Protective effects of human milk in experimental staphylococcus infection.

Mice were given human milk and sublethal doses of virulent Staphylococcus aureus subcutaneously on 7 to 14 consecutive days. When mice of this group and mice of control groups were later challenged through intraperitoneal injection of a lethal dose of the same Staphylococcus aureus, the death rate for the experimental group was found to be much lower than the death rate for the controls.
