(See Circovirus)

Porcine circovirus (PCV) is a group of four[1] single-stranded DNA viruses that are non-enveloped with an unsegmented circular genome. They are members of the genus Circovirus that can infect pigs.[2] The viral capsid is icosahedral and approximately 17 nm in diameter.

PCVs are the smallest viruses replicating autonomously in eukaryotic cells.[3] They replicate in the nucleus of infected cells, using the host polymerase for genome amplification.

PCV-2 causes Porcine circovirus associated disease or postweaning multisystemic wasting syndrome (PMWS). An effective vaccination is now available. Fort Dodge Animal Health (Wyeth) launched the first USDA approved vaccine in 2006, containing an inactivated virus (ATCvet code: QI09AA07 (WHO)).[2]
