UW–Madison’s new Gnotobiotic Shared Resource (GSR) is expanding opportunities for researchers to study the microbiome in germ-free and gnotobiotic mouse models. The centralized facility was established with a $1 million gift from the Wisconsin Alumni Research Foundation (WARF) through the Office of the Vice Chancellor for Research’s Microbiome Initiative.
The GSR was recently highlighted at the WID-hosted UW–Madison Microbiome Symposium, where this year’s “Gut-Brain Axis” theme reflected the work of many researchers using the facility to study how the gut microbiome may influence neurological function.
“The GSR is an amazing gift to the campus,” says Wisconsin Institute for Discovery director and GSR user Jo Handelsman. “Relatively few campuses have gnotobiotic facilities for general use. Usually they are located in one research group which must coordinate their own training, personnel, and maintenance of colonies. The UW–Madison GSR makes possible new avenues of microbiome investigation for our researchers.”
