The aim of this paper was to study some epidemiological aspects of the infection by Brucella abortus in risk occupational groups in the microregion of Araguaína, Tocantins. For antibody research, 645 serum samples were analyzed by the complement fixation test (CF). A 4.0% frequency was found (26/645) in patients' serum and among those 4.1% (23/551) were slaughterhouses employees and 8.1% (3/37) rural workers. Of the total positive samples, three (2.0%) were women and 23 (4.7%) men; ten (2.9%) were between the ages of 18 and 30, six (3.4%) between 31 and 40, and nine (8.0%) were above 41 years of age. Risk factors for brucellosis in the study groups were age, background (OR = 2.45; CI 95% = 0.98 to 6.10) and previous work conducted with production animals (OR 2.36; CI 95% = 0.95 to 6.02). It was concluded that the infection by Brucella abortus is found in some risk occupational groups in the microregion of Araguaína, Tocantins, and control and prophylactic measures must be implemented emphasizing risk factors identified in the study.
本文旨在研究托坎廷斯州阿拉瓜伊纳微区域中布鲁氏菌感染在高危职业群体中的一些流行病学特征。为进行抗体研究，采用补体结合试验（CF）对645份血清样本进行了分析。在患者血清中发现感染率为4.0%（26/645），其中屠宰场员工的感染率为4.1%（23/551），农民工的感染率为8.1%（3/37）。在所有阳性样本中，女性有3例（2.0%），男性有2例（4.7%）；年龄在18至30岁之间的有10例（2.9%），31至40岁之间的有6例（3.4%），41岁以上的有9例（8.0%）。研究组中布鲁氏菌病的危险因素包括年龄、背景（比值比=2.45；95%置信区间=0.98至6.10）以及之前从事与生产动物相关的工作（比值比2.36；95%置信区间=0.95至6.02）。研究得出结论，在托坎廷斯州阿拉瓜伊纳微区域的一些高危职业群体中发现了布鲁氏菌感染，必须实施控制和预防措施，并重点关注研究中确定的危险因素。
