This study was conducted to investigate helminth parasites of Eurasian Marsh Frog (Pelophylax ridibundus) from Bingöl province, in 2012. A total of 42 specimen were collected from six localities from Bingöl (Eastern Anatolia, Turkey) Twelve helminthes species were found from the collected samples: Haematolechus breviansa, Diplodiscus subclavatus Opisthioglyphe ranae, Pleurogenoides medians, Gorgodera cygnoides, Gorgoderina vitelliloba, Cosmocerca ornate, Rhabdias bufonis, Oxysomatium brevicaudatum, Eustrongylides excisus, Oswaldocruzia filiformis and Acanthocephalus ranae. Several studies on helminth fauna of Eurasian marsh frogs (P. ridibundus) have been published by different researchers and localities. All parasite species have been recorded previously but this study is the first helminthological study for host-frog from Bingöl province, Turkey.
... That rich system in northern Iraq, however, did not seem to support infections with monogenetic trematodes, cestodes or acanthocephalans. In Uzbekistan, R. ridibunda was found infected with 10 species of trematodes, 3 species of cestodes, 9 species of nematodes, and 4 species of acanthocephalans whose identity was not available (Ikromov et al., 2004). ...
... They are rare in the helminth fauna of R. arvalis. Despite the high volume of materials and the long period of study, cestodes and acantocephalae were not found in R. arvalis in Western Siberia, even through they have been registered in this species and other representa tives of the genus Rana in other parts of the habitat (Poland (Okulewicz et al., 2013), Turkey (Dü en and Öz, 2006), and Uzbekistan (Ikromov et al., 2004)). The relatively depleted fauna of helminths may be associated with the northern location of the studied territories, whereas the taxonomic diversity of helm inths in the genus Rana is higher in areas lying south wards (Muzzall, 1991;Ikromov et al., 2004;Dü en and Öz, 2006). ...

The composition of helminths and infestation indices of two frog species of living in Western Siberia (Rana arvalis (n = 1082) and Rana amurensis (n = 33)) have been studied. Nine helminth species, including four nematodes and five trematodes, have been found. The following species were dominant and infected both frog species: nematodes Rhabdias bufonis, Oswaldocruzia filiformis, and Cosmocerca ornata and trematodes Haplometra cylindracea. The moor frog also hosted Dolichosaccus rastellus, Opisthioglyphe ranae, Pharingostomum cordatum (larvae), Parastrigea robusta (larvae), and Neyraplectana schneideri. The moor frog was characterized by higher species richness and diversity of helminths than the Siberian tree frog. The overall rates of helminth infestation have been the same in the moor frog and the Siberian tree frog. The invasion extensity was 85-100%; the index of abundance was 5.2-27.5. Differences in infestation rates of certain species by helminths were due to the biological peculiarities of the frog species.

Of the 17 species of anurans (Amphibia) known from 6 families in Turkey, 12 species were reported
infected with helminths including monogenean, digenean, cestode, nematode, and acanthocephalan parasites. The
17 species are Bufo bufo (Linnaeus, 1758), Bufo verrucosissimus (Pallas, 1814), Bufo (Pseudepidalea) viridis Laurenti
1768 (Bufonidae), Bombina bombina (Linnaeus, 1761) (Discoglossidae), Hyla arborea (Linnaeus, 1758), Hyla
savignyi Audoin, 1827 (Hylidae), Pelobates fuscus (Laurenti, 1768), Pelobates syriacus (Boettger, 1889)
(Pelobatidae), Pelodytes caucasicus Boulenger (1896) (Pelodytidae), Pelophylax bedriagae (Camerano, 1882),
Pelophylax ridibundus (Pallas, 1771) (formerly known as Rana ridibunda), Pelophylax caralitanus (Arikan, 1988),
Rana camerani (Boulanger, 1886), Rana dalmatina Bonaparte, 1838, Rana holtzi Werner, 1898, Rana macrocnemis
Boulanger, 1885, Rana tavasensis Baran and atatür, 1986 (Ranidae). Helminths were not reported in B.
verrucosissimus, H. savignyi, P. fuscus, P. bedriagae, and P. caralitanus. The most heavily infected host was P.
ridibundus. This host is known to be an aggressive feeder and highly adaptable to a wide variety of habitats and diet.
Host species with restricted distribution and limited diet show very light infections, if any. Some of the reported
hosts extend their range of distribution outside of Turkey where they were found infected with the same and often
with other populations of parasites reflecting the varied invertebrate fauna. The overall diversity of parasite
populations per each host species is clearly markedy greater than what this report suggests if the host populations
in their total range of distribution are taken into account. Parasites and hosts do not know political borders.

Fifty-three marsh frogs, Rana ridibunda, that were collected during the period from 1998 to 2004 from 4 different regions
of Turkey and variable extended localities, were examined for helminths. As a result of our study 16 species of metazoan parasites were
found. These included 9 Digenea, 4 Nematoda, 2 Acanthocephala and 1 Hirudinea. Pleurogenoides stromi, Cosmocerca ornata, Neoxsyomatium
brevicaudatum, Oswaldocruzia filiformis, Eustrongylides excicus and Centrorhynchus spp. were detected. This is the first
time that Rana ridibunda has been reported in Turkey.

Between 2000 and 2022, a study in Uzbekistan examined 1822 amphibians (624 Bufotes genus, 1198 Pelophylax genus) to assess helminth biodiversity. Species studied included Perrin's Green Toad, Pewzow's Toad, Turan Toad, Terentiev Water Frog, Pelophylax sp., and Pelophylax terentievi × Pelophylax sp. hybrid. The study revealed the presence of 66 species of parasitic helminths, including those from the classes Cestoda, Trematoda, Acanthocephala, and Nematode, in Uzbekistan's amphibians. Notably, the genus Bufotes and the genus Pelophylax were newly identified as hosts for 14 helminth species in the country. The biological diversity of amphibian helminths in Uzbekistan consists of 66 species, with varying distribution: 42 in the NorthEastern region, 40 in the Eastern region, 38 in the Southern region, 25 in the Central region, and 17 in the NorthWestern region.

this article summarizes the results of research on the helminth fauna
of amphibians and reptiles in the period 2000-2020. In total, 154 species of helminthes were found in amphibians and reptiles.
The current distribution of sparganosis in Europe is reviewed and a molecular phylogenetic concept of species in the genus, which reflects their geographical distribution of the parasite is proposed. The sympatric presence of two species in Europe, region-specific Spirometra erinaceieuropaei and Asian-Oceanic S. mansoni is detected for the first time. ABSTRACT Sparganosis is a relatively neglected food-and waterborne disease caused by species of the tapeworm genus Spirometra the global distribution of which has not been sufficiently recognised. Known mainly as a zoonosis of East Asia, its species are native to all inhabited continents including Europe. Spirometra has been reported from numerous wildlife species from 17 European countries and a critical review confirmed 17 autochthonous and 8 imported human clinical cases. We present the first molecular evidence of the coincident presence of two species in Europe and review the current distribution to raise awareness of the parasite in this region. Spirometra erinaceieuropaei is restricted to Europe and S. mansoni represents a lineage distributed mainly across Asia and Oceania that reaches Europe. The parasite is common in Eastern Europe and its distribution has potential to expand along with its invasive or migrating mammal hosts, spreading the risks of human infection.
