Figure 4.
Images of P. vivax parasites infected on cultured erythropoietic cells. Thin smears were made on glass slides, stained with Giemsa and observed under microscope (A–C), or fixed and immuno-stained with antibodies (D and E). A and B, P. vivax-infected reticulocytes 24 and 48 hours PI, respectively. C, P. vivax-infected erythroblast 48 hours PI. D, UV-microscope image of P. vivax-infected reticulocyte stained with anti-P. vivax MSP-1 (green) and anti-human glycophorin A (red). E, differential interference image of the same field as E. Human erythropoietic cells which stained red are indicated by arrows.
