Biocenosis of the vaginal tract in patients with fertility on the background of chronic endometritis

The objective: to determine the microbiota profile of vagina, cervical canal and endometrium by chronic endometritis (CE) in patients with a history of infertility.Materials and methods. A prospective study and clinical-laboratory analysis of the microbiocenosis of the vagina, cervical canal and uterine cavity in women with CE and infertility in history was conducted. The 1st group included 100 women of reproductive age with CE and infertility, the 2nd group – 40 women of reproductive age without impaired fertility.The scope of research is pH-metry of vaginal secretions, assessment of vaginal microbiocenosis based on Gram-stained smear microscopy, polymerase chain reaction method, cultural research of vaginal secretions, study of the microflora of the cervical canal and the uterine body.Results. In women with CE and a history of infertility, normobiocenosis of the vagina was found in only 32 patients (32.0±3.1%). In other cases, bacterial vaginosis, vulvovaginal candidiasis, and bacterial vulvovaginitis were detected. Microscopy and PCR-diagnostics of secretions from the cervical canal and uterine cavity in women with CE determined Streptococcus agalactiae, Enterococcus faecalis, Chlamidia trachomatis, Ureaplasma urealyticum, Mycoplasma genitalium, HPV, Gardnerella, HSV 1st or 2nd types and CMV.Conclusions. A characteristic feature of the vaginal flora in chronic endometritis is a high level of dysbiotic changes combined with high rates of insemination by opportunistic flora. The microbiota of the cervical canal and endometrium during inflammatory processes of the endometrium is characterized by the predominance of obligate anaerobic microorganisms in the form of associations with viral infection, which are significantly more often (more than 2 times) detected in the endocervix compared to the endometrium.
