Escherichia coli O104:H21
Serotype of bacterium
From Wikipedia, the free encyclopedia
Escherichia coli O104:H21 is a rare serotype of Escherichia coli, a species of bacteria that lives in the lower intestines of mammals.[1] Some serotypes of E. coli have been recognized as pathogenic to humans, e.g. E. coli O157:H7, E. coli O121 and E. coli O104:H21.

History
Escherichia coli O104:H21 was discovered in 1982, when it caused an outbreak of severe bloody diarrhea. It had infected hamburgers, and those affected had eaten these hamburgers not fully cooked.[2]
An outbreak of E. coli responsible for at least 22 deaths in Northern Europe in May 2011 was reported to be caused by another O104 strain, Escherichia coli O104:H4.[citation needed]
Effects
Escherichia coli O104:H21 can cause outbreak of infection similar to that caused by E. coli O157:H7, the most common shiga-like toxin-producing E. coli (SLTEC). SLTECs are the most well-known causes of gastrointestinal illness and diarrhea.[3]
Treatment
The body usually rids itself of harmful E. coli O104:H21 on its own within 5 to 10 days. Antibiotics should not be used, and neither should antidiarrheal agents such as loperamide.[2]
