Bacterial vaginosis is a common condition, and studies have shown that approximately 29% of women in the US are affected
It is anaerobic gram-variable rod which can cause bacterial vaginosis in some women as a result of a disruption in the normal vaginal microflora which results in an overgrowth of normal bacteria in the vagina.

The resident anaerobic lactobacillus population in the vagina are responsible for the acidic environment. Once the anaerobes have supplanted the normal vaginal bacteria, prescription antibiotics with anaerobic coverage may have to be given to eliminate the Gardnerella vaginalis and allow the balance to be restored.
What causes bacterial vaginosis?
Researchers have had difficulty determining exactly what causes bacterial vaginosis. At present, it seems to be that a combination of multiple bacteria must be present together for the problem to develop. Bacterial vaginosis typically features a reduction in the number of the normal hydrogen peroxide-producing lactobacilli in the vagina. Simultaneously, there is an increase in concentration of other types of bacteria, especially anaerobic bacteria (bacteria that grow in the absence of oxygen). As a result, the diagnosis and treatment are not as simple as identifying and eradicating a single type of bacteria. Why the bacteria combine to cause the infection is unknown.
A few antibiotic remedies are routinely used. Metronidazole (Flagyl) taken by either oral (pill) form or by vaginal metronidazole gel (Metrogel) is an effective cure.
