Vaginal microbiota composition

Vaginal microbiota composition refers to the distribution and balance of microbial inhabitants within the vagina, primarily bacterial species, which form discrete community state types (CSTs) dominated either by specific Lactobacillus species or by diverse anaerobic bacteria. This ecosystem is dynamic, influenced by hormonal changes, age, sexual activity, and interventions, and its balance is crucial for genital tract health. Imbalances (dysbiosis) are linked to increased risk of infection, adverse reproductive outcomes, and broader health implications. Unlike individual molecular targets, vaginal microbiota composition is an ecological index rather than a conventional drug target or receptor.
