|Disease||Parasitic disease, Amoeba|
|Blood Group Link||Though one study showed than Amoeba did not seem to adhere to the red blood cells of any particular blood type over another (1,2) a separate study showed that the percentage of Amoeba phagocytosed (scavenged) by the immune system was higher if the Amoebas were attached to type A or AB red blood cells versus type O or B. (3) Thus, though no particular blood type seemed to contract Amoeba over the others, types A and Ab seem to mount a better immune response to it. This may explain why Amoebic infection was seen to be associated with type B blood in one study.|
A study has been performed on 467 cases of differents parasitic diseases and ABO blood groups. With classical statistical methods, we did not find any correlation, but with a large number of variables, we used the factorial analysis, and we obtained maps with relationship O-hookworm and strongloidiasis. A-giardiasis, B-Entamoeba coli. (4)
