Malaria is the most common cause of hemolytic anemia worldwide, and much has been learned about how the parasite enters the erythrocyte and the mechanism of the development of anemia. Falciparum malaria, in particular, can cause severe and sometimes fatal hemolysis (blackwater fever). The zoonotic malaria parasite Falciparum knowlesi, prevalent in Southeast Asia, is also associated with severe hemolytic anemia. Other organisms cause hemolytic anemia by producing a hemolysin (eg, Clostridium perfringens), by stimulating an immune response (eg, Mycoplasma pneumoniae), by enhancing macrophage recognition and hemophagocytosis, or by as yet unknown mechanisms. The many different infections that have been associated with hemolytic anemia are tabulated and references to the relevant studies provided.
