Structures used by bacteria for attachment
Fimbriae (sometimes called "attachment pili") are protein tubes that extend out from the outer membrane in many members of the Pseudomonadota. They are generally short in length and present in high numbers about the entire bacterial cell surface. Fimbriae usually function to facilitate the attachment of a bacterium to a surface (e.g. to form a biofilm) or to other cells (e.g. animal cells during pathogenesis). A few organisms (e.g. Myxococcus) use fimbriae for motility t… WebFor instance, flagella are whip-like structures that act as rotary motors to help bacteria move. Fimbriae are numerous, hair-like structures that are used for attachment to host cells and other surfaces. Bacteria may also have rod-like structures known as pili, which come in different varieties.
