Because Plasmodium falciparum replicates inside of a parasitophorous vacuole (PV) within a human erythrocyte, parasite egress requires the rupture of two limiting-membranes. Parasite Ca2+, kinases, and proteases contribute to efficient egress; their coordination in space and time is not known. Here the kinetics of parasite egress were linked to specific steps with specific compartment markers, using live cell microscopy of parasites expressing PV-targeted fluorescent proteins, and specific egress inhibitors. Several minutes before egress, under control of parasite [Ca2+]i the parasitophorous vacuole began rounding. Then after ~1.5 minutes, under control of PfPKG and SUB1, there was abrupt rupture of the PV membrane and release of vacuolar contents. Over the next ~6 minutes there was progressive vacuolar membrane deterioration simultaneous with erythrocyte membrane distortion, lasting until the final minute of the egress program when newly-formed parasites mobilized, erythrocyte membranes permeabilized and then ruptured – a dramatic finale to the parasite cycle of replication.
