Microorganisms are living things so small that we often need a hand lens or microscope to see them. They include bacteria, fungi, single-celled plants, single-celled animals, and viruses. Microorganisms are all around us, in the air we breathe, in the food we eat, on our skin and inside our bodies.
In this podcast, Sian looks at ways microorganisms are helpful to us, and at ways microorganisms cause problems for us.
