Term
a primary immune response resulting from transfusion of blood from genetically different individuals is dangerous to the recipient only if
Definition

the transfusion is repeated

in a secondary exposure, the recipient already possesses some antibodies and produces more antibodies very rapidly. This immune response will destroy the transfused cells and in the process may cause damage to the recipients tissues.

this is called a transfusion reaction, a form of tissue graft rejection.

Term

Definition
  • can occur in a second pregancy of Rh positive fetus in a Rh negative mother.
  • during first pregancy of Rh + fetus, mother is exposed to fetal blood and develps antibodies
  • During 2nd pregancy, the mother's blood contains antibodies which attack the fetal red blood cells.
  • if the fetus survives, it can be born with e. fetalis, in hwich destruction of mature red cells causes a form of hemolytic anemia marked by appearance of immature, nucleated red cells in the newborn's blood.
  • erythroblastosis fetalis can be prevented by administration of Rhogam, with is a preparation of antiRh antibodies to Rh negative mothers at the time of each delivery.
  • the Rhogam binds with an Rh antigen that has entered the mother's bloodstream, preventing it from triggering a primary immune resonse.
