    摘要:

    为了解山西省长子县猪瘟和猪O型口蹄疫免疫状况,评估疫苗免疫效果,2017—2019年在全县14个乡镇的规模场和散养户中,随机采集1 343场次的6 592份猪血清样品,采用间接ELISA方法进行免疫抗体检测。结果显示:2017—2019年长子县猪瘟和猪O型口蹄疫抗体合格率分别为84.85%、88.14%,均达到了农业农村部规定的70%以上的要求;色头镇抗体水平最低,分别为75.97%、76.39%,其他乡镇大多在80%以上;规模场的抗体合格率(86.32%、91.99%)高于散养户(84.12%、86.25%),差异均显著(P<0.05)。结果表明,长子县猪瘟和猪O型口蹄疫整体免疫效果较好,但仍需持续加强免疫和抗体检测,有针对性地“分区域、按场点”开展猪瘟和猪口蹄疫防控工作。

    Abstract:

    In order to make clear the status of immunization against classical swine fever virus(CSFV)and foot-and-mouth disease virus(FMDV)type O in swine farms in Zhangzi County of Shanxi Province,and to evaluate the immune effect,a total of 6 592 serum samples were randomly sampled from 1 343 farms(times)in 14 towns from 2017 to 2019,covering scale swine farms and free-range households,to detect the immune antibodies by indirect ELISA. The results showed that the qualification rates of antibodies against CSFV and FMDV type O were 84.85% and 88.14%,respectively,both of which reached the national standard(>70%)required by the Ministry of Agriculture and Rural Affairs;the qualification rates of antibodies were lowest in Setou Town,which were 75.97% and 76.39%,respectively,and the rates were all above 80% in most other towns;the antibody qualification rates of scale farms(86.32% and 91.99%)were higher than those of free-range households(84.12% and 86.25%),which were of significant difference(P<0.05). In short,the overall effect of immunization against CSFV and FMDV type O were good in Changzi County. However,it was still necessary to strengthen immunization and antibody detection,and to prevent and control the two diseases“by regions and premises”.
