    • The present invention provides a novel infectious cDNA clone of porcine reproductive and respiratory syndrome virus (PRRSV), particularly for PRRSV strain VR2385; an improved DNA-launched reverse genetics system for PRRSV; infectious chimeric PRRSV viruses generated through DNA shuffling; modified live- attenuated virus vaccines (MLV) using DNA shuffled chimeric viruses; chimeric viral proteins produced through shuffled chimeric viruses; PRRSV antigens and subunit vaccines based on shuffled chimeric viral proteins; and method of producing broadly protective PRRSV vaccines using DNA shuffling techniques. Particularly, the present invention provides infectious chimeric viruses generated by DNA shuffling of the GP5 genes of genetically distinct strains of PRRSV; modified live-attenuated vaccines comprise infectious chimeric viruses containing the shuffled GP5 genes and/or other shuffled PRRSV proteins (such as GP2, GP3, GP4, M, and non-structural proteins); broadly -protective subunit vaccines comprising PRRSV chimeric shuffled GP5 protein and/or other shuffled PRRSV proteins (such as GP2, GP3, GP4, M, and non-structural proteins).
    • 本发明提供猪繁殖与呼吸综合征病毒(PRRSV)的新型感染性cDNA克隆,特别是PRRSV株VR2385的感染性cDNA克隆; 用于PRRSV的改进的DNA推出的反向遗传学系统; 通过DNA改组产生的感染性嵌合PRRSV病毒; 使用DNA混洗嵌合病毒的改良活减毒病毒疫苗(MLV); 通过混洗嵌合病毒产生的嵌合病毒蛋白; 基于混洗嵌合病毒蛋白的PRRSV抗原和亚单位疫苗; 以及使用DNA改组技术生产广泛保护性PRRSV疫苗的方法。 特别地,本发明提供了通过遗传上不同的PRRSV菌株的GP5基因的DNA改组产生的感染性嵌合病毒; 修饰的活减毒疫苗包括含有洗牌的GP5基因和/或其它洗牌的PRRSV蛋白(例如GP2,GP3,GP4,M和非结构蛋白)的感染性嵌合病毒; 包括PRRSV嵌合洗牌的GP5蛋白和/或其它改组的PRRSV蛋白(例如GP2,GP3,GP4,M和非结构蛋白)的广泛保护性亚单位疫苗。
