Bacteria use a range of sensory systems to mount appropriate responses to their environment. A new study now shows that the opportunistic pathogen Pseudomonas aeruginosa uses its type IV pili (which are composed of pilin subunits and are mainly used for surface motility) to sense contact with a...

Some bacteria have a single, tail-like flagellum or a small cluster offlagella, which rotate in coordinated fashion, much like the propeller on a boat engine, to push the organism forward. The hook: Many bacteria also use appendages called pilli to move along a surface. What is true pili?
Function of pili in bacterial colonization The role of pili in host cell adherence and tissue tropism has been well established from studies of Gram-negative bacteria, which contain distinct types of pili, namely type I pili, Pap pili, type IV pili and curli pili 16, 34, 35, 36. Gram-po...
sortase,are crosslinked,ultimately resulting in polymers covalently attached to the cell wall.Pili mainly take part in bacterial adhesion to and invasion and colonization of host tissues and cells.This paper reviews the structure,molecular configuration,and function of pili in Gram-positive bacteria.关键...
The scope of this Review is to summarize what is known about the structure, assembly and function of pili in Gram-positive bacteria and, in particular, in the three important human streptococcal pathogens, S. pyogenes, S. agalactiae and S. pneumoniae. Pili in Gram-positive bacteria In Gram-...
