摘　　要：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 paper reports the results of investigations and comparative analysis of characteris- tics of Echinococcus granulosus infection in cattle and sheep in different parts of Xinjiang dur- ing the period 1990-1992.The standardized morbidity rate for cattle hydatidosis was 74.53% in Altay,63.68% in Ili and 46.23% in Hotan,respectively,significantly higher in Altay and Ili than in Hotan.The infection rates of liver and lung were basically similar.The intensity of infection expressed as hydatid cyst index(the mean cyst burdens per animal af- fected)was higher in Ili(10.56)than in Hotan(7.05)and Altay(7.11).The ratio of brood cysts in cattle affected by hydatid disease was significantly higher in Ili than in Hotan and Al- tay,being 26.47%,6.18% and 7.94%.The ratio of cattle with calcified foci was 21.2% for Hotan,12.54% for Ahay and 10.76% for Ili,the tendency of calcification for cattle in Hotan being significantly higher than that in the latter two areas. The morbidity rate for sheep hydatidosis was 43.75% in Altay and 44.88% in Qira.The infection rate of liver was higher than that of lung,and the infection ratio of liver to lung was 1:0.55 for Altay and 1:0.72 for Qira,somewhat more lung infections being in Qira than in Altay.The intensity of infection expressed as hydatid cyst index was higher in Qira (8.74)than in Altay(4.99).The percentage of diseased sheep with brood cysts was signifi- cantly higher in Altay(80.80%)than in Qira(40.84%).The ratio of calcified foci in dis- eased sheep between the two areas varied considerably,being higher in Qira(16.97%)than in Altay(10.34%).The authors attribute the significant difference in cattle and sheep E. granulosus infection between different parts of Xinjiang to the biological characteristics of different strains.
