  • a LN, lymph node; N, negative; P, positive.

  • b Detection of p24 antigen in autopsy samples by immunocytochemistry; positive samples were graded on a scale from + (sparse) to +++ (frequent), based on numbers of infected cells.

  • c p24 antigen expression detected in cells of monocyte/macrophage lineages is indicated on a scale of ⊕ (sparse), to ⊕⊕⊕ (frequent). LF, left frontal region of the brain; CO, colon; LU, lung.

  • d –, not detected.
