Caption:
Normal red blood cell (erythrocyte) and red blood cell infected with the malaria parasite (Plasmodium falciparum, schizont stage).Note in the upper right red blood cell there is a large protrusion that is the schizont stage of the malaria parasite that is dividing and growing in the red blood cell. Malaria is caused by Plasmodium spp., parasitic single-celled protozoans called plasmodia. Malaria is spread to humans by species of tropical mosquitoes (Anopheles species). Infection spreads from the liver to the blood, where the plasmodium multiplies inside red blood cells. The plasmodial parasite reproduces asexually in the red blood cells significantly destroying many red blood cells. There are four stages of the parasite that develop in human red blood cells - merozoite stage, ring stage, trophozoite stage and schizont stage. Release of mature Plasmodium merozoites results in further infection and produces bouts of shivering fever (paroxysms) and sweating that may be fatal.
