Bacterial vaginosis (BV) is the most common cause of abnormal vaginal discharge in women of childbearing age. The reported prevalence is approximately 12% in women attending gynecology or antenatal clinics in the United Kingdom.<sup>8 Hay P.E., Lamont R.F., Taylor-Robinson D. , et al.

Treatment is effective in the short term, but BV recurs in 20% to 30% women within one month of treatment.<sup>14 Larsson P.G. Treatment of bacterial vaginosis Int J STD AIDS 1992 ;  3 : 239

The main reason for trying to prevent relapse of BV is to help symptomatic women and their partners who may also be offended by it. However, in addition, BV is a risk factor for miscarriage and preterm birth in pregnant women and infectious morbidity following cesarean section or gynecologic surgery. It may also predispose women to acquire sexually transmitted infections including HIV.<sup>20 Sewankambo N., Gray R.H., Wawer M.J. , et al.
