The main microorganisms in and on our bodies areprotozoa, algae, fungi, bacteria and viruses. Most microorganisms are beneficial, for example, there are microorganisms in our large intestine that synthesise vitamins and allow them to be absorbed into the bloodstream. However, a tiny minority are pathogens(disease-causing agents). These pathogens, often called germs or bugs, are a threat to all life forms.
