What is the idea of Robert Koch about linking microbes to diseases in 1870-1880?
- Microbes cause specific disease * Identifies TB * Used Scientific method show “cause and effect”
Explain Koch’s Postulates.
- Organism is present in all cases. 2. Isolate that organism, grow it pure 3. Inoculum (pure bacteria) causes the same disease. 4. Reisolate microbe.
