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.

Endotoxins vs Exotoxins. The main difference between endotoxins vs exotoxins is that Endotoxins bacterial toxic substances that are structural components of certain bacteria and release only during lysis of a bacterial cell. While Exotoxins are not structural components, but simply substances release externally by the bacterium.

Fortunately, there are vaccines available to fight them. On the other hand, endotoxins are less lethal but can cause fever to the host.

The toxic activity of LPS was first discovered and termed "endotoxin" by Richard Friedrich Johannes Pfeiffer, who distinguished between exotoxins, which he classified as a toxin that is released by bacteria into the surrounding environment, and endotoxins, which he considered to be a toxin kept "within" the bacterial cell and released only after destruction of the bacterial cell wall.

Differences between Exotoxins and Endotoxins. 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. Discovery.
