Which disease is caused by Coxiella burnetii?

Q fever Tularemia Leptospirosis Botulism

Correct Answer:

Q fever

Explanation:

Q fever is caused by Coxiella burnetii, a small intracellular bacterium commonly carried by cattle, sheep, and goats. Humans usually pick it up by inhaling aerosols from birth products or contaminated dust. The illness often starts with sudden fever and flu‑like symptoms, and it can affect the lungs or liver; some individuals may develop chronic infection such as endocarditis, especially if there is underlying heart disease. This distinguishes it from other illnesses listed, which are produced by different pathogens: tularemia by Francisella tularensis, leptospirosis by Leptospira, and botulism by toxin from Clostridium botulinum.
