Abstract

The Germ-Terrain duality theory of disease states that the aetiology of certain diseases/diseased states is better explained as a complex interplay between germs and the inherent anatomical/ physiological integrity of the body cells [1]. It argues that the aetiology of certain diseases is not fully explained merely by the presence of germs (Germ Theory) or by a mere loss of cellular integrity (Terrain Theory) [2-6]. As a result, the prevention and treatment of such diseases should focus not just on fighting germs but on maintaining/ restoring the anatomical/physiological cellular integrity [7-11]. The Germ-Terrain duality theory is a harmonization of the current Germ Theory (popularized by Louis Pasteur) and the hitherto discarded Terrain Theory (popularized by Pierre Bechamp) [11-14].
