Part 1-Trouble in the Nursery What are some possible causes of skin infections? List at least 5 DIFFERENT organisms (include genus and species, if applicable). Briefly describe the problem each can cause.

Part 2-Plan of Attack You are the microbiologist in charge of reading the Gram stain for this case. You observe Gram positive cocci, epithelial cells, and neutrophils. List at least two genera of clinically significant bacteria that are consistent with your observation.

Part 3-Tracking the Culprit What is the purpose of the four types of media listed (5% sheep blood agar, MacConkey agar, CNA and PEA agar)? Be specific. Which aerobic Gram positive cocci are normal flora on the skin (at least 2)?

Part 4-Eureka! Identify the organism. Include both genus and species. Identify the disease. Explain the rash. Here I am looking for a specific virulence factor that is responsible for the rash. How should it be treated? Many people, especially healthcare workers, carry Staphylococcus aureus in the anterior nares. How, then, are infections passed from these caregivers to their patients? How can transmission be prevented?

Part 5-From Nightmare to Naptime Write 100 words on the Significance of the case study to you and how it relates to problems we face today.
