E.coli and other Enterobacteriaceae infections: Causes
(Handbook of Diseases)

Although some strains of E. coli exist as part of the normal GI flora, infection usually results from certain nonindigenous strains. For example:

❑ Noninvasive diarrhea results from two toxins produced by strains called enterotoxic or enteropathogenic E. coli. These toxins interact with intestinal juices and promote excessive loss of chloride and water.

❑ In the invasive form, E. coli directly invades the intestinal mucosa without producing enterotoxins, thereby causing local irritation, inflammation, and diarrhea. Normal strains can cause infection in immunocompromised patients.

Transmission can occur directly from an infected person or indirectly by ingestion of contaminated food or water or contact with contaminated utensils. Incubation takes 12 to 72 hours.

Incidence

The incidence of E. coli infection is highest among travelers returning from other countries, particularly Mexico and those in Southeast Asia and South America. E. coli infection also induces other diseases, especially in people whose resistance is low. Another strain, E. coli 0157:H7, has been reported. It’s associated with undercooked hamburger and produces hemorrhagic colitis and hemolytic uremic syndrome in children, a principal cause of acute kidney failure in children.
