An approximately 1.5-yr-old free-ranging male Eurasian badger (Meles meles) from the eastern part of Austria had macroscopic and microscopic lesions consistent with canine distemper virus infection, including nonsuppurative meningoencephalitis, interstitial pneumonia with accumulation of macrophages in alveoli that contained intranuclear inclusion bodies, vesicular exanthema of the ventral abdomen, and atrophy of lymphoid tissues. Canine distemper virus-antigen was demonstrable in a variety of organs by using immunohistology. In addition, there were widespread areas of fibrosis in the myocardium that were rich in collagen and paucicellular. Because such changes are comparable with sequelae of the acute cardiac form of canine parvovirus (CPV) infection in dogs, it was speculated that this badger may have experienced CPV myocarditis as a cub but that the corresponding antigen or DNA was not detectable due to resolution of the disease.
