Stress affects the balance of bacteria in the gut and immune response
Date:3/21/2011

New York, 21 March 2011 Stress can change the balance of bacteria that naturally live in the gut, according to research published this month in the journal Brain, Behavior, and Immunity.

"These bacteria affect immune function, and may help explain why stress dysregulates the immune response," said lead researcher Michael Bailey.

Exposure to stress led to changes in composition, diversity and number of gut microorganisms, according to scientists from The Ohio State University. The bacterial communities in the intestine became less diverse, and had greater numbers of potentially harmful bacteria, such as Clostridium.

"These changes can have profound implications for physiological function", explained Dr Bailey. "When we reduced the number of bacteria in the intestines using antibiotics, we found that some of the effects of stress on the immune system were prevented", he added. "This suggests that not only does stress change the bacteria levels in the gut, but that these alterations can, in turn, impact our immunity."

"This is the first evidence that the gut microorganisms may play a role in innate immunological stress responses," said Monika Fleshner, Professor of Integrative Physiology at the University of Colorado, Boulder. "The study reveals the dynamic interactions between multiple physiological systems including the intestinal microbiota and the immune system."

Because gut bacteria have been linked to diseases like inflammatory bowel disease, and even to asthma, a future goal of the study is to determine whether alterations of gut bacteria is the reason why these diseases tend to be worse during periods of pressure.
