''Plasmodium malariae'' is a parasitic protozoa that causes malaria in humans. It is one of several species of ''Plasmodium'' parasites that infect humans including ''Plasmodium falciparum'' and ''Plasmodium vivax'' which are responsible for most malarial infection. While found worldwide, it is a so-called "benign malaria" and is not nearly as dangerous as that produced by ''P. falciparum'' or ''P. vivax''. It causes fevers that recur at approximately three-day intervals (a ''quartan fever''), longer than the two-day (tertian) intervals of the other malarial parasites, hence its alternate names quartan fever and quartan malaria. ==History== Malaria has been recognized since the Greek and Roman civilizations over 2,000 years ago, with different patterns of fever described by the early Greeks. In 1880, Alphonse Laveran discovered that the causative agent of malaria is a parasite.〔 Detailed work of Golgi in 1886 demonstrated that in some patients there was a relationship between the 72-hour life cycle of the parasite and the chill and fever patterns in the patient.〔 The same observation was found for parasites with 48-hour cycles.〔 Golgi concluded that there must be more than one species of malaria parasite responsible for these different patterns of infection.〔
