Brucellosis is a major zoonosis worldwide. Many people for their professions are at higher risk of contracting the disease.
To determine the seroprevalence of brucellosis and its risk factors in a group of high risk professions.
In a cross-sectional study, all personnel or students of veterinary schools, slaughters and butchers working in the city were invited to participate (n = 141). A comparison group (n = 44) randomly selected from patients who were selected at random from people attended our healthcare center for reasons other than the infectious diseases.
4 veterinarians, 15 veterinary assistants, 42 veterinarian students, 52 butchers, 17 slaughters, 8 slaughterhouse workers and 3 chefs made the first group and 14 storekeepers, 5 students of engineering, 11 clerks, 13 freelance workers, and 1 high school student made the comparison group. While the rate of consumption of most of the studied dairy products was almost similar in both groups, comparison group patients consumed more often milk (p<0.001) and cream (p<0.001) than the high risk group. 11 (7.8%; 95% CI: 3.4%-12.2%) cases from high risk group and none of the comparison group were found seropositive for Brucella.
Profession is the main factor in seropositivity. Consumption of dairy products and raw milk is not associated with a higher risk of seropositivity.
布鲁氏菌病是一种全球主要的人畜共患病。许多从事特定职业的人感染该疾病的风险更高。
确定一组高风险职业人群中布鲁氏菌病的血清阳性率及其危险因素。
在一项横断面研究中，邀请了该市所有兽医学院的人员或学生、屠宰场工作人员和屠夫参与（n = 141）。从因非传染病原因到我们医疗中心就诊的患者中随机选取一个对照组（n = 44）。
第一组包括4名兽医、15名兽医助理、42名兽医专业学生、52名屠夫、17名屠宰工人、8名屠宰场工人和3名厨师，对照组包括14名店主、5名工程专业学生、11名职员、13名自由职业者和1名高中生。虽然两组中大多数研究乳制品的消费率几乎相似，但对照组患者比高风险组更常饮用牛奶（p<0.001）和奶油（p<0.001）。高风险组中有11例（7.8%；95%CI：3.4%-12.2%）布鲁氏菌血清学检测呈阳性，而对照组无一例阳性。
职业是血清阳性的主要因素。食用乳制品和生牛奶与血清阳性风险升高无关。
