【Abstract】 The paper is a systematic study on the freshwater molluscs transmitting parasitic diseases in China and have also discussed the relation between parasites and molluscs.There are al- together 67 species and subspecies (belonging to 26 genera,12 families,2 classes) that serve as the intermediate hosts of parasites harming hum an and animals,65 species and subspecies of them being the fresh and brackish water snails and only 2 species the freshwater bivalve.It is shown that the freshwater snails are important molluscan vehicules of infectious diseases.The parasites have a specificity in choosing their intermediate hosts.For example,the blood fluke enly selects Oncomelania hupensis as its intermediate host;the lung flukes of pulmonary Type choose some ceritheacean snails and those of extrapulmonary Type choose some small hydrobiid snails which distribute over hills,medium and high mountains in South China.Excepting the land snails,Angiostrongylus cantonensis also chooses 34 species of the freshwater snails be- longing to 6 families as its intermediate host.更多还原
