[Review on non-adaptivity of schistosomes and hosts].

The specificity of schistosomes to hosts and the compatibility of hosts to schistosomes are formed during the long evolution process of them, they are not only related closely to environment but also to other factors such as the heredity of schistosomes and hosts. This paper reviews the non-adaptivity of schistosomes and hosts from the respects of genetics, immunology, cytobiology, molecular biology, and physiology.
