Abstract:

Genital tract infection is an important risk factor of preterm birth，and their relationship varies with gestational age.Except for the vagina，the cervix and placenta have independent bacterial colonization；however，the association between preterm birth and the microbiome of the cervix and placenta needs further study.Currently，there is no consensus on whether antibiotics should be used in genital tract infection during pregnancy.

Key words: preterm birth, genital tract infection

摘要：

生殖道感染是早产的重要因素，两者的关系随着孕周而改变。除阴道外，宫颈和胎盘都有其独立的菌群定植，但宫颈和胎盘的微生物群与早产之间的关系仍需进一步研究。目前对于抗生素的使用仍未有统一意见。
