Shiga toxin-producing E. coli (STEC) Infections Stx1, and Stx2 is an infection caused by certain Escherichia coli (E. coli) bacteria. These bacteria are germs that naturally live in the intestines and feces (poop) of many animals, especially farm animals (such as cows, goats, and sheep) and deer.
Not all types of E. coli bacteria make people sick, but a certain type of E. coli, called Shiga toxin-producing E. coli or “STEC” for short, makes a toxin (poison) that can make some people very sick (Diarrhea, cramping, Vomiting, Fever)
E. coli are a diverse group of bacteria that normally live in the intestines of humans and animals. Although some strains of these bacteria are harmless, some produce toxins that can make you sick and cause diarrhea (loose stool/poop) such as Shiga toxin-producing E. coli (STEC).
Who Gets Shiga-like toxin-producing Escherichia coli (STX1 and STX2) infections?
Shiga-like toxin-producing Escherichia coli (STX1 and STX2), often abbreviated SLT-producing E. coli or STEC, can infect anyone. However, certain groups are more susceptible and at higher risk of severe illness and complications:
Infants and young children, especially those under 5 years old, are particularly vulnerable to STEC infections. Their developing immune systems make it harder to fight off the bacteria, which can lead to more severe consequences such as hemolytic uremic syndrome (HUS), a serious condition affecting the kidneys.
Elderly individuals, especially those older than 65 years, are at increased risk because of potentially weaker immune systems and underlying health conditions that may complicate the course of the infection.
People who have weakened immune systems due to conditions like HIV/AIDS, cancer, or treatments such as chemotherapy and steroid medications are more susceptible to infections, including those caused by STEC.
People with diabetes, kidney disease, or any chronic illness that affects the immune response can also have a heightened risk of contracting and suffering severe outcomes from STEC infection.
Where Does STEC Come From? How Did I Get it?
How does Shiga-like toxin-producing Escherichia coli (STX1 and STX2) Spread? transmission of STEC infections can be sourced from several common vectors.
People become infected with STEC when they eat any product contaminated with the bacteria. The bacteria live in the intestines of healthy cattle, and contamination of their meat may occur during the slaughtering process.
Infection most typically occurs by eating contaminated food, particularly raw or undercooked meat,. Infection can also occur after eating any product contaminated with STEC, including lettuce, alfalfa sprouts, salami, and raw (unpasteurized) milk, juice, or cider.
Infected people can spread E. coli to other people if they do not wash their hands after using the toilet (day care centers, Senior Centers, Hospitals). Direct or indirect contact with animals, particularly in petting zoos, farms, or at fairs can result in transmission of STEC if proper hygiene practices are not followed.
High Levels of STX1 and STX2
What Does It Mean If My Levels of STX1 and STX2 are High? High levels of Shiga-like Toxin E. coli stx2 could indicate that you have been exposed to harmful E. coli bacteria, possibly through contaminated food or water. The presence of this toxin suggests that the bacteria are releasing Stx2, which can damage the cells lining your intestines and kidneys, making it more difficult for your body to fight off the infection. This could potentially lead to serious health issues such as severe stomach cramps, diarrhea, or even kidney damage.
It is important to be mindful of good hygiene and food safety practices to reduce the risk of exposure to these harmful bacteria.
The Shiga-like toxins disrupt protein synthesis in host cells by targeting ribosomes, leading to cell death. This can cause severe damage, particularly in the lining of the intestines, and can have systemic effects if the toxin enters the bloodstream.
Symptoms of High Levels of Shiga-Like Toxin E.Coli STX2
Symptoms of high levels of Shiga-like Toxin E. coli stx2 infections can vary, but most often include severe diarrhea (loose stool/poop), stomach cramps, and vomiting. Diarrhea is often bloody and usually little or no fever is present. Symptoms typically appear 3-4 days after eating (or having direct contact with) a contaminated product but can range from 1-10 days.
Toxins Production
STX1 (Shiga Toxin 1): This toxin is very similar to the toxin produced by Shigella dysenteriae.
STX2 (Shiga Toxin 2): This is a related but distinct toxin that can be even more potent than STX1 in causing severe disease.
