Illustration depiction cycle of malaria. A female Anopheles mosquito injects sporozoites (bottom left) into a human or other vertebrate circulatory system while feeding on blood. The sporozoites travel to the liver where they reproduce asexually resulting in thousands of merozoites (blue droplets). These destroy their host liver cells and go on to infect red blood cells (pink glob bottom centre) and a second reproductive cycle begins. Some may become gametocytes (pink triangular shapes) which go on to infect other mosquitoes. The malarial parasite manages to avoid the immune system of its secondary host by spending most of its life cycle within cells. Many infected blood cells manage to avoid destruction in the spleen by sticking to the walls of blood vessels | |
