Bacterial vaginosis (BV) is a polymicrobial biofilm vaginal syndrome characterized by a high prevalence, recurrence rate and associated complications, including preterm birth, infertility and a higher risk of sexually transmitted infections. Traditional diagnostic methods used to detect the disease do not provide complete information on the morphology, number, and spatial arrangement of microorganisms associated with BV. Fluorescence in situ hybridization (FISH) combines the accuracy of molecular genetics with the informative power of microscopy to visualize the relationships between bacteria in their natural microhabitat, such as the biofilm in BV. The persistence of biofilm composed of BV-associated microorganisms is one of the most likely pathways for recurrence and is an important diagnostic marker for the disease.  The review of the literature presents the history of the use of FISH, outlines its basic principles and demonstrates its advantages in the diagnosis of bacterial vaginosis, especially its recurrent forms.
Conclusion: The use of the FISH method may not only change the understanding of BV pathogenesis, but it can also identify the etiological agent in each particular case, diagnose biofilm/non-biofilm vaginosis by determining the spatial relationship of bacteria to each other and to epithelial cells, predict the recurrence of the disease and choose the appropriate therapy.
