| 摘 要： | 参考GenBank中发表的猪瘟病毒（CSFV）序列，设计一对CSFV特异性引物；从CSFV感染猪盐渍小肠中提取总RNA，经逆转录后进行PCR扩增，在盐渍小肠中成功扩增出与预期大小（168bp）一致的特异性条带，而正常猪和感染猪伪狂犬病病毒的猪小肠扩增结果均为阴性．用此方法对40例盐渍猪肠衣样本进行检测，结果与经典抗原检测方法（抗原捕获ELISA法）一致，而兔体交叉反应试验的阳性检出率为RT-PCR的66．7％，表明本RT-PCR技术能应用于盐渍猪肠衣的CSFV检测． |

| Abstract: | A pair of specific primers was synthesized according to the sequences published in GenBank.The specific expected fragment(168 bp) was amplified by RT-PCR from the total RNA extracted from salted casings of pigs infected CSFV,whereas,no amplification were detected in normal or pseudorabies virus(PRV) infected.Forty salted swine casing samples were detected by this method,which showed the same results as antigen capture ELISA test did.Compared with RT-PCR,the positive rate of rabbit-cross reaction test was 66.7%.Thereforet,his method could be applied to the fast and accurate detection of CSFV in salted swine casings. |
