Table 3.
Nucleotide alignment statistics between the three isolates where each comparison assumes PNG as the reference sequence. Ts:Tv is the transition:transversion ratio, Ds/Dv is the ratio non-synonymous to synonymous nucleotide substitutions during amino acid translation; substitutions at first, second, third protein-coding sequence.
