Summary This study applied molecular‐based method to investigate the presence of porcine deltacoronavirus ( PDC oV) in 59 commercial pig farms in South Korea. The results of RT ‐ PCR screening on a relatively large collection of faeces samples ( n  = 681) from January 2013 to March 2015 did not reveal the presence of PDC oV until the end of 2014. However, on March 2015, PDC oV‐positive samples ( SL 2, SL 5) were detected from SL swine farm in Gyeongbuk province. The phylogenetic trees based on the complete spike‐ and nucleocapsid protein‐coding genes showed that SL 2 and SL 5 closely related to the US PDC oV strains rather than those in China. Thought Korean strains of PDC oV isolated in 2014 ( KNU 14.04) and in 2015 ( SL 2 and SL 5) grouped within US PDC oV cluster, the reconstruction of ancestral amino acid changes suggested that they are different.
