d.maternal transfer of antibody

PASSIVE NATURALLY ACQUIRED IMMUNITY = This occurs when individuals receive antibodies from their mother by a natural process, such as in BREAST MILK or in-utero transfer of antibodies from mother to fetus. In mammals, mother's milk is know to contain a large concentration of antibodies and other antiviral and antibacterial substance that protect the newborn infants. Further, the mother's antibodies cross the placental barrier, particularly near the end of term. In both these circumstances the infant is only resistant to whatever the mother is resistant to.
