1. Antibiotics are used to kill off bacteria.
Antibiotics are used when you have a bacterial infection.
They are a chemical which can help your immune system fight and kill the bad bacteria.
It can also slow the growth of that bacteria.
This will help you recover quickly.
2. Penicillin was the first antibiotic to be found!
There are lots of antibiotics around today.
However, penicillin was the first antibiotic to be found.
In fact, the scientific discovery was made in England, in 1928.
3. Alexander Fleming was the man who discovered penicillin.
Alexander Fleming was a scientist from the UK. He was working in St. Mary’s Hospital in London, in the year 1928.
One day he discovered the first antibiotic, penicillin.
He had some bacteria called ‘Staphylococcus aureus’ which he put on a petri dish. Alexander Fleming then realised that this bacteria had been killed by mould which was growing on the petri dish.
He realised it could dissolve bacteria! This is what he named penicillin.
He called it this because the type of mould was called Penicillium.
4. Sometimes it’s better to let your body fight for itself!
Everyone has an immune system.
Your immune system is there to fight off any bacteria or viruses that are attacking your body.
Sometimes it is best to let your body get rid of illnesses naturally.
Your immune system will build up antibodies and will become stronger.
5. We shouldn’t use antibiotics too much otherwise the bacteria will become resistant!
Antibiotic resistance is becoming a big problem.
Sometimes we might rely on antibiotics too much and use them when we don’t need them.
Doing this too much can make bacteria resistant to them, so when you really do need them they might not work.
The NHS has tried to stop giving them out for things like sore throats, chest infections and ear infections as your body is usually able to do the work for you.
6. You should always finish the antibiotics the doctor gives you.
You should never stop taking a course of antibiotics half way through.
Always make sure you finish them.
The reason for this is because antibiotics kill bacteria slowly, so even if you start to feel better, there might still be some bacteria left.
If you stop taking the antibiotics early, then the bacteria that is left might start to multiply and you will become ill again.
7. Antibiotics can come in lots of different forms.
Antibiotics don’t just come in pill form. There are multiple ways you can take them.
You can take them from tablets, capsules, liquid (that you drink), creams, sprays, drops, lotions, injections and a drip that goes directly into the blood.
8. There are over 100 different types of antibiotics!
There are hundreds of different antibiotics.
This is lucky as we can use different ones to target different health problems.
Also, different antibiotics can do the same job. This is useful when someone is allergic to one antibiotic, so they can just use another one instead.
9. There are 6 main groups of antibiotics.
Although there are hundreds of antibiotics, they can all be put into 6 different groups.
These groups are:
- Penicillins – These are used to treat infections such as skin infections, urinary tract infections and chest infections.
- Cephalosporins – They are known to be great for treating serious infections like meningitis and septicaemia.
- Aminoglycosides – They are used in hospital but only for very serious illnesses such as septicaemia. They can cause some bad side effects which is why they are only used in hospitals mainly.
- Tetracyclines – This type of antibiotic is very useful when it comes to skin conditions such as acne and rosacea.
- Macrolides – These work well for chest and lung infections. They are also very useful for people who might be allergic to penicillin.
- Fluoroquinolones – These antibiotics were used a lot in the past and helped with a large range of infections. However, because of the bad side effects they aren’t used that much anymore.
10. In Ancient Egypt they used to put mouldy bread on their wounds.
In Ancient Egypt, people would put mouldy bread on their wounds.
With the research behind how antibiotics work, it is easy to see how this method was useful in the ancient times.
The mould in the bread helped them to heal quickly.
Although it wasn’t an antibiotic, it still used some of the science behind them that we use today.
