What is Gardnerella?

Gardnerella is a bacteria that infects the genital tract of women and causes a change in the bacterial balance, or rather, imbalance. This imbalance can cause a condition known as bacterial vaginosis (BV).

The bacteria can also be passed on to men by women during sexual intercourse.

Most reported cases of Gardnerella infections are related to sexual activities, women who have never had vaginal intercourse can also acquire the infection. Therefore, it is important to get tested if you suspect you may have BV.

How can I catch Gardnerella?

Gardnerella can be spread by sexual contact and is most frequently observed as occurring from women to men and from women to women. It has not been definitively established that men can transmit a Gardnerella infection to women.

BV develops when the natural balance of bacteria in the vagina is disrupted. This imbalance can occur due to sexual contact, such as a new partner or not using a condom, or non sexual reasons, such as changing soap or using certain contraceptive devices.

What are the symptoms and signs of Gardnerella/BV in men and women?

Up to 50% of people who are infected with Gardnerella often have no symptoms. When there are symptoms, in women these can include an unusual watery vaginal discharge (often grey, green or yellowish in colour, thinner than the "cheesy," thick discharge seen in vaginal yeast infections), a "fishy" odour, and itching or burning when urinating.

In men, symptoms may include itching or burning on urination, or other urinary or penile discomfort.
