Escherichia coli O157 infection, often referred to as STEC (Shiga toxin-producing Escherichia coli), is a bacterial infection that can cause severe gastrointestinal and other health issues.
Understanding E. coli O157
Based on the provided reference, Escherichia coli O157 is a specific strain of the E. coli bacterium known for its potential to cause serious illness. Unlike many E. coli strains that live harmlessly in the gut, E. coli O157 produces powerful toxins, called Shiga toxins, which damage the lining of the intestine.
Symptoms of E. coli O157 Infection
Infection with E. coli O157 can lead to a range of symptoms. The reference highlights the severe manifestations:
- Severe stomach pain
- Bloody diarrhoea
- Kidney failure
While some people may have mild or no symptoms, others, particularly young children and the elderly, can develop a life-threatening complication called hemolytic uremic syndrome (HUS), which affects the kidneys.
Where is E. coli O157 Found?
According to the reference, E. coli O157 is commonly found in the gut and faeces of many animals. Cattle are specifically mentioned as common carriers. This means that environments or foods contaminated with animal faeces are potential sources of infection.
Common sources of exposure include:
- Eating undercooked ground beef
- Drinking unpasteurized milk or juice
- Drinking contaminated water
- Contact with farm animals (especially cattle) or their environment
- Person-to-person spread, particularly in settings like daycare centers
Key Takeaways
To summarize the essential points from the reference about Escherichia coli O157 infection:
- It is a bacterial infection.
- It is also known as STEC (Shiga toxin-producing Escherichia coli).
- It can cause severe symptoms like stomach pain, bloody diarrhoea, and kidney failure.
- The bacteria are found in the gut and faeces of many animals, especially cattle.
