Dear Editor,rnPorcine circovirus type 3 (PCV3) is a new-emerging circovirus belonging to the genus Circovirus in the family Circoviridae in which PCV type 1 (PCV 1) and PCV type 2 (PCV2) were well documented (Palinski et al.2017).PCV1 is a cell culture-derived virus and is considered to be nonpathogenic for swine,whereas PCV2 is the primary etiological agent of porcine circovirus-associated diseases (PCVAD) that causes severe economic losses in the swine industry worldwide (Zhai et al.2014).PCV3 was firstly reported in the United States of America in 2016 (Palinski et al.2017).
