Temporal Shifts in Microbial Communities in Nonpregnant African-American Women with and without Bacterial Vaginosis

Figure 3

Neighbor joining-based phylogeny of 16S rRNA gene clones related to bacterial genera consistently present in participants with bacterial vaginosis. Closely related clones were condensed into trapezia with numbers in parentheses representing, for each group, the number of clones obtained from participant 6 (left) and participant 7 (right). The phylogeny is based on 503 unambiguously aligned nucleotides. Branch points with >75% conservation are represented by a closed circle. Genbank accession numbers for reference species are shown in brackets. A 16S rRNA gene from Aquifex pyrophilus was used as the outgroup. Scale bar represents 0.1 change per nucleotide.
