鱼类三代虫的寄主特异性分析

分析了迄今为止世界范围三代虫的寄主情况。三代虫具有很强的寄主特异性,并且在种、属及科等水平上的特异性均有较明显差异;分析同一种寄主上所寄生的三代虫种类之间的关系,显示大部分寄主只寄生一种三代虫,体现出了三代虫很强的寄主特异性。

Host Specificity of Gyrodactylus on Fish

This paper analyzes all of the hosts of the Gyrodactylus around the world so as to provide reference data for the further research work. The results show that: the Gyrodactylus are highly host specificity, and there are significant differences among the levels of species, genus and family. By analyzing the relationship between the species of Gyrodactylus and the same fish, the results show high host specificity i.e. majority of the hosts only have one species of the Gyrodactylus .
