Representation of amino acid substitutions found from the alignment of the partial sequences of the region encoding the PCV3 capsid protein. The classification of types of PCV3 in circulation in the states of Espírito Santo and Rio de Janeiro, Brazil, was carried out according to Fux et al. [20]. Other amino acid changes described in this study are also shown
