endotoxin

EN-doh-tok-sin

Definition

A toxic substance present inside a bacterial cell that is released when the bacterium dies or disintegrates, potentially causing inflammation or illness.

Etymology

The word is derived from the Greek 'endon' meaning 'within' and 'toxikon' meaning 'poison'. It entered scientific terminology to describe toxins that are bound to the cell wall of bacteria rather than being secreted into the surrounding environment.
