Results of testing for highly pathogenic avian influenza virus in red foxes (Vulpes vulpes), Germany. A) Microscopic findings in the brain of an influenza A(H5N1) virus‒infected red fox showing a lymphocytic to histiocytic perivascular encephalitis (hematoxylin and eosin stained, scale bar = 50 μm). B) Immunohistochemical demonstration of influenza A virus nucleoprotein in neurons (arrows) and glial cells (arrowheads) in the cerebrum of a virus‒infected red fox (avidin biotin complex method, scale bar = 20 μm).
