Summary – Endotoxin vs Exotoxin. Endotoxin and exotoxin are two types of toxins produced by bacteria. The key difference between endotoxin and exotoxin is that the endotoxin is a lipopolysaccharide while exotoxin is a protein. One example is that of StxB which specifically binds with CD77 (Gb3) which shows expression on the surface of cancerous cells such as colon, pancreas, breast, and many more.

Endotoxin and exotoxin are two types of toxins produced by bacteria. The key difference between endotoxin and exotoxin is that the endotoxin is a lipopolysaccharide while exotoxin is a protein. One example is that of StxB which specifically binds with CD77 (Gb3) which shows expression on the surface of cancerous cells such as colon, pancreas, breast, and many more. Once StxB targets a cancerous cell, it delivers the A subunit of the toxin which eventually kills the cancerous cell.

Pathogens & Disease Pathogens are defined as microbes capable of causing host damage. When host damage reaches a certain threshold, it can manifest itself as a disease. The evolution of an infectious disease in an individual involves complex interactions between the pathogen and the host.

Shiga toxin, also known as Stx, is a toxin that is produced by the rod shaped Shigella dysenteriae and Escherichia coli (STEC). Food and drinks contaminated with these bacteria are the source of infection and how this toxin is spread. Symptoms include abdominal pain as well as watery diarrhea. Examples of A-B toxins include: Diphtheria exotoxin, produced by Corynebacterium diphtheriae (inf).

Suggested importance of monokines in pathophysiology of endotoxin shock and malaria. Early expression of intercellular adhesion molecule-1 in the corneal endothelium stimulated by endotoxin: an immuno-scanning electron microscopical study. The exotoxin production is diversified in a few strains of bacterial species while mostly it is the same in all. In a few species, toxin production is associated with the lysogenic phase. There is a diverse range of exotoxin which are classified according to their site of action namely they are cytotoxin, a neurotoxin, enterotoxin, leukotoxin. Plural form of exotoxin.
