Malaria is caused by a digenetic and triphasic protozoan parasite known as Plasmodium .Four species of Plasmodium cause malaria in human beings.
They are Plasmodium vivax, plasmodium malariae , plasmodium falciparum and plasmodium ovale .

The infective stage of parasite in human beings is Sporozoite .

The vector is female mosquito of genus Anopheles which introduces the parasite in human beings during blood sucking incubation period is 10 – 15 days for plasmodium ovale and plasmodium vivax 6-12 days for plasmodium falciparum and 28 – 30 days for plasmodium malariae.

Life cycle of plasmodium has three phases : schizogony, gamogony and sporogony.
