In certain Sporozoa, a small active, usually elongate, sickle-shaped or somewhat amœboid spore, esp. one of those produced by division of the passive spores into which the zygote divides. The sporozoites reproduce asexually.
the motile stage of Cryptosporidium which is released after excystation.
one of the minute active bodies into which sporozoans divide in one stage of their life cycle
A stage in the life cycle of the malaria parasite. Sporozoites are produced in the mosquito and migrate to the mosquito's salivary glands. They can be inoculated into a human host when the mosquito takes a blood meal on the human. In the human, the sporozoites enter liver cells where they develop into the next stage of the malaria parasite life cycle (the liver stage or exo-erythrocytic stage).
motile, elongated, infective stage of sporogony
The infectious form of the malaria parasite, which is injected into people by a feeding mosquito; a spore formed after fertilization; any of the elongated, nucleated cells by division of he encysted zygote of a sporozoon, which undergo multiple fission to give rise to merozoites.
One stage of the Plasmodium life cycle. Sporozoites are formed in the mosquito and are transferred to the host where they move to the liver cells.
the infective stage of the malaria parasite that is passed to the human host from the salivary glands of the mosquito. Sporozoites infect liver cells, disappearing from bloodstream within 30 minutes. The mechanism for this amazingly rapid disappearance from the bloodstream to the liver is still unknown. Sporozoites are delicate and spindle-shaped stages that are released into the haemocoel of the mosquito when the oocyst ruptures. Some eventually find their way to the salivary glands of the mosquito.
In the life-cycle of apicomplexan protozoa, sporozoites are cells that infect new hosts. In the parasites that cause malaria (Plasmodium), for instance, the sporozoites are cells that develop in the mosquito's salivary glands, leave the mosquito during a blood meal, and enter the liver where they multiply. Cells infected with sporozoites eventually burst, releasing merozoites into the bloodstream.
