本文报告1990~1992年在新疆不同地区对牛和绵羊细粒棘球蚴感染特征进行调查和比较分析的结果。牛包虫病标化患病率在阿勒泰、伊犁、和田三地分别为74.53%、63.68%和46.23%,前两地明显高于和田。肝和肺的感染率基本相等。感染强度以包囊指数(平均每只患病动物的荷囊数)表示,以伊犁较高为10.56.和田与阿勒泰相等分别为7.05和7.11。包虫病牛中带有育囊的比例伊犁明显高于和田与阿勒泰,分别为26.47%、6.185和7.94%。三地带有钙化灶的病牛所占比率各为和田21.2%,阿勒泰12.54%,伊犁10.76%。和田牛的钙化趋势显然高于后两地。绵羊细粒棘球蚴患病率在阿勒泰和策勒各为43.75%和44.88%。肝脏感染高于肺脏.两地肝、肺感染比值各为1:0.55和1:0.72。策勒肺的感染略高于阿勒泰。感染强度(包囊指数)策勒(8.74)高于阿勒泰(4.99)。带有育囊的绵羊数阿勒泰显然高于策勒,各为80.80%和40.84%。两地绵羊病灶钙化比例有明显区别,策勒高于阿勒泰(16.97%和10.34%)。结果表明新疆不同地区之间牛和绵羊细粒棘球蚴感染有明显不同,作者认为这是不同虫株生物学特征的反映.
This article reports from 1990 to 1992 in different regions of Xinjiang cattle and sheep Echinococcus granulosus infection characteristics of the survey and comparative analysis of the results. The prevalence of bovine tuberculosis was 74.53%, 63.68% and 46.23% respectively in Altay, Ili and Wada, the former two were significantly higher than that of Hetian. The prevalence of liver and lung infection is basically the same. The intensity of infection was expressed in terms of the cyst index (average number of pockets per diseased animal), with Ili being 10.56 higher and Wada equal Aletai respectively 7.05 and 7.11. The ratio of Ili with cysts in hydatid disease was significantly higher than that of Hotan and Aletai, which were 26.47%, 6.185 and 7.94% respectively. The proportions of sick cattle with calcification in the three places were 21.2% in Wada, 12.54% in Aletai and 10.76% in Ili. Wada beef calcification trend is clearly higher than the latter two places. The prevalence of Echinococcus granulosus in sheep was 43.75% and 44.88% in Aletai and Cele. The liver infection was higher than that of the lungs, and the ratios of liver and lung infection were 1: 0.55 and 1: 0.72 respectively. Celer lung infection slightly higher than Altay. Infection intensity (cyst index) Celer (8.74) was higher than Aletai (4.99). The number of sheep with cysts was significantly higher than Cele, 80.80% and 40.84% respectively. There was a significant difference in the proportion of calcification in sheep lesions between the two regions, Cele was higher than Altay (16.97% and 10.34%). The results showed that there were significant differences in the infection of Echinococcus granulosus between cattle and sheep in different regions of Xinjiang. The author believes this is a reflection of the biological characteristics of different strains.
