Process for obtaining agents having mitogenic and/or adjuvant properties from Nocardia cells and compositions containing such agents

摘要

The invention relates to a process for obtaining agents having mitogenic and/or adjuvant properties, from Nocardia cells. According to this process Nocardia whole cells are subjected to a rupturing treatment of their walls within an aqueous medium, particularly distilled water. After the separation of the non-ruptured cells and of the wall fragments of the ruptured cells, mitogenic agents are extracted from the remaining aqueous phase. The fractions obtained are useful as laboratory reagents and for the production of medicamentous compositions in which they are associated with a pharmaceutical vehicle.
