Abstract:【Abstract】 Objective Monkey B virus(BV), also known as Cercopithecine herpes virus, was significant zoonotic pathogen. Alternative antigens were usually used in the detection of B virus from rhesus monkey sera, because of its strict demand for preparation. But the accuracy of these different detection methods using alternative antigens still need to be verified. Method 135 sera samples from rhesus were detected by HVP2-ELISA 、BV-ELISA and HSV-1-IEA, those candidate indeterminate samples and positive samples were then verified by HSV-1-IFA、HSV-1-WB and HSV-1 gC1 immunoblotting.Results The B virus positive rate of rhesus monkeys were 32.6% by HVP2-ELISA, 37.8% by BV-ELISA and 34.8% by HSV-l-IEA respectively. 91.1%(125/135) of the 135 samples tested by the three methods were consistent, and the results of all samples above could be confirmed by WB and IFA. The rest indeterminate 12 samples were further detected by HSV-1-IFA、HSV-1-WB and HSV-1 gC1 immunoblotting, 33.3%(4/12)of samples were confirmed as positive. Conclusion The sensitivity and specificity of HSV-1,as alternative antigen was relatively more closer than HVP2 to BV. In addition, positive samples and suspicious samples need to be confirmed by a variety of methods in case of leak.
