Iowa State University Sheds Light on Prevalence of Porcine Circovirus Associated Disease

Research conducted by Iowa State University is shedding new light on the prevalence of Porcine Circovirus Associated Disease within the U.S. swine herd.
Researchers with Iowa State University have completed a study on behalf of the Swine Health Information Center which looked at veterinary diagnostic laboratory data related to Porcine Circovirus Associated Disease.

SHIC Associate Director Dr. Lisa Becton explains circoviruses, including porcine circovirus 2 and porcine circovirus 3, have been associated with clinical syndromes in swine, causing organ failures, skin failures, reproductive issues, gut issues and respiratory issues leading to death loss, increased culling and poor productivity resulting in significant economic loss.

There are four different types of porcine circovirus, one, two, three and four, with porcine circovirus typically not having a pathogenic clinical presentation.
The diagnosis and interpretation of diagnosis for porcine circovirus is relatively complex and so trying to understand the diagnostic results, clinical signs seen on farm and understanding the relevance of what is found has always been a bit of a challenge.
