Blood type can confer resistance to malaria
Tagged: RSSPosted on: October 29th, 2007
It’s no accident of nature that human blood has split into a handful of distinct types: A, B, AB and O. People with type O blood are at less risk of dying from malaria but more vulnerable to cholera and stomach ulcers, suggesting that different diseases put different pressures on how blood evolved.
Malaria has probably killed more people than any other disease in human history. The malaria parasite invades red blood cells, and some malaria strains then snare other uninfected blood cells, forming “rosettes”.”*
