Chapter 17.2, Problem 3R
Summary Introduction
To review:
The use of metagenomics to develop microbial fingerprint of bacterial species isolated from the skin of human belly button.
Introduction:
Metagenomics is the study and identification of different species of microorganisms by directly isolating deoxyribonucleic acid (DNA) from any given environment. The traditional method uses different culture methods to identify specific microbes based on the appearance of colonies and culture media used.

You have learned many different techniques so far this semester that allow us to identify pathogenic microbes in the clinical setting. Why do you think rapid methods are so helpful? Why are traditional tests such as metabolic tests not always used to ID clinically important microbes?
You are hired in one of the microbiology labs in Memphis and your first assignment to identify microbial samples from a local restaurant. You are given a set of slides and asked to classify the specimens as Gram positive or Gram negative.
6) What would be the last reagent you use to identify the bacteria? 7) What type of visual aid you need to help you see the bacterial samples clearly? 8) After the use of what reagent, you will be able to decide if you have a Gram positive or Gram negative bacteria?

- You mixed up the numbers on the tubes when you inoculated the mannitol salt agar (MSA) plate. You do not know if you grew staph epidermis or E. coli. You found that the organism growing on the mannitol salt agar remained red after incubation.

Have your lab partner write a critique of your isolation technique in the space below. The following should be addressed: was isolation produced on one or both plates? On the quadrant streak, we're the first three streaks near the edges of the plate? On both plates, did any streaks intersect streaks they should not have? Was the whole surface of the agar used?
