Figure 4.
Phylogenetic tree of different ASFV genotypes built by maximum-likelihood method using sequences corresponding to the central conserved region (CCR, comprising 129 kb between A224L and I196L genes). Arm/07/CBM/c2 (highlighted in red) is grouped within the genotype II strains while Arm/07/CBM/c4 (highlighted in blue) is grouped within the genotype I strains. The tree was built based on MAFFT aligned genomes using IqTree software. Automatic settings were used, resulting in the selection of HKY+FK3PU+F+R2 as the best fit model; statistical support of the shown branches was obtained with an ultrafast bootstrap repetition value of 10,000. Substitution per base rate is indicated in the scale below.
