Definition:
-
(bacteria) microorganisms (living creatures so small it takes a microscope to see them) that can both cause disease and be beneficial.
(Bacteria are different and larger than viruses.)editor's notes: A single bacteria is called a bacterium and consists of a single cell that reproduces by splitting. (This is unlike a virus that uses cells in the body to reproduce.)
Bacteria are found virtually everywhere. For example, there are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a milliliter of fresh water. Many bacteria reside on our skin and in our bodies. For example, bacteria in the stomach help animals digest food.
