It is usually not called bacterial vaginitis, but bacterial vaginosis, and about 10-40% of patients with bacterial vaginosis have no clinical symptoms. Some patients may present with increased vaginal discharge that is yellowish in color and accompanied by a foul odor. Occasionally, some patients may experience itching or burning sensation, and the symptoms may worsen after intercourse. For bacterial vaginosis, during a gynecological examination the vaginal walls are usually not congested, and the leukorrhea seen is grayish-white, uniform in color, thin, very copious, and adherent to the vaginal walls, and can be removed with a gentle wipe of a cotton swab. For bacterial vaginosis, treatment is mainly with anti-anaerobic drugs such as metronidazole.
