Lipopolysaccharides (LPS), also known as lipoglycans and endotoxins, Endotoxins are part of the outer membrane of the cell wall of Gram-negative bacteria. Although the term "endotoxin" is occasionally used to refer to any cell-associated bacterial toxin, in bacteriology it is properly reserved to refer to the lipopolysaccharide complex associated with the outer membrane of Gram-negative pathogens such as Escherichia coli, Salmonella, Shigella, Pseudomonas, Neisseria, Haemophilus influenzae, Bordetella pertussis and Vibrio cholerae.
