Exotoxins are toxic substances secreted by bacteria and released outside the cell. Whereas Endotoxins are bacterial toxins consisting of lipids that are located within a cell. Following are the few differences between exotoxin and endotoxin. Characteristics Exotoxins Endotoxins Source Living gram positive and gram negative bacteria Lysed gram negative bacteria Location Released from the cell The main difference between endotoxin, enterotoxin, and exotoxin is that endotoxin is a lipopolysaccharide found in the outer membrane of the Gram-negative bacteria. But, exotoxin is a protein mainly secreted by Gram-positive bacteria. Mean while, enterotoxin is a type of exotoxin effective on the intestines.

Exotoxins are more potent and often fatal when compared to endotoxins. The deadliest toxin in the world – Botulinum toxin or Botox is produced by the bacterium Clostridium botulinum. 2018-01-21 Endotoxin also known as lipoglycans is a toxic heat-stable lipopolysaccharide substance present in the outer membrane of gram-negative bacteria that is released from the cell upon lysis. Endotoxins are not secreted but are released only when the cells are disrupted, they are less potent and less specific than the exotoxins and do not form toxoids. 2021-04-08 2014-04-23 Start studying Microbiology - Endotoxin vs Exotoxin.

Basic properties and differences between Exotoxins and Endotoxins Endotoxins vs Exotoxins (Difference between Bacterial Endotoxin and Exotoxin) Microbial toxins are noxious substances produced by the microorganisms such as bacteria and fungi in order to promote their pathogenicity and disease-causing process. Endotoxin. Endotoxins are heat tolerant and relatively stable at 250oC for one hour. Exotoxin. Exotoxins can get destroyed at 600-800C (heat liable). They are unstable except Staphylococcal enterotoxin.
