  • Prevention of myocarditis, abortion and intrauterine infection associated with porcine circovirus-2
    Patent number: 7211379
    Abstract: Provided is a method for reducing viral load of porcine circovirus type 2 (PCV-2) in a pig by inducing an immune response against PCV-2 through the administration of an immunogenic composition comprising a PCV-2 antigen. A preferred antigen is a vector containing a PCV-2 nucleotide sequence. In a particularly preferred embodiment, the PCV-2 nucleotide sequence is ORF4, ORF13, or ORF4 and ORF13. In some embodiments, the immunogenic composition includes one or more additional pig pathogens.

  • Reduction of porcine circovirus-2 viral load with inactivated PCV-2
    Patent number: 6517843
    Abstract: Porcine circovirus-2 (PCV-2) is a recently identified agent wherein the potential spectrum of PCV-2-associated disease has been expanded by evidence of vertical and sexual transmission and associated reproductive failure in swine populations. PCV-2 was isolated from a litter of aborted piglets from a farm experiencing late term abortions and stillbirths. Severe, diffuse myocarditis was present in one piglet associated with extensive immunohistochemical staining for PCV-2 antigen. Variable amounts of PCV-2 antigen were also present in liver, lung and kidney of multiple fetuses.
