Senecavirus A (Seneca Valley Virus) in Swine

Aug 07, 2015

Recently, there have been 4 cases of vesicular disease observed in unrelated diagnostic case submissions (3 cases from exhibition swine in Iowa, 1 case from a commercial finishing operation in South Dakota) at the ISU-VDL since July 28, 2015. Foreign animal disease investigations were initiated and samples all tested negative to FMDV, but positive to Senecavirus A. Other vesicular diseases have been ruled out as well. AASV originally reported on the presence of Seneca Valley Virus in October 2012. That article describing the clinical presentation associated with earlier introductions can be accessed on the AASV website. In addition, Drs. Chris Rademacher, Darin Madson, Rodger Main, KJ Yoon, Daniel Linhares, and AJ Smit at Iowa State University Veterinary Diagnostic Lab have compiled a fact sheet entitled Senecavirus A (Seneca Valley Virus) in Swine describing the virus and clinical presentation of the recent cases.

Video: Season 6, Episode 10: Defining Resiliency and the Research Driving Swine Health Forward

Genetic research and new technologies continue to influence the future of swine health and production efficiency. In this episode, we explore how research and technology are being used to support stronger, more resilient pigs, while also improving overall production outcomes. In this episode, we are joined by Dr. Jenelle Dunkelberger, geneticist with Topigs Norsvin, to discuss both routine and emerging strategies for improving piglet, pig, and sow livability. She outlines two primary approaches to enhancing resiliency: gene editing and traditional selective breeding. Continuing the resiliency conversation, we also hear from Dr. Lucina Galina, director of technical research projects at the Pig Improvement Company. She shares insights into ongoing gene-editing work focused on PRRS, detailing the pathway to success, regulatory and practical considerations, and the questions that still remain as the technology evolves. Together, these conversations provide a closer look at how research, genetics and innovation are shaping the future of swine health and livability.
