CPE uses the tight junction proteins claudin-3 and -4 as receptors prior to forming a pore in the host cell membrane (Figure 77.4).175,176 The CPE binding site in claudin-3 has been localized to the second extracellular loop. 2018-01-21 This medical microbiology lecture talks about exootoxin and the bipartile nature of it and the secretion of it. It also explains the toxic effects of exotoxi The discovery that cholera is caused by a potent exotoxin (cholera enterotoxin) affecting intestinal permeability, the demonstration that bacteria-free culture filtrates of Vibrio cholerae were enterotoxic, and the development of a reproducible animal model for the disease are considered milestones in the history of the fight against cholera. Exotoxin: Distinct toxic mechanism (Cardiotoxin would affect heart) Endotoxin: Systemic response, fever, decrease in BP, DIC (Endotoxic Shock) So take the bacteria, modify them then put them in a vaccine.

Exotoxin vs enterotoxin

Enterotoxin is a type of exotoxin which is released to the intestine of organisms. An enterotoxin is a protein exotoxin released by a microorganism that targets the intestines. Enterotoxins are chromosomally encoded or plasmid encoded exotoxins that are produced and secreted from several bacterial organisms. They are heat labile, and are of low molecular weight and water-soluble.

Exotoxins are toxic substances that are secreted by bacteria outside of their cell. While the endotoxins are toxins located within the cell membrane.

Bacterial superantigens like the Staphylococcus enterotoxin A (SEA) is a soluble exotoxin with the potential to stimulate strong V-beta specific T cell responses when bound to MHC class II molecules.

There is a diverse range of exotoxin which are classified according to their site of action namely they are cytotoxin, a neurotoxin, enterotoxin, leukotoxin.
