Presence of porcine circovirus type 1 (PCV1) and PCV2 was studied in sera and superficial inguinal lymph nodes from postweaning multisystemic wasting syndrome (PMWS)-affected and non-PMWS-affected pigs by using in situ hybridization and PCR. PCV1 and PCV2 were found in less than 3% and more than 50% of the samples, respectively. The most sensitive technique and site was PCR in superficial ingui...

Introduction African swine fever virus (ASFV), pseudorabies virus (Aujrszky’s disease virus, ADV) and porcine circovirus type 2 (PCV-2) are some of the most dangerous DNA viruses causing high amounts of morbidity and mortality in commercial and backyard pig farms. Traditional diagnosis of porcine viral infections requires complex and lengthy combinations of virological and serological tests. Th...

Porcine dermatitis and nephropathy syndrome (PDNS) is broadly discussed as a porcine circovirus type 2 (PCV2)-associated disease, although PCV2, in contrast to postweaning multisystemic wasting syndrome (PMWS), has to date not been proven to be the aetiologic agent. The clinical signs, gross post-mortem and histopathological changes observed in affected pigs, were similar to those previously de...

Abstract Porcine circovirus type 2 (PCV2), which serves as a major causative agent of PCV2-associated diseases and causes severe loss to the pig industry worldwide, can dysregulate immune response induce immunosuppression in PCV2-infected pigs. Similar PCV2, porcine 3 (PCV3), newly identified swine might be closely associated with dermatitis nephropathy syndrome, reproductive disorder, multisys...
