旋毛虫各隔离种对小鼠的感染性研究

摘要

Infectivity of Trichinella from swine and dog,and the international standard Trichinella isolates:T.spiralis and T.nativa in mice was compared in Heilongjiang province, China.It was found that infectivity of 4 Trichinella isolates in mice was significantly different.Swine isolate and T.spiralis were highly infective to mice with Reproductive Capacity Indexes(RCI)of 121.01 and 149.86 respectively,however,mice were relatively refractory to dog isolate and T.nativa with RCIs of 60.89 and 55.15 respectively.On the basis of the results,it is concluded that Trichinella from swine and dog in Heilongjiang province, China belong to Trichinella spiralis and Trichinella nativa respectively.%比较研究了黑龙江省猪、犬旋毛虫及国际标准虫种：旋毛形线虫(Trichinella spiralis)和本地毛形线虫(Trichinella nativa)对小鼠的感染性异同。结果表明，四者对小鼠的感染力存在着显著差异，猪旋毛虫和旋毛形线虫在小鼠体内的繁殖力指数(RCI)分别为121.01±7.80和149.86±7.47；而犬旋毛虫和本地毛形线虫的RCI分别为60.98±5.05和55.15±4.69。由实验结果可认为黑龙江省的猪旋毛虫相当于旋毛形线虫，而犬旋毛虫相当于本地毛形线虫。
