All are TRUE about Enteroheomarrhagic E Coli(EHEC), EXCEPT:
**Core Concept**
Enteroheomarrhagic E. coli (EHEC) is a type of Shiga toxin-producing E. coli (STEC) that causes severe foodborne illness, characterized by hemorrhagic colitis and potential development of hemolytic-uremic syndrome (HUS).
**Why the Correct Answer is Right**
The key features of EHEC include the production of Shiga toxin, which is encoded by the Shiga toxin genes (stx1 and stx2), and adherence to the intestinal epithelium through specific adhesins like intimin. This adherence enables the bacteria to form attaching and effacing lesions, leading to the characteristic bloody diarrhea and potential complications like HUS. The Shiga toxin produced by EHEC is responsible for the damage to the intestinal lining and the subsequent development of HUS.

**Option D:** Not provided. If an option were given, I'd be happy to explain why it's incorrect.
**Clinical Pearl / High-Yield Fact**
In the context of EHEC infection, early recognition and management are crucial to prevent the development of HUS. This includes prompt initiation of supportive care, fluid resuscitation, and monitoring for signs of HUS, such as thrombocytopenia, microangiopathic hemolytic anemia, and acute kidney injury.
**Correct Answer:** D
