How does antibiotic resistance occur?

Bacteria can mutate and this mutation can make them resistant to an antibiotic. Treating this infection then means that only the non-resistant strains of bacteria will be killed. The resistant bacteria will be able to survive and reproduce so the population of the resistant strain increases. The over-prescribing of antibiotics has contributed to the increased development of these resistant strains.
