[Infection and invasion of humans in the Yamal Peninsula].

The helminthic fauna of vertebrates in the Yamal peninsula consists of 61 species: of them 2 species are monogenic, 6 are trematodes, 29 are cestodes, and 24 are nematodes. Twelve species of the 4 are antroponoses and 8 are zoonoses which may parasite on human beings. Human infection with some zoonoses is due to local habits of eating raw or undercooked meat of wild animals, domestic deers, and fish. These helminthic diseases include trichinosis, taeniasis, opisthorchiasis, diphyllobothriasis. On contacting with dogs and Arctic foxes, the population is infected with echinococciasis, alveococciasis, toxoplasmosis. The foci of brucellosis, anthrax, tularemia, leptospirosis, rickettsioses, rabies, and toxoplasmosis were notified in the Yamal peninsula. Intensive migration of the population contributes to the importation of new species of causative agents to the peninsula and to the deterioration of the situation of endemic invasions and infections. Thus, in-depth study of parasitic and natural focus-related diseases in this region becomes partially urgent now.
