Life cycle of malaria. An Anopheles mosquito bites an infected person, taking blood that contains micro- and macrogametocytes (sexual forms). In the mosquito, sexual multiplication ("sporogony") produces infective sporozoites in the salivary glands. (1) During the mosquito bite, sporozoites are inoculated into the bloodstream of the vertebrate host. Some sporozoites leave the blood and enter the hepatocytes, where they multiply asexually (exoerythrocytic schizogony), and form thousands of u...
