For this assignment, you will research and describe common testing methods used to identify bacteria in a microbiology lab. Your assignment is to develop a PowerPoint presentation that includes the following:
Slide 1: Title
Title Slide with Name, Course, and Date
Slide 2: Introduction
Topics to be covered in outline form.
Slide 3: Gram Stain
Explain the major differences in the cell wall between a bacterium that stains Gram positive vs. Gram negative. Explain how Gram staining helps distinguish between these types of bacteria. Show a representative image for each stain (briefly describe these images and provide citations).
Slides 4 and 5: Differential Staining
What is the difference between a simple stain and a differential stain? Explain the purpose of a differential stain. Describe an example of one specific type of differential stain (other than the Gram stain) and provide an image (briefly describe the image and provide a citation).
Some examples of differential staining include: acid-fast, capsule, endospore, and flagella.
Slide 6: Growth on Media
Describe the differences between selective and differential media. Research one example from each type of media and explain its purpose. Provide an image of each type of media (briefly describe the image and provide a citation).
Slides 7 and 8: Biochemical Tests
Describe the function of the enzyme catalase and describe a method of testing for catalase activity.
Describe the function of the enzyme oxidase and describe a method of testing for oxidase activity.
Describe a method of testing for coagulase activity and state how to interpret the results (show an example of a positive and/or negative result). Briefly describe the image and provide citations.
Slide 9: Biochemical Tests Continued
Explain the function of one of the following biochemical tests: Rapid Strep A, Latex Agglutination, or Gonocheck test.
Describe an example of a bacterium that would test positive for the test you selected.
Slide 10: Case 1 Bacteria
Using the bacterium you selected in Case 1, summarize the expected results from the catalase, coagulase, and oxidase tests you learned about in the virtual lab exercises. Explain your reasoning.
Slide 11: References
Full list of references in APA format (including citations for any images used)
For this SLP assignment you will develop a PowerPoint presentation that is approximately 11 slides in length and addresses the requirements outlined above. Place the text containing the answers to the questions above in the slide area (not notes), summarizing each topic. All images should be described and explained.
Be sure to include citations referencing your sources. Include a specific title for each slide that describes the topic being discussed. Be sure to include a title slide with your name, assignment type (e.g., SLP Module 1), and course title. Include an introduction slide with the subjects you will cover (in outline form) and a slide summarizing your project findings (Conclusion slide). Your final slide should contain a list of references cited in APA format.
