Bacterial vaginosis is a polymicrobial infection with a collection of bacteria. This bacteria will be specific to the woman involved, and cannot be determined except by testing though certain bacteria are typically found. The most common bacteria involved in BV produce enzymes that break down cervical mucous and invade membranes of cells. This can weaken the membranes, and increase the risk of premature rupture.
Common bacteria found in BV include:
- Gardnerella vaginalis
- Mycoplasma genitalium
- Bacteroides (Prevotella) spp.
- Mobiluncus spp.
- Mycoplasma hominis
- Fusobacterium spp.
- Non-viridans group Streptococci
