MECHANISMS OF IMMUNOLOGIC PARALYSIS BY PNEUMOCOCCAL POLYSACCHARIDE. II. THE INFLUENCE OF NONSPECIFIC FACTORS ON THE IMMUNITY OF PARALYZED MICE TO PNEUMOCOCCAL INFECTION.

Large numbers of murine splenic and exudative cells failed to break paralysis. Paralyzed mice were made resistant to pneumococcal infection by injection of a suspension of normal splenic cells containing 0.5 µg of polysaccharide, but these results could not be regularly repeated.
