Lesson details
Key learning points
- Some, but not all, bacteria are pathogens that can cause communicable diseases in humans.
- Pathogenic bacteria produce toxins that damage living tissue and cause disease.
- Cholera, TB and Helicobacter stomach ulcers as example; how they are spread, and how the spread can be reduced.
- Viruses invade cells to reproduce where they cause damage to cells.
- Ebola as an example of a viral disease; how it is spread, and how the spread can be reduced.
Keywords
Bacteria - single celled prokaryotes
Pathogen - a microorganism that causes disease
Communicable disease - a disease that can be spread from one organism to another
Toxin - a poison made by bacteria
Virus - an infectious agent
Common misconception
Pupils may believe that viruses are alive.
Viruses are not cells. They do not carry out many of the processes of living organisms such as replication and respiration.
