    At the schizont stage, the parasite replicates its DNA multiple times and multiple mitotic divisions occur asynchronously.

    Meiosis takes place inside the sporoblast to produce over 3, haploid daughter cells called sporozoites on the surface of the mother cell. Cell Rep. Merozoites continue the asexual cycle and infect new red cells; A few differentiate into male or female gametocytes sexual formswhich cause no symptoms.

    1. Additionally, free heme is released into the peripheral blood which is an important stimulus for endothelial activation Red cell lysis stimulates release of proinflammatory cytokines such as tumor necrosis factor TNF. The function of Maurer's clefts tethering is unknown, but it could potentially contribute to its function as a trafficking hub.
