Which term describes a toxic bacteria in the bloodstream?

• A. Septicaemia
• B. Sepsis
• C. Pyemia
• D. Endotoxaemia

Answer: (A)

Septicaemia is the presence of viable bacteria in the bloodstream, often with toxins released into the blood that cause widespread symptoms. This directly matches the idea of “toxic bacteria in the bloodstream,” since the focus is on bacteria existing in the circulation and the toxins they produce.

Sepsis, by contrast, is the body’s systemic inflammatory response to an infection, not necessarily the bloodstream harboring bacteria itself. Pyemia refers to pus-forming bacteria circulating in the bloodstream and forming abscesses, a more specific scenario than just bacteria in the blood. Endotoxaemia means endotoxins from Gram-negative bacteria are in the blood, not the bacteria themselves.
