Case Study #6: A 20 year old male college student develops a fever after gall bladder surgery and has a pus exudate around the incision. You receive a cotton swab of the exudate which you streak on a blood agar plate. Bacterial colonies on the plate show B hemolysis, and microscopic examination reveals Gram + cocci occurring singly, in pairs, and in short chains. Further testing reveals that the isolate is catalase negative and phenol red fermentation broth with mannitol turns yellow. 1. What is the name of the most likely bacterium causing this infection? 2. What is the most likely place that this bacterium originated to cause this infection?

18 A 7-year-old boy presents to the emergency depart- ment with fever, abdominal pain, and tenderness in the right lower quadrant. A white blood cell count reveals leukocytosis.
