A toxic substance produced by bacteria that helps the bacteria invade and damage body tissues.
From 'aggress' plus the biochemical suffix '-in' (used for proteins and enzymes). The -in suffix marks biological molecules and substances.
Bacteria literally fight our immune system with chemical weapons — aggressins are toxins that punch holes in cell membranes, explaining why infection is more than just bacterial numbers but biochemical warfare.
