Enterovirulent E. coli (EEC) Complications
All of the EEC groups may have complications associated with infection. However, some groups have far fewer and potentially less serious complications than other groups. All of the groups, however, have one potentially serious complication; dehydration. If left untreated, dehydration can lead to multiple organ damage and death. Severe dehydration happens infrequently in developed countries, but in third world countries. In general, in developed countries, ETEC, EAEC and EAggEC group infections have few complications develop.
A relatively frequent complication of EHEC, EPEC and EIEC is blood in the stool. Some individuals will have only a small amount of blood but others may have large amounts and may require a blood transfusion (severe hemorrhagic diarrhea).
However, about 10% of all persons infected with EHEC (usually E. coli 0157:H7) develop some complication. Occasionally, the complication(s) may lead to disability or death. EHEC strains (and sometimes, EIEC group organisms) may produce the serious problems listed below;
- Hemorrhagic (bloody) diarrhea: This complication can prolong the
disease by about a week, and cause severe abdominal pain. The individual may
also develop dehydration, anemia and may need a blood transfusion....
