Key Points
Little is known about the type and nature of viruses that get trapped in commercial filters on swine farms due to a lack of sampling methods.
The first part of this study established effective methods for eluting and identifying PRRS and IAV viruses in MERV filters under lab conditions.
The second part of the study tested the verified method on used filters from swine farms, verifying the presence of both PRRS and IAV.
Porcine reproductive and respiratory syndrome (PRRS) and influenza A virus (IAV) are both transmitted by air and are the two major respiratory viruses that often co-circulate in swine farms. Air filtration systems are used by swine farms as part of their biosecurity measures, implemented to reduce infection risk, often targeting PRRS. Continue reading about how PRRS and influenza A viruses are detected from barn air filters.
