Fig 2. Maximum likelihood tree based on concatenated protein sequences from 23 Leptospira genomes.

The saprophytic non-pathogenic L. biflexa was used to root the tree. Branches highlighted in red are those leading to taxa whose genomes contain the additional cluster of RND transporter components described for serovar Hardjo (see main text). As there was not enough phylogenetic signal to separate individual L. interrogans serovars, those having this cluster are shaded in pink. Bootstrap values are shown for branches separating different species.
