细菌群集是微生物学中动态自组装的一个例子，其中细菌细胞群体的集体相互作用导致紧急行为。当细胞与表面相互作用，重新编程它们的生理和行为，并通过与殖民地中的其他细胞协调它们的生长和运动来适应环境的变化时，就会发生群集。本文综述了该系统的生物学和生物物理学特征，并介绍了我们目前对群集运动的理解。我们将这篇综述分为四个部分：1）流体中细菌运动的生物物理学和机制及其与群集的相关性。2)细胞/分子、细胞/表面和细胞/细胞相互作用在群集过程中的作用。3)蜂群运动伴随的生理和行为变化。4)最后讨论几个有趣的，未回答的问题，特别是有关软物质科学家。
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.
