Alice spent the summer hiking in the jungles of Costa Rica. A few days before she returned home, she took a bad fall down the side of a ravine and received a deep cut to her femur. Her companions helped clean the wound and dress it and, returned to the hotel, where the hospital physician looked at it and complimented them on their thorough cleaning. On the plane two days later, Alice began running a temperature and felt generally ill. By the time she landed at LAX, she could barely walk. Her leg was swollen and emitted a peculiar sweet, grape-like odor.  What is your diagnosis?
