M3A3: Essay: Diagnosis of an Infected Patient
In this essay, you are asked to demonstrate your understanding of the different types of culturing and staining procedures discussed in Chapters 3 and 7. You will have TWO WEEKS to research and compose your essay.
Consider the following scenario:
You are given a sputum sample from a patient that may be infected with bacteria from one of the following genera:
1. Bacillus
2. Escherichia
3. Mycobacteria
For this essay,
• Describe the handing of the specimen and how the infectious agent, in this case a bacterial pathogen, is isolated from the sputum sample.
• Explain techniques used to isolate bacteria from a clinical specimen using the LearnSmart laboratory exercise, “Isolation Methods” as well as Chapter 7 to support your account.
• Discuss how staining techniques may be applied in the identification of an unknown sample.
• Discuss each staining protocol. Mention the steps involved and how each step and each protocol would identify or eliminate each of these genera as a suspect. You may refer to other scientific resources, but they should be in addition to and not in place of the module resources.
• Describe the important anatomical differences among these three genera and the staining protocols you would use to identify which genus is causing the patient’s infection.
Your essay should be approximately 2 pages in length, double-spaced in 10-12 point font. Please be sure to cite all sources of information, including the text book, in the essay text and on a reference page using APA format. When you have finished your essay, attach it to the assignment drop box and submit it to your instructor.
