Figure 3

Maximum-likelihood phylogenetic tree based on complete genome sequences of ASFV genotype II from study of the variant in wild boar, Spain, 2025–2026. The analysis included 40 publicly available genomes retrieved from GenBank (accession numbers shown) and the consensus genome sequence SP25WB2611 from our study (bold; wild boar, Spain, 2025 case 1 and 2). We used IQ-TREE (http://www.iqtree.org) to infer the tree with the best-fitting nucleotide substitution model selected by ModelFinder (http://www.iqtree.org/ModelFinder) outside the variable regions. Branch support values are shown at nodes (10,000 ultrafast bootstrap replicates). Scale bar indicates nucleotide substitutions per site. ASFV, African swine fever virus.
