Knemidokoptes mutans (Acari: Knemidocoptidae) in a great-horned owl (Bubo virginianus).
A routine examination of a captive juvenile great-horned owl (Bubo virginianus) revealed bilateral proliferative papillary hyperkeratosis on the feet. Microscopic examination of skin scrapings produced numerous mites identified as Knemidokoptes mutans. This is the first record of this parasite in a great-horned owl. A single dose of ivermectin (200 micrograms/kg) was effective in treatment of this infection.
