A study is recently related An increase in cases of colon cancer for young people By Expression of toxins Made by bacteria They revealed the cold. In addition, it is associated with other different issues such as dangerous Hemolytic uremic syndrome Or Rare self-stylish syndrome.
In fact, the E. Cole It is the most common bacterium in our environment and even within our body. However, Most of the time it is harmlessAnd only in a few cases causes serious health problems. There are many types within the same species and this will have different effects on our body
Severe cases of severe and severe infections
As indicated World Health OrganizationLa bacteria They expressed the cold It is usually found in the intestines of humans and usually in hot blood animals, often there are harmless strains. However, there are some types of production A toxic called Shika or Calidoxin, It is dangerous and contaminated with contaminated food consumption usually causes severe diseases.
More specifically, the E. Cole Shika toxic producer (This is called to unity with toxins produced by another bacterial species, Shigella Tysontria) At a wide temperature (from 7 to 50 degrees Celsius, the option to about 37º). Many times, it is in acidic foods.
In most cases, this strain E. Cole Creates a disease characterized Stomach cramps and diarrheaIn some cases, bleeding is progressing in the colitis (diarrhea with blood) and even fever and vomiting. However, low percentage of people (especially children and older) can lead to a deadly film called uremic hemolytic syndrome, whose main features are severe renal failure, hemolytic anemia, and thrombocytopenia.
Is still rare Meningitis Source E. Cole, It always occurs in newborns and causes fever, neck erection, headache and neurological symptoms to the severity of the infection.
E. coli and colon cancer: different bacterium
Instead of, strain E. Cole Newly published inspection Nature Associated with an increase in recent decades Cancer cases in children under the age of 50 This is a different one, which creates a different toxicity called cholebuckin.
Unlike Callidoxin or Shika toxic, this compound is genotoxic: that is, Damages the DNA of cells. That is why it can produce mutations in intestinal cells, which can lead to cancer development for many years.
These are hereditary E. Cole They are associated with other chronic effects, such as intestinal inflammation (which can create conditions such as chron disease or ulcerative colitis) or dysposis (changes in intestinal plants) Breast Cancer Cases (According to a study published in 2023 Cells).
Prevention against E. Kolly
Today, the May Clinic (United States) We have no vaccines or drugs against us E. ColeSo it is our most effective tool for fighting it Barrier
The main precautions pass through, to avoid shrinking the harmful strain of this bacteria Cook the food correctly .
The absence of effective drug E. Cole It contains him Rest and transplant the liquidHospital in case of hemolytic uremic syndrome. The best way to overcome it is the risk of colon cancer, which is often undergoing colonoscopy for screenship tests (feces) when pointing.
