Case Study on diagnosis for biology

Case Study:

A 22-year-old college student named Mike went to the student health center complaining of yellow discharge from his penis, painful urination and fever. Mike reported that he has recently broken up with his long-term girlfriend and started dating again.  Mike lives in the college dorm with a roommate who is currently ill with Mononucleosis. Lab results indicate the presence of gram-negative diplococcic in the fluid sample taken from Mike’s penis.

Based on the information presented in the case study, answer the following questions in your paper (see guidelines for additional info):

1. What microorganism do you believe is to blame for this illness (be specific)? Provide background information on this organism, history, morphology, virulence factors, toxins, etc…

2. What information from the patient’s symptoms contributed to your decision? Did this information allow you to rule out any other possible culprits? What information from the patient’s history and/or lab samples that contributed to your decision? Support your answers with factual evidence and logical reasoning.

3. What is the epidemiology of this disease? Identify risk factors for this disease and describe the disease course/outcome  in humans.

4. What steps can be taken to treat the illness? How and why are the treatments effective (or ineffective)? Are there any concerns or other complications of this disease?

Project: Case Study Scenario

Addresses Course Outcomes #1, #2, #3

  recognize the use of the scientific method to weigh evidence, make decisions, and solve problems

  apply knowledge of cellular and molecular processes to understand infectious disease mechanisms

  synthesize knowledge of microbial pathogenesis and disease prevention methods and communicate this knowledge to the community

A scientific case study is a short summary of an event or personal experience that ends in a “mystery”—in this case, one that you will solve using your own research and the clues provided within the case study. For this project, you will evaluate a patient-centered case study that explores a mysterious bacterial or viral illness. The case study will include a set of questions to guide your analysis.

Your paper should include the following:

Case Study General Format:

Each of the 4 provided questions should be answered individually (200-300 words per question answer). You should incorporate your ideas into well-written paragraphs using complete sentences, a logical flow of information and in-text citations.

Reference citations should be provided at the end of the document formatted in the APA style.

Your Case study project should include the following:

1  Include your name, date and the case study title (“A”, “B”, “C”, etc…) at the top of your paper.

2  Number the question answers 1-4 in your document. DO NOT provide the original questions.

3  DO NOT copy the original case study into your response.

4  Answer each of the 4 question sections in 200-300 words.

5  Use in text citations for fact-based information

6  Provide APA formatted full reference citations at the end of the document.

7  Remember to use italics as needed for bacterial genus/species designations.

Once you have gathered all of your information, you will organize your case study analysis into an essay of 1,000 to 1,500 words (not including original case study OR references).


You must have a minimum of two outside sources to support your evaluation.

These can consist of any of the following: books, textbooks, scholarly journal articles, and websites run by reputable government organizations (such as the CDC or NIH).

You may have additional references as well. All of your references should be no more than six years old (published in 2005 or later).


You should include BOTH in-text citations and a final reference page formatted in APA style.
