ABSTRACT

The present work investigated the penetration pathways of Fasciola hepática (Linnaeus, 1758) into the hepatopancreas of Lymnaea truncatula (Muller, 1774) and Lymnaea cubensis (Pfeiffer, 1839), two mollusks obtained from Fasciolosis endemic areas in Russia and Mexico, respectively.
The larval trajectory showed dissolution of intercellular substance and deformation of epithelial cells of mollusk’s tissues. Cytological changes in the ductal epithelium of the digestive gland and in the connective tissue of hepatopancreas were found. Some differences in the penetration and damage pathways in the two species of mollusks studied were observed; thus highlighting the differences in the environmental conditions prevailing in each geographic area.
