Pyrogens are polypeptides, which produced by metabolic process. When released into blood stream produce fever. Pyrogens can be produced by bacteria, yeast, moulD’s and viruses.
But, endotoxin is toxin which is produced inside gram negative bacteria which will release after cell lysis. Endotoxins are lipopolysaccharide.
