新疆普氏野马消化道线虫的调查

Research of Gastrointestinal Nematodes in Sinkiang Equus przewalskii

摘要: 为了解新疆普氏野马消化道寄生虫病的流行情况，对该马场92匹马进行了抽样调查，采用饱和盐水漂浮法和麦克马斯特氏虫卵计数法对粪便样品中的虫卵进行鉴定和定量检查。实验结果表明：线虫最高感染率为69%，优势虫种为毛细线虫、马副蛔虫、马圆线虫和三齿细颈线虫，感染强度均为100个/g粪~500个/g粪。通过本次调查，对普氏野马消化道寄生虫种类有了进一步的了解，为今后马匹针对性驱虫奠定了基础，对普氏野马健康繁殖和发展具有实际意义。

Abstract: In order to learn about the prevalence of gastrointestinal parasitosis of Sinkiang Equus przewalskii, 92 horses were sampled. Saturated saline floatation method and McMaster’s egg count method were employed to authenticate and quantitatively check the eggs in the stool samples. According to the experimental results, the highest infection rate of nematodes was 69% and the predominant eggs were capillary nematode, parascaris equorum, strongylus equinus and three teeth nematode, whose infection intensity were all 100 to 500 eggs per gram of feces. This research facilitates people to learn more about the species of gastrointestinal parasite in Sinkiang Equus przewalskii, lays the foundation of targeted parasite expelling in horses and thus is of practical significance for reproductive health and development of Equus przewalskii.
