Several years later, when you go to the doctor, the doctor may not ask
you allergic to anything, but also ask your intestinal type. From the
European Molecular Biology Laboratory (EMBL) and the International
Federation MetaHIT scientists found three different human intestinal
type. The study is published in the April 20 "natural" (Nature) online
edition.
We have a variety of intestinal bacteria, to help us digest food,
break down toxins, resulting in some vitamins and essential amino
acids, and resist the invaders. However, the composition of microbial
communities, there is still great difference between individuals.
This study leader Peer Bork spoke: "We found that the combination of
microorganisms in the human gut is not random. Our intestinal flora
can be divided into three different types."
Sanger sequencing team used four European countries (Denmark, France,
Italy and Spain) of 22 stool DNA samples of individuals were
sequenced. Then they will group these samples prior to microbiological
results were compared. Prior researchers have used Sanger sequencing
or pyrosequencing of 17 individuals from the United States and Japan,
the intestinal microbial groups.
Then they will study the extend to individuals in Denmark and the
United States 95 154 individuals. They found that, according to the
proliferation of intestinal bacterial species, all data can be divided
into three categories, that is, each person belongs to these three
types of a gut.
Scientists are not clear why different people have different
intestinal type, they speculate that this difference may lie in the
human immune system to distinguish between good bacteria and bad
bacteria, or with cells in different ways on the release of waste.
As blood type, these intestinal type and age, sex, race and body mass
index independent. But they also found that the elderly seem to have
more carbohydrates intestinal microbial genes, this may be because, as
we grew older, we deal with nutrients may be less efficient,
therefore, in order to survive, bacteria must assume the task.
Bork also said that at present there are some with age, weight and
other traits related to bacterial genes, which may be a marker of
obesity or disease, which may be meaningful in the diagnosis and
prognosis.
If this is true, then the diagnosis of a disease or assessment of the
possibility of someone suffering from specific diseases, the doctor
may look for clues from the bacteria. After diagnosis, treatment may
also be based on the patient's intestinal type, in order to ensure the
best results.
