El fenómeno más conocido de éstos es el de “swarming”, observado en Proteus spp., en el cual las bacterias sufren una transfiguración importante convirtiéndose en formas filamentosas hiperflageladas. Sin embargo, otros tipos de desplazamiento que se presentan son “swim-ming”, “twiching”, “gliding”, “sliding” y ...
9 de ago. de 2010 · This landmark study characterizes the motile behaviour of over 500 bacterial isolates and defines the main types of bacterial movement: swimming, swarming, twitching, gliding and sliding.
Twitching is surface movement powered by the extension and retraction of pili. Gliding is active surface movement that does not require flagella or pili and involves focal adhesion complexes. Sliding is passive surface translocation powered by growth and facilitated by a surfactant.
21 de sept. de 2021 · On surfaces, bacteria swarm collectively in a thin layer of fluid powered by the rotation of rigid helical filaments, they twitch by assembling and disassembling type IV pili, they glide by...
9 de ago. de 2010 · tinguish swarming from behaviours such as swimming, twitching, gliding and sliding, which can also occur within or on top of solid surfaces3 (FIG. 1). Swimming motility is a mode of...
RESUMEN. Algunas bacterias exhiben diversos tipos de desplazamiento sobre los medios de cultivo sólidos, lo que se pone en evidencia por la presencia de velos o películas de crecimiento en el entorno de las colonias.
Swarming bacteria move as groups of cells using their flagella through a thin liquid layer on semisolid surfaces. In fact, the cells of many swarming species elongate and/or hyperflagellate in some fashion. (Some have argued that flagellar-dependent surface motile bacteria that do not differentiate their cells are not truly ‘swarming’.)
