what are some of the strengths and weaknesses to using a Culture dependent enumeration approach from a microbial perspective

Describe what is involved in direct specimen testing, presumptiveand confirmatory tests, cultivating and isolating the pathogen, biochemicaltesting, and gene probes.

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 a procedure you could do, involving making a slide of the organism?

What is the difference between in-situ & ex-situ conservation?

What is the independent variable? What is the dependent variable? Suggest a control for this experiment?

Which of the following is NOT correctly matched?   A. Halophile – microbe that can grow in an environment with high osmotic pressure (e.g., salt) B. None of the other four answers (all are correctly matched) C. Agar – complex polysaccharide from seaweed used as a solidifying agent in culture media D. Colony – a population of microbial cells arising from a single cell or spore or from a group of attached cells E. Capnophile – microbe requiring an elevated molecular oxygen (O2) environment for optimal growth

A colleague is struggling understanding how bacteria can be beneficial to humans. Please discuss two ways how this is possible and provide valid support with examples.

What is an example of a routine procedure performed by surgical technologists prior to entering the sterile field that would be part of the aseptic technique?

What are the advantages and disadvantage of using spectrophotometry and CFU counting to estimate bacterial growth

What are bioreactors ? How are large volume of culture maintained and processed in them ?
