Document Summary
Mosquito injects sporozoite malaria infected saliva into human blood to stop clotting. Asexual reproduction of merozoite parasites occurs in human liver cells. Her feeding becomes less ef cient and she feeds more often and for longer. Infected pregnant female requires blood meal to produce eggs. Cysts release many tiny sporozoite parasites that infest mosquito"s salivary glands. Sporozoite parasites migrate to the lining of the mosquitos stomach and produce large cysts. Liver cells burst open with thousands of merozoite parasites. Parasites travel from liver to the blood stream. Apical complex of plasmodia helps to dissolve away rbc membrane. Parasites devour contents of cell and create more parasites. Rbc becomes sticky and sticks to blood vessel walls. Defective rbcs never reach the spleen to be ltered out. Parasites mature and burst out of cell releasing more parasites into the blood stream. Mature sexual reproduction of gametocytes occurs inside mosquito. Healthy mosquito bites infected human and gametocyte parasites transfer disease into mosquito.
