Abstract
The helminths of fingerlings of the gray toad Bufo bufo (Linnaeus, 1758) have been studied in some specially protected natural areas (protected areas (PAs)) of the Urals. Only four species of helminths belonging to a Nematoda type are found. The nematodes Oswaldocruzia filiformis and Rhabdias bufonis are common for the studied populations of amphibians. The species composition of geohelminths does not differ in fingerlings or sexually mature amphibians; the infection in adult toads is higher than in fingerlings. The analysis of helminth fauna in the gray toad demonstrated that the nematodes Oswaldocruzia filiformis and Rhabdias bufonis dominate in Bufo bufo in most regions of Russia. The richest species composition of trematodes is noted in the gray toads of Mordovia.
