Blood type and malaria

Blood type and malaria

Blood type can have a direct link with malaria –a disease transmitted by mosquitos that affects the blood.

It has been found that those with the blood type O seem to have some form of protection from the most dangerous strand of malaria known as Plasmodium falciparum, as opposed to its less dangerous counterpart, Plasmodium.

Amongst other issues, the parasite responsible for the condition causes the red blood cells in the capillaries to clump together, this results in serious damage to the tissues. In order to determine how blood type O has a form of protection against this parasite, a study was conducted by Swedish researchers who examined the protein that is secreted by the parasite responsible for malaria infections. The study found that the parasite seems to bind more effectively to the red blood cells of types AB compared to those of type O.
