Enteroaggregative E. coli - Information for Patients


What kind of infection is it?

E. coli is a bacteria that normally lives in the intestines of most people and most types are harmless. Enteroaggregative E. coli (or EAEC) is a special kind of E. coli that has several tools that make them able to cause diarrhea.

How do people get infected?

  1. EAEC infections are caused by exposure to food, ice, or water contaminated with human or animal waste.
  2. EAEC causes diarrhea in children in both poor and wealthy countries and in adults who travel to developing countries.

What are the usual symptoms?

  1. Illness usually starts 1-3 days after exposure.
  2. Watery diarrhea, stomach pain or cramps. Diarrhea may contain mucous. Fever is rare.

How long does it last?

  1. Typically 3-4 days but some people may be ill for 14 days or longer.

How is it treated?

  1. Prevent dehydration by drinking fluids. For young children, use a rehydration solution such as Pedialyte® or Rehydralyte®. Even a few sips or spoonfuls at a time can help. Warning signs of dehydration include dry mouth, decreased urination, or dizziness.
  2. Antibiotics may shorten the duration of diarrhea for people with EAEC infection but often are not necessary.

Are there possible complications?

  1. Dehydration from fluid loss is the major complication.

Comments:

  1. Until recently, most doctors were not able to diagnose EAEC because testing was only available in research labs. Now that testing is available, doctors are still learning about this infection.
  2. Wash hands carefully with soap and water after going to the bathroom or changing diapers, cleaning up vomit or stool.
  3. Clean contaminated surfaces and disinfect with bleach solution (5-25 tablespoons of household bleach per gallon of water).
  4. People with diarrhea should not prepare food.
