游泳运动被认为是细菌物种的一种有益特性，因为它可以在流体环境中运动，并增加对宿主组织的入侵。然而，不会游泳的细菌也在流体栖息地中大量繁殖，但它们如何有效地传播和殖民遥远的生态位仍不清楚。我们表明，非运动性葡萄球菌可以通过搭便车游动细菌获得运动性，从而导致速度增加的延伸和定向运动。在金黄色葡萄球菌和铜绿假单胞菌、表皮葡萄球菌和铜绿假单胞菌、金黄色葡萄球菌和大肠杆菌之间观察到这种相互作用，表明搭便车是非运动葡萄球菌的一般易位机制。通过利用游动细菌的运动性，观察到葡萄球菌可以在没有游动载体的情况下定植新的生态位。这项工作强调了考虑多微生物群落中物种之间相互作用的重要性，细菌可以利用彼此作为资源。
Swimming motility is considered a beneficial trait among bacterial species as it enables movement across fluid environments and augments invasion of tissues within the host. However, non-swimming bacteria also flourish in fluid habitats, but how they effectively spread and colonize distant ecological niches remains unclear. We show that non-motile staphylococci can gain motility by hitchhiking on swimming bacteria, leading to extended and directed motion with increased velocity. This phoretic interaction was observed betweenStaphylococcus aureusandPseudomonas aeruginosa, Staphylococcus epidermidis and P. aeruginosa,as well asS. aureusandEscherichia coli, suggesting hitchhiking as a general translocation mechanism for non-motile staphylococcal species. By leveraging the motility of swimming bacteria, it was observed that staphylococci can colonize new niches that are less available in the absence of swimming carriers. This work highlights the importance of considering interactions between species within polymicrobial communities, in which bacteria can utilize each other as resources.
