[目的]估计莱西市奶牛布鲁氏菌病的流行率和地理分布，分析奶牛养殖场间布鲁氏菌病的传播风险因素。[方法]对莱西市1803个养殖户30119头应检奶牛，全部采样，采用虎红平板凝集和试管凝集垂直试验，同时开展奶牛布鲁氏菌病问卷调查。利用GIS、Epi Infor TM 7和SPASS软件，开展横断面研究和case-control研究，分析莱西市奶牛布鲁氏菌病阳性场户的空间分布、布鲁氏菌病流行率和养殖场间的风险因素分析。[结果]莱西市布鲁氏菌病的场户血清流行率是2.55%，个体血清流行率为0.38%；单因素分析发现存栏量、养殖模式、养殖环境、是否有专用产犊场地、挤奶方式、运奶方式、粪污是否分开处理、是否使用机械处理粪便等8个因素与奶牛布鲁氏菌病发生有一定关系（p<0.2）；多因素logistic回归分析表明，存栏量少（10只以下）（OR=4.58，95%CI：1.87-11.23，p=0.001）和散养户集中村饲养（OR=2.21，95%CI：1.05-4.63，p=0.036）与该病发生相关。

Objective] To evaluate the brucellosis prevalence in dairy cows,to describe brucellosis distribution and to identify risk factors of brucellosis transmission between dairy farms in Laixi of Qingdao. [Method] All the un-pregnant cows over the age of 3 months in 1803 dairy farms were sampled. Bengal rose plate test and tube agglutination test were used to examine the serum samples. GIS,Epi Inform TM 7 and SPASS software were used to describe the distribu-tion of brucellosis and identify the risk factors. [Result] The individual prevalence of brucellosis was 0.38% and the herd prevalence was 2.55%. Single factor analysis revealed that there were eight factors associated with brucellosis case (p<0.2) including the herd size,farming pattern,feeding environment,special birth shed,way of milking,way of milk transportation,separation of feces and sewage and mechanical handling of feces. The logistic multi-factor re-gression analysis showed that the herd size less than 10 cows(OR = 2.21 [1.05-4.63]) and free ranging farming(OR= 4.67 [1.86-11.22]) were associated with brucellosis transmission between herds in Laixi.
