As shown in Table 1, in addition to pigs, IDVs have been isolated from cattle and have so far been classified into three lineages: D/OK (D/swine/Oklahoma/1334/2011-like viruses), D/660 (D/bovine/Oklahoma/660/2013-like viruses) and D/Japanese, with D/Japanese lineage being further classified into 2 sublineages, D/Yama2016 (D/bovine/Yamagata/10710/2016-like viruses) and D/Yama2019 (D/bovine/Yamagata/1/2019-like viruses), based on phylogenetic and antigenic analyses [73].
