Antilymphocyte autoantibody in lethal mouse malaria and its suppression by non-lethal malaria.

abstract：:The in vitro binding serum complement (C) components to Schistosoma mansoni worms was studied. By exposing frozen sections of adult male and female parasites to normal human serum, binding of both classical and alternative pathway C components was observed. By immunofluorescence (IFL) microscopy selective binding of C...
