Nine, one-year projects have been funded in the National Pork Board's PRRS Initiative.

The PRRS (porcine reproductive and respiratory syndrome) projects include:

  • Serum markers of PRRS virus infection, University of Minnesota;

  • Physical characterization of the complete PRRS virus particle, University of Minnesota;

  • Sampling of adult boars during early infection using a new serum collection technique, Swine Vet Center, St. Peter, MN;

  • Development of a killed subunit vaccine, Iowa State University;

  • Design of a new generation of PRRS virus differential marker vaccines, University of Nebraska;

  • Macrophage (tissues that protect the body against infection) cell lines for laboratory propagation of the PRRS virus, University of Nebraska;

  • Implementation of a PRRS virus strain database, University of Minnesota;

  • Development of a porcine adenovirus-based vaccine for PRRS, University of Saskatchewan; and

  • A pilot project for controlling PRRS within a selected region, University of Minnesota.
