Figure 2

No staining for N protein is present in the bronchus of HK case 1 (A), but there is focal positive staining of bronchiolar epithelium in this case (B). Positive staining is seen in epithelial cells and detached cells in the alveoli in TO case 1 (C), which on higher magnification morphologically resemble type 1 pneumocytes (D). In TO case 2, there is a thrombus present which contains mononuclear and spindle-shaped cells (E). Carbon-containing macrophages are also positive (F). Ten days after symptom onset, positive staining was reduced and is noted mainly in the exudates (G) with only very focal positive mononuclear cells seen (H). AEC stain with hematoxylin counterstain; magnification 100×.
