Emergence of a new type of porcine circovirus (PCV1/2a) in swine in Canada

Between September 2008 and January 2009, three cases (FMV08-1114252, FMV08-1133505 and FMV09-1134568) were submitted to the Veterinary diagnostic service of the University of Montreal.

None of the three submitted cases were related to “Porcine circovirus associated diseases” (PCVAD). Several diagnostic assays were performed including a multiplex real-time quantitative PCR assay (mrtqPCR) for the detection and differentiation of porcine circovirus (PCV) type 2a and 2b genotypes in the lung and lymph nodes(1). Odds results were obtained with the mrtqPCR assay, suggesting genomic mutations in the viral genome.
