Fig. 3From: Geographic distribution and molecular analysis of porcine reproductive and respiratory syndrome viruses circulating in swine farms in the Republic of Korea between 2013 and 2016Multiple alignment of ORF5 amino acid sequences of representative isolates in each subgroup (Type 1 PRRSV) (a) and lineage (Type 2 PRRSV) (b). The representative isolates were selected based on main amino acid sequence of neutralizing epitope of Type 1 PRRSV (residues 29–35) [23] and Type 2 PRRSV (residues 37–45) [37]. The solid line box and gray color box represent neutralizing epitope and decoy epiotpe (residues 27–31) [57], respectively. The dot-line box indicates hypervariable regions [58]Back to article page
