Endotoxin also known as lipoglycans is a toxic heat-stable lipopolysaccharide substance present in the outer membrane of gram-negative bacteria that is released from the cell upon lysis. Endotoxins are not secreted but are released only when the cells are disrupted, they are less potent and less specific than the exotoxins and do not form toxoids.

Toxins are small molecules, peptides, or proteins produced by living cells that are capable of causing diseases or structural damage when they come in contact or are absorbed by tissues. An exotoxin can cause damage to the host by destroying cells or disrupting normal cellular metabolism.

e. endotoxiner och exotoxiner produceras, och dessa kan särskiljas av deras kemiska natur. Endotoxiner är lipopolysackarider och exotoxiner är Exotoxin produceras för att vara toxiska (till skillnad från endotoxin, som är en del av gramnegativa bakteriers yttre cellmembran men fungerar som toxin efter bakteriens död.) Ett exotoxin är ett protein som kan skada värden genom att förstöra celler eller störa dess metabolism . Endotoxin. Hoppa till navigering Hoppa till sök.

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. Bacteria release substances that are harmful to the host.

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.

Kemisk substans som utsöndras av till exempel bakterier,. endotoxiner och exotoxin fungerar som två klasser av toxin som produceras av bakterier och andra mikroorganismer. Dessa molekyler skiljer sig i sin förmåga  Teikoinsyra finns bara hos grampositiva bakterier.

24 Sep 2012 A direct contact between bacteria and macrophage and not mycobacteria are not known to produce endotoxins or exotoxins that are known 

Endotoxin and exotoxin are two types of toxins produced by bacteria. The key difference between endotoxin and exotoxin is that the endotoxin is a lipopolysaccharide while exotoxin is a protein. Furthermore, endotoxins are heat stable while exotoxins are heat labile. Furthermore, exotoxins act as enzymes while endotoxins are not. Exotoxins are lethal even in small quantities.

The name endotoxin is derived from the fact that these toxins are generally cell bound and released only when the cell lyses. Basic properties and differences between Exotoxins and Endotoxins Endotoxins vs Exotoxins (Difference between Bacterial Endotoxin and Exotoxin) Microbial toxins are noxious substances produced by the microorganisms such as bacteria and fungi in order to promote their pathogenicity and disease-causing process. Endotoxin. Endotoxins are heat tolerant and relatively stable at 250oC for one hour. Exotoxin. Exotoxins can get destroyed at 600-800C (heat liable). They are unstable except Staphylococcal enterotoxin.
