Phylogenetic tree of PEDV partial spike sequences of wild boar strains (gray shadow and diamonds) and GenBank available sequences. Reference strains were indicated as follows; strain (country/year/accession number). Bootstrap replication values using from 1000 replicates are listed as percentages at branch nodes. Bootstrap support values above 70% are shown. Subgroups of the phylogenetic tree were divided as G1, G2, and G3. G1 was further subdivided into G1-1, G1-2, and G1-3 (Park et al., 2007).
