dc.description.abstractEnObjectives: Dysbiotic bacterial communities within the vagina are associated with Chlamydia trachomatis infection. We compared the effect of treatment with azithromycin and doxycycline on the vaginal microbiota in a cohort of women with a urogenital C. trachomatis infection randomly assigned to one of these treatments (Chlazidoxy trial). Methods: We analysed vaginal samples from 284 women (135 in the azithromycin group and 149 in the doxycycline group) collected at baseline and 6 weeks after treatment initiation. The vaginal microbiota was characterized using 16S rRNA gene sequencing and classified into community state types (CSTs). Results: At baseline, 75% (212/284) of the women had a high-risk microbiota (CST-III or CST-IV). A crosssectional comparison 6 weeks after treatment showed that 15 phylotypes were differentially abundant, but this difference was not reflected at the CST (p 0.772) or diversity level (p 0.339). Between baseline and the 6-week visit, a-diversity (p 0.140) and transition probabilities between CSTs were not significantly different between the groups, and no phylotype was differentially abundant. Discussion: In women with urogenital C. trachomatis infection, the vaginal microbiota does not seem to be affected by azithromycin or doxycycline 6 weeks after treatment. Because the vaginal microbiota remains susceptible to C. trachomatis infection (with CST-III or CST-IV) after antibiotic treatment, women remain at risk of reinfection, which could originate from unprotected sexual intercourse or untreated anorectal C. trachomatis infection. This last consideration advocates for the use of doxycycline instead of azithromycin because of its higher anorectal microbiological cure rate.
