There are many different conditions in which are needed for the growth of micro-organisms. For example, micro-organisms main source of growth is food, especially meat or protein such as fish or poultry. In order for the micro-organisms to grow at a faster rate is to find warmth. Identify the differences between bacteria, viruses, fungi and parasites
Bacteria are very small singular organisms that can be found anywhere in the world.
Viruses are a coated genetic material in which is takes over the cells in our body and then starts a reproduction process. Which means the virus will multiply very quickly.
Fungi are a multi-celled living organism.
Parasites are different types of living plants and also animals which then benefit from using the plants and animals through their metabolism.

Describe what is meant by ‘infection’ and ‘colonisation’
Infections are an invasion of body tissues which are from a disease. This is then called microorganism.
