Infection and Response

Introduction

Infection and response studies the causes, effects, treatments and prevention of diseases. We look at communicable diseases (ones you can catch!) in this topic as you will cover a range of non-communicable diseases (CHD, cancer, diabetes and genetic diseases) in other topics.

There are 7 diseases that you need to be able to be able to describe the causes an d effects of these are:

Bacterial diseases:

  • Salmonella
  • Gonorrhoea

Viral Diseases:

  • Human Immunodeficiency Virus (HIV)
  • Measles
  • Tobacco mosaic virus

Protist Disease:

  • Malaria

Fungal Disease:

  • Rose black spot

PLEASE SEE THE SHEET IN THE ESSENTIALS FOR FURTHER INFORMATION ON THE ABOVE DISEASES

Defence Against Disease:

We take a look at how the body prevents diseases getting into our blood and then how the immune system fights them when they do. We learn that bacteria make us ill by releasing toxins and rapidly multiplying. We learn that viruses make us ill by getting inside of our cells and rapidly multiplying – damaging our cells in turn. As viruses hide inside of cells this means that antibiotics are unaffective against them.

We then finally learn about vaccines and the process of drug development and testing.
