Case 79
A physician was admitted to a hospital in January 2002 with a 3-week history
of fever. He was treated empirically for pneumonia. He reported
no recent travel outside the U.S. He reported no history of blood
transfusions or intravenous drug use, and no needle sticks or cuts while
performing surgery or other procedures. Blood smears were made from
blood collected 1 day after this treatment. They were stained with
Wright’s-Giemsa and examined by the hospital laboratory and CDC (Figures
A through G). The images were captured from one of
the blood smears. What is your diagnosis? Based on what criteria?
