Is Obesity An Oral Bacterial Disease?

By | July 9, 2009 scientific team from The Forsyth Institute has discovered new links between certain oral bacteria and obesity. In a recent study, the researchers demonstrated that the salivary bacterial composition of overweight women differs from non-overweight women. This preliminary work may provide clues to interactions between oral bacteria and the pathology of obesity. This research may help investigators learn new avenues for fighting the obesity epidemic.This work will be published in the Journal of Dental Research.”There has been a world-wide explosion of obesity, with many contributing factors,” said Dr. J. Max Goodson, senior author of the study. “However, the inflammatory nature of the disease is also recognized. This led me to question potential unknown contributing causes of obesity. Could it be an epidemic involving an infectious agent?” “It is exciting to image the possibilities if oral bacteria are contributing to some types of obesity,” added Goodson.

… more than 98 percent of the overweight women could be identified by the presence of a single bacterial species, called Selenomanas noxia, at levels greater than 1.05 percent of the total salivary bacteria. These data suggest that the composition of salivary bacteria changes in overweight women. It seems likely that these bacterial species could serve as indicators of a developing overweight condition and possibly be related to the underlying causation.
