Back to Health A to Z. Bacterial vaginosis BV is a common cause of unusual vaginal discharge. The most common symptom of bacterial vaginosis is unusual vaginal discharge that has a strong fishy smell, particularly after sex.
Bacterial vaginosis BV is a common yet poorly understood condition, in which the balance of bacteria inside the vagina becomes disrupted. If you have the condition, your discharge may:. BV isn't serious for the vast majority of women, although it may be a concern if symptoms of BV develop in pregnancy and you have a history of pregnancy-related complications.
The vaginal flora are the bacteria that live inside the vagina. The normal vaginal flora are dominated by various lactobacillus species. Lactobacilli help to keep the vagina healthy by producing lactic acid, hydrogen peroxide, and other substances that inhibit the growth of yeast and other unwanted organisms.
Bryan Larsen, Gilles R. The microbiological flora of the lower female genital tract provides a dynamic, complex example of microbial colonization, the regulation of which is not fully understood. When an exogenous bacterial species, with its array of virulence factors, is introduced into the host, disease does not always occur.
Bacterial vaginosis is a type of vaginal inflammation caused by the overgrowth of bacteria naturally found in the vagina, which upsets the natural balance. Women in their reproductive years are most likely to get bacterial vaginosis, but it can affect women of any age. The cause isn't completely understood, but certain activities, such as unprotected sex or frequent douching, increase your risk.
But your gut is not the only place where bacteria thrive in the body. And just like having the right healthy bacteria in the gut is important, having the right bacteria in the vagina can have an effect on health, too. One type of bacteria found in some vaginas is from the same genus as the bacteria in the yogurt in your refrigerator: lactobacillus.
The community of bacteria in the vagina that is considered "healthy" for a woman can vary a lot between individuals, a new study suggests. The finding is contrary to the prevailing idea that some vaginal microbes are nearly universally good for a woman's health while others are bad. For example, doctors have said women need high levels of Lactobacillus bacteria, which produce lactic acid, in the vagina.
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.
