    摘要:

    2015年初,湖北省某县启动羊布鲁氏菌病监测净化工作。为了解该县羊布鲁氏菌病的流行现状和阳性场户的地理分布,对该县1 567户养羊场户分两阶段抽样,采用虎红平板凝集和cELISA垂直试验进行检测,获知该县羊布鲁氏菌病的群体血清流行率。结果显示:该县羊布鲁氏菌病真实群体血清流行率为2.00%,不同乡镇和不同养殖规模养羊场户的群体血清流行率分别在0~11.16%和0.67%~25.58%之间不等;检出布鲁氏菌病阳性场户74户,其分布在全县10个乡镇,主要集中在4个乡镇,以存栏量在50只以下的养羊场户居多;不同乡镇和不同养殖规模养羊场户中的布鲁氏菌病分布情况不同。调查结果提示,应根据本底调查结果,制订净化方案,实行布鲁氏菌病区域化管理,同时加强对不同流行区域间羊群移动的检疫监管。

    Abstract:

    In early 2015,the surveillance and eradication program for goat brucellosis was launched in a county of Hubei province. To determine the herd-level seroprevalence and spatial distribution of goat brucellosis,a cross-sectional study was carried out using two-stage random sampling method towards 1567 goat herds in that county. The combination of rose bengal plate test(RBT)and competitive ELISA(cELISA)were used to test serum samples. Results showed a true herd seroprevalence of goat brucellosis of 2.00% in that county,and the values in various townships ranged from 0 to 11.16%,while a range of 0.67% to 25.58% for those herds with different sizes. Through the study,positive results were obtained in 74 goat herds,which were widely distributed in 10 townships,especially concentrated in 4 townships. In addition,the disease mostly outbreaked in goat herds of which the number was below 50,and its distribution depended on various townships and on different herd sizes. According to these results,an eradication plan should be made to conduct regional management for goat brucellosis,targeted control efforts for goat movement between different seroprevalence areas should also be strengthened.
