  1. Pf P. falciparum, UN uncomplicated malaria, SM severe malaria. The number of adherent pRBC was determined microscopically; OD optical density. The mean OD was determined for each isolate. Using a positivity cut-off of 3; 3D71: positive control for the first experiment. 3D72.3.…10: positive control for the remaining experiments; RBC1: negative control for the first experiment.
