  1. Parasites underwent separation by use of a Percoll gradient (Percoll invasion column) or passage through a magnetic beads column (MB invasion column). The collected schizonts were then placed in culture with new red blood cells to allow for a new round of infection by the parasite. The parasitaemia was calculated by flow cytometry except for experiments marked with "*" which were determined by light microscopy.
