How CVM researchers are tackling a devastating swine virus

Dr. Corzo presenting on a stage to a crowd — Cesar Corzo, director of the Morrison Swine Health Monitoring Program, presents PRRSV research at a conference.

For decades, veterinarians and producers have struggled to contain porcine reproductive and respiratory syndrome virus (PRRSV).

The highly pathogenic swine virus mutates rapidly, making control a moving target. Pigs infected with PRRSV suffer from high morbidity and mortality rates. Even those who live endure difficulty breathing, fever, and loss of appetite. Today, the disease affects as many as half of all swine breeding farms in the United States. It’s the most costly issue the swine industry faces.

Biosecurity for all: Creating biosecurity plans for swine exhibitors based on secure pork supply templates

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.

Researchers from the Ohio State University, Marissa Hall, Andreia G. Arruda, Magnus R. Campler, and Jacqueline M. Nolting, share the findings of their study which examined extending the secure pork supply (SPS) framework to swine exhibitors.
