Other STIs get transmitted regardless of your reproductive anatomy.
Still, sexual activity can put you at risk for BV. Sexual activity alone doesn’t seem to cause overgrowths of Gardnerella bacteria or BV.
But people who are not sexually active can have unhealthy levels of Gardnerella and BV, too.
People with new sex partners or multiple sex partners often have unhealthy levels of Gardnerella, and these overgrowths are associated with BV. People who are not sexually active get BV.This isn’t the case with other common STIs, where the presence of the bacteria means that you have an infection. Healthy vaginas have Gardnerella bacteria in them. Having Gardnerella bacteria doesn’t mean you have an infection.Gardnerella isn’t considered a sexually transmitted bacteria, like the bacteria that cause gonorrhea, syphilis or chlamydia, for a few reasons: But it’s a bacteria that’s most likely transmitted sexually. An imbalance in your vaginal flora causes BV. In this environment, Gardnerella starts to multiply, and other bacteria begin to cling to the Gardnerella bacteria and grow, too. Not having enough lactobacilli bacteria causes your vaginal PH to increase to 4.6 or more, so that your vagina isn’t acidic enough. Lactobacilli bacteria help keep your vagina acidic. People with BV have too little lactobacilli bacteria in their vaginas and too much Gardnerella bacteria. But the amount of two different kinds of bacteria in your vagina lactobacilli bacteria and Gardnerella bacteria – is key. You get BV when the delicate balance of bacteria that keeps your vaginal flora healthy becomes disturbed. And having too much Gardnerella in your vaginal fluid is a sign that you have BV. Is Gardnerella the same as bacterial vaginosis (BV)? But Gardnerella isn’t the same as BV, and it isn’t considered a sexually transmitted bacteria (at least not officially). And sometimes Gardnerella and BV both are mistaken for STDs or sexually transmitted infections (STIs). Gardnerella (a bacteria) is often confused with BV (a specific kind of vaginal infection). What are the common conditions and disorders associated with Gardnerella vaginalis? Having the right amount of Gardnerella and lactobacillus means that your vaginal flora is in balance and infection-free. Lack of lactobacillus or the wrong composition of lactobacillus creates an imbalance in the presence of Gardnerella, leading to BV. Having too much Gardnerella bacteria is a sign of BV. In other words, Gardnerella's purpose depends on how much you have of it. When the acidity levels drop, too much Gardnerella grows, and that’s when an infection can occur. The bacteria that make up your vaginal flora, including Gardnerella, work to maintain this level of acidity, which is just the right amount of acid for fighting infection. It’s considered to have a moderate amount of acid. A healthy vagina has a PH range of 3.8-4.5. We now know that Gardnerella plays a role in maintaining a healthy PH, or a healthy amount of acidity, in your vaginal fluid. However, Gardnerella is isolated in the majority of cases. BV is caused by many other bacteria like atopobium vaginae and megasphera. This means that Gardnerella alone isn’t to blame for vaginal infections. People with vaginal infections have Gardnerella bacteria in their vaginas, but people without vaginal infections have Gardnerella, too. Since then, research has shown that things aren’t so straightforward. The thinking that Gardnerella led to infection was so accepted that people referred to what we now know as BV, a specific kind of vaginal infection, as simply “Gardnerella vaginosis.” People named the infection after the bacteria they thought caused it. When Gardnerella was first discovered in 1955, it was thought of as a “bad” bacteria that caused vaginal infections. What is the purpose of Gardnerella vaginalis?
