Dissipative shocks behind bacteria gliding.
Gliding is a means of locomotion on rigid substrates used by a number of bacteria, including myxobacteria and cyanobacteria. One of the hypotheses advanced to explain this motility mechanism hinges on the role played by the slime filaments continuously extruded from gliding bacteria. This paper solves, in full, a non-linear mechanical theory that treats as dissipative shocks both the point wher...
متن کاملGliding Motility: The Molecules behind the Motion
In apicomplexan parasites, gliding motility and host cell invasion are driven by an actomyosin-based system. Recent studies have characterized several components of the gliding motility apparatus and have provided new insight into the molecular architecture of this locomotory system.
متن کاملFlower-shaped Micromotors Driven by Gliding Bacteria
A flower-shaped micromotor driven by gliding bacteria named Mycoplasma mobile (M. mobile) has been developed by using two-photon microfabrication. This micromotor is autonomously rotated by the collisions of M. mobiles gliding randomly on a substrate. The flower-shaped rotor is derived from the unique motility of M. mobile. We examined the motility characteristics of M. mobile using walls with ...
متن کاملBacterial motility: Secretory secrets of gliding bacteria
Many bacteria glide over surfaces without the aid of flagella. Gliding is still somewhat mysterious, but recent studies show that it involves specialized secretory systems that assemble membrane-associated filaments, and the recognition of extracellular components that trigger movement via transmembrane transducers.
متن کاملAntibacterial activity of aquatic gliding bacteria
The study aimed to screen and isolate strains of freshwater aquatic gliding bacteria, and to investigate their antibacterial activity against seven common pathogenic bacteria. Submerged specimens were collected and isolated for aquatic gliding bacteria using four different isolation media (DW, MA, SAP2, and Vy/2). Gliding bacteria identification was performed by 16S rRNA gene sequencing and phy...
