Causes of Maleria by Mosquito Bites and other causes

Causes of Maleria

Protozoan parasites which are of the genus Plasmodium causes Maleria. In human beings, P.falciparum, P.malariae, P.ovale and P.vivax causes Meleria. Eighty percent of infections and ninety percent of deaths are caused by P. falciparum. Birds, reptiles, monkeys, chimpanzees and rodents get infected by parasitic Plasmodium species.

Plasmodium falciparum

It is a protozoan parasite of the Plasmodium species which are transmitted by Anopheles mosquitoes. This is the most dangerous of the infections as they have the highest rate of complications and mortality.

Plasmodium malariae

This is also a parasitic protozoa that causes Maleria in humans and dogs. It is not as dangerous as P.falciparum and P.vivax. This causes recurring fever in the infected person. More large grains of malarial pigment are seen in these parasites when compared to other Plasmodium species.

Plasmodium Ovale

Tertian Maleria is caused in human beings by plasmodium ovale which is a species of parasitic protozoa. It is less dangerous than P.falciparum and is rare compared to P.falciparum and P.vivax.

Plasmodium vivax

It is one of the four species of parasite that cause Maleria in human beings. This parasite is the cause of the most frequently and widely distributed benign Maleria. The attacks of Plasmodium vivax is minor than Plasmodium falciparum. As Anopheles mosquitoes are the only gender in mosquitoes that bite, they pass on this parasite.

When the parasites enter the bloodstream, they travel to the liver and multiply there. Then they travel back from the liver to the blood where they grow and multiply quickly and clog blood vessels and rupture blood cells. When the blood cells rupture, they attack other red blood cells. Maleria is not contagious.
