Journal ArticleDOI
Porcine circoviruses: a review.
Gordon Allan,John A. Ellis +1 more
TL;DR: The diagnosis of PCV2-associated disease is based on the direct demonstration ofPCV2 antigens or nucleic acid in affected tissues, as is the role of the immune response in controlling or augmenting disease.
Journal Article
Isolation of circovirus from lesions of pigs with postweaning multisystemic wasting syndrome.
John A. Ellis,Lori Hassard,Elizabeth Clark,John C. S. Harding,Gordon Allan,P Willson,J Strokappe,Karen Martin,F. McNeilly,Brian M. Meehan,Daniel Todd,Deborah M. Haines +11 more
TL;DR: Results demonstrate a high degree of association between the presence of the circovirus-like virus and postweaning multisystemic wasting syndrome in affected swine.
Journal ArticleDOI
Activation of the Immune System is the Pivotal Event in the Production of Wasting Disease in Pigs Infected with Porcine Circovirus-2 (PCV-2)
TL;DR: In PMWS-affected piglets, extensive replication of PCV-2 was documented by both immunocytochemistry and quantitative viral titrations, suggesting immune activation is a key component of the pathogenesis of PCv-2-associated PMWS in swine.
Journal ArticleDOI
Reproduction of lesions of postweaning multisystemic wasting syndrome by infection of conventional pigs with porcine circovirus type 2 alone or in combination with porcine parvovirus.
S. Kennedy,D Moffett,Francis McNeilly,Brian M. Meehan,John A. Ellis,S. Krakowka,Gordon Allan +6 more
TL;DR: Results indicate that lesions of PMWS can be induced by inoculating pigs with PCV2 alone, thereby fulfilling Koch's postulates.
Journal ArticleDOI
Experimental infection of colostrum deprived piglets with porcine circovirus 2 (PCV2) and porcine reproductive and respiratory syndrome virus (PRRSV) potentiates PCV2 replication.
Gordon Allan,Francis McNeilly,John A. Ellis,S. Krakowka,Brian M. Meehan,I. McNair,I. Walker,S. Kennedy +7 more
TL;DR: Experimental infection of colostrum-deprived pigs with a combined inoculum of porcine circovirus 2 (PCV2) and porcines reproductive and respiratory syndrome virus (PRRSV) potentiated the replication and distribution of PCV2 virus, when compared with pigs inoculated with PCV 2 alone.
