Students have asked these similar questions
Differentiate between Bergey’s Manual of Systematic Bacteriology and Bergey’s Manual of Determinative Bacteriology.
The techniques for identifying unknown bacteria can be summarized in three key steps, explain in your own words how to:
Staining the unknown for initial characterization by microscopy.
Using a dichotomous key strategy to systematically rule out other organisms.
Testing the organism for key biochemical traits.
Note that it is not appropriate to self-diagnose outside of a medical context and this is a completely hypothetical scenario.
Imagine you have a rash on your foot. You're concerned that it's an infection and inoculate a sample onto an agar plate. You wonder, How can I figure out whether the pathogen is a bacterium vs a eukaryote?
You decide to use lab supplies to get a basic understanding of the pathogen. Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we could do in our lab.
What is one experiment you could do, involving culturing the organism?
