You will attach a discussion of your results to the table. Examine the section entitled “Verdicts” (pp. 90-92). How do the results from the study by Shelton et al. differ from the results of the study by Kim, Barak, and Shelton? How do the results of the study by Baskin and Sommers differ from the results of other studies?This is the most important part of your unknown identification project.
This portion of your report is to be typed, double spaced, and submitted by the next lab session. In your discussion, focus on how you identified your unknown based on a process of elimination. The steps for writing your discussion are:
List all possible UTI bacteria used in this laboratory exercise. (5 points)
Discuss your Gram staining results; describe if your Gram staining results allowed you to eliminate any of the possible bacteria as your unknown. (10 points)
Describe the observations and results for lactose fermentation using MacConkey and EMB. Distinguish fermenters from non-fermenters. Based on your results, explain what bacteria can be excluded & included as your UT unknown. (20 points)
Discuss several tests that clearly allowed you to identify your unknown. Give reasons why certain organisms are excluded, and how you reached your specific decision on the identity of your unknown.
Do not include a description of all the tests you performed. Include only the most relevant tests, how they allowed you to eliminate the remaining bacteria that were not previously excluded and determine the identity your unknown. (20 points)
State the unknown number and the identity of the unknown. (10 points)
Conclude your report with a summary statement. (5 points)
