The most serious consequences of B. Gardneri are not clinically clear, but infection with B. Gardneri indicates bacterial vaginitis, which if left untreated may cause diseases such as endometritis and pelvic inflammatory disease, and women in pregnancy can experience preterm labor and other phenomena. Gardnerella bacteria generally parasitize and proliferate in the female reproductive system, eventually leading to bacterial vaginitis, which may manifest as increased vaginal discharge, vulvar itching or burning sensation and other symptoms. If bacterial vaginitis is not controlled in time, it is prone to cause endometritis, pelvic inflammatory disease and other concurrent diseases, often manifested as lower abdominal pain and other symptoms. In addition, for pregnant women, bacterial vaginitis can also lead to premature rupture of membranes, mainly manifested as a sudden sensation of more liquid out of the vagina; there can also be the phenomenon of preterm labor, which is mostly manifested as abdominal pain, a little vaginal bleeding and other symptoms. Therefore, infection with Gardnerella should be promptly consulted and treated in hospital to avoid adverse effects.
