摘要: |
用纯化的猪伪狂犬病病毒gB重组蛋白为抗原,建立了检测猪伪狂犬病血清抗体的gB-ELISA方法。最佳反应条件为:抗原包被浓度为3.15μg/ml,待检血清稀释度为1:40。该方法对猪圆环病毒病、猪瘟、猪细小病毒病、猪繁殖与呼吸综合征(猪蓝耳病)、猪乙型脑炎、猪布氏杆菌病5种疾病阳性血清和SPF猪阴性血清检测呈阴性反应。批间、批内试验变异系数均不超过8%。用该方法与HerdChek ELISA试剂盒同时对119份血清进行了平行检测,其相对敏感性、特异性和符合率分别为:75%、80.7%和79%。试验结果表明:猪伪狂犬病血清抗体gB-ELISA检测方法具有较高的敏感性和特异性,且重复性好,可用于猪伪狂犬病毒血清抗体检测。 |

Abstract: |
The gB-ELISA was established by using the purified PRV gB recombinant protein as antigen for detecting PRV antibodies in pig sera. All reaction conditions of this gB-ELISA were explored. The optimal coating concentration of antigen is 3.15μg/ml,the serum sample was diluted to 1:40. The results are negative when the antiserum against PCV, PPV, HCV, JEV and PRRS were detected by this gB-ELISA.The CV % between and within batches of detection were less than 8%.119 pig sera samples were simultaneously detected by this indirect gB-ELISA and HerdChek gB ELISA kit.The relative sensitivity and specificity of indirect gB-ELISA established in the study were75% and 80.7%. The coincidence rate between these two ELISA was79%.All results showed that this assay had a good sensitivity,specificity and repeatability,it could be used for detection of PRV antibody in pig sera. |
