The effect of cortisone on Plasmodium berghei infections

Abstract

Cortisone appears to enhance the production of some humoral agent in the serum of infected mice which, when injected in extremely small quantities into experimental, infected animals, produces a decrease in the parasitaemia in the peripheral blood. This effect is not produced by clean serum, and only slightly, if at all, by the serum from infected mice which have received no cortisone.
