Oocyst plasmodium
WebOocysts take 1–5 days to sporulate in the environment and become infective. Intermediate hosts in nature (including birds and rodents) become infected after ingesting soil, water or plant material contaminated with oocysts . Oocysts transform into … Weboocyst, a thick-walled structure that forms under the mosquito's outer gut lining. The oocyst undergos asexual replication, called sporogony, which culminates in the production of several thousand sporozoites. Upon maturation the oocyst ruptures and releases the sporozoites into the hemocoel of the mosquito.
