Type 2 porcine circovirus (PCV2)

PCV2 is a DNA virus classified in the Circovirus genus of the Circoviridae family. This virus is now recognized as the main infectious agent involved in the development of post-weaning multisystemic wasting syndrome (PMWS). The main signs are wasting, shortness of breath, diarrhea, and jaundice, which are often associated with superinfecting bacteria. PMWS strikes weaned piglets between 5 and 18 weeks of age, but reproductive problems—abortion, stillbirth, and premature delivery—have also been observed in sows.
