Summary. The analysis of the epizootological situation on the main anthropozoonoses of invasive etiology of commercial animals and fish in the Republic of Sakha (Yakutia) was carried out. The foci of trichinosis were established throughout the territory of the republic. The main carriers of the disease are wolves (48.4%) and brown bear (42.7%), the minor ones are foxes (3.5%), polar foxes (7.19%) and other. The natural focus of alveococcosis under conditions of Yakutia is supported by polar foxes and rodents. Polar foxes provide wide distribution of parasite eggs. The larval stage of echinococcosis was registered among reindeer (17.2%) and elks (76.2%); adult tapeworms are found in wolves (61.1%). Alveococcus were found in foxes (5.5%) in central and mountain-taiga zones. The plerocercoids of broad tapeworm were registered in 89% of burbot, 57.6% of pike, 22.9% of perch, 15.2% of ruff and 13.6% of tugun on the middle course of Lena river. Plerocercoids of gull-tapeworm were found in such semi-anadromous fish in the lower course of fishing rivers as vendace (14%), omul (22.3%), broad whitefish (15.7%), muksun (8.1%). Invasion of wild animals and white salmon was not registered, but the infectiousness by Diphyllobothrium dendriticum was found in 46.1% of common gulls. In the middle course of Lena the anthropurgic focus of broad tapeworm Diphyllobothrium latum was discovered. In the lower courses of fishing rivers the natural focus of gull-tapeworm was detected, which is indicated by high degree of infection by the disease in local population. The main factor of the transfer of the invasive agent is the traditional eating of insufficiently sterilized salted fish.
