西藏洛隆县牛羊疫病抗体检测分析

Analysis of Antibody Detection of Cattle and Sheep Epidemic Disease in Luolong County of Tibet

摘要: 为完成西藏洛隆县动物强制免疫疫苗的免疫效果监察工作，本次研究对动物口蹄疫和小反刍两种疫病的免疫抗体检测在2022~2023年完成，具体采集血清样本涉及到洛隆县的孜托镇等五个乡镇，共采集了多份用于口蹄疫兽疫和小反刍兽疫抗体的检测，其中用到的试验方法有酶联免疫吸附(ELISA)试验。结果显示：牛的口蹄疫检测中，牛O型和Asi-I型口蹄疫相比，牛A型口蹄疫的免疫率较高。而羊的口蹄疫检测中，羊O型口蹄疫的抗体免疫整体水平达到92%，符合国家要求。羊的小反刍兽疫抗体检测中，整体合格率为44.6%，结果较差。

Abstract: In order to complete the supervision of the immune effect of animal compulsory immunization vaccine in Luolong County, Tibet, the immune antibody detection of animal foot-and-mouth disease and peste des petits ruminants in this study was completed in 2022~2023. The specific serum samples were collected from five townships such as Zituo Town in Luolong County. A total of several samples were collected for the detection of foot-and-mouth disease and peste des petits ruminants antibodies, and the test method used was enzyme-linked immunosorbent assay (ELISA) test. The results showed that in the detection of foot and mouth disease in cattle, the immune rate of cattle type A foot and mouth disease was higher than that of cattle type O and Asi-I foot and mouth disease. In the detection of foot-and-mouth disease in sheep, the overall level of antibody immunization of sheep type O foot-and-mouth disease reached 92%, which met the national requirements. In the detection of peste des petits ruminants antibody in sheep, the overall qualified rate was 44.6%, and the result was poor.
