Exotoxins are usually heat labile proteins secreted by certain species of bacteria which diffuse into the surrounding medium. Endotoxins are heat stable lipopolysaccharide-protein complexes which form structural components of cell wall of Gram Negative Bacteria and liberated only on cell lysis or death of bacteria. Enterotoxins are chromosomally encoded or plasmid encoded exotoxins that are produced and secreted from several bacterial organisms. They are heat labile (>60⁰), and are of low molecular weight and water-soluble. An enterotoxin is a protein exotoxin released by a microorganism that targets intestines. Enterotoxins are produced in or released into intestines. Certain bacterial species are capable of producing enterotoxins.

Endotoxin vs Enterotoxin: Az endotoxin egy bakteriális toxin, amely a lipopoliszacharidokból álló baktériumsejt része. Az enterotoxin a beleket megcélzó mikroorganizmus által kibocsátott fehérje exotoxin. Baktériumcsoportok: Az endotoxinokat gram-negatív baktériumok termelik. Exotoxins are highly potent and can cause extreme harm to the host.

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. Then the individual can make a antibodies against it and build immunity The toxin can be informed of endotoxin, exotoxin, and enterotoxin.

Endotoxins: Exotoxins are toxic substances that are secreted by bacteria outside of their cell. While the endotoxins are toxins located within the cell membrane. Exotoxin Endotoxin : Produced by both Gram-positive and Gram-negative bacteria : Produced only by Gram-negative bacteria : Released from cell : Integral part of cell Endotoxin is an integral part of the cell wall of the bacteria whereas exotoxin is secreted by the bacteria.
