What do Micro-Organisms have in them?
Bacteria, like all micro-organisms are microscopic, but are at least 10 x the size of a virus. Bacteria can duplicate itself, but most of the bacteria in our bodies are completely unharmful. The Harmful sort is called Pathogenic Bacteria, and enters the body through water or food. They then attach themselves to cells and reproduce using the human body as nutrition.
