Abstract
Gram-negative bacteria cause the majority of fatal infections in developed countries, usually in association with septic shock or meningitis. The pathophysiology of gram-negative bacterial infection is thought to be mediated in large part by lipopolysaccharide (LPS), a toxin elaborated by all species of gram-negative bacteria [1]. LPS is a structural component of the gram-negative bacterial cell envelope, and is therefore known as endotoxin. Gram-positive bacteria do not synthesize LPS. The lack of LPS in the cell envelope of grampositive organisms versus its presence in the gram-negative envelope accounts for the difference in staining characteristics of these two major categories of bacteria.
