Twitching motility pseudomonas aeruginosa

WebApr 26, 2015 · Abstract Twitching motility is a flagella-independent form of bacterial translocation over moist surfaces. It occurs by the extension, tethering, and then retraction of polar type IV pili, which operate in a manner similar to a grappling hook.
