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.

Detection of PRRSV-2 in air emissions from grow-finish barns

A recently published study conducted by Mark Schwartz and collaborators evaluated the feasibility of using air sampled from right outside the exhaust fans on finishing barns to detect PRRSV. The full article is available in open access on the journal’s website.

Emerging threats of HPAI in swine: knowledge gaps and the imperative for a One Health approach

Today, we are sharing a recently published review article by the Torremorell lab, available in Frontiers in Veterinary Science. This review article opens with a summary and historical perspective of Highly Pathogenic Avian Influenza (HPAI) H5N1 cases in avian species as well as in dairy cows. It makes the case that considering the high mutation rate of IAV and the potential for spillovers in swine, a One Health approach including human, animal and environmental health needs to be taken. Information regarding experimental infections and field observations of HPAI H5N1 in pigs as well as strategies for diagnostic and surveillance, implications for biosecurity and management practices to control the virus are included. Lastly, authors explain the associated concerns for public health.

Recombinants Are the Key Drivers of Recent PRRSV-2 Evolution

The Schroeder’s lab at the University of Minnesota College of Veterinary Medicine recently published a brief report in the journal Pathogens regarding a likely cause of Porcine Reproductive and Respiratory Virus type 2 evolution.

Swine Practitioner Practices on Oral Fluid Sampling in U.S. Swine Farms: A Nationwide Survey

Today, we are sharing a recent publication from the MSHMP team in the journal Pathogens. This project set out to gather information on how swine veterinarians use oral fluids in the USA through a nationwide survey.
