microorganism

Noun

 * 1)  An organism that is too small to be seen by the unaided eye; especially, a single-celled organism, such as a bacterium.

Usage notes

 * Whether viruses are alive, and thus whether they are microorganisms (microbes), is a matter of variable ontology; the semantic field of the word is often taken to include viruses in casual or broad terms, but not always in precise terms.
 * GPO manual recommends using a hyphen to avoid doubling a vowel except after short prefixes. However, microorganism is several times more common than micro-organism in print and most dictionaries only have the spelling microorganism.
