New research led by researchers at the University of Minnesota College of Veterinary Medicine (CVM) reveals that farmworkers vaccinating and weaning 3-week-old piglets can indirectly and significantly contribute to the spread of the influenza A virus (IAV) on swine farms. This information can help pig producers target biosecurity measures more strategically, curbing swine flu transmission and enhancing swine production outcomes.Continue reading “Recent study pinpoints opportunities to better control swine flu”
Today, we are happy to share a new publication! Dr. Nirmala and colleagues from the University of Minnesota report on a viral RNA extraction method that can be used to detect both the porcine reproductive and respiratory syndrome virus (PRRSV) and influenza A virus (IAV) from used farm air filters. This work is published in the Journal of Aerosol Science. Take a look at it!
- Extracting RNA using TRIzol reagent from filter material ground with liquid nitrogen can be used to detect PRRSV and IAV from air filters.
- IAV was detected in more filters than PRRSV, though PRRSV could be detected in used filters from farms with PRRSV negative status at the time of filter removal.
- The obtained results shows likely evidence of between farm aerosol spread and the methods derived from this study open up avenues to further investigate regional airborne transmission and risk of virus introduction into farms.
