From: Modification of PCV-2 virulence by substitution of the genogroup motif of the capsid protein
Comparison of the capsid protein sequence of the two parental strains and of the two mutants. Differences in amino acids between the two parental isolates are indicated in bold and underlined. The genogroup motif is highlighted in grey. Asterisk indicated the six amino acid difference between two PCV-2 isolates showing difference in virulence [31] and the dot the two mutations responsible for attenuation by Fenaux et al. [31].
