Bacterial vaginosis (BV) is an infection caused by a change in the vaginal flora, which refers to the community of organisms that live in the vagina.[14] It is the most common cause of pathological vaginal discharge in women of childbearing age and accounts for 40–50% of cases.[15] In BV, the vagina experiences a decrease in a bacterium called lactobacilli, and a relative increase in a multitude of anaerobic bacteria with the most predominant being Gardnerella vaginalis.[16] This imbalance results in the characteristic vaginal discharge experienced by patients with BV.[14] The discharge in BV has a characteristic strong fishy odor, which is caused by the relative increase in anaerobic bacteria.[1] The discharge is typically thin and grey, or occasionally green.[14][16] It sometimes is accompanied by burning with urination.
