Difference Between Endotoxins and Exotoxins

Difference Between Endotoxins and Exotoxins

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.

How are Exotoxins different from endotoxins quizlet?

Endotoxins are part of the Gram (-) bacterial cell wall and are Lipids + Sugars while Exotoxins typically come from Gram (+) bacteria and are PROTEINS that are excreted.

Which is worse endotoxin or exotoxin?

Endotoxins are the lipopolysaccharide-protein complexes (LPS), responsible for making an integral part of the cell wall of Gram-Negative Bacteria. Exotoxins are the proteins which are secreted by a few species of bacteria. Though endotoxins are considered to be more toxins than exotoxins.

What are examples of endotoxins?

Although the term "endotoxin" is occasionally used to refer to any cell-associated bacterial toxin, in bacteriology it is properly reserved to refer to the lipopolysaccharide complex associated with the outer membrane of Gram-negative pathogens such as Escherichia coli, Salmonella, Shigella, Pseudomonas, Neisseria, ...

What is an example of an exotoxin?

An exotoxin is a toxin secreted by bacteria. ... Well-known exotoxins include: botulinum toxin produced by Clostridium botulinum; Corynebacterium diphtheriae toxin, produced during life-threatening symptoms of diphtheria; tetanospasmin produced by Clostridium tetani.

What do endotoxins and Exotoxins have in common?

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.

What is meant by endotoxin?

: a toxic heat-stable lipopolysaccharide substance present in the outer membrane of gram-negative bacteria that is released from the cell upon lysis.

Why is endotoxin so harmful?

Endotoxins are lipopolysaccharides found in the cell wall of Gram-negative bacteria, which can induce inflammation and fever as an immune response in higher organisms. Reaction to endotoxins can lead to anaphylactic shock and death of patients.

What are the three types of Exotoxins?

There are three main types of exotoxins:

How do you treat endotoxins?

Endotoxin can be inactivated when exposed at temperature of 250º C for more than 30 minutes or 180º C for more than 3 hours (28, 30). Acids or alkalis of at least 0.1 M strength can also be used to destroy endotoxin in laboratory scale (17).
