Abstract
The results of long-term (1993–1996, 1999–2007) monitoring study of the species composition of trematode larvae parasitizing in their first intermediate hosts of Lymnaea (Stagnicola) saridalensis from Chany Lake, Western Siberia are presented. It was established that 50% of L. saridalensis population were infected with 11 trematode species of parthenitae and cercariae belonging to the families: Plagiorchiidae, Echinostomatidae, Diplostomatidae, Strigeidae, Notocotylidae, Schistosomatidae. Double infections were detected in 0.8% of infected snails. The trematodae of Plagiorchiidae family dominate in larval community. There is a very similar spectrum of the most common species of cercariae still stable during the period of study. Cercariae P. mutationis and P. multiglandularis are registered for the first time in Lymnaea saridalensis snail in West Siberia.
