摘要 根据猪传染性胃肠炎病毒(TGEV)的S基因序列和猪流行性腹泻病毒(PEDV)的N基因序列,设计特异性的引物和探针。通过对引物和探针浓度等反应液用量以及反应条件等因素进行优化试验,建立了能同时鉴别检测TGEV和PEDV的二重荧光RT-PCR方法。用该方法同时检测其他病原如Po RV、PCV和CSFV时不发生交叉反应,特异性好;较普通PCR均高出3个数量级的敏感性,能够检测10 TGEV和10 PEDV拷贝数,敏感性高;组内重复和组间重复试验结果变异系数小,稳定性好;同时检测2个模板的不同浓度组合试验,干扰性小。本试验建立的二重荧光RT-PCR方法可用于TGEV和PEDV的鉴别检测,且具有特异、敏感、稳定、快速等优点,为进一步应用于TGEV和PEDV的临床鉴别诊断和流行病学调查研究奠定了基础。
