Preferred Label : fimbriae, bacterial;
MeSH definition : 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).;
MeSH synonym : fimbria, bacterial; bacterial fimbriae; pili, common; common fimbriae; fimbriae, common; pilus, common; common fimbria; common pilus; fimbria, common; bacterial fimbria; common pili;
