Contribution to the knowledge of infectivity of Fasciola hepatica adolescariae after their passage through the digestive tract of white mice.
The study of infective elements of Fasciola hepatica which passed through the digestive tract of white mice revealed that those adolescariae (transitive adolescariae) (Table 1), which were not visibly damaged or possessed a more or less digested outer cyst wall, remained infective. The mice infected with transitive adolescariae harboured higher number of trematodes in the livers than those infected with infective elements which had not previously passed through the digestive tract of the definitive host.
