Brucellosis and Q fever are considered as occupational hazards to people in contact with domestic animals or their carcasses. The present cross-sectional study was carried out to determine the seroprevalence of brucellosis and Q fever among professions at risk in the North Khorasan Province, northeastern Iran during 2020.
In this study, 185 sera samples were collected from butchers, slaughterhouse workers, farmers, and veterinarians in different counties of the province. The collected sera were tested by ELISA test for the detection of IgG antibodies against and spp. A questionnaire was filled for each participant to investigate demographic characteristics information (i.e., age, gender, educational status, occupation, years of occupational experience, and location), and any exposure to risk factors (animals Keeping, consumption of unpasteurized dairy products, exposure to ill or dead animals, tick bite, splashing animal fluids, travel history, and use of personal protective equipment) that could be associated with these infections.
The seroprevalence of antibodies against and spp. were 17.2% and 19.4%, respectively. Twelve participants also had Q fever and brucellosis co-infection, with a prevalence of 6.4%.
Based on the results, it is concluded that brucellosis and Q fever occur among the high-risk populations in this area and it needs more surveillance to control the diseases by public health and veterinary authorities.
布鲁氏菌病和Q热被认为是接触家畜或其尸体的人员面临的职业危害。本横断面研究旨在确定2020年期间伊朗东北部霍拉桑省北部高危职业人群中布鲁氏菌病和Q热的血清流行率。
在本研究中，从该省不同县的屠夫、屠宰场工人、农民和兽医中收集了185份血清样本。采用酶联免疫吸附测定（ELISA）检测收集的血清中针对布鲁氏菌属和伯氏考克斯体属的IgG抗体。为每位参与者填写一份问卷，以调查人口统计学特征信息（即年龄、性别、教育程度、职业、职业经验年限和地点），以及任何可能与这些感染相关的危险因素暴露情况（饲养动物、食用未巴氏杀菌的乳制品、接触患病或死亡动物、蜱叮咬、溅到动物体液、旅行史和使用个人防护装备）。
针对布鲁氏菌属和伯氏考克斯体属的抗体血清流行率分别为17.2%和19.4%。12名参与者同时感染了Q热和布鲁氏菌病，患病率为6.4%。
根据研究结果得出结论，该地区高危人群中存在布鲁氏菌病和Q热，公共卫生和兽医当局需要加强监测以控制这些疾病。
