Coprologic evidence of gastrointestinal helminths of forest baboons, Papio anubis, in Kibale National Park, Uganda

Abstract

The gastrointestinal parasites of baboons have been well characterized from savannah and desert habitats, but little is known about their gastrointestinal parasites in forest habitats. From May to June 2004, we collected 41 fecal samples from free-ranging olive baboons (Papio anubis) within the forested Kibale National Park, Uganda. Samples were examined to determine the prevalence of gastrointestinal helminths in this forest dwelling population of olive baboons. The prevalence of nematodes identified from fecal flotation was Oesophagostomum sp. (85%), Trichostrongy1us sp. (22%), Trichuris sp. (46%), Strongyloides sp. (44%), Ternidens sp. (5%), Abbreviata sp. (2%), and Molineus sp. (2%). Flotation techniques also recovered unidentified eggs, probably of hookworm origin (22%). No parasite eggs were recovered by sedimentation of eight samples. Coproculture techniques usin 13 of the 41 samples recovered larvae from Oesophagostomum sp., Strongyloides sp., an Trichostrongylus sp. The high prevalence of nematodes recovered in this study seems to support previous theories of high nematode infections in forested habitats. © Wildlife Disease Association 2008.
