Infestation of amfibians from Pelophylax Esculenta (Amphibia) complex with the trematode species Codoncephalus Urniger (Strigeida) in Central Codrii in the Republic of Moldova

Abstract

The paper presents data on amphibians’ trematodes infestation from Pelophylax esculenta complex (Amphibia, Anura) in natural and anthropized ecosystems of Central Codri forest from the Republic of Moldova. The helminthological researches of amphibians were accomplished for the first time in the Republic of Moldova. As result, the infestation of Pelophylax complex species (Pelophylax ridibundus, P. lessonae, P. esculentus) with trematodes from family Diplostomidae (Codonocephalus urniger, Rudolphi, 1918 was established. For each species there were established: taxonomic status, including synonyms, the hosts, the location in organs, the geographic spreading, etiology and biologic cycle. There are also mentioned the amount of collected material, the morphologic description of the species, original figures and pictures, the level of infestation depending on age, sex and ecosystem.
