摘要
为获得狂犬病病毒和犬细小病毒的二联疫苗,本研究运用分子生物学技术在狂犬病病毒基因组的G基因与L基因之间插入犬细小病毒VP2基因,通过反向遗传操作系统拯救获得了含犬细小病毒VP2基因的嵌合狂犬病病毒HEP-Flury(VP2),并研究了该病毒的生物学特性。结果表明,嵌合狂犬病病毒HEP-Flury(VP2)可以在BHK-21细胞上稳定繁殖,在传代10次后,外源基因VP2能高效表达;以HEP-Flury(VP2)免疫小鼠,可以诱导免疫小鼠产生抗狂犬病病毒和抗犬细小病毒的抗体。
To obtain a bivalence vaccine against canine rabies virus and canine parvovirus, a chimeric rabies virus expressing canine parvovirus VP2 protein was generated by the technique of reverse genetics. It was shown that the chimeric virus designated as HEP-Flury（VP2） grew well on BHK-21 cells and the VP2 gene could still be stably expressed after ten passages on BHK-21 cells. Experiments on the mice immunized with the chimeric virus HEP-Flury（VP2） demonstrated that specific antibodies against rabies virus and canine parvovirus were induced in immunized mice after vaccination with the live chimeric virus.
