CHICAGO — A cold-like virus may cause obesity, new experiments suggest.
Researchers at the University of Wisconsin in Madison have found that mice and chickens infected with a common human virus put on much more fat than uninfected animals. They have also discovered that the same virus is more prevalent among overweight people, a strong indication that it may also cause obesity in humans.
In four experiments, the Wisconsin researchers inoculated chickens and mice with adenovirus-36, a member of a viral family that includes about 50 strains. Most adenoviruses cause colds, diarrhea or pinkeye.
