Microbiology: Bright Insight into Bacterial Gliding, Science
Excerpts: On page 853 of this issue, Mignot et al. provide evidence for a novel mode of bacterial locomotion (1). According to their model, a bacterium adheres to a solid surface at regular intervals along its cell body. Coordinated force is uniformly applied at focal adhesion complexes and the cell moves relative to these foci. Quantitative measurements and mathematical modeling predict that the zones of adhesion are organized on an internal helical track and that relative movement of the track could power a spiraling, corkscrew-like motion over a surface (see the figure).
