摘要
猪伪狂犬病是由猪伪狂犬病毒(Pseudorabies virus,PRV)引起的一种高度接触性传染病,以导致母猪繁殖障碍及仔猪死亡为特征,可造成重大经济损失。在我国处于多年稳定控制的状态之后,2011年开始各地陆续有报道伪狂犬的发病流行。新的流行毒株不断被发现,对新流行毒株是否出现变异、毒力是否增强、现有疫苗能否提供保护、新毒株疫苗研制、猪场防控策略等方面的研究进展进行了简要综述。
Porcine pseudorabies is a highly contacted infectious disease induced by PRV, which can cause sows＇ Reproductive barriers and piglets＇ high mortality, resulting large economic losses.After maintaining the state of stability control for many years, prevalence of porcine pseudorabies was reported around successively since2011.New pandemic strains were found.Researchs on gene mutated, virulence increasing, the existing vaccine protection, new strain vaccine and prevention and control strategy, were summarized in this review.
