TOXINS-Differences Between Exotoxins and Endotoxins

What is TOXINS-Differences Between Exotoxins and Endotoxins

Microorganisms produce toxins or poisonous substances by their development. Toxins are mind boggling proteins or substances much like proteins. There are two kinds of toxins; to be specific exotoxins and endotoxins. A few microbes structure the two exotoxins just as endotoxins. We will now concentrate on these two sorts of toxins.


Exotoxins are commonly created by Gram positive microscopic organisms and discharged into their environment, for example Shigella dysenteriae; Cholera vibrio; Corynebacterium diphtheriae;Clostridium tetani; Clostridium welechii. Exotoxins are insecure and normally wrecked by a temperature above 65oC. They are exceptionally antigenic and produce killing antitoxins.


Endotoxins are created essentially by Gram negative microscopic organisms and stay limited to the collection of microorganisms and not discharged into their environment. They are liberated just when the microorganisms are separated. They are less harmful than exotoxins. They are pitifully antigenic and have no enzymatic activity. They are heat stable and can withstand bubbling water for a variable period. Endotoxins don’t deliver killing antitoxins however produce agglutinins, precipitins and so forth., for example Vibro cholerae, Salmonella typhosa, and so forth.

Explicitness of Toxins

The poison of every microorganism is explicit and contrasts synthetically from all others. Models:

I) Diphtheria poison is an exotoxin and harms kidney, sensory tissue and heart.

ii) Tetanus poison likewise is an exotoxin and harms certain nerves and creates fits of lock jaw.

iii) Staphylococci radiate a few toxins and cause food contamination.

Differences Between Exotoxins and Endotoxins

What is increasingly risky endotoxin or exotoxin?

Exotoxins are deadly even in little amounts. Luckily, there are immunizations accessible to battle them. Then again, endotoxins are less deadly however can make fever the host. Exotoxins are emitted by microbes and discharge outside the cell while endotoxins are bacterial toxins situated inside the cells
