This study was undertaken to clarify the histopathological changes of pigs naturally infected with hog cholera. Vascular cuffing of the brain was observed in about 97% of the natural cases and all of the experimental cases. Electron microscopic findings on cuffed blood vessels of the brain were endothelial cellular degeneration and infiltration of pleomorphic lymphoid cells. In the rabbits dosed with tissue suspension of the lymphoid organs and isolated hog cholera virus, high body temperature and vascular cuffing of the brain were more significant in pre-injected cases with indian ink
