摘要
根据GenBank中已登录的猪传染性胃肠炎病毒(TGEV)、猪流行性腹泻病毒(PEDV)的序列,利用Primer 5.0设计合成了2对特异性引物。用这2对引物对TGEV、PEDV cDNA模板首先进行单项PCR条件优化,然后采用正交试验设计优化多重RT-PCR反应条件,结果同时扩增到2条与实验设计相符的492bp(PEDV)和211bp(TGEV)特异性条带,建立了能够同时检测2种病毒混合感染的特异、灵敏的多重PCR检测方法,可检测出约11pg的PEDV和13pg的TGEV。
Based on the sequences of porcine transmissible gastroenteritis virus, （TGEV）and porcine epidemic diarrhea virus（PEDV）in GenBank, two pairs of special primers were designed. The PCR reaction of PEDV or TGEV was optimized first. Design L9 （34） orthogonal experiment to find optimal reaction conditions. Under the optimized reaction conditions, products of 492 bp for PRDV and 211 bp for TGEV were simultaneously amplified in the duplex PCR. The results showed that the duplex PCR for the detection of PEDV and TGEV with high sensitivity and specificity was developed with minimal detectable amounts of PEDV and TGEV around 11 pg and 13 pg,respectively.
