The research of our group in 2017 showed that transplantation of healthy rat vaginal microbiota into the vagina of BV model rats restored the morphology of uterine tissue and reduced the serum inflammatory factors such as IL-6, IL-8, and TNF-α, showing obvious recovery effects on vaginal infections caused by dysregulation of vaginal microbiota. This evidence concerns the gene CXCL8 and bacterial vaginosis.
