PATHOGENS

  • Bacterial vaginosis (BV) appears to represent a disruption of normal vaginal flora with altered relative concentrations of various microorganisms including depletion of H2O2 producing lactobacilli and proliferation of anaerobic Gram negative and Gram positive bacteria such as:
    • Gardnerella vaginalis
    • Mobiluncus species
    • Mycoplasma hominis
    • Prevotella species
    • Atopobium vaginae
    • Other: Leptotrichia/Sneathia spp., Megasphaera spp. and BVAB-1, BVAB-2, and BVAB-3 (all Clostridiales order bacteria)
  • There is an absence of inflammation with a dense biofilm present, G. vaginalis predominates over other species.
