Three cases of bovine malignant catarrhal fever (MCF) were reported. Histological examination disclosed mucosal lesions which were intensively affected at .zpperalimentary canal and characterized by necrosis of mucosaJ layer with erosion and ulcerationas well as mononuclear cell infiltration at propria and submucosa, systemic vascular lesionscharacterized by polyarteritis with mononuclear cell proliferation at adventitial region, focal fibrosis of muscular tissues with histiocytic cells, mononuclear cell infiltration atinterstitial tissues of parenchymatous organs of the whole body, capillarization at substancia propria of the corneas, destruction of mature lymphocytes in lymphatic tisstzes, andnon-suppurative encephalitis. Electron microscopy on intranuclear structures of parietalcells of the abomasum revealed granular or lattice-like structures whiclt were consideredas products of metabolic disorder due to viral affection. Discussion was made on somediseases similar to MCF in clinico-anatomical features, and the significance of systemichistopathologic examination was stressed.
