Differences Between Endotoxins and Exotoxins

Conclusion – Difference Between Endotoxins And Exotoxins

The endotoxin vs exotoxin is given below:

Feature	Endotoxins	Exotoxins
Definition	It is a bacterial toxin and a lipopolysaccharide.	It is a soluble protein that is secreted to the outside of the bacterial cell.
Type of Molecule	Lipopolysaccharide	Protein
Produced By	Gram-negative bacteria	Both Gram-negative and positive bacteria.
Enzymatic activity	Does not act as enzymes.	Act as enzymes.
Toxicity	Less Toxic	Highly Toxic.
Mode of conversion	Cannot be converted to toxoid.	Can be converted to toxoid.
Fatal	It doesn’t prove to be fatal.	It is often fatal in larger quantities.
Diseases caused	Urinary Tract Infection Ischemic Heart Disease Meningococcal Meningitis	Scarlet fever Botulism Scalded skin syndrome
Location	Within the outer membrane of the bacterium.	In the extracellular fluid.
Antigenicity	Less antigenic	Highly antigenic
Example of toxin producing bacteria	Salmonella typhi (Typhoid), Vibrio cholerae (Cholera).	Clostridium tetani (Tetanus), Clostridium botulinum (Botox),

Difference Between Endotoxins and Exotoxins

The major difference between endotoxin and exotoxin lies in how bacteria produce these toxins. Endotoxins are produced by Gram-negative bacteria and exotoxins are produced by bacteria that release toxins into the surroundings. The toxins are toxic substances, including proteins, small molecules, and peptides, which cause disease upon contact with or absorption from body tissues.

The difference between endotoxin and exotoxin lies in their origins and how they affect the body. In this article, we will cover the difference between endotoxin and exotoxin in tabular form.
