摘要: 通过对猪传染性胃肠炎病毒(TGEV)S基因和猪流行性腹泻病毒(PEDV)M基因进行序列分析,本试验利用DNAStar软件分别设计2对特异性引物,扩增片段长度分别为299和437 bp,建立一种针对TGEV和PEDV感染的二重PCR鉴别诊断方法.该方法能同时检测到TGEV和PEDV,而对猪瘟病毒(CSFV)、猪圆环病毒2型(PCV2)、猪繁殖与呼吸综合征病毒(PRRSV)、猪伪狂犬病病毒(PRV)等均无扩增,其检测TGEV、PEDV的极限为104 拷贝/μL;用该方法对临床收集的68份疑似病毒性腹泻仔猪粪便和肠道组织样本进行检测,结果表明本试验建立的二重PCR方法具有特异性强、灵敏度高等特点,能用于临床诊断及流行病学调查.

Abstract: Two pairs of primers used to respectively amplify transmissible gastroenteritis virus (TGEV) S gene and porcine epidemic diarrhea virus (PEDV) M gene were designed to develop a method of differential diagnosis of TGEV and PEDV.The established double PCR could detect S gene of TGEV with the length of 299 bp and M gene of PEDV with the length of 437 bp.Negative results using CSFV,PCV2,PRRSV and PRV as control were obtained.The detection limit of this method was 104 copies/μL.68 clinical samples collected from swine farm were submitted to detect TGEV and PEDV,and the result showed that the established double PCR method with the characteristics of high sensitivity and high specificity could be widely used in clinical diagnosis and epidemiological investigation.

Key words: transmissible gastroenteritis virus (TGEV); porcine epidemic diarrhea virus (PEDV); double PCR; diagnosis
