Endotoxins also called LPS are the component of the outer membrane of gram-negative bacteria and are released into the circulation upon disruption of the intact bacteria death cell lysis 231. Endotoxin is a lipopolysaccharide component of the Gram-negative bacteria cell and is released during active cellular growth and after cell lysis.
