Phylogenetic analysis of L. brevis species. a 16S ribosomal tree obtained from the alignment of the 16S rRNA-encoding genes of 19 L. brevis strains, bootstrapped × 1000 replicates, values > 250 are indicated. The 16S rRNA sequence of Enterococcus faecalis V583 (noted EF on the figure) was used as an outgroup. b Phylogenetic supertree obtained from the alignment of 631 orthologous genes among the 19 L. brevis strains used in this study as well as in Enterococcus faecalis V583 (noted EF on the figure) which was used as an outgroup, bootstrapped × 1000 replicates, values > 250 are indicated. Source of isolation for the different L. brevis strains are also indicated
