Abstract :
Violation of vaginal microbiocenosis with the development of bacterial vaginosis in women of reproductive age is manifested in an increase in the number of opportunistic microorganisms and contamination of habitats unusual for this type of bacteria, which serves as a signal for irreversible changes in the corresponding link of the ecosystem. The aim of this work was to study the qualitative and quantitative composition of the vaginal microflora in women of reproductive age with bacterial vaginosis. The study involved 34 patients and 20 apparently healthy women. In all patients, the qualitative and quantitative composition of the bacterial flora of the vagina was studied with using bacteriological methods. The studies carried out made it possible to establish the nature of microecological changes in the vaginal microbiocenosis in bacterial vaginosis, which consists in a decrease in the amount of lactoflora, an increase in the species richness of microflora, an increase in the proportion of anaerobic microorganisms and an increase in the persistent potential of the vaginal microflora. As a result of the analysis of the species characteristics of the biotopes of the reproductive tract in patients (n = 34) with bacterial vaginosis, it was noted that among aerobes, only one tenth were lactobacilli (7.55%). Conditionally pathogenic aerobic microorganisms accounted for 92.45% of strains, of which a large proportion (75.45%) were gram-positive cocci: staphylococci (CBS -20.74%, KPS- 5.66%), streptococci (11.31%) and enterococci (37.74%). Enterobacteriaceae were represented by E. coli strains (5.66%). The anaerobic microflora of the vagina is mostly represented by bacteroids (9.43%) and eubacteria (1.89%).
