Fermentation theory

Fermentation theory

The fermentation theory of disease is the (now obsolete) concept that many diseases, including the diseases which were "epidemic, endemic and contagious," owe their origin to the presence of a "morbific principle" in the system, acting in a manner analogous to, although not identical with, the process of fermentation.

It was rendered obsolete by the germ theory of disease, which led to the new science of bacteriology.
