Bacteria are constantly moving by help of motility organs called flagella or pili to colonize new niches. Also, bacteria can exchange information, like “speaking to each other”, and thus acquire new ...

Flagellated bacteria are propelled by the rotation of helical flagellar filaments, each with a flagellar motor at its base. Taking Escherichia coli (E. coli) as an example, each cell has 3–7 flagella ...

Millions of people worldwide are periodically or chronically affected by gut-related conditions, such as irritable bowel ...

Type IV pili are retractile, filamentous appendages that drive twitching motility, facilitating the early stages of biofilm formation on biotic and abiotic surfaces. Through cycles of pilus extension, ...

By combining experimental evolution in soft agar, inducible control of run duration, visualization of flagella, and theoretical modeling, the authors demonstrate that the optimal mean run duration for ...

Structural patterns can be created due to the chasing interactions between two bacterial species. In a new model, scientists describe how interactions on the individual level can result in a global ...

In the classic “run-and-tumble” movement pattern, bacteria swim forward (“run”) in one direction and then stop to rotate and reorient themselves in a new direction (“tumble”). During experiments where ...

“A very diverse set of gut bacteria can ‘swim’ through the layer of mucus that lines the intestines using specialized thread-like structures called flagella, the assembly and function of which ...
