The action of human gamma globulin on encephalitis viruses was studied. The gamma globulin preparations used in the present study neutralized in vitro definitely Japanese B encephalitis virus, and also, in certain conditions, exhibited a therapeutic effect on experimental JBE infection of mice. Such antiviral activities, however, were not observed in the experiments similarly performed with St. Louis encephalitis virus. Virological significance of the results obtained have been discussed.
