Understand how resistance to antibiotics can increase in bacterial populations
Case Study:
Bacteria Staphylococcus aureus can cause skin or lung infection.
The antibiotic can kill the Staphylococcus aureus. The ones that are killed are susceptible, called MSSA.
When random mutation occurred to the genome of the bacteria. When the antibiotic is applied, the bacteria did not die. This is given the name resistant, creating a new type of bacteria known as MRSA.
As a result, mutation has created genes that allow bacteria to break down the antibiotic, resisting it and survived. This form of the bacteria increasingly survives and becomes more common.
This can become serious problem in hospitals and treatment.
