The developing immunity of sheep to Trichostrongylus colubriformis infections was described by a mathematical function. The rate of adult establishment was assumed to be a measure of the host's acquired immunity to this parasite. Prediction of establishment from infection rate and host age was used to estimate worm burden, worm rejection and arrested development.
用一个数学函数描述了绵羊对蛇形毛圆线虫感染的免疫发展情况。成虫定居率被假定为宿主对该寄生虫获得性免疫的一种度量。根据感染率和宿主年龄对定居情况进行预测,以估计虫负荷、驱虫和发育停滞情况。
