The female genital tract microbiota is part of a complex ecosystem influenced by several physiological, genetic, and behavioral factors. It is uniquely linked to a woman's mucosal immunity and plays a critical role in the regulation of genital inflammation. A vaginal microbiota characterized by a high abundance of lactobacilli and low overall bacterial diversity is associated with lower inflammation. On the other hand, a more diverse microbiota is linked to high mucosal inflammation levels, a compromised genital epithelial barrier, and an increased risk of sexually transmitted infections and other conditions. Several bacterial taxa such as spp., spp., spp., and spp. are well known to have adverse effects; however, the definitive cause of this microbial dysbiosis is yet to be fully elucidated. The aim of this review is to discuss the multiple ways in which the microbiota influences the overall genital inflammatory milieu and to explore the causes and consequences of this inflammatory response. While there is abundant evidence linking a diverse genital microbiota to elevated inflammation, understanding the risk factors and mechanisms through which it affects genital health is essential. A robust appreciation of these factors is important for identifying effective prevention and treatment strategies.
女性生殖道微生物群是一个复杂生态系统的一部分,受多种生理、遗传和行为因素的影响。它与女性的黏膜免疫密切相关,并在调节生殖器炎症方面起着关键作用。以乳酸杆菌丰度高和整体细菌多样性低为特征的阴道微生物群与较低的炎症水平相关。另一方面,更多样化的微生物群与高黏膜炎症水平、生殖道上皮屏障受损以及性传播感染和其他疾病的风险增加有关。一些细菌分类群,如 spp.、 spp.、 spp. 和 spp.,已知具有不良影响;然而,这种微生物失调的确切原因尚未完全阐明。本综述的目的是讨论微生物群影响整体生殖道炎症环境的多种方式,并探讨这种炎症反应的原因和后果。虽然有大量证据表明多样化的生殖道微生物群与炎症升高有关,但了解其影响生殖道健康的风险因素和机制至关重要。对这些因素的充分认识对于确定有效的预防和治疗策略非常重要。
