bacterium

Definition

A microscopic single-celled organism that lacks a nucleus but makes up for it with an impressive ability to cause trouble in your gut. These tiny troublemakers have cell walls for protection but skip the fancy organelles that more sophisticated cells enjoy. Think of them as the studio apartments of the biological world—compact, efficient, and occasionally responsible for food poisoning.

Example Usage

The lab tech identified the bacterium responsible for the outbreak as a particularly aggressive strain of E. coli.

A fancy medical term for the tests and procedures doctors use to figure out what's actually wrong with you, ranging from simple blood work to expensive machines that go "ping."
