Figure 1
Maximum likelihood (ML) phylogenetic tree of the Actinobacillus genus. ML trees (1000 ultrafast bootstraps) representing phylogenetic relationship of Actinobacillus species on A 16S rRNA gene level including allele 1 of each Actinobacillus genome; B putative MLST level with concatenated adk, atpG, deoD, zwf, recA, mdh, and pgi genes; C whole genome SNP level (77 341 SNP positions) as compared to the A. equuli subsp. equuli strain CCUG 2041T (CP007715.1) as reference. Species are highlighted in same colours across different trees, with haemolytic and non-haemolytic A. equuli strains highlighted in red and green text, respectively. Tree scales represent number of nucleotide substitutions per site per year.
