At first , study on antigenic variation in trypanosoma evansi from a clonal stock in rabbit was carried out 首先进行的是伊氏锥虫一个单克隆株在5只兔体内连续抗原变异的研究。

He proed to be infected by trypanosoma eansi , a trypanosome which is usually a parasite of arious animals , particularly cattle 他被证实感染了伊氏锥虫，这种锥虫是一种在各种动物，特别是牛中常见的寄生虫。

In order to find out regularity of antigenic vareation , a cloned population of trypanosoma evansi stock yntatl was infected sequentially to 5 new zealand rabbits during 150 days . competing the ablity of anti - trypanosoma evansi between 3 different antibody bank derived from rabbits , setting up by different means 随后根据所获得的抗原变异体( vatvariableantigentype ) ，建立抗伊氏锥虫兔血清抗体库?原混血清库、虫体血清库、 vsg ( variablesurfaceglycoprotein )血清库，并对抗体库的抗虫效果进行检测。
