Microbial pathogens associated with bacterial vaginosis (BVAB) (BVAB)

Microbial pathogens associated with bacterial vaginosis (BV) represent a diverse group of anaerobic and facultative bacteria that displace healthy, lactic acid-producing Lactobacillus species in the vaginal microbiome (StatPearls, 2023). Key organisms include Gardnerella vaginalis, Atopobium vaginae, and various species of Prevotella and Mobiluncus, which often coexist within a structured polymicrobial biofilm on the vaginal epithelium (Journal of Infectious Diseases, 2016). This shift in microbial composition leads to increased vaginal pH, the production of malodorous volatile amines, and the degradation of the protective mucosal barrier (Clinical Microbiology Reviews, 2016). Therapeutic strategies primarily utilize broad-spectrum antibiotics such as metronidazole and clindamycin to reduce the load of these anaerobic pathogens (CDC, 2021). However, these treatments often lack specificity, leading to the unintended depletion of beneficial lactobacilli and contributing to high rates of infection recurrence (Nature Reviews Microbiology, 2018). Understanding the synergistic interactions within these microbial communities is essential for developing more targeted therapies that can restore a healthy vaginal ecosystem (The Lancet, 2019).
