Antiseptics are chemical used to attack microbes which might cause

disease!

They stop microbes from multiplying! We use antiseptics to swab wounds or

clean cuts!

Antibiotics are used to control infections. Before they were discovered infectious diseases were

major killers. These do not work on viruses.

Different antibiotics affect bacteria differently.

Bactericides : E.g. penicillin kills bacteria.

Bacteristats: Prevents multiplication.

These substances interfere with the growth of bacteria.

(Antiseptics and antibiotics are antibacterials.)

The term is used more for describing

cleaning products then medicines.

These drugs treat fungal infections. They work because of the differences

between human and fungal cells!

Antifungals target these differences killing the fungal cells only!

There similarities with these cells, this can

cause some side affects!

An agar plate is a sterile Petri dish that contains agar plus nutrients, and is used to grow bacteria or fungi.

Agar plates can contain many different

nutrients. Some can be made out of blood to

grow a particular bacteria.

What are resistant bacteria?

• Over time, bacteria can become resistant to certain antibiotics.

• In a large population of bacteria, there may be some that are not affected by the antibiotic.

• These bacteria survive and reproduce, creating more bacteria that are not affected by the antibiotic.

(b) The researcher placed two small paper discs onto the surface of the jelly.

One disc had been soaked in mouthwash. The other disc had been soaked in water.

The diagrams below show the jelly at the beginning of the experiment and two days later.

Suggest what had happened to the bacteria in the clear area around the paper disc soaked in mouthwash. 1 mark (c) What was the control in this experiment? 1 mark

(d) Give two safety precautions the researcher should take to avoid contact with the bacteria. 2 marks

24 March 2015 Case study - mRSA • MRSA stands for Methicillin

Resistant Staphylococcus. It is sometimes referred to as a ‘superbug’.

• MRSA is a bacteria that has become resistant to antibiotics.

• It was found in most hospitals across the country and was a widespread problem

24 March 2015 What causes resistance?

1) High mutation rates in bacteria lead to different strains.

2) People do not finish the course as they feel better.

3) Some antibiotics sold around the world may be dilute!

4) These drugs are often given to animals and can end up in the

food chain.

5) Prescribed in flu sufferers.

6) Bought over the counter with out medical advice.
