A. Effect of P. falciparum on erythrocyte deformability: stiffness, g′ (closed data symbols), and friction, g″ (open data symbols), of CS2 infected erythrocytes, measured at frequencies from 0.1 to 100 Hz, CS2 (n = 16). Stiffness (grey continuous line) and friction (grey dashed line) of uninfected erythrocytes. Data points are geometric means and SD.
B. Stiffness data of CS2Pf332trunc- (n = 18) and CS2ΔPf332- (n = 15) infected erythrocytes, normalized by the parental line CS2. All data are geometric means and SE, and are taken at 0.75 Hz. Black dashed line at 100% represents CS2 and grey dashed line is the stiffness of the uninfected erythrocytes.
