Summary Porcine circovirus type 3 ( PCV 3) is a novel circovirus that was associated with porcine dermatitis and nephropathy syndrome, reproductive failure, and multisystemic inflammation. Recently, a PCV 3 strain was identified from pyretic and pneumonic piglets in Guangdong province, China. This virus strain was sequenced and designated PCV 3‐China/ GD 2016. The complete genome of PCV 3‐China/ GD 2016 is 2,000 bp in length and shared 99.1% and 99.1% nucleotide identities with PCV 3/29160 and PCV 3/2164, respectively. [Corrections added after initial online publication on 13 March 2017: The numbers ‘98.5%’ and ‘97.4%’ has been changed to ‘99.1%’ and ‘99.1%’ in the previous sentence.] Phylogenetic analysis based on the complete genome showed that PCV 3‐China/ GD 2016 clustered with the emerging PCV 3 and separated with other virus in genus Circovirus . The results of this study suggest that PCV 3 has existed within the pigs of China. It is urgent to investigate the pathogenicity and epidemiology of this novel circovirus China.
