      Study: The right bacteria might help fight obesity

      WASHINGTON (AP) -- The right type of germs might be able to help fight fat.

      That's the finding of scientists at Washington University in St. Louis. They say different kinds of bacteria that live inside the gut can help spur obesity or protect against it.

      The researchers transplanted intestinal germs from fat or skinny people into mice, and watched the rodents change. And whether or not the good germs could move in and do their job was determined by what they ate.

      The report raises the possibility of one day turning gut bacteria into personalized fat-fighting therapies. And it may also help explain why some people have a harder time losing weight than others do.

      The research is reported in the journal Science.
