ADHERENCE Once the pathogen has gained access to the body, it usually must have some means of attaching  itself to the host’s tissues. This attachment is called adherence and is a necessary step in  pathogenicity. This attachment is accomplished by means of surface molecules on the pathogen  called adhesins or ligands that bind to complementary receptors on the cells of certain host  tissues. Adhesins may be located on the glycocalyx or other surface structures of the microbe  such as fimbriae. Adhesins are most frequently glycoproteins or lipoproteins. Receptors are  usually sugars which are associated with the plasma membrane. Not everyone's cells have the  same receptors and not all cells belonging to the same body have the same receptors. If the  adhesins or the receptors can be altered, this can be a way of preventing infection.
