Figure 2

Phylogenetic representation of the alignment of 1,486 groups of orthologous genes from 8 available Brucella genome sequences and that of O. anthropi. The long branch leading to O. anthropi has been shortened. Even though B. suis and B. microti are not found within the same clade, they both exhibit a slower evolution rate than most other Brucella species (as shown by their short branch length) resulting in a high overall similarity at the genome sequence level.
