Fatal hepatic sarcocystosis in a free-ranging grizzly bear cub associated with Sarcocystis canis–like infection
We describe herein fatal hepatic sarcocystosis in a free-ranging grizzly bear (Ursus arctos horribilis) cub with apicomplexan infection of the liver and brain, both demonstrating 100% homology for Sarcocystis canis and S. arctosi. Fatal hepatic sarcocystosis in dogs has been etiologically associated...
