One snail – three Digenea species, different strategies in host-parasite interaction

摘要: The mostly lab-based studies on snail-trematode interactions should be complemented by research naturally invaded hosts. In this mini-review, three different ways of snail exploitation Digenea larvae are presented. Morphological, physiological and behavioral changes caused parasites in the same infected host – Lymnaea stagnalis differ species-dependent fashion. impact a interaction depends parasite virulence (i.e. induced lost fitness host). pathogenicity varies with survival strategy invader. Sporocyst-born Plagiorchis elegans, which uses individual as first but also second intermediate host, does not disturb processes strongly redia-born Echinoparyphium aconiatum. third species Diplostomum pseudospathaceum, sporocyst-born is more virulent than P. it can modify relax to overwinter snail. data presented demonstrate that successful use arranged ways.
