1. ANTIBIOTICS
AND SUPERBUGS

2. Antibiotics can treat bacterial infections
Antibiotics are substances that can either kill bacteria or prevent them from growing.
Only work against bacteria, not viruses or other microbes.
Example: Penicillin is a common antibiotic

3. Penicillin
By accident in 1928, a British scientist named Alexander Fleming returned to his laboratory from holiday to find several petri dishes with Staphylococcus aureus bacteria still on his bench.
One dish also had a large patch of mould growing on it. No bacteria were growing around the mould.
Derivatives: erythromycin, amoxicillin and tetracycline

4. Superbugs
Super bugs are bacteria that have become resistant to several types of antibiotics. .
Eg Methicillin-resistant Staphylococcus aureus (MRSA).
Some disease such as tuberculosis, pneumonia and meningitis are now more difficult to treat as a result of antibiotic-resistant bacteria

5. What causes antibiotic resistance?
