鉴于微生物组对人类健康的重要性,微生物组的稳定性及其对干扰的反应是关键问题。然而,我们对它们的了解还不够。早期的数据表明,在没有大的扰动的情况下,成年人的微生物生态系统是相对稳定的,人类社区的长期稳定性不是由惯性维持的,而是由动态系统内的恢复力的作用维持的。在短暂暴露于某些抗生素后,会立即出现显著的扰动,并且至少部分恢复分类组成。对抗生素的反应是个体化的,并受到先前使用相同抗生素的经验的影响。这些发现表明,人类微生物组具有弹性。除了用于揭示关键的潜在功能属性,微生物相互作用和本土微生物群中的关键物种外,对干扰的反应可能在预测未来的不稳定性和疾病以及管理人类微生物生态系统方面具有价值。
Given the importance of the microbiome for human health, the stability of the microbiome and its response to disturbance are crucial issues. Yet we have an insufficient understanding of them. Early data suggest that there is relative stability in the microbial ecosystem of adults in the absence of gross perturbation, and that long-term stability of human communities is not maintained by inertia, but by the action of restoring forces within a dynamic system. After brief exposures to some antibiotics, there is an immediate and substantial perturbation, and at least a partial recovery of taxonomic composition. Responses to antibiotics are individualized, and influenced by prior experience with the same antibiotic. These findings suggest that the human microbiome has properties of resilience. Besides serving to reveal critical underlying functional attributes, microbial interactions, and keystone species within the indigenous microbiota, responses to disturbance may have value in predicting future instability and disease, and in managing the human microbial ecosystem.
