Abstract

The effect of mouse interferon on the bactericidal activity of macrophages against pyogenic cocci was examined. Mouse peritoneal macrophages were cultivated with Staphylococcus aureus in vitro and viable Staphylococcus was recovered by treatment of the mixed macrophage-bacteria culture with sodium dodecyl sulphate (SDS) solution. Results showed that S. aureus was phagocytized and killed by the macrophages. Mouse L cell interferon enhanced the bactericidal activity of macrophages. A mouse brain interferon preparation also enhanced this activity. However, heat-inactivated L cell interferon and heterologous rabbit RK-13 cell interferon and human leukocyte interferon did not enhance it. This suggests that interferon enhances the bactericidal activity of macrophages against S. aureus.
