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.

“…Appareil reproducteur mâle : testicules intercaecaux disposés en diagonale, postacé- Notre espèce n'est assimilable à aucune espèce néarctique, néotropicale ou paléarctique connue ; en particulier elle se distingue de Haematoloechus variegatus (Rudolphi, 1819) Looss, 1899. par son ovaire lobé, la présence de vitellogènes dans le champ post-testiculaire, et plusieurs caractères mineurs. Signalons d'ailleurs que si H. variegatus a été signalé en Afrique par Joyeux et Baer, 1928, chez une Rana de Haute-Guinée, cette mention non accompagnée de dessin est fortement mise en doute par Odening, 1958, et par Batciivarov et Bourgat, 1974 En ce qui concerne les espèces d 'Haematoloechus de la zone Ethiopienne, notre espèce se distingue (tabl.

Étude comparative des Polystomes (Monogènes) de Ranidés (Anoures) du Sud Togo Description de Polystoma togoensis n. sp. par Robert Bourgat * Collaboration technique Sena Agbalo Résumé. -Six Ranidae (Anura) du Sud Togo livrent chacun un Polystome. Respective¬ ment Rana galamensis : Polystoma galamensis ; Phrynobatrachus accraensis : Polystoma ragnari ; Hylarana albolabris : Polystoma perreti ; Ptychadaena oxyrhynchus : Polystoma prudhoei ; Ptychadaena maccarthyensis : Polystoma baeri ; Ptychadaena hylaea : Polystoma togoensis.L'étude de séries montre que P. togoensis n. sp. diffère de P. baeri essentiellement par l'en¬ semble des dimensions et la silhouette de l'appareil digestif ; arguments morphologiques et biogéographiques s'ajoutent pour justifier la création de l'espèce P. togoensis.Chaque population de Polystome ne parasite qu'une espèce d'Amphibien ; de deux hypothèses explicatives envisagées, écomorphose collective ou radiation adaptative, la seconde rend mieux compte des observations et représente avec plus de réalisme la dynamique du phénomène.
“…Parmi les distomes pulmonaires dAmphibiens, ceux appartenant à la famille des Haematoloechidae Odening, 1964 et au genre Haematoloechus Looss, 1899 sont particulièrement abondants. Les espèces de ce genre sont largement distribuées, particulièrement dans les régions paléarctique, holarctique et neotropicale (Cort, 1915;Dobbin, 1957;Odening, 1958;Yamaguti, 1971;Prudhoe & Bray, 1982).…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
