摘要 冠状病毒(Coronaviruses,CoVs)是一类具有囊膜的单链RNA病毒,也是目前已知的基因组最大的RNA病毒,在分类上属于套式病毒目(Nidovirales)冠状病毒科(Coronaviridae)冠状病毒属(Coronavirus)[1]。该病毒可以引起动物呼吸道、消化道和神经系统疾病,主要感染人和脊椎动物,后者主要包括猪、牛、犬、猫、鼠、禽类和一些其他动物(含野生动物)等。冠状病毒科分为4个属,即α、β、γ和δ属[2-3]。其中,α属冠状病毒感染人、长翼蝠、猪、犬、猫等[4];β属冠状病毒感染人、猪、牛、马、鼠、家蝠等,人们熟知的引起严重急性呼吸综合征(Severe acute respiratory syndrome,SARS)的冠状病毒和引起中东呼吸综合征(Middle east respiratory syndrome,MERS)的相关病毒等[5]均属β属冠状病毒;γ属冠状病毒感染禽和白鲸2个种,其中最主要的是引起禽传染性支气管炎(Infectious brochitis,IB)[6];δ属冠状病毒感染猪、夜莺、文鸟等[7]。
