94 ligands
Description
The collective lifecycle stage that occurs as a result of asexual replication in erythrocytes of the host organism and can include:
  • erythrocytic merozoite, non-motile but recognises specific proteins on the surface of the erythrocyte and has an apical complex that facilitates entry into the host cell. This form of the parasite is also found in host hepatocytes (see hepatic merozoites).
  • trophozoite, the intracellular trophic form that develops from the merozoite. The young trophozoite has a distinctive 'ring' morphology in Geimsa-stained blood smears but this disappears as the parasite grows in size. During the trophic period the parasite ingests the host cell cytoplasm and breaks down the haemoglobin, producing non-toxic hemozoin as a by-product. After feeding and growth is complete the trophozoite undergoes asexual reproduction (schizony) and develops into a schizont.
  • erythrocytic schizont, a multinucleate form of the parasite that develops in erythrocytes from the trophozoite by schizogony with incomplete cytokineses. This developmental form is also found in host hepatocytes (see hepatic schizont).
Completion of cytokinesis produces several thousand merozoites from a single schizont, leading to rupture of the infected erythrocyte and release of merozoites into the bloodstream. These merozoites invade new erythrocytes and initiate either another cycle of schizogony or, under certain conditions, a small percentage of merozoites commit to sexual reproduction instead (see Plasmodium sexual blood stage).
It is the repeated cycles of schizogony in erythrocytes that leads to clinical symptoms: the simultaneous rupture of infected erythrocytes and the associated release of antigens and waste products accounts for the intermittent bouts of fever associated with malaria. As a result, almost all available antimalarial therapies target the asexual blood stage.
