摘　　要：为评估不同非洲猪瘟病毒(ASFV)检测试剂的检测性能,采用标准阳性血清、标准阴性血清和临床血清,比较了酶联免疫吸附试验(ELISA)、化学发光免疫分析(CLIA)、高敏荧光免疫分析3种ASFV血清抗体检测方法试剂盒的敏感性、特异性、符合率及临床应用效果。分析发现:4个ELISA试剂盒、1个CLIA试剂盒和1个高敏荧光免疫分析试剂盒在检测标准血清时,其敏感性、特异性和符合率差异不显著。3种试剂盒的检测临界值均可达到16倍稀释,但在32倍以上稀释时各试剂盒有所差异,ELISA试剂盒的检测灵敏度总体较高。用历年不同非洲猪瘟疫情猪场的临床血清进行检测,发现不同试剂盒检测的阳性率存在差异,ELISA试剂盒的阳性检出率整体优于其他2种方法的试剂盒。综上表明,3种方法的试剂盒在ASFV检测中都有一定的应用价值,其中ELISA试剂盒具有一定的优势,适用于ASFV的大规模筛查与监测。In order to compare the performance of different kinds of kits for detection of African swine fever virus(ASFV),the sensitivity,specificity,compliance rate and clinical application of 3 serological detection kits including enzyme-linked immunosorbent assay(ELISA),chemiluminescent immunoassay(CLIA)and highsensitivity fluorescent immunoassay(HSIA)were compared using standard-positive sera,standard-negative sera and clinical sera.The results showed that the difference in the sensitivity,specificity and coincidence rate of 4 ELISA kits,1 CLIA kit and 1 HSIA kit was not significant.The detection critical value of the 3 kinds of kits could all reach 16 times dilution,but different when the dilution was above 32 times,and ELISA kit was generally more sensitive.When clinical sera collected from different farms with outbreaks of ASF in the past years were detected,it was found that the positive rates of different kits were different,and better in ELISA kit compared to the others.In conclusion,all of kits could be used to detect ASFV,especially ELISA kit that was superior in mass screening and monitoring of ASFV.
