Thompson’s gazelles are an important part of wildlife in Kenya and their meat is utilised for human consumption. Gastrointestinal (GIT) parasites however, may be a limiting factor to their management and utilisation. A survey of the prevalence and intensity of gastrointestinal parasites in Thompson’s gazelles was conducted on a game ranch in October 2003. 31 male and female gazelles were captured using net screens. Fecal samples were collected directly from their rectum. Nematode EPG, presence of fluke eggs, cestode eggs and coccidial oocyts were determined on each sample using a modified McMaster technique. All the 31 captured gazelles were shedding strongyle-type nematode eggs and coccidial oocyts. Trichuris eggs were found in only 1 out of 3 fecal samples from the young males and in none of the samples from 6 young females and 22 adult gazelles. Fluke and cestode eggs were not found in any of the samples. Fecal cultures revealed predominance of Haemonchus, Gazellostrongylus and Trichostronglus in fecal samples from the captured gazelles.
