text: Bacterial surface structures may act as (1) permeability barriers that allow selective passage of nutrients and exclusion of harmful substances (e.g. antimicrobial agents); (3) adhesins used to attach or adhere to specific surfaces or tissues; (3) enzymes to mediate specific reactions on the cell surface important in the survival of the organism; (4) protective structures against phagocytic engulfment or killing; (5) antigenic disguises to bypass activation of host immune defenses; (6) endotoxins, generally cell wall components, that cause an inflammatory response in the host; (7) "sensing proteins" that can respond to temperature, osmolarity, salinity, light, oxygen, nutrients, etc., resulting in a molecular signal to the genome of the cell that will cause expression of some determinant of virulence (e.g. an exotoxin).
