Escherichia coli Lipopolysaccharides; E. coli LPS

This refers to the lipopolysaccharide (LPS) found in the outer membrane of Escherichia coli, a Gram-negative bacterium. LPS is a potent immunostimulant and a major endotoxin, triggering strong innate immune responses in animals. Its structure can vary between different E. coli strains, influencing the host's response.
