摘　　要：Objectives: The balance of the vaginal ecosystem depends on lactobacilli whose biofilm protectsagainst microorganisms that are not normally present or are subdominant in vaginal flora. Vaginal?infection treatments should eliminate pathogens while preserving the?Lactobacillus?flora to prevent relapse or recurrence. The objective of this study was to determine the sensitivity of lactobacilli to antiseptics, antibiotics and antifungal agents used, alone or in combination, in the topical treatment of infectious vaginitis. Materials and Methods: The minimum inhibitory concentration (MIC) of 15 active ingredients and the minimum inhibitory dilution (MID) of 17 pharmaceuticals products were determined for three main?Lactobacillus?strains (L. crispatus,?L. gasseri?and?L. jensenii). Results: The MICs of the antibiotics and antifungal agents were above their critical concentrations in the three strains, contrary to the antiseptics. According to their MID, some pharmaceutical products, especially combinations, inhibit the growth of one or more strains at concentrations that can be found in the vaginal mucosa after application at the usual dosage. Conclusions: Certain topical anti-infective drugs may interfere with the growth of lactobacilli, worsening the vaginal flora imbalance. Maintaining vaginal flora balance should be a selection criterion when choosing an anti-infective therapy.Objectives: The balance of the vaginal ecosystem depends on lactobacilli whose biofilm protectsagainst microorganisms that are not normally present or are subdominant in vaginal flora.
