Glycocalyx?????? Help me!

The glycocalyx most likely hides the surface proteins which are normally
recognized by antibodies preventing opsonization (coating) of the
bacterium with antibodies.  Many phagocytes can use the antibodies as
receptors to bind to and engulf the organism.  Alternatively, some folks
propose that the polysaccharides in the glycocalyx actually bind the
antibodies but since the material is shed it 1) prevents complement
fixation and 2) shed the antibodies with it.   Hope this extremely overly
simplified answer helps.
