[Comparison of the survival of desialylated erythrocytes and demonstration of the presence of T-agglutinin in rabbits and ducks].

Rabbit as well duck erythrocytes desialization leads to a dramatic decrease of their survival time. Rabbit erythrocytes are trapped transiently by the liver ; in contrast splenic uptake is gradual. Serum from the two species contains a T-agglutinin directed against autologous desialyated erythrocytes. In the two cases, this T-agglutinin is from the IgM class and its immunodominant sugar is galactose in the beta configuration.
