Microbiome structure in healthy and pregnant women and importance of vaginal dysbiosis in spontaneous abortion.

The vaginal microbiome of healthy women is dominated by spp. A variety of illnesses, such as vaginosis, sexually transmitted infections (STIs), failed implantation, premature birth (PTB), and preterm pre-labor membrane rupture, are brought on by an unbalanced microbiota. Pregnancy is associated with a decrease in the metabolic capacity of the vaginal resident microbiome, which is consistent with a change to a less complex -dominated microbiome.
