From: NSP2 gene variation of the North American genotype of the Thai PRRSV in central Thailand
Multiple alignment of partial nsp2 amino acid sequences. The amino acid sequence alignment was performed using the nsp2 aa 299 - 587 region of ten Thai NA-PRRSV, SY0608 (Chinese SHF-related isolate) and VR2332. The VR2332 sequence was used as a reference. Identical amino acids and gapped positions (compared with the reference sequence) are shown as dots and hyphens, respectively.
