The part of the component in bacteria that, when released, can cause fever in dialysis patients is which of the following?

• A. Exotoxin
• B. Capsule
• C. Endotoxin
• D. Peptidoglycan

Answer: (C)

Endotoxins are the part of Gram-negative bacteria that, when released into the bloodstream, trigger fever. They are lipopolysaccharide (LPS) components of the bacterial outer membrane. In dialysis, endotoxin exposure often comes from contaminated dialysate or water, and when endotoxin enters the circulation it activates immune cells to release cytokines like IL-1 and TNF-alpha, causing fever. Exotoxins are secreted toxins that cause disease by different mechanisms, so fever isn’t the specific clue here. Capsule and peptidoglycan aren’t the primary fever-inducing factors in this context.
