Two intraperitoneal injections of either infectious or non-infectious rabbit papilloma suspensions actively immunize rabbits against papillomatosis. The capacity of the non-infectious suspensions to immunize is considered as evidence that they contain papilloma virus even though none can be demonstrated by the usual infection test.
两次腹腔内注射传染性或非传染性兔乳头瘤混悬液可使兔主动免疫抵抗乳头瘤病。非传染性混悬液的免疫能力被认为是它们含有乳头瘤病毒的证据,尽管用通常的感染试验都不能证明。
