The objective of the research was to study genital mycoplasma contribution to the development of reproductive disorders. Mycoplasma detection rate in genital smears of pregnant women of Khabarovsk was studied by a polymerase chain reaction (PCR) method. Ureaplasma (urealyticum+parvum) was detected in 56.3% of cases; Mycoplasma hominis in 7.5% of cases, Mycoplasma genitalium in 0% of cases. Genital mycoplasmas were detected in chorionic and fetal tissue samples in early-term spontaneous miscarriage cases, suction biopsies in women with recurrent miscarriage, tissue samples in elective abortions, placental samples of women whose pregnancy ended in preterm delivery, and placental samples of women who gave birth to children at term. Ureaplasma (urealyticum+parvum) DNA was detected in 11.9%, 18.8%, 1.4%, 32.6%, and 25.0% of cases, respectively; Mycoplasma hominis DNA in 7.4%, 12.5%, 2.6%, 2.3%, and 0% of cases, respectively; Mycoplasma genitalium DNA in 5.2%, 6.3%, 1.4%, 2.3%, 0%, respectively. Genital mycoplasmas were detected in autopsy material of children who had died in neonatal and postnatal periods. Relationship between mycoplasma concentration in vaginal flora of pregnant women and preterm delivery was identified using real-time PCR. Mycoplasma detection rate in reproductive pathologies was found to be significantly higher than in control groups. The results of the study favor the view of etiopathogenetic role of mycoplasmas in development of complications and outcomes of pregnancy.
