Platelet-mediated clumps of P. falciparum infected erythrocytes (IE) detected by in vitro clumping assays. A. Platelet-mediated clumps of infected erythrocytes (IEs) from P. falciparum clone HB3 viewed by ethidium bromide staining and fluoresence microscopy (400×) of a wet preparation. Uninfected erythrocytes (Es) present in the clumping assay are unstained. B. Platelet-mediated clumps of HB3 IEs observed by Giemsa-stained thin smears and light microscopy (1000×).
