Document Summary
What we learn from macro-organisms can be applied to the microorgnisms in infectious diseases.

Animal ecologists were talking about niches defined rigorously by g. evelyn. Hutchinson: fundamental niche food, temperature, other environmental variables, competition constrains species to a subset of their fundamental niche, called the realized niche.
