Background and Objectives:
The goal of this study was to determine the effect of various treatment regimens on vaginal colonization by H2O2-positive and H2O2-negative lactobacilli.
The subset of women enrolled in a large longitudinal cohort study who had Chlamydia trachoinatis (n = 13), bacterial vaginosis (n = 105), yeast vaginitis (n = 15), or mucopurulent cervicitis (n = 47) were compared with 93 women without genital infection from the same population. The effect of various treatment regimens on lactobacilli was evaluated.
Use of doxycycline, azithromycin, clotrimazole, and fluconazole had little effect on vaginal colonization by Lacto-bacillus. Use of oral or vaginal metronidazole led to an increase in Lactobacillus, which persisted 1 month after therapy. Intravaginal clindainycin use caused a decrease 1 week post-therapy, but at 1 month, levels of lactobacilli were similar to those in the metronidazole treatment group. Women treated with oral ampicillin had a modest increase in Lactobacillus levels.
Use of antimicrobial agents for treating vaginitis and cervicitis do not cause a decrease in vaginal colonization by Lactobacillus, which is detectable 1 week to 1 month after treatment.
