematode families, Strongylidae, Strongylinae, Atractidae, Oxyuridae, Spiruridae, and Setaridae one cestode family, Anoplocephalidae and one family of the larvae of Gasterophilus bot flies, Gastrophilidae. The most prevalent families were Atracidae (100%) and Strongylinae (80%). The mean total worm burden was 78,764. The average of individual genera varied from 0-77,890worms. The average worm burdens were higher in females than in males. In comparing the mean total egg counts, there were generally higher egg counts in animals with higher worm burdens. Hematology results were within baseline values for Burchell's zebra. Blood biochemistry showed high levels of Alkaline Phosphatase, Creatine Kinase, Lactase dehydrogenase and Aspartate transaminase was partly attributed to exertion before death
