Case study II: Outbreak of Invasive Group A Streptococcus at a Child Care Center
Question A. What group of streptococci caused this outbreak? What species of streptococci in this group is most the most common to cause human diseases?
Question B. What characteristics of the bacterial pathogen in this outbreak enable it to cause invasive infections? Consider virulence factors (a pathogen-produced substance that promotes the establishment and maintenance of disease) of the bacteria.
Question C. How would you treat the following symptoms that can be caused by this group of streptococci:
a. Erysipelas (dermal layer infection, causes reddish skin patches with raised margins)

Question B. Why did each patient in the case study require mechanical ventilation? In your answer, include how the pathogen can lead to respiratory distress.
Question C. How is tetanus prevented?
Case study IV: Girl with rash

Question C. How is this condition treated?
Case study V: Meningitis outbreaks traced to raves and clubs
Question A. What are the key features of the disease in this case study that indicate it is meningitis and not simply a case of the "flu"?
