Question

Quizplus · Accepted Answer

Endotoxins are lipopolysaccharides (LPS) present in the outer membrane of gram-negative bacteria. They are released when the bacterial cell is lysed and can cause fever, inflammation, and septic shock in the host. Gram-positive bacteria may produce exotoxins but not endotoxins as they lack the outer membrane containing LPS. Gram-negative and gram-positive fungi do not produce endotoxins as they have a different cell wall composition.
