Enhancing U.S. swine farm preparedness for infectious foreign animal diseases with rapid access to biosecurity information

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

In today’s Science Page Christian Fleming, Kelsey Mills, Nicolas C. Cardenas, Jason A. Galvis, Cesar Corzo, Denílson dos Santos Ebling, and Gustavo Machado look at the value of the Rapid Access Biosecurity application (RABapp™) as a centralized tool for standardizing and auditing biosecurity plans at a national scale.

Best of Leman 2025: Mike Rahe – Comparison of immune response to circulating PRRSV isolates

You can find all of the presentations selected from previous conferences on the blog here.

This presentation was given by Mike Rahe of North Carolina State University during the 2025 Allen D. Leman Swine Conference.

Size distribution and viral RNA load of influenza virus-laden airborne particles emitted from pigs over the course of an H1N1 infection

This recent article published in Nature Scientific reports by the Torremorell lab describes the size of particles shedding by pigs experimentally infected by H1N1 influenza A virus, as well as their associated viral load.

Assessment of SVA Trailer Contamination at the Harvest Facility

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.
