What is Endotoxin and Exotoxin? Endotoxin:Endotoxins are potentially hazardous complex chemicals that are frequently generated by Gram-negative bacteria. They were first identified in the late 19th century. Endotoxins, sometimes referred to as lipopolysaccharides (LPS), are among the most prevalent pyrog...
Endotoxin, a cell wall component of gram-negative bacteria, is known to activate the cytokine pathways that lead to the release of proinflammatory mediators, which results in a wide range of pathophysiological effects. Recent advances in molecular biology and mostly immunology have greatly contributed ...

Endotoxins are promoters of inflammation; the most potent endotoxin is the lipopolysaccharide (LPS) produced by Gram-negative bacteria. In addition, in Gram-positive bacteria peptidoglycan and teichoic acid are also endotoxins. The toxic effects of endotoxins include leukopenia followed by leukocytosis, ...
