Various modes. Heat stability of Endotoxins and Exotoxins. Endotoxin. Endotoxins are heat tolerant and relatively stable at 250oC for one hour. Exotoxin Endotoxins and exotoxins are among the most potent bacterial inducers of cytokines. During infectious processes, the production of inflammatory cytokines including tumor necrosis factor (TNF), interleukin-1β (IL-1β), gamma interferon (IFNγ) and chemokines orchestrates the anti-infectious innate immu … Exotoxin has the ability to trigger immune responses whereas endotoxin cannot trigger an immune response; Exotoxin tends to stay active beyond 60 degrees whereas endotoxin tends to stay active beyond 100 degrees Celcius.

– Animals vary in their susceptibility to endotoxin. Exotoxins and Endotoxins • Compared to the classic exotoxins of bacteria, endotoxins are less potent and less specific in their action, since they do not act enzymatically. As nouns the difference between exotoxin and hemolysin is that exotoxin is any toxin secreted by a microorganism into the surrounding environment while hemolysin is (medicine) any substance (often an exotoxin) that damages the membranes of red blood cells and thus releases hemoglobin.
