Summary Introduction
To enlist:
Koch’s postulates and also discuss when they may not be appropriate in establishing causation.
Concept introduction:
Robert Koch was a German bacteriologist and physician. In the 1890s set out criteria for determining whether bacteria are an agent of a particular disease. He established criteria to discover a “causative relationship” between a bacterium and a disease. Koch postulates are used to identify the cause-and-effect relationship between bacteria and particular clinical disease.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
