[主题词] Adhesins,Bacterial
[英文释义] Cell-surface components or appendages of bacteria that facilitate adhesion (BACTERIAL ADHESION) to other cells or to inanimate surfaces. Most fimbriae (FIMBRIAE,BACTERIAL) of gram-negative bacteria function as adhesins,but in many cases it is a minor subunit protein at the tip of the fimbriae that is the actual adhesin. In gram-positive bacteria,a protein or polysaccharide surface layer serves as the specific adhesin.
