BACTERIAL AND SYNTHETIC POLYSACCHARIDES FOR THE ENHANCEMENT OF GENERAL IMMUNITY

摘要

The present invention relates to the effects of bacterial polysaccharides on cell mediated immunity in animals. Polysaccharides of the present invention comprise the outerpolysaccharides (OPS) located on bacterial cell membranes and other polysaccharides (e.g. "Poly B") either secreted or contained within the periplasmic space. These polysaccharides have been found to enhance the general or cell mediated immunity of animals to various diseases. The invention provides for the use of such polysaccharides in preventing and treating various infections as well as in treating carcinomas. The invention also provides for synthetic polysaccharides having the same immuno-modulating effect as the bacterial polysaccharides.
