(A) Immunohistochemistry for CD61 (Glycoprotein IIIa) shows numerous megakaryocytes and platelets (small punctate bodies) in alveolar capillaries. From Houston Case Two (HC2). (Magnification bar, 20 µm). (B) Electron micrograph shows a collection of viral particles in a vacuole inside a renal glomerular endothelial cell from Houston Case One (HC1). X50,000. (C) Electron micrograph of a single 100 nanometer viral particle free in the cytoplasm of a renal glomerular endothelial cell from HC1. Note the nucleocapsid and membrane spike proteins. X50,000.
