Further Search for Interaction Antigens on Erythrocytes in Selected Species Hybrids of Birds

Abstract

Replicated blood typing reagents were made to detect an interaction antigen (hybrid substance) on the red cells of several species hybrids of birds. Reagents against pigeon X ringneck dove hybrids are compared with other reagents made in an effort to find a similar interaction in the chicken X guinea fowl hybrid and in the ringneck X mourning dove hybrid. Mallard X muscovy hybrids also were tested for their reported red cell interaction product. Both rabbits and parental types were injected with the hybrids' red cells from the chicken X guinea fowl and mallard X muscovy crosses, but no interaction product was disclosed. The single reagent against the ringneck X mourning dove hybrid also failed to detect an interaction product.
