[Predatory terrestrial mammals--the definitive hosts of Diphyllobothrium klebanovskii].

To clarify the definitive hosts of Diphyllobothrium klebanovskii in the Far East, 2198 individuals of 18 terrestrial predatory and omnivorous mammal species were surveyed. It was established that 47.1 +/- 8.56% of brown bears, one of the two dissected black bears, 1.7 +/- 1.2% of wolves, 1.6 +/- 0.71% of dogs, 0.3 +/- 0.14% of American minks and 2.8 +/- 2.75% of pigs were invaded by a tapeworm. Obligatory hosts of the parasite were brown and black bears, and the remaining species were optional hosts of limited significance in maintaining parasite circulation.
