Intro

When we study Medicine-related Microbiology or Infectious Diseases, some words keep popping up:

infection,

pathogen,

colonization.

And many others related.

This article:

• gives simple definitions of those and many other common words and expressions in Medical Microbiology and, at the same time,
• provides an overview of how microorganisms interact with us.

Terms specifically related to the immune system’s defence mechanisms against microorganisms are not covered.
