†World Health Organization Collaborating Centre for Research on Enterotoxigenic Escherichia coli strain collection number.
‡Classification of diarrheal disease severity in travelers was based on the study case definition of travelers’ diarrhea with an associated gastrointestinal symptom rated as mild, moderate, or severe (5). Moderate symptoms interfered with daily activity, and severe symptoms prevented normal daily activity. Disease classification in children was based on the number of diarrheal stools in a 24-hour period (3/24 h, mild; 4–5/24 h, moderate; >6/24 h, severe). Diarrhea accompanied by vomiting was classified as severe; diarrhea lasting >14 days was classified as persistent.
§Not travelers’ diarrhea.
¶Strains E844 and E850 were isolated from the same person participating in the antimicrobial drug treatment study. Strain E850 was isolated after completion of a course of antimicrobial drugs.
