Abstract

The records of helminth fauna from grass frogs Rana temporaria Linnaeus, 1768 of Republic of Mordovia are provided. 16 helminth types have been discovered: 1 Monogenea, 11 Trematoda, and 4 Nematoda. Dominating in quantity of types the adult and larval trematodes are characterized by a lower infeсtion rate and beong to rare parasites of the specific host. Geonematodes Rhabdias bufonis (Schrank, 1788) and Oswaldocruzia filiformis (Goeze, 1782) are background parasites with a high infection rate found in all frogs; nematodes Cosmocerca ornata (Dujardin, 1845), trematodes Haplometra cylindracea Zeder, 1800 and Pleurogenes claviger (Rudolphi, 1819) occur more rarely. The differences of single amphibian populations are determined based on various structures of trematodes and depend on biotopical conditions.
