Medical Term:

porcine circovirus


a virus affecting swine, first isolated in 1974. Types 1 and 2 cause reproductive failure, including stillbirth. PCV is also associated with postweaning multisystemic wasting syndrome; coinfection with porcine parvovirus increases severity of signs. Other findings include chronic wasting disease, lymphadenopathy, and sometimes dyspnea, icterus, and diarrhea. PCV-2 is associated with porcine respiratory disease complex, dermatitis, and nephropathy syndrome. Healthy carriers of PCV types 1 and 2 have been recognized. PCV-2 is considered less pathogenic.
