Abstract: Objective To provide basic data for understanding and preventing the spread of zoonotic parasitic diseases caused by Marmota baibacina across the border between China and Mongolia. Methods In 2019, M. baibacina was captured by patrol and trapping in the border area of China-Mongolia Hongshanzui port, and investigated the distribution and epidemiological characteristics of intestinal parasites in M. baibacina. The species of the parasites was identified after hematoxylin staining, dehydration, xylene clearing, and paraffin embedding. Results Two species of parasites, Paranoplocephala ryjikovi and Baylisascaris laevis, were found in the intestine of 50 M. baibacina, with an overall infection rate of 84.00%. A total of 321 parasites were obtained, with infection intensities of 2-80. Excretion of tapeworm segments from the marmots was observed, and eggs were detected in feces. The infection was prevalent across the whole border area of Hongshanzui. Conclusion It is the first time to find P. ryjikovi and B. laevis in the intestine of M. baibacina in the border area of China-Mongolia Hongshanzui port, which provides a basis for preventing the international spread of zoonotic parasitic diseases across the China-Mongolia border area and promoting the healthy development of animal husbandry.

摘要: 目的 为了解和防控灰旱獭导致的人兽共患寄生虫病在中国-蒙古国边境(中蒙边境)两国间的传播提供基础资料。方法 2019年在中蒙红山嘴口岸边境线区用巡查、布套等方法采集灰旱獭,研究其消化道寄生虫的分布、流行特点。取虫体用苏木素染色、脱水、二甲苯透明固定石蜡包埋进行种类鉴定。结果 在50只灰旱獭肠道中发现立式副裸头绦虫、光滑贝蛔虫2种虫体,总感染率为84.00%,检出虫体321条,感染强度为2~80,并观察到灰旱獭排出绦虫节片及粪便中检出虫卵的现象,其感染范围分布于中蒙红山嘴整个边境区。结论 首次在中蒙红山嘴边境区灰旱獭肠道发现立式副裸头绦虫和光滑贝蛔虫2种寄生虫病原体,为防控人兽共患寄生虫病在中蒙边境区国际间的扩散传播及畜牧业健康发展提供了依据。
