Over 50 million hogs are raised annually in the United States for consumption, mostly on industrial hog operations (IHOs). Workers at IHOs are exposed to airborne particulates, zoonotic pathogens, and other workplace hazards, but lack of access to IHOs can hinder exposure assessment in epidemiologic studies. Here, we demonstrate the utility of pig-specific Bacteroidales (Pig-2-Bac) as a biomarker of exposure to pigs and pig waste and to help identify sources of Staphylococcus aureus carriage among IHO workers.
在美国,每年有超过5000万头猪被饲养以供食用,其中大部分是在工业化养猪场(IHOs)。IHOs的工人暴露于空气中的颗粒物、人畜共患病原体和其他工作场所危害中,但无法进入IHOs会阻碍流行病学研究中的暴露评估。在此,我们证明了猪特异性拟杆菌(Pig-2-Bac)作为接触猪和猪粪便的生物标志物以及帮助识别IHOs工人中金黄色葡萄球菌携带源的效用。
