Pseudomonas aeruginosa is a ubiquitous bacterium capable of twitching, swimming, and swarming motility. In this study, we present evidence that P. aeruginosa has two flagellar stators, conserved in all pseudomonads as well as some other gram-negative bacteria. Either stator is sufficient for swimming, but both are necessary for swarming motility under most of the conditions tested, suggesting that these two stators may have different roles in these two types of motility.
铜绿假单胞菌是一种无处不在的细菌，能够进行颤动、游动和群体运动。在本研究中，我们提供证据表明，铜绿假单胞菌有两个鞭毛定子，在所有假单胞菌以及其他一些革兰氏阴性细菌中都保守存在。任何一个定子都足以支持游动，但在大多数测试条件下，两个定子对于群体运动都是必需的，这表明这两个定子在这两种运动类型中可能具有不同的作用。
