STD Information » Bacterial Vaginosis

Overview

Bacterial vaginosis is a bacterial infection of the vagina. It is caused when other strains of bacteria (Bacteroides, Gardnerella vaginalis, Mobiluncus, and Mycoplasma hominis are common varieties found with bacterial vaginosis) outnumber the "good" bacteria that normally reside in the vagina. Doctors aren't sure what causes bacterial vaginosis, but it appears to be linked to multiple sexual partners, changing sexual partners, and douching.

How is Bacterial Vaginosis diagnosed?

In order to diagnose bacterial vaginosis, a physician will take a sample of vaginal fluid and look at it under a microscope. Both the presence of bacteria commonly associated with the condition and an absence of "good" bacteria are signs of bacterial vaginosis.

How is Bacterial Vaginosis treated?

Gonorrhea is easily treated with a single dose of the following antibiotics:

• Metronidazole
  Orally twice a day for seven days or topically twice daily for five days
• Clindamycin
  Orally twice a day for seven days or topically before bed for seven days

Recovery Time

Treatment takes between five and seven days, however, recovery may not be complete for a few days after that.

Sexual Activity

If you have bacterial vaginosis, your male sexual partners do not need to be treated. However, bacterial vaginosis can be spread between female sex partners; as such, they should be tested and treated. Additionally, sex should be avoided until both partners are free from infection. Re-infection is entirely possible with bacterial vaginosis; as such, it is advisable to take whatever precautions possible.

Prevention

As the causes of bacterial vaginosis are not clearly understood, it is difficult to determine prevention methods. The condition is more common among women who are sexually active and there appears to be a link between not using condoms and developing bacterial vaginosis. With that in mind, abstaining from sex or being monogamous and using condoms would be the best prevention methods. Additionally, as there is a link with douching, that should be avoided as well.
