Gastro-intestinal parasites of sympatric red panda and livestock in protected areas of Nepal

Abstract

Background: Disease transmission among humans, domestic animals and wildlife can have profound consequences in human health, wildlife conservation and maintenance of biodiversity. The issue of disease transmission can be particularly important for threatened wildlife species, yet such information remains scarce due to logistic constraints and government regulation on animal handlings. The red panda (Ailurus fulgens) is one of the globally threatened species challenged with habitat fragmentation and human disturbance. In Nepal, livestock grazing is recognised as one of the major threats to the red panda. Aim: We aimed to provide the first empirical data on gastro-intestinal parasites for sympatric livestock and red panda from two geographically isolated regions in Nepal. Methods: In this study, we systematically sampled, and examined the faecal of livestock and red panda in two separate protected areas to provide the first empirical data on their gastro-intestinal parasite, including the prevalence, parasite richness and load. Results: We documented 11 parasite taxa (7 nematodes, 2 cestodes, 1 trematode and 1 coccidian), of which 8 are shared by both livestock and red panda. Furthermore, parasite prevalence, parasite load and parasite richness were generally higher in the livestock than the red panda. Conclusion: The data provided from this systematic survey on parasites of sympatric livestock and red panda in wild raises the concern about the potential role of livestock mediating disease dynamics in the red panda. Our study suggests that cross-transmission of parasites between livestock and red panda are likely, and the livestock may be a competent agent bringing disease to both red panda and human. Therefore, managing human-livestock-wildlife contact to reduce disease risk to all groups should be a key component in conservation planning of protected areas.