Low Levels of Shiga-Like Toxin E.Coli STX2
What Does It Mean If My Levels of Shiga-Like Toxin E.Coli STX2 are Low
Low Levels of Shiga-like Toxin E. coli stx2 could indicate that your body has been exposed to a small amount of harmful E. coli bacteria, but not enough to cause severe health issues. This might be due to factors like a strong immune system, good hygiene practices, or even certain medications that help your body fight off infections. It’s still important to be cautious and maintain proper food safety measures to prevent further exposure to these bacteria, as they can cause more serious health problems if their levels increase.
Symptoms of Low Levels Shiga-Like Toxin E.Coli STX2
Complications Of STEC Infection
What Complications Can Result from Infection With STEC? In some people, particularly children under five years of age, infection can lead to the development of hemolytic uremic syndrome (HUS). HUS is a serious life-threatening disease that can cause kidney damage or failure and other serious problems. Hospitalization is often required because transfusions of blood, plasma exchange, or kidney dialysis may be necessary. Fortunately, most people with HUS recover completely within a few weeks, although for some it can be fatal.
How are Shiga toxin-producing E. coli infections diagnosed?
Shiga-like Toxin E. coli stx2 infections are most often diagnosed through laboratory testing of stool (poop) specimens. Detection of STEC is typically done by culturing a stool sample and confirming the presence of Shiga-like toxins or by specific molecular assays (PCR) that identify toxin genes.
What is the treatment for Shiga toxin-producing E. coli infections?
In tradtional medicine there is no specific medical treatment for Shiga-like Toxin E. coli stx2 infections. (*) Since diarrhea can cause dehydration (loss of water in the body causing weakness or dizziness), drinking plenty of fluids to stay hydrated is important.
Functional Medicine and Shiga toxin-producing E. coli infections
Functional medicine aims to address the underlying causes of disease, focusing on a holistic, patient-centered approach. When dealing with an infection caused by Shiga-like toxin-producing Escherichia coli (STEC), functional medicine doctors would incorporate a comprehensive strategy that includes at times both conventional and holistic therapies.
Use of natural supplements for symptom relief (e.g., electrolytes for rehydration, anti-inflammatory herbs) as well as things like high-quality probiotics to restore the gut microbiota balance and support the immune system are often recommended.
Other supplements might include Glutamine to support gut lining integrity, Slippery Elm and Marshmallow Root to help soothe the gastrointestinal tract. Activated Charcoal or some other binding agents to help bind and eliminate toxins from the gut. Emphasis on foods rich in fiber, antioxidants, and anti-inflammatory components to support gut and overall health and finally educating patients and caregivers about good hygiene practices to prevent the spread of infection.
Your specific treatment plan and recommendations will need to be tailored to your stool test (poop-test) results based on what your Fuctional Medicine doctor feels is most appropriate for you.
Antibiotics should not be used for the treatment of STEC infection since there is no evidence that antibiotics are helpful with these infections and may increase the risk of developing hemolytic uremic syndrome (HUS). (*)
What can be done to help prevent STEC infections?
- Always handle raw meat, especially ground beef, according to these recommendations: (*)
- Wrap fresh meats in plastic bags at the market to prevent blood and juices from dripping onto other foods. Refrigerate promptly; do not store at room temperature.
- Never place cooked food on an unwashed plate that previously held raw beef, poultry, pork, fish, or seafood.
- Cutting boards and counters used for beef, poultry, pork, fish, or seafood preparation should be washed immediately after use to prevent cross-contamination with other foods.
- Avoid eating raw or undercooked meats. While the juice color will usually change from red to gray when the meat is fully cooked, it is not a reliable test to ensure it is safe to eat.
- Always check the temperature of cooked foods with a meat thermometer. Foods that reach the temperatures listed below (or higher) are considered fully cooked.
| Food | Temperature |
| Chicken | 165° F |
| Hamburger | 160° F |
| Pork | 150° F |
| Hot dogs | 140° F |
| Leftovers | 165° F |
| Eggs | 145° F |
| Other foods | 140° F |
- Avoid drinking raw (unpasteurized) milk, juices, and ciders from animal contamination.(*)
- Wash fruits and vegetables thoroughly, especially those that will be eaten raw. (*)
- Wash hands with soap and water before and after food preparation, as well as, before eating. (*)
- Wash hands with soap and water after using the toilet, changing diapers, and after any animal contact (at home, farms, petting zoos, etc.) (*)
- Do not drink water from untreated sources (including roadside springs) and avoid swallowing water from recreational water sources (including lakes, streams, and swimming pools) when possible. (*)
