阴道是一个闭合的体腔，其深部几乎没有空气，所以寄生菌是以厌氧菌或兼性厌氧菌的菌株为主，正常阴道内厌氧菌与需氧菌之比为２∶１至５∶１［１］。当阴道内菌群失调时乳酸杆菌的优势地位则被大量的加德纳菌或混合性厌氧菌群所代替，尤其是厌氧菌可增加上千倍，病原体数量在
The vagina is a closed body cavity, the depth of almost no air, so the anaerobic bacteria or facultative anaerobic strains of the main normal anaerobic bacteria and aerobic bacteria ratio of 2: 1 to 5 : 1 [1]. When vaginal flora dysbacteriosis Lactobacillus was a large number of Gardnerella or mixed anaerobic bacteria replaced, in particular, anaerobic bacteria can increase thousands of times, the number of pathogens in
