Bacterial vaginosis is a common vaginal infection, occurring in 30% of women of childbearing age in the United States, and recurring in 20% to 30% of these women after initial treatment. 1 The condition typically is caused by an overgrowth of normal vaginal flora, such as the Gram-negative bacterium Gardnerella vaginalis, and is seen concurrently with a diminished amount of normal vaginal lactobacilli. 2 Because vaginal lactobacilli help to maintain a normal vaginal pH, a diminished lactobacillus level allows for overgrowth of anaerobes responsible for the symptoms associated with bacterial vaginosis. Other organisms that can cause bacterial vaginosis include Atopobium vaginae, Megasphaera phylotype 1 and 2, Leptotrichia aminionii, Mobiluncus spp.,
