[Frequency, diagnostic criteria and consequences of bacterial vaginosis in pregnant women].

Vaginal discharge based on changes in a vaginal ecosystem (decreasing number of Lactobacillus and increasing number of Mobiluncus spp., Gardnerella vaginalis, Prevotella spp., Mycoplasma hominis, Peptostreptococcus spp) appears to be a major cause of bacterial vaginosis. Bacterial vaginosis is associated with: preterm delivery, premature rupture of membranes, chorioamnionitis, amniotic fluid infection, endometritis, low-weight neonates. The role of natural microflora of vagina, the most important diagnostic criteria, epidemiology and immunological changes in pregnant women with bacterial vaginosis are discussed in the light of the recent publications.
