Figure 3.
Phylogenetic analysis based on concatenated alignments of nucleic acid sequences of 4421 core genes from 16 V. nigripulchritudo strains (ATCC 27043T as outgroup). Trees were built by the Maximum-Likelihood method based on sequences aligned using Muscle. Branch lengths are drawn to scale and are proportional to the number of nucleotide changes. Numbers at each node represent the percentage value given by bootstrap analysis of 100 replicates. The pathotype of each strain, when tested, is indicated in parentheses.
