As the classification of blood, bacteria in our guts appear to fit into one of three categories that are not relevant to our nationality, age, sex and other characteristics, a new study shows. Study of genetic information in combination with about three dozen people in six countries, showing that it falls into one of three categories they duplicate enterotypes, which in their opinion, spread all over the world as well as blood. People intestine is home to swarms of bacteria. Members of this internal ecosystem help us all sorts of important tasks such as digesting food, helping our immune system and production of nutrients such as vitamin K and research indicates that there is a connection between the micro-organisms and some health problems, including obesity and inflammatory bowel disease.

Using an approach called metagenomics, researchers sequence the genetic material collected from the feces of 22 persons, of Denmark, France, Italy and Spain, and in combination with existing, that data from people. Their analysis showed three enterotypes determined by the relative abundance of different types of networks, according to study researcher Peer Bork, head unit in the European Molecular Biology Laboratory in Germany. In general, bacteria type
Bacteriodes well known to destroy carbohydrates are the most common overall, which is about 12 percent of all bacteria in samples, said Bork. In fact,
Bacteriodes dominated the first (and to a lesser extent the third) enterotype. Another group, Prevotella
,
was quite abundant in the second enterotype. Ruminococcus also makes an important contribution in the third enterotype. Enterotype man seemed purchase strattera to have no relation to their characteristics such as gender, age, body mass index or nationality. There was, however, a caveat: Enterotype one appeared to make more powerful figure among the Japanese people, although this may be the result of small sample size, which included data only 13 Japanese, according to Bork. While the type of bacteria in the gut showed no connection with the hosts performance is not related to the function of bacteria. For example, the presence of bacteria capable of breaking down starch appears from under someone. And people seem to spend more bacteria with a mechanism for the synthesis of aspartate, amino acids. The study, detailed in the latest issue of the journal Nature, have implications for where treatment can be tailored to the needs of people. For example, we know that his gut bacteria help in the metabolism of drugs and change the absorption behavior of human cells. Its likely that the three enterotypes do it differently, so that optimal doses of drugs (and balance of food) may be different for each enterotype, Bork wrote in a letter to LiveScience. Knowledge of enterotypes may also help in developing methods to restore healthy gut communities, not to kill all the bugs that live there with, he wrote.
