Gnotobiotics Core Facility

Overview of Services

Gnotobiotics is derived from the Greek gnosos, meaning known, and bios, meaning life. This technology enables the breeding and maintenance of germ-free animals that are devoid of any associated microorganisms, including bacteria, archaea, microscopic fungi, parasites, and viruses. 

The mission of the Gnotobiotics Core is to enable UCSF researchers to perform experiments introducing defined microbes or microbial consortia to test their impact on host physiology and disease.
