Molecular phylogenetic analysis by the maximum-likelihood method based on 16S rRNA gene sequences showing the phylogenetic positions of M. lornae, M. hutchinsoni and M. vaginalis with closely related members of the family Veillonellaceae. The genital tract isolates clustered within the Megasphaera clade. Bootstrap values (based on 1000 replications) greater than or equal to 70 % are shown as percentages at each node. Bar, 0.02 substitutions per nucleotide position. Selenomonas sputigena ATCC 35185 (NR_025115) from the family Selenomonadaceae was added as an outgroup.
