CM (B). HO-1 staining of tissues from cerebral malaria cases showing apparently absent physical brain pathology, but sequestered parasites common. A and B brain, C and D lung, and E and F liver. The left hand column (A, C and E) is from an example (case 25) of the more common (4 of 7) combination, in which cerebral vasculature monocytes were not common, though parasite sequestration sometimes intense. B, D and F are from case 21. As in both examples, monocytes in lung, and Kupffer cells, were commonly strongly stained. Scale bar, 100 μm.
