Case Study Lab Report for Lab 14: Streptococcus and Enterococcus
The concept behind the case studies presented in Lab 14 used to illustrate the genus Streptococcus and the genus Enterococcus is for you and your lab partners as a group to:
1. Determine whether or not the patient in case study #1 has streptococcal pharyngitis.
2. Come up with a valid diagnosis of the infectious disease in case study #2 and identify the bacterium causing that infection.
3. Support your group’s diagnose based on:
a. Any relevant facts in the patient’s history.(A reliable on-line source will be used to support this.)
b. The patient’s signs and symptoms. (A reliable on-line source will be used to support this.)
c. Each of the individual lab tests given in your case study.
d. All microbiological lab tests you performed as part of the project.
The due date for this report can be found on the class calendar. Your grade for this lab is based on the completeness of your report and written evidence of the critical thinking process that went into making and supporting your diagnosis. Remember, you are trying to convince your instructor that you understand how the diagnosis was made by supporting that diagnosis with data.
Grading:
The lab 14 Lab Report is worth 21 points each.
These case studies are based in part on your in-class participation as part of your group. Therefore:
a. If you were not in lab when the inoculations with your unknown were performed, 3 points will be deducted from your Lab Report score for labs 12, 14, and 15; 6 points from your Lab Report score for the Final Project.
b. If you were not in lab when the results of your lab tests were observed, 3 points will be deducted from your Lab Report score for labs 12, 14, and 15; 6 points from your Lab Report score for the Final Project..
c. For each day your Lab Report is late, 2 points will be deducted from your Lab Report score for labs 12, 14, and 15; 4 points from your Lab Report score for the Final Project.
Be sure to handle all the bacterial cultures you are using in lab today as if they are pathogens! Be sure to wash and sanitize your hands well at the completion of today’s lab.
Also, make sure you observe the results of of someone in your lab who had an unknown different from yours in case study #1. The Performance Objectives for Lab 14 tell you what you are expected to be able to do on the practical.
Each member of the group must:
1. Print a copy of each of the two rubrics from the links above.
2. Print and fill out a copy of the Team Member Evaluation Form from the link above.
3. Staple them together and hand them in to me the day your Lab 14 Case Study Lab Report is due.

A. Case Study #1 from Lab 14: Unknown #1
A 21-year old male complains of a sore throat and painful swallowing. A physical exam of the throat shows tonsillopharyngeal edema and erythema, a patchy exudate, petechiae on the soft palate, and a red, swollen uvula. He has a temperature of 101.6 °F. He doesn't have a cough or a noticeably runny nose.
1. Patient’s signs and symptoms
Read the case study. Explain how the patient’s signs and symptoms contributed to your diagnosis of the type of infectious disease seen here. Signs refer to anything being measured by a medical professional during a physical exam such as blood pressure, respiration rate, heart rate, oxygen saturation, and temperature. Symptoms refer to symptoms being reported by the patient. You are urged to use the computers in lab to search reliable medically oriented Internet sources to support this. Reliable sources you might consider are Medscape (http://emedicine.medscape.com/infectious_diseases) and The Centers for Disease Control and Prevention (CDC) at http://www.cdc.gov/. Cite any sources you use at the end of this Patient's Symptoms section in APA style (https://www.scribbr.com/apa-examples/website/). Also see appendix F (SIRS and Sepsis) in your lab manual for an indication of whether or not the patient has SIRS.
The patient's signs and symptoms should suggest a general type of infectious disease that is present, such as a urinary tract infection, a wound infection, gastroenteritis, pharyngitis, pneumonia, septicemia, etc. You need to determine the general type of infection in order to determine what microbiological tests to perform to identify the bacterium causing the infection. Search at least one medically oriented reference article from a reliable site such as Medscape and use this article to support your diagnosis of the type of infectious disease seen here. Don't forget to cite any sources you used in APA style directly under this Patient's Signs and Symptoms sections of this Lab Report.
2. Vocabulary list for medical terms used in the case study under signs and symptoms
List and define any medical terms used in your case study that describe the patients’s signs and symptoms that the average person not in the medical profession might not know.
3. Microbiological lab tests you performed in Lab 14
a. Blood agar with Taxo A® (bacitracin) disk: Unknown #1
Give the results of the Blood agar with Taxo A® (bacitracin) disk you performed on the unknown you were given, and how you reached this conclusion. State how this contributed to your final diagnosis as to whether or not the person has streptococcal pharyngitis. The possible results for blood agar and Taxo A® disk were discussed in the beginning pages of this lab.
4. If he has streptococcal pharyngitis, state the genus and species of this bacterium.
