Identification of Type I Interferon Antagonists of PRRSV Viral Structural Proteins
August 3, 2009By Kay S. Faaberg
PRRSV is an important swine pathogen and infections caused by this virus have not been efficiently controlled. This is in part due to the lack of knowledge about the insufficient swine immune...
