• #1 Escherichia coli – Wikipedia

  https://en.wikipedia.org/wiki/Escherichia_coli

  Most E. coli strains do not cause disease, naturally living in the gut, but virulent strains can cause gastroenteritis, urinary tract infections, neonatal meningitis, hemorrhagic colitis, and Crohn’s disease. Common signs and symptoms include severe abdominal cramps, diarrhea, hemorrhagic colitis, vomiting, and sometimes fever. […] Some strains of E. coli, for example O157:H7, can produce Shiga toxin. The Shiga toxin causes inflammatory responses in target cells of the gut, leaving behind lesions which result in the bloody diarrhea that is a symptom of a Shiga toxin-producing E. coli (STEC) infection. This toxin further causes premature destruction of the red blood cells, which then clog the body’s filtering system, the kidneys, in some rare cases (usually in children and the elderly) causing hemolytic-uremic syndrome (HUS), which may lead to kidney failure and even death.

  Infection with E. coli O157:H7 can range in severity from causing no symptoms at all (asymptomatic infection), to a mild or modest watery diarrhea only, to severe bloody diarrhea, sometimes including severe complications and death. The classic picture of illness is severe, painful abdominal cramping (so severe that it sometimes gets mistaken for appendicitis) with watery diarrhea that turns bloody within 1 to 3 days. The bloody diarrhea can progress to the point that stools appears to be pure blood. Vomiting can occur as well. Importantly, fever is not a prominent part of illness due to E. coli O157:H7. Less than half of patients ever report a fever, and when they do, it is usually low grade (101.0oF). […] Overall, almost 40% of people with a laboratory-confirmed E. coli O157:H7 infection require hospitalization. Most people will recover within a week or so, but a subset of people become severely ill. Children and people 60 years in age are more likely to develop severe illness, including the life-threatening complication hemolytic uremic syndrome (HUS), which involves kidney failure. However, people of any age can be severely affected.

• #1 E. coli Infection: Symptoms and Prevention | familydoctor.org

  https://familydoctor.org/condition/e-coli-infection/

  E. coli is short for Escherichia coli—bacteria (germs) that are found on food and in the environment. E. coli cause severe cramps and diarrhea. These bacteria are a leading cause of bloody diarrhea. The symptoms are worse in children and older people, and especially in people who have another illness. E. coli infection is more common during the summer months and in northern states. […] Symptoms can start from 1 to 10 days after you’re exposed to the germ. The first symptoms are severe abdominal cramps that start suddenly. After a few hours, watery diarrhea starts. The diarrhea causes your body to lose fluids and electrolytes (dehydration). This makes you feel sick and tired. The watery diarrhea lasts for about a day and then may change to bright red bloody stools. The infection makes sores in your intestines, so the stools become bloody. The bloody diarrhea may last for 2 to 5 days. You might have 10 or more bowel movements a day. Some people say their stools are “all blood and no stool.” You may have a mild fever or no fever. You may also have nausea or vomiting. If you have any of these symptoms—watery, bloody diarrhea, cramps, fever, nausea, or vomiting—try to get to your doctor right away.

• #2 E. coli Infection: Symptoms and Prevention | familydoctor.org

  https://familydoctor.org/condition/e-coli-infection/

  E. coli is short for Escherichia coli—bacteria (germs) that are found on food and in the environment. E. coli cause severe cramps and diarrhea. These bacteria are a leading cause of bloody diarrhea. The symptoms are worse in children and older people, and especially in people who have another illness. E. coli infection is more common during the summer months and in northern states. […] Symptoms can start from 1 to 10 days after you’re exposed to the germ. The first symptoms are severe abdominal cramps that start suddenly. After a few hours, watery diarrhea starts. The diarrhea causes your body to lose fluids and electrolytes (dehydration). This makes you feel sick and tired. The watery diarrhea lasts for about a day and then may change to bright red bloody stools. The infection makes sores in your intestines, so the stools become bloody. The bloody diarrhea may last for 2 to 5 days. You might have 10 or more bowel movements a day. Some people say their stools are “all blood and no stool.” You may have a mild fever or no fever. You may also have nausea or vomiting. If you have any of these symptoms—watery, bloody diarrhea, cramps, fever, nausea, or vomiting—try to get to your doctor right away.

  E. coli is a well-known risk factor in food preparation and hygiene, but how does it cause damage in the body and how does an outbreak have the power to send hundreds to hospital, potentially with kidney damage? […] Severe illness linked to E. coli is all about the strain involved. Some strains of E. coli are relatively harmless, while others cause serious illness ranging from diarrhea, to bloodstream infections, to organ damage. The strains associated with outbreaks tend to have a very low infectious dose (the minimum number of bacteria you need to ingest in order to become infected) and so even a small number of bacteria can spread to many people relatively easily. […] Infections caused by Shiga toxin-producing E. coli can have quite serious short and longer-term effects. In the short term, about 10 per cent of people infected will develop kidney damage associated with the bacterias toxin. This condition is called hemolytic uremic syndrome (HUS) and requires dialysis to help the body remove toxins while the kidneys try to recover. In extremely serious cases, the kidneys may sustain permanent damage that limits their function. These infections have also been associated with increased risk of chronic gut disorders, like irritable bowel syndrome, and disease, like inflammatory bowel disease (ulcerative colitis and Crohns disease). This increased risk for IBS and IBD can last for years after the infection first took place.

  Haemolytic uraemic syndrome (HUS): A triad of acute kidney injury (oliguria and oedema), haemolytic anaemia and thrombocytopenia. It mainly occurs in young children and is the major cause of acute kidney injury in children in Britain. HUS, if it occurs, is usually diagnosed 5-13 days after the onset of diarrhoea, and thrombocytopenia is usually the first feature. HUS develops in up to 15% of patients infected with E. coli O157. […] Thrombotic thrombocytopenic purpura (TTP): Some patients, usually adults, develop TTP. This is similar to HUS, but with less renal involvement and more prominent neurological features. […] Most patients recover spontaneously by 1-2 weeks after symptoms start. Infants, children and the elderly are at greatest risk of complications. […] For children aged 10 years, the risk of developing HUS is about 15%. Overall, approximately 5% of infected patients develop HUS. The case fatality rate of HUS is about 10%. […] The fatality rate of E. coli O157 infections is very variable and depends on the ages of the groups affected. Fatality rates ranging from 1-5% have been reported, but may be much higher in some institutional outbreaks.

[…] Symptoms of infection with E. coli 0157 typically appear 3 to 4 days after being exposed to the bacteria. However, symptoms may appear as early as 24 hours or as late as 1 week later. […] These can include: abdominal pain or severe abdominal cramping, often starting suddenly; watery diarrhea, beginning a few hours after the pain begins; bright red bloody stools around a day later, resulting from the toxins damage to the intestines; nausea and, in some cases, vomiting; in some cases, fever, usually below 101 degrees Fahrenheit; fatigue, resulting from dehydration and the loss of fluids and electrolytes.
