中文摘要:
      为了解湖南省长沙市布鲁氏菌病流行现状,对奶羊养殖场(户)和种羊场采用普查策略,对其他羊养殖场(户)采用两阶抽样策略,选择羊群并选定群体中个体,采集血样进行布鲁氏菌抗体检测。同时,通过问卷调查和查阅资料等方式,分析布鲁氏菌病感染和传播风险。结果显示:全市羊布鲁氏菌病表观场群流行率为1.54%(95%CI:0.42%~3.91%),表观个体流行率为0.60%(95%CI:0.43%~0.80%);4个阳性群集中分布于长沙县和宁乡县;和以往监测数据相比,长沙市的羊群布鲁氏菌病流行率和人间发病率均呈下降趋势,说明前期的防治策略取得积极成效。总体来说,长沙市布鲁氏菌病流行率较低,疫情处于稳定控制状态,因而可以分区域逐步实现全市布鲁氏菌病净化。
英文摘要:
      In order to recognize the epidemic situation of Bruellosis in Changsha City,adopting the general survey strategy for the milk and breeding goat and sheep farms(households),and two-stage sampling strategy for other sheep farms(households),serum samples were collected from the selected individuals of selected goat and sheep herds and the antibodies against Brucellosis were detected. At the same time,the risks of Brucellosis infection and transmission were analyzed according to questionnaires and consulting data. The results showed that the estimated apparent prevalence of Brucellosis in sheep was 1.54%(95%CI:0.42%-3.91%)at herd level and 0.60%(95%CI:0.43%-0.80%)at individual level. Four positive groups were all distributed in Changsha County and Ningxiang County. Compared with the previous monitoring data,the prevalence rate of Brucellosis and the incidence in human decreased,showing that positive results were achieved by the previous control strategy. On the whole,the epidemic situation of Brucellosis is in stable control in Changsha City now,and Brucellosis eradication could be gradually realized by the sub-regional strategy.
