Adhesion of group B streptococci to epithelial cells of the human vagina proved to be type dependent and to fluctuate during the menstrual cycle with a maximum near the time of ovulation. Oral contraception completely abolished the observed cyclic changes. Reduced serum levels of luteinizing hormones (less than 5 mIU/ml) and of follicle-stimulating hormone (less than 10 mIU/ml) were associated with a 10-fold reduction in adhesion of B streptococci to vaginal cells.
B族链球菌对人阴道上皮细胞的黏附被证明具有类型依赖性,且在月经周期中会波动,在排卵时附近达到最大值。口服避孕药完全消除了观察到的周期性变化。促黄体生成素血清水平降低(低于5 mIU/ml)和促卵泡激素血清水平降低(低于10 mIU/ml)与B族链球菌对阴道细胞黏附减少10倍有关。
