Transfusion-acquired babesiosis can be an asymptomatic or self-limited febrile hemolytic illness in a healthy host. A persistent, relapsing, and/or fulminant course with the development of life-threatening complications may be seen in immunocompromised or splenectomized patients. As in malaria, erythrocyte parasitemia is often associated with nonimmune hemolysis, and can be treated with erythrocytapheresis. Just as warm autoantibodies have been reported in malaria infection, the development of autoantibody-mediated immune hemolysis has been reported in babesiosis. We treated a previously healthy male with multiple injuries from a motor vehicle accident necessitating massive transfusion. Late in the hospitalization, his blood smear revealed Babesia microti, …
