许多微生物群落,包括那些参与慢性人类感染的微生物群落,都是在微米尺度上形成的。在这篇综述中,我们总结了最近的工作,这些工作已经定义了感染中微生物的空间排列,并开始展示空间模式的变化如何与疾病相关。显微镜技术的进步使我们对人类样本中微生物的微米级微生物学有了更深入的了解。然后,这些发现可以作为研究空间模式在临床前模型中的作用的基准,这些模型提供了实验的多功能性,以研究血管造影和发病机制之间的相互作用。使用临床前模型的实验已经开始显示空间模式如何影响细胞之间的相互作用,它们的共存能力,它们的毒力和它们对治疗的耐受性。未来的工作,以研究感染和微生物的功能性细菌学的作用,将进一步完善我们的理解的空间格局,病原体毒力和疾病的结果的相互作用。
Many microbial communities, including those involved in chronic human infections, are patterned at the micron scale. In this Review, we summarize recent work that has defined the spatial arrangement of microorganisms in infection and begun to demonstrate how changes in spatial patterning correlate with disease. Advances in microscopy have refined our understanding of microbial micron-scale biogeography in samples from humans. These findings then serve as a benchmark for studying the role of spatial patterning in preclinical models, which provide experimental versatility to investigate the interplay between biogeography and pathogenesis. Experimentation using preclinical models has begun to show how spatial patterning influences the interactions between cells, their ability to coexist, their virulence and their recalcitrance to treatment. Future work to study the role of biogeography in infection and the functional biogeography of microorganisms will further refine our understanding of the interplay of spatial patterning, pathogen virulence and disease outcomes.
