Abstract

Intraperitoneal infection with the avirulent A7(74) strain of the alphavirus Semliki Forest virus (SFV) induces an immune mediated demyelinating encephalomyelitis. The blood and brain virus titres, the serum antibody titres and the histopathological changes in the brains of normal mice and mice immunosuppressed with 5.0 or 8.0 Gy total body irradiation (TBX) were determined. SFV infection of immunosuppressed mice resulted in persistently high blood and brain virus titres, neuronal pycnosis, paralysis and death. No demyelination or central nervous system (CNS) inflammatory response occurred in these immunosuppressed mice despite high and persistent brain virus titres. The CNS inflammatory res..
