Which term refers to a bloodstream infection characterized by bacteria circulating in the blood, often with systemic illness?

• A. Bacteremia
• B. Septicemia
• C. Sepsis
• D. Pyemia

Answer: (B)

When a bloodstream infection is described, the phrase focuses on bacteria actually circulating in the blood and the accompanying systemic illness. That combination is what septicemia captures: bacteria in the bloodstream causing a body-wide response. Bacteremia means bacteria are present in the blood, but it doesn’t necessarily imply illness beyond the bloodstream. Sepsis refers to the body’s widespread inflammatory response to infection, which can happen with septicemia but centers on the host’s reaction rather than the mere presence of bacteria in the blood. Pyemia describes pus-forming infection in the bloodstream, often with abscess-related spread, but it’s a more specific and less general term. So the term that best matches “a bloodstream infection with bacteria circulating in the blood, often with systemic illness” is septicemia.
