Escherichia är ett släkte av gramnegativa, icke sporbildande, fakultativt anaeroba och stavformiga bakterier i familjen Enterobacteriaceae. [1]De flesta av släktets bakterier är ofarliga, men Escherichia coli, som är en vanlig bakterie orsakar många vanliga infektioner som till exempel urinvägsinfektion.

One strain, E. coli O157:H7, produces a powerful toxin (poison), and can cause severe illness, kidney failure and even death. The symptoms of E. coli O157:H7 are diarrhea or bloody diarrhea, abdominal cramps, nausea, and malaise. Symptoms can begin 2 to 5 days after food is eaten, lasting about 8 days.

Escherichia coli is a common member of the normal flora of the large intestine. As long as these bacteria do not acquire genetic elements encoding for virulence factors, they remain benign commensals. E. coli are Gram-negative bacteria, thus red or pink colored. The red color is due to a counterstain, called safranin. Escherichia coli is frequently in the news (Fig. 1).

The bacteria in the community are often collectively known as gut bacteria. The intestinal flora mainly consists of the bacteria, yeasts, and protozoa that live in our large intestine. Escherichia coli (/ ˌ ɛ ʃ ə ˈ r ɪ k i ə ˈ k oʊ l aɪ /), also known as E. coli (/ ˌ iː ˈ k oʊ l aɪ /), is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms (endotherms). Escherichia coli (E. coli) bacteria normally live in the intestines of healthy people and animals.

Antalet E. coli -bakterier i en människas avföring varierar mellan 100 miljarder och 10 biljoner per gram avföring. 2021-04-12 · Escherichia coli (or simply E. coli) is one of the many groups of bacteria that live in the intestines of healthy humans and most warm-blooded animals. E. coli bacteria help maintain the balance of normal intestinal flora (bacteria) against harmful bacteria and synthesize or produce some vitamins.

E. coli in water is a strong indicator of sewage or animal waste contamination. Sewage and animal waste can contain many types of disease causing organisms. Escherichia coli (E. coli) is a Gram-negative, rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms (endotherms). Most E. coli strains are harmless, but some serotypes are pathogenic and can cause serious food poisoning in humans and other species.

However, there are certain types of E. coli strains that are a risk to human health including those that are capable of producing toxins. Escherichia coli (E. coli) bacteria normally live in the intestines of people and animals. Most E. coli are harmless and actually are an important part of a healthy human intestinal tract. However, some E. coli are pathogenic, meaning they can cause illness, either diarrhea or illness outside of the intestinal tract.
