Physicians in Medieval Times
- Physicians trained at university medical schools in Italy or Paris.
- They used urine charts and 'zodiac man' charts.

Discovery of Antibodies and Bacteriology Developments
- Robert Koch identified bacteria causing specific diseases, starting with TB in 1882.
- This new science was called bacteriology.
- Koch and his team identified germs for cholera, typhoid, diphtheria, pneumonia, tetanus, and plague.
- This allowed for the creation of vaccinations to prevent these killer diseases.
- Koch realized antibodies could destroy bacteria and create immunity.
- Each antibody worked on one bacteria.
- Introducing a weakened form of the disease would allow the body to resist the deadly version.
- Koch won a Nobel Prize in 1905.
Key Words
- Vaccination: Injecting a harmless form of a disease to prevent it.
