The drugs are first tested in labs where they use cells to see how strong the drug is. The drug is then tested on live animals to find its toxicity and effectiveness, this test also gives an indication on the optimum dosage required. Clinical trails involve testing the drug on healthy patients first, they are given the drug to see possible side effects and also to find out how safe they are on humans. The number of Volunteers is increased to see if there are possible problems with the drug on patients with different body factors. They are finally tested on people with the illness where they try and find the optimum dosage.
Additional notes: Double-blind trails are when the doctor and the patient don't know who is taking placebo and who is taking the actual drug.
Explain how MRSA has become resistant to some types of antibiotics (4/5 marker ?)

Steps in drug trialling: Firstly, the drug is discovered (not sure if optional). Then lab research is done on it. Next, it is tested on animals, then cells/ tissues, then on human volunteers. Penultimately the drug is evaluated by researchers before it is finally sold to doctors.

MRSA has become resistant to some types of antibiotic due to natural selection. There is variation in the bacterium population, a mutation may lead to resistance to antibiotics. Those with resistance are better adapted to their environment and they survive, and they pass on their beneficial gene, whereas those without the beneficial gene die. Over time an entire population of antibiotic resistant bacteria will be found.

the pathogen is inserted into the blood stream
the white blood cells react by producing antibodies which target these pathogens and kill them
when the pathogen gets into the body again the white blood cells can respond quickly by producing antibodies to kill the pathogen
