Question

Enterohaemorrhagic E coli (EHEC) sometimes is also known as:

• A. Enteropathogenic E coli (EPEC)
• B. Verotoxin producing E coli (VTEC)
• C. Entero invasive E coli (EIEC)
• D. Entero toxigenic E coli (ETEC)

Hint:

Enterohaemorrhagic E coli (EHEC) is known for producing verotoxin, which leads to severe gastrointestinal issues. It's important to recognize this strain due to its potential to cause hemolytic uremic syndrome.

Answer 1

The Correct Option is B

Enterohaemorrhagic E. coli (EHEC) is a type of Escherichia coli that produces a toxin called verotoxin. This toxin is responsible for causing severe gastrointestinal illnesses, including hemorrhagic colitis and hemolytic uremic syndrome. EHEC is commonly referred to as Verotoxin-producing E. coli (VTEC).
- Enteropathogenic E coli (EPEC): This is another strain of E. coli that causes diarrheal disease but is not related to the verotoxin produced by EHEC.
- Verotoxin producing E coli (VTEC): Correct! This is another name for Enterohaemorrhagic E. coli (EHEC), as it is defined by the production of verotoxins.
- Entero invasive E coli (EIEC): EIEC is another pathogenic strain of E. coli that invades the intestinal lining but does not produce the same toxins as EHEC.
- Entero toxigenic E coli (ETEC): This strain of E. coli produces enterotoxins and is associated with traveler's diarrhea, but it is not involved in the hemorrhagic conditions caused by EHEC.
Thus, the correct answer is (2) Verotoxin producing E coli (VTEC).
