The Relation of Preterm Birth and Microbiota

One hundred trillion of symbiotic bacterial cells in every human being make up the human microbiota. Microbiota protects tissues from antigens and pathogens by increasing mucosal barrier resistance. In pregnancy there are changes in the female body, especially in the vaginal microbial. In studies, it has been reported that this alteration inhibits pathogenesis by the secretion of antibacterial bacteriocins such as lactic acid, which can maintain acid pH. The impaired vaginal environment is associated with pregnancy complications, especially with the risk of preterm birth. This study discusses the relationship between preterm birth and microbiota
