Genetic analysis of PCV2 ORF2 isolated from 2016 to 2018 in Korea. ORF2 sequences of 164 PCV2 isolates were analyzed with 47 PCV2 references. a Phylogenetic-tree analysis of Korean isolates by genotypes, PCV2a (), PCV2b (□), and PCV2d (■). The phylogenetic tree was constructed using MEGA6 software with the neighbor-joining method, and bootstrap values were calculated on 1000 replicates. b Genotype isolation rate for PCV2 field viruses according to isolation year. The parentheses indicate the number of isolates. c ORF2 nucleotide (NT) and amino acid (AA) sequence similarity of PCV2 isolates
