Case Study 3: A 3-year old girl presented at the emergency room with bloody diarrhea, fever and vomiting. The child’s mother reported that the day-care center called yesterday morning because she started having a watery diffuse diarrhea. That night she began to complain of severe cramps and her diarrhea became bloody and pus-filled. The family has no recent travel history and while they are vegetarians, they only consume pasteurized milk, cheese, and egg products. The gram stain showed many white blood cells and many gram-negative bacilli. The culture resulted in many translucent-clear colonies on the MacConkey’s agar that were oxidase negative and fermented glucose, but not lactose. She was admitted to the hospital to treat her dehydration and for observation. Case Study 3 Question 2: The symptoms of this infection were mediated by what virulence factor?
