Helminths of large predators in Central forest state natural biosphere reserve

The helminthoovoscopy investigation of feces of large carnivores (brown bear, grey wolf and lynx) was performed. The invasion’s extensiveness for brown bears was 54.4%. Baylisascaris transfuga was dominant (42.6% of samples). Four species of helminthes have been revealed in the grey wolf. Eggs of parasites were found in 80% of samples. Thominx aerophilus and Spirometra erinacei-europaei prevailed, the last being the zoonotic disease. Eggs of helminthes were detected in 47,05% of lynx's feces. Spirometra erinacei-europaei and Hepaticola hepatica dominated. The diet plays a significant role in the helminthes’ composition of the carnivorans studied.
