MeSH Heading: Fimbriae, Bacterial
Tree Number(s): A11.284.180.285; A20.843
Unique ID: D010861
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D010861
Scope Note: Thin, hairlike appendages, 1 to 20 microns in length and often occurring in large numbers, present on the cells of gram-negative bacteria, particularly Enterobacteriaceae and Neisseria. Unlike flagella, they do not possess motility, but being protein (pilin) in nature, they possess antigenic and hemagglutinating properties. They are of medical importance because some fimbriae mediate the attachment of bacteria to cells via adhesins (ADHESINS, BACTERIAL). Bacterial fimbriae refer to common pili, to be distinguished from the preferred use of pili, which is confined to sex pili (PILI, SEX).
