    • The invention relates to a multiplex real-time RT-PCR assay with a heterologous internal control system (i.e., EGFP-RNA) for the simple and fast diagnosis of classical swine fever virus (CSFV). Primers and FAM-labeled TaqMan probes, specific for CSFV were selected by analyzing the consensus sequence of the 5 '-non translated region of various CSFV strains. For determining the analytical sensitivity an in vitro transcript (T7-PC3Alf) of the 5' NTR was constructed and tested. Furthermore, a primer - probe system for the detection of the internal control sequence was established, and a multiplex assay using CSF-System 1 and the IC real-time PCR could be performed as a one-tube assay without loss of sensitivity or specificity.
    • 本发明涉及用于简单和快速诊断典型猪瘟病毒(CSFV)的异源内部对照系统(即EGFP-RNA)的多重实时RT-PCR测定。 通过分析各种CSFV毒株5'非翻译区的共有序列,选择引物和FAM标记的TaqMan探针,对CSFV特异性。 为了确定分析灵敏度,构建并测试了5'NTR的体外转录物(T7-PC3Alf)。 此外,建立了用于检测内部控制序列的引物 - 探针系统,使用CSF-System 1和IC实时PCR的多重测定可以作为单管测定进行,而不损失敏感性或特异性。
