The effects of the recent vaccinations against bluetongue virus serotype 1 (BTV-1) and BTV-8 in Europe on the reliability of enzyme-linked immunosorbent assays (ELISAs) currently used for diagnosis of small-ruminant lentivirus (SRLV) infection were examined. Primary vaccination against BTV-8 in goats induced an increase in reactivity that did not exceed 3 months in a whole-virus indirect ELISA and a competitive ELISA based on the gp135 glycoprotein. Subsequent BTV-1/8 vaccination extended the time scale of false-positive reactivity for up to 6 months. These results are of relevance for SRLV-monitoring programs.
研究了欧洲近期针对蓝舌病毒血清型1(BTV-1)和BTV-8的疫苗接种对目前用于诊断小反刍兽疫慢病毒(SRLV)感染的酶联免疫吸附测定(ELISA)可靠性的影响。山羊初次接种BTV-8疫苗后,在全病毒间接ELISA和基于gp135糖蛋白的竞争ELISA中,反应性增加,且持续时间不超过3个月。随后接种BTV-1/8疫苗,假阳性反应的时间范围延长至6个月。这些结果与SRLV监测计划相关。
