2014年甘肃省畜间布鲁氏菌病监测及结果分析

为进一步了解甘肃省畜间布鲁氏菌病的流行范围和趋势,为未来布鲁氏菌病防控提供技术资料支撑,本研究采用抽样调查的方法,采集甘肃省不同地区黄牛、奶牛、羊、猪等易感动物血样685814份,进行畜间布鲁氏菌病流行病学调查。结果显示,甘肃省2014年布鲁氏菌病共检牛97245头,检出阳性230头,阳性率0.24%;共检羊587148只,检出阳性7805只,阳性率1.33%;共检猪1421头,均为阴性。监测结果显示:甘肃省畜间布鲁氏菌病感染率呈现出明显的种间与区域的不均衡性,本试验的结果为有效推动全省布鲁氏菌病的防控提供了新的思路。     

布鲁氏杆菌病检测方法的对比试验

布鲁氏杆菌病是由布鲁氏杆菌引起的人与畜均可感染的传染病,家畜中牛、羊、猪最常发生,感染布病的牛、羊、猪会传染给人和其它家畜,其特征侵害生殖系统及胎膜,出现流产不育。控制与消灭本病的关键所在是准确诊断,本文对比了平板凝集试验、试管凝集试验、快速反应试纸条和布鲁氏杆菌ELISA试剂反应盒4种方法检测布鲁氏杆菌病,试验表明,纸片快速诊断是实验室中诊断布鲁氏杆菌病较准确的方法之一,为净化布鲁氏杆菌病提供了有力手段。
