The OD600 values of (A) Gardnerella vaginalis, (B) Candida albicans, (C) Lactobacillus iners, (D) Lactobacillus gasseri, and (E) Lactobacillus crispatus after treatment with PAA at concentrations of 1.0, 3.8, and 15.1 mM, converted to a percentage of the control. Data were collected from three independent cultures at each concentration (**P < 0.01, ***P < 0.001).
