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 ...
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.
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.
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...
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.
driven swarming, these include type IV pilus-dependent twitching and focal adhesion complex supported gliding (Kearns, 2010). Further, swarming-based collective motility might be facilitated by additional secreted pro-teins, promoting wandering colony formation during sur-face colonization (Kobayashi et al., 2016). Contrary to
4 de abr. de 2017 · Sliding, darting and gliding are all relevant to the discussion of motility in the Staphylococci. To be consistent with the historical definitions of motility, spreading and darting are forms of passive motility, but comets resemble gliding and could, therefore, be considered active.
