Micro-organisms, more commonly known as germs, bugs or microbes, are tiny living things too small to be seen with the naked eye. They are found almost everywhere on Earth. Some microbes are useful, and others can be harmful to humans.

Microbes come in many shapes and sizes. The three groups of microbes covered in the resource are viruses, bacteria and fungi.
