GERM THEORY

This is the idea or belief that disease are caused by tiny organisms called germs and later called microbes. In the early period, it was believed that diseases were caused by evil spirits or displeasure from gods or peculiar astronomical events. 

KOCHS POSTULATES

1. The microorganism must be present in the diseased animal and not present in the healthy animal.

2. Cultivate the microorganism away from the animal in a pure culture.

3. Symptoms of the disease should appear in the healthy animal after the healthy animal is inoculated with the culture of the microorganism.

4. Isolate the microorganism from the newly infected animal and culture it in the laboratory. The new culture should be the same as the microorganism that was cultivated from the original diseased animal.
