Infective situation of Echinococcus in dogs in Gannan Tibetan Autonomous Prefecture

目的掌握甘南藏族自治州终末宿主犬细粒棘球绦虫和多房棘球绦虫感染状况,为该地区包虫病的传播动力学研究及开展大规模包虫病防治做好前期工作。方法选择碌曲县和玛曲县当地家犬、牧羊犬,采用15%槟榔碱溶液(21mg/kg体重)导泻后检查成虫,随机捕杀当地无主野犬,解剖十二指肠检查成虫。结果终末宿主犬细粒棘球绦虫感染率为22.97%(17/74),多房棘球绦虫感染率5.41%(4/74),合计感染率为28.38%,感染犬的感染度为43.29条/只。未发现两种绦虫混合感染。结论甘南藏族自治州犬细粒棘球绦虫感染率较高,并有多房棘球绦虫感染。

Objective To grasp the infective situation of Echinococcus in dogs in Gannan Tibetan Autonomous Prefecture, Gansu Province. Methods Local domestic dogs or shepherd dogs in Luqu and Maqu County were chosen and treated with 15% arecoline solution （21 mg/kg body weight） for catharsis, and the adults were checked. The wild dogs were randomly killed to check adults. Results The investigative results showed that the infective rate of Echinococcus granulosus （Eg） was 22.97% （17/74） and Echinococcus multilocularis（Em） was 5.41%（4/74） in dogs, but no mixed infections were found. The total infective rate was 28.38% and the infective degree of infective dogs was 43.29. Conclusion The results show that the distribution of Eg is widespread but Em is a small quantity of prevalence in dogs in Gannan Tibetan Autonomous Prefecture.
