An exotoxin can cause damage to the host by destroying cells or disrupting normal cellular metabolism. They are highly potent and can cause major damage to the host.

Exotoxin, a poisonous substance secreted by certain bacteria. In their purest form they are the most potent poisons known and are the active agents in diphtheria, tetanus, and botulism.

Jun 19, 2025 · Endotoxins form part of bacterial cell walls, while exotoxins are proteins that bacteria secrete or release when they die. Endotoxins are lipopolysaccharides found in the outer membranes …

Exotoxins, typically secreted by bacteria into their surrounding environment, differ notably from endotoxins, which are integral components of bacterial cell walls released upon cell lysis or death. …

These toxins can be divided into two groups: exotoxins, which are protein- or peptide-based toxic substances secreted by bacteria, and endotoxins, which are usually found within the cell wall and …

Unlike endotoxin, which is an integral part of the Gram-negative outer membrane, exotoxins are secreted proteins that can be produced by Gram-positive and Gram-negative bacteria.

Exotoxins are produced by several Gram-positive and Gram-negative bacteria and are among the most toxic substances known. Many exotoxins have an A-B subunit structure; B, or binding subunit, is …
