Bacteria in the Intestine Affect Human Behavior

Thousands of live bacteria in the human gut. In addition to providing benefits, the presence of the bacteria, sometimes also harm humans.

A recent study revealed that bacteria in the gut can influence human behavior.

According to a study conducted by researchers from McMaster University, the bacteria in the gut can affect chemicals in the brain and affect human behavior. This finding is very important, because these types of stomach ailments, including irritable bowel, often associated with anxiety or depression.

In addition, there is also speculation that psykologi problems, such as symptoms of autism, linked to the bacteria contained within the gut.

"The results were amazing provide impetus for further penelitihan against disease-causing microbes component behavior," said the professor of medicine and researcher Michael G. DeGroote School of Medicine, Stephen Collins as reported

Collin and his assistant, Premysl Bercik doing research at the Institute Farncombe Family Digestive Health Research (UK).

In that study, it was found that in the gut of each person there are about 1,000 trillium bacteria that live in comfort, and in harmony with human life. These bacteria perform a number of functions vital to health, which absorbs energy from food, protection against infections and provide nutrition to the cells in the intestine.

However, if the 'good life' of bacteria is disturbed, it will impact the human condition. Any disruption to life-threatening conditions, such as infection of the colon caused by antibiotics.

To prove the bacteria can influence behavior, the researchers took a bacteria-free mice, and then gave the bacteria from mice with aggressive behavior.

As a result, after the mice were given the bacteria that behave aggressively, bacteria-free mice and initially silent it turned into aggressive and bolder.

The same study also showed that mice initially be passive aggressive when given the bacteria from mice that behave passively.

Meanwhile, previous studies focused on the role of bacteria in the early development of the brain. Collin said recent research indicates that although many factors determine behavior, the nature and stability of bacteria in the gut may influence the behavior and any disruption. Both disorders are caused by antibiotics or infection, may contribute to changes in behavior.
