Gut flora, gut microbiota or gastrointestinal microbiota is the complex community of microorganisms that live in the digestive tracts of humans and other animals, including insects. The gut metagenome is the aggregate of all the genomes of gut microbiota. The gut is one niche that human microbiota inhabit. In humans, the gut microbiota has the largest numbers of bacteria and the greatest number of species compared to other areas of the body. Chicken Invaders 5 Full Version. In humans the gut flora is established at one to two years after birth, and by that time the intestinal epithelium and the intestinal mucosal barrier that it secretes have co developed in a way that is tolerant to, and even supportive of, the gut flora and that also provides a barrier to pathogenic organisms. The relationship between some gut flora and humans is not merely commensal a non harmful coexistence, but rather a mutualistic relationship. Some human gut microorganisms benefit the host by fermentingdietary fiber into short chain fatty acids SCFAs, such as acetic acid and butyric acid, which are then absorbed by the host. Intestinal bacteria also play a role in synthesizing vitamin B and vitamin K as well as metabolizing bile acids, sterols, and xenobiotics. The systemic importance of the SCFAs and other compounds they produce are like hormones and the gut flora itself appears to function like an endocrine organ,6 and dysregulation of the gut flora has been correlated with a host of inflammatory and autoimmune conditions. The composition of human gut microbiota changes over time, when the diet changes, and as overall health changes. A systematic review from 2. ClassificationseditThe microbial composition of the gut microbiota varies across the digestive tract. In the stomach and small intestine, relatively few species of bacteria are generally present. The colon, in contrast, contains a densely populated microbial ecosystem with up to 1. These bacteria represent between 3. However, 9. 9 of the bacteria come from about 3. As a consequence of their abundance in the intestine, bacteria also make up to 6. Fungi, archaea, and viruses are also present in the gut flora, but less is known about their activities.

The Deir Yassin massacre took place on April 9, 1948, when around 120 fighters from the Zionist paramilitary groups Irgun and Lehi attacked Deir Yassin, a Palestinian. The National Wildlife Federations family of magazines include National Wildlife, Ranger Rick, Ranger Rick Jr., and Ranger Rick Cub. Over 9. 9 of the bacteria in the gut are anaerobes, but in the cecum, aerobic bacteria reach high densities. It is estimated that these gut flora have around a hundred times as many genes in total as there are in the human genome. Virtual Chemistry Lab 2.0 here. Many species in the gut have not been studied outside of their hosts because most cannot be cultured. While there are a small number of core species of microbes shared by most individuals, populations of microbes can vary widely among different individuals. Within an individual, microbe populations stay fairly constant over time, even though some alterations may occur with changes in lifestyle, diet and age. The Human Microbiome Project has set out to better describe the microflora of the human gut and other body locations. The four dominant bacterial phyla in the human gut are Firmicutes, Bacteroidetes, Actinobacteria, and Proteobacteria. Most bacteria belong to the genera Bacteroides, Clostridium, Faecalibacterium,91. Eubacterium, Ruminococcus, Peptococcus, Peptostreptococcus, and Bifidobacterium. Other genera, such as Escherichia and Lactobacillus, are present to a lesser extent. Species from the genus Bacteroides alone constitute about 3. Fungal genera that have been detected in the gut include Candida, Saccharomyces, Aspergillus, Penicillium, Rhodotorula, Trametes, Pleospora, Sclerotinia, Bullera, and Galactomyces, among others. Rhodotorula is most frequently found in individuals with inflammatory bowel disease while Candida is most frequently found in individuals with hepatitis B cirrhosis and chronic hepatitis B. Archaea constitute another large class of gut flora which are important in the metabolism of the bacterial products of fermentation. EnterotypeeditAn enterotype is a classification of living organisms based on its bacteriological ecosystem in the human gut microbiome not dictated by age, gender, body weight, or national divisions. There are indications that long term diet influences enterotype. Three human enterotypes have been proposed,2. Flora compositioneditAnatomyeditStomach floraeditDue to the high acidity of the stomach, most microorganisms cannot survive there. The main bacterial inhabitants of the stomach include Streptococcus, Staphylococcus, Lactobacillus, Peptostreptococcus, and types of yeast. Helicobacter pylori is a Gram negative spiral organism that establishes on gastric mucosa causing chronic gastritis and peptic ulcer disease and is a carcinogen for gastric cancer. Intestinal floraeditThe small intestine contains a trace amount of microorganisms due to the proximity and influence of the stomach. Gram positive cocci and rod shaped bacteria are the predominant microorganisms found in the small intestine. However, in the distal portion of the small intestine alkaline conditions support gram negative bacteria of the Enterobacteriaceae. The bacterial flora of the small intestine aid in a wide range of intestinal functions. The bacterial flora provide regulatory signals that enable the development and utility of the gut. Overgrowth of bacteria in the small intestine can lead to intestinal failure. In addition the large intestine contains the largest bacterial ecosystem in the human body. About 9. Bacteroides and Bifidobacterium. Factors that disrupt the microorganism population of the large intestine include antibiotics, stress, and parasites. Bacteria make up most of the flora in the colon2. This fact makes feces an ideal source to test for gut flora for any tests and experiments by extracting the nucleic acid from fecal specimens, and bacterial 1. S r. RNA gene sequences are generated with bacterial primers. This form of testing is also often preferable to more invasive techniques, such as biopsies. Somewhere between 3. However, it is probable that 9. Faecalibacterium prausnitzii being the most common species in healthy adults. Fungi and protozoa also make up a part of the gut flora, but little is known about their activities. The virome is mostly bacteriophages. Research suggests that the relationship between gut flora and humans is not merely commensal a non harmful coexistence, but rather is a mutualistic, symbiotic relationship. Though people can survive with no gut flora,2. K, and producing hormones to direct the host to store fats. Extensive modification and imbalances of the gut microbiota and its microbiome or gene collection are associated with obesity. However, in certain conditions, some species are thought to be capable of causing disease by causing infection or increasing cancer risk for the host. It has been demonstrated that there are common patterns of microbiome composition evolution during life. In general, the diversity of microbiota composition of fecal samples is significantly higher in adults than in children, although interpersonal differences are higher in children than in adults. Much of the maturation of microbiota into an adult like configuration happens during the three first years of life. As the microbiome composition changes, so does the composition of bacterial proteins produced in the gut.
