Figure 1.

Relative abundance of vaginal bacteria at 0, 4 and 8 weeks by sequencing of the 16S rRNA gene. Each cluster of three columns represents a vaginal swab from each of the three time points from a single participant (A) and the study arm is identified below (B). Lactobacillus dominance (defined as > 50% of sequences from Lactobacillus species) was largely consistent across all visits, with few women changing to or from a Lactobacillus dominant state (C). The dotted line distinguishes women whose MBS improved (n=21) on the left and women who did not report an improvement in MBS (n=9) on the right.
