Overview of the results obtained with real-time PCR for L. crispatus , L. jensenii , L. gasseri , L. iners , G. vaginalis and A. vaginae. x-axis: each bar represents a different sample. y-axis: logarithmic scale of cells/ml. Spaces in between horizontal lines represent log10 0.5 differences. Detection limits are 3.5 for L. crispatus, 4.0 for L. jensenii, 4.5 for L. gasseri, 3.5 for L. iners, 4.5 for G. vaginalis and 3.5 for A. vaginae. Data sorted per grade according to decreasing concentration of L. crispatus.
