摘 要：
为建立一种快速检测猪非典型性瘟病毒(APPV)的方法,本实验建立了APPV SYBR Green Ⅱ荧光定量RT-PCR检测方法。该方法特异性试验结果显示,除APPV外,猪繁殖与呼吸综合征病毒、猪瘟病毒、猪流行性腹泻病毒和猪轮状病毒等常见猪病病原检测均为阴性,表明其特异性良好;该方法最低检测限为2.8×10~3拷贝/μL,敏感性较高;重复性试验的组内、组间变异系数均小于1%。利用该方法对临床56份来自四川各地的临床病料样品进行检测,检出5份阳性样品,且与常规PCR检测方法的阳性符合率为100%。本研究建立的APPV荧光定量RT-PCR检测方法为APPV临床检出以及后期并发症的研究奠定了基础。

摘 要：
In order to establish a rapid detection method for porcine atypical pestivirus(APPV),the APPV SYBR Green Ⅱ real-time RT-PCR detection method was established with a pair of specific primers for APPV.The assay was specific for APPV detection.The method showed a linear relationship from 2.8×10~3 copies/μL to 2.8×10~8copies/μL of APPV cDNA.The intra-and inter-group coefficients of variation were both less than 1%.In addition,56 clinical samples from various areas of Sichuan were tested and 5 positive samples were detected.The positive coincidence rate with the conventional PCR detection method was 100%.The results showed that the APPV real-time RT-PCR detection method established in this study had high specificity and sensitivity for the detection of APPV,which laid the foundation for the clinical detection of APPV and the study of late stage of the disease.
