Many disease-causing bacteria such as Pseudomonas aeruginosa crawl on surfaces through a walk-like motility known as "twitching". Nanometers-wide filaments called type IV pili are known to power ...

Researchers have characterized a mechanism that allows bacteria to direct their movement in response to the mechanical properties of the surfaces the microbes move on -- a finding that could help ...

Flagella are composed of over 20 unique proteins and represent a complex set of molecular machinery, working in unison to provide motility to many Gram-negative and positive species of bacteria, as ...
