Abstract

Our objective was to provide baseline information on the gastrointestinal parasites of the female Tibetan antelope (Pantholops hodgsonii) on its calving ground at the Zhuonai Lake region, in the Hoh Xil Nature World Heritage site, Qinghai, China. On 3 July 2018, 238 freshly deposited fecal samples were collected from the calving grounds and analyzed by flotation technique to recover eggs, oocysts, and nematode larvae. All fecal samples demonstrated the presence of gastrointestinal parasites: 93% (221/238) had nematodes, 36% (86/238) had cestodes, and 99% (235/238) had coccidian oocysts. For each Tibetan antelope, mean (SD) parasite species richness was 3.4 (1.3). Coinfections with five parasite genera were found in 19% (45/238) of fecal samples. These results showed that prevalence of Trichostrongylus, Marshallagia, and Eimeria infections in these Tibetan antelopes were sufficiently high to suggest long-term monitoring be implemented because the climate there is becoming warmer and moisture is increasing, both presumably due to the influence of global warming which, in turn, may be contributing to increased infection risks with these parasites.
