Ruminococcus Flavefaciens
''Ruminococcus'' is a genus of bacteria in the class Clostridia. They are anaerobic, Gram-positive gut microbes. One or more species in this genus are found in significant numbers in the human gut microbiota. The type species is ''R. flavefaciens''. As usual, bacteria taxonomy is in flux, with Clostridia being paraphyletic, and some erroneous members of ''Ruminococcus'' being reassigned to a new genus ''Blautia'' on the basis of 16S rRNA gene sequences. One of the most highly cited papers involving the genus ''Ruminococcus'' is a paper describing interspecies hydrogen transfer between ''Ruminococcus albus'' and ''Wolinella succinogenes''. In 1972, ''Ruminococcus bromii'' was reportedly found in the human gut, which was the first of several species discovered. They may play a role in plant cell wall breakdown in the colon. One study found that ''R. albus'', ''R. callidus'', and ''R. bromii'' are less abundant in people with inflammatory bowel disease. ''Ruminococcus'' are also ...

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflammatory Bowel Disease
Inflammatory bowel disease (IBD) is a group of inflammation, inflammatory conditions of the colon (anatomy), colon and small intestine, Crohn's disease and ulcerative colitis being the principal types. Crohn's disease affects the small intestine and large intestine, as well as the mouth, esophagus, stomach and the anus, whereas ulcerative colitis primarily affects the colon and the rectum. IBD also occurs in dogs and is thought to arise from a combination of host genetics, intestinal microenvironment, environmental components and the immune system. There is an ongoing discussion, however, that the term "chronic enteropathy" might be better to use than "inflammatory bowel disease" in dogs because it differs from IBD in humans in how the dogs respond to treatment. For example, many dogs respond to only dietary changes compared to humans with IBD, who often need Immunosuppression, immunosuppressive treatment. Some dogs may also need immunosuppressant or antibiotic treatment when dieta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruminococcus Obeum
''Blautia obeum'' is a species of anaerobic, gram-positive bacteria found in the gut. It has been shown that ''B. obeum'' along with other relevant taxa play an important role both in the recovery process from ''Vibrio cholerae'' infection and microbiota maturation in children. Moreover, experiments in model mice show that ''B. obeum'' strain AI-2 reduces the pathogenicity of ''V. cholerae''. The data show that the expression of quorum sensing autoinducers by ''B. obeum'' is increased in ''V. cholera'' infections and they repress the expression of several ''V. cholera'' virulence factors Virulence factors (preferably known as pathogenicity factors or effectors in plant science) are cellular structures, molecules and regulatory systems that enable microbial pathogens (bacteria, viruses, fungi, and protozoa) to achieve the following ....

Lachnospiraceae
The Lachnospiraceae are a family of obligately anaerobic, variably spore-forming bacteria in the order Eubacteriales that ferment diverse plant polysaccharides to short-chain fatty acids (butyrate, acetate) and alcohols (ethanol). These bacteria are among the most abundant taxa in the rumen The rumen, also known as a paunch, is the largest stomach compartment in ruminants and the larger part of the reticulorumen, which is the first chamber in the alimentary canal of ruminant animals. The rumen's microbial favoring environment al ... and the human gut microbiota. Members of this family may protect against colon cancer in humans by producing butyric acid. Lachnospiraceae have been found to contribute to diabetes in genetically susceptible (ob/ob) germ-free mice. References Further reading * * * * * * {{Taxonbar, from=Q3825240 Bacteria families ...

Crohn's Disease
Crohn's disease is a type of inflammatory bowel disease (IBD) that may affect any segment of the gastrointestinal tract. Symptoms often include abdominal pain, diarrhea (which may be bloody if inflammation is severe), fever, abdominal distension, and weight loss. Complications outside of the gastrointestinal tract may include anemia, skin rashes, arthritis, inflammation of the eye, and fatigue. The skin rashes may be due to infections as well as pyoderma gangrenosum or erythema nodosum. Bowel obstruction may occur as a complication of chronic inflammation, and those with the disease are at greater risk of colon cancer and small bowel cancer. While the precise causes of Crohn's disease (CD) are unknown, it is believed to be caused by a combination of environmental, immune, and bacterial factors in genetically susceptible individuals. It results in a chronic inflammatory disorder, in which the body's immune system defends the gastrointestinal tract, possibly targeting microbial ...
