|
|
Term
|
Definition
| Conducted a heated air experiment to prove biogenesis (1837) |
|
|
Term
|
Definition
| Ultimately discredited abiogenesis (1860s). Considered one of the "fathers" of microbiology. Also explored relationships between microbes and food, connected specific microbes to specific diseases, and advanced vaccination. |
|
|
Term
|
Definition
| Showed some microbes require intense heat and pressure to kill |
|
|
Term
|
Definition
| Discovered bacterial spores |
|
|
Term

Definition
| Potentially fatal and dangerous disease that colonizes the genital tract after childbirth. Was abundant in hospitals through the 1800s because of poor hygiene among doctors. |

|
|
Term
|
Definition
| Heating to a specific temperature for a set time to kill bacteria |
|
|
Term
|
Definition
| Developed criteria for determining whether a given microbe causes a given disease |
|
|
Term
| Sometimes Koch's postulates don't work. Why? |
|
Definition
| Usually, it's because the pathogen can't be grown in culture. Some microbes are very picky about their environment, and we can't replicate those conditions accurately enough to grow them in lab. |
|
|
Term
|
Definition
| Showed that some bacteria have beneficial roles (1888) |
|
|
Term
|
Definition
| Studied tobacco mosaic virus (1890s). Couldn't identify the causative agent, so assumed it was poison. |
|
|
Term
|
Definition
| Studied tobacco mosaic virus, and found that the agent could not be diluted (and thus not a poison), and was only active on tobacco leaves. Coined the term "virus" (1895) |
|
|
Term
|
Definition
| Discoverer of a virus causative of chicken leukemia (1911). Later won a Nobel Prize. |
|
|
Term
|
Definition
| Self-replicating, misfolded proteins. Diseases caused by these are called transmissible spongiform encephelopathies (TSE). |
|
|
Term
|
Definition
| The scientific technique of classifying objects |
|
|
Term
|
Definition
| Based on physical characteristics. Easy to use, but misleading. |
|
|
Term
|
Definition
| Based on how organisms are related through evolution. Very new and clashes with traditional taxonomy, but more accurate. |
|
|
Term
|
Definition
| Botanist/physician who came up with the first classification system for life (1735) |
