Abstract
Between 2016 and 2018, the prevalence of porcine kobuvirus (PKoV) and porcine astrovirus (PAstV) in Korean wild boars (n = 845) was 28.0% and 10.7%, respectively. Coinfection by both viruses was detected in 5.1% of boars. Phylogenetic analysis revealed that 134 PKoV isolates belonged to diverse lineages within the species Aichivirus C; however, one strain (WKoV16CN-8627) clustered with bovine kobuvirus (Aichivirus B). Forty-seven PAstVs belonged to lineage PAstV4, and only one strain (WAst17JN-10931) was a novel addition to lineage PAstV2. The two viruses were more prevalent in boars weighing ≤ 60 kg than in boars weighing > 61 kg.
Data availability
The partial 3D gene (488 bp) sequences of 135 PKoV strains (accession numbers MW297847-MW297981) and the partial RdRp-ORF2 gene (799 bp) sequences of 48 PAstV strains (accession numbers MW297982-MW298009, MW298011-MW298014, MW298018-MW298019, MW298023, MW298027, MW298034, MW298039-MW298041, MW298044, MW298047, MW298049-MW298053, and MW298056) detected in Korean wild boars have been deposited in the GenBank database.
