Fungal and protist diseases in humans

I can describe examples of common fungal and protist diseases in humans, how they are spread, and ways to reduce the spread.

Lesson details

Key learning points

  1. Some, but not all, fungi are pathogens that can cause communicable diseases in humans.
  2. Athlete’s foot as an example of a fungal disease, how it is spread, and how the spread can be reduced.
  3. Protists are eukaryotic microorganisms.
  4. Malaria as an example of a disease caused by a protist, spread by an insect vector, and how the spread can be reduced.
  5. The interaction of sickle-cell trait and malaria as an example of interaction between different types of disease.

Common misconception

Malaria is caused by mosquitos.

Mosquitos are the vector that transfer the protist to humans.

Keywords

  • Fungi - eukaryotic kingdom of microorganisms including yeast and mould

  • Protists - eukaryotic kingdom of microorganisms including amoeba and plasmodium

  • Vector - an organism that carries the pathogen from the host to another organism

  • Allele - a genetic variant in a gene creates an allele (a different version of a gene), which can produce a different phenotype

Another example of a vector is the 'tick'. It transmits a bacteria that causes Lyme disease in humans.
