【摘要】：采集川西北阿坝州红原县和甘孜州理塘县总计402份牦牛粪便样本,采用廖氏计数法(改良)对4类常见体内寄生虫虫卵进行形态学观察并计数,以了解该地区牦牛体内寄生虫感染情况。结果表明,红原县牦牛体内线虫、绦虫、吸虫、球虫虫卵或卵囊(EPG或OPG)的平均感染量分别为11.59、23.77、42.45和14.72,总感染量为92.53(48.91~154.90);平均感染率分别为18.01%、36.62%、44.68%、17.37%,总感染率为76.39%,表明吸虫是红原的优势寄生虫虫种,绦虫也是重要虫种。理塘县牦牛线虫、绦虫、吸虫、球虫的虫卵或卵囊(EPG或OPG)的感染量分别为52.38、13.10、20.24和1.19,总感染量为86.90;感染率分别为52.38%、19.05%、23.81%和2.38%,总感染率为78.57%,表明线虫为该地区的优势虫种。红原县和理塘县两地牦牛体内寄生虫虫卵感染主要以单一感染和二重感染为主,二者的总和分别为69.31%和78.57%,分别占总感染率的90.73%和100%。本研究结果证实牦牛寄生虫病目前仍是危害牦牛生产和当地牧民健康的一类重要疫病。该研究丰富了川西北高原地区牦牛体内寄生虫病的流行病学资料,为该地区牦牛寄生虫病的防控提供了理论依据。
[Abstract]:A total of 402 yak feces samples were collected from Hongyuan County, Aba Prefecture, Northwest Sichuan and Litang County, Ganzi Prefecture. The eggs of four common parasites were observed and counted by Liao's counting method (improved). The results showed that the nematode, tapeworm and trematode in Hongyuan county yak, The average infection rates of egg or egg cyst EPG or OPG were 11.59, 23.77 and 14.72, respectively, the total infection rate was 92.53, 48.91 and 154.90, the average infection rate was 18.01C 36.62 and 44.68, and the total infection rate was 76.393.The results showed that trematode was the dominant parasitic species of erythrogen, tapeworm was also an important species, and Yak nematode was also important in Litang County. Tapeworm, trematode, The infection rates of egg or egg cyst EPG or OPG of coccidiosis were 52.380.13.101020.24 and 1.19, respectively, and the total infection rate was 86.90, and the infection rate was 52.380.19.05% and 2.38%, respectively. The total infection rate was 78.577.The results showed that nematode was the dominant species in this area. The yaks of Hongyuan and Litang counties were mailed in the yaks of Hongyuan County and Litang County, respectively, and the infection rates were 52.38% and 2.38% respectively, which indicated that the nematode was the dominant species in this area. Single infection and double infection were the main infection in eggs. The sum of them were 69.31% and 78.57, accounting for 90.73% and 100th of the total infection rate, respectively. The results of this study confirm that yak parasitosis is still an important epidemic disease that endangers the production of yaks and the health of local herdsmen. This study enriches the high level of northwest Sichuan. Epidemiological data of parasitic diseases in yaks in the original area, It provides a theoretical basis for the prevention and control of yak parasitic disease in this area.
