2024年山东省家畜口蹄疫监测数据分析OA

In order to identify the level of immune antibody and prevalence of foot-and-mouth disease(FMD)among livestock in Shandong Province in 2024,and to evaluate the effectiveness of immunization,serum,tonsil and oronasal-pharyngeal(O-P)fluid samples were collected from pigs,cattle,sheep and other livestock in 16 prefecture-level cities of the province to detect antibody and pathogen of the disease,respectively,using blocking ELISA and fluorescent RT-PCR.The results showed that a total of 272 800 samples were tested for FMD immune antibody,with a qualification rate of 95.19％;98 600 samples were for infection antibody,revealing an individual positive rate of 1.08％and a farm/herd positive rate of 2.74％;and 44 400 samples were for pathogen testing,without any nucleic acid positive cases detected.In conclusion,FMD immunization program was effectively implemented in Shandong Province,with high level of immune antibody throughout the year,and low risk of regional outbreak,as no any pathogen had been detected,but there was still possible risk of sporadic outbreak,which should be continuously monitored.
