Definition of an Antibiotic Antibiotics are medicine used by doctors when microbes have made you sick. Some antibiotics stop the bacteria multiplying but others can stop the bacteria entirely.

Who discovered Antibiotics? In 1928, Professor Alexander Fleming “accidently” discovered Penicillin while working at St Mary’s Hospital in London

How were Antibiotics discovered? One day Alexander Fleming was growing bacteria in a pi tri disk. But he left one of the plates open by accident and a mould started growing on the top. Alexander Fleming noticed that the mould stopped the bacteria from spreading. The mould stopped the bacteria from spreading, and it was killing the bacteria. This mould was called “ Penicillium Notatum”.

Why was it important at that time that they were discovered? It was important at the time for the antibiotics to be discovered because there was a lot of diseases and sickness going around at that time that were very serious and deadly. So it was important for them at that time for the antibiotics to kill the bacteria and stop it from spreading and getting worse.

How are Antibiotics produced in large amounts?

Are there any problems with using Antibiotics? Yes, antibiotics can cause a problem because if they aren’t tested they can make a major change like deformation in kids or they could even kill you. Also sometimes antibiotics stop working and not function they way they are meant to.

What does it mean to be resistant to Antibiotics? Some bacteria produces “enzymes” which break down and stop antibiotics, so they can still grow in its place. These are said to be resistant strains to these antibiotics.
