Latest paper from the lab - particularly glad that we managed to get this one out, after getting scooped several times over… more spectacular work from PhD students extraordinaire, Kailin and Rosa, in close collaboration with Marc Erhardt’s group.
The structure of the Vibrio alginolyticus flagellar filament suggests molecular mechanism for the rotation of sheathed flagella - Nature Communications
Most bacteria use a flagellum, to swim and disseminate in their environment, and it is essential for virulence. In Vibrio, the flagellum is surrounded by a sheath, a membrane-like shield that protects...
