    摘要:

    为估计陕西省绥德县规模场羊布鲁氏菌病流行率及分布情况,寻找群间传播风险因素,随机抽取绥德县存栏>60只的规模羊场102个,采集血清样品3 964份,采用虎红平板凝集试验(RPBT)和试管凝集试验(SAT)进行垂直检测,同时对采样场进行问卷调查。结果显示,绥德县羊布鲁氏菌病群间流行率为32.6%(95%CI:23.5%~41.6%),以田庄、张家砭为主的西南部乡镇和以薛家河、中角为主的中、北部乡镇群流行率最高;对流产物处理不当、1年内有羊只引进以及生产区与生活区没有有效隔离是该病发生的主要风险因素。该研究掌握了绥德县布鲁氏菌病的流行及分布情况,可为绥德县布鲁氏菌病防控提供依据。

    Abstract:

    In order to estimate the status of prevalence and distribution of brucellosis in large-scale sheep farms in Suide County of Shaanxi Province,and to identify the risk factors of disease spreading among populations,3 964 serum samples were randomly collected from 102 farms with more than 60 stocks in the county for vertical detection by rose bengal plate test(RPBT)and standard-tube agglutination test(SAT),meantime,a questionnaire survey was carried out in the sampled farms. The results showed that the prevalence rate at flock level was 32.6%(95%CI:23.5%–41.6%),which remained highest in southwest towns,mainly including Tianzhuang,Zhangjiabian,and in middle and north towns mainly consisting of Xuejiahe and Zhongjiao. The main risk factors for the outbreak including improper treatment for abortion,introduction of sheep within one year,lack of effective isolation among production zones and living zones. In conclusion,the prevalence and distribution status of brucellosis in Suide County was identified,which could provide some references for prevention and control of the disease.
