First molecular detection of porcine circovirus type 3 in dogs in China.

Porcine circovirus type 3 (PCV3) has recently been isolated from diseased pigs within the USA. The objective was to detect the presence of PCV3 in dogs. Nested polymerase chain reactions (PCR) with PCV3-specific primers for the capsid gene were used to detect PCV3 genomic DNA in serum samples from dogs (n = 44) in China.
