Assignment 2 - T1:

2. Explain why you should do the following things and what pathogen you are at risk of.
a. Eat chicken that has not been cooked properly. Do not eat raw chicken it contains a high percentage of salmonella, this bacteria can make you very ill. 
b. Wash your hands regularly with soap and water. Everything you touch is covered with germs, and we regularly touch our face and mouth, be washing our hands regularly, we prevent ourselves getting infected, but also we prevent ourselves getting ill.
c. Never share a towel with someone. Towels contain many germs and dead skin cells, for hygiene reasons it is advised that you do not use the same towel (think of fungi).
d. Let a dog lick your face.
Even though it is very fun, remember that dogs lick their own buts.

a. What sign of the disease is shown in the graph?
b. What symptoms would this patient be experiencing? Name 2.
c. How long was the incubation period? What was the bacteria doing during this time?
d. What caused the fever and how long did it last?

a. What sign of the disease is shown in the graph? temperature

b. What symptoms would this patient be experiencing? Name 2.
1. hot and cold flushes
2. chills


Slide 15 - Slide

Assignment 3 - T2:

4. Look at the graph beside, it shows a patient’s temperature whilst fighting a bacterial infection.
c. How long was the incubation period? What was the bacteria doing during this time?
10 days - they were multiplying till they reached a certain amount that they could make the patient ill
d. What caused the fever and how long did it last?
our immune system fighting the bacteria - 18 days

Assignment 3 - T2:

5. MRSA is a pathogen that has been causing more and more problems in hospitals across the world. 
a. What is MRSA? (don’t just google the letters, explain what it is)
b. How is MRSA treated?
c. What do hospitals do to prevent MRSA spreading?



Slide 17 - Slide

Assignment 3 - T2:

5. MRSA is a pathogen that has been causing more and more problems in hospitals across the world. 
a. What is MRSA? (don’t just google the letters, explain what it is)
This also know as the hospital or flesh eating bacteria, it often attacks patients in hospitals who are recovering from surgery.
b. How is MRSA treated?
Broad spectrum very aggressive antibiotics.
c. What do hospitals do to prevent MRSA spreading?
Wearing protective gowns and using disinfectants wherever they can.

Assignment 4 - I:

6. The following questions are about antibiotics.
a. What is an antibiotic?
b. When were antibiotics first used in the Netherlands?
c. The American army used a lot of antibiotics to treat syphilis amongst the soldiers, unfortunately this created a stronger drug resistant version of syphilis. Explain in detail how this could happen?

Slide 19 - Slide

Assignment 4 - I:

a) A chemical produced by a microorganism which has the ability to inhibit or kill pathogens.
b) Alexander Fleming was growing bacteria on agar plates but left one of the plates open. A mould started to grow on the surface. He noticed that the mould was stopping the bacteria from spreading. It seemed to be making a substance that killed the bacteria. That substance was the antibiotic penicillin.
c) Some of the syphilis pathogens mutated and were able to produce an enzyme that broke down
penicillin. These syphilis pathogens could not be killed by penicillin so they increased in numbers and
the resistance spread.

Assignment 4 - I:

7. Despite the World Health Organisation efforts to expand access to the tuberculosis treatment, multidrug resistant tuberculosis (MDR-TB) remains a major threat. MDR-TB represents a challenge for clinicians and staff operating in national tuberculosis (TB) programmes/centres. In sub-Saharan African countries including Burundi, MDR-TB coexists with high burden of other communicable and non-communicable diseases, creating a complex public health situation which is difficult to address. Tackling this will require targeted public health intervention based on evidence which well defines the at-risk population. In this study, using data from two referral anti-tuberculosis in Burundi, we model the key factors associated with MDR-TB in Burundi.
a. What type of pathogen is MDR-TB?
b. Why is MDR-TB more dangerous than regular TB?
c. Some kids in the Netherlands have been vaccinated and others have not, why is there a difference in this policy?

In this study, using data from two referral anti-tuberculosis in Burundi, we model the key factors associated with MDR-TB in Burundi.
a. What type of pathogen is MDR-TB? It is an aggressive tuberculosis bacteria that is immune to many antibiotics.
b. Why is MDR-TB more dangerous than regular TB? It is MDR (multi-drug resistant) this means many types of antibiotics will not work or help. 
c. Some kids in the Netherlands have been vaccinated and others have not, why is there a difference in this policy? In the Netherlands they only vaccinate if you need it, in this country TB is not a risk, if you travel regularly to areas that are at risk, then your Dutch doctor might choose to vaccinate you.
