On the Serengeti plain, gut bacteria reveal who’s been eating grass and who’s been sampling the gazelle.
What a mammal eats seems to determine the microbial species that live in its intestines and what jobs those microbes take on, an international team of researchers reports May 20 in Science. The nutrients inside meat and veggies predictably influence the different communities of friendly bacteria that inhabit both vegetarian and meat-eating species, the group says.
“This kind of work is foundational,” says Martin Blaser, a microbiologist at New York University who was not involved in this study. “It helps to define the macro rules that govern these things.”/.../
