Pilus - Wikipedia
网页A pilus (Latin for 'hair'; pl.: pili) is a hair-like appendage found on the surface of many bacteria and archaea. [1] The terms pilus and fimbria (Latin for 'fringe'; plural: fimbriae) can be used interchangeably, although some researchers reserve the term pilus for the appendage required for bacterial conjugation.

Pilus - an overview | ScienceDirect Topics
网页Pili, also known as fimbriae, are proteinaceous, filamentous polymeric organelles expressed on the surface of bacteria. They range from a few fractions of a micrometer to > 20 μm in length and vary from < 2 to 11 nm in diameter. Their functions include mediation of cell-to-cell interactions, motility, and DNA uptake.
Bacterial Pili (Fimbriae): Types, Functions • Microbe Online
网页Bacteria use adherence fimbriae (pili) to overcome the body’s defense mechanism and cause disease. Pili are small hairs that enable some pathogens to attach and adhere easily to cell surfaces, particularly mucous membranes. Bacteria possessing pili include Neisseria gonorrhoeae and some strains of Escherichia coli, Salmonella, and Shigella ...

The Biosynthesis and Structures of Bacterial Pili
网页2019年6月19日 · To interact with the external environments, bacteria often display long proteinaceous appendages on their cell surface, called pili or fimbriae. These non-flagellar thread-like structures are polymers composed of covalently or non-covalently interacting repeated pilin subunits.
