关岭县秋季羊小反刍兽疫疫苗免疫效果监测

Monitoring of Immune Effect of Peste Des Petits Ruminants Vaccine in Guanling Autonomous County

为评估秋防期间关岭县羊小反刍兽疫疫苗免疫效果,采用ELISA检测法对抽取来自12个乡镇免疫羊群的90份血清样进行检测。结果:羊注射疫苗后未出现免疫副反应或免疫死亡现象,免疫抗体阳性率达到87.78%,免疫效果达到农业部规定要求(≥70%)。结果表明:使用的小反刍兽疫疫苗(Clone 9株)能够诱导羊群产生较高水平的免疫抗体。

To evaluate the immunological effect of Peste Des Petits Ruminants（ PPR） vaccine of sheep in Guanling autonomous county in autumn,the detecting method of ELISA was used to evaluate 90 serum samples of immune sheep selected from 12 towns in Guanling. The results showed that there was no immune response or immune death after the injection of the vaccine,the positive rate reached at 87. 78% and the immune effect reached the requirements of the ministry of agriculture（ ≥70%）.
