Adhesins Gram-positive bacteria

First, bacterial adhesion (usually gram-positive cocci and filamentous bacteria) occurs primarily through a Ca + complex formation between carboxyl (COO ) and phosphate (HPOs ) groups of bacterial surface and acquired pelhcle, although van der Waals forces and repulsive electrostatic forces are also present. Some specific bacterial surface proteins also serve as adhesins for specific receptors on acquired peUicle. Pellicle-integrated immunoglobulins also bind bacteria specifically.
