Is LPS Equal to Endotoxin?

Abstract:

Lipopolysaccharide (LPS) is the major component of the cell wall of Gram-negative bacteria, and is also associated with the pathogenicity of bacteria closely. But it has been a major mistaken ideas for a long time to define LPS as endotoxin in the teaching of Medical Bacteriology. And which might prevent students to study and understand the pathogenicity of bacteria correctly also. So here we offer some initial ideas for discussion.
