Abstract

Studying microbiota of different urogenital tract habitats in healthy postmenopausal women is of practical importance in deciding on the appropriateness of correction of dysbiotic disorders. The aim of this study was to examine the vaginal and urine microbiota of healthy postmenopausal women. The study included 20 healthy postmenopausal women (mean age 59,0±2,1 years). Duration of menopause in all subjects was more than 8 years. Bacteriological testing of urine and vaginal specimen was carried out on the extended media (15) for cultivating facultative anaerobic bacteria (FAB) and nonclostridial anaerobic bacteria (NAB) and included PCR of midstream morning urine. Among FAB in the urine and vagina dominated coagulase-negative staphylococci and NAB. Bacterial patterns of studied habitats turned out to be similar in many respects. In the urine Megasphaera spp., Veillonella spp., Prevotella spp., Mobiluncus spp., Fusobacterium spp. were found, whereas in the vagina these microorganisms were not present. Cluster analysis revealed no significant differences in the concentration of the same microorganisms isolated from the urine and vagina. When comparing the frequency of microorganism detection in urine by bacteriological method and by PCR, bacterial patterns were identical in 56% of cases.
