WebHere we show that oxylipins derived from this activity inhibit flagellum-driven motility and upregulate type IV pilus-dependent twitching motility of P. aeruginosa. Twitching motility is a form of crawling bacterial motility used to move over surfaces. Twitching is mediated by the activity of hair-like filaments called type IV pili which extend from the cell's exterior, bind to surrounding solid substrates and retract, pulling the cell forwards in a manner similar to the action of a … See more Pilus structure The type IV pilus complex consists of both the pilus itself and the machinery required for its construction and motor activity. The pilus filament is largely composed of the PilA protein, with … See more Pathogenesis Both presence of type IV pili and active pilar movement appear to be important contributors to the pathogenicity of several species. In P. aeruginosa, loss of pilus retraction results in a reduction of bacterial virulence in … See more Type IV pili and related structures can be found across almost all phyla of Bacteria and Archaea, however definitive twitching motility has been shown in a more limited range of … See more • Gliding motility • Pilus • Swarming motility See more

WebNov 25, 2024 · The motility mechanism of certain prokaryotes has long been a mystery, since their motion, known as gliding, involves no external appendages. ... Inspection of a swarm of myxobacteria, such as Myxococcus xanthus, reveals 2 types of motility: social (S)-motility or “twitching” involving type IV pili, ... WebApr 12, 2024 · Twitching motility: This type of motility involves the extension and retraction of pili, which are hair-like structures that extend from the surface of the bacterial cell. The pili attach to surfaces and pull the bacterial cell forward. Bacteria that use twitching motility include Pseudomonas aeruginosa and Neisseria gonorrhoeae.
