objective 3.33 ; understand how resistance to antibiotics can increase bacterial populations
Bacteria Staphylococcus aureus: causes skin or lung infection.
an antibiotic can kill the Staphylococcus aureus.
The bacteria killed are susceptible, MSSA.
random mutation occurred to the genome of the bacteria.
When antibiotic is applied, the bacteria is not killed
This is resistant, creating a new type of bacteria, MRSA.
mutation has created genes to allow bacteria to break down the antibiotic, allowing it to be able to resist it and survive
This new bacteria increasingly survives and becomes more common.
this resistant bacteria is a problem for hospitals to treat
