The ORF3 protein of porcine circovirus type 2 is involved in viral pathogenesis in vivo.

Abstract excerpt

Porcine circovirus type 2 (PCV2) is the primary causative agent of an emerging swine disease, postweaning multisystemic wasting syndrome. We previously showed that a novel identified protein, ORF3, was not essential for PCV2 replication in cultured PK15 cells and played a major role in virus-induced apoptosis. To evaluate the role of the ORF3 protein in viral pathogenesis in vivo, we inoculated 8-week-old BALB/c...
