2. Antibiotic Resistance
Biology I

3. Antibiotic Resistance
Antibiotic – medicine made to fight bacterial infections.
Antibacterial – commercial substances made to kill harmful bacteria.
Antibiotic Resistance – the ability of a microorganism to withstand the effects of antibiotics and antibacterial substances.
Bacteria that are resistant to multiple antibiotics/antibacterial substances are superbugs.

4. Antibiotic Resistance
How does it work?
Weak bacteria get killed off when exposed to antibiotics or antibacterial substances.
Stronger bacteria survive longer.
If not exposed to antibiotics or antibacterial substances for long enough, the stronger bacteria will stay alive.
These stronger bacteria then reproduce and/or share their genes via conjugation.

6. Antibiotic Resistance
Antibiotic resistance occurs in two ways:
Naturally through evolution (changing over time).
As the result of environmental pressures (increased exposure to antibiotics and antibacterial substances).

8. Antibiotic Resistance
Examples of Resistant Bacteria:
Staph Infections –Staphylococcus aureus
The first antibiotic resistant bacteria – found to be resistant to penicillin just four years after its development
Treated with methicillin and oxacillin
MRSA – Methicllin-resistant Staphylococcus aureus
Pencillin-Resistant Pneumonia – Streptococcus pneumoniae
Tuberculosis – Mycobacterium tuberculosis
Salmonella
Gonorrhea
