Long-Term Surveillance of Avian Coronaviruses from Wild Bird in South Korea.

ABSTRACT: We examined 2,868 fecal samples from migratory wild birds collected from multiple geographical locations in South Korea during the winter seasons between 2014 and 2022. All samples were obtained from four avian species belonging to the genus Anas within the order Anseriformes: Eurasian teal (Anas crecca), Eastern spot-billed duck (Anas zonorhyncha), Mallard (Anas platyrhynchos), and Northern pintail (Anas acuta). The presence of coronaviruses (CoVs) was confirmed through nested PCR targeting a conserved region of the RNA-dependent RNA polymerase (RdRp) gene. A total of 28 samples (0.97%) were tested positive for CoVs, comprising 17 Gamma coronaviruses (γ-CoVs) and 11 Delta coronaviruses (δ-CoVs). Sequence analysis of newly identified strains showed similarity ranging from 79.2% to 99.4% fo
