Abstract:
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. There was PCV3 DNA detected in 4 of 44 dogs [all were negative for PCV2 and canine circovirus (CanineCV)]. Based on sequence analysis, positive sequences were grouped into PCV3 genotypes. However, these isolates had close evolutionary relationships with FoxCV (KP941114) and CanineCV (JQ821392). Further investigations of the epidemiology, evolutionary biology, and pathobiology of PCV3 to dogs are warranted.
