Monitoring and analysis of avian influenza antibody levels in Jiangkou town,Jianyang district,Nanping city from 2020 to 2023
To understand and master the immune antibody efficacy of highly pathogenic avian influenza in Jiangkou town, Jianyang district, Between 2020 and 2023, two large-scale poultry farms and 10 free range households were randomly selected from Jiangkou town in Jianyang district in May and October each year, a total of 683 serum samples were collected, and the levels of H5 and H7 subtypes of avian influenza antibodies were investigated using hemagglutination inhibition tests. The test results show that the qualified rates of avian influenza (H5+H7 subtype) immune antibodies in Jiangkou town, Jianyang district were 95.4％, 96.3％, 97.5％, and 99.1％ in 2020, 2021, 2022, and 2023, respectively, showing an increasing trend year by year; The qualified rate of antibodies in large-scale farms is higher than that in free range households; The qualification rate of avian influenza immune antibodies is higher than the national standard, indicating that the immunization work is relatively solid and effective;Monitoring the immune antibodies a-gainst avian influenza provides a scientific basis for the immune prevention and control of highly pathogenic avian influenza in Jiangk-ou town, Jianyang district, effectively ensuring the healthy development of poultry breeding industry and public health safety.
