Data on the helminths of edible frog Rana esculenta Linnaeus, 1758 (Anura, Amphibia) in
Middle-Volga region. – Chikhlaev I.V., Fayzulin A.I., and Zamaletdinov R.I. – Data on the
helminths of edible frog (Rana esculenta Linnaeus, 1758) from the Middle-Volga region are resulted
for the first time. These data were obtained during dissection of 15 specimens gathered in
Tatarstan Republic and the Samara region in 2007 – 2008. The specific composition counts 11
species, namely: Trematoda – 10, Nematoda – 1. Among the helminths the adult trematoda forms
transmitting with food (9 species) predominate, which is due to eating water invertebrates and
young amphibians. The fraction of the larval forms of helminths (1) and geonematodes not circulating
through trophic chains (1) is insignificant.
Key words: edible frog, Rana esculenta, helminth, trematoda, nematod.
