摘要
采用竞争ELISA方法对从重庆市30个区县的种羊场、商品代饲养场和散养户采集的62284份羊血清样品进行小反刍兽疫(PPR)抗体检测。结果显示:53062份血清抗体合格,个体合格率为85.19%,其中种羊场合格率为93.67(3020/3224),商品代饲养场合格率为86.59%(21179/24458),散养户合格率为83.41%(28863/34602),免疫合格率均高于农业部规定的70%的最低标准。监测结果表明,重庆市羊PPR的免疫效果总体比较理想,同时也说明所使用的PPR疫苗免疫原性较好。
By competitive ELISA, 62 284 serum samples from breeding farms, commercial farms and free- range farms of 30 districts and counties in Chongqing city were collected to detect antibodies of PPRV.
