This is a very general question to which I cannot give a useful answer other than to say that "antibiotics" are the class of medications that are used to kill bacterial infections.

Not all bacteria are bad. The human digestive system makes extensive use of "good" bacteria to digest food, and imbalance in this bacterial system can cause stomach upset and digestive problems. "Good" bacterial flora are "probiotics", and include the live acidophilus culture in yogurt.
