| MICROBE | An organism which can only be seen under a microscope |
| PATHOGEN | A Disease causing microbe |
| VIRUS | DNA surrounded by a protein coat. Not really alive as they need other cells to reproduce |
| BACTERIA | A single celled microbe with a cell wall an no nucleus |
| FUNGI | Microbes that live on dead organic matter and feed by extra-cellular digestion |
| ANTIGEN | A protein marker found on the outside of microbe cells |
| ANTIBODY | A protein made by white blood cells which attaches to specific antigens and allows the body to recognise and destroy pathogens |
| TOXIN | Poisonous chemical released by microbes that make you feel sick |
| VACCINE | Dead microbes that allows the body to develop immunity to a disease |
| IMMUNE | Once your white blood cells have recognised a microbe, they are able to prevent you getting sick by producing antibodies rapidly. Can be natural or acquired. |
| ANTIBIOTIC | A chemical that destroys bacterial cells, but does not harm human cells (e.g. Pennicillin) |
| ANTIBIOTIC RESISTANCE | Bacteria are able to develop resistance to antibiotics that have been used for a long time, making the antibiotic less effective at killing the bacteria. |
