2020-2022年将乐县规模化猪场猪伪狂犬病流行病学调查与分析

Epidemiological survey and analysis of porcine pseudorabies in large-scale pig farms in Jiangle county from 2020 to 2022

为了解和掌握将乐县辖区内规模养猪场猪伪狂犬病野毒感染情况和疫苗免疫效果,于2020-2022年共采集县内8个不同规模猪场血清样本1066份,结合春、秋季动物防疫及疫病日常监测工作,应用ELISA方法对采集的血清样品进行gE和gB抗体检测,研究野毒感染情况和免疫抗体水平,为辖区猪场有效防控猪伪狂犬病、制定合理免疫程序及净化方案提供参考。

In order to understand and grasp the infection situation of pseudorabies wild virus and the immunization effect of the vaccine in pigs from large-scale pig farms in Jiangle county,1066 serum samples collected from 8 pig farms of different scale in Jiangle county from 2020 to 2022,combined with animal epidemic prevention in spring and autumn and routine disease monitoring.ELISA method was used to detect gE and gB antibodies in the collected serum samples to study the infection rate of wild virus and the level of immune antibodies,so as to provide reference and basis for the effective prevention and control of swine pseudorabies in pig farms in the jurisdiction and the formulation of reasonable immune procedures and purification programs.
