Toxin produced by E. coli bacteria also has nondiarrheal effects on the digestive tract

For people in wealthy countries, diarrhea is usually nothing more than an uncomfortable inconvenience for a few days. But for a poor child in a developing country, repeated bouts of diarrhea can lead to serious health consequences such as malnutrition, stunted growth and cognitive deficits.
