When we take the microbes from an obese mouse and transplant them into a genetically normal mouse that's been raised in a bubble with no microbes of its own, it becomes fatter than if it got them  from a regular mouse.
Kad uzmemo mikrobe sa pretilog miša i presadimo ih u genetski normalnog miša koji je uzgojen u mjehuru bez vlastitih mikroba, postaje deblji nego ako ih dobije od običnog miša.
