The
germs that can live in the intestines help cause obesity and a number
of health symptoms that together with him, according to the researchers. It
could be that some bacteria causes inflammation and loss of appetite
disorders such as inflammatory bowel diseases Crohn's and colitis can
cause, the researchers report in the journal Science.
In other words, the seeds that you eat too much, Andrew Gewirtz of Emory University in Atlanta, and colleagues.
"Previous studies have suggested that bacteria can influence how energy is absorbed by the food, but these results show that intestinal bacteria can actually influence appetite," Gewirtz said.
"Why do people eat more?"
"The obesity epidemic is of people who are driven to eat too much, but why do some people eat more?"
Gewirtz said the research suggests that bacteria play a role - perhaps a population of bacteria that thrive because other organisms, the competition has been destroyed by antibiotics, access to clean drinking water and other factors of modern life.
His team ran the results through accident.
"We have mice is examined with colitis," Gewirtz said in a telephone interview.
The team suspects a kind of germ was responsible, then they are transferred mouse embryos into surrogate mothers, do not get infected from their mothers.
Babies are colonized by bacteria and other microorganisms shortly after birth and the composition of these colonies - who still live in the skin and intestines - are very similar to those of the mother.
Colitis was better, but the baby mice became obese and developed metabolic syndrome - a collection of symptoms, high cholesterol, excess fat around the waist, high blood pressure and insulin resistance includes.
Insulin resistance means that the body does not effectively use insulin to the food and Gewirtz believes that can be the key.
Previous studies
The researchers found a new study in the normal mice became obese and lean fat in the diet of mouse intestinal bacteria.
They worked with the team, including Ruth Ley of Cornell University in New York to see what is the role of intestinal bacteria may play.
"What we think, is that the mice are susceptible to intestinal inflammation," Gewirtz said. "If you have a large number of inflammatory signals about, insulin is not working properly."
Weeks of treatment with antibiotics has contributed to and diets.
"If we take the consumption of foods that are generally good, and certainly not obese limit," he said. "They are, however, insulin-resistant."
The identification of microorganisms
Gewirtz team is now working to see if they can identify the microorganisms involved. They are working to see if obese people have unique patterns of intestinal bacteria.
Scientists know that hundreds of species of bacteria live in the intestines and the average person has about 2 kg, worth. Chinese scientists recently in the journal Nature reported that they had found 1,000 different species in the intestines of humans.
Sun obesity was by taking an antibiotic to kill germs that eat people to make offensive treat?
"It is very difficult to replace the bacteria that we have," Gewirtz said. Studies have already shown that it is difficult to treat conditions like Crohn's disease, even with antibiotics months.
