aspects of the maintenance of the life cycle of fasciola hepatica in lymnaea columella in minas gerais, brazil.fascioliasis is a parasitic disease of domestic ruminants that occurs worldwide. the lymnaeid intermediate hosts of fasciola hepatica include lymnaea columella, which is widely distributed in brazil. a colony of l. columella from belo horizonte, mg, was reared in our laboratory to be used in studies of the f. hepatica life cycle, the intermediate host-parasite relationship and development of an anti-helminthic vaccine. in the first experiment 1,180 snails were exposed to miracidia of f. hepatica ...200212048573
mapping risk of bovine fasciolosis in the south of brazil using geographic information systems.fasciolosis, caused by fasciola hepatica, is an endemic disease of ruminants that occurs in several countries of south america where it can lead to decreased production and fertility and, in severe cases, animal death. although very prevalent, information on the epidemiology of the disease is incomplete in brazil. the objective of the present study was to define the prevalence of f. hepatica in the livers of cattle from slaughterhouses and correlate the data with the animal's origin (climate and ...201020071083
