Case Study #10: A 4-year old girl presents at the emergency room with bloody diarrhea, fever and vomiting. The child's mother reports that the child has had these symptoms for about 24 hours and she has not passed any urine for about 12 hours. The child is enrolled in a day care center and the group had recently made a field trip to a fast food place to learn about different jobs. The children had a lunch of ground beef, fries, and cola after meeting with different workers. This field trip was 4 days earlier on Friday. The child had a temperature of 39C and showed physical signs of dehydration. Blood samples drawn showed evidence of greatly reduced kidney function and lysed red biood cells. 1. What is your presumptive diagnosis for this patient? 2. What is the name of the most likely bacterium responsible? 3. What were the key critical features leading to your diagnosis? 4. Lab test(s) to confirm diagnosis? Expected results? 5. What virulence factor of this organism caused the severity of this problem?
