e. coli its normal flora.
Normal flora is present throughout the body and on all areas of the skin. Every body orifice (opening) contains normal flora: the mouth, ears, vagina, and rectum. E-Coli exists in the intestines. The skin contains a variety of flora that can turn into pathogens under the right conditions.
E. coli is part of the normal flora in the intestines and is secreted with faeces. It may enter water by faecal contamination of the water supply.
Yes, usual flora, normal flora, and typical flora are all normal results.
Gram-negative rods, mostly E. coli, are the most prevalent bacteria in our guts. Most E. coli are normal flora, only a few strains are pathogenic. Lactobacilli, which are gram-positive rods, are also in our guts.
Several species of bacteria are abundant in the human colon for aid in digestion. One of the common species is E. coli.
Another term for normal flora is indigenous microbiota or resident flora.
Normal flora exists on and in the body. But certain normal flora lives only in certain body areas. For example, we have E-Coli microorganisms in the large intestines, rectum, and on the skin around the anus. If that flora is "moved" to a different body area, say in the mouth (from not washing hands after wiping away a bowel movement) or in the vagina (from wiping back to front), then infection can occur. Some diseases make normal flora multiply. For example, yeast is found on the skin, mouth, and in the vagina. People with diabetes can have frequent yeast infections in the mouth, vagina, and in skin folds.
You said that in your answer too. As the flora is normal, there is no harm
E. coli are part of the normal flora of the gut. Meaning that they have a home there. They make vitamin K. They also prevent pathogenic bacteria from establishing themselves in the gut. They make it hard for them to get started.
Normal flora cannot cause a "disease". But if normal flora is disrupted it can become a pathogen and then cause infection. Some diseases, like diabetes, can disrupt normal flora and cause infection, especially yeast infections on the skin or in the vagina of women.
E. coli is the abbreviated name of the bacterium in the Family Enterobacteriaceae named Escherichia (Genus) coli (Species). Dave Graham in the Department of Microbiology, University of Illinois at Urbana/Champaign, recently pointed me to information gleaned from G.W. Tannock's book, Normal Microflora,1995, Chapman & Hall, which reveals that approximately 0.1% of the total bacteria within an adult's intestines (on a Western diet) is represented by E. coli. Although, in a newborn infant's intestines E. coli, along with lactobacilli and enterococci represent the most abundant bacterial flora.In fact, it is for this reason that the organisms which happily inhabit the intestinal tract as normal flora are named enteric bacteria. The Family to which E. coli belongs (Enterobacteriaceae, is named what it is - because of the Greek word enterikos - which pertains to the intestine. The name Escherichia comes from the name of the person Escherich, who in 1885 first isolated and characterized this bacterium.
