Researchers in Shanghai identified a human bacteria linked with obesity, fed it  to mice and compared their weight gain with rodents without the bacteria. The  latter did not become obese despite being fed a high-fat diet and being  prevented from exercising.

The bacteria linked to obesity is “enterobacter” and the research is peer reviewed and published in the International Society for Microbial Ecology.
