Case Study for TWiP 197

Gentleman in late 20s, has for weeks had watery diarrhea that is not getting better. Recently took trip to Oaxaca, Mexico. Stayed at nice hotel, all fruits, vegetables, salads well cleaned. Always ate at hotel. Developed diarrhea there. Went with three others, stayed at same place. No prior surgeries, no family history, no medications, no toxic habits. Daniel recommends one test and that gives diagnosis and therapy and he resolves.
