Abstract
The invention pertains to a mitrogenic agent and to a process for obtaining same. It comprises the steps of cultivating Nocardiae cells, collecting them, subjecting them to a treatment for rupturing the integrity of their walls, such as by lysis, discarding the solid residue and collecting the aqueous fraction, causing the peptidoglycane fragments contained in this aqueous fraction to be separated therefrom and recovering the remaining fraction containing the mitogenic agent.
