现代养猪设施通常饲养密集的猪群，并可能携带各种潜在的人畜共患病病毒，这些病毒可以从一个猪代传播到另一个猪代，并定期感染人类看护者。生物气溶胶采样是一种常用技术，多年来一直用于在养猪生产和其他类似环境中进行微生物风险评估。然而，这些工作的大部分似乎集中在非病毒微生物因子的检测上（即，细菌、真菌、内毒素等），在猪场检测病毒气溶胶的努力似乎很少。这些研究产生的数据对评估病毒传播和生态特别有用。在这里，我们总结了文献综述的结果，以确定已发表的文章与生物气溶胶的产生和检测在猪生产设施，重点是空气传播的病毒。我们确定了1991年至2017年期间发表的73份科学报告，这些报告被纳入本次审查。其中，19个（26.7%）使用抽样方法检测病毒。我们的研究结果表明，在养猪生产环境中的生物气溶胶采样方法主要集中在细菌和真菌的检测，不同的方法之间没有明显的标准化。信息，特别是关于猪生产环境中病毒气溶胶负荷的信息似乎有限。然而，在过去5年中，病毒气溶胶研究的数量显著增加。随着新的采样技术和改进的诊断方法的出现，病毒生物气溶胶采样可能是在猪场中进行非侵入性病毒监测的一种有前途的方法。
Modern swine production facilities typically house dense populations of pigs and may harbor a variety of potentially zoonotic viruses that can pass from one pig generation to another and periodically infect human caretakers. Bioaerosol sampling is a common technique that has been used to conduct microbial risk assessments in swine production, and other similar settings, for a number of years. However, much of this work seems to have been focused on the detection of non-viral microbial agents (i.e., bacteria, fungi, endotoxins, etc.), and efforts to detect viral aerosols in pig farms seem sparse. Data generated by such studies would be particularly useful for assessments of virus transmission and ecology. Here, we summarize the results of a literature review conducted to identify published articles related to bioaerosol generation and detection within swine production facilities, with a focus on airborne viruses. We identified 73 scientific reports, published between 1991 and 2017, which were included in this review. Of these, 19 (26.7%) used sampling methodology for the detection of viruses. Our findings show that bioaerosol sampling methodologies in swine production settings have predominately focused on the detection of bacteria and fungi, with no apparent standardization between different approaches. Information, specifically regarding virus aerosol burden in swine production settings, appears to be limited. However, the number of viral aerosol studies has markedly increased in the past 5 years. With the advent of new sampling technologies and improved diagnostics, viral bioaerosol sampling could be a promising way to conduct non-invasive viral surveillance among swine farms.
