Genus Brucella phylogenic tree based on a concatenated alignment of orthologous genes. Phylogenetic representation of species in the genus Brucella based on a concatenated alignment of orthologous genes belonging to Ochrobactrum intermedium and 39 different Brucella strains or species whose genomes are nearly complete. At each leave of the tree is summarized the presence or absence pattern of the largest sequence fragments being unshared between B. microti CCM 4915 and B. pinnipedialis B2/94 (black square: presence, gray square: partial presence, white square: absence). Because of the very different scale of divergence of the different species in consideration in this work, the figure has been split in two parts. The upper part is a bird eye view showing the more distant O. intermedium, Brucella sp. B02, B. inopinata, Brucella sp. NF2653 and Brucella sp. 83/13 while the lower part displays the host-adapted Brucella species and B. microti. All nodes have bootstrap values above 99 (on 100 replicates) except when noted in red.
