Resealed erythrocytes were infected with mature schizont stage parasites and the parasitemia estimated at different time-points by Giemsa-stained blood smears along with counting of ring- or schizonts-infected erythrocytes. a Light microscopy images of Giemsa-stained blood smears at different time points. Scale bar 2 μm. b Schematic representation of the proposed mechanism of parasite infection in loaded erythrocytes. c Fold-change in parasitemia of each sample after 48 h of infection compared to control at the time of infection. d Evaluation of merozoite invasion after 56 h into erythrocytes loaded with respective recombinant proteins. Invasion observed in untreated erythrocytes was considered as 100%. Invasion was reduced by 60% in rTNT-loaded erythrocytes that was successfully recovered with rIFT. The data represent mean of three independent experiments and error bar shows standard deviation. Statistical significance of difference was calculated using unpaired t-test with Welch’s correction (*P < 0.05, **P < 0.01, ***P < 0.001).
