| bacteriology | The study of bacteria |
| inoculate | Implanting a disease agent into a person or animal to produce a disease and stimulate resistance |
| culture | To grow bacteria on a food supply |
| petri dish | A clear round dish with a lid used to grow bacteria |
| inoculating loop | Instrument used to move bacteria so we don't have to touch it |
| agar | Food that bacteria grows on. |
| bacteria | Prokaryotes that are unicellular microorganisms belonging to the domain bacteria |
| bacterium | Singular form of bacteria |
| colony | Many bacteria living together |
| pathogenic | Disease causing bacteria that make you sick |
| incubator | Machine used to warm organisms or grow bacteria |
| incubation | Period of time from exposure to bacteria until you get sick |
