The Gnotobiotics Facility supports research focused on the role of microbiota in cancer inflammation, pathogenesis, and response to treatment. We specialize in raising germ-free (axenic) mice as well as mice with a defined microbiome (gnotobiotic). 

Examining the role of microbes on cancer biology 

The Gnotobiotics Facility assists research efforts aimed at benefiting human health. We examine the roles that specific microbes have on cancer biology and assess how they can be targeted to benefit patients.

Specialized technology and expertise

The facility can rederive mice into germ-free status, expand colonies of axenic and gnotobiotic mice, and maintain microbiome-defined lines of animals. In addition, we work with a variety of mouse models, particularly in the fields of immunology and cancer research.
