摘要：
Objective Monkey B virus(BV), also known as Cercopithecine herpesvirus 1,is an important zoonotic pathogen.According to the national standard, antibodies are detected using BV as an antigen.However, the preparation of BV antigen is very stricted due to biosafety issues.Therefore, in this study, we used alternative antigens to detect the BV antibody by serological assay and verified their specifity and sensitivity.Methods A total of 135 blood samples from rhesus monkeys were tested by two ELISA method (BV and HVP2) and enzyme immunosorbent assay (EIA)method.The positive and suspicious samples were verified by immuno-fluorescence assay (IFA), Western blot and immunoblotting technique using HSV-1 gC1 purified glycoprotein as an antigen.Results The positive rates of HVP2-ELISA, BV-ELISA and HSV-1-EIA were 32.6%, 37.8% and 34.8%, respectively.Consistant result of the three detection method accounted for 91.1% (123/135), and the positive result were confirmed by IFA And WB.There were 12 suspicious samples,in which 33.3% (4/12) were verified to be positive.Conclusions Compared with BV antigen, the sensitivity and specificity of the alternative antigen HSV-1 are moe close than HVP2.Positive and suspicious samples should be verified by several method to avoid missed detection.%目的 猴B病毒(monkey B virus,BV),也称猴疱疹病毒I型(Cercopithecine herpesvirus 1),是重要的人兽共患病原.根据国家标准,猴B病毒作为抗原检测抗体,但由于生物安全问题,抗原制备受到很大限制,因此使用替代抗原进行抗体血清学检测并进行比对验证.方法 应用2种ELISA方法(抗原分别为BV和HVP2)和1种免疫酶法EIA方法(抗原为HSV-1)对本实验室135份送检恒河猴血液样品进行筛查,对阳性及可疑样品再以免疫荧光法IFA和Western blot方法(抗原为HSV-1)以及以HSV-1 gC1纯化糖蛋白为抗原的免疫印迹方法验证.结果 HVP2-ELISA、BV-ELISA和HSV-1-EIA阳性检出率分别为32.6%、37.8%和34.8%;3种方法检测结果一致的样品占91.1%(123/135),阳性结果可被IFA和WB确证;可疑样品12份,33.3%(4/12)的样品经验证检验为阳性.结论 与BV抗原相比,替代抗原HSV-1的敏感性和特异性较HVP2更为接近;阳性样品及可疑样品的确证检验应使用多种方法,避免漏检.
