Communicable diseases are diseases caused by pathogens such as bacteria and viruses. In this topic, you will study the ways in which diseases can be transmitted between animals and plants. You will also study several different diseases caused by different pathogens and look at the ways in which our bodies combat infection. Set 1 will also study how bacteria are grown in the lab and diseases in plants.
