Background: Primates can harbour parasites that could be pathogenic or not for humans and primates themselves. It is necessary to know the parasitological situation of the primates that are under surveillance in the park.

Aim: The purpose of this study was to estimate the prevalence and diversity of gastrointestinal parasites, including zoonotic potential parasites, in baboons in the Niokolo-Koba National Park located in Senegal.

Method: Faecal samples (n=50) from two groups of Baboons (A and B) were collected in October 2019. Faecal samples were processed using the flotation technique and the modified Ritchie method. Slides were examined microscopically, and the parasite identification was based on morphology, colour, and parasite content.

Results: A total of seven nematodes (Strongyloides sp., Trichirus sp., Ancylostoma sp., Mammo monogamus, Enterobius sp., Strongyloides stercoralis, Strongle digestif), one cestode (Bertiella sp.) and one trematode (Fasciolopsis sp.) were identified. The overall prevalence was 78% while prevalence of poly-infected samples was 49%. The parasite with zoonotic potential, Strongyloides stercoralis, was identified in group B samples. Trichuris sp. which is common and pathogenic to humans and primates was present with a prevalence of 52% and of 32% in groups A and B, respectively.

Conclusion: These results suggest that baboons are infested with zoonotic parasites and this situation could expose people working in this park to infection. Contact between humans and these baboons or their faeces could expose to infection with zoonotic parasites.
