How is Plasmodium (The Parasite that causes Malaria) injected into a mosquito?
Wikipedia is a good place to start for questions like this. Plasmodium has a complex life cycle, and changes into multiple different forms during its cycle, part of which is in the human or other animal and part in the mosquito. Basically it goes: Sporozoite is injected with mosquito saliva into the human, migrates to liver, changes to hypnozoite then multiplies into merozoites, then migrate to red blood cell, grow into trophozoites, divide as schizonts, and produce new merozoites. This cycle continues in the red blood cell and new merozoites invade new red blood cells, but some merozoites differentiate into male and female gametocytes. The female mosquito takes these into her midgut with the blood meal where they differentiate into gametes, fetilise each other to produce motile zygotes called ookinetes which migrate to the outside of the mosquito’s gut and then change into sporozoites which then migrate to the mosquito’s salivary glands ready to be injected into the next host. And the
