Materials for the helminth fauna of the edible frog Pelophylax esculentus (Linnaeus, 1758) in the Volga basin

Abstract

The work provides information on helminthes of the edible frog Pelophylax esculentus (Linnaeus, 1758) from different regions of the Volga basin on the basis of autopsy of 24 individuals caught in 2005, 2007, and 2010–2015 on the territory of Samara region, Tatarstan and Mari El Republic. The list of parasitic worms includes 16 species from two classes: 14 Trematoda and 2 Nematoda. Among helminthes at the marita stage of Trematodes (11 species) transmitted with food dominated due to the frog’s predation on small aquatic invertebrates and cannibalism. The proportion of larval stages of trematodes (4) and nematodes not circulating on trophic chains (1) was insignificant. Refs 24. Tables 1.
