Infected red blood cell in close contact with endothelium in ALI/ARDS lungs. Infected erythrocytes were seen in close contact with endothelium in both non-congested (A, B and C) and congested capillaries (D, E and F). Bridges between the infected erythrocyte and endothelium could be observed (B, C, E and F). Representative images taken by TEM. ALI/ARDS lung, lung from DBA/2 mouse that died with acute lung injuy/acute respiratory distress syndrome after infection with P. berghei ANKA; iRBC, infected red blood cell; arrow heads, points of contact.
