Microbial Pie, or What Did You Feed the Neighbors? 

The Emergency Room seems busier than usual, and the cases coming in are all too similar.  Everyone seems to be suffering from the same symptoms - abdominal pain, vomiting, and bloody diarrhea.  Once the hospital staff identify the bacteria causing the problems, the next step is tracking down the source.  This case uses a story of microbial contamination, combined with lab experiments, to teach skills in problem-solving, critical thinking, and experimental design and analysis.  It was developed for a general microbiology course primarily composed of health care students and biology majors planning to transfer to four-year schools. There are three labs associated with this case.
