Fimbriae are hair-like appendages present on the surface of many bacteria, primarily involved in adhesion to surfaces and other cells. They play a significant role in bacterial colonization and virulence.
5 Must Know Facts For Your Next Test
Fimbriae differ from pili; fimbriae are shorter and more numerous.
They are crucial for bacterial adherence to host tissues, enhancing infection potential.
Fimbriae can be involved in biofilm formation, contributing to microbial growth and persistence.
Pathogenic bacteria use fimbriae to attach to mucosal surfaces during infections of the gastrointestinal tract.
Some bacteria have specialized fimbriae that recognize specific host receptors, increasing their virulence.
