我国内陆水体单殖吸虫的宿主特异性分析

报道我国内陆水体单殖吸虫的宿主特异性的研究。研究表明单殖吸虫有很强的宿主特异性，但不同种类的特异的有很大的判别。从目前已有的记录来看，６０％以上的单殖吸虫中只有１种宿主，约７５％的单殖吸虫的宿主仅为１属，超过９７％的单殖吸虫的宿主在１科之内。没有１种单殖吸虫可生于超过３个料的宿主中，但大钩指环虫可在２３属３３种宿主中寄生。在科和发放持异性水平，以锚首虫科和指环虫科单殖吸虫的特异性较强，三代虫科次之

The host-specificity of monogeneans in inland waters of China

The host specificity of monogeneans in inland waters of China was studied.The great specificity and the obvious difference of specificity among four major families of monogeneans were observed.According to published records,more than 60% species of monogeneans were found only on 1 host species,and about 75% species on 1 host genus,over 97% species on 1 host family.No monogenean species is able to parasitize on hosts over 3 families,however,the host tree of the monogenean species Dactylogyrus magnihamatus covers 23 genera or 33 species.At the levels of host family or genus,the monogeneans of Ancyrocephalidae and Dactylogyridae have greater host specificity than Gyrodactylidae and Diplozoidae.Deplozoidae has the lowest specificity in the four families.At the level of host species,no significant difference of host specificity was observed among the four families.
