Antibiotics, such as penicillin, are drugs developed to cure infections caused by bacteria. Some antibiotics work by destroying the cell wall of the bacteria so that they can't replicate.
Some strains of bacteria are resistant to certain antibiotics. This means that these antibiotics cannot kill them. MRSA is often called a “superbug” because it is resistant to many antibiotics.
How to stop antibiotic resistance?
To help prevent strains of resistant bacteria from developing:
Bacteria can become resistant to antibiotics. This is the process:
In a population of bacteria, a random mutation can arise, which makes that bacteria more resistant to antibiotics. The resistant bacteria reproduce asexually, so the copies will be genetically identical.
