Characterization of emerging porcine parvovirus types in the U.S. pig population
July 21, 2014By Tanja Opriessnig
A new porcine parvovirus (PPV), provisionally designated asPPV5, was identified in U.S. pigs. PPV5 is most closely related to PPV4 with overall genomic...

Identification of Genetic Mutations that Confer Escape from Innate or Adaptive Host Immune Responses During PRRSV Infection In Vivo
July 15, 2014By Susan Carpenter
The major goal of the proposed study was to identify specific genetic mutations in the PRRS virus genome that confer escape from host immune responses during PRRSV infection in vivo. The study used...

Evaluation of time and temperature sufficient to inactivate porcine epidemic diarrhea virus in swine feces on metal surfaces
July 8, 2014By Derald Holtkamp
In May of 2013 porcine epidemic diarrhea virus (PEDV) was detected in swine for the first time in the United States and spread quickly across much of the country, partly due to the movement of...

Determination of the virulence of a mutant PCV2 (PCV2d) recently identified in cases of apparent vaccine failure and the ability of commercial PCV2a vaccines to protect against PCV2d
July 4, 2014By Tanja Opriessnig
PCV2d (formerly known as mutant or mPCV2) emerged in the U.S. in 2012 and important questions on virulence of this novel strain and vaccine protection by currently used vaccines needed to be...
