A 28 year old male undergoes induction chemotherapy for acute
myelogenous leukemia. He becomes severely pancytopenic, with a
WBC count of 1320/microliter, Hgb 7.9 g/dL, and platelet count of
72,000/microliter. He becomes comatose. A CT scan of the head
reveals a right parietal hemorrhage. He dies a day later. At
autopsy, he is found to have a right middle cerebral arterial
thrombosis with right parietal hemorrhagic infarction. Which of the
following infectious agents is most likely to produce these findings:
A Herpes simplex virus
B Toxoplasma gondii
C Human immunodeficiency virus
D Cytomegalovirus
E Aspergillus niger
