Exotoxins, in contrast to endotoxin, are diffusible proteins secreted into the external medium by the pathogen.Most pathogens secrete various protein molecules that facilitate adhesion to, or invasion of, the host.

Secreted by living bacteria (usually gram-positive) into surroundings. · Proteins - easily destoryed by heat · Leathal does is small · Specific - targets certain organs/

Exotoxins – Tetanus, diphtheria, Scarlet fever, gas gangrene, scalded skin syndrome, antibiotic-associated diarrhea, and botulism, to name a few. Endotoxins – Meningococcemia, Urinary tract infections, meningococcal meningitis, Typhoid fever, Coronary artery disease, sepsis by gram-negative rods and hemorrhagic shock.

They are secreted following lysis into the surrounding medium. They are proteins and many are enzymes that catalyze certain biochemical reactions. The genes for most exotoxins are carried on bacterial plasmids or phages.

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

They are soluble proteins that acts as enzymes. An exotoxin has the ability to cause damage to the host by destructing cells or interfering with the normal cell metabolism.

What are Endotoxins?3.

Exotoxins are contagious toxins that spread from the focus of infection to other parts of the body and cause damage. They are soluble proteins that acts as enzymes. An exotoxin has the ability to cause damage to the host by destructing cells or interfering with the normal cell metabolism.

Production: It is released out of living bacterial cell: It is a component of bacterial cell wall: 2. Chemical composition Exotoxins are toxic substances secreted by bacteria and released outside the cell. Whereas Endotoxins are bacterial toxins consisting of lipids that are located within a cell. Following are the few differences between exotoxin and endotoxin. Characteristics Exotoxins Endotoxins Source Living gram positive and gram negative bacteria Lysed gram negative bacteria Location Released from the cell There is more molecular variety in exotoxins than in the LPS scaffold of endotoxins.

Types. Many exotoxins have been categorized. This classification, while fairly exhaustive, is not the only system used. Other systems for classifying or identifying toxins include: . By organism generating the toxin; By organism susceptible to the toxin; By secretion system used to release the toxin (for example, toxic effectors of type VI secretion system); By tissue target type susceptible

Being an enzyme, it can catalyze many biochemical reactions, and it is reusable. A small amount of exotoxins is enough to generate toxicity. 2007-06-08 · Exotoxins are produced inside mostly gram-positive bacteria as part of their growth and metabolism.

Exotoxins: Toxins that are released extracellularly as the organism grows are called exotoxins. Exotoxins may travel from a focus of infection to distant part of the body and cause damage. E.g. Neurotoxin (botulinum toxin, tetanus toxin), Enterotoxin (cholera toxin), Cytotoxin. Endotoxins:

-lethal -enzymatic protein soluble in the blood and lymphatic…. 11 Terms. Exotoxins are _____. a. proteins secreted by living bacterial cells b. only released after a cell is damaged or lysed c.
