“…Further studies on the relationship between vaginal microecological imbalance and the expression of serum inflammatory factors and GBS infection can provide more effective prevention and treatment strategies for maternal health, and help to improve pregnancy outcomes. Compared with other experimental studies (27)(28)(29)(30)(31), this experiment analyzed the proportion of vaginal microecological imbalance and the expression of serum inflammatory factors in pregnant women with GBS infection and those without GBS infection. It concluded that GBS infection can increase the probability of vaginal microecological imbalance and the expression level of serum inflammatory factors in pregnant women, which will lead to an increase in adverse pregnancy outcomes.…”
