The immune response profile following viral infection was analyzed by hemagglutination inhibition ( HI) test for both acute and convalescent phase sera of the confirmed cases. 血凝抑制(HI)实验检测急性期和恢复期血清,评价检测病毒感染后的免疫应答情况。
Viral isolation was preformed in MDCK cells and hemagglutination inhibition assay was used for subtype identification. 用MDCK细胞进行病毒分离,用血凝抑制试验对分离到的病毒标本进行分型鉴定。
