The authors review the recently described porcine circoviruses and the postweaning multisystemic wasting syndrome (PMWS) of pigs that has been associated with these agents. The widespread type I porcine circoviruses have already been known for at least 25 years and seem to be apathogenic. PMWS, which is characterised by progressive weight loss, respiratory signs, occasionally with jaundice, and consistently combined with interstitial pneumonia and lymphadenopathy, is caused by type II porcine circoviruses. Demonstration of the presence of the causative agent is most commonly performed by immunohistochemistry and PCR, while ELISA and virus neutralisation tests are used for serological investigations. The authors developed a PCR assay for the detection of porcine circoviruses. The accomplished surveys have not found any positive animals in the sampled pig herds.
