Study Notes
Extracellular Toxins
- Commonly referred to as exotoxins
Endotoxins
- Characterized by being lipopolysaccharide (LPS) components of the outer membrane of Gram-negative bacteria
Exotoxins vs. Endotoxins
- Exotoxins are proteins secreted by bacteria, while endotoxins are part of the bacterial cell wall
Bacterial Toxins
- Exotoxins are highly potent and can cause specific symptoms, even in small amounts
- Endotoxins are less potent than exotoxins but can cause a strong inflammatory response
Endotoxin Risk
- Endotoxins pose a greater risk during bacterial infections due to their release when bacteria die or are lysed
