Abstract

Swiss mice injected subcutaneously with suspensions of spleen cells or an extract of spleens from mice infected with Friend virus develop resistance to subsequent intravenous inoculation of Friend virus. A single injection of either Friend virus or Friend cells induces resistance. Immunized mice display resistance when challenged 6 months after immunization and survive for at least 20 weeks after infection. Neutralization tests indicate that serum, but not lymphoid cells of resistant animals, can neutralize Friend virus. In vitro neutralization tests indicate that residence of virus within the peritoneal cavity of immune mice for 1 h sharply reduces the infective titer of the virus.

摘要

皮下注射感染了Friend病毒的小鼠脾脏细胞悬液或脾脏提取物的瑞士小鼠,对随后静脉注射Friend病毒产生抗性。单次注射Friend病毒或Friend细胞均可诱导抗性。免疫小鼠在免疫6个月后受到攻击时表现出抗性,并在感染后存活至少20周。中和试验表明,抗性动物的血清而非淋巴细胞能够中和Friend病毒。体外中和试验表明,病毒在免疫小鼠腹腔内停留1小时会大幅降低病毒的感染滴度。
