Gliding motility of Mycoplasma pulmonis.
The gliding movements of freshly isolated Mycoplasma pulmonis cells were observed and measured. The motile cells had a characteristic appearance, an average speed of 0.4 to 0.7 micron/s, and a maximum speed of 1 micron/s.
متن کاملIsolation of Herpetosiphon giganteus and Ultrastructure Analysis by Electron Microscopy
Herpetosiphon giganteus is a filamentous gliding bacterium. Gliding motility is the movement of the cells over surfaces without the aid of flagella. The mechanism responsible for bacterial gliding motility has not been known and there are only a few data on Herpetosiphon giganteus. The aim of this study was to observe the ultrastructure and negative staining of isolated strains of Herpetosiphon...
متن کاملPolymer confinement and bacterial gliding motility.
Cyanobacteria and myxobacteria use slime secretion for gliding motility over surfaces. The slime is produced by the nozzle-like pores located on the bacteria surface. To understand the mechanism of gliding motion and its relation to slime polymerization, we have performed molecular dynamics simulations of a molecular nozzle with growing inside polymer chains. These simulations show that the com...
متن کاملGliding motility and Por secretion system genes are widespread among members of the phylum bacteroidetes.
The phylum Bacteroidetes is large and diverse, with rapid gliding motility and the ability to digest macromolecules associated with many genera and species. Recently, a novel protein secretion system, the Por secretion system (PorSS), was identified in two members of the phylum, the gliding bacterium Flavobacterium johnsoniae and the nonmotile oral pathogen Porphyromonas gingivalis. The compone...
متن کاملThe junctional pore complex, a prokaryotic secretion organelle, is the molecular motor underlying gliding motility in cyanobacteria
BACKGROUND Whereas most bacteria move by means of flagella, some prokaryotes move by gliding. In cyanobacteria, gliding motility is a slow uniform motion which is invariably accompanied by a continuous secretion of slime. On the basis of these characteristics, a model has been proposed in which the gliding motility of cyanobacteria depends on the steady secretion of slime using specific pores, ...
