For a 2 micron cell diameter (a relatively large bacterium or a very small eukaryotic cell), the 4 nm thickness implies an aspect ratio of 1:500, similar to the case of an airplane.
Malaria is caused by the protozoan parasite Plasmodium. Human malaria is caused by four different species of Plasmodium: P. falciparum, P. malariae, P. ovale and P. vivax. Humans occasionally become infected with Plasmodium species that normally infect animals, such as P. knowlesi.
Plasmodium falciparum is a protozoan parasite, one of the species of Plasmodium that cause malaria in humans.It is transmitted by the female Anopheles mosquito.f the six malarial parasites, P. falciparum causes the most fatal and medically severe form. Malaria is prevalent in tropical countries with an incidence of 300 million per year and a mortality of 1 to 2 million per year. Roughly 50% of all malarial infections are caused by P. falciparum.
