Transmission of Toxoplasmosis by Leukocyte Transfusion

Abstract

Abstract Four patients with acute leukemia developed toxoplasmosis following leukocyte transfusions from donors with chronic myelogenous leukemia. Serologic data, obtained from the donors retrospectively, revealed elevated antitoxoplasma antibody titers, suggesting that the transfused leukocytes were the source of the organism in the recipients.
