Sequence alignment of the deduced amino acid (aa) sequences of the capsid proteins (encoded by ORF2) of the 19 PCV2 isolates. Mutations at the C terminus of the capsid protein in four isolates are shown, resulting in elongation of the ORF by one lysine residue (AH, MDJ and BDH) or by an asparagine and a glutamic acid residue (YJ), compared with the wild-type sequence (green box).
