[The elk--the intermediate host of Echinococcus granulosus in Yakutia].

The Yakut elk is an obligatory intermediate host of E. granulosus (Batsch, 1786). In this region, a mixed focus of hydatid echinococcosi causative agent with a dog-elk-dog pattern of circulation was revealed in the presence of a natural focus where the circulation pattern was wolf-elk-wolf.
