Foot-and-mouth disease (FMD) and vesicular stomatitis (VS) cause such similar clinical signs and lesions that laboratory tests are required to distinguish between infections caused by each virus. Using mouse anti-foot-and-mouth disease virus (FMDV) 3B monoclonal or polyclonal anti-vesicular stomatitis virus-New Jersey (VSV-NJ) antibodies and recombinant FMDV 3ABC or VSV-NJ glycoprotein (G) antigens coated to MagPlex beads, competitive Luminex immunoassays (cLIAs) were developed for FMDV and VSV-NJ, respectively. The cLIAs successfully detected antibodies to FMDV 3ABC and VSV-NJ G in sera from infected animals. The diagnostic sensitivity and specificity were 93% and 98%, respectively for FMDV and 93% and 95.4%, respectively for VSV-NJ. These cLIAs are potential alternatives for competitive enzyme-linked immunosorbent assays (cELISAs) and provide the opportunity for multiplexing to reduce time and the amount of serum required for testing.
口蹄疫(FMD)和水疱性口炎(VS)会引发极为相似的临床症状和病变,因此需要借助实验室检测来区分由每种病毒引起的感染。利用包被于磁珠上的鼠抗口蹄疫病毒(FMDV)3B单克隆或多克隆抗水疱性口炎病毒-新泽西株(VSV-NJ)抗体以及重组FMDV 3ABC或VSV-NJ糖蛋白(G)抗原,分别开发了针对FMDV和VSV-NJ的竞争性Luminex免疫分析(cLIAs)。这些cLIAs成功检测出了感染动物血清中针对FMDV 3ABC和VSV-NJ G的抗体。FMDV诊断的敏感性和特异性分别为93%和98%,VSV-NJ诊断的敏感性和特异性分别为93%和95.4%。这些cLIAs是竞争性酶联免疫吸附测定(cELISAs)的潜在替代方法,为多重检测提供了机会,可减少检测所需的时间和血清量。
