[Histological study of the development of Fasciola hepatics in Lymnaea truncatula, L. glabra and L. palustris infested at hatching].
The development of Fasciola hepatica is histologically analysed in Limnaea truncatula, L. glabra and L. palustris infested at hatching with a single miracidium. The development of the redial generations of Fasciola is not affected by the species of snail host but depends on growth of the snail. In snails of size within 2 mm (considered at the day 49 of infestation to 20 degrees C), the rediae show a delay of maturity compared with rediae observed in snails of higher sizes. The distribution of redia 1 of generation 1 should have an influence on growth of the snail host.
