(Äd-hÄ'zhÉn) 1  The force of attraction that causes two different substances to join. Adhesion causes water to spread out over glass. 2  A fibrous band of abnormal tissue that binds together tissues that are normally separate. Adhesions form during the healing of some wounds, usually as a result of inflammation.
The typical structure of a bacterial adhesion is that of a fimbria or pili. The bacterial adhesion consists primarily of an intramembranous structural protein which provides a scaffold upon which several extracellular adhesins may be attached.A large number of bacterial adhesins with individual receptor specificities have been identified.â Many bacterial pathogens are able to express an array of different adhesins. Expression of these adhesins at different phases during infection play the most important role in adhesion based virulence.
