Summary

Severe reaction was sen by sukutaneous iniion with cxncentraJ and heatinactivated PrV antigen in lower eyelid of swine, This reaction was verified as delayedtype hypersensitive reaction by hisetho1ogical changes. Nonepo6ed oc’ntrol pigs did not react to the viral and cellular antigens at all. The correlation among serum naq neutralization, Jiffision, and skin test was analysed, The result indicated that the sensitivities of the latter two ts were pretty high and similar to each other. The antigens obtained by treating the infested cells with proo1ytic enzyme were suituble for microimmunediffusion test.
