Clinical case report of oesophagostomiasis in captive Hamadryas Baboon (Papio Hamadryas) in Ethiopia

Abstract

Oesophagostomum spp is a nodule causing nematode found in livestock and primate species in Sub-Saharan Africa. The L3 infectious larvae invade the colonic wall, forming nodules in which the larvae continue their development. It can be a serious zoonotic risk in some areas in Africa. Primates are natural hosts for the parasite and do in general not show any symptoms. We present here a clinical case of Oesophagostomiasis in a captive hamadryas baboon (Papiohamadryas) in Ethiopia who died of acute peritonitis as a result of the infection with the parasite. Post-mortem was performed and colon tissue analyzed by cytology. This case highlights the importance of Oesophagostomiasis in captive baboons that undergo stress full events and the need for adequate management.
