One captive male capercaillie (Tetrao urogallus) was found dead on December 1993 at the breeding center of capercaillie in Catalonia, Spain. The bird was emaciated and, at necropsy, had numerous nodules of various sizes subcutaneously in the cervical region, pleura, lungs, liver, spleen, and mesentery. Microscopic examination revealed granulomatous lesions with central caseous necrosis, epithelioid cells, giant cells, and few lymphocytes in all affected organs. Numerous acid-fast bacilli were demonstrated in the tubercles with Ziehl-Nielsen stain.
