摘　　要：为建立一种快速、特异、灵敏的检测鸡细小病毒(chicken parvovirus,ChPV)的方法,根据ChPV的保守基因NS1设计了3条特异性引物,建立并优化了能快速检测ChPV的半巢式PCR方法,对其进行特异性和敏感性试验,并用所建立的方法对48份临床样品进行了检测。特异性和敏感性试验结果显示,建立的半巢式PCR只对ChPV敏感,扩增产物为186bp的特异性条带;其最低能检测到5.62fg/μL的ChPV DNA;而对鸡新城疫病毒、H9亚型禽流感病毒、马立克氏病病毒、鸡传染性喉气管炎病毒、鸡传染性支气管炎病毒不敏感。临床检测结果显示,同时对48份临床样品进行检测,检出率为16.67%(8/48),提示广西区内鸡群存在ChPV感染。本研究建立的ChPV半巢式PCR方法适用于ChPV的临床检测。In order to set up and optimize a semi-nested PCR for rapid detection of chicken parvovirus（ChPV）,three specific primers were designed according to conserved sequences of NS1 gene of ChPV.The specificity and sensitivity of ChPV semi-nested PCR were tested,and the assay was applied to detect 48 clinical samples.The specificity and sensitivity tests showed that this semi-nested PCR was only sensitive to ChPV for amplifying specific band of 186 bp and it could detect 5.62fg/μL of ChPV DNA,without any sensitivity to other viruses,such as Newcastle disease virus,H9 subtype avian influenza virus,Marek＇s disease virus,infectious laryngotracheitis virus and infectious bronchitis virus.48 chicken samples were detected and the positive rate was 16.67%（8/48）.The results of our study demonstrated that the optimized semi-nested PCR could be a method that was suitable for clinical detection of ChPV.
