Impact of Existing Diseases on Subsequent Infections
- Give a clear account of a pathogen as a disease-causing organism, covering viruses, bacteria, fungi and protists.
Pathogens: Types and Disease Mechanisms
- Give a clear account of some common infections, covering: a cholera (bacteria) causes diarrhoea b tuberculosis (bacteria) causes lung damage c Chalara ash dieback (fungi) causes leaf loss and bark lesions d malaria (protists) causes damage to blood and liver e HIV (virus) destroys white blood cells, leading to the onset of AIDS fB stomach ulcers resulting from Helicobacter (bacteria) gB Ebola (virus) causes haemorrhagic fever.
Common Infectious Diseases
- Build an explanation of the way pathogens are spread and how this spread may be reduced or prevented, covering: a cholera (bacteria) – water b tuberculosis (bacteria) – airborne c Chalara ash dieback (fungi) – airborne d malaria (protists) – animal vectors eB stomach ulcers resulting from Helicobacter (bacteria) – oral transmission fB Ebola (virus) – body fluids.
