Summary Introduction
To explain:
How the treatment of stomach ulcers have changed since the discovery of its causal agent Helicobacter pylori.
Concept introduction:
Antibiotics are chemical agents used to kill or thwart the growth of bacteria. They do so by inhibiting the cell wall formation or disturb the plasma membrane of the bacteria. This makes the bacteria vulnerable and they die.
