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.
