Antibody responses to xenogeneic red blood cell challenge in the Japanese quail.

Previous reports indicate that Japanese quail are hyporesponsive to such conventionally used antigens as sheep red blood cells and bovine serum albumin. In this study the immune responsiveness of Japanese quail to several erythrocyte antigens was investigated. The quail produced higher antibody titers when immunized with chukar red blood cells than when immunized with sheep, turkey, or pheasant red blood cells. It is concluded that Japanese quail are capable of producing HA titers comparable in magnitude to those demonstrated by other laboratory animals, when the quail are immunized with an appropriate antigen. Chukar red blood cells are such an antigen.
