Photomicrographs of brain and spinal cord sections from cats with non-suppurative meningoencephalomyelitis and plausible staggering disease. a) Inflammatory infiltrates (arrows) located in the cerebral grey matter and meninges in cat No. 1978a. b) Higher magnification of perivascular inflammatory infiltrate in a) showing a mixed population of lymphocytes, histiocytes and plasma cells. c) Degenerative neuron (n) surrounded by glial cells (*) and perivascular inflammatory infiltrate (arrow) in brain stem from cat No. 1993. d) Glial proliferations in the hippocampus (*) in cat No. 2015. e) Perivascular infiltrates following vessels in grey (g) and white (w) matter in spinal cord from the same cat as depicted in a). f) Large inflammatory infiltrate (arrows) located in the meninges between the cerebellum and brain stem with additional perivascular inflammatory infiltrate present in brain stem (upper right corner) in cat No. 1978b. In a), e) and f) bar = 200 µm, in b) and c) bar = 50 µm and in d) bar = 100 µm. Haematoxylin and eosin stain
