Protective Efficacy of a Single Daily Dose of Travelan Against Moderate-to-severe Diarrhea Following Challenge With Enterotoxigenic E. Coli (ETEC) Strain H10407.
Monitoring period - Days 1 to Day 5 post challenge

The number of subjects who encounter moderate to severe diarrhea (defined as ≥4 Grade 3-5 stools in any 24-hour period post-challenge or ≥401 grams of Grade 3-5 stools in the 5-day period post-challenge) will be recorded for the Travelan group and the placebo group. All stool samples will be collected, weighed and graded. Stool grading scale: Grade 1 = Fully formed (normal) Grade 2 = Soft (normal) Grade 3 = Thick liquid (diarrheal) Grade 4 = Opaque watery (diarrheal) Grade 5 = Rice-water (diarrheal). Diarrhea (Grade 3-5 stools) severity in a 24 hour period (1g = 1ml): 1-mild (2-3 loose/liquid stool totaling \<400 g), 2-moderate (4 to 5 loose/liquid stools or \>401 to 800 g), 3-severe (6 or more loose/liquid stools totaling \>800 g).
