Materials for the helminthes fauna of pool frog Pelophylax lessonae and European common toad Bufo bufo (Amphibia, Anura) in the Kaluga region

Provides data on fauna of helminths of two species amphibians living on the territory of the Kaluga region. In 2016 г. helminthological full autopsy method investigated 22 specimen of Pool frog Pelophylax lessonae (Camerano, 1882) and 16 specimen of European common toad Bufo bufo (Linnaeus, 1758). Registered 9 species of helminths from two taxonomic groups: Trematoda (5) and Nematoda (4). Six species of parasitic worms was first observed in the studied region. Composition of helminths of Pool frog has 8 species: Trematoda (5) and Nematoda (3). Marita stage and larval stage of trematodes with low values of infestations are dominated. Nematodes are represented by adult stages of a group of geohelminths and biohelminths. High bionematode infection Icosiella neglecta. European common toad 4 species of helminths are detected: Trematoda (1) and Nematoda (3). Oswaldocruzia filiformis and Rhabdias bufonis geonematodes dominate with direct development cycle and a maximum degree of infestation. The role of circulating on trophic relationships, adult stages of trematodes is insignificant.
