A head of cattle inoculated with the Fusan strain cattle type of the rinderpest virus was euthanized at 5 day after inoculation and submitted for histopathological examination. Lesions were mainly observed in the mucosal epithelia of the alimentary tract and the lymphoid tissues. In the lips, oral mucosa, tongue and omasum, necrosis of prickle cell layer of mucosal epithelium were observed with syncytia formation with cytoplasmic inclusion bodies. Similar lesions were seen in the muzzle, epiglottis, and eyelid. Single-cell necrosis or focal necrosis of mucosal epithelia were observed from the omasum to the large intestine, from trachea to bronchi, and lactiferous ducts, especially severe from ileocecum to colon. There were also seen syncytia formation and cytoplasmic inclusion bodies. All lymphoid tissues had follicular necrosis, hyperplasia of reticular cells or mononuclear phagocyte system cells, syncytia formation, with cytoplasmic inclusion bodies. The inclusion bodies were also often seen in nuclei. We described characteristic histopathological findings of the lesions in the cattle with the Fusan strain of the rinderpest.
