Baseline Study of Vaginal Microbiota in Healthy Chinses Female Population

The reproductive tract microecology is an important part of the human microbial system. Microorganisms and the host reproductive tract environment form a stable symbiotic relationship. When pathogens invade or microecology imbalance，it can lead to serious reproductive tract infection.Reproductive tract infection is one of the most common disease among women，and it is a global social and public health problem. Reproductive tract infection is characterized by high morbidity, low cure rate and high recurrence rate.Data from the studies shows that 40% of Chinese women suffer from reproductive tract infections of varying degrees, that is, at least 200 million. Long-term chronic infections can lead to serious consequences such as infertility, tumor, abortion and premature birth. At present, the diagnostic classification of reproductive tract infection is mainly divided into Aerobic vaginitis（AV), Bacterial vaginosis（BV), Vulvovaginal candidiasis（VVC) and Trichomonas vaginitis（TV). The reproductive tract microbiota is complex, but the clinical classification is relatively simple, which makes the treatment lack of precision. More precise treatment，permanent cure and reducing the recurrence rate are the top priorities in the field of medical and health.
