An outline of the invasion mechanism used by Theileria, Plasmodium, Toxoplasma, Cryptosporidium, and Babesia. The figure is the representation of the invasion process, which happens during interna-lization of Theileria, Plasmodium, Toxoplasma, Cryptosporidium, and Babesia. The apical region of all the parasites faces toward the cell surface for their entry. In Plasmodium, invasion occurs in two types of cells, erythrocyte (non-nucleated cell) and hepatocyte (nucleated cell) as compared to other parasites where invasion occurs in the nucleated cell.
