Abstract

Q fever is a zoonotic infection caused by Coxiella burnetii. Acute Q fever usually develops as a self-limited flu-like illness, atypical pneumonia, or hepatitis. We experienced a case of Q fever in a 50-year-old male who had a prolonged fever. The bone marrow and lymph node biopsy revealed fibrin-ring granulomas, which is a distinct finding of Q fever. The diagnosis was proven by high titers of C. burnetii anti-phase II antibody (IgM 1:512 and IgG >,048) and positive nested PCR for the com-1 gene. Q fever is rare in Korea, but should be considered in the differential diagnosis of fever of unknown origin
