Physical traits like obesity and leanness can be “transmitted” to mice, by inoculating the rodents with human gut microbes. A team of scientists led by Jeffrey Gordon from the Washington University School of Medicine in St. Louis found that germ-free mice put on weight when they were transplanted with gut microbes from an obese person, but not those from a lean person.
The team also showed that a “lean” microbial community could infiltrate and displace an “obese” one, preventing mice from gaining weight so long as they were on a healthy diet. The results were published today (September 5) in Science.
