Demodicosis in a Free-Ranging Eurasian Brown Bear (Ursus arctos arctos) Cub in the Endangered Cantabrian Population, Spain

A free-living female Cantabrian brown bear (Ursus arctos arctos) cub severely affected by mange in Asturias (northern Spain) represented the first report of demodicosis for this species. After antimicrobial, antiparasitic, anti-inflammatory, and analgesic therapy it recovered and was released back into the wild to the eastern Cantabrian brown bear subpopulation.
