Prevalence and Parasite Composition of Gastrointestinal Parasites in the Endangered Tibetan Antelope (Pantholops Hodgsonii) from the Calving Ground of Hoh Xil Nature World Heritage Site, Qinghai, China

A comprehensive survey of gastrointestinal parasites in the endangered Tibetan antelope (Pantholops hodgsonii) on its calving grounds at Qinghai Hoh Xil revealed widespread and diverse parasite infections. The study found that 93% of fecal samples tested positive for nematodes, 36% for cestodes, and an astonishing 99% for coccidian oocysts, with an average of 3.4 parasite species per individual. Coinfections involving five parasite genera were detected in 19% of samples, highlighting the complex parasitic burden faced by this vulnerable species. The high prevalence of Trichostrongylus, Marshallagia, and Eimeria infections suggests these parasites pose significant long-term risks, particularly as climate change increases warmth and moisture in the region. Researchers analyzed 238 fecal samples collected in July 2018 using flotation techniques to identify eggs, oocysts, and nematode larvae, providing critical baseline data for monitoring future health trends.
