Bovine brucellosis is a zoonotic disease that causes great economic losses. The disease is endemic in Colombia and animal movements from infected herds carry a risk of introduction to other herds. With the objective of analyzing the animal movements and determining their relationship with bovine brucellosis, we performed a descriptive analysis of the space-time movement of livestock in Colombia between 2006 and 2014. Multiple linear regression models (MLR) were employed to determine the relationship between brucellosis status and animal movements at the province level. The prevalence of bovine brucellosis in cattle was the dependent variable, and a total of 14 independent variables related to location, year, census, and animal movements were included. The prevalence of bovine brucellosis was significantly affected by the province (F = 3.42; P < 0.001), the year (F = 9.03; P < 0.001), and bovine (F = 5.45; P = 0.02) and equine movements (F = 3.8; P = 0.053). Fewer cattle and more horses entered provinces with high prevalence than those with low prevalence, indicating the possible relationship between the animal movements and the brucellosis infection in the country.
牛布鲁氏菌病是一种人畜共患病，会造成巨大的经济损失。该病在哥伦比亚呈地方流行，感染牛群的动物流动存在将疾病传播到其他牛群的风险。为了分析动物流动情况并确定其与牛布鲁氏菌病的关系，我们对2006年至2014年期间哥伦比亚牲畜的时空流动进行了描述性分析。采用多元线性回归模型（MLR）来确定省级层面布鲁氏菌病状况与动物流动之间的关系。牛群中牛布鲁氏菌病的患病率为因变量，总共纳入了14个与地点、年份、普查和动物流动相关的自变量。牛布鲁氏菌病的患病率受到省份（F = 3.42；P < 0.001）、年份（F = 9.03；P < 0.001）以及牛（F = 5.45；P = 0.02）和马的流动（F = 3.8；P = 0.053）的显著影响。与患病率低的省份相比，患病率高的省份进入的牛更少，马更多，这表明该国动物流动与布鲁氏菌病感染之间可能存在关联。
