猪瘟病毒及其致病机制研究进展

Progress in Classical swine fever virus and It's Nosogenetic Mechanism

猪瘟(CSF)是猪的一种高度接触性传染病,该传染病可分为急性、亚急性、慢性、非典型性和不明显型。急性CSF由强毒株引发,一般导致高发病率和死亡率,而弱毒病毒感染则表现不明显。由于疫苗的广泛应用,有效地控制了猪瘟的大流行,减少了急性死亡。但从20世纪80年代以后,临床症状不典型且病程变长的非典型性猪瘟(或慢性猪瘟)成为该病的主要发生形式,持续感染普遍存在,疫苗的预防效果明显下降,使猪瘟防制遇到了新的困难。以目前人类对猪瘟的认识水平,尚难以从分子水平解释这一新变化的成因,这是因为对猪瘟病毒致病机理及其分子基础的认识深度不够。就此,文章综述了猪瘟及猪瘟病毒研究进展,主要涉及CSFV生物学特性、致病机制及其防控,希望能为猪瘟防控提供新的思路和对策。

Classical swine fever virus（CSFV） is a highly infection disease,which causes great economic losses across the world. Swine vaccine has been playing a crucial role in strategy of controlling CSF. But in recent years, the immunological effect of the vaccine is undesideable. There are many factors that cause the immunological fail. In this paper, reviewed latest development in the molecule of CSFV as well as the nosogenetic mechanism, in order to find away to control CSF.
