Transfusions of Red Cells in Malaria

Abstract
Summary The course of the parasitemia in ducks infected with P. lophurae is changed by the injection of duck blood. The parasitemia may be kept at a high level by the injection of large amounts of duck blood. Transfusions apparently have little if any effect upon the ultimate outcome of P. lophurae infection in ducks. The relationship of transfusions to the course of parasitemia and to the mechanism of immunity in P. lophurae infection in ducks is discussed.
