oocyst

A structure that develops on the outer wall of the mosquito's stomach from the fertilized malarial parasite. The parasite divides repeatedly within the oocyst which rapidly fills up with the infective form of the parasite (SPOROZOITES) until it bursts, releasing the sporozoites into the body cavity of the mosquito to be passed on to humans.
