[Bacterial vaginitis: general overview].

Abstract

Bacteria are the most frequently detected agents in women, clinically complaining of vaginal discharge. The studies have shown that the vaginal microflora of women with bacterial vaginitis have altered from Lactobacillus spp. to various anaerobic bacteria. Gardnerella vaginalis is found in vaginal flora of women with bacterial vaginitis as well as in healthy women, while anaerobic bacteria such as Mobiluncus and Prevotella are the causative agents for bacterial vaginosis. For the laboratory diagnosis of bacterial vaginitis, direct microscopy is one of the most commonly used methods, and for this purpose cervicovaginal smears are examined by staining Papanicolaou and Gram stains. Because of the demonstration of bacterial vaginitis in association with the obstetric diseases such as preterm labor and postpartum endometritis, is a risk factor, its importance has increased recently. In this review article, the microorganisms that cause bacterial vaginitis, their biological characteristics, and the diagnostic laboratory methods of infection, have been discussed.
