Hi Melissa,
Antibiotics work to kill bacteria. Bacteria are single-cell organisms. If bacteria make it past our immune systems and start reproducing inside our bodies, they cause an infection or diseases. All cells reproduce. An antibiotic is a selective poison. It has been chosen so that it will kill the desired bacteria, but not the cells in your body. Each different type of antibiotic affects different bacteria. Antibiotics cause bacteria to die instead of reproducing. Hope this explains things for you.
