摘要:
兔出血症病毒2型毒株于2020年在我国首次发现并报道,目前尚无有效的疫苗可用于对该毒株的防控。针对我国兔出血症病毒2型SC毒株VP60蛋白,构建获得表达该毒株VP60蛋白的重组杆状病毒rBAC-RHDV2-VP60。以rBAC-RHDV2-VP60为疫苗毒种,接种昆虫细胞,表达获得重组VP60蛋白。以氢氧化铝胶为佐剂制成RHDV2 SC株VP60基因工程疫苗,结合前期制备的传统RHDV型WF株VP60基因工程疫苗,分别免疫2~3月龄健康易感兔,1.0 mL/只;免疫后21 d,检测2种疫苗分别对国内RHDV2流行株和传统RHDV毒株的免疫保护力。结果显示,用SC株攻毒,免疫RHDV2 SC株VP60基因工程疫苗的家兔,免疫组无死亡,而免疫生理盐水的对照组全部死亡;免疫传统RHDV WF株VP60基因工程疫苗的家兔,免疫兔6/10死亡,对照组兔全部死亡;用WF株攻毒,免疫RHDV2 SC株VP60基因工程疫苗的家兔,免疫组死亡7/10,而免疫生理盐水的对照组全部死亡;免疫传统RHDV WF株VP60基因工程疫苗的家兔,免疫兔无死亡,对照组兔全部死亡;提示传统RHDV型WF株疫苗不能对国内流行毒株RHDV2 SC毒株产生有效的免疫保护,RHDV2 SC株VP60基因工程疫苗也不能对国内传统RHDV毒株产生有效的免疫保护,两型毒株间交叉保护作用较低。本研究中针对我国流行RHDV2 SC毒株研制的基因工程疫苗对有效预防和控制国内流行的RHDV2将发挥重大作用。
