Cytokine mRNA Expression Profiles in Peripheral Blood Mononuclear Cells from Piglets Experimentally Co-infected with Porcine Reproductive and Respiratory Syndrome Virus and Porcine Circovirus Type 2
Kai-Chuang Shi, Xin Guo, Xin-Na Ge, Qi Liu, Han-Chun Yang
Porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) significantly impact the swine industry worldwide. Co-infections with these viruses are common and several lines of evidence suggest that both PRRSV and PCV2...

Insights into the Evolutionary History of an Emerging Livestock Pathogen: Porcine Circovirus 2
Cadhla Firth, Michael A. Charleston, Siobain Duffy, Beth Shapiro, and Edward C. Holmes
Porcine circovirus 2 (PCV2) is the primary etiological agent of postweaning multisystemic wasting syndrome (PMWS), one of the most economically important emerging swine diseases worldwide. Virulent PCV2 was first identified following nearly simultaneous...
