摘要
为评估渭南市羊小反刍兽疫的免疫抗体水平及病毒感染状况,对2019-2022年在渭南市采集的2 499份血清学样品和606份病原学样品,分别采用阻断ELISA方法和荧光RT-PCR方法进行免疫抗体检测和病毒核酸检测。结果显示,小反刍兽疫免疫抗体个体合格率为88.24%,区域场群合格率为91.99%,不同区域免疫抗体水平合格率均高于农业农村部的免疫要求(≥70%)。分类统计不同年份和不同场点类型的免疫抗体合格率均达到国家免疫效果评估要求。病原学样品病毒核酸均为阴性。结果表明渭南市小反刍兽疫防控效果较好,但仍需持续做好小反刍兽疫的强制免疫及监测,确保养殖安全。
In order to evaluate the immune antibody levels and virus infection status of peste des petits ruminants in sheep around Weinan,2499 serum samples and 606 diseased samples collected from 2019 to2022 were tested for immune antibody and virus nucleic acid by blocking ELISA and fluorescence RT-PCR,respectively.The results showed that the qualified rate of individual PPR immune antibodies was 88.24%,and the qualified rate of regional farm herds was 91.99%.The qualified rate of immune antibody levels in different regions was higher than the immune requirements of the Ministry of Agriculture and Rural Affairs(≥70%).The qualified rates of immune antibodies in different years and different scale types met the requirements of national immunization effect evaluation.Viral nucleic acids of diseased samples were negative.The results showed that the prevention and control effect of peste des petits ruminants in Weinan was better,but the compulsory immunization and monitoring of peste des petits ruminants still needed to be done continuously to ensure the safety of breeding.
