Location of single point mutations within the ORF68 gene of Polish EHV-1 sequences. Nucleotides are numbered according to accession number DQ172353.1 (GB80_1_2 Ab4 strain). Typical nucleotide positions for each groups [12] are highlighted. Asterisk: ORF68 sequences described in [18]. Dots represent the same nucleotide sequence. Dashes represent deletions. NA: not assigned
