【摘要】 综述了导致近年来传染性法氏囊病(IBD)疫苗免疫发生重大变化的主要原因,即:传染性法氏囊病病毒(IBDV)超强毒株的出现和IBDV分子生物学研究和分子克隆技术与手段的长足进步。介绍了目前IBD基因工程疫苗的4种主要类型:活病毒疫苗、DNA疫苗、亚单位疫苗、可食用转基因植物疫苗。更多还原

【Abstract】 The main reasons that result in the radical change of infectious bursal disease (IBD) vaccine these years were reviewed. They were the appearing of very virulent of infectious bursal disease virus (vvIBDV),the great advancement in the molecular biology research of infectious bursal disease virus (IBDV) and in the molecular cloning technology and method. Four kinds of genic engineering vaccine of IBDV were introduced: live virus vaccines,DNA vaccines,subunit vaccines,edible transgenic plant vaccines.更多还原
