2019—2020年南京市高淳区山羊小反刍兽疫抗体监测分析

Surveillance and Analysis of Antibodies Against Peste Des Petits Ruminants in Gaochun District,Nanjing City Goats from 2019 to 2020

该研究于对南京市高淳区19个行政村及2个规模羊场随机采样,并通过竞争ELSIA对羊血清样品中的免疫抗体水平进行检测,以评价该地区小反刍兽疫的整体免疫效果。结果显示,2019—2020年间共抽样检测21个场点的449份血清学样品,平均场点合格率为98.22%,场点合格率均高于80%,符合农业农村部要求的70%及以上标准。结果表明,南京市高淳区小反刍兽疫整体免疫效果较好,疫情暴发风险低,基本达到免疫无疫标准,但对部分免疫效果低于平均值羊场的免疫防控和监测工作仍需加强,以确保免疫效果,坚决遏止疫病发生。
