The regulatory role of the spleen over macrophage activation in mice was investigated. The macrophage migration inhibition test was used to measure in vitro macrophage activity. Macrophages from splenectomized, infected mice were shown to have increased migration and therefore increased activation over macrophages from normal infected mice. The effect of plasma from Listeria infected mice on splenectomized mice was tested. It was shown that immune plasma had no effect on macrophage migration. Results indicate the macrophage is responsible for increased resistance to Listeria infection in the splenectomized mouse.
