In this issue of Cell Host and Microbe, Robinson et al. (2021) make elegant use of experimental evolution to demonstrate that increased motility promotes migration toward and colonization of zebrafish larvae by a commensal bacterium. Stimulation of motility depends on bacterial second messenger and on signals released by resident host microbiota.

追赶宿主：刺激细菌运动促进定植

在本期Cell Host and Microbe 中，Robinson 等人。(2021) 巧妙地利用实验进化来证明增加的运动性促进了共生细菌向斑马鱼幼虫迁移和定植。运动的刺激取决于细菌的第二信使和常驻宿主微生物群释放的信号。
