Final answer:
The tests in the dichotomous key to classify enteric bacteria are: Gram staining, Catalase test, Oxidase test, and Indole test.
Step-by-step explanation:
The tests used in the dichotomous key to classify enteric bacteria include:
- Gram staining: This test helps determine the Gram reaction of bacteria, which is a primary criterion for classification.
- Catalase test: This test helps differentiate between bacteria that produce catalase and those that do not.
- Oxidase test: This test helps identify bacteria that possess the enzyme oxidase.
- Indole test: This test is used to detect the production of indole by bacteria.
