摘要

摘要: 白斑综合症病毒(white spot syndrome virus,WSSV)是对虾的最主要病毒病原之一,给对虾养殖造成了巨大的经济损失。WSSV分别与三种该病毒膜蛋白VP39,VP124和VP187的特异性抗血清在体外作用后,再注射到螯虾体内,进行中和试验。结果显示,注射同或未同VP124抗血清作用的WSSV,8 d后螯虾的死亡率分别是100%和60%,WSSV的感染能够被抗VP124抗体中和。进一步利用定量PCR分析上述三种特异性抗血清对病毒感染的影响,结果显示,VP124抗血清可抑制WSSV在螯虾体内的增殖。所有结果表明,VP124在病毒的感染中起作用。

Abstract: White spot syndrome virus (WSSV) is one of the major shrimp pathogens causing large economic losses for shrimp farming.In an attempt to identify the envelope proteins involved in the virus infection, purified WSSV virions were mixed with three antisera against WSSV envelope proteins (VP39, VP124 and VP187), individually.And then they were injected intramuscularly into crayfish to conduct in vivo neutralizationassays.The results showed that for groups injected with virions only and groups injected with virions and the VP124 antiserum mixture, the crayfish mortalities were 100% and 60% at 8 day spost-infection, individually.The virus infection could be neutralized by antibody against the envelope protein VP124.Quantitative PCR were used to further investigate the influence of three antisera above described on the virus infection.The results showed that the VP124 antiserum couldrestrainthe propagation of WSSV in cray fish.All of the results suggested that the viral envelope protein VP124 played a role in WSSV infection.
