Béchamp strongly contested this view offering up a competing idea known as the pleomorphic theory of disease. This theory says that all life is based on forms that a certain class of organisms take during stages of their life-cycles and that germs are attracted to the environment of diseased tissue rather than being the cause of it.[6] Proponents of this idea insist microbes that live in an organism go through the same stages of their development. According to Günther Enderlein they are as follows: Colloid – microbe (primitive phase), bacteria (middle phase), and fungus (end phase).[7]
