FIG 3 

Core genome phylogeny of V. anguillarum strains. The maximum likelihood tree was obtained from a concatenated nucleotide sequence alignment of the orthologous core genes (1,723 genes for both chromosomes) for the 28 V. anguillarum strains. The virulence properties of the strains and geographical places of isolation were added to improve comparison. Bootstrap values of <80% were removed from the tree. The horizontal bar at the base of the figure represents 0.6 substitution per nucleotide site. The virulence ranking of the strains is based on three fish larva models (31). HV, high virulence; LV, low virulence; MV, medium virulence.
