I think that may be due to prolonged exposure. Because our bodies attempt to attain homeostasis constantly, our bugs will naturally get rid of a small introduction to something foreign. But if it's a constant input of something foreign it attempts to reach an equilibrium without having to constantly rid itself of foreign bugs.
