The relationship of ABO blood groups to bacteremia.

Abstract

ABO blood types of patients with positive blood cultures were compared with those of patients with negative blood cultures and blood bank work-ups. The proportion of blood types in patients with positive blood cultures and blood bank work-ups was very similar. However the proportion of patients with negative blood cultures, though statistically insignificant, appeared to be different. Also, proportions of blood types of patients having Staphylococcus aureus bacteremia suggest that patients with type A blood may be slightly more prone to S. aureus bacteremia than those of other types. Results show that there is no apparent statistically significant correlation between blood group type and the occurrence of bacteremia in the small population studied; however, a more exhaustive study might find otherwise.
