[发明专利]传染性法氏囊病病毒(IBDV)多聚蛋白基因(VP2/VP4/VP3)、真核表达质粒、DNA疫苗

摘要

本发明提供了传染性法氏囊病病毒(IBDV)多聚蛋白(VP2/VP4/VP3)基因，它比病毒主要宿主保护性抗原VP2基因更能增强疫苗的免疫原性。本发明还提供了以pCI作为真核表达载体，含有上述编码序列的重组载体，它比其它常规真核表达载体的表达能力强10－40倍，基因表达量高可以增强DNA疫苗的效果。。本发明还提供了一种传染性法氏囊病病毒的DNA疫苗，包括上述真核表达质粒和免疫佐剂，其质量比为1∶1－5，它是一种安全、稳定、有效的传染性法氏囊病病毒(IBDV)DNA疫苗，制备简单、贮运方便。
