Postweaning multisystemic wasting syndrome (PMWS) is a disease of pigs first recognised in North America in 1991 and subsequently reported worldwide that is caused by Porcine circovirus 2 (PCV2), a member of the family Circoviridae. The most consistent feature of PMWS is a generalized depletion of lymphocytes. Secondary infections with opportunistic organisms are common. There is evidence that the destruction of thymic lymphocytes has a central role in the pathogenesis of PMWS.The objective of this paper was to describe the microscopic and ultrastructural pathology associated with natural cases of PCV2, as well as PMWS, a key point in the diagnosis of PCV2 infection and associated diseases.
