A 36-year-old man with AIDS develops right-sided weakness involving the lower, but not the upper, limb. MRI scans reveal a ring-enhancing lesion within the white matter of the left frontal lobe. A biopsy shows coagulative necrosis of brain parenchyma with macrophage-rich chronic inflammatory infiltration admixed with microscopic cysts that contain characteristic bradyzoites. Which of the following is the most common source of this type of infection?
A. Anopheles mosquitoes
B. Bird droppings
C. Cats
D. Cooling systems
E. Washbasins

agree. its C. the finding of bradyzoites is confirmatory. toxoplasma is one of the most common protozoa infections in AIDS patients.
