Multiple sequence alignment of amino acid sequences of the ORF 73 gene from SA OvHV-2 strains and reference sequences derived from OvHV-2 genome sequences (Accession numbers: NC-007646.1, AY839756.1, DQ198083.1) analysed with ExPASy translate tool.

<p>Ref indicates the amino acid sequences of the ORF 73 gene of the OvHV-2 reference genomes obtained from the GenBank. Variable regions are highlighted in rectangles (▯), and groups of amino acid sequences (G) are illustrated on the right side of the align sequences
