The normal vaginal, or resident, flora is complex and easily includes over a dozen different organisms, many of them potential pathogens. The quantitative nature of the vaginal flora also is a factor in development of symptoms. This complex milieu is further varied by nature's changes over the years from birth to menopause. Artificial changes occurring as the result of contraceptive measures may also disrupt the resident vaginal flora. Each patient may be her own control, and the balance that leads to an asymptomatic state may vary from individual to individual. An understanding of the normal situation may be the best guide to diagnosing abnormal conditions and directing appropriate therapy.
正常的阴道菌群，即常住菌群，非常复杂，通常包含十几种不同的微生物，其中许多都可能是潜在病原体。阴道菌群的数量特征也是引发症状的一个因素。从出生到绝经的多年间，随着自然变化，这种复杂的环境会进一步改变。避孕措施导致的人为变化也可能扰乱常住阴道菌群。每个患者都可以作为自身对照，而导致无症状状态的平衡可能因人而异。了解正常情况可能是诊断异常状况并指导适当治疗的最佳指南。
