Abnormal vaginal microflora in the first trimester of pregnancy is a risk factor for miscarriage. Opportunistic microorganisms predominate among microorganisms causing microflora disturbance. Aim. The aim of the study was to evaluate the vaginal microflora in the first trimester of pregnancy in women having history of pregnancy loss. Matherials and Methods. Real-time polymerase chain reaction, microscopic and cultural methods were used to examine 60 pregnant women having history of pregnancy loss and 10 pregnant women with uncomplicated obstetric history. Results. Disorders of the vaginal microflora were observed only in women having history of pregnancy loss. The lactoflora in both groups was shown to consist most frequently of 3 Lactobacillus species: Lactobacillus crispatus, L. jensenii, and L. iners. However, the species L. iners were detected only in the group of women with history of pregnancy loss. Non-Lactobacillus microbiota was significantly more often observed in pregnant women having history of pregnancy loss. Facultative and obligate anaerobes were detected in both groups. The concentration of Ureaplasma spp. and Mycoplasma hominis in women in both groups had no significant differences. Conclusions. The results of this study indicate that abnormal microbiota is more often observed in women having history of pregnancy loss.of pregnancy in women having history of pregnancy loss.

Disorders of the vaginal microflora were observed only in women having history of pregnancy loss. The results of this study indicate that abnormal microbiota is more often observed in women having history of pregnancy loss. Относительно недавние исследования с использованием молекулярных методов показали преобладание определенных видов лактобацилл во влагалище у здоровых женщин: Lactobacillus crispatus, L. jensenii, L. gasseri и L. iners [9, 10].
