Naturally-acquired passive immunity is the transmission of antibodies from mother to the child through colostrum and breast milk. Only one bacteria entered, and there was no immune response producing antibodies. Antibiotics work in different ways to destroy bacterial DNA or deprive bacteria of a food source. Passive immunity results from the acquisition of antibodies from another source and hence memory cells are not developed; Active immunity will result in long-term immunity but passive immunity will not (due to the presence or absence of memory cells) Both active and passive immunity can be induced by either natural or artificial mechanisms Natural passive immunity can also be transferred through breast milk.
