So you might be wondering whether we can  also do this sort of thing across species, and it turns out that if you take microbes from an obese person and transplant them into mice you've raised germ-free, those mice will also become fatter than if they received the microbes from a lean person, but we can design a microbial community that we inoculate them with that prevents them from gaining this weight.
Estarédesvos preguntando se se poden facer estas cousas noutras especies. De collermos microbios dunha persoa obesa e transplantármolos en ratos que foron criados sen xermes, eses ratos acabarán tamén  por engordar máis que se recibisen os microbios dunha persoa delgada. Pero podemos deseñar a comunidade microbiana coa que inoculalos para evitar que engorden.
