ad·he·sins

(ad-hē'zins),

Microbial surface antigens that frequently exist in the form of filamentous projections (pili or fimbriae) and bind to specific receptors on epithelial cell membranes; usually classified according to their ability to induce agglutination of erythrocytes from various species, their differential attachment to epithelial cells of various origins, or their susceptibility to reversal of such binding activities in the presence of mannose.

[L. ad-haereo, pp. ad-haesum, to stick to, + -in]

adhesins

Proteins on the outer surfaces of micro-organisms that allow them to bind to cells they are attacking.

adhesins

substances which confer virulence on bacteria by enabling them to adhere to epithelial surfaces. See also pilus, fimbria.

AAF adhesins

aggregative adherence fimbriae; involved in the adherence of Escherichia coli to intestinal epithelial cells.
