Women’s Health
Women’s health, a vital aspect of medical science, encompasses various conditions unique to women’s physiological makeup. Historically, women were often excluded from clinical research, leading to a gap in understanding the intricacies of women’s health needs. However, recent advancements have highlighted the significant role that the microbiome plays in these conditions, offering new insights and potential therapies. MicrobiomeSignatures.com is at the forefront of exploring the microbiome signature of each of these conditions to unravel the etiology of these diseases and develop targeted microbiome therapies.

Bacterial Vaginosis
Bacterial Vaginosis
Bacterial vaginosis (BV) is caused by an imbalance in the vaginal microbiota, where the typically dominant Lactobacillus species are significantly reduced, leading to an overgrowth of anaerobic and facultative bacteria.

What was Reviewed?
This narrative review examined the role of biofilms in bacterial vaginosis (BV), focusing on their contribution to treatment resistance and recurrence. The authors synthesized evidence from clinical studies and trials to evaluate the limitations of current antibiotic therapies and explored emerging solutions, such as biofilm-disrupting agents and probiotics, to improve BV management.
Who was Reviewed?
The review analyzed data from diverse patient populations in clinical studies, including women with recurrent BV. It incorporated findings from trials investigating biofilm-targeted therapies, such as enzymatic disruptors (e.g., dispersin B) and probiotics (e.g., Lactobacillus crispatus), to assess their efficacy in restoring vaginal microbiota balance.
What were the most Important Findings?
The review highlighted that BV-associated biofilms, primarily formed by Gardnerella vaginalis and Atopobium vaginae, shield pathogenic bacteria from antibiotics, driving recurrence. Major microbial associations (MMA) included polymicrobial anaerobic communities displacing protective Lactobacillus species. Probiotics and biofilm-disrupting agents (e.g., boric acid, Astodrimer gel) showed promise in clinical trials, with probiotics delaying recurrence by 51% and Astodrimer gel significantly reducing recurrence rates. Notably, Lactobacillus crispatus-based therapies were emphasized for restoring vaginal acidity and inhibiting biofilm formation.
What are the Implications of this Review?
The findings emphasize the need to shift from antibiotic-only approaches to multimodal strategies targeting biofilms. Clinicians should consider adjunct therapies like probiotics and biofilm disruptors to enhance treatment efficacy and reduce recurrence. The review also calls for further research into vaginal microbiome transplantation (VMT) and personalized therapies to address biofilm resilience.
