微生物组在人类健康中发挥着重要作用。微生物群的变化可以赋予病原菌抵抗力或促进病原菌感染。抗生素对微生物群有着深远的影响,改变了肠道的营养状况,并可能导致致病菌群的扩张。病原菌利用微生物来源的碳和氮源作为营养物质和调节信号来促进其自身的生长和毒力。通过引发炎症,这些细菌改变了肠道环境,并使用独特的呼吸和金属获取系统来驱动它们的扩张。解开微生物群,宿主和病原菌之间的相互作用将产生操纵微生物群对抗传染病的策略。
The microbiome has an important role in human health. Changes in the microbiota can confer resistance to or promote infection by pathogenic bacteria. Antibiotics have a profound impact on the microbiota that alters the nutritional landscape of the gut and can lead to the expansion of pathogenic populations. Pathogenic bacteria exploit microbiota-derived sources of carbon and nitrogen as nutrients and regulatory signals to promote their own growth and virulence. By eliciting inflammation, these bacteria alter the intestinal environment and use unique systems for respiration and metal acquisition to drive their expansion. Unravelling the interactions between the microbiota, the host and pathogenic bacteria will produce strategies for manipulating the microbiota against infectious diseases.
