Communicable Disease - Protists
Biology: AQA GCSE Higher, topic 3.1.8
Protists
Protists are single-celled eukaryotic organisms (they have a nucleus). Lots of protists are parasites. This means that they live on or inside other organisms. They are often transferred to the host organism by a vector, such as an insect or mosquito. An example of a disease caused by a protist is:
Malaria
- Malaria is spread by the female anopheles mosquito (a vector).
- If a mosquito is carrying malaria, then it transfers the infection into a person’s bloodstream when it bites them.
- Malaria leads to recurring and severe fevers, which can cause death.
