米纳斯吉拉斯州山羊群中钩端螺旋体病的流行情况很少被研究。本研究的目的是：（1）调查乌贝尔县（MG）钩端螺旋体病（钩体病）的血清学流行情况;（2）核实钩体病血清型;（3）确定受检猪场感染的危险因素。采用显微镜凝集试验检测了11个农场230头动物的血清样品。流行病学调查提供了有关风险因素的分析数据。钩端螺旋体病患病率为31.3%，患病率在1：100 ~ 1：800之间。最常见的血清型为：Autumnalis（30.30%）、Tarassovi（19.20%）、Pyrogenes（13.13%）和黄疸出血群（11.11%）。动物的年龄和种族是与感染显著相关的危险因素（P < 0.05）。在农场一级，生产强度，使用受薪工人，和其他动物的协会都被发现与钩端螺旋体病的频率。结果表明，管理不当是一个因素，有利于在研究区域发生感染。
The prevalence of Leptospirosis in goat herds of the State of Minas Gerais has seldom been studied. The present research had as its objectives: (1) investigate the seroprevalence of Leptospirosis in the county of UberlA cent ndia, MG, (2) verify the Leptospirosis serovars, and (3) identify the risk factors associated with infection on the farms examined. Serum samples from 230 animals in 11 properties were tested using the microscopic agglutination test. An epidemiological examination furnished data for analysis regarding the risk factors. The prevalence of Leptospirosis was found to be 31.3% with variation from 1:100 to 1:800. The most frequent serovars were: Autumnalis (30.30%), Tarassovi (19.20%), Pyrogenes (13.13%), and Icterohaemorrhagiae (11.11%). The ages and races of the animals were among the risk factors found to be significantly correlated (P < 0.05) with infection. At the farm level, the intensity of production, use of salaried workers, and association of other animals were all found to be related with the frequency of Leptospirosis. The results demonstrated that inadequate management was a factor which favored the occurrence of infection in the region of the study.
