Abstract
Hydrosoluble extracts of mycobacteria suitable as immunological adjuvants are prepared. These extracts have a molecular weight between 3,500 and 30,000 and adjuvant, non-arthrogen properties. The delipidated bacterial residues of mycobacteria are subjected to a mild extraction, then the so-obtained substance is isolated and purified by physicochemical methods, or the delipidated bacterial residues of mycobacteria are treated by means of pyridine, optionally in the presence of acetic anhydride, then the obtained products are treated with ethanol or water, and the hydrosoluble substances are isolated and purified by physicochemical methods.
