The entrance into host tissues by the cercaria of the digeneanDiplostomum spathaceum and the parasite's migration to the eyes of the fish host (post-penetration larvae) were studied by scanning and transmission electron microscopy at the ultrastructural level and by a radiometric assay in experimentally infected rainbow trout (Oncorhynchus mykiss). It was demonstrated that cercariae penetrated the host surface at several sites, although the major site involved the gill region. This observation… CONTINUE READING
