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?
Explain a simple test one could do to determine if drug resistance isdeveloping in a culture.

The least effective antibiotic has a smaller clear area around the antibiotic disk.
