Bacterial Vaginosis (BV)
Bacterial vaginosis (BV) is the most common vaginal infection. BV is sometimes also called bacterial vaginitis, or bacterial vaginal infection and is not really a vaginal infection. It is really an imbalance of the normal bacteria in the vagina. A healthy vagina normally contains many bacteria; some of the "good" bacteria are called Lactobacillus crispatus and Lactobacillus jensenii. These specific types of Lactobacillus bacteria produce hydrogen peroxide that prevents preventing other "bad" vaginal bacteria (including Gardnerella vaginalis, Mobiluncus, Bacteroides, and Mycoplasma) from multiplying to a level where they cause symptoms. As the number of "good" bacteria decrease, it allows more "bad" bacteria to gain a foothold and multiply. These "bad" bacteria produce toxins which affect the body's natural defenses and make it more difficult for the "good" bacteria to re-establish themselves. |
