我们描述了大肠杆菌和鼠伤寒沙门氏菌中的一种新的行为反应，在这种反应中，细菌分化为丝状、多核、多鞭毛的细胞，这些细胞通过协同的群集运动在固体培养基表面移动。分化为群集细胞的诱导因素是琼脂的浓度和成分。对各种突变体行为的检测表明，用于游动运动的鞭毛装置和趋化性系统对于群集运动是必不可少的。
We describe a new behavioral response in Escherichia coli and Salmonella typhimurium in which the bacteria differentiate into filamentous, multinucleate, hyper-flagellate cells that navigate the surface of solid media by means of coordinated swarming motility. The cue for differentiation into swarmer cells is provided by the concentration and composition of the agar. Examination of the behavior of various mutants shows that the flagellar apparatus used for swimming motility and the chemotaxis system are indispensable for swarming motility.
