[Imported malaria: serological diagnostic and prevention of transfusional malaria (author's transl)]

Some particular aspects, epidemiological, clinical, serological of imported malaria are studied about 137 cases seen in the department of Tropical and Parasitologic Diseases of Cochin Hospital. The interest of studying several antigens, homologous and heterologous, in detection of fluorescent antibodies is discussed. In the case of any infesting Plasmodium species, the use of homologous antigen gives very superior titers. Systematic use of two antigens helps to detect possible antimalaria antibodies in blood donors and prevent transfusion given malaria.
