Gardnerella

Gardnerella is a type of bacterial infection that affects the vagina and is caused by the bacterium Gardnerella vaginalis. It is also known as bacterial vaginosis (BV) or gardnerella vaginitis.

What is Gardnerella?

Gardnerella vaginalis is a naturally occurring bacteria in the vagina, but when it overgrows, it can cause an infection. The exact cause of this overgrowth is not fully understood, but it is thought to be related to an imbalance of the normal bacterial flora in the vagina.

Symptoms of Gardnerella

The symptoms of gardnerella may include:

  • A thin, white or gray vaginal discharge with a strong fishy odor

  • Redness and swelling of the vagina and vulva
  • Painful urination

Treatments for Gardnerella

The treatment for gardnerella usually involves antibiotics, which can be prescribed by a doctor. The most common treatments are:

  • Metronidazole (Flagyl): This is an oral antibiotic that is taken for 5-7 days.
  • Clindamycin (Cleocin): This is a cream or gel that is applied to the vagina for 3-7 days.
  • Tinidazole (Tindamax): This is an oral antibiotic that is taken for 2-5 days.

Home Remedies and Prevention

In addition to medical treatment, there are some home remedies and prevention methods that can help to alleviate symptoms and prevent future infections:

  • Practicing good hygiene: Wipe from front to back after using the bathroom, and avoid using scented soaps or douches.

Diagnosis of Gardnerella

Gardnerella is typically diagnosed through a physical exam and laboratory tests, including:

  • Pelvic exam: A doctor will perform a pelvic exam to look for signs of infection, such as redness and swelling.
  • Vaginal discharge test: A sample of vaginal discharge may be taken and sent to a lab for testing.
  • pH test: A pH test can help to determine if the vagina is too alkaline, which can indicate an infection.
