Was the disease caused by a micro-organism or the result of previous cellular degeneration?

Was the disease caused by a micro-organism or the result of previous cellular degeneration?
Was the breakdown in the immune system caused by poor living and dietary habits? Is the dysfunctional internal environment caused by poor health a perfect breeding ground for pathogenic organisms? Do micro-organisms mutate from one form into another, depending on the health of the individual? Can this path of mutation be reversed?

Recent advances in microscope technology have opened new vistas of understanding.
Dark field and phase contrast microscopy used in the study of live blood has revealed new dimensions of cellular and intracellular activity. The many years of research by Gaston Naessens has resulted in the discovery of an ultramicroscopic, sub-cellular, living and reproducing microscopic form called a somatid.

These forms were found to exist in the intra and inter cellular fluids of all living plants and animals.
Somatids were cultured outside the hosts and went through 16 different changes, each relating to a different level of health for the host organism. As the health improved, the pathogenic cycle reversed direction. When health levels declined the organisms changed from symbiotic to pathological.
