Nineteen pigs with clinical signs of porcine circovirus associated diseases (PCVAD) on 5 Alberta pig farms were examined pathologically, including gross pathology, histopathology, and immunohistochemistry.

Despite that PMWS commonly affects pigs aged eight to sixteen weeks; most studies of PMWS have been conducted during the period before transfer to finishing herds. This study focused on PCV2 load and antibody dynamics in finishing herds with different PMWS status.

A real-time PCR assay, based on Primer-Probe Energy Transfer (PriProET), was developed to improve the detection and quantification of porcine circovirus type 2 (PVC2).

In this study, we focused on establishing a challenge model for PCV2 to determine whether SIV influences PCV2 replication and increases the severity of PCV2-associated disease.

The present study reports the detection of PCV2, the pathogenic form of the virus, in mice and rats.

This study confirms the hypothesis that PCV2 plays a role in pneumonia and pleurisy in 10-24 weeks old fattening pigs, not only in herds with a high prevalence of PMWS, but also in herds with no clinical signs of PMWS.

PCV-2 transmission is influenced by contact structure that appears worth being taken into account in an epidemic model.

To investigate the transition in concentration of porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) and antibody for these viruses in serum, serum samples were collected from 29 pigs on weaning day and at 7, 14, 21, 28, 53, 84, and 120 days after weaning.

Results of this study suggest for the first time occurrence of PPV and coinfection with PCV2 in crossbred Indian pigs affected with reproductive problem and neonatal mortality.

It has been demonstrated that PCV2 DNA can be detected in boar semen by PCR; however, the biological relevance of this is unknown.
