Phylogenetic analysis using ORF5 nucleotide sequences of Type 1 (a) and Type 2 PRRS (b) field isolates obtained from this study and the GenBank database. The tree was constructed by maximum-likelihood method and the grouping was referred from the previous studies [30, 31, 56]. Prototype viruses of each type, vaccine viruses used in Korean swine farms and Korean reference strains were marked with ◆, ★ and ▲, respectively. CRESA11 was marked with ●. A group of NADC30-like viruses was magnified in (c)
