Fimbriae: 1  Structure: Similar to pili, but shorter and more abundant on the cell surface. 2  Function: Adhesion of cells to surface and formation of pellicles (biofilms) containing thin sheets of cells on a liquid surface.
Attachment of bacteria to host surfaces is required for colonization during infection or to initiate formation of a biofilm. A fimbria is a short pilus that is used to attach the bacterium to a surface.
