摘要
为掌握浙江省羊布鲁氏菌病(以下简称"布病")流行情况,2018-2022年累计在6 810个场点采集375 433份血清学样品,使用虎红平板凝集试验和试管凝集试验对羊血清布病抗体进行检测.结果显示:2018-2022年浙江省羊布病群体阳性率分别为0.16％、0.41％、0.29％、0.13％、0.07％,个体阳性率分别为0.090％、0.080％、0.280％、0.010％、0.004％,种羊场、商品代养殖场、散养户和流通场所个体阳性率分别为0、0.09％、0.01％、0.19％,温州、湖州、衢州、金华、嘉兴等5个地市个体阳性率分别为0.29％、0.16％、0.10％、0.03％和0.02％.结果表明,5年来浙江省羊布病防控成效明显,阳性率呈整体下降趋势,但羊养殖量大、交易频繁地区的防控形势不容乐观,流通场所仍是羊布病防控的薄弱环节.建议坚持检测、扑杀、无疫小区和净化场建设等措施,探索使用先进科技手段有效打击违规调运行为,进一步降低羊群布病流行率,维护畜牧业生产安全和公共卫生安全.
Abstract
In order to investigate the prevalence status of sheep brucellosis in Zhejiang Province,a total of 375 433 serological samples were collected from 6 810 premises from 2018 to 2022 for rose bengal plate agglutination test(RBT)and standard-tube agglutination test(SAT).The results showed that the population positive rates were 0.16％,0.41％,0.29％,0.13％and 0.07％,respectively from 2018 to 2022,and the individual ones were 0.090％,0.080％,0.280％,0.010％and 0.004％,respectively.The individual positive rates were 0,0.09％,0.01％and 0.19％,respectively in sheep breeding farms,commercial farms,free-range households and premises for sheep circulation,and 0.29％,0.16％,0.10％,0.03％and 0.02％,respectively in Wenzhou,Huzhou,Quzhou,Jinhua and Jiaxing cities.In conclusion,the measures for brucellosis prevention and control were effective in the past five years,with decreasing positive rate in general,but the regions with large amount of sheep production or frequent trade were not promising,especially the premises for sheep circulation.It was recommended to further implement such measures as testing,stamping-out,construction of free zones and purification farms,develop advanced technical tools to effectively fight against illegal transportation,so as to further reduce the prevalence of sheep brucellosis,and safeguard the safety of livestock production and public health.
