Abstract

Systemic idiopathic amyloidosis was described in four captive badgers (Meles meles). Two animals (B1 and B2) were not enrolled in any trial, while animals B3 and B4 took part in a vaccine efficacy study and had been challenged with Mycobacterium bovis. A full set of tissues was collected and processed routinely for histopathological, immunohistochemical and ultrastructural studies. Splenomegaly was found in three out of four animals. Histopathological evaluation revealed congophilic, permanganate-resistant systemic amyloid deposits in the tissues of all badgers. Animals B2 and B4 displayed a marked granulomatous response to amyloid within the spleen. Animals B1 and B2 also displayed clinicopathological findings suggestive of chronic kidney disease. Ultrastructural examination identified peculiar star-shaped arrays of amyloid. Immunohistochemical studies were unrewarding. Systemic amyloidosis should be considered among the differentials of wasting in captive badgers.
