单词 | fasciola |
释义 | fasciolan. 1. Zoology. Any of the liver flukes (parasitic trematode flatworms) of the genus Fasciola (family Fasciolidae), the members of which feed and reproduce in the liver and biliary tract of sheep, cattle, and other mammals (including humans); esp. the fluke F. hepatica, which is a major cause of disease in sheep (cf. fascioliasis n.). Also (in form Fasciola): the genus itself (frequently as a modifier).These flukes have a complex life cycle that includes an intermediate stage of development (from miracidium to cercaria) in pond snails (genus Lymnaea). Mammals become infested by ingesting vegetation or food contaminated with parasites in the metacercarial stage. ΚΠ 1783 J. Barbut Genera Vermium I.
