Antibiotics
Medicine made by microbes, to kill microbes.
Match each antibiotic or term to the fact about it.

Free play — tap an item on the left, then its partner on the right; each link tells you why. Switch to when you're ready to test yourself.
Note where each drug comes from: penicillin from a fungus, streptomycin from a bacterium.
What this lesson covers
Challenges to clear
- Match every item.
- Connect antibiotic resistance to how bacteria come to have it.
The task
Match each antibiotic or term to the fact about it.
What this lesson covers
- Penicillin — The first antibiotic, obtained from the mould Penicillium notatum (Fleming noticed in 1928 that bacteria would not grow near the mould.)
- Alexander Fleming — Discovered penicillin by accident on a contaminated culture plate (He noticed a clear ring around the mould where bacteria had died.)
- Streptomycin — From Streptomyces; used against tuberculosis (It came from a soil bacterium, not a fungus.)
- Tetracycline — A broad-spectrum antibiotic effective against many kinds of bacteria (Broad-spectrum means it does not target one group only.)
- Antibiotic — A substance produced by one micro-organism that kills or stops another (Anti = against, bios = life — but only microbial life.)
- Antibiotic resistance — Bacteria surviving a drug because the course was left unfinished or overused (The survivors multiply, and the drug stops working for everyone.)
- Why antibiotics fail against a cold — Colds are viral, and antibiotics act only on bacteria (A virus has no cell wall or bacterial machinery for the drug to attack.)
Hint
Note where each drug comes from: penicillin from a fungus, streptomycin from a bacterium.
