2017~2019年黔东南州小反刍兽疫监测分析

Surveillance and Analysis of Small Ruminant Epidemic in Qiandongnan Prefecture from 2017 to 2019

为了准确评估黔东南州2017~2019年小反刍兽疫(PPR)防控效果,本实验室对黔东南州16个县(市)进行小反刍兽疫免疫抗体和病原学监测。结果表明:2017~2019年共采集5358份羊血清抗体总合格率为81.8%,超过农业部最低标准(70%);3740份羊眼鼻拭子病毒核酸全部为阴性,无野毒感染。规模场免疫抗体合格率最高,达88.6%;散养户合格率为80.6%;屠宰场合格率最低,为76.9%。通过对我州羊群PPR疫苗免疫抗体和病原学监测,可以看到我州小反刍兽疫的免疫效果总体情况良好,为本病的防控提供预警预报信息和防控工作指导。

In order to accurately evaluate the immune effect of pest-ruminant disease(PPR)in qiandongnan prefecture from 2017 to 2019,the laboratory carried out immunoantibody and pathogen monitoring of peste ruminants in 16 counties(cities)of qiandongnan.The results showed that the total qualified rate of goat serum antibody collected from scale farms,free range farms and slaughterhouses in 2017-2019 was 81.8%,which exceeded the minimum standard of the Ministry ofagriculture(70%),3740 sheep eye and nose swabs were negative for viral nucleic acid,without wildvirus infection.The scale field immune antibody qualification rate is up to 88.6%;the qualified rate of free-range households is 80.6%;slaughterhouses had the lowest acceptance rate of 76.9%.Through the state of qiandongnan sheep PPR vaccine immune antibodies and pathogen monitoring,the immune effect of small ruminant in qiandongnan was generally good,and provide guidance for the prevention and control of PPR in qiandongnan.
