Identification of potentially zoonotic parasites in captive orangutans and semi‐captive mandrills: Phylogeny and morphological comparison

Cysts and trophozoites of vestibuliferid ciliates and larvae of Strongyloides were found in fecal samples from captive orangutans Pongo pygmaeus and P. abelii from Czech and Slovak zoological gardens. As comparative material, ciliates from semi‐captive mandrills Mandrillus sphinx from Gabon were inc...

Description
Summary:	Cysts and trophozoites of vestibuliferid ciliates and larvae of Strongyloides were found in fecal samples from captive orangutans Pongo pygmaeus and P. abelii from Czech and Slovak zoological gardens. As comparative material, ciliates from semi‐captive mandrills Mandrillus sphinx from Gabon were included in the study. Phylogenetic analysis of the detected vestibuliferid ciliates using ITS1‐5.8s‐rRNA‐ITS2 and partial 18S ribosomal deoxyribonucleic acid (rDNA) revealed that the ciliates from orangutans are conspecific with Balantioides coli lineage A, while the ciliates from mandrills clustered with Buxtonella‐like ciliates from other primates. Morphological examination of the cysts and trophozoites using light microscopy did not reveal differences robust enough to identify the genera of the ciliates. Phylogenetic analysis of detected L1 larvae of Strongyloides using partial cox1 revealed Strongyloides stercoralis clustering within the cox1 lineage A infecting dogs, humans, and other primates. The sequences of 18S rDNA support these results. As both B. coli and S. stercoralis are zoonotic parasites and the conditions in captive and semi‐captive settings may facilitate transmission to humans, prophylactic measures should reflect the findings. Potentially zoonotic parasites Strongyloides stercoralis and Balantioides coli were found in fecal samples from captive orangutans (Pongo pygmaeus and P. abelii) in Czech and Slovak zoological gardens. Probably nonzoonotic ciliates Buxtonella‐like were detected in semi‐captive mandrills in Gabon. Research Highlights Detection of potentially zoonotic Balantioides coli in captive orangutans and probably nonzoonotic Buxtonella‐like in semi‐captive mandrills Assessment of genetic diversity of zoonotic Strongyloides stercoralis in captive orangutans
