The helminth fauna study of European common brown frog (Rana temporaria Linnaeus, 1758) in the Volga basin

Abstract

In this paper we considered information on the helminth fauna of the European common brown frog (Rana temporaria Linnaeus, 1758) from 10 regions of the Volga basin. This study includes consolidated data of different authors over the last 30 years, supplemented by the results of our own research. There are reliably known finds of 29 species of helminths: Monogenea -1, Trematoda -21, Nematoda -7. Trematodes Gorgodera asiatica Pigulevsky, 1945, Paralepoderma cloacicola (Luhe, 1909, mtc. and nematodes Icosiella neglecta (Diesing, 1851) were observed for the first time in a given host on the territory of Russia and the Volga Basin. Six species of worms make the basis of helminth fauna: nematodes Rhabdias bufonis, Oswaldocruzia filiformis, Neoxysomatium brevicaudatum and Cosmocerca ornata, trematode Haplometra cylindracea and monogenea Polystoma integerrimum. These six species are the most common and widespread parasites of the brown frog. For each species of helminths there is the following information included: taxonomic position, localization, area of detection, biology, definitive hosts, geographic distribution, the degree of host-specificity.

Short communication: An overview of the trematodes fauna of pool frog Pelophylax lessonae (Camerano, 1882) in the Volga Basin, Russia: 1. Adult stages

“…This paper continues a series of publications devoted to the modern characterization of the helminth fauna of amphibians in the Volga basin (Ruchin et al 2009(Ruchin et al , 2016Reshetnikov et al 2013;Chikhlyaev, Ruchin 2014;Chikhlyaev et al 2016bChikhlyaev et al , 2018. This study aimed to present a review on fauna of adult stages of trematodes of a pool frog from Volga basin based on our researches and literature.…”

Helminths of the Eurasian marsh frog, Pelophylax ridibundus (Pallas, 1771) (Anura: Ranidae), from the Shiraz region, southwestern Iran

“…Haematoloechus similis (Looss, 1899) (Digenea: Haematoloechi dae) has been recorded in P. ridibundus in the North East of Iran (Combes & Knoepffler, 1972) and in several species of Pelophylax and Rana in Europe: P. kl. esculentus Linnaeus, 1758 (Bailenger & Chanseau 1954; Bjelic–Cabrilo et al 2009; Chikhlaev et al 2009; Looss, 1899; Odening, 1960; Prokopic & Krivanec, 1974); P. ridibundus (Odening, 1960; Romanova & Matveeva 2010; Saeed et al, 2007) , Rana arvalis Nilsson, 1842 (Odening 1960; Tkach et al 2000); R. temporaria Linnaeus, 1758 (Chikhlyaev & Ruchin 2014; Odening, 1960); Rana sp. (Travassos & Darriba 1930).…”

Ecological analysis of the helminth fauna in Bufo bufo (Amphibia: Anura) from various habitats

“…They are predators for a complex of aquatic and semi-aquatic invertebrate species (rarely of vertebrates). In addition, they are prey for vertebrate predators of a higher trophic level, represented by intermediate, intercalary (mesocercar), additional, paratenic (metacercar) and final hosts for helminthes of different taxa (Sessions & Ruth, 1990;Thiemann & Wassersug, 2000;González & Hamann, 2007;Chikhlyaev & Ruchin, 2014;Chikhlyaev et al, 2016aChikhlyaev et al, ,b, 2018aChikhlyaev et al, ,b, 2019a. Habitat conditions significantly influence the formation of a helminth fauna in amphibians.…”
