E. coli or Escherichia coli is a type of bacteria that occurs naturally in the intestine. The bacterial strain was named after its discoverer, the German pediatrician Theodor Escherich. As a natural bacterium in the intestinal tract of humans, other mammals and birds most E. coli bacteria are harmless<\/strong>.However, there are also strains of bacteria that are pathogenic, i.e. disease-causing, and can lead to bacterial infections. If there are apathogenic (non-pathogenic) E. coli bacteria in the intestine, this is not of further concern. Pathogenic species, on the other hand, are dangerous to health: if they reach other parts of the body outside the intestine, the risk of infection or disease is increased.<\/p>\n\n\n\n Many people are afraid of catching a gastro-intestinal infection in hospitals, public toilets or on the train, for example. E. coli bacteria are often the cause of such infections. It is not without reason that bacterial strains of the genus Escherichia are often referred to as faecal bacteria. This name is not wrong. Nevertheless, it does not do justice to this intestinal bacterium<\/strong>. After all, there is a large number of E. coli bacteria in the human intestine which are harmless and do not cause diseases.<\/p>\n\n\n\n E. coli even proves its usefulness in the intestinal flora as a vitamin producer<\/strong>. Thus E. coli bacteria make a valuable contribution to the formation of various B vitamins and vitamin K. In addition, some strains support the breakdown of nutrients such as proteins and carbohydrates. Nevertheless, E. coli is rather underrepresented in the intestine compared to other intestinal bacteria<\/a>. Only about one percent of your gut flora microbiota consists of coli bacteria.<\/p>\n\n\n\n Intestinal bacteria such as the Bacteroidetes<\/a> and Firmicutes are significantly more common. In general: If the bacterial balance in your intestinal flora is in equilibrium, most E. coli bacteria cannot harm you.<\/p>\n\n\n\n However, despite all the positive effects that E. coli has on your intestines, a general awareness of the bacterium is not wrong. Pathogenic E. coli bacteria can be the cause of many diseases, some of them serious, and have already caused some serious epidemics in the past.<\/p>\n\n\n\n E. coli bacteria are one of the most common causes of disease and they are widespread: On the one hand, E. coli bacteria often occur in places with lack of hygiene<\/strong> \u2013 especially toilets \u2013 and are spread from there. On the other hand, the germ also hides in foods such as raw meat, dairy products and fruit and vegetables.<\/p>\n\n\n\n In areas of the world where hygiene standards are low, E. coli bacteria can even be found in drinking water. In this country, the limit value for E. coli in drinking water is zero bacteria per 100 millilitres of water. This value must be strictly observed. In bathing water, however, the EU Bathing Water Regulation allows up to 500 bacteria in 100 millilitres ( water with excellent quality) or 1,000 bacteria per 100 millilitres of water (water with good quality).<\/p>\n\n\n\n Most of the E. coli bacteria found in the intestine do not cause disease. However, if you are infected by a smear infection<\/strong> or if bacteria reach other organs, the risk of disease is high. Pathogenic strains penetrate the intestinal wall, produce toxic substances there and can lead to more or less severe intestinal diseases<\/a>. A total of five groups of pathogenic strains can be distinguished.<\/p>\n\n\nAre E. coli bacteria in the gut dangerous?<\/h2>\n\n\n\n
