作者曾将 １型副流感病毒（ＰＩＶ１）血凝素－神经氨酸酶和融合蛋白基因替代ＰＩＶ３反基因组ｃＤＮＡ中的相应基因，制备重组嵌合 ＰＩＶ３－ＰＩＶ１病毒，称为 ｒＰＩＶ３－１。 ｒＰＩＶ３－１在细胞中和仓鼠体内的生长特性类似于野型病毒，并具有ＰＩＶ１的主要保护性抗
The authors prepared a recombinant chimeric PIV3-PIV1 virus called rPIV3-1 by replacing the corresponding gene in the PIV3 antigenomic cDNA with the hemagglutinin-neuraminidase and fusion protein type 1 parainfluenza virus (PIV1). The growth characteristics of rPIV3-1 in cells and in hamsters are similar to wild-type virus and have the major protective anti-PIV1
