Protective Effect of Antilymphocyte Serum on Mice Infected with Plasmodium berghei

Abstract
Rabbit antiserum to mouse lymphocytes prolonged the survival of mice infected with Plasmodium berghei. Since antilymphocyte serum has a well-defined, potent immunosuppressive effect, the immune response of the host to the parasite actually may contribute to the death of the animal with an acute malarial infection.
