EPEC stands for enteropathogenic Escherichia coli. Escherichia coli is a group of bacteria that is divided into various subgroups, including the EPEC and EHEC (enterohaemorrhagic E. coli) groups.
EPEC is a special strain of the Escherichia Coli bacterium. Escherichia Coli bacteria can also be found in the intestines of healthy people. There they are part of the healthy intestinal flora and are not of any further concern. EPEC, on the other hand, are bacteria that are capable of causing diseases in humans.
EPEC bacteria cause infectious gastrointestinal infections, especially in infants and small children, less often in adults. EPEC infections nowadays occur mainly in developing countries with low hygiene standards, but have become rarer in Europe.

The human intestine contains numerous E. coli bacteria; they are part of the normal intestinal flora and do not cause disease. However, certain subtypes of E. coli, such as EPEC, can cause intestinal infections.
An infection with EPEC pathogens can take place in different ways. For example from person to person through faecal-oral transmission in the event of inadequate hygiene measures.

$config[ads_text2] not foundAn infection with EPEC bacteria is similar to a typical diarrheal illness. The incubation period is about a week. But symptoms are also possible after a few days.
Asymptomatic courses are also possible. In this case, no discomfort will be noticed. Nevertheless, pathogens may be excreted, so that asymptomatically infected people can continue to infect other people.

There are various ways of detecting an infection with EPEC pathogens. Either by detecting the pathogen or its components in a stool sample or by detecting specific antibodies against the EPEC pathogen in a blood test.

Escherichia Coli bacteria can be grown on special culture media and classified in this way. A laboratory can also accurately detect certain proteins that are only formed by EPEC. These proteins are also responsible for the pathogenic properties of the EPEC bacteria.
Diagnostics that are specifically aimed at the detection of EPEC pathogens are usually only carried out if there is justified suspicion of an infectious gastrointestinal disease, for example due to severe diarrhea lasting several days.
One of the most important therapeutic steps for diarrheal diseases is adequate fluid intake. A large amount of water is lost from the body due to the diarrhea. To compensate for this, care should be taken to drink enough. This is especially true for children.
$config[ads_text2] not foundThe intestinal absorption of water and electrolytes may no longer be sufficient to cover the losses. In this case, the fluid and salt balance can be balanced with infusions. Inpatient monitoring in a hospital may be necessary for this.
If the course is very severe, the kidneys can be impaired. In this case, dialysis can minimize damage.

The disease usually begins with watery diarrhea. The disease limits itself. This means that the pathogens are excreted with the stool via the intestine over a few days and are then mostly eliminated from the intestine after a certain period of time. Without complications, the diarrhea usually heals after a few days.
However, EPEC bacteria can also cause asymptomatic infections. In this case, the bacteria colonize the intestines without causing diarrhea or other symptoms.
EPEC bacteria can survive in the intestines of healthy people, especially with lower hygiene standards. Even if the affected persons show no symptoms themselves, they still excrete EPEC bacteria and can thus infect other people. Even after overcoming diarrhea, some of the EPEC bacteria can remain in the intestine.
The course of the disease with an EPEC infection is very variable. There is an incubation period before the first symptoms appear. This can last a few hours to days. The exact duration of the incubation period depends on a number of factors:
The disease can take a completely asymptomatic course - i.e. without the person concerned noticing it - but it can also lead to severe courses with massive dehydration (dehydration) and fatal course. This can also lead to bloody diarrhea.
In the industrialized nations, too, the infectious nature of the disease repeatedly leads to waves of disease in infant wards.However, the disease has become relatively rare in industrialized nations. In developing countries in particular, EPEC infections can contribute significantly to infant mortality.

EPEC bacteria are found in the intestines of infected people. But the bacteria can also multiply in different animals. This is why farms are an important reservoir for bacteria.
$config[ads_text1] not foundEPEC bacteria usually have to be ingested through the mouth for infection. This can happen through contaminated water or food.
Infected people can also spread the bacteria through direct contact. Hand washing or disinfection after using the toilet can limit the spread.
Yes. Evidence of EPEC pathogens in the laboratory (i.e. through examinations of stool samples sent in) must be reported.
The sick person must therefore be reported by name to the health department. Doctors are also required to report suspected infectious gastrointestinal disease (gastroenteritis), if the person concerned works in the food sector or if there are two or more cases of illness that are probably related.
Sick children are not allowed to go to daycare as long as they still have diarrhea symptoms. But even after the symptoms have subsided, meticulous hand hygiene is crucial.
Because the pathogens can still be excreted in the stool after the acute symptoms have subsided. The risk of a wave of illness is relatively high in facilities such as daycare centers.
In addition, the heads of community facilities are obliged to report to the health department by name if diarrheal diseases occur in their facility.
The most critical complication of EPEC enteritis is:
Infants and toddlers in particular have few resources to adequately counteract the heavy loss of fluids.
The loss of water and salt is particularly dangerous in diarrhea. The kidneys are central organs in the body's water balance.
In-patient admission with intravenous fluid therapy and, if necessary, antibiotic therapy may be necessary in order to compensate for the loss of fluid and thus prevent serious complications. In developing countries in particular, however, such therapeutic measures are often not possible, so that many children die as a result of dehydration.
