Bacterial swarming is an example of dynamic self-assembly in microbiology in which the collective interaction of a population of bacterial cells leads to emergent behavior. Swarming occurs when cells interact with surfaces, reprogram their physiology and behavior, and adapt to changes in their environment by coordinating their growth and motility with other cells in the colony. This review summarizes the salient biological and biophysical features of this system and describes our current understanding of swarming motility. We have organized this review into four sections: 1) The biophysics and mechanisms of bacterial motility in fluids and its relevance to swarming. 2) The role of cell/molecule, cell/surface, and cell/cell interactions during swarming. 3) The changes in physiology and behavior that accompany swarming motility. 4) A concluding discussion of several interesting, unanswered questions that is particularly relevant to soft matter scientists.
细菌群体运动是微生物学中动态自组装的一个例子，其中一群细菌细胞的集体相互作用导致了涌现行为。当细胞与表面相互作用、重新编程其生理和行为，并通过与菌落中的其他细胞协调生长和运动来适应环境变化时，就会发生群体运动。这篇综述总结了该系统的主要生物学和生物物理特征，并描述了我们目前对群体运动性的理解。我们将这篇综述分为四个部分：1）细菌在流体中的运动生物物理学和机制及其与群体运动的相关性。2）群体运动过程中细胞/分子、细胞/表面和细胞/细胞相互作用的作用。3）伴随群体运动性的生理和行为变化。4）对几个有趣的、未解决的问题的总结讨论，这些问题对软物质科学家尤为相关。
