The aim of the study: was complex assessment of different types of vaginal biocenosis according to the results of different methods, determining the most optimal of them.

Materials and methods. The study included 143 patients aged 21 to 39 years; 123 women were pregnant at different gestational ages – I clinical group, in II clinical group consisted of 20 nonpregnant women of childbearing age with normocenosis of the vagina. Research in the group I was randomized with informed consent to participate in research. Inclusion criteria: age not more than 39 years, absence of severe forms of somatic pathology, the absence of references to pharmacological correction of inflammatory diseases of the genital organs in the last 6 months. Map primary observations were filled on the day of treatment to the doctor. Requirements for fence material: the lack of training and sexual intercourse within the last 3 days. Exclusion criteria from the study: presence of sexually transmitted infections, in the acute phase.

Results. Were analyzed the results of a study of the vaginal microbiota and women's groups. The data obtained in the I clinical group are V types of microbiota. The basis of the type of the subgroup belongs to the pH value of vaginal secretions. Took note of the content of lactobacilli, pathogenic and conditionally pathogenic aerobic and anaerobic flora; the concentration of Candide; white blood cell count.

Conclusion. 1. The pH of the vaginal secretions can be used as an indicator of the condition of the vaginal biotope, it is consistent with the quantitative assessment of the vaginal microbiota and lactobacilli in it.

2. PH 4,0–4,7 can be considered an indicator of the norm. pH greater than 4.7 indicates the violation of the ecological community is clearly reflected in the increase in the number of complications of gestation, a higher number of inflammatory diseases of somatic nature.

3. The pH of the vaginal secretions can be used for screening, monitoring biotope of the vagina during pregnancy, before childbirth, caesarean section without additional biological support. The method can be considered optimal in the parameters «informative», «accessibility», «price».

Key words: pH of vaginal secretions, vaginal biotope, pregnancy.
