Figure 1. Lactobacillus spp. and the vaginal pathogenic bacteria quantified by species-specific quantitative PCR (qPCR).

Figure 1

The relative abundance of the vaginal pathogenic bacteria and Lactobacillus were compared to the copy number of total bacteria. The relative abundance of L. crispatus, L. iners and L. jensenii was compared to the copy number of Lactobacillus. The Mann-Whitney U-test was used to evaluate statistical difference between the BV-positive and BV-negative groups. * indicates P<0.05; ** indicates P<0.01.
