    Abstract:
    The pathogenic characteristics of tick-borne encephalitis (TBE) virus strain (Oshima 5-10) isolated from a sentinel dog in Hokkaido, Japan, was compared by use of a mouse model with several inoculation routes to other strains of TBE virus (the Far Eastern subtype; Sofjin strain and the Western subtype; Hochosterwitz strain) and TBE complex virus (Langat virus; TP-21 strain). The degree of neuroinvasiveness of the strains in mice subcutaneously (s.c.) inoculated was Sofjin equaled Hochosterwitz which was greater than Oshima and TP-21, respectively. Neurovirulence, as determined after intracerebral inoculation was Sofjin > Oshima = Hochosterwitz > TP-21. Virus replication in the brains of mice s.c. or intracerebrally inoculated with Oshima strain was slower and of lower titer than that of Sofjin strain. Histopathological findings indicated that subarachnoid infiltration of mononuclear cells prior to necrosis of the cerebrum was characteristic in Oshima strain. These findings indicated that the Oshima strain possessed a pathogenic potential common to TBE viruses and is less virulent for mice as compared with the two other TBE strains examined.
