Figure 3: Evolutionary tree of Brucellaceae sequence. Data was obtained from this study and similar sequences from other investigations, deposited in GenBank; Escherichia coli included as outgroup. The scale bar indicates an evolutionary distance of 0.02 nucleotides per position in the sequence. The sequence derived from the present study is marked with an asterisk. The percentage of trees in which the associated taxa clustered together is shown next to the branches.
