Authors:Y Yoshikawa  K Yamanouchi  T A Sato  S Katow  M Ito
Abstract:The Niigata-1 strain isolated from a patient with subacute sclerosing panencephalitis (SSPE) was inoculated intracerebrally into ferrets. Neurological signs developed in about 1 week in most of the animals. Histopathological examinations of the central nervous tissues revealed degenerative lesions in the parenchyma of the brains and inflammatory reactions predominantly in the meninges and choroid plexus. Virus antigen was demonstrated mainly in the nerve cells by immunofluorescent staining. The results indicated high affinity of the Niigata-1 strain to the nerve cells. In contrast, the Mantooth strain of SSPE virus in cell-free state did not exhibit neurovirulence in ferrets.
