Alternatively, Tanon’s reasoning implies the emergence of a more holistic and environmentally oriented see of microbiology before 1920. The principle of reservoir identified the equations “microbe + host = Demise in the host” or “microbe + vector + host = Demise in the host” was much more advanced and involved various other ecological components.
