Mechanisms in the pathogenesis of post-infectious vaccinia virus encephalomyelitis in the mouse

After intracranial replication of a neurotropic strain of vaccinia in mouse brain, analysis of the purified virus preparation reveals the presence of at least one host protein on the virus which was identified as the myelin basic protein. Vaccinia virus Elstree, a dermotropic virus may substitute for complete Freund's adjuvant (CFA) in inducing experimental allergic encephalomyelitis (EAE). Guinea pigs challenged with virus-myelin emulsions without CFA developed clinical and histological signs of EAE.
