Phylogenetic tree based on 127 CDSs present in all 38 strains. The 127 CDSs used for this tree are present in all strains, have no paralogs and show no signs of recombination. The tree is rooted at midpoint. Outgoing branches of a node are depicted in black if bootstrap support (100 replicates) at the node is ≥ 70%; in grey otherwise.
