人类肠道是数万亿微生物的家园,它们与人类宿主形成共生关系。在健康期间,肠道微生物群为宿主提供了许多益处,并且通常对新物种的定植具有抵抗力;然而,这种复杂群落的破坏可能导致病原体入侵,炎症和疾病。恢复和维持健康的肠道微生物群组成需要有效的疗法来减少和防止有害细菌(病原体)的定植,同时促进有益细菌(益生菌)的生长。在这里,我们回顾了宿主在健康和疾病期间调节肠道群落组成的机制,并讨论了抗生素和益生菌治疗在破坏后恢复健康肠道群落的前景。
The human gut is home to trillions of microbes that form a symbiotic relationship with the human host. During health, the intestinal microbiota provides many benefits to the host and is generally resistant to colonization by new species; however, disruption of this complex community can lead to pathogen invasion, inflammation, and disease. Restoration and maintenance of a healthy gut microbiota composition requires effective therapies to reduce and prevent colonization of harmful bacteria (pathogens) while simultaneously promoting growth of beneficial bacteria (probiotics). Here we review the mechanisms by which the host modulates the gut community composition during health and disease, and discuss prospects for antibiotic and probiotic therapy for restoration of a healthy intestinal community following disruption.
