Step by step
Solved in 2 steps
- Koch's postulates include all of the following EXCEPT O 1) Isolate the organism in pure culture. The symptoms of the test animal may vary from the symptoms seen in the O 2) patient. O 3) Inoculate a test animal with the isolated organism. 4) The organism must be isolated from the test animal in pure culture. 5) The organism isolated from the test animal must match the organism isolated from the patient.Explain with the examples of biochemical test that are used to identify the bacteria in the laboratory.Please discuss how the Methyl Red-Vogues Proskauer test helps distinguish microbes from each other.
