摘要
为评价ELISA抗体检测对蓝耳病疫情预警以及相应防控方案的可行性,对疑似存在蓝耳病疫情风险的某规模化猪场进行抗体检测。结果显示:该场猪蓝耳病抗体离散度大,S/P值≥2.6的比例占检测数的30.4%,表明该场存在蓝耳病感染风险,并通过RT-PCR检测病原得到证实。对该场母猪群及其仔猪采取活苗紧急免疫防控后,该场疫情得到有效缓解,仔猪存活率由原来的48%提高到88%。结论:蓝耳病抗体ELISA检测具有监测预警作用,采用活疫苗免疫防控蓝耳病方案是可行的。
In order to evaluate ELISA antibody detection for the early warning of the porcine reproductive and respiratory syndrome(PRRS) and the feasibility of corresponding prevention and control plan, antibody detection was carried out on a large-scale pig farm suspected to have the risk of PRRS.The results showed that the antibody dispersion of PRRS in this farm was large, and the proportion of S/P value ≥2.6 accounted for 30.4% of the detected number, indicating the risk of PRRS infection in this farm, and the pathogen was confirmed by RT-PCR detection.After the emergency immunization prevention and control of sow and piglets the live vaccine in this farm, the epidemic situation was effectively alleviated, and the survival rate of piglets was increased from 48% to 88%.Conclusion:ELISA antibody detection of PRRS has the function of monitoring and early warning, It is feasible to prevent and control PRRS by using live vaccine.
