The following reverse zoonosises have been registered in the territory of the Yamalo-Nenets Autonomous Okrug (YNAO): trichinellosis of wild animals, echinococcosis, diphyllobothriasis, beef tapeworm, trichinellosis, and opisthorchiasis of carnivores and humans. Fur-bearing animals have nematodosises, that pose a danger to humans - toxocariasis, uncinariasis, trichinellosis; cestodiasis - diphyllobothriasis, dipylidiosis, echinococcosis; trematodiasis - opisthorchiasis and metorchsis, with EI of 0.7-4.3%. Invasiveness of dogs and cats by helminth (toxocariasis, uncinariasis, opisthorchiasis, diphyllobothriasis, dipylidiosis, and alveococcosis) in the territory of YNAO amounts to 1.6-22.3%. The research results are of social and economic significance because they aim to prevent critically dangerous parasitoses in animals and humans. It is necessary to continue research and further monitor the parasitological situation to adjust preventive and therapeutic measures further.
