目的了解不同生产方式条件下新疆家犬细粒棘球绦虫感染情况,为今后包虫病防治工作提供科学依据。方法采取分层抽样的方法,在全疆94个县(市)以行政村为单位按牧区、半农半牧区、农区和城镇进行分层,每个县调查16个村,被抽中的调查村中每村抽取20个养犬户(养犬户数不足时从邻近村补足),每户仅采集1条犬的粪样,每个调查县(市)采集犬粪样320份;对采集的犬粪采用粪抗原-ELISA方法检测,采用Spss 17.0统计软件对不同生产方式条件下犬粪抗原阳性率进行卡方检验。结果全疆94个县(市)共采集犬粪样29 874份,粪抗原阳性719份,阳性率为2.41%;其中牧区犬粪抗原阳性率3.75%、半农半牧区2.24%、农区1.98%、城镇2.46%,不同生产方式条件下犬粪抗原阳性率差异有统计学意义(χ2=45.073,P<0.001),其中牧区犬粪抗原阳性率显著高于其他生产方式条件下粪抗原阳性率,差异有统计学意义(χ2=43.102,P<0.001)。结论目前新疆牧区犬细粒棘球绦虫感染率最高,其次为城镇,在今后的包虫病防治工作中应重点加强牧区犬的管理和驱虫,同时做好城镇地区流浪犬的管理和控制,切断传染源,做好包虫病的防治工作。
Objective To understand the infection status of Echinococcus granulosus in domestic dogs in different production modes in order to provide a scientific basis for future prevention and control of echinococcosis. Methods Stratified sampling method was used to stratify the pastoral areas, semi-agricultural semi-pastoral areas, agricultural areas and towns in 94 counties (cities) in Xinjiang based on the administrative villages. 16 villages were investigated in each county, In the investigation, 20 dog-raising households were collected from each village in the village (from nearby villages when the number of dog raising was insufficient), only 1 dog’s fecal sample was collected per household, and 320 dog-feces samples were collected for each surveyed county (city) The collected dog feces were detected by fecal antigen-ELISA. Spss 17.0 statistical software was used to test the positive rate of canine antigen in different production methods. Results A total of 29,874 canine samples were collected from 94 counties in Xinjiang. The positive rate of stool antigen was 2.41%. The positive rate of canine antigen was 3.75% in pasture, 2.24% in semi-agricultural and semi-pastoral area, 1.98 %, And 2.46% in urban areas. The positive rates of canine antigen in different production methods were significantly different (χ2 = 45.073, P <0.001). The positive rate of canine antigen in pasture was significantly higher than that in other production methods , The difference was statistically significant (χ2 = 43.102, P <0.001). Conclusions At present, the infection rate of Echinococcus granulosus is the highest in Xinjiang pastoral area, followed by that in urban areas. In the future prevention and control of echinococcosis, the management and deworming of dogs in pastoral areas should be emphasized. At the same time, management and control of stray dogs in urban areas should be well done. Cut off the source of infection, good prevention and treatment of hydatid disease.
