N INCREASED SUSCEPTIBILITY to infections in leukemia and in primary malignant disorders of the reticuloendothelial system. especially in some forms, is generally admitted. The nature of the defects in host resistance to bacterial infections in these diseases has not been clearly defined. One possible cause which has been considered is a decrease in the ability to form circulating antibodies. In...
