2021年壶关县春季常见羊传染病血清抗体检测

Detection of serum antibodies against FMDV PPRV and brucellosis in sheep herds in huguan county in the spring of 2021

目的了解2021年山西省壶关县春季动物防疫社会化服务5个乡镇(设立2个服务区域A集店、晋庄、龙泉B黄山和百尺)散户常见羊传染病免疫状况,评估疫苗免疫效果。方法随机采集61个行政村72户散养户养殖羊的的630份全血样品,采用间接ELISA方法进行免疫抗体检测。结果羊口蹄疫、羊小反刍和羊布病抗体的总合格率分别为85%、82.22%、95.56%,均达到了农业农村部要求的70%以上标准。不同区域内存在一定差异,其中B区小反刍兽疫抗体合格率达到88.86%,而A区仅77.78%。同时,在羊的3种疫病中布病抗体的合格率最高,均高达90%。结论研究表明,壶关县春季社会化服务散户羊口蹄疫、小反刍兽疫和羊布病免疫状况整体免疫效果较好,值得进一步推广施行,但仍须持续加强免疫和抗体检测,有针对性地“分区域”开展羊疫病防控工作。

In order to make clear the status of immunization against foot-and-mouth disease virus(FMDV)type O,peste des petits and brucellosis in sheep farms in huguan county of shanxi province,and to evaluate the immune effect.A total of 630 serum samples were randomly sampled from 72 free-range households in 61 administrative villages in the spring of 2021,to detect the immune antibodies by indirec ELISA.The results showed that the total qualification rates of antibodies against FMDV type O,PPRV and brucellosis were 85%,82.22%and 95.56%total,both of which reached the national standard(>70%)required by the Ministry of Agriculture and Rural Affairs.There are some differences in different areas,the qualified rate of peste des petits antibody in area B reaches 88.86%,while that in area A is only 77.78%.At the same time,the pass rate of brucellosis is the highest among the three diseases of sheep,all of which are as high as 90%.In short,the overall effect of immunization against FMDV type O,PPRV and brucellosis were good in huguan county,and it is worthy of further promotion and implementation.And it was still necessary to strengthen immunization and antibody detection,and to prevent and control the three diseases“by regions”.
