Bacterial vaginosis BV is the most common vaginal infections in women of reproductive age and one of the most misunderstood. While it is not considered a sexually transmitted disease STD , BV is associated with the same risk factors as chlamydia , gonorrhea, and trichomoniasis. In fact, scientists aren't even entirely sure which mechanisms give rise to BV or why some women are prone to the infection and others aren't. What we do know is that, whatever the underlying cause, BV is the result of an imbalance in the vaginal flora in which healthy bacteria are depleted, allowing unhealthy ones to proliferate. Bacterial vaginosis is not considered an STD because the infection is not caused by a foreign pathogen such as a virus like HIV or a bacterium like syphilis. Instead, the infection occurs when certain "bad" bacteria commonly found in the vagina are given the opportunity to thrive.

What Is It? Bacterial vaginosis BV is a condition in which the normal balance of bacteria in the vagina is disrupted and replaced by an overgrowth of certain bacteria. Symptoms may include discharge, odor, itching or irritation, but often there are no symptoms. Bacterial vaginosis BV is the most common of three vaginal infections that fall under the category known as vaginitis.
Causes and Risk Factors of Bacterial Vaginosis
The sequencing data for this project were deposited in the MG-RAST server and are publicly available under project number Behavioral data is required to be securely stored in keeping with University of Melbourne Human Research and Ethics Committee requirements. To examine the influence of sexual activity on the composition and consistency of the vaginal microbiota over time, and distribution of Gardnerella vaginalis clades in young women. Fifty-two participants from a university cohort were selected.
Bacterial vaginosis is the most common cause of abnormal vaginal odor and discharge. It is caused by a change in the type of bacteria found in the vagina. Normally, bacteria belonging mostly to the Lactobacillus family live harmlessly in the vagina and produce chemicals that keep the vagina mildly acidic. In bacterial vaginosis, Lactobacillus bacteria are replaced by other types of bacteria that normally are present in smaller concentrations in the vagina. Scientists do not fully understand the reason for this change.
