Phylogenetic and phylogenomics relationships. (A) Phylogenetic relationship of Piscirickettsia salmonis strains, according to the housekeeping genes shared by all complete genomes (i.e., dnaK, groEL, recA, gyrA, gyrB, rpoB, and ftsZ). (B) Phylogenomics tree generated based on a total of 1,732 protein sequences forming part of the P. salmonis core-genome. Trees were obtained through the TreeFinder software, using the maximum likelihood method and a bootstrap with 5,000 iterations. Color shading indicates to genogroup to which each stain belongs (blue: LF genogroup; red: EM genogroup). More information on strain characteristics is provided in Table 1.
