摘要
猪瘟病毒(CSFV)是一种严重危害养猪业的正链RNA病毒,猪只感染后可引起猪瘟(CSF)。猪瘟为猪的高度接触性传染病,可分为急性型、亚急性型、慢性型、非典型或温和型猪瘟。近年来,猪瘟的发生在国内外部分地区有流行趋势,该病不但发病率高,同时出现了新的流行特点,如隐性感染、混合感染等,给防控工作带来了较大的难度,也给很多养猪场造成了一定的经济损失。综述了CSFV病原学特性、致病机制、CSF诊断方法及疫苗防控研究现状等内容,以期为今后猪瘟的防控提供新的思路和对策。
Classical swine fever （CSF）,caused by classical swine fever virus （CSFV）,one plus strand RNA virus,is a highly contagious porcine disease,and it can cause a severe harm to pigs.Its course is cute,subacute,chronic,atypical or mild.In recent two years,CSF is epidemic in some domestic and international areas.The disease has high incidence and new epidemic characteristics such as subclinical infection and mixed infection,which makes prevention more difficult and leads to some economic losses in many pig farms.This paper briefly reviews the etiological characteristics and pathogenesis of CSFV,diagnosis and status of vaccine prevention and research of CSF in order to provide new ideas and measures for the future prevention and control of CSF.
