Bacteriodes It is well known for violating ...

As the classification of blood, bacteria in our guts appear to fit into one of three categories, which have no relation to our nationality, age, gender and other characteristics, a new study shows. Study of genetic information in combination with about three dozen people in six countries, showing that all falls into one of three categories they dub enterotypes, which in their opinion, spread throughout the world as well as blood. People guts are home to swarms of bacteria. Members of this internal ecosystem help us all sorts of important tasks, such as food digestion, helping our immune system and strattera price production of nutrients such as vitamin K, and the study indicates a relationship between these 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 people in Denmark, France, Italy and Spain, and in combination with existing data from that population. Their analysis revealed three enterotypes determined by the relative abundance of different types of networks, according to study researcher Peer Bork, the head unit at the European Molecular Biology Laboratory in Germany. In general, the bacteria of the genus

Bacteriodes well known to destroy carbohydrates were the most common overall, accounting for about 12 percent of all bacteria in the samples, said Bork. In fact,

Bacteriodes dominated the first (and to a lesser extent the third) enterotype. Another group, Prevotella

,

was fairly plentiful in the second enterotype. Ruminococcus also makes an important contribution in the third enterotype. Enterotype man seemed to have no connection with their characteristics such as gender, age, body mass index or nationality. There was, however, a caveat: Enterotype one appeared to make a more powerful figure among the Japanese people, although this may be due to small sample size, which includes the data, only 13 Japanese, according to Bork. While the type of bacteria in the gut showed no connection with the host characteristics, this does not apply to the function of bacteria. For example, the presence of bacteria capable of breaking starch appears to someone with age. And people seem to spend more bacteria with a mechanism for the synthesis of aspartate, an amino acid. The findings, detailed in the latest issue of the journal Nature, have implications for where the treatment can be tailored to the needs of individuals. For example, we know that his gut bacteria help in the metabolism of drugs and changes in the absorption behavior of human cells. Its likely that the three enterotypes do it in different ways, so that the optimal dose of medication (and the balance of power) 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 living there with what he wrote.
