Summary: The purpose is to explain roles of host, bacteria, and antibiotic and to emphasize their interrelationships during infection. There is a detailed description of the body's natural defenses against infection. When that fails, antibiotics may be needed. There are basically three ways in which antibiotics work. One interferes with the bacterial cell's wall. Another attacks the bacterial cell's membrane. And the third interferes with the bacterial cell's protein.
